Problems solved by technology

[0004] At present, there are generally two types of heat sinks for LED lamps. One is an integrated heat sink that is directly die-cast. This heat sink has thicker fins and weaker heat dissipation due to the production process.
The other is to splice and assemble extruded metal thin-walled parts into a heat sink. This kind of heat sink has thinner fins and stronger heat dissipation capability. However, due to the deformation of metal thin-walled parts, it is easy to produce Poor contact leads to heat conduction failure in some positions

The heat dissipation device is characterized in that an outer cylinderand the inner cylinder are adhered and fixed to each other through an upper sealing ring and a lower sealing plate, mercury fills the space between the outer cylinder and the inner cylinder, and two heat dissipation positioning components are in butt joint and sleeve the exterior of the outer cylinder in a matched mode; a plurality of vertical notches I are formed in the cylinder wall of the outercylinder, the middles of a plurality of high-heat-conduction rectangular metal sheets I are fixedly and hermetically adhered to the interiors of the corresponding vertical notches I, the inner end ofeach high-heat-conduction rectangular metal sheet I extend into the position between the outer cylinder and the inner cylinder, and the outer end of each high-heat-conduction rectangular metal sheetI is provided with a plurality of heat dissipation fins in an inserted mode; a lamp holder is fixedly adhered to the inside of the inner cylinder, a plurality of vertical notches II are formed in thewall of the inner cylinder, the middles of a plurality of high-heat-conduction rectangular metal sheets II are fixedly and hermetically adhered to the interiors of the corresponding vertical notches II, the outer end of each high-heat-conduction rectangular metal sheet II extend into the position between the outer cylinder and the inner cylinder, and the inner end of each high-heat-conduction rectangular metal sheet II is tightly attached to the lamp holder. According to the heat dissipation device, the heat conduction transition is carried out through the mercury, and the heat dissipation isstable and efficient.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp cooling device and an LED lamp. Background technique [0002] In the field of lighting, LED lamps have basically replaced traditional tungsten lamps due to their advantages of energy saving, environmental protection and relatively long service life compared with traditional tungsten lamps. [0003] As we all know, LED lights will generate a lot of heat when they are used, especially high-power LED lights. If the heat generated cannot be discharged in time, it will affect the lighting effect of the LED lights and even shorten the service life. Therefore, the LED light cooling device role is particularly important. [0004] At present, there are generally two types of heat sinks for LED lamps. One is an integrated heat sink that is directly die-cast. This heat sink has thicker fins and weaker heat dissipation due to the production process. The other is to splice and assemb...
