Technical field
The utility model belongs to lighting field, relates to a kind of shot-light, is specifically related to a kind of GU10 shot-light take LED as light source.
Background technology
Common GU10 shot-light, comprise bulb socket, LED light source, LED driving power, optical lens and the aluminum shell for dispelling the heat, described LED light source, LED driving power and optical lens are placed in the accommodation space of described bulb socket and described aluminum shell composition.LED light source generally adopts several LED lamps to realize, and described LED driving power adopts Switching Power Supply power supply, and described aluminum shell is bowl-shape, and optical lens is fixed on the big opening end of aluminum shell, and optical lens is glass structure.Described LED light source is fixed on the inside of aluminum shell by aluminum base circuit board, between LED light source and aluminum base circuit board, be welded and fixed.
In said structure, bulb socket, aluminum shell divide and are arranged, and have increased making and the processing technology of whole shot-light; Meanwhile, the inner structure for fixing circuit board of existing aluminum shell is a plane, and heat dispersion is not good.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of novel GU10 shot-light, make its lamp holder and plastic casing one-body molded, thereby reduce making and the processing technology of whole GU10 shot-light; And its aluminium radiating piece is improved, increase area of dissipation, improve heat dispersion.
In order to solve the problems of the technologies described above, a kind of GU10 shot-light of the present utility model, comprise lamp holder, plastic casing, LED light source, circuit board, LED lamp plate, aluminium radiating piece and upper cover, wherein, lamp holder and plastic casing are one-body molded, and circuit board is set in plastic casing, set gradually aluminium radiating piece, LED lamp plate and upper cover on plastic casing, LED light source is located on LED lamp plate, circuit board and the electrical connection of LED lamp plate.
Further, described aluminium radiating piece has the bottom (so that aluminium radiating piece is positioned in plastic casing) matching with the profile of plastic casing, upwards extend this bottom makes whole aluminium radiating piece form frustum cone structure, wherein, the bottom of this aluminium radiating piece has a boss, and LED lamp plate is located on this boss.By this boss is set, increase the area of dissipation of aluminium radiating piece, improve radiating efficiency.In addition, the shape of boss and the setting of diameter, can determine according to the concrete distribution situation of the LED light source on LED lamp plate.The setting of the height of boss, can determine according to the angle of lens.
Further, interference fit between described aluminium radiating piece and plastic casing.
Further, described upper cover comprises cover plate and trim ring, and cover plate is provided with snap fit, and trim ring is provided with the snap ring coordinating with snap fit.
The utility model is by said structure, and compared with prior art, its lamp holder and plastic casing are one-body molded, have reduced making and the processing technology of whole GU10 shot-light; The setting of the boss structure of the bottom by aluminium radiating piece, has increased the area of dissipation of aluminium radiating piece, has improved heat dispersion; Interference fit between aluminium radiating piece and plastic casing, leads the heat on aluminium radiating piece on plastic casing simultaneously, further improves heat dispersion, and makes whole body seal performance good simultaneously, and extraneous dust is not easy to enter, and is not easy destroyed.
