The utility model aims at providing a structure sets up rationally and is favorable to improving the lamps and lanterns optical reflector of illuminating effect.
The utility model discloses realize the technical scheme of purpose is a lamps and lanterns optical reflector, including the support, fix the lamp cup at support top and the light source that is in support top center, the top surface of lamp cup is fixed with the diffusion piece, the lamp cup is horn shape cup and cross section for the rectangle lamp cup, the top surface of rectangle lamp cup is fixed with the cross, the end limit of cross is in rectangle lamp cup sideline central point and puts, the bottom surface center integrated into one piece of cross has the circular reflection face, four angles departments of rectangle lamp cup are big-end-up's circular arc plane of reflection, and the junction of adjacent circular arc plane of reflection is bellied triangle-shaped reflection cambered surface, when the light of light source shines, central light reflects to lamp cup inner wall through circular reflection face to shine to after circular arc plane of reflection and triangle-shaped reflection cambered surface.
The diffusion sheet is a cloth-grain lens.
The light source is the COB light source.
The top surface of support is provided with the screens annular, integrated into one piece has the screens bulge loop on the outer wall of lamp cup, the bottom surface card of screens bulge loop is gone into spacing in the screens annular.
The utility model discloses has positive effect: the utility model discloses a structure sets up rationally, its lamp cup adopts the rectangle lamp cup, cooperation cross frame, there is the circular reflecting surface simultaneously at the bottom surface center of cross frame, cooperation circular arc reflecting surface and triangle-shaped reflection cambered surface, thereby light is when shining, the light at center can be through circular reflecting surface to the reflection of lamp cup inner wall, pass through the circular arc reflecting surface and reflect the clearance department of cambered surface reflection back follow cross frame and outwards shine again, thereby make the central light intensity be less than the border light intensity, improve the effect of dispersion illumination, the suitability is strong and the practicality is good.
