Abstract: A light-emitting device operating on a high drive voltage and a small drive current. LEDs (1) are two-dimensionally formed on an insulating substrate (10) of e.g., sapphire monolithically and connected in series to form an LED array. Two such LED arrays are connected to electrodes (32) in inverse parallel. Air-bridge wiring (28) is formed between the LEDs (1) and between the LEDs (1) and electrodes (32). The LED arrays are arranged zigzag to form a plurality of LEDs (1) to produce a high drive voltage and a small drive current. Two LED arrays are connected in inverse parallel, and therefore an AC power supply can be used as the power supply.

Abstract: A light bar has several modular light source heads which may contain different types of light sources as well as different technologies mounted in cages by shock absorbing grommets. The cages are mounted on a bottom member so that the heads can be arranged along opposite sides and the ends of the bottom members. The heads are captured, and assembled with the bottom member, by a top member which also captures translucent or transparent members or lenses along the sides of the light bar and, transparent or translucent end caps which may also provide lenses for the light source heads at the ends of the bar. The end caps are removably connected to the top and bottom members at the ends of the bar by screws extending through the end caps. The light source modules have the same wiring connected thereto by connectors from a connector board to connectors along the back ends of the light source heads.

Abstract: A lighting system with removable light modules mounted on a frame by an attractive force between magnetic material of the light module and magnetic material of the frame such that a light module may be installed on, removed from, or relocated on the frame manually without tools or permanent electrical connection. The frame may be one-, two-, or three-dimensional, and it may provide an aesthetic appearance even when the lighting system is not illuminated. The light modules may employ incandescent, quartz-halogen, LED, or fluorescent light sources. Particularly, in LED embodiments, the magnetic materials serve the dual functions of mounting and heat sinking. The lighting system may be utilized as a sign, signaling device, or a building block in larger lighting systems. The lighting system has a wide variety of applications and provides a user with improved ability to control the quantity, direction, and characteristics of the emitted light.
