Abstract: A signal indicator lamp assembly (10) for a vehicle (14) has an LED assembly (16) that emits electromagnetic radiation (20), which is visible light, such as white light, that is composed of at least two wavelengths. A collimating optic (18) is positioned forwardly of the LED assembly (16) for providing substantially parallel light rays of the emitted radiation (20). A second optic (22) is positioned forwardly of the collimating optic (18), the second optic (22) having a first planar surface (33) facing the collimating optic (18) and a second, outer surface (35), the first planar, surface (33) having an interference coating (24) thereon, the interference coating (24) reflecting back toward the LED assembly (16) at least some of the first wavelengths (31) of the radiation (20) and transmitting at least some of the second wavelengths (39).
Abstract: An electrical contact (100) for a lamp (10) that includes electrical lead-ins (20) projecting away from a longitudinal lamp axis (40), said electrical contact (100) has a first electrically conductive segment (110) including a first segment (120) leading to a first reentrant portion (130), a first beam (140) that extends from the first reentrant portion (130) to an electrical lead-in engager (150), and a second reentrant portion (160) that connects to a second beam (170) that at least partially extends over the electrical lead-in engager (150). A back-up spring (220) is provided having a configuration substantially conforming to the conductive segment (110).
Abstract: An adjustable lamp holder has a mounting structure arrayed about a longitudinal axis. A pair of hollow pivot pillars extends from the mounting structure parallel to the longitudinal axis and a receptacle is positioned on the mounting structure parallel to the longitudinal axis and substantially opposite the pivot pillars. A body with a body axis coaxial with the longitudinal axis has a pair of pivots formed thereon for engaging the pivot pillars. A projection is formed on the body substantially opposite the pivots and an angle adjuster, having a proximal end and a distal end, has the proximal end positioned in the projection and the distal end positioned in the receptacle. Movement of the angle adjuster tips the angle of the lamp.

Abstract: A direct view LED lamp (10) comprising: a heat sink body (12) having a longitudinal axis (14) and a wall (16) having an exterior (18) and an interior (20). A cavity (22) is formed in the interior (20) and is defined by a circumferential side wall (24) and a back wall (26). A circuit board (28) is positioned in the cavity (22) adjacent the back wall (26). At least one LED (30) is mounted on the circuit board (28) facing in an axial direction parallel to the longitudinal axis (14) and away from the circuit board (28). An optical light guide (32) is positioned adjacent the at least one LED (30). A housing (42) spans the cavity (22) and has a coupling face (44) to mate with the heat sink body (12).
Abstract: An integral HID reflector lamp may be formed with an HID held in a reflector. An inner element is mechanically coupled to the reflector. The inner element is formed with a first mechanical coupling to mate with the reflector, a second mechanical coupling to mate with a circuit board, and an electrical coupling to at least electrically couple one of the leads to the circuit board. A circuit board has an edge mechanically coupled to the inner element and electrically connected to the leads by an electrical coupling on the inner element. A heat sink spans at least one side of the circuit board and forming an EMI shielding. An outer cover encloses the heat sink, circuit board, and inner element and coupled to the assembly of the reflector, HID lamp, inner element, and heat sink with each elements of the assembly clipped together.
Abstract: A lamp (10), which can be used in rapid thermal processing (RTP), has a lamp envelope (12) arrayed along a longitudinal axis (14) and has a top (16) and a bottom (18). A first coiled-coil filament (20) having a first lead-in (20a) and a second coiled-coil filament (22) having a second lead-in (22a), are parallelly arrayed to each other and to the longitudinal axis (14) within the envelope (12). A serial connector (24) joins the first and second filaments; and an electrically insulating support (26) is positioned near the bottom (18) of the lamp envelope (12). The first lead-in (20a), the second lead-in (22a) and at least a portion (24a) of the serial connector (24) are sealed within the insulating support 26 whereby the first and second lead-ins (20a, 22a) and the at least a portion (24a) of the serial connector (24) provide the only support for the first and second filaments (20, 22).

Abstract: An LED lamp assembly with a substantial heat sink may be inexpensively constructed using sections of extruded metal as the heat sink. The extruded heat sink sections are trapped in latched sandwich structure assuring good thermal contact between the LED light sources and the extruded heat sink and a metal optic. The inexpensive structure may be rapidly assembled.

Abstract: A robust LED lamp may be assembly by forming a heat sinking sandwich with two metal heat sinks positioned around the circuit board and pinned together a heat conductive element. The assembly is positioned by pressing it into a base providing electrical connections. The robust assembly is rapidly assembled, thermally effective in draining or spreading heat from the circuit board and is readily adaptable to a variety of applications lighting. The heat sink may be decorated, colored or otherwise esthetically enhanced for consumer appreciation.
