Illuminating device
First Claim
1. An illuminating device, comprising:
- an essentially flat, transparent illuminating housing including a front side, a rear surface and a circumferential side wall;
a plurality of light emitting elements supported by said housing along said circumferential side wall;
a reflecting layer provided in said housing on said rear surface thereof and along said circumferential sidewall, said reflective layer reflecting inwardly with respect to said housing; and
, light collimating projection means including a front element in the form of one of a convex lens or an element with raised parts or recesses for projecting, and collimating light reflected by said reflecting layer and generated by said light emitting element.

Abstract
An illuminating or light emitting device for use as a headlamp, a signaling lamp or other lamp for shining light in a beam or otherwise. It comprises as its main parts a generally flat transparent illuminating element with a circumferential edge in which a plurality of light emitting elements such as LED'"'"'s are set. The edges are provided with an inwardly reflecting layer. The front side of the illuminating element is in the form of a light radiating surface, while the rear side is completely covered with an inwardly reflecting layer. Such an illuminating device may have a very flat overall shape, has a low current requirement and has a large homogeneous radiating area. It more especially lends itself to use on vehicles.

10. A light projector for illuminating distant objects, comprising:
- a substantially flat transparent housing including a rear surface, circumferential side wall and a front lip;
a light radiating surface provided on an interior side of said rear surface, circumferential side wall and said front lip for reflecting light inwardly from each of said rear surface, said circumferential side wall and said front lip;
a plurality of light emitting diodes supported by said circumferential side wall and distributed substantially uniformly along said circumferential side wall, said lip extending outwardly from said side wall a distance which is greater than the distance said light emitting diodes extend from said circumferential side wall;
light collimating means including a conical lens connected to said lip at a front side of said housing for focusing light, reflected by said light radiating surface, outwardly from said housing in a direction substantially perpendicular to said back wall.
- a substantially flat transparent housing including a rear surface, circumferential side wall and a front lip;
