Abstract
Recently LED is used in many ways. Especially white LED begins to be used for indirect lighting, for example spot light or downligth. In region of lighting, higher luminous flux is required compared with other regions. We develop a high power white LED module. The luminous flux, color temparature and Ra are respectively 120 lm, 5000K and 70. This time we could make designed color and control the range of varied color among products to grind the surface of florescent layer.
