Background technique

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.

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. Traditional LED lights have low heat dissipation efficiency, resulting in high temperature of the LED light source, which affects the light efficiency and life of the LED.

Contents of the invention

An inwardly extending connecting portion is provided at one end of the second connecting cylinder close to the base plate. The connecting part is fixedly connected with a motor, and the output shaft of the motor is connected with a fan blade. The motor is used to drive the fan blade to rotate. .

In one of the embodiments, the outer wall of the first connecting cylinder is connected with a plurality of second cooling fins.

In one of the embodiments, the first connecting cylinder is in the shape of a cylinder, the first cooling fins are in the shape of a straight plate, the first cooling fins are arranged in a circle along the end of the first connecting cylinder close to the substrate, the first cooling fins and the first connecting cylinder The radial direction of the radial direction forms an acute angle, and the direction of the first heat sink is parallel to the starting direction of the end of the air guide channel close to the connecting part.

In one of the embodiments, the first heat sink is arc-shaped.

In one of the embodiments, a second through hole is formed on the side wall of the first connecting cylinder away from the base plate.

In one of the embodiments, the connecting part is in the shape of a cone protruding toward the substrate, an opening is provided in the middle of the connecting part, and the motor is arranged in the opening and connected to the connecting part by screws.

The direction of the first cooling fin is parallel to the starting direction of the end of the air guide channel close to the connection part, which can facilitate the circulation of air. The arc shape of the first heat sink can not only further provide more heat dissipation area but also facilitate the circulation of air. The side wall of the first connecting cylinder away from the base plate is also provided with a second through hole to allow the air to escape from multiple directions, avoiding the situation that the air cannot escape when the first through hole at the end of the connecting plate is closed. The protruding conical shape of the connecting part can reduce the resistance of air circulation, and is beneficial to the air flow to the air duct.
