A structural light fixture for the ceiling of clean room, such as a clean room for pharmaceutical or electronic research or production, includes an outer U-shaped beam and an inner U-shaped beam. The inner U-shaped beam nests within the outer U-shaped beam. The inner and outer U-shaped beams are mutually reinforcing so that the combination of the two U-shaped beams is stronger and stiffer than either U-shaped beam alone. The top side of the outer U-shaped beam is exposed to the outside of the clean room and includes no perforations so that the outer U-shaped beam is a barrier to gas, particulates, microorganisms or disinfectants that otherwise would pass through the clean room ceiling. The removable inner U-shaped beam includes a lamp and power supply, allowing maintenance of the structural light fixture from the interior of the clean room without interrupting the barrier to contamination created by the structural light fixture.

A solar flame lamp for lawn is provided and includes a lamp body including a lampshade and a lamp pole. A lighting assembly is disposed in the lampshade, the lighting assembly is disposed with a circuit board provided with a control circuit, a power supply and a LED assembly. A lower part of the lampshade is disposed with a lampshade handle connected to the lamp pole through the lampshade handle. The control circuit includes an overcurrent and overvoltage protection circuit, a MCU based controller, a switch control circuit and a driving circuit. The power supply is used to provide power to the MCU based controller through the overcurrent and overvoltage protection circuit, the MCU based controller is used to control the driving circuit through the switch control circuit, and the driving circuit is used to drive the LED assembly to light. It can be automatically controlled, multi-functional and low cost.

The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.

A linear light fixture for use in a hazardous environment, the linear light fixture includes a housing body that defines a component compartment therein that is configured to receive electrical components. The linear light fixture also includes a light engine connected to the housing body and including a light emitting diode. The light engine is pivotable with respect to the housing body between a first position, wherein the light engine encloses the component compartment, and a second position, wherein access is provided to the component compartment. The light engine is separable from the housing body.
