  • Electrodeless lamp
    Patent number: 6856092
    Abstract: A lamp 1 has a body 2 of sintered alumina ceramic material and an artificial sapphire window 3. The body 2 is initially molded in green state and the window is pressed into a front recess 4. The combination is fired at a temperature of the order of 1500° C., to fuse the body into a coherent pressure-tight state with the window. After partial cooling to the order of 600° C., a pellet of excitable material is added through a rear, charging aperture 5. A disc 6 of ceramic with frit 7 is placed over the aperture. The disc is irradiated by laser to fuse the frit and the disc to the body, thus sealing the excitable material into the lamp.

  • Method for manufacturing an electrodeless lamp
    Patent number: 6666739
    Abstract: The lamp consists of a hollow tubular body 1 with a closed end 2 and an open end 3. The body is of sintered ceramic material. A window 4 is sealed across the open end, the window and the body being united by a layer of frit 5. The window is of sapphire. Within the body is sealed an inert gas atmosphere 6 and a pellet charge of excitable material 7. In use, the lamp is subjected to RF electromagnetic radiation which heats it to 1000° C. causes it to emit visible light via the sapphire.
