光束角相同的灯具光学性能探讨

Discussion on Optical Performance of Lamps with the Same Beam Angle

通过详尽的分析,阐明了具有相同光束角的灯具,光学性能可能并不完全相同,甚至会有很大的差别。澄清了人们对灯具光束角的模糊认识,便于更合理、更科学地进行照明设计。

Through detailed analysis,this paper clarifies that the optical properties of lamps with the same beam angle may not be identical or even very different.It clarifies people’s vague understanding of the beam angle of lamps and lanterns,so as to make lighting design more reasonable and scientific.
