  • Patent number: 8721119
    Abstract: A light emitting diode (LED) display screen including a plurality of LED display modules is disclosed. Each of the plurality of LED display modules includes a flexible substrate having a first surface and a second surface, opposite to the first surface, on which a plurality of LEDs are disposed; a power cable having a socket or a plug, the power cable being disposed on the first surface; a data cable having a socket or a plug, the data cable being disposed on the first surface; a magnet disposed on the first surface; and a plurality of connectors fixed to the flexible substrate, the plurality of connectors being disposed on the first surface and including a male connector and a female connector. A height of the magnet from the first surface of the flexible substrate is higher than heights of any components disposed on the first surface.

  • Patent number: 8678611
    Abstract: A light emitting diode (LED) lamp includes a tube having a transparent first section and an opaque second section. An LED disposed inside of the tube. The second section is has an inner surface having a light diffusive surface so that the LED light is diffusively reflected. The LED is disposed so that a total amount of direct light from the LED to the first section is smaller than a total amount of indirect light that is incident on the first section as a result of being reflected by the second section (i.e., scattered or diffused light). The LED is disposed so that a light axis of the LED points toward the inner surface of the second section.

  • Patent number: 8562172
    Abstract: An end cap for a light-emitting-diode (LED) light tube includes an end cap housing having an end surface, an electric circuit and a switch for closing the electric circuit or opening the electric circuit. The switch includes a switch body having a pivot axis. The switch body is configured to pivotally move, with respect to the pivot axis, between an on-position for closing the electric circuit and an off-position for opening the electric circuit. When the switch is in the off-position, an end part of the switch body protrudes from the end surface of the end cap housing, and when the switch is in the on-position, the switch body and is substantially flush with respect to the end surface. When the switch is in the off-position, an outer surface of the switch body inclines with respect to the end surface of the end cap housing.

  • Patent number: 7963674
    Abstract: A light emitting diode package comprising a substrate electrically connectable to an external unit with a reduced height. A flexible PCB for electrical connection between a light emitting diode and the external unit is directly connected to a light emitting element. The direct connection is conducted by applying a conductive resin to an electrode on the flexible PCB, on which the light emitting element is mounted; mounting the light emitting element; curing the conductive resin in a high-temperature furnace. The present invention requires neither a lead frame for electrical connection of the light emitting element to the flexible PCB nor a rigid PCB for supporting the flexible PCB, thus reducing the total height of the light emitting diode package.
