As shown in Fig. 1 and Fig. 2, the utility model output wiring harness is made of socket 3, three kinds of red, white and black wires 4, plastic seat 6 together, and one deck of black flannelette sponge 5 is pasted on the wire for protection. The plastic seat 6 is locked and connected through the terminal crimped on the wire 4; the socket 3 is connected to the wire through the process of welding first and then injection molding, and is welded to the PCB board 2 through the pin; when assembling, it is interlocked with the optical filter 1 Together; the filter 1 is not only used for collecting and filtering ambient light, but also serves as a shell to protect the PCB board 2, and plays a role in installation and positioning; the PCB board 2 integrates a detection control circuit to realize all functions of the utility model.

As shown in Figure 3, the detection and control circuit of an embodiment of the utility model is composed of a voltage stabilizing circuit, a detection circuit, an arithmetic circuit, a driving circuit and an adjustable circuit. The DC 12V of the vehicle power supply is stabilized by the diode D1, the resistor R8, the capacitor C2, and the voltage regulator ZD1, and is provided to the detection circuit (photosensitive element PD, resistor R2), and the calculation circuit (resistors R1, R3, R4, R5, R6 , Capacitors C1, C3, C4, operation integrated module IC) and drive circuit (resistors R7, R9) voltage, adjustable circuit RW is used to set the opening and closing point voltage, and realize the adjustment of the operation coefficient.

When the ambient light intensity changes from strong to weak to lower than Lon, the photoelectric current of the photoelectric conversion becomes smaller, the voltage of pin 2 of the integrated computing module IC becomes lower, pin 1 of the IC outputs a light-on signal, and the power supply of the headlight and taillight of the car is connected. On, the light is on; when the ambient light intensity changes from weak to strong to higher than Loff, the photoelectric conversion photoelectric current becomes larger, the voltage of pin 2 of IC becomes higher, pin 1 of IC outputs the signal of turning off the light, and the power supply of the car's headlights and tail lights Disconnect, light off. When the ambient light intensity changes between Lon and Loff, the output remains unchanged. The light intensity setting Lon and Loff at the on and off points can be adjusted through the adjustable circuit RW. When the RW coefficient value becomes larger, the light intensity at the on and off points becomes higher. On the contrary, the RW coefficient value becomes higher. Hours, the light intensity at the on and off points becomes lower.

The utility model is installed on the dashboard of the automobile, below the windshield, and is convenient for detecting the ambient light intensity where the vehicle is located. When the ignition switch of the car is in the ACC gear or ON gear, the ambient light sensor will be powered on and in the on state. If the environment of the vehicle changes (such as passing through a tunnel or the light intensity changes), the ambient light sensor will sense the light through its own filter. The received light intensity is used to control the switch signal at the output end, and then automatically turn on or off the headlights and taillights of the car. When the ambient light intensity becomes weaker, the output terminal changes from the light-off signal to the light-on signal, and the headlights and tail lights of the car are automatically turned on. When the ambient light intensity becomes stronger, the output terminal changes from the light-on signal to the light-off signal. The headlights and taillights are automatically turned off.
