Abstract: 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).

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: 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: 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).

The first member (16) has a closed end (16a) and a connecting end (16b) and the second member has two connecting ends (18a 18b). At least one intermediate member (24) has at least one light source (20) and a male connecting end (24a) and a female connecting end (24b). At least one flexible joining member (26) is also provided, the flexible joining member being capable of bending at least 90° and being joinable to any of the first and second end members and the intermediate members.

Abstract: An LED and light guide assembly has an LED with an output surface; a first power input lead electrically coupled to a first pole and having a first surface and a second surface; and a second power input lead electrically coupled to a second pole and having a first surface and a second surface. A unitary, molded light guide has an axially extending, light transmissive body with a light output window. An input window is formed with the unitary, molded light guide being aligned in a zero-gap relationship to capture substantially all the light emitted by the LED. A support is formed integral with the light guide and envelopes a portion of the first surface and the second surface of the first power input lead and the first surface and the second surface of the second power input lead to anchor the guide with respect to the power inputs.
