|20150085499||Light Fixture Mounting Assembly - A light fixture mounting assembly that includes a lamp housing having a sidewall and an opening defined by a rim at one end of the sidewall and a detent extending outward from the sidewall in a position to engage an outer surface of a panel when the housing is in an installed position. A lamp module is carried within the lamp housing and comprises a lamp positioned to emit light through the housing opening. The lamp housing is configured to carry either a spring clip-type retainer or a hose clamp-type retainer to hold the lamp housing in the installed position.||03-26-2015|
|20150044957||Elevator Ventilation Fan Assembly - An elevator ventilation fan assembly for hazardous operating environments and comprising a fan disposed within an enclosure to be carried on an elevator cab roof. The fan may be suspended by a fan support framework from at least three non-co-linear suspension locations of the enclosure lid. The assembly may include a vibration isolation element disposed between the fan motor and the enclosure lid, a cover panel supported by a cover support framework on the enclosure lid, a fan guard screen carried by the enclosure lid, a fan motor junction box carried within the enclosure by the lid and accessible via a removable side panel of the enclosure, and/or a fan duct surrounding the fan.||02-12-2015|
|20140252948||Elevator interior illumination - An elevator interior illumination assembly comprising a primary LED driver that provides conditioned DC power to primary and backup LEDs when AC power is available from a primary electric power source. The backup LEDs receive DC power from a backup electric power source when AC power is not available to the primary LED driver from the primary electric power source.||09-11-2014|
|20120187852||Elevator Emergency LED Lighting Power Supply Assembly - An elevator emergency LED lighting power supply assembly including an inverter that receives DC power from a battery and outputs backup power to LED lamps of an elevator lighting system. An LED driver is connected to the inverter, is connectable to an LED lamp of the elevator lighting system, receives AC power from the inverter, and outputs DC power sufficient to power an LED lamp. A relay is connected between the inverter and the LED driver, is connectable to a primary elevator electrical power supply, and allows AC power to flow from a primary elevator electrical power supply to elevator lighting system LEDs through the LED driver as long as AC power is available from a primary elevator electrical power supply. Upon loss of power from the primary elevator power supply the relay switches contacts and provides to the LED driver AC power received from the inverter.||07-26-2012|
|20120106138||Illumination Assembly - An interior illumination assembly comprising a lamp housing mountable on an interior panel and a lamp removably supportable within the lamp housing. The lamp includes an LED module carrying an LED and removably receivable by the lamp housing into an installed position in the lamp housing. A lens is disposed across the module opening and a reflector carried by the LED module reflects light from the LED through the lens into the compartment.||05-03-2012|
