Description

Technical Field

[0002] A lighting power supply is a device that provides electrical energy to various lighting equipment. Its core function is to convert, stabilize, and regulate the voltage and current of the input electrical energy (such as AC mains power or battery power) to meet the voltage, current, and other electrical parameter requirements of different lighting equipment, ensuring the stable and safe operation of the lighting equipment. In terms of application scenarios, lighting power supplies cover multiple fields, including homes, commercial spaces, industries, and outdoor applications. For example, a power supply for a table lamp in the home converts AC mains power into low-voltage DC power suitable for the lamp's operation; while the power supply for outdoor streetlights needs to adapt to complex outdoor environments, possessing waterproof and lightning protection capabilities, and may also integrate dimming and time control functions.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-4 The automatic dimming lighting power supply shown includes a lighting power supply body 1, with a placement groove on the surface of the lighting power supply body 1, and an adjustment mechanism 2 fixedly connected inside the placement groove.

[0031] The adjustment mechanism 2 includes a microcontroller 201 fixedly connected inside the placement slot. One side of the microcontroller 201 is electrically connected to a photoresistor 202 via a power line, and the other side of the microcontroller 201 is electrically connected to an LED lighting module 203 via a power line.

[0032] The surface of the lighting power supply body 1 is provided with a threaded hole, and a transparent protective cover 3 is connected to the internal thread of the threaded hole.

[0033] The transparent protective cover 3 facilitates the protection of the photoresistor 202.

[0034] The transparent protective cover 3 is disposed on the surface of the photoresistor 202, and the surface of the transparent protective cover 3 is threaded with positioning bolts 4.

[0035] The positioning bolt 4 facilitates the fixing of the transparent protective cover 3.

[0036] The top of the transparent protective cover 3 is threaded with heat dissipation fins 5, and the surface of the heat dissipation fins 5 is coated with a corrosion-resistant coating.

[0037] The heat dissipation fins 5 facilitate the improvement of heat dissipation performance of the lighting power supply body 1.

[0038] The lighting power supply body 1 has a heat dissipation hole on one side, and a cooling fan 6 is installed inside the heat dissipation hole.

[0039] The cooling fan 6 facilitates rapid heat dissipation from the main body 1 of the lighting power supply.

[0040] The lighting power supply body 1 has a wiring port 7 on one side, a connector 8 is inserted into the wiring port 7, and a plug 9 is electrically connected to one side of the connector 8 through a conductor.

[0043] 10 LED beads facilitate lighting.

[0044] Working principle: When this automatic dimming lighting power supply is in use, the photoresistor 202 detects the brightness of the environment. Based on the different brightness of the environment, the photosensitive module generates different output voltage signals to the microcontroller 201. According to the different voltage signals received from the photosensitive module, the microcontroller 201 generates different pulse width PWM signals. By adjusting the PWM pulse width, the conduction time of the low-voltage MOSFET is controlled, thereby controlling the output power of the LED driver power supply, and thus controlling and adjusting the brightness of the LED light-emitting module. Assuming that when the photosensitive module detects daytime brightness, it outputs a 5V voltage signal. When the microcontroller 201 receives the 5V voltage signal, it outputs a low-level PWM signal to turn off the LED lighting module 203. When the photosensitive module detects darkness at night, it does not output a voltage signal, and the microcontroller 201 does not receive a voltage signal. Therefore, the microcontroller 201 outputs a high-level signal, and the LED driver outputs maximum power. When the microcontroller 201 receives a 2.5V voltage signal, it outputs a 50% PWM signal, and the LED driver outputs half the power.
