The specific embodiment
Understand for technical characterictic of the present invention, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in figures 1 and 3, be a preferred embodiment adjusting the light distribution structure of direction of illumination of the present invention, this light distribution structure is used for the light source of lighting is carried out luminous intensity distribution, and it can strengthen the intensity of illumination of a certain direction.As shown in Figure 1, this light distribution structure comprises first reflector 100 that is positioned at light source 300 tops, and second reflector 200 that vertically is provided with, second reflector 200 is positioned at the side of described light source 100, second reflector 200 be used for the light of light source 300 directives second reflector 200 to second reflector 200 right regional reflex, to strengthen this regional illumination, when needing to strengthen the illumination of a certain direction, adjust this light distribution structure, second reflector 200 is got final product towards this direction, because light is through after the luminous intensity distribution, illumination is more even, can avoid because the dazzle that the light source direct projection brings.
Referring to Fig. 2, in this preferred embodiment, second reflector 200 comprises vertical portion 210 and is positioned at the rake 220 that 210 belows, vertical portion link to each other with vertical portion 210, rake 220 is to away from light source 300 lopsidedness, junction 231 arc transition of vertical portion 210 and rake 220, luminous intensity distribution being impacted because transition is level and smooth inadequately to prevent, is that illumination variation is level and smooth inadequately.Further, in order to make illumination more even, the surface of second reflector is provided with many parallel vertical projections 232 and lateral projection 233, vertical projections 232 and lateral projection 233 are interspersed, light by light source 300 directives second reflector 200 is throwed away through repeatedly reflecting the back on second reflector 200, make illumination more even.Be understandable that, can vertical projections 232 only be set as required or lateral projection 233 only is set, or make projection into groove shapes, can reach similar light distribution effect equally, also the surface design of second reflector 200 can be become irregular raised or sunken, perhaps be designed to coarse diffuse surface, these can play and make the illumination effect of uniform.
As shown in figures 1 and 3, in the light distribution structure of the present invention, second reflector 200 is arranged on first reflector 100, concrete is, upper end in the vertical portion 210 of second reflector 200 has flanging 211, flanging 211 is provided with fixing hole, and hold-down screw passes these fixing holes second reflector 200 is fixed on first reflector 100.Direction of illumination for more convenient adjustment light fixture, the fixed hole position 111 that many groups are used for fixing second reflector 200 can be set on first reflector, these fixed hole positions 111 can be along all directions setting, when needing to adjust direction of illumination like this, the adjustment of direction of illumination can be realized in the position that only needs to change second reflector 200, and it is more convenient that the direction of adjusting whole light distribution structure is adjusted direction of illumination.It will be appreciated that, what second reflector 200 of the present invention was uninevitable is fixed in first reflection 100, also can fix second reflector 200 by support bracket fastened mode is set in lamp interior, the relativeness that only needs to guarantee first reflector 100 and second reflector 200 gets final product.
Light distribution structure of the present invention can be used for circular lighting lamp, as shown in Figure 4, be a preferred embodiment of light fixture with light distribution structure of the present invention, it is a platform lamp, and this platform lamp has the light distribution structure of telling about in the preferred embodiment of above-mentioned light distribution structure.Referring to Fig. 1 and Fig. 4, this platform lamp comprises lamp housing 400 and lamp housing 400 is divided into the thermal insulation board 410 of electric chamber and light-source chamber, the lower surface of thermal insulation board 410 is provided with the joint pin 411 that is used for fixing first reflector 100, be provided with light source 300 in the light-source chamber, the top of light source 300 is provided with first reflector 100, the middle part of first reflector 100 is provided with the through hole 101 that passes for light source 300, the optical axis coincidence of the axis of this first reflector 100 and light source 300, the side of light source 300 vertically is provided with second reflector 200, second reflector 200 is fixed on the lower surface of first reflector 100 by the flanging 211 on its top, with strengthen second reflector over against the intensity of illumination of direction.The inner surface of first reflector 100 can be to be parabola, sphere, the conical surface or ellipsoid, adopts the conical surface in the present embodiment, and the cone angle of the conical surface is 15～20 °.In the present embodiment, light source 300 adopts Metal halogen lamp, and it is threaded on the lamp socket that is arranged on the thermal insulation board.First reflector is formed by aluminium 1070 spinning, and its inner surface is through the sandblast oxidation processes.
Fig. 5 shows the distribution curve flux figure of the preferred embodiment of light distribution structure of the present invention, with remove second reflector, 200 resulting distribution curve fluxs as shown in Figure 6 and compare, can be clearly seen that, after removing second reflector 200, light is symmetrically distributed, after increasing by second reflector 200, distribution of light no longer the symmetry, second reflector 200 right direction strengthen to some extent.
In conjunction with the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
