Lenses and bezels for lamps provide an appealing aesthetic look in the form of a colored glow at the edges of the lens or bezel by incorportation of an photoluminescent material in a molded polycarbonate body. The lenses are particularly suitable for use as an automotive outer lens, and can also improve the quality of the light emitted through this outer lens by interacting with the light bulb. The emitted beam is of a legal color and intensity as defined per the SAE J578 standard. The lighting performance may also be improved in such manner as reducing glare, increasing brightness or producing a beam that enhances road visibility at night to the human eye.
摘要:
Lenses for lamps can improve the quality of the light emitted through lens by interacting with the light bulb. Photoluminescent dyes as well as non-photoluminescent dyes may be incorporated into a polycarbonate lens in order to shift the chromaticity of the light source. Further, design features such as grooves or protrusions may be incorporated into the lens to allow light produced by the photoluminescent material to escape the lens and be added to the emitted beam to further shift the chromaticity. The emitted beam is of a legal color and intensity as defined per the SAEJ578 and SAEJ1383 standards. The lighting performance may also be improved in such manner as reducing discomfort glare, increasing brightness or producing a beam that enhances road visibility at night to the human eye.

A lighting device (RH) for a vehicle includes multiple light emitting devices (10, 20). Each light emitting device (10, 20) is constructed of a light emitting diode (11, 21) as a light source and a light guide lens (13, 23) for guiding light emitted from the light emitting diode (11, 21). The light emitting devices (10, 20) are formed in convex light emitting devices (10) and fan-shaped light emitting devices (20). The convex devices (10) and the fan-shaped devices (20) have different light distribution characteristics. Therefore, light distribution areas and intensity of the lighting device (RH) are more flexibly adjusted than other lighting devices using light emitting diodes as a light source.

An exterior light unit (2) for an aircraft or other vehicle, such as a road vehicle, ship or rail car, has an LED (4) in operation emitting light; a reflector (6), which reflects a first portion of the light emitted by the LED (4); a first lens (10), through which the first portion of the light is refracted after being reflected by the reflector (6); and a second lens (8), which is an aspherical collimating lens and which is arranged in such a way with respect to the LED (4) that a second portion of the light emitted by the LED (4) has an unobstructed path to the second lens (8) and is collimated by the second lens (8) in a main light output plane (16). The second portion of the light, when on its way from the LED (4) to the second lens, crosses way with the first portion of the light, when on its way from the reflector (6) to the first lens (10).

A vehicular lamp (10) includes a light source (14,15); a light guide (16) that guides the light from the light source (14,15); and a reflector (23-28). The light guide (16) includes an incident portion (32,33) to which light from the light source (14,15) is incident, wherein light entering from the incident portion is guided through the light guide (16); and a plurality of reflection portions (17-22) that internally reflect a portion of the guided light toward the reflector (23-28). The reflector (23-28) reflect, in a lamp illumination direction, reflection light that is emitted from the light guide (16) following internal reflection by the plurality of reflection portions (17-22).
