Manufacturing technology for forming reflector by welding cutting face of reflector plate

Abstract

The invention relates to a manufacturing technology for forming a reflector by welding a cutting face of a reflector plate, and belongs to the technical field of design and manufacture of illuminating lamps. The manufacturing technology is characterized in that the reflector is manufactured by welding three layers of annular sleeves with different apertures and different gradients; the three layers of annular sleeves are manufactured by welding the first sleeve with a circular arc opening, the second sleeve with a tiny trumpet circular arc opening and the third sleeve with a trumpet circular arc opening in sequence in an equal diameter manner; the welding is ultrasonic wave cold welding. The manufacturing technology has the beneficial effects that as the reflector plate is cut by laser and smooth in edge, net size manufacturing is realized without extra accessories, and materials are saved; moreover, the cutting face of the reflector plate adopts ultrasonic wave cold welding, no protruded layer is arranged on the welding outer edge of the reflector plate, no hole exists when the reflector is matched with the housing of a lamp, and the reflector and the housing can be adhered and matched; the manufacturing technology is also beneficial to replacing a reflector in an original illuminating lamp with the same specification, and ultrahigh reflectivity surface layer materials can be applied to lamp reflectors; the illuminating efficiency and socioeconomic performance of lamps are improved.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of illuminating lamps, and in particular relates to a manufacturing process of forming a reflector by welding a cut surface of a reflective sheet. Background technique [0002] At present, the efficiency of lamps commonly used in the lamp industry generally stays at about 65%. The lighting efficiency of a lamp lies in the reflector (commonly known as "reflector") installed in the lamp holder. The basis for improving the efficiency of the reflector is usually determined by the reflectivity of the material and the ideal optical design; the ideal surface layer material with high reflectivity This is related to the expected development of the material industry; currently there are surface materials with ultra-high reflectivity (≥95%) on the market, but it is difficult to process them into ideal lamp reflectors in the traditional way, mainly because of this ultra-high reflectivity The r...

Problems solved by technology

Conventional welding is to overlap and weld the edges of the reflectors, or to bend and weld the edges; in this way, there is a protruding layer at the place where the outer edges of the reflectors are overlapped and welded, and there will be pores when the reflector is matched with the lamp cover, and it cannot be attached; Not conducive to replacing reflectors in old lighting fixtures of the same specification
