Problems solved by technology
Because as a characteristic of the solid light source itself, the LED will also emit heat when it is working, and as the power of the LED continues to increase, the heat emitted by it will also increase significantly. Whether the heat emitted by it can be exported or dissipated in time has become a problem. The key factors that affect the quality and life of LED light, seriously affect its luminous brightness and service life
However, the existing heat dissipation devices used to dissipate heat from LED lamps have already faced bottleneck problems such as insufficient heat dissipation area, so that the heat dissipation performance cannot be further improved.

Embodiment Construction
[0013] Such as figure 1 and figure 2 As shown, the light emitting diode lamp includes a lamp socket 10 , a lamp cap 20 , a light emitting diode 30 , a circuit board 40 , a fixing frame 50 , a reflector 60 and a lampshade 70 .
[0014] Please also see image 3 and Figure 4 , the lamp holder 10 is made of aluminum or aluminum alloy, and can also be made of materials with high thermal conductivity such as copper and stainless steel. The lamp holder 10 includes a side wall 11 , the side wall 11 is generally in the shape of a truncated cone, and its outer diameter increases slightly from the lower end to the upper end. The upper end of the side wall 11 is open at the center, and a base 102 is formed at the center of the lower end to close the lower end of the side wall 11 , and its cross section is roughly U-shaped. The center of the base 102 slightly protrudes upwards to form a bump 107 , on which the LED 30 is installed. A depression (not shown) is formed on the bottom sur...

A light-emitting diode (LED) lamp is provided, which comprises at least one LED, a lamp holder for holding the LED lamp, and a circuit board arranged inside the lamp holder and eclectically connected with the LED. The lamp holder has a U-shaped cross section and comprises a base station and a side wall connected with the base station. The LED is arranged on the base station. The side wall of the lamp holder extends outwards to form a plurality of fins, each is forked from the outer surface of the side wall to form a plurality of branches. The outer surface of the lamp holder is provided thereon with the plurality of forked fins to efficiently increase the heat-radiating area of the lamp holder, so that the LED lamp has improved heat-radiating effect and prolonged service life.
Description
technical field [0001] The invention relates to a lamp, in particular to a light-emitting diode lamp with a heat dissipation device for heat dissipation. Background technique [0002] Light-emitting diodes (LEDs, Light-emitting Diodes), as light sources, are widely used in the fields of automobiles, traffic signal lights, screen displays, and even lighting due to their high-efficiency characteristics. As a lighting tool, compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. LED lamps are expected to replace tungsten lamps and mercury lamps in the 21st century, and become a new lighting source with both power saving and environmental protection concepts. [0003] With the development of application requirements, high-power LED lamps have many technical obstacles to overcome, especially in the heat dissipation of ultra-high-power LED lamps. Because as a characteristic of the solid light source itself, the LED will also e...
