DETAILED DESCRIPTION

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] Please refer to Figure 1 , an intelligent lighting driving circuit with low standby power consumption, comprising a rectifier module, a constant voltage module, an LED driving module, a power consumption reduction module and a control module; the input end of the rectifier module is used to connect to a power supply; the output end of the rectifier module is respectively connected to the power input end of the constant voltage module, the power input end of the power consumption reduction module and the control output end of the control module; the power output end of the constant voltage module is connected to the power input end of the LED driving module; the output end of the power consumption reduction module is respectively connected to the power control end of the constant voltage module and the power control end of the LED driving module; the control input end of the power consumption reduction module is connected to the output end of the control module; the control module is used to output a control signal according to a control instruction.

[0027] From the above description, it can be seen that the beneficial effects of the utility model are: the electric energy is transmitted to the LED driving module by connecting the constant voltage module with the rectifier module, that is, the power supply ranges of the constant voltage module and the LED driving module overlap, and the same power supply circuit can be shared, so that the power consumption reduction module can be shared; at the same time, by connecting the output end of the power consumption reduction module to the power control end of the constant voltage module and the power control end of the LED driving module respectively, the power consumption reduction module can control the constant voltage module and the LED driving module at the same time, so as to achieve the effect of one way of controlling multiple ways by the power consumption reduction module. When the control module sends a standby command to the power consumption reduction module, the power consumption reduction module outputs a signal to cut off the power of the constant voltage module and the LED driving module at the same time, thereby reducing the standby power consumption of the circuit.

[0028] Furthermore, the power consumption reduction module includes a first transistor, a second transistor and a first resistor; the collector of the first transistor is connected to the output end of the rectifier module and one end of the first resistor, the emitter is respectively connected to the power control end of the constant voltage module and the power control end of the LED driving module, and the base is connected to the other end of the first resistor and the collector of the second transistor; the base of the second transistor is connected to the output end of the control module, and the emitter is grounded.

[0029] From the above description, it can be seen that the power consumption reduction module is composed of the first transistor, the second transistor and the first resistor, so that the base of the second transistor is turned on after receiving a high-level signal, and the base of the first transistor is grounded and then cut off, so that the first transistor cannot supply power to the constant voltage module and the LED driving module, so that physical power is cut off through the internal circuit in standby mode, which has the effect of reducing standby power consumption.

[0030] Furthermore, the power consumption reduction module also includes a first voltage stabilizing unit and a first capacitor; the negative electrode of the first voltage stabilizing unit is connected to the base of the second transistor; the emitter of the second transistor is connected to the positive electrode of the first voltage stabilizing unit; one end of the first capacitor is connected to the base of the first transistor, and the other end of the first capacitor is connected to the emitter of the second transistor.

[0031] From the above description, it can be seen that by setting the first voltage stabilizing unit between the base and the emitter of the second transistor, a stable voltage difference is formed between the base and the emitter of the second transistor, so that the second transistor can work stably and respond promptly after receiving the level signal.

[0032] Furthermore, the power consumption reduction module includes a third transistor, a fourth transistor and a second resistor; the emitter of the third transistor is connected to the output end of the rectifier module, the collector is respectively connected to the power control end of the constant voltage module and the power control end of the LED driving module, and the base is connected to one end of the second resistor; the collector of the fourth transistor is connected to the other end of the second resistor, the base is connected to the output end of the control module, and the emitter is grounded.

[0033] From the above description, it can be seen that the power consumption reduction module is composed of the third transistor, the fourth transistor and the second resistor, so that the base of the fourth transistor is cut off after receiving a low-level signal, so that the base of the third transistor is in a cut-off state even when the voltage is high, so that the third transistor cannot supply power to the constant voltage module and the LED driving module, so that the internal circuit can achieve physical power off in standby mode, thereby reducing the standby power consumption.

[0034] Furthermore, the power consumption reduction module also includes a second voltage stabilizing unit and a third voltage stabilizing unit; the negative electrode of the second voltage stabilizing unit is connected to the emitter of the third transistor, and the positive electrode of the second voltage stabilizing unit is connected to the base of the third transistor; the negative electrode of the third voltage stabilizing unit is connected to the base of the fourth transistor, and the positive electrode of the third voltage stabilizing unit is connected to the emitter of the fourth transistor.

[0035] From the above description, it can be seen that by setting a second voltage stabilizing unit between the base and emitter of the third transistor, and setting a third voltage stabilizing unit between the base and emitter of the fourth transistor, the third transistor and the fourth transistor can be ensured to work stably and respond in time after receiving the level signal.

[0036] Furthermore, it also includes a first diode and a second diode; the anode of the first diode is connected to the output end of the power reduction module, and the cathode of the first diode is connected to the power control end of the constant voltage module; the anode of the second diode is connected to the output end of the power reduction module, and the cathode of the second diode is connected to the power control end of the LED driving module.

[0037] It can be seen from the above description that by setting the first diode and the second diode to limit the current direction, it is possible to prevent the constant voltage module and the LED driving module from having an abnormal reverse power supply, thereby avoiding the abnormality from affecting the power consumption reduction module.

[0038] Furthermore, the control module includes a power supply unit and a control unit; the input end of the power supply unit is connected to the output end of the rectifier module; the output end of the power supply unit is connected to the power input end of the control unit; and the control output end of the control unit is connected to the control input end of the power reduction module.

[0039] It can be seen from the above description that the power output by the rectifier module is converted into the power required by the control unit through the power supply unit, so that the control unit can work stably.

[0040] Furthermore, the control unit also includes a signal control end; the signal control end of the control unit is connected to the signal control end of the LED driving module.

[0041] It can be seen from the above description that by connecting the signal control terminal of the control unit with the signal control terminal of the LED driving module, the dimming signal of the LED driving module can be turned off by the control unit, thereby further reducing the standby power consumption.

[0042] Furthermore, it comprises at least two groups of the LED driving modules; the power input terminals of the LED driving modules are respectively connected to the power output terminals of the constant voltage modules; the power input terminals of the LED driving modules are respectively connected to the output terminals of the power consumption reduction modules.

[0043] It can be seen from the above description that by providing multiple groups of LED driving modules, each group of LED driving modules is connected to the output end of the power consumption reduction module, so that the multiple groups of LED driving modules can be controlled simultaneously.

[0044] Furthermore, the LED driving module includes an RGB driving chip, a red light LED, a blue light LED and a green light LED; the RGB input end of the RGB driving chip is respectively connected to the cathode of the red light LED, the cathode of the blue light LED and the cathode of the green light LED; the power output end of the constant voltage module is respectively connected to the anode of the red light LED, the anode of the blue light LED and the anode of the green light LED.

[0045] From the above description, it can be seen that by using the RGB chip and coordinating with the red LED, the blue LED and the green LED, the circuit can produce a variety of different lighting effects.

[0050] Please refer to Figure 3 The control module 5 includes a power supply unit 51 and a control unit 52; the input end of the power supply unit 51 is connected to the output end of the rectifier module 1, and is used to provide 3.3V voltage power supply to the control unit 52; the output end of the power supply unit 51 is connected to the power input end of the control unit 52; the control output end of the control unit 52 is connected to the control input end of the power reduction module 4; an antenna is provided on the control unit 52 for receiving instructions from a control device such as a remote control to generate corresponding control signals; for example, control signals such as dimming, color adjustment, shutdown, and startup are generated by receiving instructions.

[0051] Please refer to Figure 4The power consumption reduction module 4 includes a third triode V3, a fourth triode V4 and a second resistor R2; the emitter of the third triode V3 is connected to the output end of the rectifier module 1, the collector is respectively connected to the power control end of the constant voltage module 2 and the power control end of the LED driving module 3, and the base is connected to one end of the second resistor R2; the collector of the fourth triode V4 is connected to the other end of the second resistor R2, the base is connected to the output end of the control module 5, and the emitter is grounded. At the same time, the power consumption reduction module 4 also includes a second voltage stabilizing unit DR2 and a third voltage stabilizing unit DR3; the cathode of the second voltage stabilizing unit DR2 is connected to the emitter of the third transistor V3, and the anode of the second voltage stabilizing unit DR2 is connected to the base of the third transistor V3; the cathode of the third voltage stabilizing unit DR3 is connected to the base of the fourth transistor V4, and the anode of the third voltage stabilizing unit DR3 is connected to the emitter of the fourth transistor V4; wherein, the second voltage stabilizing unit DR2 and the third voltage stabilizing unit DR3 are formed by connecting a diode in parallel with a resistor and a capacitor, for example, the second voltage stabilizing unit DR2 includes a diode, a resistor R16 and a capacitor C11; the third voltage stabilizing unit DR3 includes a diode and a resistor R21.

This method is suitable for the architecture where the constant voltage circuit is solid or floating.

[0052] In an optional embodiment, multiple groups of LED driver modules 3 are provided, and the power input end of each group of LED driver modules 3 is connected to the power output end of the constant voltage module 2, and the power input end of the LED driver module 3 is respectively connected to the output end of the power reduction module 4; that is, the control method in this example is applicable to a multi-level line solution (controlling the constant voltage module 2 and the LED driver module 3 at the same time), and is also applicable to a multi-line solution (controlling multiple LED driver modules 3 at the same time).

[0053] In this example, the constant voltage module 2 adopts the Boost circuit, the LED driving module 3 adopts the five-way linear scheme through I2C communication, the power supply adopts the resistor voltage reduction method, and the power reduction module 4 adopts the low level effective method to control the working principle of the above-mentioned low standby power consumption intelligent lighting driving circuit. The specific principle is as follows:

[0054] When the control module 5 receives the shutdown command (i.e., standby), it generates a standby control signal; the control unit 52 sends an I2C signal to the RGB driver chip IC3 by closing the SDA pin and the SCL pin. At the same time, the control unit 52 provides a low-level signal to the power reduction module 4 through the STB pin, that is, the base of the fourth transistor V4 is at a low level, and the fourth transistor V4 is cut off at this time; because the fourth transistor V4 is cut off, the third transistor V3 is also cut off; when the third transistor V3 is cut off, the HV end is turned off to power the constant voltage module 2 and the LED driver module 3. Among them, when the HV stops supplying power, the RGB driver chip IC3 cannot process the signal, but can still receive the I2C signal. Therefore, turning off the I2C signal can also avoid unnecessary energy consumption, so that except for the modules that need to monitor the status in real time, all other circuits are cut off from power supply, thereby achieving the lowest power consumption.

[0055] When the control module 5 receives the power-on command, it generates a high-level signal; at this time, the fourth transistor V4 is turned on, and the third transistor V3 is turned off, so the HV terminal can power the constant voltage module 2 and the LED driver module 3; at the same time, the recovery control unit 52 sends an I2C signal to the RGB driver chip IC3 through the SDA pin and the SCL pin.

[0056] Embodiment 2

[0057] Please refer to Figure 2 In an application scenario where a high level is used as a control signal, the power consumption reduction module 4 includes a first transistor V1, a second transistor V2, a first resistor R1, a first voltage stabilizing unit DR1 and a first capacitor C1; the collector of the first transistor V1 is connected to the output end (HV) of the rectifier module 1 and one end of the first resistor R1, the emitter is respectively connected to the power control end of the constant voltage module 2 and the power control end of the LED driving module 3, and the base is connected to the other end of the first resistor R1 and the collector of the second transistor V2; the base of the second transistor V2 is connected to the output end (STB) of the control module 5, and the emitter is grounded; the negative electrode of the first voltage stabilizing unit DR1 is connected to the base of the second transistor V2; the emitter of the second transistor V2 is connected to the positive electrode of the first voltage stabilizing unit DR1; one end of the first capacitor C1 is connected to the base of the first transistor V1, and the other end of the first capacitor C1 is connected to the emitter of the second transistor V2; the first voltage stabilizing unit DR1 includes a diode and a resistor R21. A resistor R14 and a resistor R20 are also provided to provide a stable power supply for the transistor.

[0058] The specific working principle of the power consumption reduction module 4 in this embodiment is as follows:

[0059] When the control module 5 receives the shutdown command, it generates a standby control signal; the control unit 52 provides a high-level signal to the power consumption reduction module 4 through the STB pin, that is, the base of the second transistor V2 is at a high level, and the second transistor V2 is turned on; since the second transistor V2 is turned on, the first transistor V1 is turned off; and after the first transistor V1 is turned off, the HV end will shut down the power supply to the constant voltage module 2 and the LED driving module 3, thereby achieving the lowest power consumption.

[0060] When the control module 5 receives the power-on command, it generates a low-level signal; at this time, the second transistor V2 is turned off, and the first transistor V1 is turned on, so the HV terminal can supply power to the constant voltage module 2 and the LED driver module 3. However, this method cannot work when the constant voltage circuit is a floating ground structure. The method of controlling with a low level in the first embodiment can be applied to the structure of the constant voltage circuit being a solid or floating ground.
