In a device for directing light longitudinally forwardly, the combination comprises a light source; a drum lens having a body extending about the light source, for refracting light from the source; a light reflector extending about the drum lens body for forwardly re-directing refracted light received from the drum lens body, the drum lens and reflector defining a longitudinally forwardly extending optical axis; and including an aspheric lens located longitudinally forwardly of the light source to refract light received from a source to be transmitted in a forward direction.

Light collimating and distributing apparatus

In a device for directing light longitudinally forwardly, the combination comprising a light source, and a protective, transparent envelope extending about the light source; a drum lens having a body extending about the light source and envelope, for refracting light from the source; a light reflector extending about the drum lens body, for forwardly and convergently re-directing refracted light received from the drum lens body; and a correcting lens for receiving a collimating re-directed light screened from the reflector.

Screen illumination apparatus and method

A device for directing light longitudinally forwardly, that comprises a lens body having a front face facing forwardly, rearward body extent, and a curved sidewall extending between the rearward body extent and the front face; a rear cavity in the body, the cavity having a sidewall and a front wall defining a corner; and a light source in the cavity, and characterized in that light rays transmitted by the light source toward the curved sidewall, and toward the corner are collimated forwardly.
