High-speed optical sensing apparatus and system capable of simultaneously sensing luminous intensity and chroma

Abstract

The invention discloses an optical high-speed sensing device that is used for measuring the illumination intensity and the color intensity of a light emitting diode (LED) to be measured on an LED light bar which has a plurality of LEDs and comprises an optical detector, a light-collecting lens set, an optical splitter and a baffle set, wherein, the optical detector is used for detecting the illumination intensity of the LED to be measured; the light-collecting lens set is used for leading the lights to converge into a color analyzing device; the optical splitter is aligned with the LED to be measured and used for splitting and projecting the lights that are generated by the LED to be measured into the optical detector and the light-collecting lens set; the baffle set is arranged between the optical splitter and the LED to be measured and is provided with an opening aligned with the LED to be measured, the light generated by the LED to be measured partially passes through the plural openings and radiates into the optical splitter, the baffle set shields the oblique light generated by other LEDs not to be measured. The optical high-speed sensing device can lower the complexity of the sensing operation and effectively shorten the operation time, thus satisfying the high-speed measurement requirements of production lines.

Description

technical field [0001] The invention relates to an optical measurement system, especially a high-speed optical sensing device and system capable of simultaneously sensing luminous intensity and chromaticity. Background technique [0002] At present, there are standard measurement systems available for LED chips and packaged LED lamps, but there is a lack of appropriate measurement systems for LED light bars. A common practice is to directly use the measurement system used for LED chips and LED lamps to detect LED light bars. [0003] Measuring systems for measuring LED chips and LED lamps only have to measure a single light source. In contrast, the LED light bar has multiple LED chips, that is, multiple independent light sources that emit light at the same time, and each LED chip needs to individually detect its luminous intensity and chromaticity. If the influence of light generated by other light-emitting diode chips on the light bar cannot be effectively excluded, devia...
