Description

Patio light cooling fin structure

This work is about a patio light, especially a heat dissipation fin structure that greatly increases the heat dissipation effect and has both horizontal and vertical heat dissipation effects.

Press, patio lights are mostly hung below the ceiling and are used for lighting fixtures in large-scale lighting environments such as industrial plants, warehouses, station halls, gas stations, hypermarkets, and underground parking lots. Because the height of the ceiling is much higher than that of ordinary homes Or offices, so if the household lighting equipment on the market is installed on the ceiling of these places, it may cause the problem of insufficient lighting brightness because the illumination distance is too far, so a patio light that can provide long-distance lighting must be used; patio lights usually Its power consumption is more than 400 watts. The type of lamps is generally mercury lamps (or some sodium lamps). With the evolution of technology, patio lights are replaced by light emitting diodes (LEDs) from traditional mercury lamps.

Due to the development of light-emitting diode (LED) technology, which has the characteristics of low energy consumption and long service life, LED has gradually become the mainstream of the future in the lighting market. However, the higher the power of the LED, the more waste heat is generated. However, the high temperature has a considerable negative impact on the life and luminous efficacy of the LED. Therefore, most of the LED lamps with higher power will be equipped with a heat dissipation structure to timely Dissipate heat. However, if the power consumption of the LED itself is high and the heat dissipation speed is not fast enough, the LED is still easily damaged.
