Device and method for quickly measuring lamp space spectral distribution

Abstract

The invention discloses a device for quickly measuring lamp space spectral distribution. The device comprises a frame body, a placing base of a lamp to be measured, an optical fiber bundle, an optical switch, a spectrometer and a data acquirer, wherein one end of each optical fiber of the optical fiber bundle is arranged on the frame body in a dot matrix mode and the other end of each optical fiber of the optical fiber bundle is connected with the input end of the optical switch; and the output end of the optical switch is connected with the spectrometer. The invention also provides a quickly measuring method. The device is implemented by an optical fiber light guide mode. Compared with the conventional and common mechanical rotation type optical parameter distribution measurement method, the method accords with the actual on-line measuring requirement, is quick in measurement, makes the system design flexible, can realize multi-angle quick measurement conveniently, and is particularly suitable for realizing on-line quick measurement of the production line. Space spectral distribution can be quickly acquired by shunt detection of the optical switch, so the functionality is high.

Description

technical field [0001] The invention relates to the technical field of LED measurement, in particular to a device and method for quickly measuring the spatial spectral distribution of lamps. Background technique [0002] LED (Light-emitting diode, light-emitting diode) has many significant advantages such as high light efficiency, good monochromaticity, fast response, solid state, safety, environmental protection, long life, etc. The fourth-generation light source, with the continuous advancement of technology, has become the general trend to replace traditional lighting sources, and the era of large-scale mass production of LED lighting products has arrived. In order to guarantee the factory quality of the product, performance measurement must be carried out. As a lighting application product, the most important indicator to measure its working status is the lighting optical parameters of the product driven by a certain current. The most commonly used parameters are spatia...

AI Technical Summary

Problems solved by technology

Due to the need for mechanical rotation during the measurement process, and the measurement of many azimuth angles, the overall measurement efficiency is low. It will take more than half an hour to measure only a single lamp, and the installation work before measurement will also take more time.

For large-scale industrial production, it is impossible to meet the needs of the industrial line for fast and on-line measurement using traditional measurement methods
