    Abstract: A retrofit-style lamp is disclosed. The retrofit-style lamp includes a plurality of light sources, and a one-dimensional linear batwing lens. The one-dimensional linear batwing lens beam shapes light emitted by at least two light sources of the plurality of light sources. The retrofit-style lamp also includes a housing including the plurality of light sources, and attached to the one-dimensional linear batwing lens. The combination of housing and lens is then itself fitted with endcaps, including electrical connectors, for placement within a fixture, such as within an existing conventional fluorescent tube fixture located within a storage structure, for example a refrigeration case. Alternatively, the plurality of light sources, the one-dimensional linear batwing lens, and the housing may be formed, along with a power supply, as a standalone retrofit fixture for use in enclosed storage structures, such as refrigeration cases, where the retrofit fixture replaces a conventional fluorescent fixture.

  • Patent number: 9291312
    Abstract: An LED tube has a tube body, an LED light board and two caps. The tube body has a translucent tube shell and a heat dissipating seat. The translucent tube shell has two openings and a gap. The heat dissipating seat is mounted in the gap. The LED light board is mounted in the tube body and has a luminous surface, wherein two opposite ends of the LED light board extend out of the heat dissipating seat. The luminous surface has four electrical connecting parts, wherein each two electrical connecting parts are respectively mounted near a corresponding one of the two opposite ends, thus, the four electrical connecting parts are mounted away from the heat dissipating seat to extend internal creepage distances between the four electrical connecting parts and the heat dissipating seat, and further increase electrical safety of the LED tube.

  • Patent number: 9280180
    Abstract: An information handling system provides connectors along a housing periphery with a reduced vertical footprint by adjusting a display circuit portion relative to a display panel portion to provide vertical space for the connectors. For example, the circuit portion aligns with the display panel portion along one side of the display to provide space for connectors at that side of the display, and the circuit portion extends past the perimeter of the display panel portion at an opposing side of the display. In one embodiment, the circuit portion extending outside the perimeter of the display panel portion includes circuits for powering a backlight disposed in the circuit portion.

  • Patent number: 9127821
    Abstract: A luminaire includes a fixture, a light engine, and a heat flange. The fixture is configured to be received in a recess of a support surface and defines a cavity having a radius R. The light engine is disposed within the cavity and includes at least one light source. The heat flange is disposed about a distal end region of the fixture and includes a hollow, generally conical frustum shape extending radially outwardly from the fixture and extending away from the distal end region of the fixture. A distal-most end of the heat flange is configured to be disposed a distance D from the support surface when the fixture is received in the recess, the distance D being greater than or equal to 0.4R. Thermal energy is conductively transferred from the light engine, through the fixture, to the heat flange where the thermal energy is convectively transferred from the heat flange to surrounding air to create air currents flowing along the support surface thereby reducing the junction temperature.

  • Patent number: 9127828
    Abstract: A lamp with uniform illumination pattern is used for continually illuminating an illuminated area and includes at least one light module. The at least one light module includes two light sources respectively having different light intensity and arranged orderly. Two extension lines of two optical axes of the two light sources have one crossover point. Light emitted from the light source with less light intensity illuminates the illuminated area which is closer to the light module, while light emitted from the light source with greater light intensity illuminates the illuminated area which is farther to the light module. Light emitted from the light source, which is father to the illuminated are, can make up the intensity losses of attenuation since light emitted from the light source which is father to the illuminated area have greater light intensity. As a result, the lamp has uniform illumination pattern.

  • Patent number: 8979299
    Abstract: A linear light-emitting diode (LED) tube lamp having a readily retrofittable modular structure enables consumers or manufacturers to readily retrofit the lamp by replacing an LED module or internal electronic control units that include an LED driver in maintenance or lamp upgrade without hazards. The readily retrofittable modular structure includes a core assembly in each of lamp bases for easily securing or removing the electronic control unit through a mechanical securing means, and two sets of connection modules for quickly connecting and disconnecting the electronic control unit with the LED module. The readily retrofittable modular structure may use one bi-pin or two bi-pins to connect to the AC mains via pluggable wire for delivering power to the LEDs. Thus, the LLT lamp using the readily retrofittable modular structure may be configured as single-ended, double-ended, or double-ended with double shock-protection switches and can be cost-effectively retrofitted after initial installation.

  • Patent number: 8960958
    Abstract: A light-emitting diode (LED) troffer adopts LED light sources mounted along two lengthwise sides of an LED module that uses a reflecting diffuser and a diffused light exit window to sufficiently average white light emissions from a plurality of LEDs or to properly mix light emissions from white LEDs at correlated color temperature (CCT) of 6,200±300 K with emissions from LEDs having saturated colors for uniform and tunable CCT light outputs having a consistent intensity or color hue within viewing angles. The troffer adopting a retrofittable design enables single person to readily hang and secure the LED module single-ended on top of the troffer for installation, retrofit, and inspection. The troffer uses such an integrated LED module with a power density less than 0.0127 W/cm2, and thus no apparent heat sink is needed.
