Abstract

The invention provides a device for continuously detecting integrative luminescence properties of a light emitting diode (LED) light source, which comprises a detected sample seat and LED property detecting devices. The device is characterized by also comprising a guide rail, a measure and control device and a data processor, wherein the detected sample seat is arranged on the guide rail; at least two detecting stations are arranged along the guide rail, and each detecting station is provided with the LED property detecting device; the detected sample seat is controlled by the measure and control device to move along the guide rail; the LED property detecting devices detect a detected sample fixed on the detected sample seat and transmit detecting signals to the measure and control device; and the data processor reads the detecting signals from the measure and control device and analyzes the detecting signals. The device solves the problems of low integration level, complicated detecting procedure, and the like universally existing in the prior LED detecting instruments, has more comprehensive and integrative luminescence property detecting capability and effectively realizes an on-line continuous detecting function.

Description

technical field [0001] The invention relates to the technical field of optical detection, in particular to a device for continuous detection of comprehensive luminescence characteristics of LED light sources. Background technique [0002] LED is a solid light-emitting device made of semiconductor materials. It is also a typical new "green" high-efficiency light source. It has the advantages of high efficiency, low power consumption, long life, and fast response. In addition, its small size , vibration resistance, reliability and durability, suitable for mass production, and can meet the application requirements of various lighting and display. [0003] In all aspects of LED application products from design, production, testing to entering the market, it is hoped that the characteristics and quality of LED light sources can be accurately and reliably detected. The international standard CIE 127-1997 "Measurement of LEDs" and the industry standard "Test Method for Semiconduct...
