摘要

LED灯的光通量不仅受电流的影响

还受到结温变化的影响.针对传统LED调光存在只改变电流大小而忽略结温变化对光通量影响所存在的不足

结合LED结温和管脚温度存在特定的关系

利用实验装置采集HL001WY型GaN基白光LED在不同管脚温度和正向电流下的光通量实验数据并进行二次项趋势回归

利用定标和归一化方法建立光通量、电流以及管脚温度三者变化关系的数学模型.计算结果表明

利用该方法建立的模型得到的计算数值与实验实际测量值的相对误差小于4.5%.

Abstract

LED light flux is affected not only by current

but also by the junction temperature change. The traditional LED dimming method typically only changes the current and ignores the junction temperature changes. In order to fix this downside

a mathematical model was established based on the relationship among the luminous flux

current and pin temperature that can show the junction temperature of LED. The luminous fluxes of HL001WY type GaN-based white LEDs were tested at different currents and pin temperatures

and the experimental data were quadratic term trend regression. By using calibration and normalization method

the mathematical model was established. The calculations show that the relative error between the calculated value and the actual measured value is less than 4.5%.
