LED单管标准色板变角度色度校准装置 LED tube standard chromaticity plate variable angle chromaticity calibration device

摘要

采用二维自动转动控制结合伺服电机、传感器及测量软件等设计了一种可实现光源和物体的表面空间变角度光度、色度等参数测量的多用校准装置, 解决了目前LED单管、显示器和标准色板等三类产品光度色度参数需使用独立测量装置的问题。结果显示可完成LED单管总光通量、CIE条件A/B场平均发光强度、等光强/照度曲线、小尺寸显示器光度色度和物体表面变角度色度等参数的测量。平均发光强度、总光通量、Y值和色品坐标与标准值偏差分别为: -1.8%、1.5%、0.9和0.005, 该装置测量精度高、功能切换方便、自动化水平高、操作简单, 达到设计要求。

Abstract

A multipurpose calibration device has been successfully designed to measure variable angle luminosity of light source and body surface and chroma parameter, which adopts two-dimensional automatic rotation control combined with servo motor, sensor and measurement software. It solves problems that measurement devices to measure the luminosity and chromaticity parameter are all independent device. Results show that this device can measure such parameters as total luminous flux, A/B field average luminous intensity with CIE, isocandela/illumination curve and small size display photometric chromaticity and variable angle chromaticity of body surface. Average luminous intensity, luminous flux, Y value and chromaticity coordinates and the standard deviation of the device are-1.8%, 1.5%, 0.9 and 0.005 respectively. So this device has met design requirements of high accuracy, convenient function switch, high level of automation and simple operation.
