Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As illustrated in fig. 1 and 2, a kind of 360 degree of LED bulb with reflector layer, comprise glass bulb 1, upper bracket 2, LED lamp bar 3, stem stem 4, fly silk insulation protection tube 5, lamp holder 6, plastic 7, LED power supply 8, seal wire 9 and fly silk, wherein, lamp holder 6, plastic 7, glass bulb 1 connects successively, stem stem 4 is positioned at glass bulb 1, and stem stem 4 and glass bulb 1 hot melt are integrated, seal wire 9 is arranged on stem stem 4, upper bracket 2 is fixed on the top of stem stem 4, the two ends of LED lamp bar 3 are separately fixed on upper bracket 2 and seal wire 9, LED power supply 8 is arranged in power pack 7, the two ends of LED power supply 8 are connected on stem stem 4 and lamp holder 6, flying silk insulation protection tube 5 is fixed on lamp holder 6, flying a cross-under is flying in silk insulation protection tube 5, the two ends flying silk connect stem stem 4 and LED power supply 8 respectively.
As shown in Figure 3, the inwall of plastic 7 scribbles the first reflector layer 10.First reflector layer 10 can be made up of reflective internal layer and reflective skin, and the refractive index of reflective internal layer is higher than reflective outer field refractive index, and the High-low Match of refractive index can form total reflection effect, increases reflectivity and the light filling effect of 3-5%.
As shown in Figure 4, the bottom of described glass bulb 1 scribbles the second reflector layer 11.Because glass bulb 1 is transparent, the second reflector layer 11 can be coated in inwall or the outer wall of glass bulb 1.Second reflector layer 11 also can be made up of reflective internal layer and reflective skin, and the refractive index of reflective internal layer is higher than reflective outer field refractive index.When the second reflector layer 11 is positioned at the inwall of glass bulb 1, reflective internal layer is between glass bulb 1 inwall and reflective skin, and when the second reflector layer 11 is positioned at the outer wall of glass bulb 1, reflective skin is between glass bulb 1 inwall and reflective internal layer.
First reflector layer 10 and the second reflector layer 11 coating layer thickness are 1 μm ~ 200 μm, can be the metals such as Au, Ag, Al, Cu, Si, Fe, Ni, Cr, or the metal alloy such as NiCr, SiAl, TiAl, ZnAl, AuGe, CuInGa, or ITO, TiOx, AlOx, CrOx, Y
