摘要:
A vehicle headlamp system having optical reflector, lamp capsule, and gasket is disclosed. The vehicle headlamp system uses surfaces formed as part of the optical surface yielding located light source. As a result, the light source is more accurately positioned with respect to the reflector, and a more accurate beam pattern is formed. The lamp capsule is assisted in its location by a spring to force the capsule in proper location. The headlamp system no longer uses an O-ring to provide location, but an improved flat resilient gasket provides a sealing and locking force to maintain proper face to face coupling. The preferred lamp capsule uses a cup to shield light reflected from the press seal. The preferred lamp capsule uses a cup, and pedestal system mounting providing five axes of light source positioning. The preferred lamp capsule uses a clip coupling to join the light source holder to the plastic base.
摘要:
A lamp capsule for use in a vehicle headlamp includes a lamp envelope having a tubular portion. First and second spaced-apart filaments are mounted in the lamp envelope for emitting light when energized by electrical energy. The lamp capsule further includes one or more light-attenuating axial stripes on the lamp envelope. The axial stripes are positioned on the lamp envelope for blocking light emitted by the first filament and reflected by the second filament. The lamp capsule may further include light-attenuating rings at or near opposite ends of the lamp envelope for defining upper and lower boundaries of a clear region of the lamp envelope. A filament support structure may include support leads located in the plane of the filaments for limiting light blockage and stray reflections.

Traditional methods of making headlamp coils have left a portion of the coils with slightly irregular forms. These irregularities can result in defects in the ultimate beam pattern. Accommodating these defects in robust lamp and headlamp optical systems can reduce the performance that might otherwise be available. The preferred coil is therefore continuously coiled as a straight body, and carefully cut into segments. Subsequently, legs are welded to the coil segment ends. The coil is then left substantially undistorted by the manufacturing process that would otherwise normally leave a portion of the coils distorted. The method particularly enables a functional center leg coil.

A waterproof portable lamp (10) comprises a housing (12); a light source (14) including a plurality of LEDs, a power supply (16) for said light source (14) and a switch (18) for energizing said light source (14) contained within said housing (12). An opening (20) is formed in said housing (12) permitting egress of light when said light source (14) is energized. A flexible, transparent cover (22) is peripherally sealed to said opening (20) in a watertight manner and a switch activator (24) is substantially centrally located on and fixed to said flexible, transparent cover (22). The lamp (10) is activated be depressing the center of the flexible cover (22), which moves the switch activator (24) into contact with the switch (18).

A lamp (10) has a housing (12) with a base (14) with an internal circumferential wall (16) arranged about a longitudinal axis (18). A hollow body (20) projects from the housing (12) and is symmetrically arrayed about the longitudinal axis (18). A light guide (21) is positioned in the hollow body (20) and as a single output end (22) arrayed along the longitudinal axis (18) and has a plurality of radially extending arms (23), each of the arms having an input end (24). The light guide (21) is preferably constructed from a molded acrylic or a suitable glass having wave-guide characteristics.

An LED lamp having a support with a metal substrate and a center portion with projecting wings. An electrically insulating, thermally conductive circuit is affixed to the substrate; and at least one LED is positioned on each wing with electrically conductive traces connected thereto. The center portion is planar. The wings are bent at multiple angles forming legs, a first angle being greater than 90 degrees, a second angle being normal to the planar center portion. The preferred center portion is pentagonal. The bulb cooperates with a socket that comprises a base; a hollow pedestal extending from the base, the pedestal having a polygonal interior; a thermally conductive, core having an exterior matching the interior; a gap between interior walls of the interior and exterior walls; and a plurality of electrical contacts positioned in the gap for contacting the traces when the bulb is inserted in the socket.
摘要:
An LED lamp and a method of making an LED lamp in which the lamp includes a heat conductive post with slots in an exterior of the post, and in which a separate LED assembly is inserted into each of the slots, where each of the LED assemblies has a substrate with an LED at a first end thereof, which is inserted into the slot first, and an electrical conductor that extends from the LED to a second end of the substrate. The electrical conductor is connected to a circuit board that is inside a hollow bottom of the post. A reflector and heat sink are attached to the bottom of the post.
摘要:
A lamp capsule with lug connectors, having a lamp bulb, a holder, and a lug is disclosed. The lamp capsule lead extends through the holder passage to fit closely with the lug foot. The lug foot is then rotary swaged to the lamp lead. The swaging mechanically and electrically seals the lead and the lug. An interference coupling is exactly formed along the lead by the swaging, so the lead and lug are precisely located and cannot move with reference to one another. The lug and lead are then tightly held and located with reference to the holder. The mechanical interference fit also forms an electrical connection that cannot separate like a cold weld. The swaging may additionally remove any excess exterior extension of the lead. As a result, the lug is quickly, accurately, and permanently coupled to the lamp lead, and holder preventing subsequent loosening or displacement that may effect lamp positioning or connection durability.
