Description

LED cooling structure lamp body

technical field

The utility model relates to a structure for assisting LED lamp holders in heat dissipation.

Background technique

Because the brightness, power consumption, and service life of light-emitting diodes (LEDs) are far better than traditional light bulbs or mercury lamps and other light-emitting devices, they are widely used and replaced by traditional light-emitting devices, but their disadvantages are It will generate high heat, which will easily cause the LED body to have light decay or affect the service life. Therefore, how to assist the LED to conduct heat or dissipate heat is the key to the current application range.

Most of the existing heat dissipation structures are connected with a group of heat dissipation fins of the same shape and equidistant in the center of the heat source of the LED body, and after the heat generated by the LED is transferred through the heat dissipation fins, the flow of air is used to dissipate the heat to the heat source. However, the disadvantage of this heat dissipation structure is that it is bulky and difficult to assemble. In addition, the appearance and strength of the mechanism cannot be used as the surface material of the lamp. Therefore, if the heat dissipation facility is placed in a closed space inside the lamp, it is also Because it cannot contact with the outside air, it loses the function of heat dissipation. Furthermore, the efficiency of heat dissipation is directly proportional to the area of the heat dissipation structure, and heat conduction requires a considerable cross-sectional area, but within a certain distance and space. Therefore, the traditional heat dissipation structure cannot increase the area in a limited space, resulting in The cooling effect is limited.
