Abstract: A lighting device includes a housing, a light emitting device, and an optical array. The housing has a base and the light emitting device is connected to the base for producing a light output. The optical array includes a lens and removably connects to the base. The optical array is repositionable on the base to modify the light output.

Abstract: A luminaire includes a housing, a plurality of fins, and an LED module. The housing includes a first compartment having a top wall, a side wall extending from the top wall, and a first opening in the side wall. The plurality of fins is positioned in the first compartment so that at least one fin is in communication with the first opening. The LED module is connected to at least one of the heat fins and includes a PCB, a bezel, and at least one LED.

Abstract: An example laparoscopic trocar assembly can be used for insertion of a ventriculoperitoneal (“VP”) shunt into an abdomen and comprises an optical system a trocar sleeve to allow a surgeon to see abdominal tissue being punctured and see into an abdominal cavity. An example trocar assembly comprises an entry port in the trocar's side and a stylet to insert a VP shunt tube into an abdomen. An example trocar assembly comprises a transparent dissecting obturator with a sharp edge to puncture an abdominal wall and an optical system or camera to allow a surgeon to see inside of an abdominal cavity to avoid injury to blood vessels and internal organs during surgery. An example trocar comprises a side channel through which a VP shunt tube can be inserted into an abdominal cavity at the same point of insertion as the trocar.

Abstract: An optical assembly including a mounting board and an LED coupled to the mounting board. An optic component, for example a lens, is coupled to the mounting board and encloses the LED. A shield member including 5 VA rated material is positioned to have a first surface in contact with the mounting board and a second surface in contact with the optic component.

Abstract: The present invention relates to an emergency lighting system comprising one or more first lighting elements and a power supply/charging unit that is incorporated in a host lighting fixture having one or more second lighting elements such as an HID, incandescent or fluorescent lamp. Optionally, a heating element can be provided that allows operation of the system in temperatures too low for operation of conventional emergency lighting systems.
