Description

A kind of LED bulb lamp with radiator structure
Technical field
The utility model relates to technical field of lamps, is specifically related to a kind of LED bulb lamp with radiator structure.
Background technology
Use increasing today at led light source, the heat radiation that strengthens led light source is to improve light efficiency and the main development in life-span.The radiating mode that the LED ball bubble light source of selling on the market at present adopts all is that increasing heat radiation area is to reach the effect that strengthens heat radiation as much as possible, and this technology certainly will increase overall volume and the production cost of LED light fixture.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of simple in structure, production cost is low, the LED bulb lamp with radiator structure of good heat dissipation effect.
For achieving the above object, the utility model provides following technical scheme: a kind of LED bulb lamp with radiator structure, comprise lamp holder, lamp body and lampshade, described lamp holder is connected with lamp body one end, the described lamp body other end is connected with lampshade, be provided with cavity in the described lamp body, LED driving power and radiator are installed in the described cavity, described radiator is provided with the led light source plate near the lampshade end, be provided with radiator structure on the described lamp body, described radiator structure comprises air inlet and venthole, and described air inlet is arranged on the join domain of lamp body and radiator, the cavity mutual conduction in described air inlet and the lamp body.
By adopting technique scheme, because after the radiator in the ball bubble is heated by led light source, cause the air density reduction because of the rising of temperature in the ball bubble, thereby air is risen, discharge lamp body from venthole at last, the loss because of air in the lamp body cavity just replenishes from air inlet, thereby formed gettering effect, simple in structure, production cost is low, good heat dissipation effect.
The utility model further is set to: described lamp body upper end is provided with groove, and lamp holder is installed in the groove, and described venthole arranges around the lamp holder outer surface.By this setting, structure arranges rationally, reliable operation.
The utility model also further is set to: the corresponding radiator in described lamp body middle part arranges a plurality of air inlets.By this setting, the air inlet position arranges rationally, good heat dissipation effect.
The utility model also further is set to: described lamp body inner surface is metal level, and described lamp body outer surface is plastic layer.By this setting, lamp body structure arranges rationally, and skin can be anti-electric for plastics, and security is good.
The utility model also further is set to: described led light source plate comprises aluminium base and several LED lamps that are fixedly mounted on the aluminium base, and described aluminium base is fixedly connected with radiator.By this setting, radiating effect is better.
The utility model has the advantages that: by the appropriate design to the utility model structure, the gettering effect by air inlet reduces the temperature in the bulb lamp, good heat dissipation effect, and production cost is low, and is simple in structure.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
