Abstract

549,226. Electric lamps. BRITISH THOMSONHOUSTON CO., Ltd. March 26, 1942, No. 4003. Convention date, March 28, 1941. [Classes 39 (ii) and 75 (iv] In an automobile or other light projecting lamp comprising an air-tight enclosure having an electric lamp bulb sealed within it, penetration of air into the enclosure through the bonding cement 35 securing the bulb 25 to the lamp base shell 24 is prevented by providing an additional seal 36 of non-porous material. The bonding cement 35 may consist of an inorganic filler such as powder of marble, alumina, or magnesia mixed with a binding agent such as shellac, rosin and synthetic resins. The sealing material 36 may be a vinyl resin of the thermoplastic type with or without a suitable filler or a thermo-setting material such as urea formaldehyde, phenol formaldehyde, phenol furfural or a mixture of such gums, an alkyl resin being preferably added to prevent brittleness. The lamp shown consists of metal reflector 11 and a glass or other lens 12 secured together with an interposed rubber gasket 15 by pressing the flange 16 of the reflector over the rim 14 of the lens. The reflector is formed with a central opening 19 in which the shell 24 is secured by solder 23. The lamp bulb 22 may be similar to that described in Specification 545,103. The sealing material 36 may be enclosed between the lamp bulb and the shell, the outer edge of which may be flared.
