摘要： A lamp-to-light guide coupling arrangement includes an electrodeless high intensity discharge lamp comprising an arc tube with an ionizable fill, and an excitation circuit for electrically exciting the ionizable fill to induce therein a light-producing arc discharge. The coupling arrangement further includes a coupling device comprising a generally tubular, hollow body that has an inlet end for receiving light from the arc discharge and a larger, outlet end. The coupling device further comprises an interiorly directed reflector on a surface of the hollow body for reflecting visible light. Such coupling device is shaped so as to receive light at one solid angle over an area of the inlet end and to transmit light at a smaller solid angle but over a larger area of the outlet end. The coupling device is preferably formed from dielectric material. The reflector preferably comprises a refractory optical interference filter.

摘要： An interference filter or coating is provided in a predetermined pattern on a lamp envelope. The coating is comprised of alternating layers of high and low index of refraction materials applied to a vitreous outer surface of a lamp envelope. The coating may be geometrically symmetric or asymmetric, continuous or discontinuous with respect to the coating itself or the envelope to which it has been applied. The envelope can be masked prior to deposition of the coating so that removal of the mask leaves the filter in the desired pattern. The preferred process for forming the coating includes forming a boric oxide mask on a portion of the envelope, applying the coating over the mask and removing the coating from masked areas of the envelope by dissolving the mask in an aqueous solution.

摘要： A light source includes an integral reflective coating on a portion of its envelope for reflecting light back through the source. The light from the source is directed by a reflector toward a focus thereof at which is located an input end of a light guide. The integral reflective coating allows a half ellipsoidal reflector to be used in one embodiment without depreciable loss of light. Accordingly, a pair of light sources can be arranged with a common focus to substantially double the brightness in the light guide. Alternatively, the light sources can provide a primary and redundant arrangement, or used to provide two levels of light in another arrangement. According to another embodiment, a hemispherical reflector is used to obtain unit magnification and increase the angular range through which light may enter the light guide.

摘要： An electric lamp includes a sealed outer envelope, an arctube located within the envelope, a shroud separate from the arctube having an ellipsoidally-shaped reflecting portion positioned around the arctube, and a coating disposed on the reflecting section of the shroud for reflecting light having predetermined wavelengths emitted by the arctube. The ellipsoidal shape of the shroud is effective for reflecting the light substantially back toward the arctube. Particularly when the coating is a color correcting coating, the shape of the reflecting section is tailored to maximize reflection of radiation at selected wavelengths back toward the arc of the arctube.

摘要： A metal halide arc tube is provided having a light-transmitting envelope and electrodes for generating an arc discharge within a sealed chamber of the envelope. The envelope includes a transparent film at a cold region of the sealed chamber where metal halides migrate and condense. The transparent film transmits visible radiation and absorbs ultraviolet radiation emitted by the arc to impose an additional heat load on the cold region so that a high metal halide vapor pressure can be maintained. The temperature of a hot region of the envelope can be maintained at a lower level by reducing power input or increasing chamber surface area. Preferably, the transparent film reflects infrared radiation emitted by the light source back to the arc to increase efficiency and further increase the temperature of the cold region due to decreased thermal emittance. The transparent film is preferably a dichroic coating having alternating layers of high and low index of refraction refractory materials.

摘要： Fused quartz containing both titanium dioxide and cerium oxide as UV absorbing dopants has been found to be particularly effective for lamp envelopes for high temperature lamps such as halogen-incandescent lamps and metal halide arc discharge lamps which emit both UV and visible light radiation. The codoped quartz transmits visible radiation and absorbs a substantial portion of the emitted UV radiation. The UV absorption is far superior at temperatures above 500.degree. C. and the codoped quartz does not react with the fill within.
