Abstract: A UV-emitting phosphor blend is provided which comprises a mixture of at least two UVA-emitting phosphors selected from SrB4O7:Eu, YPO4:Ce, and BaSi2O5:Pb wherein the sum of the weight percentages of the phosphors in the mixture equals 100%. The phosphor blend may additionally contain an amount of SrCe0.08MgAl11O18 in an amount from 0 to 12 wt. % of the mixture. Tanning lamps containing these blends exhibit increases in initial UVA output and UVA maintenance.

Abstract: A connecting pin (10) for an anode contact (11) (shown more completely in FIG. 2). The pin (10) has a body (12) with a longitudinal axis (14). A contact head (16) is formed at a proximal portion of the body (12) and a base (18) is formed at a distal portion of body (12). An intermediate shank (20) connects the head (16) and the base (18). The head (16), base (18) and intermediate shank (20) are all symmetrically arrayed about the longitudinal axis (14). The shank (20) has a first diameter (D,) and the contact head (16) has at least one lateral dimension (D2) that is greater than the shank diameter (D). The base (18) has a diameter (D3) that is greater than the shank diameter (D) and has a surface (22) that is planar and substantially orthogonal to the longitudinal axis (14).

Abstract: A ceramic arc tube assembly and a method for making a ceramic arc tube are described which simplify the manufacture of ceramic arc tubes by reducing the number of handling and heat treatments required to assemble arc tubes prior to the final sintering operation. In particular, the invention uses transient assembly buttons during intermediate assembly steps which are removed prior to the final sintering operation.

Abstract: A discharge device for operation in a gas at a prescribed pressure includes a cathode having a plurality of micro hollows therein, and an anode spaced from the cathode. Each of the micro hollows has dimensions selected to produce a micro hollow discharge at the prescribed pressure. Preferably, each of the micro hollows has a cross-sectional dimension that is on the order of the mean free path of electrons in the gas. Electrical energy is coupled to the cathode and the anode at a voltage and current for producing micro hollow discharges in each of the micro hollows in the cathode. The discharge device may include a discharge chamber for maintaining the prescribed pressure. A dielectric layer may be disposed on the cathode when the spacing between the cathode and the anode is greater than about the mean free path of electrons in the gas. Applications of the discharge device include fluorescent lamps, excimer lamps, flat fluorescent light sources, miniature gas lasers, electron sources and ion sources.
