The detection system comprises a hemisphere with a cavity, a bottom plate, a three-dimensional table, a current source, an optical fiber, an optical fiber integrated panel, a beam splitter, a CCD camera, a hyperspectral imaging spectrometer and a computer. The micro light-emitting device is connected with the current source and is arranged at the center of the hemisphere, and the standard light source with known irradiance spectral distribution data is arranged at the center of the hemisphere for system calibration; the optical fiber transmits spatial light distribution to the optical fiber integrated panel, the hyperspectral imaging spectrometer collects two-dimensional images and spectral information, three-dimensional spatial light color distribution of the miniature light-emitting device is obtained through computer data processing, and the luminous flux or luminous power of the miniature light-emitting device is obtained after integration of all optical fiber light distribution. The three-dimensional space light color distribution characteristic of the light-emitting device is converted into the two-dimensional distribution characteristic, and the optical characteristic of the micro light-emitting device can be rapidly and accurately detected.

Description

technical field [0001] The invention relates to a miniature light-emitting device, in particular to a detection system and a detection method for the spatial light color distribution of a micro-light-emitting device. Background technique [0002] The spatial distribution of the light source refers to the spatial distribution of the light emitted by the light source, which reflects the spatial distribution of the light emitted by the light source. The use of scientific testing methods is the key factor to obtain accurate performance of the light source. [0003] The test of the spatial distribution characteristics of the traditional light source mainly uses the light distribution curve measurement equipment of the light source. The most common method of measuring the light distribution curve is to use the relative motion of the goniophotometer and the light source to obtain the spatial distribution of the light source. [0004] At present, the commonly used goniophotometer s...
