Linear diffuse light source

Claim 1

A light source for producing a relatively uniform dispersed light emission along a length portion thereof, comprising: a prism having two ends, an emission face and a plurality of optically reflective planar faces, formed of optionally transparent material having a relatively high index of refraction and shaped to capture light emitted longitudinally therein said emission face and said reflective planar faces forming a hexagonal cross-section and said reflective faces forming right angle prism sides adjacent said emission face; light emitting diodes disposed at the ends of said prisms to emit light longitudinally in said prism so as to be captured therein; and said prism having an optically transparent and light dispersing frosted window formed in said emission face along a length of the emission face thereof, said window linearly narrowing toward the ends of said prism so as to emit through said window light captured in said prism as it is emitted from said light emitting means in a dispersed, longitudinally uniform way.
