Problems solved by technology

In order to resist acid, alkali and oxidation, some lamps are sprayed with paint on the shell of the lamp. As a result, the high heat of the LED is sealed and the heat cannot be dissipated, resulting in a shortened life of the LED lamp and a great loss of performance.

Embodiment Construction

[0033] The heat dissipation is stretched into a fin shape by aluminum profiles with high thermal conductivity (see picture), and the waterproof and dustproof shell is formed by die-cast aluminum (see picture). It consists of LED particles, an aluminum substrate, and a heat dissipation plate, and is called a luminous chamber (2), and its waterproof grade is IP65. The cooling chamber (1) is composed of power supply and heat dissipation fins, and its structure has air inlet (3) and air outlet (5), forming a convection heat dissipation system. In rainy days, rainwater can enter the heat sink groove directly from the air outlet , the direction of the cooling fin groove is designed to be at an elevation angle of 15° to the road surface (4), so the water in each cooling groove is concentrated into the plastic pipeline and discharged out of the lamp. The purpose of this technology is to prevent the water in the cooling chamber from entering the light emitting chamber. And affect the n...

Abstract

A technical invention that combines stretching and die-casting of aluminum materials to solve the heat dissipation and waterproofing of LED street lamps. It adopts a double-chamber structure, the upper chamber is made of die-cast aluminum to achieve waterproof and dustproof, and the lower chamber is stretched with aluminum to achieve the best heat dissipation effect. The upper and lower structures are integrated, which is both waterproof and dustproof and heat dissipation. The key technology invention is design Special structure aluminum reflector - LED is side-emitting, and the outgoing light is evenly projected to the 35-meter-long road through the reflector, and the heat dissipation effect and glare of side-emitting LED are better than traditional vertical light.

Description

1. Technical field [0001] It belongs to the technical field of semiconductor lighting and heat dissipation. 2. Background technology [0002] LED street lights have many advantages over traditional street lights, such as high luminous efficiency, high color rendering, long life, durability, low energy consumption, and better adaptability to low temperature environments, and LED lamps have the advantages of convenient regulation in terms of light color and intensity. Features and advantages, LED street lights have higher additional benefits, so they are optimistic by all parties that they will replace traditional lighting and become a new light source for future lighting. [0003] As the power of LEDs increases, the waste heat generated by LEDs increases relatively. If they cannot be effectively dissipated, the luminous efficiency of LED street lights will be seriously reduced. Often the installation is less than a year, and the light decay is serious. Therefore, the developm...
