Compared with high-pressure sodium lamps, LED lamps have the advantages of low energy consumption, high brightness, fast response, long life, arbitrary dimming, wide color temperature range, high color rendering index and flexible intelligent control, making them the most ideal light source for road lighting. Widely concerned by the Chinese government. From "Ten Cities and Ten Thousand Cities" to "Fifty Cities and Two Millions", and then to the "Semiconductor Lighting Demonstration Project", it can be seen that LED street lighting has always been the focus of national policy support.
However, even if many advantages are in the body, there are policies that favor the promotion of LED street lighting. According to Changcheng Liangshun of Yanyaguang Power Plant, â€œAt present, there are more than 14 million street lamps installed in the country, of which only 530,000 LED street lamps account for 4% of the total installation of street lamps.â€ In addition to the lack of industry standards, high prices, and difficult maintenance, the biggest problem is that the LED street lamp cooling technology and the short board that really adapts to the harsh environment of roads in various regions are still not resolved, resulting in LED road lighting failure. Frequent power failures and dead lights are serious, which is not conducive to the scale of LED street lights. Therefore, solving the heat dissipation problem has become the premise of the promotion of LED street lamps.
Recently, Yanya Optoelectronics announced the launch of the first street lamp based on thermal magnetic radiator, which can effectively solve the heat dissipation problem of LED street lamps. Cheng Liangshun told Gaogong LED reporter, "Thermal radiator is a new type of radiator based on the new heat dissipation concept. It uses the characteristics that the polarity of the thermomagnetic material can be sequentially arranged in the thermal field environment, and forms a laterally moving thermal field on the surface of the radiator. Airflow to achieve the purpose of active heat dissipation."
The problem of heat dissipation is a disease in the street lamp industry
Simple processing technology with cost down
Patent application, preemptive
Modular design, optimistic about the future market
