Abstract

The invention discloses an LED lighting fixture color spatial distribution test device, which comprises a base, a mounting seat, a reflective mirror, a first synchronous motor, a rotary installation plate, a lamp arm, a second synchronous motor, a spectrometer, an adjustable light-shielding barrel and a fiber-optic probe. Compared with the prior art, the LED lighting fixture color spatial distribution test device is simple in structure and powerful in function, which is capable of realizing the intelligent test. Meanwhile, based on the weighted calculation of a standard color formula, the LED lighting fixture detection accuracy is improved, and the test error is reduced.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for color space distribution of LED lighting appliances. Background technique [0002] Due to the particularity of light emission of LED lighting appliances, they are very different from traditional electric light sources in terms of size, luminous flux, spectral power distribution and spatial light intensity distribution. Light) is not easy to transfer to LED lighting fixtures, including many uncertain factors, such as large differences in relative spectral power distribution, uneven spatial distribution of light chromaticity, etc. The measurement method of a simple integrating sphere with a spectrometer cannot meet the measurement of the color space distribution characteristics of LED lighting appliances. The current ordinary goniophotometer cannot measure the color space distribution characteristics, and the parameters of its photometric probe are also difficult to meet the requi...
