Abstract: The present invention is directed to an indirect luminaire, and to a lighting system using at least two such luminaires. The invention comprises a luminaire in which a linear light source and longitudinally linear reflectors are mounted in parallel inside a housing. The reflectors are located underneath and on each side of the light source and have angled facets which are adopted to reflect light to the sides at an upward angle. In the lighting system of this invention, the reflectors beam light onto the ceiling in the midpoint zone between parallel rows of luminaires to provide highly uniform and efficient lighting.

Abstract: An emergency lighting system having a motor drive assembly (34) for the automatic lowering of a battery-powered emergency lamp (12), when normal power to a primary lighting system is lost, from a concealed position behind a ceiling (11), and returning the lamp (12) to its original position when normal power is restored. Included in the assembly (34) are gears including a motor driven gear (36) and a crank arm driving gear (38). The presence of a normal electric current to the primary lighting system powers the motor drive assembly (34) to return and maintain the emergency lighting system in its concealed position. Interruption of normal electric power automatically results in driving of the emergency power system from its concealed position to an extended position for use, as a result of crank driving gear (38) being rotated in a direction opposite that in which it is rotated for return of the emergency system to the normal concealed position.
Abstract: The invention pertains to a stroboscopic timing light for use with internal combustion engines. The reflector assembly is designed to increase the proportion of light from a flash tube that becomes part of a focused light beam. The reflector assembly comprises a pair of angled reflectors or series of reflectors forming a frusto-pyramid-like structure which reflects an array of images of a flash lamp. These images reflect the substantial portion of the light from the flash lamp while providing a cost effective and relatively inexpensive reflector assembly.
Abstract: A turn signal assembly for use on trucks wherein the turn signal is normally in a retracted position flush with the side of the truck and upon activation is transposed to an extended position protruding from the side of the truck such that the turn signal is visible to adjacent vehicles.
Abstract: Two thermal protectors or thermostatic sitches are mounted on the outside of the housing of a combination ventilator/lamp unit to sense any heat build-up in the housing during operation of its lamp. One switch is normally open and is connected between the lamp and the motor for the ventilator fan; and the other switch, which is normally closed, is connected in series with the fan motor and lamp. The normally open switch is set to close automatically when the temperature in the housing reaches a first value above room temperature, thereby to energize the fan motor to cool down the housing. If the normally open switch and/or the fan motor fails the normally closed switch is set to open at a temperature above that at which the normally open switch closes, and functions as a safety switch to disconnect both the fan motor and lamp from the power supply.
