Abstract: A lighting device has a light-bar mount and multiple light bars. The light-bar mount is integrally formed from a board. The light bars are mounted on the light-bar mount and each light bar has a heat sink, a circuit board and multiple high-power LED modules. The heat sink is detachably mounted in the light-bar mount. The circuit board is mounted in the heat sink. The high-power LED modules are mounted on the heat sink and electrically connected to the circuit board for providing outward illumination.
Abstract: A side light type backlight includes a light source including a plurality of LEDs, and a light guide plate. One of the end surfaces of the light guide plate is a light incidence surface at which a plurality of R-LEDs, a plurality of G-LEDs and a plurality of B-LEDs are arranged. LEDs satisfy the relationship of: a distribution range of light emitted from G-LEDs<a distribution range of light emitted from R-LEDs, or a distribution range of light emitted from G-LEDs<a distribution range of light emitted from B-LEDs. Also, LEDs are electrically connected to each other.
Abstract: Lighting devices comprising first, second and third strings of solid state lighting devices. One aspect further comprises means for supplying first fixed current through the first string, means for supplying second fixed current through the second string, and means for supplying current through the third string. In a second aspect, the first and second strings emit light within a specific area on a 1931 CIE Chromaticity Diagram, and the third string emits light of dominant wavelength 600-640 nm. A third aspect further comprises a power line and a power supply configured to supply a first and second fixed currents through the first and second strings, respectively, and supply a current to the third string. A method of making a lighting device, comprising measuring color output, adjusting current to first, second and/or third strings, and permanently setting currents to the first and second strings.

Abstract: A decorative display apparatus having a front support member and a rear support member held parallel to each other by at least one stabilization body. The front support member may comprise one or more first apertures and the rear support member may comprise an equal number of second apertures axially aligned with the respective first apertures. In a preferred embodiment, illumination housings extending through the first and second apertures may comprise recyclable items to provide an environmentally friendly alternative for decorative displays. The front and rear support members may further comprise either two or more components removably connected to each other and/or one or more fold lines thereby allowing for compact storage when not in use. The present invention may further comprise lights disposed within the illumination housings, creative artistic embellishments, and features allowing consumers to hang decorative items from the components of the decorative display apparatus.
Abstract: The invention relates to an operational lamp comprising at least one light source that is situated in a lamp body and an optical element, which is designed to direct the visible radiation of the light source onto an operational field. According to the invention, said lamp comprises several light emitting diodes as the light sources.
Abstract: A Light-Emitting Diode (“LED”) light includes a ring-shaped housing wish a cross section, a transparent section and a non-transparent section. The ring-shaped housing defines a horizontal plane relative to a midpoint of the cross section, and a board is fitted within the ring-shaped housing at an angle between about ten to sixty degrees relative to the horizontal plane with LEDs mounted thereon the board to emit light through the transparent section. In one aspect, the board is a printed circuit board. In one aspect, the LEDs are mounted approximately perpendicularly onto the board.
