Light-receiving apparatus capable of increasing light-receiving magnitude and angle

Abstract

The invention is a light-receiving apparatus capable of increasing light-receiving magnitude and angle. It includes an integrating sphere and a supporting fixture wherein the integrating sphere is a hollow spherical ball in which a reflecting surface is formed on its inner wall surface. A light-receiving pillar and at least a light-emitting pillar are provided on the outer wall of the integrating sphere. A light-receiving hole and a light-emitting hole are set up on the light-receiving pillar and the light-emitting pillar respectively for connecting to space in the integrating sphere. The supporting fixture includes a locating ring and a transparent glass plate. The locating ring can join the light-receiving pillar. The transparent glass plate is set on top side of the locating ring for supporting and placing a light-emitting device to be tested. After light generated by the light-emitting device to be tested entering the integrating sphere, it can be reflected and diffused uniformly by reflecting surface in the integrating sphere before being projected to an optical detection apparatus through the light-emitting hole for carrying out detection. Accordingly, since the light-emitting device to be tested can be located at a position next to the light-receiving hole by the transparent glass plate, light-receiving magnitude and angle of light, generated by the light-emitting device to be tested which is received by the light-receiving hole, can be increased effectively for raising accuracy of detection.

Description

technical field [0001] The invention relates to a light-receiving device capable of increasing the amount and angle of light-receiving, especially a support jig is installed on the light-receiving column of an integrating sphere, so that a light-emitting element to be tested can be positioned adjacent to the light-receiving column, so as to A light-collecting device that increases the amount and angle of light received by the integrating sphere. Background technique [0002] Light-emitting diode (Light-Emitting Diode, LED) is a semiconductor electronic component that can produce light after being powered on. Compared with traditional lighting appliances, light-emitting diodes have the advantages of high efficiency, low cost, fast response and long service life. Therefore, in recent years, it has been widely used in the fields of traffic signals, lighting equipment, display panels and even optical communications, and has become one of the most influential key technologies in ...
