Problems solved by technology

The lifespan of the high-pressure sodium lamp light source circulating in the market today can reach 15,000-20,000 hours under the standard voltage working environment, but due to the large fluctuation of the working voltage relative to the standard voltage, the actual lifespan of the light source is less than 6,000 hours (about 1.5 years). , The average service life of the ballast is about 2.5-3 years, the service life is relatively short, and the installation and maintenance costs and operating power consumption costs of replacing the sodium lamp light source, ballast and other components are relatively high, which is not energy-saving enough

Embodiment Construction

[0005] The invention provides an LED street lamp, which includes an LED light source and a power supply. The power supply includes an input filter circuit, a rectification circuit, a high-frequency control circuit, an output rectification filter circuit and a detection control circuit. It is characterized in that the output terminal of the output rectification filter circuit is connected to the A constant current control circuit is connected between the detection and control circuits; a power factor adjustment circuit is connected between the output end of the rectification circuit and the high frequency control circuit.

[0006] The street lights on the side of the stadium are often the highest point of the stadium, so the camera effect for the game is the best. The inventor considers installing a game law enforcement platform on the LED street lamp, which can improve the accuracy of the instant playback and ensure the accuracy of the judgment while realizing the instant playb...

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED street lamp. Background technique [0002] At present, most of the street lights installed on the side of the stadium are high-pressure sodium lamps. The lifespan of the high-pressure sodium lamp light source circulating in the market today can reach 15,000-20,000 hours under the standard voltage working environment, but due to the large fluctuation of the working voltage relative to the standard voltage, the actual lifespan of the light source is less than 6,000 hours (about 1.5 years). , The average service life of the ballast is about 2.5-3 years, and the service life is relatively short, and the installation and maintenance costs and operating power consumption costs of replacing the sodium lamp light source, ballast and other components are relatively high, which is not energy-saving enough. Contents of the invention [0003] In order to solve the above problems, the present i...
