Wherein, evenly be provided with a plurality of heat radiation internal projection and a plurality of cross-ventilation mouth on described radiating block, the shape of described heat radiation internal projection and cross-ventilation mouth match.
Wherein, the bottom of described transparent glass cover is provided with connector loop, and the internal diameter size of described connector loop is identical with radiating block, and the external diameter size of described connector loop is identical with caulking groove.
Wherein, described lamp plate comprises pcb board and a plurality of LED lamp pearl be electrically connected to it, and described a plurality of LED lamp pearls are installed on pcb board, and the exiting surface of described a plurality of LED lamp pearls is all towards transparent glass cover.
The beneficial effects of the utility model are: compared with prior art, the stereo concave-convex formula LED lamp cooling structure that the utility model provides, the pcb board radiator is provided with recessed caulking groove and the radiating block of protrusion, strong due to the energy force rate plane formula of caulking groove bearing strength, therefore strengthened the intensity of this pcb board radiator, and the bottom of transparent glass cover is contained in caulking groove, the two forms the cavity of sealing transparent glass cover and pcb board radiator, make both junctions not there will be gap, the phenomenon of therefore effectively having avoided light to leak; The radiating block protruded combines and forms the heat radiation of stereo concave-convex formula with recessed caulking groove, makes the area of dissipation of this pcb board radiator increase, and has improved radiating effect.The utlity model has reasonable in design, sound construction, bright dipping is effective and the characteristics of good heat dissipation effect.
The accompanying drawing explanation
The explosive view that Fig. 1 is stereo concave-convex formula LED lamp cooling structure of the present utility model.
The main element symbol description is as follows:
1, transparent glass cover 2, lamp plate
3, pcb board radiator 11, connector loop
21, pcb board 22, LED lamp pearl
31, caulking groove 32, radiating block
321, heat radiation internal projection 322, cross-ventilation mouth
The specific embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1, the stereo concave-convex formula LED lamp cooling structure that the utility model provides, comprise transparent glass cover 1, lamp plate 2 and pcb board radiator 3, the radiating block 32 that pcb board radiator 3 is provided with recessed caulking groove 31 and protrudes, the bottom of transparent glass cover 1 is contained in caulking groove 31 and is connected to form the cavity of sealing with pcb board radiator 3, lamp plate 2 all is contained in this cavity with radiating block 32, and lamp plate 2 is fixed on radiating block 32, caulking groove 31 is directly located direct punching press and is caved in and form in the periphery of traditional plane P CB plate radiator, do not increase material, therefore do not increase cost of manufacture, the recessed rear radiating block 32 of caulking groove 31 just forms convex shape relatively, the three-dimensional area of dissipation that improves this light fixture of this male and fomale(M&F), further improve radiating effect, therefore on light fixture without separately establishing radiating piece, greatly reduced the entire area of LED light fixture.
Situation compared to prior art, the stereo concave-convex formula LED lamp cooling structure that the utility model provides, the radiating block 32 that pcb board radiator 3 is provided with recessed caulking groove 31 and protrudes, strong due to the energy force rate plane formula of caulking groove 31 bearing strengths, therefore strengthened the intensity of this pcb board radiator 3, and the bottom of transparent glass cover 1 is contained in caulking groove 31, the cavity of transparent glass cover 1 and 3 the two the formation sealing of pcb board radiator, make both junctions not there will be gap, the phenomenon of therefore effectively having avoided light to leak; The radiating block 32 protruded combines and forms three-dimensional heat radiation with recessed caulking groove 31, makes the area of dissipation of this pcb board radiator 3 increase, and has improved radiating effect.The utlity model has reasonable in design, sound construction, bright dipping is effective and the characteristics of good heat dissipation effect.
