Abstract
The utility model discloses an LED bulb light with a heat radiation structure, which comprises the following components successively from top to bottom: a light holder, a heat radiation structure, an LED light source, and a transparent cover which covers the LED light source. The heat radiation structure is composed of a frustum-shaped heat radiator fixed with the light holder, and a heat radiation plate provided at the lower end of the heat radiator. A clearance is provided between the heat radiator and the heat radiation plate. Chambers are uniformly provided in the heat radiator. The side wall of the heat radiator is uniformly provided with heat radiation channels. An outward channel opening of each heat radiation channel is directly provided on the side wall surface of the heat radiator. The inner chambers of the heat radiator and the channels of the side wall are communicated with each other. According to the utility model, a principle of air convection is used for heat radiation. The increase of heat radiation area of the heat radiator is not required and an excellent effect of the heat radiation efficiency can be obtained. Simultaneously the production cost of the LED bulb light is reduced.
Description
Technical field
The utility model relates to technical field of lamps, refers in particular 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 the light efficiency and the main development in life-span.The LED ball bubble radiating mode of being sold on the market at present that light source adopted all is to increase area of dissipation as much as possible to reach the enhancing radiating effect.Certainly will increase the overall volume and the production cost of LED light fixture like this.
The utility model content
At above-mentioned technological deficiency, the technical problem that the utility model need solve provides that a kind of production cost is low, the LED bulb lamp of good heat dissipation effect.
The technical problem that the utility model need solve is achieved through the following technical solutions: a kind of LED bulb lamp with radiator structure, comprise lamp holder, radiator structure, led light source from top to bottom successively and cover the diffuser of led light source that described radiator structure is by forming with the truncated cone radiator of lamp holder locking and the heat sink of radiator lower end; Gapped between described radiator and the heat sink; The inside of radiator is evenly equipped with cavity, and the sidewall of radiator is evenly equipped with heat dissipation channel, and the outside passway of heat dissipation channel is directly arranged on the side wall surface of radiator, the passage mutual conduction of the cavity of radiator inside and sidewall.
Further: in above-mentioned LED bulb lamp with radiator structure, described radiator is locked on the lamp holder by screw.Described led light source is locked on the radiator by screw with heat sink.Described diffuser is bonded on the heat sink by silica gel.
Compared with prior art, above-mentioned LED bulb lamp with radiator structure, described radiator structure is by forming with the truncated cone radiator of lamp holder locking and the heat sink of radiator lower end; Gapped between described radiator and the heat sink; The inside of radiator is evenly equipped with cavity, and the sidewall of radiator is evenly equipped with heat dissipation channel, and the outside passway of heat dissipation channel is directly arranged on the side wall surface of radiator, the passage mutual conduction of the cavity of radiator inside and sidewall.In the time of the work of LED ball bubble, the heat that led light source produced looses by heat sink and radiator and goes to the outside, because radiator inside is distributed with a lot of cavitys, the temperature of cavity air also rises and the passway of the heat dissipation channel by the radiator sidewall sheds in the lump when radiator temperature rises, the air that temperature is lower then replenishes into cavity by the gap between heat sink and the radiator, thereby the formation stack effect makes that the heat radiation of radiator is faster.Thisly dispel the heat by cross-ventilated principle, do not need to increase the area of dissipation of radiator, its radiating efficiency just can reach splendid effect, has also saved the production cost of this LED bulb lamp simultaneously.
Description of drawings
Accompanying drawing 1 is the overall structure figure of the utility model LED bulb lamp;
Accompanying drawing 2 is explosive views of the utility model LED bulb lamp;
Accompanying drawing 3 is fundamental diagrams of the utility model LED bulb lamp;
Wherein, 1 lamp holder, 2LED light source, 3 diffusers, 4 radiators, 5 heat sinks, 6 gaps, 7 cavitys, 8 heat dissipation channels, 9 passwaies.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing:
As accompanying drawing 1-2, a kind of LED bulb lamp with radiator structure, comprise lamp holder 1, radiator structure, led light source 2 from top to bottom successively and cover the diffuser 3 of led light source 2 that described radiator structure is by forming with the truncated cone radiator 4 of lamp holder 1 locking and the heat sink 5 of radiator 4 lower ends; Between described radiator 4 and the heat sink 5 gapped 6; The inside of radiator 4 is evenly equipped with cavity 7, and the sidewall of radiator 4 is evenly equipped with heat dissipation channel 8, and the outside passway 9 of heat dissipation channel is directly arranged on the side wall surface of radiator, passage 8 mutual conduction of the cavity 7 of radiator inside and sidewall.Described radiator is locked on the lamp holder 1 by screw.Described led light source 2 is locked on the radiator 4 by screw with heat sink 5.Described diffuser 3 is bonded on the heat sink 5 by silica gel.
In the time of as the work of accompanying drawing 3:LED ball bubble, the heat that led light source 2 is produced looses by heat sink 5 and radiator 4 and goes to the outside, because radiator 4 inside are distributed with a lot of cavitys 7, when radiator 4 temperature rise, the temperature of cavity 7 air also rises in the lump and the passway 9 of the heat dissipation channel 8 by radiator 4 sidewalls sheds, the air that temperature is lower then replenishes into cavity 7 by the gap 6 between heat sink 5 and the radiator 4, thereby forms stack effect, makes that the heat radiation of radiator 4 is faster.Thisly dispel the heat by cross-ventilated principle, do not need to increase the area of dissipation of radiator, its radiating efficiency just can reach splendid effect, has also saved the production cost of this LED bulb lamp simultaneously.
The foregoing description only is a preferred implementation of the present utility model; in addition; the utility model can also have other implementations, and under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
