Multifunctional color calibration system

Abstract

The invention discloses a multifunctional color calibration system. The multifunctional color calibration system comprises a test sample arranged on an operation table, an integrating sphere arrangedon the periphery of the test sample, a sensor probe used for collecting spectral information of the test sample, a signal transmitter electrically connected with the signal output end of the sensor probe, a computer end electrically connected with the signal output end of the signal transmitter, a control chip electrically connected with the signal output end of the computer end and arranged in the test sample, and a mobile terminal connected with the control chip through a wireless transmission module. Light emitted by the test sample is subjected to diffuse reflection in the integrating sphere, the spectral information is collected through the sensor probe and sent to the computer end through the signal transmitter, calibration data are sent to the control chip in the sample through a color calibration feedback algorithm, cyclic testing is conducted till multi-primary-color mixed light white balance is achieved, and the mobile terminal can achieve compiling, brightness adjusting andcolor adjusting of a lamp of the test sample.

Description

technical field [0001] The invention relates to the related technical field of LED lighting, in particular to a multifunctional color calibration system. Background technique [0002] Colored LED outdoor lamps mostly use GRB three primary colors to achieve color change. Early colored LED outdoor lamps focused on product reliability, stability and cost reduction, and there were no more requirements for the quality of colored light; colored LED outdoor lamps only needed brightness Meet the requirements, simple and reliable control, cool color changes can basically meet the requirements; in recent years, the terminal market has begun to put forward higher requirements for the quality of light, such as requiring lamps to be able to mix the blackbody curve CCT from 2200K to 8000K, the requirements are higher In order to restore the true color of the object, more vivid colors are required; these put forward higher requirements for lamps; based on these new requirements, colored LE...

Problems solved by technology

[0005] The purpose of the present invention is to provide a multifunctional color calibration system, which aims to improve the color calibration device in the prior art. Due to its own design features, simple structure and single use mode, in the actual use process, most of the color calibration devices currently on the market Some RGB LED outdoor lamps have the disadvantage of small color gamut, and cannot calibrate the color, and with the change of time, the light decay of different color LEDs in the lamps is inconsistent, which will lead to color deviation, so that the light quality cannot be achieved. Requirements, the current corresponding control systems are also developed based on RGB three-primary colors, so it is difficult to realize the control of emerging multi-primary LED lamps, so that it cannot meet the current needs of various use of color calibration devices
