Optical measurement system and optical measurement device

Abstract

The invention discloses an optical measurement system which is used for measuring the optical properties of an object to be measured; and the optical measurement system comprises the object to be measured, an optical detection module, a light guide module and an analysis module. The optical measurement system utilizes the light guide module to receive axial light from the light emitted by the object to be measured for carrying out optical property analysis. Therefore, the light intensity of the light emitted by the object to be measured can be accurately measured, and the optical properties of the axial light of the object to be measured can be obtained.

Description

technical field [0001] The invention relates to an optical measurement system, more specifically, an optical measurement system capable of simultaneously detecting the total luminous flux of an object to be measured and the optical characteristics of axial light. Background technique [0002] At present, when the light-emitting diode (LED) point measuring machine measures each object under test, it must use an integrating sphere or a large-area light sensor to measure the light energy at all angles to obtain such as total luminous flux, color temperature, color coordinates, and color rendering. Optical properties such as coefficients or spectra. As the production capacity of the DUT increases, the detection demand of the DUT also increases. [0003] However, when using an integrating sphere, its volume and edge angles are reflected multiple times, resulting in energy loss of light. Theoretically, each integrating sphere can only test one DUT at a time. Therefore, in order...
