OMNI-DIRECTIONAL LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/147103
Kind Code:
A1
Abstract:
An omni-directional light emitting device includes a substrate (11) and a plurality of LED light sources (12) disposed on the substrate (11). A light guiding lampshade (13) for refracting and reflecting light rays emitted by the LED light sources (12) is disposed above the substrate (11). The light rays emitted by the LED light sources (12) are refracted and reflected by the light guiding lampshade (13), so that the light rays radiate all around and thus the illumination range of the LED light sources (12) is considerably increased.
