Description

A kind of micro heat pipe fin heat-dissipating LED ball bulb lamp

Technical field

The utility model relates to LED home lighting field, a kind of especially micro heat pipe fin heat-dissipating LED ball bulb lamp, and novel heat sinking function is applied to the bulb lamp lighting of home of the high-power integrated optical source of LED.

Background technology

Green energy conservation LED light source is the development trend of following illumination, but LED illumination application also exists a lot of technical bottlenecks, the particularly heat dissipation problem of high power LED integrated light source lighting directly to have influence on light decay and the life-span of LED.

Current LED light fixture is in the class developing rapidly, dispel the heat about LED, at present, the concentrated light fixture of the high-power integrated optical source heat of many LED is all also to adopt aluminium section bar, pottery waits aluminum radiator, because the high-power integrated optical source heat of LED is concentrated, single heat sink material or heat conduction are slow, slow with cross-ventilation, radiating effect is not good does not reach heat radiation requirement, and the mode of other good heat dissipation effect such as the combination of heat pipe and aluminium fin heat radiation be applied in lighting field particularly the application of lighting of home be not also extensive, main cause is the problem of heat pipe processing technology difficulty, also has structural design simultaneously, production technology is implemented also more difficult.

Summary of the invention

In view of above-mentioned heat pipe heat radiation effect is in the disappearance of the application of LED illuminating industry and technology, a kind of micro heat pipe fin heat-dissipating LED ball bulb lamp is provided, allow LED illumination come into popular life, life is more had good taste.

For reaching above-mentioned purpose, the utility model provides a kind of micro heat pipe fin heat-dissipating LED ball bulb lamp, includes: lampshade, high power LED integrated light source, micro heat pipe aluminium radiator, base, power supply, lamp holder; High power LED integrated light source is fastened on micro heat pipe aluminium radiator and fits tightly connection; Power supply is contained in the bottom space of base and lamp holder.

1, above-mentioned a kind of micro heat pipe fin heat-dissipating LED ball bulb lamp, micro heat pipe aluminium radiator is with micro heat pipe heat conduction, for liquid-circulating heat conduction fast, be transmitted to the aluminium radiating fin being closely connected with micro heat pipe, and dissipation of heat is formed to convection current with air in air, the heat that high-power LED integrated optical source is produced is taken away, the combination radiator of micro heat pipe and aluminium fin, and overall heat conduction is fast and radiating effect is good.

2, above-mentioned a kind of micro heat pipe fin heat-dissipating LED ball bulb lamp, micro heat pipe circulation cooling is that main micro heat pipe is the heat pipe that diameter is less than or equal to 4mm, shell adopts metal tube, inwall attaches mesh-like liquid-sucking core, to utilize capillary force to make hydraulic fluid not restriction of heat pipe position and moving in liquid-sucking core.Shut at shell two ends, shuts frontly first will in pipe, to vacuumize, and pours into appropriate working solution.

Above-mentioned a kind of micro heat pipe fin heat-dissipating LED ball bulb lamp, employing be high power LED integrated light source, light is even, production technology assembling is easy.
