Description
Technical field
The utility model relates to illumination articles for use, the LED ball shape bulb that particularly a kind of radiating efficiency is high.
Background technology
The LED ball shape bulb that radiating efficiency is high has been applied in every field with the characteristic of its high efficiency low power consuming.Usually, the LED ball shape bulb that radiating efficiency is high all needs to be configured with heat abstractor, be distributed to outside with the heat produced by LED ball shape bulb high for radiating efficiency thus reach the object improving the high LED ball shape bulb service life of radiating efficiency.At present in order to improve the high-cooling property of free convection, the fin that heat radiation uses is arranged on the high LED ball shape bulb shell of radiating efficiency, but its heatsink temperature is often up to 45 degree even more than 50 degree Celsius, such high temperature is positioned on the shell of bulb, easily causes the accident of scald when dismounting or the assembling of bulb.If this fin is arranged at bulb, or adopt the material of plastics to avoid scalding bulb shell, the heat that this bulb is come out cannot dissipate by only such mode, also cannot be produced the effect of cooling by the free convection of outside air, thus service life of LED lamp can be shortened because of heat dissipation problem.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, provides that a kind of structure is simple, good heat dissipation effect, the LED ball shape bulb that the wide radiating efficiency of illumination range is high.
For solving the problems referred to above of prior art, the technical scheme that the utility model provides is: the LED ball shape bulb that a kind of radiating efficiency is high, comprise lamp holder, plastic casing and hemispherical lampshade, the upper end-face edge of described plastic casing is provided with an annular rib, described annular rib is provided with a LED circuit board, a radiator is provided with in the middle part of the medial surface of described LED circuit board, the lateral surface of described LED circuit board is interval with multiple LED lamp bead, the outside spacers of described plastic casing is provided with polylith heat shield, between every two pieces of heat shields, there is a radiating groove, described plastic casing inner chamber is provided with a LED drive power, described LED drive power is electrically connected with described LED circuit board and described lamp holder respectively.
One as the high LED ball shape bulb of the utility model radiating efficiency is improved, and the upper end open place of described plastic casing has one and to be threaded mouth, described in the mouth that is threaded be threaded with described hemispherical lampshade.
One as the high LED ball shape bulb of the utility model radiating efficiency is improved, and the outside spacers of described radiator is provided with polylith fin.
Compared with prior art, the utility model has the advantages that: the utility model adopts plastic casing and radiator, the radiating groove of plastic casing is used for the heat diffusion of LED drive power, radiator is used for the heat diffusion of LED circuit board, the dismounting of the favourable bulb of the heat shield on plastic casing or assembling, prevent from scalding the accident caused.
