摘要

在照明模拟中，通常使用单点光源发出的发光强度分布对灯具进行建模。只要灯具的尺寸远远小于到计算面的距离，这种所谓的远场方法就是有效的。这一假设在标准室内照明中通常不满足，并可能导致在预测照度和不适眩光方面出现重大误差。这项工作描述了一种基于将灯具分成N个点光源的实用近场方法。将与近场(无限N值)相关的误差作为N的函数进行评估，这种方法可以更准确地评估非均匀发射灯具的统一眩光等级。

The Usefulness of Near-Field Goniophotometry Data to Assess Illuminances and Discomfort Glare in Indoor Lighting

ABSTRACT In lighting simulations, a luminaire is usually modeled using a luminous intensity distribution emitted by a single-point source. This so-called far-field approach is valid as long as the dimensions of the luminaire are much smaller than the distance to the calculation surface. This assumption is generally not met in standard indoor lighting and may lead to significant errors in the prediction of illuminances and discomfort glare. This work describes a practical near-field approach based on splitting the luminaire into N point sources. The errors in relation to the near field (infinite value of N) are evaluated as a function of N. This approach generates a more accurate assessment of the Unified Glare Rating in the case of luminaires with non-uniform emission.
