  • 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.
