[0026] In the following, technical solutions in the embodiments of
the present application will be clearly and completely described
with reference to the drawings of the embodiments of the present
application. Obviously, the described embodiments are only a part
of the embodiments of the present application, but not all the
embodiments. Based on the embodiments of the present application,
all other embodiments obtained by a person of ordinary skill in the
art without creative efforts shall fall within the protection scope
of the present application.
Embodiment 1
[0027] FIG. 1 is a schematic diagram of a smart lighting control
device capable of reducing standby power consumption according to
an embodiment of the present application. As shown in FIG. 1, the
smart lighting control device capable of reducing standby power
consumption provided by the present application is used to control
a lamp 60, including a control module 10, a standby processing
module 30, a data transmission module 40 and a logic control module
50. The control module 10 is connected to the standby processing
module 30 and the data transmission module 40, the standby
processing module 30 is connected to the data transmission module
40 and the logic control module 50, and the data transmission
module 40 is connected to the logic control module 50.
[0028] Specifically, in this embodiment, the control module 10 is
configured to receive an external control instruction, convert the
external control instruction into a digital signal control
instruction, and send the digital signal control instruction to the
standby processing module and the data transmission module.
Further, the digital signal control instruction includes a flag bit
signal, a standby instruction bit, and grayscale data. The standby
processing module 30 controls turning on of the data transmission
module and the logic control module according to status of the flag
bit signal. When the flag bit signal is valid, the standby
processing module 30 sends an enable signal to the data
transmission module 40 and the logic control module 50, so that the
data transmission module receives the digital signal control
instructions from the control module 10. Then the logic control
module 50 sends a standby instruction signal to the standby
processing module 30 according to the standby instruction bit. When
the standby instruction bit is valid, the logic control module 50
sends a standby instruction to the standby processing module, and
the standby processing module controls the data transmission module
and the logic control module entering a standby state according to
the standby instruction. When the standby instruction bit is
invalid, the logic control module 50 controls operation of the lamp
60 according to the grayscale data.
[0029] Specifically, in this embodiment, the standby processing
module 30 is configured to send an enable signal to the data
transmission module and the logic control module according to the
digital signal control instruction. Further, as shown in FIG. 2,
the standby processing module 30 comprises a flag bit signal
processing unit 310, and the flag bit signal processing unit 310
comprises a first signal delayer 311, a comparator U313, and a
second signal delayer 312. An input terminal of the first signal
delayer and a second input terminal of the comparator are commonly
connected as an input terminal S1 of the flag bit signal processing
unit, to the control module 10. An output terminal of the first
signal delayer is connected to a first input terminal of the
comparator. An output terminal of the comparator serves as a first
output terminal S2 of the flag bit signal processing unit to output
a first delayed signal, and the output terminal of the comparator
is also connected to an input terminal of the second signal
delayer. An output terminal of the second signal delayer serves as
a second output terminal S3 of the flag bit signal processing unit
to output a second delayed signal.
[0030] Further, in this embodiment, FIG. 3 is a signal diagram of
the flag bit signal processing unit 310 of the standby processing
module 30 performing signal decomposition on the flag bit signal
input at the input terminal S1, wherein a pulse width represents a
signal that needs to be adjusted. As shown in FIG. 3, the flag bit
signal is delayed by the first signal delayer 311, and delay time
of the first signal delayer 311 is t1, then the delayed signal
reaches the first input terminal of the comparator U313 which is a
non-inverting input terminal of the comparator, and then compared
with a signal input from an inverting input terminal of the
comparator to obtain a first delayed signal. The first delayed
signal is delayed by the second signal delayer 312 to obtain a
second delay signal, and delay time of the second signal delayer
320 is t2.
[0031] Further, in this embodiment, FIG. 4 is a control signal
diagram input by the control module 10 to the data transmission
module 40, wherein duration time of various types of data needs to
be adjusted based on specific detection method of the data by the
logic control module 50 and the standby processing module 30. As
shown in FIG. 4, high-level duration of the flag bit needs to be
longer than the delay time t1 of the first signal delayer in the
flag bit signal processing unit 310, and the standby processing
module sends the enable signal to the data transmission module and
the logic control module. High-level duration of the data "0" code
should be shorter than a data sampling point time, high-level
duration of the data "1" code should be longer than the data
sampling point time, and the reset time duration should be longer
than a minimum reset signal sampling point time.
[0032] Specifically, in this embodiment, the data transmission
module 40 is configured to receive the digital signal control
instruction when the enable signal is received, and send the
sampled digital signal control instruction to the logic control
module.
[0033] Specifically, in this embodiment, the logic control module
50 is configured to control the lamp according to the sampled
digital signal control instruction, and is further configured to
send the standby instruction signal to the standby processing
module according to the sampled digital signal control
instruction.
[0034] Further, FIG. 5 is a circuit diagram showing a standby
instruction processing unit of the logic control module shown in
FIG. 1. The logic control module 50 comprises a standby instruction
processing unit 510, and the standby instruction processing unit
comprises a first MOS transistor M1, a first resistor R1, a second
MOS transistor M2, a second resistor R2, and a capacitor C, wherein
a gate of the first MOS transistor, a first terminal of the first
resistor, a first terminal of the capacitor and a drain of the
second MOS transistor are commonly connected as an input terminal
of the standby instruction processing unit, to the data
transmission module; a source of the first MOS transistor, a second
terminal of the first resistor and a second terminal of the
capacitor are commonly connected to a power supply VCC; the drain

resistor are commonly connected as an output terminal of the
standby instruction processing unit, to the standby processing
module; a second end of the second resistor is connected to a gate
of the second MOS transistor; a source of the second MOS transistor
is grounded. As shown in FIG. 6, in this embodiment, the standby
instruction data sampled by the data transmission module 40 is sent
to the S1 terminal. If there is no standby instruction signal, the
S2 terminal remains at a high-level. If the standby instruction
signal is sampled, the S2 terminal will remains at a low-level, and
the standby processing module will send a standby instruction.
[0035] Further, in this embodiment, the device further includes a
reset module 20, which is connected to the data transmission module
and the logic control module, and is configured to send a reset
signal to the data transmission module and the logic control module
when the power supply is turned on.
[0036] The smart lighting control device capable of reducing
standby power consumption provided by the present embodiment
receives a control instruction through a control module; and the
standby processing module sends an enable signal according to
status of a flag bit signal of the control instruction to a data
transmission module and a logic control module; and the data
transmission module receives the control instruction according to
the enable signal and transmits a sampled control instruction to
the logic control module; and when a standby instruction bit in the

standby instruction bit is valid, the logic control module sends a
standby instruction to the standby processing module; and the
standby processing module controls the data transmission module and
the logic control module to be turned off according to the standby
instruction, thereby standby power consumption of the lamp is
reduced.

module.
[0040] Step S2: It is detected whether the high-level duration of
the control signal is longer than t1, and if it is longer, the flow
advances to step S3, otherwise, the flow advances to step S4.
[0041] Specifically, in this embodiment, the control signal refers
to a flag bit signal in an external control instruction received by
the control module. When the chip is powered on, the control module
receives an external control instruction, converts the external
control instruction into a digital signal control instruction, and
sends the digital signal control instruction to the standby
processing module and the data transmission module. Further, the
time t1 refers to the delay time of the first signal delayer of the
flag bit signal processing unit of the standby processing
module.
[0042] Step S3: The data transmission module and the logic control
module are enabled.
[0043] Specifically, in this embodiment, when the high-level
duration of the flag bit of the digital signal control instruction
is longer than a preset time, the standby processing unit sends an
enable signal to the data transmission module and the logic control
module.
[0044] Step S4: Continue detecting signals.
[0045] Step S5: Determine whether the standby instruction bit is
valid. If it is valid, the flow advances to step S6; if it is
invalid, the flow advances to step S7.
[0046] Specifically, in this embodiment, upon receiving the enable
signal, the data transmission module receives the digital signal
control instruction, and sends the sampled digital signal control
instruction to the logic control module. The logic control module
determines whether the standby instruction bit of the sampled
digital signal control instruction is valid. When the standby
instruction bit is valid, the logic control module sends a standby
instruction signal to the standby processing module.
[0047] Step S6: The standby processing module disable the data
transmission module and the logic control module.
[0048] Step S7: The lamp is controlled according to the instruction
data and the grayscale data.
