    摘要： A dimming circuit for an indicator switch has a control input, a dimming state and a non-dimming state. The dimming circuit is responsive to the presence of a backlight PWM signal at the control input of the dimming circuit to switch to the dimming state and responsive to the absence of the backlight PWM signal at the control input of the dimming circuit to switch to the non-dimming state. In the dimming state a high resistance of the dimming circuit is coupled in series with the indicator LED and a LED drive output of the function control module and in the non-dimming state a low resistance of the dimming circuit is coupled in series with the indicator LED and the LED drive output of the function control module. The high resistance has a resistance higher than the low resistance.

    摘要： A display apparatus (100), e.g. for a vehicle dashboard or console, includes illumination means such as backlight (112) for illuminating a display screen (110) via which information, e.g. satellite navigation information or vehicle operational data or video content, is visibly displayable to a viewer under variable conditions of incoming incident light, wherein the apparatus (100) comprises: detecting means (115, 121) for detecting light or other electromagnetic radiationincident on the apparatus (100); and control means (190) for controlling the illumination means (112) in dependence on the incident light detected by the detecting means (121); wherein the detecting means (115, 121) comprises directional detecting means (115, 121), e.g. including a plurality of light-sensitive devices (121) and a waveguide (115) or collimator device, for detecting a direction from which the light is incident thereon, and the control means (190) is operable to control the illumination means (112) in dependence on the detected direction of incidence of the incident light.

    摘要： An information device for use with an engine of a vehicle includes lighting means (27, 28) for providing information about a power position of the vehicle, engine running detection means (70, 71) for detecting engine running, gear shift position detection means (60, 61) for detecting gear shift position, and illuminance control means (20) for controlling illuminance of said lighting means (27, 28). The illuminance control means is operable so that, when a detection is made by the engine running detection means (70, 71) that the engine is running and by the gear shift position detection means (60, 61) that the gear shift position is other than in a P range or N range, the illuminance control means (20) reduces the illuminance of the lighting means (27, 28) compared with the illuminance of the lighting means (27, 28) when the gear shift position is in the P range or N range. In a further aspect the information means (20) comprises vehicle speed detection means (81) for detecting vehicle speed, wherein the illuminance control means (20) is operable to alter the illuminance of the lighting means (27, 28) in response to the detected vehicle speed.

    摘要： The invention relates to a display device (1) which provides a user with additional information by changing colour. Said display device comprises a display (2) or display instruments that are illuminated by differently coloured light sources. Driving parameters are detected by sensors (13, 14, 15, 16, 17, 18) and the colour of illumination is selected according to said driving parameters.

    摘要： An optical emergency indication system for motor vehicles has LEDs (22) associated with PDLC liquid crystal diffusors (24) for the most important indicator lamps. When one of these lamps is switched on the diffusor (24) is simultaneously energized and, for a predetermined time, the LED (22) emits a flash of light spread over a solid angle which is certain to intersect the driver's field of vision; when this time has elapsed, the light emitted by the lamp returns to its nominal value.
