A LED street lamp housing with the functions of using wind pressure, hot pressure to dissipate heat and self-cleaning

Abstract

The invention relates to an LED street lamp housing with the functions of utilizing wind pressure, hot pressure to dissipate heat and self-cleaning. The heat dissipation shell is composed of a heat dissipation base [2] with aluminum strips criss-crossing, a heat dissipation shell frame [1], and heat dissipation through holes [3] arranged on the heat dissipation base [2] and heat dissipation shell frame [1]. The LED pedestal [4] is directly combined with the grid-like heat dissipation matrix to maximize the heat dissipation area of ​​the high-power LED lamps. The heat dissipation shell can make the hot air rise along the gap between the aluminum strips, so as to achieve the purpose of convection and rapid heat dissipation of the air in a heat-pressing manner. The through holes on the frame of the heat dissipation shell and the base promote the flow of horizontal air. The heat dissipation shell can be completely in contact with the air, and the surface of the material is attached with a nano-coating, so that rainwater can be cleaned in the outer frame of the heat dissipation shell and the heat dissipation matrix, and has self-cleaning ability.

Description

technical field [0001] The patent of the present invention relates to a heat dissipation shell, in particular to a shell specially designed for effective heat dissipation of high-power LED street lamps. Background technique [0002] It is an ideal choice to use high-power LEDs as lighting devices. For LEDs, increasing the input power increases the brightness proportionally. During the working process, the efficiency of LED is far from 100%, and part of the energy is converted into heat, which is concentrated in a small chip, making the temperature inside the chip higher and higher, which will cause non-uniform distribution of thermal stress, Problems such as chip luminous efficiency and phosphor laser efficiency decline will directly affect the life of LEDs and increase the light decay of LEDs. Therefore, how to effectively improve the heat dissipation effect of high-power LED lamps has become one of the problems in the manufacturing process of lamps. Judging from most of ...
