#CMT# #/CMT# The device has a windscreen (8) as projection surface, and a collective lens system (2) for coupling of surrounding light (1). A diffuser device (3), a mirror (4), a beam splitter and lenses (10) are provided for controlling of the surrounding light together with the light of an artificial light source (5) on a display (6). The diffuser device is present for homogenization of the surrounding light and/or the light of the artificial light source. The beam splitter is present for overlapping of the surrounding light and the light of the artificial light source. #CMT#USE : #/CMT# Projection device i.e. head-up- display, for use in a motor vehicle and aircraft. #CMT#ADVANTAGE : #/CMT# The collective lens system is provided for coupling of the surrounding light, and the diffuser device, the mirror, the beam splitter and the lenses are provided for controlling of the surrounding light together with the light of the artificial light source on the display, thus enabling high-contrast image even in unfavorable lighting conditions of the surrounding, and hence reducing the lost heat caused by the artificial light source and increasing the life span and the efficiency of the LED light sources. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating a structure of a projection device using coaxial radiation guidance. 1 : Surrounding light 2 : Collective lens system 3 : Diffuser device 4 : Mirror 5 : Artificial light source 6 : Display 8 : Windscreen 10 : Lenses. |
