FIFA LED stadium light smart system supplier in Bolivia
Summer is approaching and the temperature is rising. The led street light head is used for a long time after it is turned on in summer, and the temperature inside the led lamp will gradually rise. If the heat generated cannot be dissipated in time, it will have a great impact on the service life of the street lamp. , Seriously, it will damage the led street lamps and street lamp holders.
Like traditional light sources, LED light sources also generate heat during operation, and the amount depends on the overall luminous efficiency. Under the action of external electric energy, the radiative recombination of electrons and holes produces electroluminescence, and the light radiated near the PN junction needs to pass through the semiconductor medium and packaging medium of the chip itself to reach the outside world (air). Comprehensive current injection efficiency, radiative luminescence quantum efficiency, chip external light extraction efficiency, etc., in the end, only about 30-40% of the input electric energy is converted into light energy, and the remaining 60-70% of the energy is mainly generated by the lattice vibration of non-radiative recombination. Form into heat energy.
The stability and quality of LED lamps are very important to the heat dissipation of the lamp itself. The heat dissipation of high-brightness LED lamps on the market often uses natural fin radiators to dissipate heat, and the effect is not ideal.
The main structure of LED lamps using LED light source is composed of: LED, heat dissipation structure, driver, lens and other parts. Therefore, heat dissipation is also an important part. If the LED cannot dissipate heat well, its lifespan will also be affected. Thermal management is a major concern in high brightness LED applications.
Hishine’s LED street lights are all made of aviation-grade die-casting aluminum. In addition to being light in weight, it can also bring good heat dissipation to LED street lights.
