Claims (10)

A light source, a reflector with a non-circular hole, and a lamp with a matching and distributing lens corresponding to the reflector hole, wherein at least one outer portion of the reflector is cut to form a hole, and at least the inner portion is circular around a common optical axis. Arranged in a symmetrical fashion, the shape of the parts being: (a) at least one inner part of the light reflecting the emanation of the distant field of view; Arrayed lamps. The lamp of claim 1 wherein the lamp is at one inner part and two outer parts of the reflector. 3. The method of claim 2, wherein the innermost portion of the reflector produces a far field divergence with a half angle of about 3 degrees in the case of a small light source, with the half angle of about 20 degrees depending on where the light strikes the reflector. The lamp which produces distant view divergence that is -2 degrees, and the outer part of the reflector produces the vision divergence which is approximately 0 degrees -20 degrees distant The lamp of claim 1 wherein the lens has a side flange with an array of refracting prisms positioned in the cutout of the reflector and acting to distribute the light transversely. 5. The prism arrangement as set forth in claim 4, wherein the prism arrangement is inclined at an increasing angle with respect to the light from the light source and consists of a series of nearly punctured surfaces on the inner surface of each flange connected to the engraving surfaces, each prism arrangement. Lamp is bent on its tip. A lamp, means for forming an optical axis in which a large part of the emitted light is densely distributed, and a prism and / or lens system formed close to the lamp of the means, one or more prisms adjacent to the edge of the lens system A light composed of a prism and / or lens system that blocks light and distributes its debt using global internal reflections through the material of the lens system, such that light appears above 100 ° from the edge to the optical axis. 7. The lamp of claim 6, wherein the prisms are arranged to block direct sunlight from the lamp. 8. The method of claim 7, wherein the min-incidence angle i _{min on} the plane of the prism where direct light from the lamp is refracted into the material is given by Sin i _min = n Sin [φ _c -θ], where n is The index of refraction, φ _c is the critical angle of the overall internal reflection, and θ is the angle between the angle of incidence and the plane on which the overall internal reflection occurs. 7. The lens system of claim 6, wherein the lens system is symmetrically convex over most of the light when viewed from the front of the light and the edge surrounding the majority is formed such that the scrap and dip faces meet at an obtuse angle. , A light whose dip surface receives incident light reflected from the inside. 7. The light of claim 6, wherein a plurality of said prisms are positioned adjacent said edge, and the shape of the edge where said light appears is blocked such that the light appears at an angle range. ※ Note: The disclosure is based on the initial application.
