Abstract
The invention is suitable for the field of illumination and provides a reflector, a lamp and illuminating equipment. The reflector has a mirror symmetrical structure and comprises a first reflecting surface and a second arc-surface reflecting surface, wherein the first reflecting surface has a V-shaped concave structure; the second arc-surface reflecting surface is formed by extending the first reflecting surface outwards; and diffuse reflection layers are formed on the inner surfaces of the first reflecting surface and the second reflecting surface. A V-shaped reflecting surface is formed in the center of the reflector and an arc-shaped reflecting surface is formed at the periphery of the V-shaped reflecting surface, so that light rays can be reflected by multiple angles repeatedly. Due to the combination of a special structure and the diffuse reflection layer on the inner surface of the reflector, the light rays are subjected to diffuse reflection based on repeated multi-angle reflection and reflected light with highly uniform light intensity distribution is formed. Therefore, Lambert light distribution is realized, a glare phenomenon is avoided in a large scale, illuminating effect is improved and vision can be protected.

The embodiment of the invention also provides a kind of light fixture, and this light fixture comprises above-mentioned reflector.
Another object of the present invention is to provide a kind of lighting apparatus, this lighting apparatus comprises above-mentioned light fixture.
Below in conjunction with specific embodiment specific implementation of the present invention is described in detail:
Embodiment one:
Fig. 1 shows the perspective view of the reflector that first embodiment of the invention provides; Fig. 2 shows the cross-sectional view of the reflector that first embodiment of the invention provides; Fig. 3 shows the user mode schematic diagram of the reflector that first embodiment of the invention provides, and for convenience of explanation, only shows the part relevant with the embodiment of the invention.
Please in conjunction with the accompanying drawings 1,2, the concrete structure of this reflector is as described below: this reflector has first reflecting surface 1 of " V " type sunk structure, and by stretch out second reflecting surface 2 of the cabochon that forms of first reflecting surface 1, the inner surface of first reflecting surface 1 and second reflecting surface 2 is equipped with diffuse reflector, and reflector integral body is mirror symmetrical structure.The preferred aluminium alloy of the material of this reflector.Can realize uniform light distribution by " V " type first reflecting surface and cabochon second reflecting surface reflector that constitutes that matches, improve glare phenomenon.
Concrete, the structure of this reflector can be the domes of strip, is provided with " V " type groove structure of strip in the reflector center of top, and promptly first reflecting surface 1 is extended to both sides by first reflecting surface 1, promptly forms second reflecting surface 2 of cabochon.It can be regarded as by a middle position has the direction extension certain distance of the circle arc curve edge in one " V " type district perpendicular to plane, circular arc place, the final both ends open that forms, and the top has the strip arch form structure of one " V " type groove.The user mode of this strip arch form structure reflector is seen accompanying drawing 3, and this reflector is installed on the inside of lamp outer casing 5, the light source 4 of strip be positioned at first reflecting surface 1 under, and light source 4 and best coplane of reflector lower limb or approximate coplane.The light that light source 4 sends forms the higher emergent light of the uniformity after first, second reflecting surface diffuse reflection, its reflecting effect there is shown the index path of light in reflector that three LEDs light sources send as shown in Figure 5.Further combined with accompanying drawing 6, the first curve L1 is the photometric curve on first plane among the figure, and the second curve L2 is the photometric curve on second plane, and wherein, first plane is that second plane is a horizontal plane by the vertical plane on first reflecting surface, 1 base.From photometric curve as can be seen, the light distribution effect of this reflector is better, and the spatial light intensity distribution uniform has realized lambert's type luminous intensity distribution.
Please further in conjunction with the accompanying drawings 4, as the another kind of form of present embodiment, the concrete structure of reflector can also be the ball crown type structure that the center of top position has the pyramid type depressed area.It can regard the three-dimensional structure that the circle arc curve that has one " V " type district by a middle position rotates a circle and forms around its symmetry axis as.The pyramid type depressed area that is positioned at reflector center of top position is first reflecting surface 1, the cabochon structure of joining with first reflecting surface 1 is second reflecting surface 2, this reflector is applicable to circular luminaire, this moment, the light source of light fixture was spot light or approximate spot light, place first reflecting surface 1 under, its luminous intensity distribution principle is identical with the luminous intensity distribution principle of above-mentioned strip arch form reflector, does not repeat them here.
In order effectively to improve light distribution effect, can control the relevant parameter of reflector, wherein, the central angle θ of first reflecting surface 1 (is the two sides angle of " V " type groove of strip arch form structure reflector, or the drift angle of the pyramid type depressed area of ball crown type reflector) is controlled to be 95 °～105 °, by first, the central angle alpha of the reflector body correspondence that second reflecting surface constitutes is 110 °～120 °, the ratio of the central angle of the isocentric circular arc that first reflecting surface 1 is corresponding with reflector body is 10%～15%, the arc radius of second reflecting surface 2 is 85～95mm, the openings of sizes of the reflector (vertical range between two lower limbs of promptly long bodily form arch form reflector, or the opening diameter of ball crown type reflector) is 145～155mm, can obtains reverberation more uniformly like this.
Embodiment two:
In embodiments of the present invention, can the relevant parameter of reflector further be limited, with better realization uniform light distribution.Wherein, the central angle θ of first reflecting surface 1 is set to 100 °; The arc radius of second reflecting surface 2 is 90mm; The openings of sizes of reflector is 150mm, can realize best light distribution effect like this.
Embodiment three:
Further combined with accompanying drawing 1, the installation of reflector for convenience, present embodiment can be on the basis of the foregoing description, in the edge of reflector plane is set and prolongs limit 3, prolong the part of limit 3 as reflector, with first reflecting surface 1 and second reflecting surface 2 are one-shot formings, above three is structure as a whole.Assembling is during light fixture, will prolong limit 3 and be connected with lamp outer casing with sticking card, clamping or by the fixture ways of connecting.
The central authorities of reflector of the present invention have first reflecting surface of one " V " type, and the periphery of first reflecting surface is second reflecting surface of cabochon, and this structure helps making that light takes place repeatedly, multi-angle remission; The diffuse reflector that this special construction is provided with in conjunction with the reflector inner surface; make light repeatedly, carry out diffuse reflection on the basis of multi-angle remission; form light distribution reverberation highly uniformly; realized lambert's type luminous intensity distribution; avoided glare phenomenon significantly; improved illuminating effect, but and vision protection.Prolong the limit in the reflector edge setting, be convenient to install.When the present invention uses as the reflector of Grille lamp, only need row's light source to get final product, both saved production cost, reduced heat exhaust again.
The above only is preferred embodiment of the present invention, not in order to restriction the utility model, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
