A LED dimming circuit is provided. The LED dimming circuit has an LED driver, an LED dimmer, and at least one LED light source. A resistor is connected between a dimming control output of the LED dimmer and dimming control input of the LED dimmer. The LED dimming circuit may optionally include a fluorescent slide dimmer. The fluorescent slide dimmer may have a first connection to the dimming control input of the LED dimmer and a second connection to a circuit common of the LED dimmer. A method of providing an LED dimming circuit for dimming at least one LED light source using a fluorescent dimmer is also provided.

An emergency lighting system comprises a wall unit housing that may readily be located and secured between wall studs in a conventional structure. The housing includes a rotatable door to which an emergency lamp is secured, said door being in a closed position when main electrical power is on such that the lamp is hidden within the housing. The rotatable door is coupled to a motor that is supplied battery power when main electrical power loss is detected, thereby rotating the door to an open position and exposing the emergency lamps. The emergency lamps are also illuminated by battery power.

The instant invention is a luminaire comprised generally of mounting plate including a plurality of mounting blocks secured to said mounting plate; and a plurality of LEDs, wherein at least one of said LEDs is positioned upon each of said mounting blocks. The mounting blocks include face portions having a plurality of pitches or angles and may be arranged in a plurality of configurations on said mounting plate.

An improved efficiency fluorescent lighting system is described. The system utilizes reduced rows of fluorescent luminaires which are spaced much further apart than traditional spacing. The luminaires used in the system of the present invention have increased light output of each luminaire by up to fifty percent through a combination of use of a high efficiency lamp producing about 3250 lumens, an electronic dimming ballast having a ballast factor of about 1.2 and a luminaire having a spacing to mounting height ratio of at least 1.5.

Efficient fluorescent lighting system

In order to spread the light being emitted from an LED, an LED light spreader has a light conductive end, an optical path conversion side, and a light transmitting side. The present invention enables a single LED to simulate the effect of having several discrete LEDs on a circuit board or may be configured to give the effect of having a single elongated light source.

An interactive system on a server via which a client can remotely submit data used to making photometric calculations in which the system has one or more interrogative interfaces is provided. Data is requested from the client via the interrogative interfaces when the client accesses the system. Data is received from the client by the interactive system. Photometric calculations are performed using the data received from the client and the results of the photometric calculations are delivered to the client.
