Abstract: A system includes a radiation source capable of emitting first light and a fluorescent material capable of absorbing the first light and emitting second light having a different wavelength than the first light. The fluorescent material is a phosphor having the formula (Lu1-x-y-a-bYxGdy)3(Al1-zGaz)5O12:CeaPrb wherein 0<x<1, 0<y<1, 0<z?0.1, 0<a?0.2 and 0<b?0.1. In some embodiments, the (Lu1-x-y-a-bYxGdy)3(Al1-zGaz)5O12:CeaPrb is combined with a second fluorescent material capable of emitting third light. The second fluorescent material may be a red-emitting phosphor, such that the combination of first, second, and third light emitted from the system appears white.

Abstract: There is provided a low pressure discharge lamp, which comprises a discharge tube, a lamp base holding the discharge tube, and a base cap (6) for covering the lamp base. The base cap (6) also provides mechanical support to the discharge tube. The base cap (6) comprises tube openings (10) for receiving end parts of the discharge tube. The base cap (6) further comprises an adhesive space (14) adjacent to a tube opening (10), the adhesive space containing an amount of adhesive. The adhesive space (14) is open toward the discharge tube. The adhesive contained in the adhesive space (14) adheres to an end part of the discharge tube and thereby fixes the discharge tube to the base cap (6). The base cap comprises at least one upper transversal member (31) and at least one lower transversal member (32). The transversal members (31,32) extend substantially in a plane parallel to a plane of the tube opening (10) adjacent to the adhesive space (14).

Abstract: A method of bonding spacers to an anode plate of a field emission display. An anode plate having separate phosphor regions is provided, wherein a black matrix material is provided to separate the phosphor regions from one another. A magnetic layer is formed on the black matrix material. A thin metal film is formed on the anode plate and the magnetic layer. Spacers are disposed on the metal film above the black matrix material. An electromagnetic induction procedure is performed to heat the magnetic layer and thus serves as a heating source to produce heat, wherein the heat goes through the metal film to heat the spacers. A direct current (D.C.) electric field procedure is performed to bond the spacers to the metal film above the black matrix material.
