  • Patent number: 4489367
    Abstract: Headlight comprises a hollow metal housing with a circular rim defining a forward opening. A side outlet socket assembly is provided in the housing, at the rearward end, to receive the transverse pins of a side-pin style bulb. The housing rim has external threads on the outside and a conical, tapered surface on the inside. A separate bulb and lens retainer ring has an external conical, tapered surface, sealingly engageable with the conical surface in the housing rim to provide a tapered flame path in the event of an internal explosion and also allows easy removal of the bulb and lens. The bulb and lens retainer ring has an inner bore with counterbores at the front and rear ends. A rubberlike ring in the rear counterbore provides an elastic seat for a flange on the front of the bulb and cushions it against shock. A heavy lens is potted by epoxy, or otherwise permanently sealed into the front counterbore.

    Abstract: Safety lamp apparatus, suitable for use as a miner's cap lamp, includes a housing body closed at one side by a plastic light transmitting member. A bulb member is yieldably received in the housing body and is operable, when energized, to provide a filament in a state of incandescence for emitting visible radiation. During use of the apparatus in an explosive atmosphere conditions may arise where deformation of the light transmitting member from external impact forces directed thereagainst may drive deformed portions of the light transmitting member against the bulb member with sufficient force to cause bulb breakage and resulting explosion of the atmosphere.In the present invention protective means is provided comprising an arrangement of parts defining an oblique angular relationship between the central longitudinal axis of the bulb member and the impacting surface of the deformed portion of the light transmitting member.

  • Patent number: 4197574
    Abstract: A device for protecting a light emitting bulb such as an ordinary light bulb from impact and rain. The device includes a substantially cylindrical body which is closed at one end. A neck is formed through the closed end to accommodate a light socket and the body defines a cavity to enclose a light bulb positioned in the socket. Holes extend through the closed end of the body adjacent the cylindrical wall. The holes extend upwardly in tubes above the surface of the closed end. A circular flange extends inwardly from the closed end into the cavity. This flange is larger in diameter than the bulb to be placed within the cavity; and it extends to a knife edge. The outer extremity of each hole through the closed end is aligned with the inner surface of the substantially cylindrical wall while the inner extremity of each hole is aligned with the outer surface of the flange.

  • Patent number: 4176391
    Abstract: A shock isolating lamp assembly for a vehicle lamp including an improved shock isolating mounting is provided. The assembly includes a lamp housing for receiving a lens and a shock isolating mount of a resilient material including a central body portion formed with a vertical opening for receiving a lamp socket and two opposed pairs of parallel arms symmetrical to the center line extending outwardly from the body in a plane. The arms are spaced apart a distance approximately the diameter of the lamp socket. Each pair of arms is joined to a perpendicular mounting bar of the same resilient material which cooperates with a pair of opposed mounting tracks extending into the lamp housing. The lamp socket is substantially tubular, open at the top and bottom end and formed with a pair of opposed barbs for engagement by a pair of opposed recesses formed in the inner wall of the mount body portion for retaining the socket therein.

  • Patent number: 4171499
    Abstract: To permit economical attachment of a socket end to the press of a lamp, the socket is made of a deformable synthetic plastic material, for example Teflon PFA, the socket having concentric cylindrical surfaces and being of cup shape, and the lamp press having rectangular cross section, the socket being heated to softening temperature and the lamp press to melting temperature of the socket material and then inserted into the cup-shaped socket to permit instantaneous melting andflowing of the socket material around the edges of the rectangular press, and thus seat the socket on the press end. The socket is preferably preheated in a metal mold block, and the press by a flame directed towards the end press of the lamp from a side remote from that of the electrical connection to the lead-through of the press.

  • Patent number: 4150422
    Abstract: An armored light projector is provided, having a linear light source arranged at the focal axis of a reflector unit capable of projecting a light beam of parallel rays having a substantially rectangular cross-section, the light source being mounted in a rear bottom recess of the reflector unit such as not to be directly visible from the front of the projector. The recess within which the light source is mounted is shielded by an armor assembly against direct impact of a projectile aimed at the front or at the sides of the projector. The projector has shock-absorbing suspension means capable of supporting the linear light source and affording means allowing its connection to a suitable external electric power supply. Means may be provided for protecting the rear and the top of the reflector unit against shocks and or blows, and means may be also provided for improving the cooling of the projector.

  • Patent number: 4133528
    Abstract: In a translucent play ball, an improvement of apparatus for illuminating the play ball utilizes batteries and a lamp. The apparatus includes three compressible helical springs and a translucent casing for encapsulating the batteries, lamp and springs. The springs are compressed within the casing in contact with one another. The lamp is secured to an end of the middle spring, which also encircles the batteries. The spring to the side away from the lamp holds the batteries in contact with the lamp and itself contacts the batteries. A series circuit is thus completed through the batteries to the springs and back to the lamp. In modified forms, the casing has removable and locking end caps and a switch for switching off the lamp by decompressing the springs.

  • Patent number: 4104711
    Abstract: An airport light fixture is designed to withstand the severe vibrations and high wind velocity encountered in the take-off and landing operations of jet aircraft. The light fixture includes a pedestal and lamp base provided with spherical portions of different curvature which engage only at peripheral mating surfaces. When the lamp base and pedestal are clamped together, e.g., by a set of bolts, considerable pressure is exerted between the spherical portions to hold the pedestal and lamp base in firm engagement at the peripheral mating surfaces. In addition, the light fixture includes an improved lens mounting arrangement to firmly secure its lens on the lamp base and yet permit the lens to be conveniently removed for repair of the light fixture.
