摘要

#CMT# #/CMT# The lamp has a light source (1) associated to a reflector (2) reflecting the light in a direction of a screen (4) that is formed of a set of passive catadioptric patterns (5). Light passages (6) are formed between the patterns and permit free passing of the light issued from the source across the screen. The reflector has optical units (3) for ensuring the focusing of the light towards the passages provided between the patterns. An auxiliary screen is disposed between the reflector and the screen. #CMT#USE : #/CMT# Used for motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The lamp eliminates the need for an intermediate focusing screen, while facilitating the fabrication of the lamp and reducing the cost of the lamp. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a signal lamp. 1 : Light source 2 : Reflector 3 : Optical units 4 : Screen 5 : Passive catadioptric patterns 6 : Light passages.
