Description

Heat dissipation structure of lamps and lanterns

technical field

The utility model relates to a lamp structure, in particular to a lamp heat dissipation structure with heat dissipation effect.

Background technique

The structure of the conventional street lamp is that the bent extension end of the upright light pole is assembled with the lamp housing. 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. Conventional street lamps require high brightness, so most of them use high-power, large-size lighting sources, such as incandescent bulbs, mercury lamps and other illuminants, but the lighting efficiency is poor and the power consumption is serious. Light-emitting diodes (LEDs) rely on their high efficiency, Energy saving and tunable optical rotation came into being.

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, and its heat dissipation effect still needs to be improved and redesigned. This is the main problem to be solved by the utility model.
