A lighting control system is an intelligent network-based control solution for lighting that involves communication between various system inputs and outputs related to lighting control, using one or more central computing devices. In a smart home systems, lighting controllers enable a lighting system to check the occupancy and natural light in an area. The system can determine these aspects and adjust its luminosity according to the amount of natural light present, or switches off automatically if the area is unoccupied.
Lighting controls are essential components of energy-efficient lighting systems, which combine sources of electric light with daylight to create a pleasant ambiance while saving energy and costs. Thus, it helps meet the demand for energy-saving and environmental sustainability.
Lighting controllers can be as simple as an on/off switch or can be a sophisticated, logic-based, microprocessor-controlled system. Lighting control decisions are based on a large number of factors such as the time of day, occupancy, light level, temperature, and individual requirements. Lighting control provides flexibility with respect to the lighting operation, which improves ambiance, interior decoration, and productivity.
Most of the lighting systems use LED systems that are controlled by a combination of conventional line-voltage load controls using typical wall stations and daylight sensors to reduce the use of electric lighting when it is not needed, thereby cutting down electricity bills and the overall household expenditure. Lighting systems are capable of reacting to the actual conditions in a space, such as the occupancy of the space or amount of natural light in a room, thereby providing only the required amount of artificial light.
Relays control lighting power supply by mechanically opening or closing it according to the signals sent from low-voltage rocker switches, time clocks, or computer-based energy management systems. Passive lighting control of relay systems is mainly used in large facilities with big rooms that do not require dimming. The passive lighting control system consists of an occupancy sensor, an electronic controller, and a controllable relay. A relay works as an on/off switch in this system. The occupancy sensors detect the physical presence of individuals to determine if there are occupants in the space. Based on this, a signal is sent to the controller; the controller then uses this signal to activate the relay to switch the lights on or off.
General Electric Company (US), Honeywell International Inc. (US), Schneider Electric SE (France), Lutron Electronics Co., Inc. (US), and Leviton Manufacturing Co., Inc. (US) are a few of the major relay providers for lighting control applications.
Occupancy sensors in Smart Home Systems use infrared (IR) or acoustic technology, or a combination of the two. These sensors are used to minimize energy consumption and improve usability and control. After detecting the presence of people in facilities, these sensors can switch lights on and off accordingly. These are widely used in places that are often unoccupied such as restrooms, storage rooms in homes corridors, stairwells, and parking areas.
A control system installed with occupancy sensors can detect the presence or absence of people in a particular space and accordingly send a signal to the relay to open or close the circuit. Though a lamp’s shelf life may be somewhat shortened by the increased rate of switching due to occupancy sensors, the overall shelf life of lamps is usually extended by the reduced daily burn hours. Originally designed for use with security systems, occupancy sensors have been refined and enhanced to control lighting and HVAC in residential spaces as well.
