摘要： A light emitting device is produced using one or more light emitting diodes within a light mixing cavity formed by surrounding sidewalls. The light emitting device includes a light adjustment member that is movable to alter the shape or color of the light produced by the light emitting device. For example, the light adjustment member may alter the exposure of the wavelength converting area to the light emitted that is emitted by the light emitting diode in the light mixing cavity. Alternatively, the height of a lens may be adjusted to change the width of the beam produced. Alternatively, a movable substrate with areas of different wavelength converting materials may adjustably cover the output port of the light mixing cavity to alter the color point of the light produced.

摘要： The present invention relates to a headlight for motor vehicles, which comprises an appropriate casing (4), by means of which a so-called surface directing reflector (5) is completely surrounded; said reflector is preferably an oval-shaped one and is capable to withstand a characteristic thermal flux density P > 0,6 W/cm 2 and is moreover furnished with a thin reflecting layer on the basis of aluminium, and wherein said casing also comprises a transparent glass (3) consisting of appropriate material on the basis of minerals or polymers, and also a bulb (1) with integrated filament (2), which is used as a light source and is placed in the central position of said reflector (5). According to the invention, the ratio between the distance of the reflector (5) from the filament (2) of the bulb (1) and the thermal flux density should be greater than 17 mm cm 2 /W. Still further, the wall of said reflector (5) in the area above the bulb (1) and between each available connecting means (71, 72), by which said reflector (5) is connected to each position adjusting means, is essentially reduced with respect to the wall in any other area of said reflector (5).

摘要： A reflector reflects incident light and comprises crystalline plastic in which a crystal region and an amorphous region are mixed, wherein the amorphous region includes a plurality of orientation layers comprising amorphous particles that are oriented in a predetermined direction. The reflector, which has high reflectance, is formed by extending a crystalline plastic material exhibiting a superior extensibility to extend the amorphous particles in the amorphous region in the predetermined direction so as to form a plurality of extension layers in the amorphous region. Since a reflector having a superior performance with a very improved reflectance can be provided due to a high diffuse reflectance by the extension layers in the amorphous region without a foaming process or an additional additive to increase the reflectance, the manufacturing process of the reflector is simplified and the manufacturing cost is reduced so that productivity can be greatly improved.

摘要： The present invention provides a lighting system with a color indicator surface (24, 30). The surface receives light via a cover (18) of the lighting system, mainly through internal reflection. Hence, the light from the light sources, here at least two different colored LEDs (14), is guided away from the main light emitting surface (20), such that well-mixed light with a lower intensity may be used to determine the color of the light. The color indicator surface may be a surface (24) of the cover (18), or may be a surface (30) of a separate outer part (26). The lighting system may be used to illuminate objects in houses, shops and so on. The color indicator surface provides a convenient and easily accessible color reference.
