    Abstract: A subminiature incandescent lamp has a substantially cylindrical base to which a glass envelope enclosing the interior of the lamp is sealed. A pair of contact wires or pins are made of a metal alloy that has substantially the same thermal expansion coefficient as the glass base. The contact pins are embedded and sealed to the glass base in a gas-tight manner, with a glass-to-metal seal. The contact pins extend below the base to provide external connections of the lamp to a power source. The pins also extend into the interior of the lamp, and provide electrical contact to a filament which is mounted between them. A filament support wire is anchored in the glass base at one end thereof and has a loop at its other end in which the mid-section of the filament rests and is mechanically supported.

    Abstract: A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope wherein a filament is contained in contact with metal members having glass-to-metal seals with the glass envelope. A substantial portion of the outer surface of the glass envelope is coated with a light reflective metal coating, with a non-coated elongated window transparent to light being left on the surface. The metal members extend axially to the outside from the envelope and, when mounted to a circuit board provide electric contact for the lamp. At least one of the end members includes a unique surface feature, such as a flat portion of an otherwise cylindrical surface, which is directionally coupled relative to the window of the glass envelope and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window disposed in the desired direction.

    Abstract: A miniature or subminiature incandescent lamp designed to operate with an energy source of 20 volts or less includes a filament enclosed in a first glass envelope and supported by a pair of metal contact pins. A first glass bead seals the envelope and has a pair of openings through which the metal contact pins penetrate and wherein they are hermetically sealed. A second glass bead of low melting solder glass is larger than the first bead and is sealed below the first bead and extends circumferentially beyond the perimeter of the first bead. A third bead of high melting glass is disposed below the second bead also in sealing relationship with the second bead. The outside perimeter of the third bead is substantially co-extensive with that of the second bead. A second glass envelope is sealed to the outside perimeter of the second bead and is also in abutting relationship with the third bead. The interior of the first envelope is evacuated or contains an inert gas of the type normally used in incandescent lamps. The interior hermetically sealed space between the first and second envelopes is also evacuated, filled with an inert gas or with nitrogen. The resulting miniature and subminiature lamps have operating exterior surface temperatures which do not exceed 160° C.

    Abstract: A subminiature incandescent lamp has a substantially cylindrical base (24) to which a glass envelope (22) enclosing the interior of the lamp is sealed. A pair of contact wires (26) or pins are made of a metal alloy that has substantially the same thermal expansion coefficient as the glass base. The contact pins are embedded and sealed to the glass base in a gas-tight manner, with a glass-to-metal seal. The contact pins extend below the base to provide external connections of the lamp to a power source. The pins also extend into the interior of the lamp, and provide electrical contact to a filament which is mounted between them. A filament support wire (20) is anchored in the glass base at one end (30) thereof and has a loop (34) at its other end in which the mid-section of the filament rests and is mechanically supported.

    Abstract: A surface mountable miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope (20) wherein a filament (22) is contained in contact with metal members (26) and (36) having glass-to-metal seals with the glass envelope (20). A substantial portion of the outer surface of the glass envelope (20) is coated with a light reflective metal coating (50), with a non-coated elongated window (52) transparent to light being left on the surface. The metal members (26) and (36) extend axially to the outside from the envelope and, when mounted to a circuit board provide electric contact for the lamp. At least one of the end members includes a unique surface feature, such as a flat portion (54) of an otherwise cylindrical surface, which is directionally coupled relative to the window (52) of the glass envelope (20) and which acts as a key or indexing surface for mounting the lamp assembly to the receiving surface (circuit board) with the window (52) disposed in the desired direction.
