Description

Technical Field

[0001] This utility model relates to the field of lighting control systems, and in particular to a gate control system for an energy-saving lamp. Background Technology

[0002] In existing lighting fixtures, a predetermined electronic control system is usually set up to achieve the function of saving electricity, so as to reduce energy consumption while meeting lighting needs. However, the existing lighting control system has a complex structure. When there are partial changes to the lighting fixture or product, the adaptability of the control system will decrease, which will affect its popularization.

[0003] For example, Chinese patent 202323376499.X has a complex control system structure and a high design cost. Utility Model Content

[0004] The main purpose of this invention is to propose a gate control system for energy-saving lamps, which aims to improve existing gate control systems and make the control system simple and stable, so as to meet the needs of daily use.

[0005] To achieve the above objectives, this utility model proposes a gate control system for energy-saving lamps, comprising:

[0006] The power supply includes a DC positive terminal and a DC negative terminal;

[0007] The LED lamp is connected in series between the DC positive and negative terminals, and a resistor R2 and a MOSFET Q1 are connected in series between the negative terminal and the LED lamp.

[0008] A voltage regulator module, one end of which is connected to the positive terminal of a DC power supply.

[0009] Control chip U2, the second pin VCC terminal of which is connected to the Vout terminal of the voltage regulator module.

[0010] A photodiode CDS is used to send external light signals to the control chip U2 and control the state of the LED. Resistors R3 and R6 are connected in parallel between the output terminal of the voltage regulator module and the control chip U2. The other end of the resistor R6 is connected in series with the photodiode CDS. The other end of the photodiode CDS is connected to the negative line. The photodiode CDS is used to send external light signals to the control chip U2 and control the state of the LED.

[0011] The infrared module includes an infrared receiving diode D1 and an infrared emitting diode D2.

[0012] The infrared receiving diode is connected in parallel with a capacitor C4. The other end of the infrared receiving diode D1 is connected to the positive terminal of the DC circuit, and the other end of the capacitor C4 is connected to the negative terminal.

[0013] The infrared receiving diode D1 and capacitor C4 are connected to pin 3 (CS) of the control chip U2.

[0014] The infrared module is used to detect human or object obstruction or displacement and send the signal to the control chip U2.

[0015] In practical design, a photoresistor is used to detect ambient light to avoid false activation during the day, and an active infrared diode is used to detect movement to achieve "lights turn on when people come", and finally the on / off state of the LED load or external load is controlled by driving the MOSFET (Q1).

[0016] When the ambient light level LUX exceeds a certain value, the control chip U2 enters standby mode.

[0017] When the ambient light level (LUX) is below a certain value, the control chip U2 activates its operating mode.

[0018] Infrared diode pair operating mode: The infrared diode is lit. When a person or object is detected blocking the light (door closed), the infrared receiving diode D1 receives the light signal from the infrared emitting diode D2, and there is no PWM output (light off).

[0019] When there is no person or object obstructing the view (the door is open), the receiving diode D1 does not receive the light signal from the infrared diode D2, and the PWM output goes high (the light is turned on).

[0020] This intelligent energy-saving circuit can be applied to practical applications of intelligent energy-saving door control, such as wardrobe doors, kitchen cabinet doors, drawer doors, refrigerator doors, disinfection cabinet doors, microwave oven doors, electric oven doors, and storage cabinet doors.

[0021] This achieves significant energy savings, while the capacitors (C1-C3) and numerous resistors (R1-R8) in the circuit ensure the stability of signal processing and the reliability of component operation. Attached Figure Description
