Optical unit for e.g. passenger car, has screen placed between lens and one light source of turn signal/reversing lamp, and guiding part of light emitted by source towards reflector linked with another source of turn signal/reversing lamp

摘要

#CMT# #/CMT# The unit has turn signal and reversing lamps (20, 40) with light sources (22, 42) such as LED, held by classical units (24, 44) in openings (26, 46) of reflectors (28, 48), respectively, and a transparent lens (14) shielding the unit. The light emitted by the sources and reflected by the reflectors is focused for forming light beam emitted in illumination ranges (32, 52) via the lens. A screen (60) is placed between the lens and one light source, and guides a part of the light emitted by the light source towards one reflector associated with the other light source. #CMT#USE : #/CMT# Used for a motor vehicle e.g. passenger car, to provide turn signal lamp function, reversing function, stop function, side marker light function, and fog light function. #CMT#ADVANTAGE : #/CMT# The screen guides the part of light emitted by one light source towards the reflector associated with another light source, thus increasing the perceptible illumination zone for a given lighting function. The transparent lens shields the optical unit, thus protecting the components of the lamps from external environment such as from dust, gravel and rain. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top sectional view of an optical unit. 10 : Optical unit 14 : Transparent lens 20 : Turn signal lamp 22, 42 : Light sources 24, 44 : Classical units 26, 46 : Openings 28, 48 : Reflectors 32, 52 : Illumination ranges 40 : Reversing lamp 60 : Screen.
