As everybody knows, lighting has obtained using widely in indoor and outdoor.Functions such as that existing lighting has usually is dustproof, waterproof, anti-corrosion, but its heat-sinking capability is relatively poor, particularly along with the appearance or the use of high-power LED light source and other power light source, existing lighting has been difficult to satisfy heat radiation and has required to carry out high light efficiency, long-life.For example high-power LED light source will produce a large amount of heats when luminous work, and untimely these heats that loose will have a strong impact on the light efficiency and the life-span of led light source.In fact, make lighting both have dustproof, water-proof function, having excellent heat sinking function has again become the technical problem that people press for solution.
Summary of the invention
The utility model is exactly to propose in view of the above problems, and its purpose is to provide a kind of dustproof, water-proof function that both had, and has the lighting of excellent heat sinking function again.
In order to achieve the above object, the utility model adopts following technical scheme: according to the utility model, a kind of high efficiency and heat radiation light fixture is characterized in that it comprises: metal base; The seal closure of printing opacity, the sealing cover is positioned at the below of described metal base, and with described metal base sealing and fixing; Metal cap with at least one ventilating opening, this metal cap is positioned at the top of described metal base, and fixes with described metal base; At least one heat-conducting piece is fixed on the upper surface of described metal base; A plurality of fin are fixed on the described heat-conducting piece; Light source is fixed on the lower surface of described metal base.
In order to strengthen its heat-sinking capability, at least one fan is set in the inside of described metal cap.Its fan can be fixed on the metal base, also can be fixed on the metal cap, also can be fixed on the heat-conducting piece, can also be fixed on the fin.
Metal base can adopt multiple shape, can be the metal base of a writing board shape, also can be the metal base of pot cover shape, can also be the metal base of other shape.
For the ease of the convection current of air, on described fin, air vent can be set.
For reduce metal base directly conduction give the heat of seal closure, to prevent the too high and quick aging of seal closure temperature, its seal closure can be by being provided with heat-insulating washer and described metal base sealing and fixing.
Described light source can be a led light source, also can be other light source.Described led light source can be fixed by the lower surface of heat-radiating substrate and described metal base.Described led light source can be the light source that one or more LED constitutes, and also can be the light source that one or more LED modules are constituted.
For the ease of converging light, a reflecting piece can be set below described metal base.
The utlity model has following good effect:
High efficiency and heat radiation light fixture of the present utility model, because seal closure and metal base sealing and fixing, its light source space of living in is an airtight space, thereby has dustproof, water-proof function.Metal base in the utility model, ventilative metal cap, heat-conducting piece and fin have constituted a heat abstractor efficiently, and the heat that is produced during light source works can be directly passed to this heat abstractor and loose, thereby have excellent heat sinking function.When heat load is very big, can also strengthen its heat loss through convection ability greatly by set fan.In addition, the utility model also has characteristics firm in structure, that the life-span is long.

The specific embodiment
Fig. 1 is the schematic diagram of high efficiency and heat radiation light fixture of the present utility model.As seen from the figure, the utility model comprises: the metal base 1 of writing board shape; Be positioned at the seal closure 2 of the printing opacity of metal base 1 below, the sealing cover around with the metal base sealing and fixing; Metal cap 3 with a plurality of ventilating openings 7 is positioned at the top of metal base 1, and its bottom is fixing with metal base 1; A flat column metal heat-conducting spare 4 is positioned at the top of metal base 1, fixedlys connected with the upper surface of metal base 1 in a side of this flat column metal heat-conducting spare; There is numerous phases fin 5 across a certain distance fixing with heat-conducting piece 4; Light source 6 is fixed on the lower surface of metal base 1, and the light source 6 here is a led light source.Find out easily that from figure metal base 1 and seal closure 2 have constituted an airtight space, and light source 6 is positioned at wherein, makes it have dustproof, water-proof function.Because metal cap 3 is directly fixing with metal base 1, the heat-conducting piece 4 that is fixed with numerous fin 5 is also directly fixing with metal base 1, metal base 1, metal cap 3, heat-conducting piece 4 and fin 5 have just constituted a high-efficiency radiator like this, and the heat that is produced during light source 6 work looses in ambient air with regard to being directly passed to this high-efficiency radiator.
Fig. 2 shows second embodiment of high efficiency and heat radiation light fixture of the present utility model.As seen from the figure, this high efficiency and heat radiation light fixture comprises: metal base 1; Be positioned at the seal closure 2 of the printing opacity of metal base 1 below, the sealing cover around with the metal base sealing and fixing; Metal cap 3 has a plurality of ventilating openings (not drawing among the figure), is positioned at the top of metal base 1, and its bottom is fixing with metal base 1; A metal heat-conducting spare 4 is fixed on the upper surface of metal base 1; There is numerous phases fin 5 across a certain distance fixing with this metal heat-conducting spare 4; Light source 6 is fixed on the lower surface of metal base 1.Can also see that from figure an end of the afterbody of this high efficiency and heat radiation light fixture and lamp stand 9 is fixed; A dividing plate 11 is set at the inside of metal cap 3, is used to be provided with power-supply controller of electric 8 so that be separated out a space.This is an embodiment who uses as road lighting.The heat that is produced during light source 6 work can be directly passed to the high-efficiency radiator that is made of metal base 1, metal cap 3, heat-conducting piece 4 and fin 5, the heat that this high-efficiency radiator is accepted partly directly looses in ambient air, and part is loose in environment on every side after passing to lamp stand 9 again.
