Problems solved by technology

However, the heat dissipation problem of LED lights is also a key issue, which seriously affects the light efficiency and life of LED light sources.
In traditional LED lamps, the base of the LED light source is generally closed and cylindrical, so that the air inside the base cannot communicate with the outside air in time, resulting in low heat dissipation efficiency, resulting in high temperature of the LED light source and power supply, which affects When it comes to the light efficiency and life of LED
Although some LED lamp bases now have heat dissipation holes, in order to prevent dust and moisture, the heat dissipation holes are small, resulting in problems such as insufficient heat dissipation, which will also affect the service life of LED lights

Abstract

The invention discloses an LED lamp which comprises a base plate, a control plate and a base, wherein LED lamp beads are integrally encapsulated on the surface of the base plate; the control plate is electrically connected with the LED lamp beads; the base is connected with the base plate; the base comprises a plurality of heat radiation holes and switch pieces matched with the heat radiation holes. The switch pieces are made of a shape memory alloy material and bend and deform to the direction far away from the heat radiation holes when being heated to a preset temperature. According to the LED lamp, the switch pieces can seal the heat radiation holes at normal temperature, and thus the base is in a sealed state. When the LED lamp is turned on, the switch pieces made of the shape memory alloy material can be heated to bend and deform to the direction far away from the heat radiation holes, so that the heat radiation holes can be opened, and the heat radiation efficiency is improved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp with a heat dissipation structure. 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 characteristics of energy saving and long life, avoiding the trouble of changing bulbs frequently, and are favored by more and more users. However, the heat dissipation problem of LED lights is also a key issue, which seriously affects the light efficiency and life of LED light sources. In traditional LED lamps, the base of the LED light source is generally closed and cylindrical, so that the air inside the base cannot communicate with the outside air in time, resulting in low heat dissipation efficiency, resulting in high temperature of the LED light so...
