Description
Technical field
The utility model relates to a kind of tester, is specifically related to the lumination of light emitting diode strength tester.
Background technology
Measure the tester of light emitting diode (LED) luminous intensity, normally regard LED as pointolite, utilization square distance law of reciprocity is being measured the illumination that is produced from 10-14 times of distance of measured device radius, and convert (calibration) becomes the numerical value of luminous intensity again.This light intensity test instrument can only measuring light intensity distribution the tested LED of approximate cosine radiator, there are not the square distance law of reciprocity in, light intensity space distribution inhomogeneous and asymmetric LED very strong for the LED, the directive property that are not cosine radiator between the luminous intensity that obtains with the luminosity detector measurement and the illumination of tested surface.In addition, in fact light emitting diode shell complex figure has extended device area, thereby tested LED can not be counted as pointolite in certain distance range.In addition, the adjusting function of whole tester is poor.
Summary of the invention
At above-mentioned technical matters, the purpose of this utility model provides a kind of lumination of light emitting diode strength tester of being convenient to regulate in test process.
