  • Method for forming complex ceramic shapes
    Publication number: 20040168470
    Abstract: A method for forming single element arc tubes is provided. The method includes the use of the lost foam process in combination with ceramic forming processes. First, a polymeric material (20) is formed to define the internal dimensions. The outer dimensions are established with an external mold (40), followed by filling the mold with a suspension (60) that hardens. The outer mold is removed and the part is debindered to melt and remove the inner foam shape, followed by sintering to form a substantially transparent ceramic arc tube (70).

  • Discharge lamp with vented reflector
    Patent number: 6759794
    Abstract: A high intensity discharge lamp assembly (10) has improved thermal venting. The discharge light source (12) is housed within a reflector body (20). Recesses (40) are circumferentially spaced around an open end (28) of the reflector body. A containment structure (50, 50′, 50″) provides a structure that serves the containment function without interfering with the thermal venting.

  • Suspension adhesive for bonding and sealing components in a light source
    Patent number: 6531209
    Abstract: A suspension adhesive comprised of a matrix material and a particulate filler material is useful for bonding, sealing, repairing, and modifying ceramic, glass, and powdered metal components in a light source. A method for making the suspension adhesive includes the selection of a filler material and a volume percentage of the filler material. Additionally, a matrix material is selected and the filler material is dispersed throughout the matrix material. The suspension adhesive is used to bond and seal components to form, for example, an arc tube for a light source.
