Description
Technical field
The utility model relates to a kind of LED light fixture, and particularly a kind of heat abstractor is hidden in the inner LED light fixture of lamp housing.
Background technology
Since the LED lighting emerges; Compare with traditional lighting; The LED lighting has advantages such as the color of energy-saving and environmental protection, high brightness, light is optional, the life-span is long; Therefore, the LED lighting just plays an increasingly important role at lighting field, and its product has replaced general incandescent lamp, electricity-saving lamp, fluorescent lamp.
But existing LED lighting general heating amount is all bigger, particularly some high-power LED lightings; Therefore, all be provided with heat abstractor on the existing LED lighting, heat abstractor adopts heat conduction good metal material to make; Volume is big, weight is big; In order better to dispel the heat, heat abstractor is arranged on outside the lamp housing, influences the outward appearance of LED lighting; Indivedual high-power LED lightings also need install electric fan additional and quicken heat radiation on heat abstractor, further increased the volume and the weight of LED lighting.
And in the process that the LED lighting is developing, deriving increasing light type gradually, the flat-type light source plate is the good example of one of them heat radiation.The flat-type light source plate is through a plurality of LED luminescence chips luminous purpose that reaches surface source luminescence simultaneously on planar substrates, thereby brings the inaccessiable illuminating effect of point light source light-emitting; Simultaneously, adopt integrated low-power LED luminescence chip energising illumination, can be spread heat at whole flat-type light source plate, the area of heat radiation is bigger, and the effect of heat radiation is better than spot light.But; Because it is the electrified light emitting zone of existing flat-type light source plate all is to be evenly distributed on fully on the substrate, therefore, big more the closer near the local brightness meeting the substrate center when work; And substrate middle part is compared with the periphery and will inevitably be concentrated more heat; And the heat of concentrating near the center in electrified light emitting zone more is just more, temperature is high more, during high-temperature operation for a long time, and as easy as rolling off a log the breaking down of LED luminescence chip in the electrified light emitting in centre zone; Thereby influence the operate as normal of whole flat-type light source plate, reduce the service life of flat-type light source plate.Simultaneously, existing flat-type light source plate also adopts external heat abstractor to dispel the heat, and volume is big, weight is big.
