High-radiating-performance LED streetlamp

Abstract

The invention provides a high-radiating-performance LED streetlamp comprising a lamp shell and a streetlamp post connecting body which are fixed with each other. The lamp shell comprises more than one main radiating face and more than one auxiliary radiating face, the main radiating faces and the auxiliary radiating faces are all connected to a radiating substrate arranged inside the lamp shell and closely fitted with an LED wafer panel in a thermally-conductive manner, radiating fins are processed on the main radiating faces, a metal net frame is covered on the auxiliary radiating faces, and a sponge body is arranged in the metal net frame, and contacts with the auxiliary radiating faces after the sponge body absorbs water. The high-radiating-performance LED streetlamp is good in radiating effect, simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of road lighting equipment, in particular to an LED street lamp. Background technique [0002] As the current roads are getting wider and wider, the brightness requirements for street lights are getting higher and higher. Considering the issue of energy saving, LED street lights are being gradually promoted; and a problem encountered in the promotion process is that for high-brightness LED street lamps generate a huge amount of heat, and LED chips are highly sensitive to temperature. At high temperatures, the performance of LEDs will quickly decay. Therefore, for a small LED lamp, it is usually necessary to configure a huge heat sink. Therefore, the problem of heat dissipation is a major problem restricting the popularization of LED lighting devices. [0003] At present, the design of the heat dissipation structure of LED lighting mainly improves the heat dissipation effect by improving the shape and distribution o...

[0002] As the current roads are getting wider and wider, the brightness requirements for street lights are getting higher and higher. Considering the issue of energy saving, LED street lights are being gradually promoted; and a problem encountered in the promotion process is that for high-brightness LED street lamps generate a huge amount of heat, and LED chips are highly sensitive to temperature. At high temperatures, the performance of LEDs will quickly decay. Therefore, for a small LED lamp, it is usually necessary to configure a huge heat sink. device; therefore, the problem of heat dissipation is a major problem restricting the promotion of LED lighting devices

[0003] At present, the design of the heat dissipation structure of LED lighting mainly improves the heat dissipation effect by improving the shape and distribution of the heat dissipation fins, but no matter how it is changed, since the current heat dissipation fins are fixed, it can only rely on natural The way of heat dissipation is to dissipate heat to the outside, and its heat dissipation effect is extremely limited; and for some structures with higher requirements, a motor fan structure is configured to perform forced convection heat dissipation. In addition to the cost of the motor itself, it is also necessary to consider the waterproofing of the motor. The cost of the structure leads to a substantial increase in the cost of the heat sink, which is also not conducive to popularization and application
