A lamp and epitaxial processing apparatus are described herein. In one example, the lamp includes a bulb, a filament, and a plurality of filament supports disposed in spaced-apart relation to the filament, each of the filament supports having a hook support and a hook. The hook includes a connector configured to fasten the hook to the hook support, a first vertical portion extending from the connector toward the filament, and a rounded portion extending from an end of the first vertical portion distal from the connector and configured to wrap around the filament. A second vertical portion extends from an end of the rounded portion distal from the first vertical portion and the second vertical portion has a length between 60% and 100% of the length of the first vertical portion.

An arrangement of linear heat lamps is provided which allows for localized control of temperature nonuniformities in a substrate during semiconductor processing. A reactor includes a substrate holder positioned between a top array and a bottom array of linear heat lamps. At least one lamp of the arrays includes a filament having a varying density and power output along the length of the lamp. In particular, at least one lamp of the arrays includes a filament having a higher filament winding density within a central portion of the lamp relative to peripheral portions of the lamp. In some embodiments, the at least one lamp is a central lamp extending across a central portion of the substrate heated by the lamp. Furthermore, at least one lamp of the arrays has a higher power output within a central portion of the lamp than at peripheral portions of the lamp.

An image pickup unit includes: a printed wiring board provided with an image pickup element and having a first electrode on a surface layer; a flexible wiring substrate having a base member having first and second faces, a conductive layer provided on the first face, and an insulating layer provided on the conductive layer, wherein the conductive layer has a second electrode in which the insulating layer is not provided to one longitudinal end part; a conductive connection member that connects the first electrode to the second electrode; and a reinforcement member provided on the base member on the second face side, wherein the reinforcement member continuously covers an end part of the insulating layer on a side closer to the second electrode and an end part of the conductive connection member on a side closer to the insulating layer of a portion connected to the second electrode.

The invention relates to a headlight for a vehicle, comprising a concave reflector and a lamp arranged within the reflector to reflect light from the lamp to create an illumination beam with a bright/dark boundary. The lamp comprises a transparent vessel including a longitudinal axis, at least a first and second filament arranged within the vessel. A baffle arranged proximate to the first filament, and comprising first and second upper side edges. The first filament is arranged above a plane including the upper side edges. A different plane is through the center of the first filament and is arranged perpendicular to the longitudinal axis. The upper side edges are arranged symmetrically to a baffle symmetry axis extending from the center of the first filament centrally between the upper side edges. The lamp is arranged within the reflector rotated around said longitudinal axis by a rotation angle of 2-20.

An infrared heater includes a heater body and a casing. The heater body includes a heating element and a metamaterial structure capable of emitting infrared radiation having a peak wavelength of a non-Planck distribution when thermal energy is supplied from the heating element. The casing has an interior space in which the heater body is disposed and whose pressure is reducible. In addition, the casing includes an infrared radiation transmitting portion capable of transmitting the infrared radiation emitted by the metamaterial structure to an outside of the casing.

An infrared emitter that comprises a cladding tube made of quartz glass that surrounds a heating filament as an infrared radiation-emitting element that is connected via current feedthroughs to an electrical connector outside the cladding tube. To improve the service life and power density, the heating filament comprises a carrier plate with a surface made of an electrically insulating material, whereby the surface is covered by a printed conductor made of a material that generates heat when current flows through it.
