Security Analysis Of Indoor LED Spotlights’ Illuminant

Recently, lighting enters another new era with rapid development of LED industry. And at the same time, the study of optical radiation and biorhythm also makes LED be in an awkward position. Many experts point out the lack of semiconductor lighting, even though it has a lot of advantages. So this paper discusses the security from blue light hazards, irradiance hazards and glare rating.The first part accounts of the current status of LED briefly. The second part mainly describes the development of LED, emitting principle and related standards. The third part describes that the value of blue light hazards is obtained at 1m distance by simulating of the actual indoor illumination of LED. And the relationship between blue light hazards and power, the relationship between blue light hazards and related color temperature are found out. The fourth part describes that the value of irradiance hazards is obtained at lm distance by simulating of the actual indoor illumination of LED. And the relationship between irradiance hazards and power, the relationship between irradiance hazards and related color temperature are found out. Besides it can be obtained that there is similar law between blue light hazards and irradiance hazards through the experiment. The fifth part mainly describes the process of glare briefly, and discourse methods of glare ration in detail. At last, LED spotlights and fluorescent lamps are compared by the brightness limit curve.
