LED safety street lamp

Abstract

The invention provides a novel LED safety street lamp having a passive heat dissipation function of a high-power LED lamp wick and applied to the field of LED illumination. The alternating-current 36V safety voltage is output from the front end of a power supply cabinet to achieve power supply of the LED safety street lamp, and the LED safety street lamp and the power supply cabinet are provided with intelligent controllers controlling switching and luminance. Each LED street lamp post head is re-designed and made of high-heat-conductivity metal, a double-layer water tank is manufactured and is separated by a partition plate from the middle, the upper layer and the lower layer are communicated through a partition plate water opening, the water opening is sealed by a plug, the upper-layer water tank is opened and used for collecting rainwater, and the lower-layer water tank is filled with water. The water tank cannot be completely full of the water in a place where the temperature is not higher than zero DEG C, a space for ice expansion is reserved, the water tank can be completely full of the water in a place where the temperature is higher than zero DEG C, the lamp post heads are located at the position of the bottom of the lower-layer water tank, a lamp arm is connected with a lamp holder, the LED lamp wick is installed on the lamp holder, the lamp arm is hollow for power line laying. Accordingly, by adopting the design, the heat dissipation problem of the high-power LED lamp wick is solved.

Description

technical field [0001] The invention is a new type of LED safety street lamp, which has a passive heat dissipation function of a high-power LED wick and is applied in the field of LED lighting. Background technique [0002] China is a big producer and consumer of incandescent lamps. In 2010, the output and domestic sales of incandescent lamps were 3.85 billion and 1.07 billion respectively; All lamps are replaced with energy-saving lamps, which can save 48 billion kwh of electricity annually, which is equivalent to reducing carbon dioxide emissions by 48 million tons. There is a huge potential for energy saving and emission reduction; The structure of the lighting appliance industry will be upgraded and optimized, and it will also achieve the "Twelfth Five-Year Plan" energy-saving and emission reduction goals and contribute to the response to global climate change. [0003] LED lighting has begun to replace incandescent lamps on a large scale, and LED street lamps have also...

Problems solved by technology

[0003] LED lighting has begun to replace incandescent lamps on a large scale, and LED street lamps have also begun to replace incandescent lamps, entering the streets and alleys of every city, but LED street lamps have a series of problems due to overheating of wicks, such as brightness attenuation, shortened life, and even chip burnout. , the aluminum substrate currently used can no longer meet the heat dissipation requirements of high-power LED street lamps, and the power supply planning of the entire LED street lamp can no longer meet the requirements of new technology development. How to solve the problem of heat balance of LED wicks and how to optimize the power supply layout of LED street lamps is The more urgent and difficult problems facing the development of LED lighting industry
