什么是发光强度

发光强度是指点光源在特定固角范围内发出的光功率。它是衡量一个物体的亮度或强度的标准。 光源 在特定方向上。发光强度通常用坎德拉(cd)表示,用于量化光源的光输出。

从 Rayzeek 运动传感器产品组合中获得灵感。

光强度的测量考虑了人眼对不同波长光线的敏感度。它由 Vλ 光度函数决定,该函数是一个标准化模型,用于计算不同波长的感知亮度。该函数可根据眼睛的敏感度对不同波长的光功率进行加权。

发光强度对于发光二极管 (LED) 的开发、制造和质量控制非常重要。 固态照明 (SSL) 的商业市场。它可以对以下设备的光学输出进行量化 定向光源从而进行准确的比较和评估。通过了解发光强度,照明专业人员可以设计和控制照明系统,以达到理想的照明效果。
