Abstract: A method and an apparatus for regulating the brightness of a light source (2), configured as an incandescent lamp, in the illumination beam path (8) of a microscope (1), the brightness of the light source (2) being modifiable by increasing or reducing the electrical power delivered to the light source (2), are characterized in that a red shift, associated with the reduction in the delivered electrical power, of the spectrum of the light emitted by the light source (2) in the illumination beam path (8) is compensated for by way of a variable optical filter (16) that brings about a blue shift of the spectrum. A color-neutral regulation of the brightness of the illuminating light is thereby achieved.

Abstract: Due to an effect of a solenoid of a moving mechanism, when a valve and a shutter are positioned at a first position, a light source is positioned at a first light source position and a shutter is in a state of closing a window. A lighting luminous flux from a light source is reflected by a reflector so as to be irradiated as a first light distribution pattern. Thus, a part of the lighting luminous flux is introduced to the reflector from the open window. Therefore, it is possible to effectively utilize the lighting luminous flux emitted from one valve in correspondence to a light distribution pattern.

Abstract: Disclosed herein is a vehicle headlight equipped with a gas-discharge lamp, which is designed such that a high beam mode or a low beam mode is selectively operated by controlling a position of the gas-discharge lamp using a magnetic force, thus making the interior construction of the headlight compact, in addition to the prevention of frequent malfunction of the headlight. The headlight is provided with a lamp control means controlling a position of a bobbin in a housing to selectively operate the low beam mode or the high beam mode. The lamp control means includes a return spring provided in the housing to elastically bias the bobbin forward. A magnet assembly is installed in a rear portion of the housing in such a way as to be adjacent to a rear end of the bobbin. A solenoid is wound around a rear portion of the bobbin and cooperates with the magnet assembly to move the bobbin and a bulb rearward when electric power is applied.

The movable reflector comprises a bore at the center of the reflector for receiving a bulb assembly and retention features integrally molded on the rear side of the reflector to retain the bulb assembly.

Abstract: When the vehicle body rolls to the oncoming lane, a light source bulb is turned to a direction opposite to a rolling direction to keep the posture of the light source bulb in an erect state. Accordingly, a horizontal cut-off line CL1 of a low-beam light distribution pattern P is prevented from slanting downward to the oncoming lane side. A horizontal cut-off line forming area 20a1 of a reflector 20 is formed with a plurality of reflection elements 20s1a and 20s1b and the like. Those elements are formed extending from the upper end to the lower end and slanting, at an angle of 5°, downward to the optical axis Ax1 with respect to the vertical direction. As a result, when the vehicle body rolls to the oncoming lane side, the reflection elements 20s1a and 20s1b and the like are substantially orthogonal to a light-dark borderline L1 formed by an inner shade 18c of the light source bulb, to thereby sharpen the horizontal cut-off line.

Abstract: The improved vehicle headlight has both leveling device and beam switching device which drives bulb displacing mechanism to displace light source bulb relative to reflector along its optical axis. In addition to driving the bulb displacing mechanism to displace the light source bulb relatively in a determined amount, actuator of the leveling device is driven to tilt the reflector through a determined angle, whereby a low beam is switched to a high beam and vice versa. Compared to the conventional system that performs beam switching by merely driving the bulb displacing mechanism, the vehicle headlight enables the same bulb displacing mechanism to displace the light source bulb through simple relative movements.

Abstract: A magnetic field controller has been developed, which allows magnetic deflection of the arc of an alternating current high intensity discharge (HID) lamp. The controller consists of a driving circuit and an electromagnet. The system delivers a fast switching magnetic field, which can follow the alternating current signal of an alternating current HID ballast. The method minimizes the electromagnet's inductance and uses fast reacting ferromagnetic materials (Ni--Zn ferrite). To achieve the required magnetic field, a current amplifier was developed to pick up the signal from the alternating current ballast and drive the electromagnet with up to two amperes. The alternating magnetically deflected HID lamp system allows the use of magnetic deflection for alternating current HID lamps. A vehicle headlamp system can achieve multiple beam functions (day light running, low beam and high beam) of a headlight system with only one alternating current lamp.

Abstract: The efficiency of a horizontally operated arc discharge lamp has been found to be substantially improved by the application of a transverse magnetic field. The magnetic field moves the arc downward, away from the upper wall of the lamp envelope. The magnetic field moves the arc so that the outer mantel that otherwise would make contact with side walls of the envelope stand away from the envelope wall. With the arc withdrawn from the wall, less energy is lost in heating the envelope, resulting in more energy be directed to the emission of light.

Abstract: An automobile headlight including a single movable light source which does not change the angle of its optical axis relative to the optical axis of the reflector. The light source is coupled to an apparatus capable of changing the position of the light source depending on the driving state of the automobile. The headlight has sufficient light distribution patterns for multiple driving conditions, such as when the automobile is traveling straight ahead, by-passing another vehicle, or carrying a heavy load, without changing the angle of the optical axis of the light source relative to the optical axis of the reflector. This allows the driver to maintain good visibility while prolonging the life of the headlight and reducing its overall size.

Abstract: The present invention provides a a headlight operable as a running light of a vehicle and, in particular, as a headlight of the vehicle for selectively projecting a low and a high beam. The headlight includes a reflector having a light source disposed therein. A beam position adjusting device operates to move the light source between its low beam position and its high beam position. The beam position adjusting device includes an electric powered drive motor and a displaceable interconnecting element interconnecting the beam position adjusting device and the light source. The device also includes a motion translation element for translating the drive output of the drive motor to displacement of the displaceable interconnecting element, the beam position adjusting device being operable to dispose the light source in its high beam position. A return movement device automatically biases the light source to move to its low beam disposition when the drive motor is not powered.
