Stabilization of Optical Properties of White LED lamp for lighting

Deukhyeon Nam, Duck Hee Lee, Jung-Chul Seo

Abstract

The optical properties of white LED lamps(8W) were stabilized by aging for 900 hours. The optical properties were measured every 10 hours after the initial 100 hours of aging. The rate of change of Luminous Flux was approximately 7% for aging 900 hours. Luminous Flux, Correlated Color temperature, and Color Rendering Index were showed stabilization property after 400 hours of aging. Luminous Flux, Correlated Color Temperature, and Color Rendering Index were stabilized within 1% respectively, after 800 hours of aging.
