Description

technical field

The lighting source is arranged inside the lamp housing, and through the light-transmitting lampshade at the bottom of the lamp housing, it provides night lighting for the road and the surrounding environment. Street lamps have a wide lighting area and require high brightness, so most of them use high-power, large-size lighting sources, known as incandescent bulbs, mercury lamps and other light sources, but their lighting efficiency is poor, and the power consumption is serious. Light-emitting diodes (LED) came into being and has been widely used due to its high efficiency, energy saving and adjustable optical rotation.

However, regardless of the high-power, large-size lighting source, or the high-efficiency and energy-saving LED lighting source, the heat generated during its operation will continue to heat up during the working state, so the lamp group is at a higher temperature during operation. The environment, and its heat source mainly comes from the light source components, but the high temperature working environment will directly affect the life of various parts in the lamp group, and as the temperature rises, it will also cause the loss of light decay and decrease in brightness.

In order to solve the problem of high temperature, street lamps are used to dissipate heat. Metal lamp housings are used to improve the transfer of heat energy, thereby increasing the effect of heat energy spillage. The disadvantages of this method are that the metal lamp housings In order to be airtight, it is not easy to conduct heat energy to the metal lamp housing alone, let alone its heat dissipation effect.
