Problems solved by technology

At present, the structure selected for the heat sink of the LED street light source is that on the back of a large aluminum plate, there are many heat sink-like structures vertically, which is a structure with the worst natural convection heat dissipation performance, resulting in a complex waterproof and moisture-proof structure for the LED chip. It is not suitable for power dissipation and rainproof, which increases the weight of the entire street lamp and increases the cost of construction, which is a serious problem for current LED street lamps.

Embodiment Construction

[0010] As shown in Figures 1 and 2 , the present invention is mainly composed of an integrated LED light source 1 , a secondary optical lens 2 , a deck 3 and a vapor chamber 4 .

[0011] In this example, the integrated LED light source 1 is composed of a plurality of LED chips 101 integrated on a package body 102 , and there are protrusions 1021 at both ends of the package body 102 . A large secondary optical lens 2 is installed on the integrated LED light source 1 . The secondary optical lens 2 includes a cross-section 201 composed of two semi-elliptical shapes and a slot 202 at both ends. The cross-section 201 is a light-transmitting body. The secondary optical lens is optically processed, preferably batwing light distribution. The card holder adopts an L-shaped structure, which can fix the integrated LED light source and the secondary optical lens, so that a tightly fixed optical part can be formed. At the same time, the back of the LED light source is directly installed ...

Abstract

The invention relates to an integrated LED road lamp optical system adopting a vapor chamber for heat dissipation. The integrated LED road lamp optical system mainly comprises an integrated LED light source, a secondary optical lens, a clamping seat and the vapor chamber, wherein the large secondary optical lens is adopted by the whole integrated LED light source which comprises multiple sets of integrated LED chips and a packaging body. The LED chips are integrated on the packaging body, the large secondary optical lens is used for achieving light distribution, and the optical lens achieves effective illumination and further can control dazzling through optical processing. The integrated LED road lamp optical system is simple in structure and good in illumination effect.

Description

technical field [0001] The invention relates to an integrated LED street lamp, in particular to an integrated LED street lamp optical system with a vapor chamber for heat dissipation. Background technique [0002] Due to the energy saving, long life and easy maintenance of LED lights, people have paid attention to LED technology in recent years, and LED lighting technology has been continuously developed. However, for high-power LED lights, one of the most critical issues is The heat dissipation problem of LED lighting. The quality of LED heat dissipation is very important to the whole lamp. If the heat cannot be dissipated, it will accelerate the aging of the chip, light decay, color shift, shorten the life of the LED, and reduce the light efficiency of the lamp. In other words, the problem of heat dissipation determines the life of lamps and lanterns, which seriously restricts the development of LED lighting. The temperature also affects the life of the LED itself, the hi...
