Description
Technical field
The utility model relates to LED bulb technologies field, is specifically related to a kind of LED bulb with radiator structure.
Background technology
Along with the progress of expanding economy and society, the LED bulb has obtained extensive use.At present, led chip can only be converted into luminous energy with about 20% electric energy, and remaining 80% energy changes into heat energy, if it is bad that heat dissipation problem solves, heat concentrates in the small-sized chip, will make that the chip internal temperature is more and more higher, when the operating temperature of led chip reaches 55 degrees centigrade, life-span will reduce half, so the ultimate challenge that present LED bulb faces is heat radiation.
The LED bulb mainly is made up of lampshade, heat-dissipating casing, the led board etc. that is provided with led chip, produce heat during led chip work, major part is to pass to ambient air earlier by led board, and then by transfer of air to heat-dissipating casing, but because the air heat-transfer effect is poor, the heat that led chip is produced can not in time pass, and led chip burns out easily, has influenced the service life of LED bulb.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of LED bulb with radiator structure is provided, and the heat that produces in the time of led chip can being worked in time passes.
The utility model is realized by following technology.
A kind of LED bulb with radiator structure, comprise lamp holder, bulb socket, heat-dissipating casing, power supply, led board, lampshade, described lamp holder is fixed in described bulb socket, described bulb socket is connected with described heat-dissipating casing, described heat-dissipating casing forms ccontaining cavity, described ccontaining cavity is fixed with described power supply and described led board, described lampshade covers at described heat-dissipating casing, described power supply is electrically connected with led board and lamp holder respectively, described ccontaining cavity is provided with the heat radiation pallet, and described led board is fixed in described heat radiation pallet.
Described heat radiation pallet is arranged in the inwall of described heat-dissipating casing, and described heat-dissipating casing is the aluminum heat-dissipating casing, and described heat radiation pallet is copper heat radiation pallet.
The outer wall of described bulb socket is provided with dead ring.
