The light cover is connected with the light body. The internal surface of the light cover is provided with a light-permeable heat conduction layer. The heat conduction layer is in contact with the light body. The internal surface of the light cover is provided with the heat conduction layer so that the heat dissipation effect of the light cover is enhanced.
Description
Technical field
The utility model relates to lighting field, relates in particular to a kind of LED bulb.
Background technology
LED illuminating product has the plurality of advantages such as environmental protection, energy-conservation, life-span be long, has and replaces gradually the trend that traditional incandescent lamp, fluorescent lamp become main illuminating product.But, owing to giving out a large amount of heats in the LED course of work, if the design of the radiator structure of LED illuminating product is unreasonable, can have a strong impact on its luminous efficiency and life-span.
The substrate of existing LED bulb lamp is placed on lampshade the inside, and the heat that LED distributes first hands down and is directed at radiator from substrate, is then dispersed in air.And the material of lampshade is generally optical-grade plastic or glass, its area is very large, but because the capacity of heat transmission of optical-grade plastic or glass is very poor, the effect that lampshade plays the heat radiation of whole LED bulb is very little.Particularly, because lampshade only has sub-fraction, follow lamp body to connect, because the heat conductivility of lampshade material is very poor, heat cannot be soon from the localized delivery connecting with lamp body to whole lampshade, and then distribute from whole lampshade, thereby the effect that lampshade plays the heat radiation of whole LED bulb is very little.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of LED bulb.
In order to solve above technical problem, LED bulb of the present utility model comprises LED light source, lamp body and lampshade, wherein, described LED light source is arranged on described lamp body, described lampshade is connected with described lamp body, and the inner surface of described lampshade is provided with the heat-conducting layer of printing opacity, and described heat-conducting layer contacts with described lamp body.
Preferably, described heat-conducting layer is arranged on the inner surface of described lampshade by the mode of spraying.
Preferably, the material of described heat-conducting layer is to take the composite that metal oxide is matrix material as heat filling, the transparent adhesive tape of take.
Preferably, described metal oxide is zinc oxide or tin oxide, and described matrix material is transparent silica gel.
Preferably, the thickness of described heat-conducting layer is 0.1 millimeter to 0.5 millimeter.
Preferably, the light transmittance of described heat-conducting layer is more than or equal to 90%.
Preferably, the thermal conductivity factor of described heat-conducting layer is 10 to 20W/m*K.
Preferably, described lamp body comprises radiator and lamp holder, and described LED light source is arranged on described radiator, and described heat-conducting layer is with described radiator contact, and described lamp holder connects with described radiator, in described radiator, is provided with driving power.
Preferably, the material of described radiator is metal or pottery.
Preferably, described lampshade is made by glass or plastics.
By the inner surface at described lampshade, heat-conducting layer is set, and make this heat-conducting layer with described lamp body contact, in the course of the work, the heat that described LED light source sends first conducts on described lamp body, then wherein a part is gone out from the heat sink radiates of described lamp body, and another part conducts to described lampshade and distributes through described lampshade through described heat-conducting layer.With prior art, compare, a heat radiation approach that LED bulb of the present utility model is many, has improved whole heat dispersion.By heat-conducting layer being arranged on to the inner surface of lampshade, lampshade can play a protective role to heat-conducting layer.By LED light source is arranged on lamp body, do not change the basic structure of LED bulb, can not make whole modulated structure complicated, can reduce design cost and processing cost.
