Abstract
A lighting system includes a light emitting element operable to emit light at a level between zero and 100 percent, a light level sensor positioned to detect a total level of light, and a motion detector positioned to detect a motion in a predefined space. A controller is coupled to the light emitting element, the light level sensor, and the motion detector and is operable to compare a measured total level of light to a set point and to activate the light emitting element in response to the measured total light level being below the setpoint. The controller is further operable to activate the light emitting element in response to the detection of motion within the space.
Claims20
A lighting system comprising:
- a light emitting element operable to emit light at a level between zero and 100 percent,
- a light level sensor positioned to detect a total level of light;
- a motion detector positioned to detect a motion in a predefined space;
- a controller coupled to the light emitting element, the light level sensor, and the motion detector and operable to compare a measured total level of light to a set point and to activate the light emitting element in response to the measured total light level being below the setpoint, the controller further operable to activate the light emitting element in response to the detection of motion within the space.
A lighting system comprising:
- a plurality of fluorescent light emitting units arranged to emit light in an area between a level of zero and 100 percent;
- a light level sensor positioned to detect a total level of light and transmit a signal indicative of a measured light level;
- a controller operable to receive the measured light level and compare the measured light level to a pre-set desired light level and to adjust the plurality of fluorescent light emitting units in response to that comparison to emit a level of light between zero and 100 percent in order to change the measured light level to substantially match the preset desired light level;
- and
- a remote control device operable from a position apart from the controller to change the preset desired light level.
A method of controlling a light level within a space, the method comprising:
- sensing a current light level at a predetermined location;
- storing a first desired light level in a controller;
- comparing the sensed light level with the first desired light level;
- adjusting the light output of a plurality of fluorescent lights in response to the comparison of the sensed light level to the first desired light level until the sensed light level is about equal to the first desired light level;
- remotely adjusting the desired light level to a second desired light level;
- and
- adjusting the light output of the plurality of fluorescent lights in response to a comparison of the sensed light level to the second desired light level until the sensed light level is about equal to the second desired light level.
