automatic light control system

the control system receives information, decides what to do with it, and then adjusts lighting power accordingly. the input may be manual, automatic or a combination of the two, as shown in this drawing depicting the functionality of a manual-on wallbox occupancy sensor. control zoning is an important aspect of lighting control system design, as zoning is the mechanism through which lighting controls are assigned to lighting loads. the sequence of operation is a description of system outputs in response to various inputs for each control point. a pair of wires forms a bus, or transmission path for control signals connecting multiple luminaires and control devices that communicate. they communicate control signals from a wireless transmitter to a wireless receiver in a lighting controller, which is installed at the luminaire, a junction box or at a panel.

scheduling adjusts the output of the lighting system based on a time event implemented using a time-clock, which may be implemented using a microprocessor built into the control system. daylight-responsive control (also called daylight harvesting) uses a light sensor (also called a photosensor or photocell) with a power controller to switch or dim lighting in response to available daylight. data feeds to a server or the cloud for retrieval and use via software. some systems enable the controllers to connect with each other and to a central server for scalable centralized networked lighting control. this allows luminaires to be zoned and rezoned individually or in groups and with multiple control strategies. operating software and data reside on a central server or in the cloud. it would be nice to have a variety of dim controls from 0-10v, dmx, direct led dim, and dali.

no matter what type you use, the most important thing to remember for any lighting control is to use a type of lightbulb that doesn’t need to “warm up.” occupancy sensors that activate when people are near them are helpful indoors, as long as they’re positioned to detect people in any corner of the room. they’re also good as task lighting — above places like a desk or kitchen sink — so you get the extra light you need while working, but you don’t forget and leave it on all night. ultrasonic sensors detect sound; infrared sensors detect heat and motion. plug timers into a wall outlet or install them in the wall, like a light switch or thermostat.

photosensors are generally best outdoors, but new applications have found they’re also useful for led nightlights. central lighting controls are another efficient way to reduce lighting costs. the potential energy savings from installing even a simple central lighting control system are more than most people realize. if a lighting control system allows you to conveniently switch lights on only when needed, your total lighting use reduces greatly. if you already have or are thinking about installing an outdoor security light, consider combining it with a photosensor to keep it from burning all day. timers are commonly used for aesthetic or holiday lighting, sometimes in conjunction with a photosensor — so they turn on at dusk and turn off at a designated time.

with automatic control, a signal from a sensor (occupancy or light sensor), computer or another building system provides the input. reduce your lighting costs with lightstat automatic lighting controls (alc). our sensor based controls prevent energy waste by conforming to your company’s lighting control systems will make your home more efficient as there is a centralized control of each aspect of lighting. through the smart, types of lighting control systems, types of lighting control systems, lighting control system pdf, lighting control system brands, best lighting control system.

the controls range from simple twist knob controls to micro-processor based lighting sched- uling systems. timers can be very effective for applications where having an automatic home light control system will let you turn the lights on and off with just a tap of a button. you can also choose to turn on all the lights z-wave technology makes a simple lighting control system that switches lights on and off and dims them. whether you can’t train your kids to turn out lights, smart lighting control systems, commercial lighting control systems, networked lighting control systems, lighting control system basics.
