Problems solved by technology

However, since the radiator needs to communicate with the outside atmosphere for rapid heat dissipation, the radiator and the LEDs are not hermetically arranged in the lampshade. When the lamp is used outdoors, rainwater can easily flow through the radiator to the LEDs in rainy days, resulting in When the lamps are used in rainy days, there is a danger of leakage due to the ineffective waterproofing, which shortens the service life of the lamps and limits the scope of use of the lamps

Abstract

The invention relates to a light-emitting diode (LED) lamp comprising an LED module and a heat radiator for the LED module to patch as well as a shell. The shell comprises a top cover and a bottom cover fixed on the top cover; the heat radiator is contained and fixed in the bottom cover; a waterproof washer is clamped between the bottom cover and the heat radiator; and the LED module is sealed inthe shell by the heat radiator, the bottom cover and the top cover. Compared with the prior art, the LED module is fully sealed in a space enclosed by the top cover and the bottom cover, and the waterproof washer is clamped between the heat radiator and the bottom cover of the shell while the communication of the heat radiator and the exterior of the shell is ensured so that rainwater is prevented from flowing into the shell through the heat radiator, and the tightness of the LED lamp is effectively ensured.

Description

technical field [0001] The invention relates to a light-emitting diode lamp, in particular to a light-emitting diode lamp with a heat dissipation structure. Background technique [0002] As an efficient light source, light-emitting diodes have many characteristics such as environmental protection, high brightness, power saving, and long life, and have been widely used in various fields. However, the light-emitting diode lamps will generate heat when the light-emitting diodes are working, especially some high-power light-emitting diode lamps used for long-time lighting. If the heat is not dissipated in time, it is easy to overheat and damage the LED lamps. [0003] Usually, a heat sink is pasted on the surface of the light emitting diode of the lamp to dissipate heat, and then the light emitting diode and the heat sink are arranged in a lampshade. However, since the radiator needs to communicate with the outside atmosphere for rapid heat dissipation, the radiator and the LE...
