    Abstract: A lamp comprises an enclosure that is at least partially optically transmissive. The enclosure comprises an optically transmissive lens and a base where the lens is connected to the base; and a LED board supporting an LED. A first of pins and a second pair of pins are rotatable relative to the enclosure and are in the electrical path supplying power to the LEDs. The lamp is positioned between a pair of tombstone connectors such that the first pair of pins engages the first tombstone connector and the second pair of pins engages the second tombstone connector. The first and second pair of pins are inserted into the tombstone connectors and are rotated to engage the electrical connectors in the tombstone connectors.

    Abstract: In a first embodiment, a lighting fixture is configured as a power over Ethernet (PoE) powered device (PD), which is capable of facilitating Ethernet-based communications with and receiving power from a PoE device, such as a PoE switch, over a single cable. In a second embodiment, a lighting fixture is configured as a PoE power source equipment (PSE) device, which is capable of facilitating Ethernet-based communications with and supplying power to one or more control elements.

    Abstract: Driver circuitry is coupled between a power supply and at least one LED in a solid-state lighting fixture, such that a non-isolated direct current (DC) path exists between the power supply and the at least one LED. The driver circuitry is configured to receive an AC input voltage and generate a driver output current for driving the at least one LED from the AC input voltage. By using driver circuitry that is non-isolated from the at least one LED in the solid-state lighting fixture, the efficiency of the driver circuitry may be increased, while simultaneously reducing the cost and complexity of the driver circuitry compared to conventional driver circuitry.

    Abstract: A lighting fixture includes a solid-state light source and driver circuitry. The solid-state light source includes at least one light emitting diode (LED). The driver circuitry includes one or more silicon carbide (SiC) switching components, and is coupled to the solid-state light source. Further, the driver circuitry is configured to receive an alternating current (AC) input voltage and generate a driver output current for driving the at least one LED from the AC input voltage. By using silicon carbide (SiC) for the switching components in the driver circuitry, the efficiency of the driver circuitry and thus the lighting fixture may be significantly increased, while simultaneously reducing the cost and complexity of the driver circuitry and thus the lighting fixture when compared to conventional lighting fixtures.
