LED lamp with omnidirectional light distribution

摘要

An omnidirectional semiconductor light emitting device lamp (100) has a light distribution characteristic having a large range similar to that of a general incandescent lamp. The light emitting device lamp includes light-emitting diodes or LEDs (103, 106) and a diffusion cover (108) that may be a glass cover with an provided with a white diffusion coating or a plastic cover with a diffusion agent mixed within the material. A high-reflectance white material may be used to improve the light efficiency.
