Abstract: An LED lamp includes an elongated at least partially optically transmissive enclosure. The LEDs are mounted on an LED board. The enclosure has a support structure for supporting the LED board. The support structure is formed as one-piece with the enclosure and of an optical material. A pair of end caps are secured to the ends of the enclosure using a snap-fit connection. The end caps retain pins for connecting to a light fixture.

Abstract: A LED lamp includes an at least partially optically transmissive enclosure and a base. A LED assembly comprising at least one LED is located in the enclosure and is operable to emit light when energized through an electrical path from the base. A heat sink comprises a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the at least one LED. The heat sink is connected to the base by a snap fit connector comprising a deformable first member on one of the base or heat sink engaging a second member on the other one of the heat sink and the base. A retention member holds the first member in engagement with the second member. A seal is positioned between the heat sink and the base, the seal being compressed between the heat sink and the base.

Abstract: A lighting apparatus a first group of at least one first solid state emitter, each first solid state emitter including a first light emitting diode (“LED”) that, when excited, emits light having a peak wavelength in a range between about 440 nm and about 475 nm, and a second group of at least one second solid state emitter, each second solid state emitter comprising a second LED that, when excited, emits light having a peak wavelength in a range between about 390 nm and about 415 nm. Between about 2% and about 15% of a spectral power of light emitted from the lighting apparatus is light having wavelengths in the range between about 390 nm and about 415 nm.

Abstract: A PWM dimmer includes a source terminal, a load terminal, a power stage, an interface, and control circuitry. The power stage is coupled between the source terminal and the load terminal and is configured to receive from the source terminal an AC supply signal and provide a pulsed AC load signal to the load terminal in response to a control signal. The AC supply signal has a sinusoidal envelope with a positive half-cycle and a negative half-cycle for each cycle. The pulsed AC load signal tracks the envelope and includes a plurality of pulses in the positive half-cycle and the negative half-cycle for each cycle. The interface is configured to receive dimming control information bearing on a dimming level from a user or remote terminal. The control circuitry is configured to receive the dimming control information from the interface and generate the control signal based on the dimming control information.

Abstract: A LED lamp has at least two LEDs to provide light of at least two different spectral outputs. An optic element has an entry surface disposed to receive the light from the LEDs. The entry surface includes refracting surfaces that refract the light tangentially. The refracting surfaces may extend radially relative to a center of the entry surface. The refracting surfaces may be continuously curved in cross-section where the refracting surfaces may include convex refracting surfaces and concave refracting surfaces.

Abstract: A lighting controller comprises power circuitry, transmitter circuitry, a touch-sensitive panel, and processing circuitry. The power circuitry is configured to relay power from the lighting controller to a solid state lighting fixture wired to the lighting controller. The transmitter circuitry is configured to wirelessly exchange signals with the solid state lighting fixture. The touch-sensitive panel is configured to emit light and receive touch input from a user. The processing circuitry is electrically coupled to the power circuitry, the transmitter circuitry, and the touch-sensitive panel. The processing circuitry is configured to wirelessly control, via the transmitter circuitry, the attribute of light emitted by the solid state lighting fixture in accordance with the touch input received via the touch-sensitive panel and control the light emitted from the touch-sensitive panel to indicate the attribute as the attribute is wirelessly controlled.
