Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] The present application claims the benefits of and priority,
under 35 U.S.C. .sctn. 119(e), to U.S. Provisional Application No.
62/537,820 filed Jul. 27, 2018 by Nogueira-Nine et al and entitled
"Low Cost Battery-less Light Switch Architecture and Pairing
Method" of which the entire disclosure is incorporated herein by
reference for all purposes.
FIELD OF THE DISCLOSURE
[0002] Embodiments of the present disclosure relate generally to
methods and systems for controlling light sources and more
particularly to wireless pairing of light switches to one or more
light drivers controlling light sources.
BACKGROUND
[0003] In the area of smart lighting, the radio technology
Bluetooth Low Energy (BLE) has been established as the de facto
communication standard because of the widespread use of this
technology and the availability of BLE in most of today's
smartphones. However, in many use cases, the communication range
provided by BLE is not sufficient if, for example, the
communication parts (e.g., the light switch and/or the light
driver) are farther away than what BLE can provide for range, e.g.,
the devices are not in the same room. Having a BLE receiver in the
light driver has the benefit of enabling smartphones to control the
lights but having BLE in the light switch does not give any added
value to the system. Furthermore, the home lighting sector is
highly price sensitive and there are other less complex wireless
technologies able to do the job with less cost. Hence, there is a
need for improved methods and systems for controlling light
sources.
BRIEF SUMMARY
[0004] Embodiments of the disclosure provide systems and methods
for wireless pairing of light switches to one or more light drivers
controlling light sources. According to one embodiment, a lighting
system can comprise a light source and a light switch. The light
switch can comprise a binary switch, a wireless transmitter, a
processor, and a memory coupled with and readable by the processor
and storing therein a code identifying the light switch. A light
driver can be coupled with the light source. The light driver can
comprise a pairing switch, a wireless receiver, a processor, and a
memory coupled with and readable by the processor and storing
therein a set of instructions which, when executed by the
processor, causes the processor to pair with the light switch by
receiving, from the pairing button, a first input indicating a
start of a pairing mode, initiating the pairing mode based on the
first input, and determining whether a message is received from the
light switch within a first predetermined period of time.
[0005] The instructions stored in the memory of the light switch,
when executed by the processor of the light switch, can cause the
processor to detect an operation of the binary switch and send, in
response to detecting the operation of the binary switch, the
message through the wireless transmitter to the wireless receiver
of the light driver. The code identifying the light switch can be
used to modulate the message. In response to determining the
message is received from the light switch within the first
predetermined period of time, the light driver can read the code
identifying the light switch modulated into the message and store
the code identifying the light switch in the memory of the light
driver. Alternatively, the light driver can terminate the pairing
mode in response to determining the message is not received from
the light switch within the first predetermined period time.
[0006] The instructions stored in the memory of the light switch,
when executed by the processor of the light switch, can cause the
processor to detect an operation of the binary switch. The
operation of the binary switch can place the binary switch into one
of an on position or an off position. In response to detecting the
operation of the binary switch places the binary switch into the on
position, the switch can send, through the wireless transmitter, a
command to turn on the light source coupled with the light driver.
The code identifying the light switch can be modulated into the
command. The light driver can receive, through the wireless
receiver, the command from the light switch, demodulate the
received command from the light switch using the code identifying
the light switch stored in the memory of the light driver, and turn
the light on based on the demodulated command. In response to
detecting the operation of the binary switch places the binary
switch into the off position, the light switch can send, through
the wireless transmitter, a command to turn off the light source
coupled with the light driver. Again, the code identifying the
light switch can be modulated into the command. The light driver
can receive, through the wireless receiver, the command from the
light switch, demodulate the received command from the light switch
using the code identifying the light switch stored in the memory of
the light driver, and turn the light off based on the demodulated
command.
[0007] The instructions stored in the memory of the light driver,
when executed by the processor of the light driver, can further
cause the light driver to receive, from the pairing button, a
second input indicating a start of a de-pairing mode. In response
to the second input, the processor of the light driver can delete
the code identifying the light switch stored in the memory of the
light driver.
[0008] In some cases, the lighting system can further comprise a
wireless device, the wireless device can comprise a processor and a
memory having stored therein a set of instructions which, when
executed by the processor, causes the processor to pair with the
light driver through the wireless receiver of the light driver.
Pairing with the light driver can comprise sending, from the
wireless device to the wireless receiver of the light driver, a
message modulated with a pairing code. The pairing code can be used
by the light driver to identify the wireless device. The wireless
device can further control the light source through the light
driver. Controlling the light source through the light driver can
comprise sending, from the wireless device to the wireless receiver
of the light driver, a command modulated with the pairing code. The
light driver can then control the light source based on the
command.
[0009] According to another embodiment, a light driver can comprise
a pairing switch, a wireless receiver, a processor, and a memory
coupled with and readable by the processor and storing therein a
set of instructions which, when executed by the processor, causes
the processor to pair with a light switch by receiving, from the
pairing button, a first input indicating a start of a pairing mode,
initiating the pairing mode based on the first input, and
determining whether a message is received from the light switch
within a first predetermined period of time. In response to
determining the message is received from the light switch within
the first predetermined period of time, the light driver can read a
code identifying the light switch modulated into the message and
store the code identifying the light switch in the memory of the
light driver. Alternatively, the light driver can terminate the
pairing mode in response to determining the message is not received
from the light switch within the first predetermined period
time.
[0010] The instructions can further cause the light driver to
receive, through the wireless receiver, a command from the light
switch, demodulate the received command from the light switch using
the code identifying the light switch stored in the memory of the
light driver, and turn on a light coupled with the light driver on
based on the demodulated command. Additionally, or alternatively,
the instructions can cause the light driver to receive, through the
wireless receiver, a command from the light switch, demodulate the
received command from the light switch using the code identifying
the light switch stored in the memory of the light driver, and turn
off a light coupled with the light driver based on the demodulated
command.
[0011] In some cases, the instructions can further cause the light
driver to receive, from the pairing button, a second input
indicating a start of a de-pairing mode. In response to the second
input, the instructions can cause the processor of the light driver
to delete the code identifying the light switch stored in the
memory of the light driver.
[0012] According to yet another embodiment, a light switch can
comprise a binary switch, a wireless transmitter, a processor, and
a memory coupled with and readable by the processor and storing
therein a code identifying the light switch and a set of
instructions which, when executed by the processor, cause the
processor to pair with a wireless light driver through the wireless
transmitter using the code identifying the light switch. Pairing
with the light driver can comprise detecting an operation of the
binary switch and sending, in response to detecting the operation
of the binary switch, a message through the wireless transmitter to
a wireless receiver of the light driver, wherein the code
identifying the light switch can be modulated into the message. The
instructions can further cause the light switch to detect an
operation of the binary switch, the operation of the binary switch
placing the binary switch into one of an on position or an off
position. In response to detecting the operation of the binary
switch places the binary switch into the on position, the
instructions can cause the processor of the light switch to send,
through the wireless transmitter, a command to turn on the light
source coupled with the light driver, wherein the code identifying
the light switch is modulated into the command. In response to
detecting the operation of the binary switch places the binary
switch into the off position, the instructions can cause the
processor of the light switch to send, through the wireless
transmitter, a command to turn off the light source coupled with
the light driver, wherein the code identifying the light switch is
modulated into the command.

DETAILED DESCRIPTION
[0019] In the following description, for the purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of various embodiments disclosed
herein. It will be apparent, however, to one skilled in the art
that various embodiments of the present disclosure may be practiced
without some of these specific details. The ensuing description
provides exemplary embodiments only, and is not intended to limit
the scope or applicability of the disclosure. Furthermore, to avoid
unnecessarily obscuring the present disclosure, the preceding
description omits a number of known structures and devices. This
omission is not to be construed as a limitation of the scopes of
the claims. Rather, the ensuing description of the exemplary
embodiments will provide those skilled in the art with an enabling
description for implementing an exemplary embodiment. It should
however be appreciated that the present disclosure may be practiced
in a variety of ways beyond the specific detail set forth
herein.
[0020] While the exemplary aspects, embodiments, and/or
configurations illustrated herein show the various components of
the system collocated, certain components of the system can be
located remotely, at distant portions of a distributed network,
such as a LAN and/or the Internet, or within a dedicated system.
Thus, it should be appreciated, that the components of the system
can be combined in to one or more devices or collocated on a
particular node of a distributed network, such as an analog and/or
digital telecommunications network, a packet-switch network, or a
circuit-switched network. It will be appreciated from the following
description, and for reasons of computational efficiency, that the
components of the system can be arranged at any location within a
distributed network of components without affecting the operation
of the system.
[0021] Furthermore, it should be appreciated that the various links
connecting the elements can be wired or wireless links, or any
combination thereof, or any other known or later developed
element(s) that is capable of supplying and/or communicating data
to and from the connected elements. These wired or wireless links
can also be secure links and may be capable of communicating
encrypted information. Transmission media used as links, for
example, can be any suitable carrier for electrical signals,
including coaxial cables, copper wire and fiber optics, and may
take the form of acoustic or light waves, such as those generated
during radio-wave and infra-red data communications.
[0022] As used herein, the phrases "at least one," "one or more,"
"or," and "and/or" are open-ended expressions that are both
conjunctive and disjunctive in operation. For example, each of the
expressions "at least one of A, B and C," "at least one of A, B, or
C," "one or more of A, B, and C," "one or more of A, B, or C," "A,
B, and/or C," and "A, B, or C" means A alone, B alone, C alone, A
and B together, A and C together, B and C together, or A, B and C
together.
[0023] The term "a" or "an" entity refers to one or more of that
entity. As such, the terms "a" (or "an"), "one or more" and "at
least one" can be used interchangeably herein. It is also to be
noted that the terms "comprising," "including," and "having" can be
used interchangeably.
[0024] The term "automatic" and variations thereof, as used herein,
refers to any process or operation done without material human
input when the process or operation is performed. However, a
process or operation can be automatic, even though performance of
the process or operation uses material or immaterial human input,
if the input is received before performance of the process or
operation. Human input is deemed to be material if such input
influences how the process or operation will be performed. Human
input that consents to the performance of the process or operation
is not deemed to be "material."
[0025] The term "computer-readable medium" as used herein refers to
any tangible storage and/or transmission medium that participate in
providing instructions to a processor for execution. Such a medium
may take many forms, including but not limited to, non-volatile
media, volatile media, and transmission media. Non-volatile media
includes, for example, NVRAM, or magnetic or optical disks.
Volatile media includes dynamic memory, such as main memory. Common
forms of computer-readable media include, for example, a floppy
disk, a flexible disk, hard disk, magnetic tape, or any other
magnetic medium, magneto-optical medium, a CD-ROM, any other
optical medium, punch cards, paper tape, any other physical medium
with patterns of holes, a RAM, a PROM, and EPROM, a FLASH-EPROM, a
solid state medium like a memory card, any other memory chip or
cartridge, a carrier wave as described hereinafter, or any other
medium from which a computer can read. A digital file attachment to
e-mail or other self-contained information archive or set of
archives is considered a distribution medium equivalent to a
tangible storage medium. When the computer-readable media is
configured as a database, it is to be understood that the database
may be any type of database, such as relational, hierarchical,
object-oriented, and/or the like. Accordingly, the disclosure is
considered to include a tangible storage medium or distribution
medium and prior art-recognized equivalents and successor media, in
which the software implementations of the present disclosure are
stored.
[0026] A "computer readable signal" medium may include a propagated
data signal with computer readable program code embodied therein,
for example, in baseband or as part of a carrier wave. Such a
propagated signal may take any of a variety of forms, including,
but not limited to, electro-magnetic, optical, or any suitable
combination thereof. A computer readable signal medium may be any
computer readable medium that is not a computer readable storage
medium and that can communicate, propagate, or transport a program
for use by or in connection with an instruction execution system,
apparatus, or device. Program code embodied on a computer readable
medium may be transmitted using any appropriate medium, including
but not limited to wireless, wireline, optical fiber cable, RF,
etc., or any suitable combination of the foregoing.
[0027] The terms "determine," "calculate," and "compute," and
variations thereof, as used herein, are used interchangeably and
include any type of methodology, process, mathematical operation or
technique.
[0028] It shall be understood that the term "means" as used herein
shall be given its broadest possible interpretation in accordance
with 35 U.S.C., Section 112, Paragraph 6. Accordingly, a claim
incorporating the term "means" shall cover all structures,
materials, or acts set forth herein, and all of the equivalents
thereof. Further, the structures, materials or acts and the
equivalents thereof shall include all those described in the
summary of the disclosure, brief description of the drawings,
detailed description, abstract, and claims themselves.
[0029] Aspects of the present disclosure may take the form of an
entirely hardware embodiment, an entirely software embodiment
(including firmware, resident software, micro-code, etc.) or an
embodiment combining software and hardware aspects that may all
generally be referred to herein as a "circuit," "module" or
"system." Any combination of one or more computer readable
medium(s) may be utilized. The computer readable medium may be a
computer readable signal medium or a computer readable storage
medium.
[0030] In yet another embodiment, the systems and methods of this
disclosure can be implemented in conjunction with a special purpose
computer, a programmed microprocessor or microcontroller and
peripheral integrated circuit element(s), an ASIC or other
integrated circuit, a digital signal processor, a hard-wired
electronic or logic circuit such as discrete element circuit, a
programmable logic device or gate array such as PLD, PLA, FPGA,
PAL, special purpose computer, any comparable means, or the like.
In general, any device(s) or means capable of implementing the
methodology illustrated herein can be used to implement the various
aspects of this disclosure. Exemplary hardware that can be used for
the disclosed embodiments, configurations, and aspects includes

[0035] Various additional details of embodiments of the present

[0036] It is with respect to the above issues and other problems
that the embodiments presented herein were contemplated. In
general, embodiments of the present disclosure provide methods,
devices, and systems by which lights in a building can be
controlled
[0037] As shown in FIG. 1, a lighting environment 100 can include a
light switch 104 and a light driver 108 in wireless communication,
through wireless link/channel 116. The light driver 108 powers the
light 112 based on commands from the light switch 104.
[0038] Referring now to FIGS. 2A though 2C, the light switch 104
and/or light driver 108 can use a mixed and asymmetric solution
employing a cheap frequency-shift keying (FSK) only transmitter 208
(or other suitable transmitter) in the light switch 104 and a FSK
Receiver 212 and/or a BLE transceiver 216 (or other suitable
receiver(s)) in the light driver 108. The light switch 104 can
comprise a FSK transmitter 208, a memory 204, which may be an
electrically erasable programmable read-only memory (EEPROM) or
other suitable memory device, storing a unique code and an
ultra-low cost digital encoder 206. When the binary switch 210 is
pressed, the encoder 206 reads the code stored in the memory 204
and modulates such a code in a radio signal by using FSK modulation
with the FSK transmitter 208.
[0039] Further, the light driver can include an FSK receiver 212, a
microcontroller (MCU) with memory and possibly with a BLE
transceiver 216, and a pairing button (not shown). Ideally, because
of cost issues and integration level, the MCU and the BLE
transceiver can be combined in a System-on-Chip (SoC) 216. The FSK
receiver 212, in the light driver 108, may always be on and ready
to receive a signal coming from the light switch 104.
[0040] Stated another way, a lighting system 100 can comprise a
light source 112 and a light switch 104. The light switch can
comprise a binary switch 210, a wireless transmitter 208, a
processor 206, and a memory 204 coupled with and readable by the
processor 206 and storing therein a code identifying the light
switch 104. A light driver 108 can be coupled with the light source
112. The light driver 108 can comprise a pairing switch 218, a
wireless receiver 212, a processor 216, and a memory coupled with
and readable by the processor 216 and storing therein a set of
instructions which, when executed by the processor 216, causes the
processor 216 to pair with the light switch 104 by receiving, from
the pairing button 218, a first input indicating a start of a
pairing mode, initiating the pairing mode based on the first input,
and determining whether a message is received from the light switch
104 within a first predetermined period of time.
[0041] The instructions stored in the memory of the light switch,
when executed by the processor of the light switch 104, can cause
the processor 206 to detect an operation of the binary switch 210
and send, in response to detecting the operation of the binary
switch 210, the message through the wireless transmitter 208 to the
wireless receiver 212 of the light driver 108. The code can
identifying the light switch 104 can be used to modulate the
message. In response to determining the message is received from
the light switch 104 within the first predetermined period of time,
the light driver 108 can read the code identifying the light switch
modulated into the message and store the code identifying the light
switch in the memory of the light driver 108. Alternatively, the
light driver 108 can terminate the pairing mode in response to
determining the message is not received from the light switch 104
within the first predetermined period time.
[0042] The instructions stored in the memory of the light switch
104, when executed by the processor 206 of the light switch 104,
can cause the processor to detect an operation of the binary switch
210. The operation of the binary switch 210 can place the binary
switch 210 into one of an on position or an off position. In
response to detecting the operation of the binary switch 210 places
the binary switch 210 into the on position, the switch 104 can
send, through the wireless transmitter 208, a command to turn on
the light source 112 coupled with the light driver 108. The code
identifying the light switch 104 can be modulated into the command.
The light driver 108 can receive, through the wireless receiver
212, the command from the light switch 104, demodulate the received
command from the light switch 104 using the code identifying the
light switch 104 stored in the memory of the light driver 108, and
turn the light 112 on based on the demodulated command. In response
to detecting the operation of the binary switch 210 places the
binary switch 210 into the off position, the light switch 104 can
send, through the wireless transmitter 208, a command to turn off
the light source 112 coupled with the light driver 108. Again, the
code identifying the light switch 104 can be modulated into the
command. The light driver 108 can receive, through the wireless
receiver 212, the command from the light switch 104, demodulate the
received command from the light switch 104 using the code
identifying the light switch 104 stored in the memory of the light
driver 108, and turn the light 112 off based on the demodulated
command.
[0043] The instructions stored in the memory of the light driver
108, when executed by the processor 216 of the light driver 108,
can further cause the light driver 108 to receive, from the pairing
button 218, a second input indicating a start of a de-pairing mode.
In response to the second input, the processor 216 of the light
driver 108 can delete the code identifying the light switch 104
stored in the memory of the light driver 108.
[0044] FIG. 3 is another block diagram of a lighting system in
accordance with embodiments of the present disclosure. In some
cases and as illustrated in this example, the lighting system can
further comprise a wireless device 308. The wireless device 308 can
comprise a processor and a memory having stored therein a set of
instructions which, when executed by the processor, causes the
processor to pair with the light driver 108 through the wireless
receiver 212 of the light driver 108. Pairing with the light driver
108 can comprise sending, from the wireless device 308 to the
wireless receiver 212 of the light driver 108, a message modulated
with a pairing code. The pairing code can be used by the light
driver 108 to identify the wireless device 308. The wireless device
308 can further control the light source 112 through the light
driver 108. Controlling the light source 112 through the light
driver 108 can comprise sending, from the wireless device 308 to
the wireless receiver 212 of the light driver 108, a command
modulated with the pairing code. The light driver 108 can then
control the light source 112 based on the command.
[0045] Now referring to the method 400 in FIG. 4, when the pairing
button on the light driver 108 is pressed for a predetermined
period of time, e.g., between 1 and 5 seconds, the MCU 216 of the
light driver 108 enters the pairing mode and awaits a FSK signal
116, from the light switch 104, with code information. This code
information is stored in the memory in the SoC 216 and the light
switch 104 is registered on the light driver 108, in step 408. This
pairing process 408 can be repeated with multiple light switches
104 so same light 112 can be operated from several light switches
104.
[0046] Optionally, in step 412, the light driver 108 can de-pair
one or more devices. For example, by pressing the pairing button on
the light driver 108 for a predetermined period of time, e.g., for
more than 5 seconds, all the codes stored in the driver memory on
the SoC 216 will be deleted. Upon deleting the codes, the light
switch 104 and all other devices are de-paired from the light
driver 108.
[0047] In step 416, the light switch encoder 206 of the light
switch 104 can now send on/off commands to the light driver 108,
which compares the transmitted code in the FSK signal with codes
stored in the memory of the SoC 216 to identify and verify the
light switch 104 is on the list of registered devices that can
operate this light driver 108. When verified, the SoC 216 of the
light driver 108 can send a signal to a relay 304 to control the
light 112, in step 420.
[0048] Further, a wireless device 308 may also control the light
driver 108, in steps 416/420. The light driver 108 can include a
BLE transceiver on the SoC 216. Thus, a wireless device 308 with
BLE technology can directly commute with the light driver 108 to
turn the light 112 ON and OFF. The pairing between the wireless
device 308 and the light driver 108 may take place like a standard
BLE pairing process, or the smartphone 304 can be used to scan a QR
code from a sticker in or on the light switch 108 that encodes the
unique light switch code. Then, the wireless device 308 can be used
to operate the light 112 without the need to pair the wireless
device 308 with every singled light driver 108. Rather, the
wireless device 308 can send one light switch code, in the BLE
message, to the driver 108.
[0049] With this improved procedure, it is also possible to create
a list of light switch codes that can be transferred form one
wireless device 308 to another without having to proceed with the
pairing process again.
