Background technology
It is to substitute conventional incandescent and electricity-saving lamp as purpose that LED is applied on the light source series products as emerging lighting engineering.Most of LED light source product is not really reaching the requirement of replacing conventional light source aspect the technical parameters such as optic angle degree and luminous flux on the market, and therefore, this product technology research and development purpose is to allow product can really reach the requirement of replacement.Most of LED light source product can classify as with Types Below on the market: the first, product the first half are the luminous component of chip assembly and the translucent lampshade of PC, and the latter half is thermal component (generally adopting car aluminum component and die casting aluminum component) and the lamp holder of whole product; The second, product adopt the spherical glass lamp globe, and the lampshade center is that the lampshade lower part is aluminium radiation and lamp holder by the high-power paster of certain order straight cutting LED; The third, product adopts globe holder (material can be PC, glass), and lampshade internal illumination device is the form of direct insertion LED maize rod, and the lampshade lower part is aluminium radiation and lamp holder by plastic casing wrapped.All there is following problem in most of LED light source product aspect heat radiation and light efficiency: one, the product radiator structure is unreasonable causes that the drive circuit life-span is too short and the chip light decay is too early, thereby affects the product life cycle.Two, chip position design is unreasonable, causes the light angle too small, and the product application facet fails to realize replacement conventional incandescent and electricity-saving lamp truly.Three, too much bare metal radiating piece causes product in use to have the potential safety hazards such as hot and easy electric shock.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of LED radiator structure, and it improves the radiating efficiency of LED light source by modular radiator structure design, increases product optic angle degree, more than the actual measurement angle reaches 330 degree.
the utility model solves above-mentioned technical problem by following technical proposals: the LED radiator structure, it is characterized in that, it comprises translucent milky lampshade, four fin, the LED wafer, aluminum alloy die casting, screw, protective sleeve, drive circuit board, lamp holder, fin, the LED wafer, aluminum alloy die casting, screw all is positioned at translucent milky lampshade, aluminum alloy die casting is between fin and LED wafer, angle between LED wafer and horizontal plane is 75 degree, be screwed between protective sleeve and aluminum alloy die casting, protective sleeve wraps the upper part of drive circuit board, lamp holder is fixed on the below of drive circuit board, directly do not contact between four fin and be independent radiating module, a breach is left on the top of aluminum alloy die casting.
Preferably, the upper end of described protective sleeve is provided with cable hole, and the lower end of protective sleeve is provided with air-vent.
Preferably, the shape of the shape of the shape of described translucent milky lampshade, aluminum alloy die casting, fin is all petal-shaped.
Preferably, there is the LED wafer placement area in described aluminum alloy die casting front, and a breach is left, the below of translucent milky lampshade and fin formation space in LED wafer placement area top.
Preferably, the width of described fin reduces from the bottom to the top successively.
Positive progressive effect of the present utility model is: the utility model is by modular radiator structure design, the radiating efficiency of light source is more increased, product optic angle degree more strengthens, more than the actual measurement angle reaches 330 degree, and luminous softer, there are the problems such as light leak, shadow in elimination, is dispelled the heat too much and affects the life cycle that extends product thereby intercept simultaneously effectively power drives.Lampshade and the design of fin petal type, the more intimate hommizations such as anti-scald protection against electric shock protection.

Fig. 1 is the planar structure schematic diagram of the utility model LED light source structure.
Fig. 2 is the perspective view of the utility model LED light source structure.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
as depicted in figs. 1 and 2, the utility model LED light source structure comprises translucent milky lampshade 1, four fin 2, LED wafer 3, aluminum alloy die casting 4, screw 5, protective sleeve 6, drive circuit board 7, lamp holder 8, cable hole 9, air-vent 10, fin 2, LED wafer 3, aluminum alloy die casting 4, screw 5 all is positioned at translucent milky lampshade 1, LED wafer 3 is positioned on the front of aluminum alloy die casting 4, fin 2 is positioned at aluminum alloy die casting 4, angle between LED wafer 3 and horizontal plane is 75 degree, fixing by screw 5 between protective sleeve 6 and aluminum alloy die casting 4, protective sleeve 6 wraps the upper part of drive circuit board 7, lamp holder 8 is fixed on the below of drive circuit board 7, the upper end of protective sleeve 6 is provided with cable hole 9, the lower end of protective sleeve 6 is provided with air-vent 10, a breach 11 is left on the top of aluminum alloy die casting 4.
Angle between LED wafer and horizontal plane is 75 degree, and the optic angle degree theoretical value of integral LED light source product reaches 330 ° like this, and measured value solves the problem of existing product light angle too small more than 330 °.
Aluminum alloy die casting also can dispel the heat; the shape of the shape of translucent milky lampshade, the shape of aluminum alloy die casting, fin is all petal-shaped; every aluminum alloy die casting is defined as an independent radiating module, and drive circuit board is by protective sleeve parcel protection empty in column type.There is the LED wafer placement area in the front of aluminum alloy die casting, and the top of aluminum alloy die casting (top of LED wafer placement area) leaves a breach, the below of translucent milky lampshade and fin form certain space, form certain cross-ventilation by following space and top breach and dredge heat radiation.Every fin is independent radiating module, the width of fin reduces from the bottom to the top successively, due to product after assembling is completed, not directly contact between every independent fin, effectively intercept the heat radiation impact between the LED wafer, and the heat that the heat radiation transmittance process of independent radiating module is the generation of LED wafer is delivered to aluminum alloy die casting by thermal grease, thereby aluminum alloy die casting contacts dissipation of heat in air by air.Greatly reduce the contact area of fin and drive circuit board due to the utility model, and protective sleeve leaves air-vent, greatly reduce so the suffered heat effects of drive circuit board is compared existing product, thereby further extend life-span of drive circuit board.Cable hole conveniently carries out the cabling of electric wire.Modular Structure Design has solved existing product radiator heat undue concentration, and the heat accumulation impact between the LED wafer is dredged better heat and distributed in an orderly manner, drives the protection design and reduces radiator heat to the impact of drive circuit board.In the globe-type luminescence zone, the metalwork that product external surfaces does not directly expose, the following part of translucent milky lampshade is also effectively blocked the sheet metal that exposes when guaranteeing heat dissipation ventilation, thereby forms certain anti-scald protection and electrocution-proof protection.
Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
