Description
RELATED APPLICATION
[0001] This present application claims benefit of the Chinese
Application CN 201610470932.1, filed on Jun. 22, 2016.
BACKGROUND
1. Technical Field
[0002] The present application relates to a lighting controlling
device, and more particularly to an automatic sensing system and an
automatic sensing control method for LED lighting.
2. Description of the Related Art
[0003] Light emitting diode (LED) is growing in popularity due to
decreasing costs and long life compared to incandescent lighting
and fluorescent lighting. Recently, a number of LED lighting
apparatuses have been designed to replace the halogen apparatus, as
well as other traditional incandescent or fluorescence lighting
apparatuses. In some places such as exhibition halls, jewelry
stores, museums, supermarkets, and some home lighting, such as
large villas, will use a lot of strip LED lamps. Moreover, in
addition to lighting equipments, such as general traffic lights,
billboards, motor-lights, etc., also use light-emitting diodes as
light source. As described above, for the light-emitting diodes as
a light source, the advantage is power saving, and the greater
brightness. Therefore, the use has been gradually common.
[0004] Since the pace of life in modern society is getting faster
and faster, people are increasingly in need of more simple control
of lighting equipment so as to obtain a comfortable life and more
sensitive more lighting. Therefore, the home intelligent control
lighting system is more and more used. However, the current home
intelligent control system generally requires the user via a remote
controller to continuously adjust brightness for changing the
corresponding brightness of the lamp or continuously adjust color
temperature for switching between the cool color and the warm color
so as to achieve best lighting effect. As a result, the intelligent
control device of the home intelligent control lighting system in
the prior art has a problem of complicated operation and is not
conducive to large-scale use in the general user base.
[0005] Therefore, it is necessary to provide an automatic sensing
system and an automatic sensing control method for LED lighting
which makes it possible to simply operate.

[0006] Many aspects of the embodiments can be better understood
with references to the following drawings. The components in the

being placed upon clearly illustrating the principles of the
embodiments. Moreover, in the drawings, like reference numerals
designate corresponding parts throughout two views.
[0007] FIG. 1 is a block diagram of an automatic sensing system for
LED lighting according to an embodiment.
[0008] FIG. 2 is a flow chart of an automatic sensing control
method for LED lighting according to an embodiment.
DETAILED DESCRIPTION
[0009] The present application is illustrated by way of example and
not by way of limitation in the figures of the accompanying
drawings. It should be noted that references to "an" or "one"
embodiment in this application are not necessarily to the same
embodiment, and such references mean at least one.
[0010] Referring to FIG. 1, an automatic sensing system 100 for LED
lighting is shown. The automatic sensing system for LED lighting
100 includes at least one LED lamp 10, and at least one sensing
control device 20 electrically connected to the at least one LED
lamp 10 and configured for controlling the at least one LED lamp
10. It can be understood that the automatic sensing system 100 for
LED lighting further includes other function modules, such as power
supply module, switch module, wires, and so on, which is well known
for these persons skilled in the art and not described in
detail.
[0011] The LED lamp 10 may be a lamp set independently in the
illumination system and may be a ceiling lamp, either a wall
washer, or a lawn lamp, which may include multiple, such as three,
five or more, or only one. The LED lamp 10 belongs to the prior art
and is known to those skilled in the art and will not be described
here. It is need to further explain that since lamps will usually
start to supplement the illumination when brightness are in the
lack, it is first necessary to classify the brightness so as to
achieve the purpose of automatic control. That is to say, the LED
lamp 10 will be operated in different operating modes at different
brightness levels. In the present embodiment, the brightness level
includes three stages. The brightness of the first stage is greater
than 200 lumens, the brightness of the second stage is less than
200 lumens and greater than 1 lumen, and the brightness level of
the third stage is less than 1 lumen. At the first stage, it is
generally considered that the brightness is sufficient and the LED
lamp 10 is not required to work or operate. And in the second
stage, the brightness is not sufficient, it is need the LED lamp 10
to work to compensate for the brightness when need to turn on the
LED lamp 10. Finally, in the third stage, it may be regarded that
it is no light into the night in the current environment, and the
LED lamp 10 should work in low light mode. That is, only a slight
brightness is issued to avoid irritating the human eye. Therefore,
the LED lamp 10 can be operated in at least three operation modes.
The at least three operation modes includes a closed mode, a low
light mode, and a fill light mode.
[0012] The sensing control device 20 includes an illumination
detection module 21, a pyroelectric sensing module 22, a signal
processing module 23, and a lamp control module 24. The
illumination detection module 21 is configured for detecting
brightness of the current environment. The pyroelectric sensing
module 22 is configured for sensing the infrared rays radiated by
the human body in the current environment. The signal processing
module 23 is configured for processing the signal data sensed by
the pyroelectric sensing module 22 in accordance with the signal
data detected by the illumination detection module 21 and
outputting control signal. The lamp control module 24 is configured
for controlling the LED lamp 10 to work in one mode of the three
operation modes according to the control signal from the signal
processing module 23. It is to be understood that the structure,
the operating principle and the electrical connection method of the
illumination detection module 21, the pyroelectric sensing module
22, the signal processing module 23, and the lamp control module 24
should be known to those skilled in the art. In the normal
operating state, the illumination detection module 21 always
detects the brightness of the current environment, and outputs the
control signal according to the brightness level of the current
environment. That is to say, when the brightness is at the first
stage, a closing signal is outputted, and when the brightness is at
the other stages, a turning-on signal is outputted. The
pyroelectric sensing module 22 starts to sense whether or not
someone is present in the current environment, that is, whether or
not the infrared ray is radiated, only when the turning-on signal
of the illumination detection module 21 is received thereby. When
someone presents in the current environment, the pyroelectric
sensing module 22 will output the control signal so that all of the
LED lamps 10 are operated in the fill light mode or the low light
mode. Therefore, the signal processing module 22 processes the
control signal outputted from the pyroelectric sensing module 22
and outputs control signal to control the lamp control module 24
only when the illumination detection module 21 outputs the turning
on signal. However, when the illumination detection module 21
outputs the tuning off signal, the signal processing module 23 will
immediately output control signal to the lamp control module 24 so
as to control all of the LED lamps 10 to work in the closed mode.
It can be understood that it is possible to use a plurality of the
sensing control devices 20 in some commercial lighting or large
room of home lighting. When a plurality of sensing control devices
20 are provided, the respective sensing control devices 20 should
be independent and non-interference with each other. However, any
one of the plurality of sensing control devices 20 can control the
work state of all of the plurality of LED lamps 10. That is to say,
as long as one of the plurality of sensing control devices 20
output control signal, it is possible to control all of the LED
lamps 10 in the automatic sensing system 100 to work under one of
the three operation modes. In the present embodiment, only one
sensing control device 20 as an example is presented to illustrate
the operation of the present invention.
[0013] Each of the sensing control devices 20 may further include a
power supply module 25. The power supply module 25 is used to
provide power for the entire sensing control devices 20 so that the
sensing control devices 20 has energy to run. Each of the sensing
control devices 20 may further include a wireless output module 26
which outputs a wireless signal based on the control signal of the
lamp control module 24. The LED lamps 10 may also include a
wireless receiving module 11 which receives the wireless signal
output from the wireless output module 26 and controls the working
state of the LED lamp 10. The wireless signal may be a WIFI signal
or a Bluetooth signal. Moreover, the sensing control device 20 may
also transmit the control signal via a wire.
[0014] As described above, the automatic sensing system for LED
lighting 100 control the operation mode of the LED lamps 10
according to the brightness level of the current environment and
whether or not someone is in the environment. Moreover, only when
the current brightness level of the environment need to turn on the
lights, the sensing control device 20 will be to detect whether
someone is in the current environment. As a result, it can achieve
the purpose of automatic sensing and energy saving.

least one sensing control device 20 electrically connected to the
at least one LED lamp 10, the sensing control device 20 includes an

the human body in the current environment; [0018] S103: the
illumination detecting module 22 detects the brightness of the
current environment and provides a control signal; [0019] S104:

module 22 senses the infrared rays radiated by the human body in
the current environment; [0020] S105: the signal processing module

[0021] S106: the lamp control module 24 controls all of the LED
lamps 10 to work under one of the three operating modes in

can control the operation of all of the LED lamps 10.
[0022] In step S103, the illumination detecting module 21 provides
different control signal in accordance with the brightness level of
the current environment. As described above, the brightness level
includes three stages. The brightness of the first stage is greater
than 200 lumens, the brightness of the second stage is less than
200 lumens and greater than 1 lumen, and the brightness level of
the third stage is less than 1 lumen. In the first stage, the
illumination detecting module 21 outputs a signal of stopping
working. In the second stage, the illumination detecting module 21

lamps 10 work in the closing mode according to the control signal
output from the signal processing module 23.
[0024] In step S105, when the brightness level of the current
environment is the second stage, the signal processing module 23
