The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described further:
See also Fig. 1 to Fig. 6, the utility model relates to a kind of light fixture optical module, and its better embodiment comprises reflector 10, lens 20 and base 30.
The inwall of this reflector 10 is the some polygon reflective convex of distribution such as quadrangle reflective convex evenly, the inwall of this reflector 10 extends some annular boss to axis direction, the direction of the cross-sectional area of some annular boss along light-emitting window to light inlet dwindled one by one, so, can optimize the curvature parameters of reflector.The cross-sectional area of annular boss can be circle, also can be polygon such as quadrangle.Two cartridge parts 17 that are positioned at the light inlet both sides are extended in the outer wall of this reflector 10 bottom.This cartridge part 17 can be the projection that cross-sectional area is L-type, also can be the cylindrical body of rod.
These lens 20 comprise incident curved surfaces 23, joint face 22 and bright dipping curved surface 21.Incident curved surfaces 23, joint face 22 and bright dipping curved surface 21 surround an occluding surface.This incident curved surfaces 23 comprises non-smooth flat 231 and the smooth annular surface to downward-extension from the periphery of non-smooth flat 231, this non-smooth flat 231 and this smooth annular surface surround a light source receiving space, so that be placed on the incident curved surfaces 23 that light that the light source in this light source receiving space sends all passes these lens 20, thereby improve the utilization ratio of luminous flux, the luminous energy of avoiding waste.In the present embodiment, this non-smooth flat 231 is frosted plane or pearl face.This joint face 22 is circular plane, which is provided with two relative installation portions 24.In the present embodiment, this installation portion 24 is cylindrical shape.The cross-sectional area of this bright dipping curved surface 21 is and becomes gradually large circular area from top to bottom.The lens arrangement spotlight effect of the present embodiment is better, but the luminous flux that the full use light source sends.
