  • Patent number: 9468060
    Abstract: An embodiment of the present invention provides a retrofit LED lamp that is operated by a dual mode circuit, enabling maximum compatibility with the ANSI reference ballasts to satisfy UL requirements to replace HID and fluorescent lamps. The LED lamp operates at two different modes, offered by the dual mode PCB circuit. In one of the mode, namely ANSI ballast testing, a low frequency current from the ballast is throttled through a bypass circuit to LEDs, since a field effect transistor of the circuit is in open circuit mode due to insufficient current. During the second mode, namely field ballast operation, a high frequency current is provided by the ballast, which short circuits the FET, causing it to conduct and thus operating the LEDs. Advantageously, the LED lamp offers maximum compatibility with ballasts using such dual mode circuit and consumes less power.

The LED modules can interface with one another via one or more connectors, which allow two or more LED modules to be electrically and mechanically coupled together. The connectors may be disposed beneath the LED's so that the connectors are not visible when the LED modules are coupled together. The connectors may be disposed along opposite ends of the modules to allow for end-to-end configurations of the modules and/or along side ends of the modules to allow for angled or curved configurations of the modules. The LED modules can be powered via one or more wires, magnets, or clips, which are coupled to a power source.

  • Patent number: 8733967
    Abstract: A portable terminal includes a housing, a light tube arranged along at least one part of a circumference of the housing, and a tube guide mounted along the circumference of the housing. As light is incident on the light tube and propagates along the light tube, the light radiates through a circumferential surface of the light tube, and the radiated light is diffused through the tube guide.

  • Patent number: 8721113
    Abstract: A cover and a lamp structure. The cover whose curvature has a light incident surface and a light outgoing surface, and includes a plurality of 3D micro-structures disposed thereon and arranged in the form of an array. When a light is emitted into the light outgoing surface from the light incident surface, the light emitting angle of the light outgoing surface is increased through the refraction of the 3D micro-structures, so that the occurrence of mura or spots due to uneven distribution of the light is avoid.

    Abstract: This disclosure relates to lighting fixtures, such as suspended lighting fixtures. Devices according to the present disclosure provide lighting fixtures capable of emitting in one or more primary directions, while simultaneously emitting in a direction toward a mount surface, reducing undesirable areas of insufficient light and more efficiently illuminating a space. Lighting fixtures disclosed herein can achieve this increase in illumination efficiency in many ways, including utilizing various lighting element arrangements, such as dual-sided lighting elements, and various lens arrangements, such as lens shape affecting the direction of emitted light.

  • Patent number: 8708518
    Abstract: A luminaire includes a single luminaire housing that includes thermally isolated light source and power control device compartments. At least one light source is disposed within the luminaire housing, and at least one power control device is disposed within a second, thermally isolated compartment. The light source and power control device compartments are separated by a chamber that includes a substantially nonconductive member, which prevents heat from the light source compartment from travelling to the power control device compartment. Thermally isolating the power control device from at least a portion of the heat generated by the light source allows the power control device to be disposed relatively close to the light source without becoming overheated and damaged. A hollow, threaded rod extends between and couples together the light source compartment and power control device compartment.

  • Patent number: 8692449
    Abstract: LEDs are considered to be point light sources. Visible light provided by one or more light emitting diodes (LEDs) is passed through a light diffuser. The LEDs and diffuser are mounted inside a transparent or light-transmissive non-evacuated envelope and bulb. The light emitted from the bulb appears to originate from a filament used in conventional light bulbs rather than from a point light source.

  • Publication number: 20140078728
    Abstract: Embodiments of the present invention provide light fixtures having lenses and light engine units for use therein. To mimic the size and appearance of fluorescent bulbs in existing fixtures, LEDs are may be arranged on light bars or mount surfaces with integrated lenses to diffuse the light and shape the output beam. One or more LEDs can be mounted along the length of a base of the light engine which can then be inserted into a fixture. An elongated lens is mounted to the base over the LEDs so that light emitted from the LEDs interacts with the lens before it escapes the fixture. These lenses may be extruded from a diffusive material and can be shaped in various ways. For example, the lenses may be shaped to disperse more light to the sides, i.e., in a direction away from a normal axis that is perpendicular to the base.
