The invention provides a vacant type light-emitting diode (LED) power supply, and the vacant type LED power supply mainly solves the problems that the existing LED power supply is bad in heat dissipation performance and can not work in a high-temperature and high-moisture environment. The vacant type LED power supply comprises a circuit board, a power supply box body and a power supply box cover, the circuit board is fixedly arranged on the power supply box body, the power supply box body is in a U-shape or an L-shape and comprises a power supply box body side wall and a power supply box body base plate, and the circuit board is fixedly arranged on the base plate of the power supply box body; a vacant unit is independently and vertically arranged on the circuit board, and the working temperature of the vacant unit is -40 DEG C to 100 DEG C. Due to the adoption of the installation method of ejecting the vacant unit on the circuit board, the vacant unit can be independently changed, the vacant type LED power supply can be suitable for the high-temperature and high-moisture environment, an air duct is formed by vertically arranging the vacancy unit, heat can be easily taken through air flow circulation, and heat dissipation effect is further improved.
Description
technical field [0001] The invention relates to the field of LED lighting, in particular to a vacant LED power supply. Background technique [0002] Due to the advantages of environmental protection, long life and high photoelectric efficiency, LEDs have been rapidly developed in various industries in recent years, and the driving power of LEDs has become a focus of attention. In theory, the service life of LEDs is more than 100,000 hours, but in the actual application process Due to the improper design of the power supply and the selection of the driving method, the LED is easily damaged. [0003] The vacant unit of the existing LED power supply is generally arranged on the circuit board, which is not conducive to heat dissipation and is not suitable for normal operation in a high temperature and high humidity environment. SUMMARY OF THE INVENTION [0004] The invention provides an vacant LED power supply, which mainly solves the problem that the existing LED power suppl...
