Utility model content
The utility model, for the deficiencies in the prior art, proposes a kind of structure simple, and utilize small heat-dissipating device and heat conduction silicone oil to coordinate the heat radiation solving high-powered LED lamp, have the large merit LED light source utilizing silicone oil to dispel the heat in full light week, concrete technical scheme is as follows simultaneously:
A kind of high-power LED street lamp light source utilizing silicone oil to dispel the heat, be provided with lamp holder (1), base (2) is connected with in this lamp holder (1) lower end, this base (2) is provided with radiator (3), LED-baseplate (4) is had in the surface distributed of this radiator (3), described base (2) is also provided with lampshade (5), described radiator (3) and LED-baseplate (4) cover by this lampshade (5), and are filled with heat conduction silicone oil (6) at this lampshade (5).
In use, the heat that LED lamp bead in LED-baseplate (4) produces outwards is distributed by lampshade (5) after jointly being absorbed heat by radiator (3) and heat conduction silicone oil (6), wherein lampshade (5) is PC cover, and this PC cover is fixed on base (2) by bonding way.
For better realizing the utility model, can improve is:
Thermal vias (7) is provided with in the longitudinal direction of institute's radiator (3), and the cross section of this radiator (3) is regular pentagon, each side of this radiator (3) is all vertically arranged with radiating fin, this radiating fin is installed with described LED-baseplate (4).Radiator integral structure is simple, good heat dissipation effect, and wherein the setting of thermal vias can prevent radiator internal heat from gathering, also facilitate the immersion of heat conduction silicone oil simultaneously, better dispel the heat, adopt regular pentagon structure, evenly luminous, ensure 360 degree of luminescences of whole utility model.
The inner of described radiator (3) is provided with connecting plate (8), circuit board (9) is provided with in the outside of this connecting plate (8), the inner of each described LED-baseplate (4) all passes described connecting plate (8), is welded on described circuit board (9); In described base (2), be longitudinally inlaid with binding post, this binding post one end and described circuit board (9) are electrically connected, and the other end and described lamp holder (1) are electrically connected.The setting of circuit board can make whole utility model power circuit simple, compact conformation, and binding post and base adopt injection moulding integrated molding, ensure sealing, can prevent heat conduction silicone oil from flowing out.
Be connected by screw with base (2) at described lamp holder (1), structure is simple, and detachable maintaining is convenient.
Described lamp holder (1) is screwed socket, and better and existing lamp socket coordinates, and the convenient transformation to traditional illumination system, expands range of application of the present utility model.
The beneficial effects of the utility model are: overall structure is simple, compact in design, adopt the employing of heat conduction silicone oil, and while guarantee heat radiation, the body greatly reducing to have dispelled the heat is long-pending, reduces production cost, make the utility model can large-scale promotion; Adopt heat conduction silicone oil and radiator to coordinate, good heat dissipation effect, makes the utility model can be applicable to large merit lighting field, while guarantee light efficiency, extends the service life of LED.
