Abstract: A bicycle light system has front and rear (white and red) lights with mounting brackets to secure on a bicycle helmet. A rechargeable battery is contained in the rear light casing, with an electrical cord extending between the front and rear light casings. The front light casing has controls for both front and rear lights, which can include different power levels and preferably a flash mode for the front light. 360° visibility preferably is provided via the front light, which projects colored light, such as amber, toward the sides. In a preferred embodiment the battery is rechargeable using a micro USB connection, a serial bus configuration widely used for cell phones, so that the battery will ordinarily be rechargeable via a cell phone recharging cable or a connection to a computer. Helmet mountings for the front and rear light casings have a quick-release feature enabling the lights to be easily and quickly removed from the helmet, such as for recharging.

Abstract: A light and sensor assembly (22) for use with a land craft, watercraft or aircraft. The assembly includes a shell (28) for mounting to, or that is a part of the body (24) of, the vehicle. Internal to the enclosed space defined by the shell is a socket and bulb assembly (30, 32) for providing light and heat. Also disposed in the shell is a transducer (36) that emits or receives energy as part of a proximity sensing assembly. The transducer is encased in a transducer housing (38). The transducer housing is positioned relatively close to the bulb so that the heat emitted by the bulb warms the transducer housing. This heat fosters the evaporation of water off the exposed face of the transducer housing so as to minimize the extent to which this water can inhibit the utility of the transducer.

Abstract: A lamp (10, 30, 80) includes an LED module (16, 36, 86) having at least one LED (12, 32, 82) arranged on a substrate (14, 34, 84). An optical system includes at least one lens (18, 38, 88) in optical communication with the LED module (16, 36, 86). A zoom apparatus (20, 40, 90) selectively adjusts the relative axial separation of the optical system and the LED module (16, 36, 86). In one embodiment (30), the zoom apparatus (40) is slidably adjustable. In a another embodiment (80), the zoom apparatus (90) is rotatably adjustable.

Abstract: A device used as a toy or novelty item has a handle and one or more LEDs that are powered by a stepper motor that is configured to operate as a generator. The stepper motor is embedded within a protective housing element and is rotatably connected with the handle. The housing element extends from the handle and rotates with the stepper motor about the hand-held handle to generate electric current. The LEDs are electrically connected to the stepper motor and extend along the housing element. The device may be used as a hand-held toy so that the LEDs illuminate when the element is twirled or spun relative to the handle. The device may also be used as the handle of a jump rope. When the jump rope is twirled or spun between the handles, the stepper motors generate current which illuminates the LEDs to create an entertaining effect.

Abstract: A lighting assembly for improving the performance of undercabinet and streamlined lighting includes a LED module onto which is mounted a plurality of light emitting diodes (LEDs). The LEDs serve as the light source for generating a light pattern. An optical assembly focuses and disperses the LED output to a desired light contour. The lighting assembly further includes a mounting base for attaching the LED module to an associated surface, such as the underside of a cabinet. A battery source is optionally enclosed in the module for providing primary or secondary power to the lighting assembly. In a preferred embodiment, the battery source is a rechargeable battery that can be recharged by means of an AC adapter that connects to the lighting assembly.

The first to third lens array units are sequentially arranged from the light source side. The image-side focal point of the combined system of lens portions of the first and second lens array units is located at the third lens array unit. The object-side focal point of the combined system of lens portions of the second and third lens array units is located at the first lens array unit, thereby attaining a reduction in the size of the illumination apparatus.
