Detailed description of the invention
As Figure 1-Figure 4, this utility model is the LED filament oriented lamp of a kind of glass-reflected type, including glass cell-shell 1, LED filament 2, stem stem 3, lamp holder 4 and driving power supply (not shown).
Described glass cell-shell 1 seals with stem stem 3 vacuum, is filled with low viscosity high thermal conductivity gas in glass cell-shell 1.Described stem stem 3 surface is coated with the coat of metal, and this coat of metal includes aluminium lamination or silver layer.Described LED filament 2 welds together with stem stem 3, and the lower end of stem stem 3 is fixed on lamp holder 4, drives power supply to be arranged in lamp holder 4.
Inwall or the outer wall of described glass cell-shell 1 are coated with coating, coating covers to lamp holder 4 position from top, forming the cladding portion 12 without cladding portion 11 and middle and lower part at top, glass cell-shell 1 covers on the lower end of the LED filament 2 and outside of stem stem 3 and the glass cell-shell 1 being fixed together and is fixed on lamp holder 4.Glass cell-shell 1 is internal can be hydrogen, nitrogen or noble gas for being full of low viscosity high thermal conductivity gas, and noble gas is helium, argon or neon etc., so can pass through conduction of heat, and the heat conduction produced by LED filament 2 is to outside.The internal cladding portion 12 of glass cell-shell 1 plays the effect that reflection LED filament 2 emits beam, LED filament 2 is luminous, fraction light reflexes to glass cell-shell cladding portion 12 through stem stem 3, reflect through cladding portion 12 again, from launching without cladding portion 11, major part light is reflected by cladding portion 12, then from glass cell-shell 1 launching without cladding portion 11, separately some is directly from glass cell-shell launching without cladding portion 11.
It should be noted that the inner and outer wall of glass cell-shell 1 is coated with coating, the propagation principle of its light is just as.
The arrangement mode of described LED filament 2 filament has two kinds:
Arrangement mode 1: described LED filament 2 is around stem stem 3 array arrangement, by LED chip light-emitting area outwardly, facing to glass cell-shell 1 cladding portion 12, improves light and launches the efficiency through glass cell-shell 1 reflection.
Arrangement mode 2: as shown in Figure 5-Figure 8, described LED filament 2 ' is arranged around stem stem 3 ' skewed crossing, by LED chip light-emitting area towards glass cell-shell 1 ' without cladding portion, improve light and launch the efficiency directly sent without cladding portion 11 ' from glass cell-shell 1 ', reduce the light energy consumed because of catadioptric.
Operation principle of the present utility model:
As Figure 1-Figure 4, glass cell-shell 1 cladding portion 12 and stem stem 3 constitute an entirety, and after LED filament 2 and stem stem 3 molding, point is welded on stem stem 3.The overlay coating of stem stem 3 processes, and adds reflecting effect, reduces the light refraction by clear glass stem stem 3 and absorbed, and the light lost.The effect that glass cell-shell 1 cladding portion 12 plays is to be reflected by the most of light sent from LED filament 2, from glass cell-shell 1 launching without coating 11, within beam angle well controls to spend at 8 degree-120, thus considerably increase the luminous flux in 120 degree of conical solid angle, light past 80% exports, and has reached the standard of oriented lamp.It addition, can be by adjusting coating material and thickness.Optimize luminous intensity distribution, increase the luminous flux in 120 degree of conical solid angle.
Emphasis of the present utility model is that stem stem surface is coated with coating.
The preferred embodiment of the present invention is only intended to help to illustrate the principle how present invention realizes oriented lamp.Preferred embodiment does not has all of details of detailed descriptionthe, is not intended to the detailed description of the invention that this invention is only described yet.This specification is chosen and specifically describes embodiment, is to preferably explain the principle of the present invention and actual application.The present invention is only limited by claims and four corner thereof and equivalent.The specific embodiment being only the application disclosed above; as long as the scheme novel according to this and theoretical foundation, as LED filament oriented lamp scheme, any amendment made within every design philosophy in the present invention and principle; equivalent and improvement etc., within should be included in scope.
