The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Referring to Fig. 1, full optic angle LED bulb one embodiment of the present invention is proposed.Fig. 1 is the partial sectional view of full optic angle LED bulb one embodiment of the present invention.The full optic angle LED bulb of present embodiment; Comprise cell-shell 100 and be placed in that LED in the cell-shell 100 is heat sink 200, LED lamp group and radiator 300; Said LED is heat sink 200 to be in and to be wholely set near the position on cell-shell 100 tops and with radiator 300 or to be fixed in radiator 300 ends; Present embodiment preferred heat sink 200 and radiator 300 are wholely set, so that its heat conduction efficiency is higher, radiating rate is faster.Said LED lamp group is fixed in heat sink 200 surfaces of LED; LED lamp group comprises forward lamp group 210 and side direction lamp group 220; Said forward lamp group 210 is located at heat sink 200 end faces of said LED; Said side direction lamp group 220 is located at heat sink 200 sides of said LED, and said LED is heat sink, and 200 sides become 30 ° ~ 60 ° angle with horizontal plane.Because the lighting angle of LED lamp is 120 °, forward lamp group 210 is mainly carried out luminous intensity distribution on 0 ° ~ 60 ° directions of γ in the c-of light distribution γ coordinate system, and the luminous intensity distribution on 60 ° ~ 180 ° directions of γ is then realized by the light source of side direction lamp group 220.Under perfect condition, the light-emitting area of side direction lamp group 220 (also being the side of LED heat sink 200) should be 60 ° with the angle theta of horizontal plane.But; Because the bulb outside is covered with the cell-shell 100 with diffusion, 90 ° of the most of deflection of its shape γ will be so it will change the original light emission direction of LED lamp; Make it to shift to 90 ° of directions of γ, finally cause the luminous uniformity of whole bulb not enough from 120 ° of directions of γ.And if θ is too small, then light direction will be partial to 180 ° of γ, make more light be mapped on the working of plastics that is positioned at lamp holder, thereby reduce light efficiency.Therefore θ should select from 30 ° ~ 60 °.Find that through practice optimum angle theta should be 45 °.Therefore, present embodiment has been realized the full optic angle uniform light distribution of LED bulb with lower cost on the basis that keeps LED bulb traditional profile elegant in appearance.
Further, in order further to improve the luminous uniformity in the full optic angle scope, 200 symmetries that the LED in the foregoing description is heat sink be provided with 4 sides, the LED lamp quantity of the side direction lamp group 220 on each side equates with the LED lamp quantity of forward lamp group 210.In the present industry standard, requiring the strictest to full optic angle bulb is the characteristics of luminescence requirement of Energy Star (Energy Star is hereinafter to be referred as ES) for category-A bulb (being the bulb of standard incandescent lamp shape).It requires light intensity in 0 °-135 ° of the γ to change can not to surpass 20% of average intensity in this scope, and the luminous flux in 135 ° ~ 180 ° of the γ can not be lower than 5% of total light flux.In order further to improve the luminous uniformity in the full optic angle scope, just need make that the corresponding solid angle ratio of luminous ratio and this direction of all directions is identical.Omnidirectional solid angle is 4 π, and solid angle Ω=2 π (1-cos γ) of 0 ° ~ 60 ° of in-scopes of forward lamp group 210 light emission direction γ=2 π (1-cos60 °)=π, so the ratio of the luminous flux of its bright dipping and the luminous flux of side direction lamp group 220 bright dippings is 1:3.But because the structural limitations of lamp holder direction, side direction lamp group 220 can not contribute at the light of 180 ° of γ ~ 225 ° of scopes, so the luminous flux of side direction lamp group 220 is required to be 3 times of luminous flux of forward lamp group 210.
LED is roughly Lambertian source, so the light distribution of forward LED lamp group 210 is I γ=I γ=0 °Cos γ.Two-dimentional endless belt luminous flux is considered in cross section to cross axis, can be expressed as For angle theta is 45 ° side direction LED lamp group 220, and its light intensity then is I ' γ=I ' γ=135 °Cos (γ-135 °), the luminous flux in the cross section And after the consideration structural limitations, its effective luminous flux does Therefore, the light flux ratio according to top forward that provides and side direction bright dipping should have Therefore I is arranged γ=0 °: I ' γ=135 °≈ 1:3.5.So when the LED lamp that uses when side direction lamp group 220 and forward lamp group 210 was identical, then the quantity of LED lamp should be 3.5 times of LED lamp quantity in the forward lamp group 210 in all side direction LED lamp groups 220.
For the facility that connects between power supply output and the LED; Side direction lamp group 220 should have the N group; Be that LED heat sink 200 should have N symmetrically arranged side, and the LED lamp quantity of the side direction lamp group 220 on LED heat sink 200 each side should equate with the LED lamp quantity of forward lamp group 210.According to top result, N should be 3 or 4, but owing to consider the influence of cell-shell, needs to select bigger value, so preferential side is 4 groups to the lamp group, and promptly LED heat sink 200 has 4 sides.On cover, after the cell-shell, the distribution curve flux of whole lamp is simulated, its analog result is as shown in Figure 2.Visible from analog result, in 0 ° ~ 135 ° of γ the distribution of light intensity very evenly, light intensity change only have an appointment ± 10 °.Therefore, present embodiment has satisfied the uniformity requirement of ES fully, has realized the uniformly light-emitting in the full optic angle scope of LED bulb.
