Abstract:
A light emitting apparatus comprises: an LED-based light source; a spherical, spheroidal, or toroidal diffuser generating a Lambertian light intensity distribution output at any point on the diffuser surface responsive to illumination inside the diffuser; and a base including a base connector. The LED based light source, the diffuser, and the base are secured together as a unitary LED lamp installable in a lighting socket by connecting the base connector with the lighting socket. The diffuser is shaped and arranged respective to the LED based light source in the unitary LED lamp to conform with an isolux surface of the LED based light source. The base is operatively connected with the LED based light source in the unitary LED lamp to electrically power the LED based light source using electrical power received at the base connector.

Abstract:
An illuminating device includes a light source including a lighting device, such as a solid state lighting device, which emits light, a phosphor material which converts at least a portion of the light emitted by the lighting device to light of a different wavelength. A controller adjusts a ratio of on time to off time of a current waveform supplied to the lighting device. This enables the color of light emitted by the light source to be controlled.
Abstract:
An article of manufacture comprises a thin film solid state lighting device, such as an organic light emitting diode (OLED) device, having a planar light emitting side and an opposite planar mounting side and including electrodes disposed on the planar mounting side of the thin film solid state lighting device, the electrodes including a magnetic material configured to conductively convey electrical drive current to drive the thin film solid state lighting device to emit light at the planar light emitting principal side. The article of manufacture may further comprise a fixture having a planar surface with magnets arranged to mate with the electrodes to magnetically secure the thin film solid state lighting device with the fixture and to concurrently form electrically conductive paths including the magnetic material of the electrodes configured to conductively convey electrical drive current. Thus this magnetic connection provides both mechanical support and electrical conduction path.
