What will be the impact of the increase in the internal temperature of chinese street light?|led street light wholesale|

July 08, 2022

After the led street light is used for a period of time, the internal temperature of the lamp will continue to rise during use. If the heat generated cannot be dissipated in time, it will have a great impact on the service life of led street light, and will seriously damage the led street light and the lamp holder.

The stability and quality of LED lamps are related to the heat dissipation of the lamp body itself. The heat dissipation of high-brightness LED lamps on the market mostly adopts natural plug-in radiators to dissipate heat, and the effect is not ideal.

LED lights with LED light sources are mainly composed of LEDs, heat dissipation structures, drivers, lenses, etc., so heat dissipation is also an important part of LED lights. If the LED does not dissipate heat well, its lifespan will also be affected. The heat dissipation methods of LED devices mainly include thermal conduction and thermal convection; the extremely low thermal conductivity of the substrate material leads to an increase in the thermal resistance of the device, resulting in a serious self-heating effect, which has a destructive impact on the performance and reliability of the device. The effect of heat on high brightness LEDs. Heat is concentrated in the small chip, and the chip temperature rises, resulting in uneven thermal stress distribution, and reduced chip luminous efficiency and phosphor laser efficiency; when the temperature exceeds a certain value, the equipment failure rate increases exponentially.

According to one study, reliability decreases by 10% for every 2°C increase in component temperature. In the LED lighting system composed of multiple LEDs in series and parallel, the heat dissipation problem has always been a concern of the industry. Solving thermal management issues has become a primary factor in high-brightness LED applications.
