Problems solved by technology

However, in the photometer with this structure, it is impossible to measure the irradiance of the light source in 360 degrees.
In addition, the error caused by the rotation of the detector bracket is relatively large, and there is no self-calibration function
As the usage time of the detector increases, the measurement accuracy of the photometer gradually decreases

Abstract

The invention provides a goniophotometer, comprising: a support frame, which plays a supporting role; a support shaft, which is arranged laterally on the support frame; an arc-shaped rotating bracket, connected to the support shaft, which can The support shaft rotates up and down; a plurality of light detection units are arranged on the rotating bracket. According to this structure, the irradiance of the measured light source can be measured accurately and conveniently.

Description

technical field [0001] The invention relates to the technical field of optical measurement, and more specifically, to a distributed photometer. Background technique [0002] A photometer is a special instrument for measuring the luminous intensity distribution of a lamp, also called a goniophotometer. The total radiant flux, luminous efficiency, light distribution curve and other parameters of the lamp can be determined by the photometer. Lighting engineers carry out lighting engineering design according to the above parameters, and make the designed lighting scheme comply with the corresponding national and international standards. For example, in the design of road lighting, the layout of street lights can be determined according to the characteristics of the street lights used, such as radiant flux, luminous efficiency, and light distribution curve, so as to comply with national and international standards for different grades of road surfaces. Illuminance, brightness, ...
