摘要： What is described is are two techniques to improve the efficiency of a lamp, one being energy recycling and the second being linear polarization recycling both of which can be implemented singularly or together in an incandescent or gas discharge lamp outputting an improved illumination and/or linear polarized illumination at a improved efficiency; the linear polarized lamp being desirable for use in an LCD projector and other applications requiring linear polarized illumination. The lamp utilizes one or more wasted energy recycling techniques. One technique is use of reflective polarization filter over the exit aperture that reflects wasted polarization back to the surface of the reflector wherein the polarization is partially randomized by the dielectric reflective coating on the lamp reflector for recycling and redirecting the polarized radiation back to the exit aperture; another technique is to place a candoluminescent material in proximity of the filament, housed in a transparent envelope, to intercept the wasted radiation and be heated to output desirable illumination via candoluminescence.The processes described herein with the lamp reflector and the discriminative filters act as an energy trap, allowing only the desirable polarization and/or wavelengths to escape while the recycled polarization is randomized internal to the energy trap, and the wasted wavelengths are used to heat the candoluminescent material internal to the energy trap with the candoluminescent material acting as a secondary luminescence source.
摘要翻译：描述的是提高灯的效率的两种技术，一种是能量循环，另一种是线性极化回收，两者都可以在输出改进的照明和/或线性的白炽灯或气体放电灯中单独或一起实现提高效率的偏振照明; 线性偏振灯是期望用于LCD投影仪和其它需要线性偏振照明的应用。该灯采用一种或多种浪费的能量回收技术。一种技术是在出射孔上使用反射偏振滤光器，其将浪费的偏振反射回反射器的表面，其中偏振被灯反射器上的介电反射涂层部分地随机化，用于再循环并将偏振辐射重定向到出射孔 ; 另一种技术是将烛光发光材料放置在灯丝附近，容纳在透明的外壳中，以拦截浪费的辐射，并通过烛光发光加热以产生理想的照明。本文所述的具有灯反射器和鉴别滤光器的过程用作能量阱，仅允许所需的偏振和/或波长逸出，同时将再循环的偏振随机化在能量陷阱的内部，并且浪费的波长用于加热能量陷阱内部具有作为二次发光源的发光材料的发光材料。

摘要： An LED light source device can have a simple configuration which can easily create a desired light distribution pattern with a low profile and light weight. An illumination apparatus and a vehicle lighting device can also be configured to use the LED light source device. The light source device can include a light guide plate made of a flat plate-like material that is transparent in the visible range, and which has a front surface serving as a light emission surface. A point light source can be opposed to an end surface of the light guide plate. A rear surface of the light guide plate can include a luminance control element configured to control a luminance distribution on the light emission surface. The luminance control element controls light from the light source, incident through the end surface of the light guide plate, so that a reduced inversion of a light distribution pattern that is to be emitted is formed on the light emission surface as the luminance distribution. The light guide plate can include a polarizing film for making the light emission surface emit p-polarized (parallel polarized) light.

摘要： A visibility-enhancing system includes an adjustment mechanism for adjusting the polarization of a light source relative to the polarization of a viewing filter, so as to provide adjustable control of visual contrast between interposing media and an object to be viewed. The light source includes a light generation mechanism for generating polarized light, and an optional source polarization angle determination mechanism for adjusting the angle of polarization of the light source. The viewing filter includes a filter polarization angle adjustment mechanism for adjusting at least one of the polarization angle of maximum light attenuation and the polarization angle of minimum light attenuation. An observer adjusts at least one of the source polarization angle determination mechanism and the filter polarization angle adjustment mechanism so as to improve the visibility of the object to be viewed in the presence of interposing media.

摘要： An improved assembly for projecting polarized light uses a concave reflecting polarizer which is confocal with a concave metal reflector having a light source at its focus. Light possessing a preferred polarization azimuth is transmitted by the polarizer. Light possessing the orthogonal polarization azimuth is reflected back by the polarizer and circulates between the reflector and the polarizer. Its polarization is altered slightly by reflection from the metal. A small fraction, related to the degree of alteration, is transmitted by the polarizer. After several traverses a significant portion of the orthogonal polarization component is altered and transmitted through the polarizer.
