摘要： 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.

摘要： An enclosure is divided into first and second portions by a theoretical plane defined by a horizontal line. LEDs are mounted on an LED board in the enclosure and are operable to emit light when energized through an electrical path. A first pin is mounted to a first end of the enclosure and a second pin mounted to a second end of the enclosure, both pins being in the electrical path. Braces support the LED board and comprise first and second legs. The first leg and second leg extend to a first point and a second point of intersection of the plane and the internal surface of the enclosure, respectively. A first conductor connects the first pin to the LED board and a second conductor connects the second pin to the LED board. The first conductor and first pin and the second conductor and the second pin are one-piece.

摘要： 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.

摘要： A solid-state lamp with an angular distribution optic is disclosed. Embodiments of the present invention can provide for improved luminous intensity distribution in the vertical plane for a vertically oriented solid-state lamp. A lamp according to some example embodiments of the invention includes at least one LED, an optically transmissive enclosure for the LED or LEDs, and a base. The lamp also includes a distribution optic conformably disposed in or on the base to conduct light for angularly distributed emission from the base of the lamp.

摘要： A LED lamp has a non-optically transmissive base connected to an optically transmissive enclosure. A LED assembly emits light when energized through an electrical path from the base. A portion of the heat sink and lamp electronics extend from the base and into the enclosure such that at least an upper portion of the heat sink extends into the interior volume defined by the enclosure. The LED assembly is supported on top of the heat sink such that the LEDs are disposed in the volume of the enclosure. An optic element extends over the LEDs and at least the portion of the heat sink. The size of the non-optically transmissive base of the lamp is reduced relative to the optically transmissive enclosure such that a greater ratio of optically transmissive view space to non-optically transmissive base is provided.
