ABSTRACT:
The present invention relates to a lens for use with a lamp having at least one LED light source. The lens preferably includes a plurality of projections each having a substantially flat top surface and a plurality of sloping side surfaces, preferably suitable for dispersing the emitted light. Such a variance in light emission may enhance the light being viewed from different angles and positions therefrom.
