CONFIGURABLE LUMINAIRES AND COMPONENTS
A steerable illumination fixture includes an emitting source and a refractive optical system that steers an emitted beam by relative translation of the emitting source against the optical system. The light emitting source may be placed along an optical axis of one or more lenses to produce an output beam along that axis, or translated in-plane (orthogonal to the optical axis) relative to the lenses to produce a steered beam. The optical system may include refractive lenses or mixing channels and/or one or more baffles with apertures. A round, uniform beam results that retains approximately the same power level and beam width as it is steered. A second lens having a diameter equal to or larger than a first lens may be provided and configured with an effective focal plane of the two lenses located approximately at the plane of the light emitting source.
VEHICLE LAMP
There is provided a vehicle lamp including a projection lens, a first light source arranged at a rear of the projection lens and configured to emit light for forming a predetermined light distribution pattern, a reflector configured to reflect the light emitted from the first light source towards the projection lens, a first array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row, and a second array light source arranged at the rear of the projection lens and including a plurality of semiconductor light emitting elements aligned in at least one row. The first array light source and the second array light source are arranged in an upper-lower direction.
POLYESTER COMPOSITION AND ARTICLE PREPARED THEREFROM
A composition includes 100 parts by weight of poly(alkylene terephthalate) and 0.01 to 2 part by weight of a compound represented by Formula (1), a partially saponified derivative thereof, or a combination thereof, (1) wherein R.sup.1, R.sup.2, and n are defined herein. The composition, which excludes copolymers of an unsubstituted or substituted styrene and an unsaturated nitrile, is useful for molding articles with very smooth surfaces. For example, the composition can be used to mold directly-metallizable substrates for automotive headlight reflectors and bezels.

LED LIGHT SOURCE FOR VEHICLE-MOUNTED HEADLIGHT
This LED light source for a vehicle-mounted headlight is provided with: a blue LED that emits blue light having a dominant wavelength of 430-470 nm; and a fluorescent material that is arranged forward in the light emission direction of the blue light and that performs wavelength conversion of the blue light. The main fluorescent material constituting the fluorescent material is a celium-activated lutetium/aluminum/garnet fluorescent material represented by Lu.sub.3Al.sub.5O.sub.12:Ce. The LED light source for a vehicle-mounted headlight emits pseudo-white light that has a color temperature of 6,000 K or less and that is unlikely to decrease in visibility even during bad weather. The LED light source for a vehicle-mounted headlight has characteristics such as a wide lighting range and excellent visibility in the peripheral area of the visual field (the peripheral visual field) and can thus contribute to accident prevention and road traffic safety.
ILLUMINATION MODULE AND HEAD LIGHT
A beam pattern module includes a heatsink base, at least one LED light and light reflector housing. The heatsink base includes a base frame and at least one at least one chip mounting surface. The chip mounting surface protrudes on an inner side surface of a base plate of the heatsink base, and the LED light is disposed on the chip mounting surface. The light reflector housing includes a side portion and a reflecting portion. The side portion is provided with a one cut-out. The side portion is fitted on the inner side surface, and the chip mounting surface and the LED light are exposed in the mounting space. The reflecting portion extending from an edge of the side portion and coupled to a rear plate of the base frame, so as to form a single module to be installed to a vehicle light device.

VEHICLE LAMP
A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.
VEHICLE LAMP
Provided is a vehicle lamp including an operation unit configured to operate an optical axis adjustment bevel gear provided in a lamp to be axially rotated. An axial rotation force transfer body of the operation unit includes an operation rod operated to be axially rotated, a driving rod engaged with the gear, and a wire interconnecting the operation rod and the driving rod in an axial rotation direction, and the driving rod is formed of a metal which is hard to rust. The driving rod is formed by a metal/injection/molding (MIM) technique. A support member extends between the driving rod and the lamp.
