Patent number: 11274018Abstract: Elevator interior lighting provided by a temporary LED light fixture and power supply installed on or adjacent an elevator canopy. The temporary LED power supply comprises an LED driver and an emergency LED power supply. The LED driver connects to LEDs of the temporary LED light fixture and supplies sufficient power to provide code-compliant temporary lighting in the cab. The emergency LED power supply module connects to one or more emergency LEDs and supplies sufficient power to provide code-compliant emergency lighting in the cab upon loss of primary electrical power. To minimize costs when converting to permanent lighting, additional LED light fixtures can be added and connected to the same temporary LED power supply, and the emergency LED power module may be relocated into a down light power supply to power two or more down lights in the event of a loss of primary electrical power.Type: GrantFiled: August 5, 2020Date of Patent: March 15, 2022Assignee: MAN-D-TEC INC.Inventors: Terry Roy Mandy, Dalton John Mandy
