Technical field
The utility model is a kind of reflection shield of the LED of being used for lamp bar, belongs to the renovation technique of the used reflection shield of LED lamp bar.
Background technology
Along with the progress of LED lighting engineering, the proportion of LED lamp bar in illumination is increasing.LED lamp bar is progressively replacing fluorescent tube.But the reflection shield of LED lamp bar in the market is usually directly with the reflection shield of fluorescent tube, and the shortcoming of its existence is that Illumination Distribution is inhomogeneous, and the bright fringes of a plurality of parallel pipes that open the light can occur.
The utility model content
The purpose of the utility model is to consider the problems referred to above and provides a kind of Illumination Distribution even, and the reflection shield that is used for LED lamp bar of bright fringes phenomenon can not occur.The utility model can be realized the Illumination Distribution of approximate uniform rectangular hot spot, has very high uniformity of illuminance and utilization ratio of optical energy.
The technical scheme of the utility model is: the reflection shield that is used for LED lamp bar of the utility model, include the led light source that is electrically connected with the LED driving power, and wherein the outside of led light source is equiped with reflection shield.
The cross sectional shape of above-mentioned reflection shield is a dovetail groove, and the scope of dovetail groove base angle θ is: 10 degree are to 90 degree.
The inner surface of above-mentioned reflection shield is provided with optical coating.
The optical coating of above-mentioned reflection shield is tangerine peel coating or other casual anti-layers that looses.
The outer surface of above-mentioned reflection shield is provided with the heat radiation coating with heat loss through radiation function.
Above-mentioned reflection shield is the aluminium alloy reflection shield.
Above-mentioned led light source is the integrated led light source of module, or the led light source of the combination of many individual packages light sources.
The end of above-mentioned reflection shield also is equiped with lampshade.
Above-mentioned lampshade is a Transparent lamp shade, or the frosted lampshade, and the shape of lampshade is the quadratic surface lampshade, or the plane lampshade.
The utility model is owing to adopt the outside of led light source to be equiped with reflection shield; The cross sectional shape of reflection shield is a dovetail groove; And the inner surface of reflection shield is provided with optical coating, and the outer surface of reflection shield is provided with the structure of the heat radiation coating with heat loss through radiation function, therefore; The utility model can be realized the Illumination Distribution of approximate uniform rectangular hot spot, has very high uniformity of illuminance and utilization ratio of optical energy.In addition, it is main radiating mode that the utility model adopts with the radiation, has alleviated the volume and the quality of ball bubble greatly, and the utility model convenient disassembly, and volume is little, in light weight.The utility model is that a kind of Illumination Distribution is even, and the bright fringes phenomenon can not occur, the convenient and practical reflection shield that is used for LED lamp bar.
