Emergency and exit light

System and method are provided for controlling emergency lighting where emergency lights turn on when main source of power goes out for controlling emergency lighting to conserve energy utilized by the emergency light, while maintaining good visibility of the emergency lighting. Solid state lighting, such as LED, is used within an emergency light to add light in blue wavelength region matching the light output to the most sensitive of wavelength response of the human eve to increase color perception and allows faster response time. Electrical current to the device and light output are reduced while LED light tends to increase its blue wavelength component as it is dimmed thus increasing effective light output. After a predetermined time, the light is purposefully dimmed to conserve energy and to allow the eye to slowly and safely adjust to the new lighting conditions. By reducing electrical current, energy storage batteries may be smaller than for similar unit that maintains constant light output.

Scotopically enhanced emergency light and control thereof

Outdoor emergency lighting fixture

A lighting fixture that is adjustable to allow the emitted light to be aimed and focused to suit the application. The adjustable lighting fixture has a housing having an inner surface. First and second mounting arms extend from the inner surface. A reflector has upper and lower surfaces. First and second mounting members extend from the upper surface and are connected to the first and second mounting arms. A first aperture in the reflector receives a first lamp. The first lamp is movable along a first longitudinal axis through the first aperture to focus the emitted light.

Emergency lighting fixture having adjustable reflector and lamp assembly

A reflector for a lighting fixture that provides a uniform level of lighting. The reflector has a first arcuate portion having a first upper surface and a second arcuate portion having a second upper surface. A first aperture in the first arcuate portion is adapted to receive a first lamp. A second aperture in the second arcuate portion is adapted to receive a second lamp. First and second mounting members on the first and second upper surfaces are adapted to be connected to a lighting fixture housing.
