Abstract
The utility model relates to a kind of graphite radiating LED ball bulb, a kind of graphite radiating LED ball bulb, comprise lamp socket, plastic casing, LED light source, lamp housing be in turn connected into one, radiator is equipped with at the described LED light source back side, and described radiator is separated by arrange by graphite heat and aluminium radiator and is formed.The utility model perfect heat-dissipating, and the spotlight effect producing different color irradiates ground, has illumination and color spotlight effect, is suitable for market sales counter and uses.
Description
Technical field
The utility model belongs to bulb, is specifically related to a kind of graphite radiating LED ball bulb.
Background technology
Because LED has high brightness, the effect such as energy-conservation, use more and more in various occasion, but because the caloric value of LED light source is larger, normal needs heat radiation ensures that it normally works, existing LED light source, when carrying out heat dissipation design, generally arranges fin after LED light source, is dispelled the heat by fin, due on LED heat conduction to fin mainly through heat loss through radiation, thus radiating effect is poor.
In the passive heat dissipation technology of existing LED lamp, major part is abundant not to the utilization of the free convection of heat, or does not form good path on the direction of thermal convection current, thus has influence on radiating effect.Traditional LED radiator, LED radiator as described in China Patent Publication No. 102661594A, although make use of the principle of air heats rising convection current, but its light source is placed in the bottom of radiator, an aperture is only stayed to carry out thermal convection current heat radiation, therefore the path of thermal convection current heat radiation is little, radiating effect is poor, radiator existence is heated uneven, the two ends temperature difference is large, the problem that utilization rate is low, the fin of this radiator is placed in the outside of radiator body simultaneously, have impact on outward appearance on the one hand, the fin being placed in outside on the other hand easily piles up dust, affect the radiating effect of radiator.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of graphite radiating LED ball bulb, this LED ball bulb good heat dissipation effect, has illumination and color spotlight effect.
The technical solution of the utility model is: a kind of graphite radiating LED ball bulb, comprise lamp socket, plastic casing, LED light source, lamp housing be in turn connected into one, radiator is equipped with at the described LED light source back side, and described radiator is separated by arrange by graphite heat and aluminium radiator and is formed.
Described lamp housing outer wall is provided with ruddiness condenser and blue light condenser.
Described lamp socket is provided with hot gas row mouth.
Described plastic casing is provided with cross-ventilation hole.
Compared with prior art, the utility model has the following advantages:
Graphite radiating LED ball bulb of the present utility model, perfect heat-dissipating, adopts ruddiness condenser and blue light condenser, and the spotlight effect producing different color irradiates ground, has illumination and color spotlight effect, is suitable for market sales counter and uses.
Graphite radiating film is a kind of brand-new heat conduction and heat radiation material, has unique grain orientation, along both direction uniform heat conduction, laminar structuredly can adapt to any surface well, improves the performance of consumer electronics product while shielding thermal source and assembly.Heat isolation is also provided while product Homogeneouslly-radiating in thickness.The heat radiation of graphite heat-conducting fin solution uniqueness and heat-proof quality combination allow conductive graphite become the outstanding Material selec-tion of thermal management solutions.Super-high heat-conductive performance in conductive graphite plate plane within the scope of tool 150-1500W/m-K.
Carbon (C) element that the chemical composition of heat conductivity graphite material is mainly single, a kind of native element metal mineral. film macromolecular compound can graphitization film under HTHP to chemically, because carbon is nonmetalloid, but but there is the conduction of metal material, heat conductivility, also there is the plasticity as the organic plastics, and also have special hot property, chemical stability, lubrication and can be coated in the surface of solids etc. some good processing performances, therefore, conductive graphite is at electronics, communication, illumination, many fields such as aviation and defence and military are obtained for applies widely.
Graphite radiating film feature advantage:
1. splendid heat conductivility: thermal conductivity factor is up to 600-1200w/ (m-k) (be equivalent to 2 to 4 times of copper, aluminium 3 to 6 times), and thermal resistance is lower than aluminium by 40%, lower than copper by 20%.
2. light specific gravity: 1.0-1.9g/cm3 (density is equivalent to 1/4 to 1/10 of copper, 1/1.3 to 1/3 of aluminium).
3. low thermal resistance, soft and easily cut (can alternating bending).
4. surface can with other combinations of materials such as metal, plastic cement, adhesive stickers to meet more design function and needs.
Accompanying drawing explanation
Fig. 1 is the utility model graphite radiating LED ball bulb STRUCTURE DECOMPOSITION schematic diagram.
Fig. 2 is the structural representation of the utility model graphite radiating LED ball bulb.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1-2, a kind of graphite radiating LED ball bulb, comprise for the lamp socket 5 of screw socket 6, plastic casing 3, LED light source 1, lamp housing 4 are in turn connected into one, radiator is equipped with at described LED light source 1 back side, and described radiator is separated by arrange by graphite heat 2 and aluminium radiator 11 and is formed.
Described lamp housing 4 outer wall is provided with ruddiness condenser 9 and blue light condenser 10.
Described lamp socket 5 is provided with hot gas row mouth 8.
Described plastic casing 3 is provided with cross-ventilation hole 7.
This LED ball bulb adopts graphite heat 2 to combine with aluminium radiator 11, setting of being separated by, as: graphite heat-aluminium radiator-graphite heat-aluminium radiator, because graphite heat absorbs heat different from aluminium radiator, can exchange fast " convection current ", increase radiating effect
Lamp housing 4 outer wall is provided with ruddiness condenser 9 and blue light condenser 10, ruddiness condenser 9 and blue light condenser 10, the spotlight effect producing different color irradiates ground, makes this LED ball bulb have illumination and color spotlight effect, is suitable for market sales counter and uses.
LED light source 1 embeds in plastic casing 3, and lamp socket 5 is arranged on the top of plastic casing 3, and lamp housing 4 is arranged on the lower surface of plastic casing 3, and plastic casing 3 is provided with cross-ventilation hole 7.Lamp socket 5 is provided with hot gas row mouth 8.
During use, cold air enters from cross-ventilation hole 7, inside plastic casing 3, form cross-ventilation, through the effect of graphite heat 2 with aluminium radiator 11, hot-air is discharged from hot gas row mouth 8.
Below be only the preferred embodiment of the present invention, it should be pointed out that above-mentioned preferred embodiment should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim limited range.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
