A light bulb that is suitable for use in conjunction with night vision equipment has an incandescent filament enclosed in a glass envelope that transmits substantially no detectable amount of light of a wave length greater than 700 nanometers.

Light bulb with glass envelope having light transmission of a wavelength

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.

A miniature two or three cell flashlight as disclosed to comprise a barrel, a tailcap, a head assembly, and means for holding a miniature lamp bulb and for providing interruptible electrical coupling to dry cell batteries retained within the barrel and having a recharger for charging the chargeable batteries via conductors in the tailcap.

A miniature incandescent lamp assembly has an elongated substantially cylindrical glass envelope having a first end and a second end. A substantially cylindrical first metal end member seals the first end of the glass envelope with a seal of substantially cylindrical configuration where the glass of the envelope is in glass-to-metal contact with the first metal end member. A substantially cylindrical second metal end member seals the second end of the glass envelope with another seal of substantially cylindrical configuration. In this seal also, the glass of the envelope is in glass-to-metal contact with the second metal end member. An incandescent filament is disposed between the first and second metal end members within the interior of the glass envelope in electrical contact with the first and second metal end members. Each of the first and second metal end members has a metal cap attached to the outside of the glass envelope, with the metal caps being larger in diameter than the glass envelope. The metal caps serve as a surface mountable electric contacts for the miniature incandescent lamp.

A miniature two or three cell flashlight as disclosed to comprise a barrel, a tailcap, a head assembly, and means for holding a miniature lamp bulb and for providing interruptible electrical coupling to dry cell batteries retained within the barrel and having a charger for recharging the chargeable batteries via conductors in the tailcap.

A flashlight reflector assembly including the substantially parabolic reflector having on one surface a reflectorized material, having a hole through its center as its converging end, and a plurality of support ribs extending from the backside of the reflector wherein a stainless steel heat shield is press fit into the back side of the reflector for protecting the reflector from over temperature conditions by reflecting heat back into the lamp and by conducting heat away from the converting portion of the reflector outward to the plurality of pins located behind the reflector reflecting surface.
