Abstract: A light distribution control apparatus which is less affected by an error in a navigation function, and conducts a proper light distribution. An illuminated area and a glare quantity are controlled according to a determination on a traveling region of a vehicle (an expressway, a general road, or an urban region), and an illuminating direction is controlled according to a determination on a road shape. On the other hand, a navigation processor determines reliabilities of current position detection, and a vehicle position based on road data, and determines a reliability of the road shape and a reliability of the traveling region. A base illuminated area and a medium glare are selected when the reliability of the traveling region is low, an illuminated area according to the traveling region is selected and the glare quantity is decreased when the reliability is medium, and an illuminated area and a glare quantity according to the traveling region are selected when the reliability is high.

Abstract: The present invention accurately detects the illumination on the surface of an instrument panel, to thereby enable an easy view of the instruments. A meter unit includes an instrument panel in which a speedometer and other instruments are arranged, and an information display panel for displaying various information by characters and other graphic symbols. The instrument panel has a translucent dial, on the back side of which illuminating lamps are installed. A light sensor is located in the speedometer adjacent to indicators which display various kinds of information. Since the actual illumination on the instrument panel can be accurately detected in accordance with a result of detection by the light sensor, the luminance of the illuminating lamp can be controlled on the basis of the result of the detection, to thereby provide proper illumination for the rider's easy view of the instruments.

Abstract: Light for backlight to illuminate an LCD is irregularly reflected on a reflection plate. Part of the light leaks from the reflection plate to a rear surface side thereof. An aspherical lens collects the leakage light. Optical fibers guide the collected light to an object to be illuminated. The leakage light which inevitably leaks from the reflection plate and which has been wasted can be efficiently used. It is also advantageous to positively increase the leakage light such that the quantity of leakage light thus obtained is more than that of the leakage light inevitably appearing in a natural condition. Since the extension of the optical fibers is of side irregular reflection type, light sources can be provided at arbitrary locations thereof By efficiently using light for the backlight, the user's operating section can be illuminated while completely minimizing power consumption. The leakage part of light for the backlight from the irregular reflection plate can be efficiently used.
