An electroluminescence material for LEDs is provided to ensure an excellent luminous efficiency by accomplishing energy transfer between organic polymer electroluminescence compounds on nanoagglomerates. An electroluminescence material for LEDs is a nanoagglomerate obtained by mixing 100 parts by weight of any...
(4) 光效(luminous efficiency):即光源的发光效率,就是用光源发出的总光通量除以它所消耗的功率所得之商,简称光效,其单位为流明每瓦(lm/W)。发光效率值越高,表明照明器材将电能转化为光能的能力越强,即在提供同等亮度的情况下,该照明器材的节能性越强;在同等功率下,该照明器材的照明性越强,即亮度越大。通常...
Instead, scientists are focusing on improving the luminous efficiency of LED. In mid 1970s, LED can produce green, yellow, orange light, luminous efficiency of 1 LM / W, to the use of gallium arsenide and aluminium phosphide in mid 1980s the first generation of high brightness red, yellow...
