Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

Abstract: A solid state light having a solid state light source such as LEDs, a light guide having an enclosed interior volume such as a bulb shape without vents, and a thermal guide. The light guide is coupled to the light source for receiving and distributing light from the light source. The thermal guide is at least partially contained within the interior volume with an air gap between a portion of the thermal guide and the light guide. The thermal guide provides for thermal conduction from the light source and dissipating heat through convection and radiation for cooling the light.

Abstract: A light having integrated light and thermal guides and separable electrical connectors. The light has a base for connection to a power supply, a light circuit electrically connected with solid state light sources such as LEDs, and a driver circuit for receiving power from the power supply and providing power to drive the light sources. A light guide is coupled to the light sources for receiving and distributing light from the light sources, and a thermal guide is integrated with the light guide for providing thermal conduction from the light source for cooling the light. The separable connectors include a first connector for providing an electrical connection between the driver circuit and light circuit, a second connector for providing an electrical connection between the power supply and driver circuit, and a third connector for providing a ground connection to the driver circuit.

Abstract: A light with integrated light and thermal guides, and having solid state light sources such as LEDs. The light guide includes a material having a first surface and a second surface opposite the first surface and forming an interior volume. The light guide is coupled to the LEDs for receiving and distributing light from them through the first surface, and the light is transported through the light guide until the light is extracted from the first or second surface. The light guide can include alignment features such as fiducials that mate with a base. The thermal guide is contained within the interior volume and integrated with the light guide for providing thermal conduction from the LEDs for cooling the light. The thermal guide can be vented to provide for internal cross flow of air for the cooling.
