[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] The utility model provides a light-controlled lamp control circuit, which is suitable for light-controlled control of various lamps. Figure 1 As shown, the light-controlled lighting control circuit includes a power module, an optical signal processing module, and a control output module. One end of the power module is connected to the live wire (LINE), the other end to the optical signal processing module, the other end to the control output module, and the other end to the neutral wire (NUTE). A lamp (DS1) is connected in series between the control output module and the power module. The optical signal processing module adopts an integrated design.

[0034] Specifically, the power supply is processed by the power module and then supplied to the optical signal processing module. When ambient light is low, the optical signal processing module outputs a high-level signal to the control output module. This turns on the power supply circuit of lamp DS1, illuminating it. When ambient light increases, the optical signal processing module outputs a low-level signal to the control output module. This turns off the power supply circuit of lamp DS1, extinguishing it.

[0035] The utility model provides a light-controlled lamp control circuit comprising a power supply module, an optical signal processing module, and a control output module. One end of the power supply module is connected to a live wire, the other end of the power supply module is connected to one end of the optical signal processing module, the other end of the optical signal processing module is connected to one end of the control output module, and the other end of the control output module is connected to a neutral wire. A lamp is connected in series between the control output module and the power supply module. The optical signal processing module employs an integrated design. By employing an integrated optical signal processing module and implementing optical signal processing using an integrated circuit, the structure of the light-controlled lamp control circuit is simplified and its anti-interference capability is improved. Furthermore, the simplified circuit structure and ingenious design align with the design concept of ultra-compact lamp controllers.

[0036] In an optional embodiment, as Figure 1 As shown, the optical signal processing module includes an integrated chip U1 and a voltage divider circuit. One end of the voltage divider circuit is connected to the other end of the power module, and the other end of the voltage divider circuit is connected to the first and second pins of the integrated chip U1, respectively. The fourteenth pin of the integrated chip U1 is connected to the other end of the power module, and the eleventh pin of the integrated chip U1 is connected to one end of the control output module.

[0037] Specifically, such as Figure 1 As shown, the voltage divider circuit includes: a first resistor R1, a second resistor R2, a third resistor R3, and a photoresistor GM1. One end of the first resistor R1 is connected to one end of the second resistor R2 and the other end of the power module, respectively. The other end of the first resistor R1 is connected to the other end of the second resistor R2, one end of the third resistor R3, the first pin 1 of the integrated chip U1, and the second pin 2 of the integrated chip U1, respectively. The other end of the third resistor R3 is connected to one end of the photoresistor GM1, and the other end of the photoresistor GM1 is grounded.

[0038] In this embodiment of the utility model, integrated chip U1 is CD4011BM. Furthermore, integrated chip U1 is comprised of four NAND gates: U1A, U1B, U1C, and U1D. Integrated chip U1 utilizes an integrated design, utilizing the CD4011BM integrated circuit to process optical signals. This simplifies the structure of the light-controlled lamp control circuit and improves its anti-interference capability.

[0039] Furthermore, the first resistor R1, the second resistor R2, the third resistor R3, and the photoresistor GM1 form a voltage divider circuit. When the ambient light is dim, the photoresistor GM1 is in a high-resistance state, the potential of the first pin 1 and the second pin 2 of the integrated chip U1 increases, and the eleventh pin 11 of the integrated chip U1 outputs a high-level signal to the control output module. The control output module controls the power supply circuit of the lamp DS1 to be turned on, and the lamp DS1 is lit. When the ambient light increases, the photoresistor GM1 is in a low-resistance state, the potential of the first pin 1 and the second pin 2 of the integrated chip U1 decreases, and the eleventh pin 11 of the integrated chip U1 outputs a low-level signal to the control output module. The control output module controls the power supply circuit of the lamp DS1 to be turned off, and the lamp DS1 is turned off.

[0040] In an optional embodiment, as Figure 1 As shown, the optical signal processing module further includes: a delay circuit, one end of which is connected to the fourth pin 4 of the integrated chip U1, and the other end of which is respectively connected to the eighth pin 8 and the ninth pin 9 of the integrated chip U1.

[0041] Specifically, such as Figure 1As shown, the delay circuit includes: a first diode D1, a first capacitor C1, and a fourth resistor R4. The anode of the first diode D1 is connected to the fourth pin 4 of the integrated chip U1, and the cathode of the first diode D1 is connected to one end of the first capacitor C1, one end of the fourth resistor R4, the eighth pin 8 of the integrated chip U1, and the ninth pin 9 of the integrated chip U1, respectively. The other end of the first capacitor C1 and the other end of the fourth resistor R4 are grounded.

[0042] In this embodiment of the present invention, when ambient light is low, the light-controlled lamp control circuit controls lamp DS1 to illuminate and simultaneously charges first capacitor C1. When ambient light increases, the potentials of pins 1 and 2 of integrated chip U1 drop. This causes first capacitor C1 to discharge, maintaining a high-level signal output from pin 11 of integrated chip U1. Once capacitor C1 has discharged, the lamp power supply circuit is shut off, turning off lamp DS1. The delayed off time of lamp DS1 is determined by the values of C2 and R3.

[0043] In an optional embodiment, as Figure 1 As shown, the control output module includes a rectifier circuit DB1 and a controllable switch T1. A first end of the rectifier circuit DB1 is connected to the live line (LINE) via the lamp DS1. A second end of the rectifier circuit DB1 is connected to the first end of the controllable switch T1. A third end of the rectifier circuit DB1 is connected to the neutral line (NUTE). A fourth end of the rectifier circuit DB1 is grounded. A controllable end of the controllable switch T1 is connected to the eleventh pin (11) of the integrated chip U1. A second end of the controllable switch T1 is grounded.

[0044] Specifically, such as Figure 1 As shown, when the ambient light is low, the eleventh pin 11 of the integrated chip U1 outputs a high-level signal, turning on the controllable switch T1, connecting the power supply circuit of the lamp DS1, and the power supply to the lamp DS1 through the rectifier circuit DB1. When the ambient low-level signal light increases, the eleventh pin 11 of the integrated chip U1 outputs a low-level signal, turning off the controllable switch T1, shutting off the power supply circuit of the lamp DS1, and preventing the power supply from supplying the lamp DS1 through the rectifier circuit DB1. In this embodiment of the utility model, the controllable switch T1 is a thyristor.

[0045] Because thyristors (SCRs) are low-power, high-power output devices, using them instead of relays in the control output module prevents arc damage to contacts and improves electrical life. Furthermore, the control output module uses a high-power rectifier circuit DB1, making the light-controlled lamp control circuit suitable for controlling a variety of lamps, such as tungsten filament bulbs, LED lamps, and energy-saving lamps.

[0046] In an optional embodiment, as Figure 1As shown, the power module includes: a second diode D2, a fifth resistor R5, a first voltage-stabilizing diode DZ1, and a second capacitor C2. The anode of the second diode D2 is connected to the live wire LINE, the cathode of the second diode D2 is connected to one end of the fifth resistor R5, and the other end of the fifth resistor R5 is connected to the cathode of the first voltage-stabilizing diode DZ1, one end of the second capacitor C2, one end of the first resistor R1, one end of the second resistor R2, and the fourteenth pin 14 of the integrated chip U1.

[0047] Specifically, the power supply supplies power to the integrated chip U1 after half-wave rectification by the second diode D2 , current limiting by the fifth resistor R5 , and voltage stabilization by the first voltage stabilizing diode DZ1 .
