LED outdoor lamp

Abstract

The invention relates to the field of lighting, in particular to an LED outdoor lamp. The LED outdoor lamp comprises a shell and a light generation unit. The light generation unit comprises a plurality of radiators and substrates installed on the radiators. LED lamp beads are installed on the substrate in a packaged mode. The shell comprises an arc cover and an installation base arranged in the arc cover. The installation base is in a grating shape, and the radiators are fixed to the installation base. Each radiator comprises a radiator body, a plurality of radiating holes formed in the radiator body and a deformation part connected with the radiator body, wherein the radiator body is of a hollow structure; the inner wall of the radiator body is provided with convex strips for installation of the corresponding substrate; and the deformation part is matched with the radiating holes and made of a shape memory alloy material. The LED outdoor lamp has the advantages of being compact in structure, dustproof, dampproof, good in radiating effect, stable in lighting and long in service life.

Description

technical field [0001] The invention relates to the lighting field, in particular to an outdoor LED lamp. Background technique [0002] LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy. [0003] LED lights have the advantages of long life, high light efficiency, low power consumption, anti-vibration, short response time, and no pollution. As an energy-saving point light source product, its application is more and more widely; with the advancement of technology, its color changes It is also becoming more and more abundant, so that it can be used not only as a decorative light source, but also for lighting. The existing LED lights for lighting generally have low power and are suitable for lighting places with small spaces. For places with large spaces such as roads, bridges, stadiums, ...

AI Technical Summary

Problems solved by technology

However, traditional radiators are generally closed cylindrical, which makes the air inside the radiator unable to circulate with the outside air in time, resulting in low heat dissipation efficiency, resulting in excessively high temperature of the LED light source and power supply, thus affecting the light efficiency of the LED. and lifespan

Although some radiators also have heat dissipation holes, in order to prevent dust and moisture for LED lights, the heat dissipation holes are small, resulting in problems such as insufficient heat dissipation, which will also affect the service life of LED lights
