  • Patent number: 7851981
    Abstract: Ornamental light strings are commonly made of a plurality of miniature light bulbs connected together, often in series, to make a light string. This invention is directed to optimizing the perceived brightness while reducing heat in each bulb. This is a particular problem where resistor bypass circuits are used where a bypass resistor being connected in parallel with at least one of the respective light sources, each respective light source being low wattage and being capable operating on a one hundred percent duty cycle as desired. Improvements are accomplished by changes in placement of the filament, its windings and materials.

  • Publication number: 20100133981
    Abstract: A lamp (10), which can be used in rapid thermal processing (RTP), has a lamp envelope (12) arrayed along a longitudinal axis (14) and has a top (16) and a bottom (18). A first coiled-coil filament (20) having a first lead-in (20a) and a second coiled-coil filament (22) having a second lead-in (22a), are parallelly arrayed to each other and to the longitudinal axis (14) within the envelope (12). A serial connector (24) joins the first and second filaments; and an electrically insulating support (26) is positioned near the bottom (18) of the lamp envelope (12). The first lead-in (20a), the second lead-in (22a) and at least a portion (24a) of the serial connector (24) are sealed within the insulating support 26 whereby the first and second lead-ins (20a, 22a) and the at least a portion (24a) of the serial connector (24) provide the only support for the first and second filaments (20, 22).

  • Patent number: 7576480
    Abstract: The present invention relates to an electrical incandescent lamp (1), in particular a halogen incandescent lamp, in which luminous element limbs (14, 16) extend in lamp vessel structural parts (42, 44), the lamp vessel structural parts surrounding the luminous element limbs in sections at a distance, and the axes of the lamp vessel structural parts (42, 44) extending at a distance from one another in order to increase the energy efficiency of the incandescent lamp, in particular if a layer (42a, 44a) which reflects IR radiation is applied to the lamp vessel structural parts. When using the pinch-sealing technology, it is possible to achieve a small system voltage halogen lamp having a long life expectancy and at the same time requiring little energy for reaching the operating temperature.

  • Publication number: 20090108726
    Abstract: An infrared light source has a filament fabricated on a first substrate in the shape of a microbridge and energizes the filament so as to generate heat, thereby causing the filament to emit infrared radiation. The infrared light source has a second substrate that is bonded to the first substrate and seals the filament, and feedthrough electrodes that lead electrodes of the filament to the outside of the first substrate. Thereby, the function of the package is imparted to the device itself, to thus realize a highly-reliable device at low cost.
