Problems solved by technology

[0002] LEDs are used more and more widely in daily life. As we all know, in order to increase the luminous flux of ordinary LED lamps or LED energy-saving lamps, a kind of Guhe paper is used to achieve the reflective effect and increase the output luminous flux, but Guhe paper is expensive and expensive. It is not easy to process and shape. Usually there are only two ways to process Guhe paper: die-cutting after hot-press forming or direct die-cutting. The dimensional tolerance is not easy to control and the shape is greatly restricted. The production speed is slow and the defective rate is very high. Injection-molded reflective cups cannot achieve a reflective efficiency of more than 95%, so a new type of reflective cup injection-molded with special PC reflective plastic granules is currently needed to solve the above problems

Abstract

The invention relates to a light reflecting cup, a light reflecting cup manufacturing method and an LED lamp applying the light reflecting cup, and discloses the light reflecting cup prepared by injection molding of PC light reflecting plastic particles and comprising a cup body and a cup bottom; the upper part of the cup body is provided with an opening, the cup bottom is provided with an opening and mounting feet, and the mounting feet are each provided with a mounting hole; the cross section of the cup body is in the shape of a trapezoid. The light reflecting cup is easy to process and mold, fast in production speed, and high in rate of finished products, and has the light reflecting rate reaching up to 95%.

Description

technical field [0001] The invention relates to the field of LED equipment, in particular to a reflective cup, a method for manufacturing the reflective cup and an LED lamp using the reflective cup. Background technique [0002] LEDs are used more and more widely in daily life. As we all know, in order to increase the luminous flux of ordinary LED lamps or LED energy-saving lamps, a kind of Guhe paper is used to achieve the reflective effect and increase the output luminous flux, but Guhe paper is expensive and expensive. It is not easy to process and shape. Usually there are only two ways to process Guhe paper: die cutting after hot pressing or direct die cutting. The dimensional tolerance is not easy to control and the shape is greatly restricted. The production speed is slow and the defective rate is very high. Ordinary plastic Injection-molded reflective cups cannot achieve a reflective efficiency of more than 95%, so a new type of reflective cup injection-molded with sp...
