LED lamp

Abstract

The invention discloses an LED lamp, and belongs to the field of illumination. The LED lamp comprises LED light source components, a heat collection tube and a lampshade. The LED light source components are distributed on the heat collection tube in the axial direction of the heat collection tube. The heat collection tube is of a hollow structure and forms an air convection area. The air convection area is communicated with the outside world through openings in the top and the bottom of the heat collection tube. The lampshade wraps the LED light source components in the axial direction of the heat collection tube. The two ends of the lampshade form sealed ends at the two ends of the heat collection tube respectively so that a sealed light-emitting area can be formed in the lampshade. Through the structure, a better heat dissipation effect is achieved; the high-power LED light source components can be applied to the LED lamp while the side wall of the LED lamp emits light, and the requirements of a user are met. In addition, due to the sealing of the light-emitting area, vapor, dust, insects and outside objects can not enter the light-emitting area, and the normal work and safety performance of the LED lamp are ensured.

Description

technical field [0001] The invention relates to the field of lighting, in particular to an LED lamp. Background technique [0002] With the continuous improvement of people's living standards, the use of LED lights is becoming more and more popular. Most of the LED light sources of existing LED lamps are set downwards, so that the light from the LED light source will directly irradiate the user's eyes, forming light pollution, especially long-term irradiation will also cause dizziness and eye stinging of the user. On this basis, LED lamps with LED light sources arranged obliquely have appeared. In this way, a side-emitting LED light is formed, so that the light of the LED light source will not directly irradiate the user's eyes, and the light intensity and light pollution are effectively reduced. [0003] However, due to the inclined setting of multiple LED light sources, the light sources are scattered, and it is difficult to dissipate heat through a single radiator, whic...

AI Technical Summary

Problems solved by technology

[0003] However, due to the inclined setting of multiple LED light sources, the light sources are dispersed, and it is difficult to dissipate heat through a single radiator, which requires multiple radiators to be used together. On the one hand, the number of radiators is increased, thereby increasing production costs. ; On the other hand, the assembly process of each radiator is increased, which reduces the production efficiency

At the same time, due to the poor heat dissipation effect of the radiator, it is difficult to apply high-power LED light source to the LED lamp with the above structure, so it cannot meet the needs of users
