Abstract: A lamp (10) has a light source (12) with a distal portion (14) and a proximal portion (16), the proximal portion (16) comprising a press seal (17) having a given cross-section. A lamp envelope (18) receives the light source (12), the envelope (18) being arrayed about a longitudinal axis (20) and having a base (22) generally orthogonal to the longitudinal axis (20). A clip-receiving aperture (24) is formed in the base (22), and at least one clip locator surface (26, 52, 54) is formed in the base (22) adjacent the clip-receiving aperture (24). A clip (28) is positioned in the clip-receiving aperture (24), the clip having a passage (29) shaped and formed to receive the press seal (17) of the light source (12) therein. The clip (28) has at least one first retainer (32) and at least one second retainer (33), the at least one first retainer (32) being shaped and formed to engage the at least one clip locator surface (26, 52, 54), whereby the clip (28) is located within the clip-receiving aperture (24).

Abstract: A lamp (10) has a cup-shaped body (12) with a planar bottom (14) with an up-standing, peripheral sidewall (16) defining a top (18). The body (12) is thermally conductive and preferably is a metal such as aluminum. A reflective coating (20) is provided on the inside surface of the planar bottom (14) and side wall (16) for reflecting light generated by a single, side emitting LED (22) that is mounted on a thermally conductive, electrically insulating coupling (24) and is positioned substantially in the center of the planar bottom (14). A lens (26) for directing a beam of light emitted from the LED (22) in a desired direction is provided and preferably is a Fresnel optic. The lens (26) can close the opening (18) as shown in FIG. 1 or it can be formed as an integral part of bottom (14) or it can be added to the bottom (14), as shown in FIG. 2. Alternatively, the lens (26) can be solid with the lens elements either external (FIG. 4) or internal (FIG. 5).

Abstract: A lamp assembly 10 has a housing 12 that preferably is non-rotationally symmetrical. In a particular embodiment the housing 12 can be rectangular; however, other non-rotationally symmetrical housings can also be employed. The housing 12 includes a base 14 and an upstanding wall 16 surrounding the base 14. The space between the cover 24 and the base 14 defines a light-conducting channel 34. A light-receiving aperture 36 is defined in the housing 12 and in one instance is formed to receive light from a light source 22. A first light-receiving conduit 38 is defined in the light-conducting channel 34 and is formed to receive light from the light source 22 that is fitted into the light-receiving aperture 36 and conduct light to a second light-receiving conduit 40 defined in the light-conducting channel 34.

Abstract: 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.

Abstract: An electronic housing assembly is formed with an environmental seal (20), EMI control (56) and a good thermal coupling (44, 46) made between enclosed hot electric components (48, 50) and an exterior heat sink (52, 54).

Abstract: An integrally ballasted lamp assembly (200) including a spacer disk (220) disposed in a lamp receptacle cavity (244) between a lamp (226) and the bottom (238) of the lamp receptacle (214). The disk (220) may be configured to contact connector clips (216, 218) coupled to the bottom (238) of the lamp receptacle to positively align the clips (216, 218) for connection to a ballast circuit disposed on a PCB (212). The disk (220) may also, or alternatively, at least partially occlude connector clip openings (402, 404) in the bottom (238) of the lamp receptacle (214) for hindering the flow of uncured cement (902) through the openings (402, 404), and may also, or alternatively, provide a thermal barrier between the lamp (226) and the lamp receptacle (214).

Abstract: A solid-state light source (10) comprising a plurality of LED units (12) arrayed to emit light generally about an axis (14). Each of the LED units (12) can comprise a number of LEDs, for example, up to five. They may all emit in a single color or multiple colors can be combined for a specific effect. A light transmissive light guide (16) is associated with the LED units (12) and has a plurality of input widows (18). Each LED unit (12) faces a respective input window (18) and each window (18) transversely intercepts the axis (14) and receives light from the LED units (12). The input windows (18) lead to a common output window (20) that is axially aligned with the input windows (18). The light guide (16) has smooth sidewalls (22) that extend between the input windows (18) and the output window (20).

Abstract: An more efficient or higher luminance LED assembly may be formed from a high power LED chip having a first surface, and a second surface, the first surface being mounted to a substrate; the second surface being in intimate thermal contact with a light transmissive heat sink having a thermal conductivity greater than 30 watts per meter-Kelvin. The LED chip is otherwise in electrical contact with at least a first electrical connection and a second electrical connection for powering the LED chip. Providing light transmissive heat sink can double the heat conduction from the LED dies thereby increasing life, or efficiency or luminance or a balance of the three.

Abstract: An arc discharge lamp (10) has an envelope (12) including a base (14) containing lead-ins (16, 18). An arc tube (20) is positioned within the envelope (12) and has electrodes (22, 24) sealed therein. The electrodes have connection ends (26, 28) extending outside of the arc tube (20). A flexible primary electrical connector (30) is fixed between one of the lead-ins (16) and one of the connection ends (26) of one of the electrodes (22), the flexible primary electrical connector (30) having an area “A” subject to intergranular corrosion in the presence of oxygen and arc tube operating temperatures. A rigid secondary, intergranular-corrosion-resistant electrical connector (32) is electrically connected between the lead-in (16) and the one of the connection ends (26) of the one of the electrodes (22), the rigid secondary electrical connector (32) by-passing the area “A” that is subject to intergranular corrosion.
