Abstract
The utility model discloses a kind of LED wire type bulb lamp, comprise glass cell-shell, upper bracket, LED lamp bar, stem stem, LED power supply, lamp holder, seal wire, also comprise the reflector layer bottom glass cell-shell.The thickness of reflector layer is 1 μm ~ 200 μm, plays the effect of reverberation, and the uneven illumination solving existing full angle emitting bulb is even, center point light intensity problem on the weak side, improve uniform illumination degree, avoid aperture and hot spot problem, light loss is little, energy-conserving and environment-protective.
Description
Technical field
The utility model relates to a kind of LED bulb, particularly relates to a kind of LED wire type bulb lamp with reflector layer.
Background technology
Due to LED long service life, energy consumption is low, economize energy is remarkable, therefore LED lamp has been widely used in daily life, as LED bulb as light source.The LED bulb of full angle luminescence enjoys great popularity, but is difficult to realize full angle uniformly light-emitting due to current single LED lighting angle.Therefore, the uneven illumination how improving full angle LED bulb is even, aperture, hot spot, center point light intensity problem on the weak side become significant problem in LED bulb technologies.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of LED wire type bulb lamp with reflector layer.
The purpose of this utility model is achieved through the following technical solutions: a kind of LED wire type bulb lamp, comprise glass cell-shell, upper bracket, LED lamp bar, stem stem, LED power supply, lamp holder, it is characterized in that, also comprise the reflector layer bottom glass cell-shell, reflector layer is positioned at inwall or the outer wall of glass cell-shell.
Further, reflector layer comprises reflective internal layer and reflective skin, and reflector layer is positioned at the inwall of glass cell-shell, and reflective internal layer is between glass inner wall and reflective skin, and the refractive index of reflective internal layer is higher than reflective outer field refractive index.
Further, reflector layer comprises reflective internal layer and reflective skin, and reflector layer is positioned at the outer wall of glass cell-shell, and reflective skin is between glass envelope shell outer wall and reflective internal layer, and the refractive index of reflective internal layer is higher than reflective outer field refractive index.
The beneficial effects of the utility model are: reflector layer plays reflex, thus the uneven illumination solving existing full angle emitting bulb is even, aperture, hot spot, center point light intensity problem on the weak side, improve uniform illumination degree, light loss is little, energy-conserving and environment-protective.

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 LED wire type bulb lamp with reflector layer, comprise glass cell-shell 1, upper bracket 2, LED lamp bar 3, stem stem 4, LED power supply 5, lamp holder 6, seal wire 9, also comprise the reflector layer 8 be coated on bottom glass cell-shell 1, because glass cell-shell 1 is transparent material, reflector layer 8 can at glass cell-shell 1 inwall or outer wall.Reflector layer 8 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 reflector layer 8 is positioned at the inwall of glass cell-shell 1, reflective internal layer is between glass cell-shell 1 inwall and reflective skin, and when reflector layer 8 is positioned at the outer wall of glass cell-shell 1, reflective skin is between glass envelope shell 1 inwall and reflective internal layer.The High-low Match of refractive index can form total reflection effect, increases reflectivity and the light filling effect of 3-5%.
Reflector layer 8 thickness is 1 ~ 200 μm, can be the metal alloys such as the metals such as Au, Ag, Al, Cu, Si, Fe, Ni, Cr, or NiCr, SiAl, TiAl, ZnAl, AuGe, CuInGa, or ITO, TiOx, AlOx, CrOx, Y

3, other compounds such as ZnS, or the organic matter such as PTFE, Parylene compound, but be not limited thereto; Also can for be evenly distributed with refractive index higher than 1.9 the silica-gel coating of glass microballoon, the segment beam of bulb axis periphery can be reflexed to the front that light fixture needs to irradiate by reflector layer 8, in order to improve the light intensity utilization rate of bulb, strengthen the light exposure intensity in bulb irradiation direction, thus supplement the light intensity of center point.Reflector layer 8 can be coated on glass cell-shell 1 by methods such as vacuum evaporation, electron beam evaporation, magnetron sputtering, CVD depositions.
Fig. 3 is the illumination effect figure of the LED wire type bulb lamp of no-reflection layer, as can be seen from Figure, uneven illumination is even, center point light intensity is on the weak side, and in the utility model, because the reflector layer 8 of segment beam through glass cell-shell 1 reflects, enhance the light intensity of center position, make its luminescence more evenly (as shown in Figure 4).
