A lighting control systems are an intelligent network-based lighting control solution that incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces.
Lighting plays an important role in our everyday lives, it’s not something the average person thinks about very often. Clearly, we all need light to see, but lighting plays a much more substantial role than you might have first imagined. Not only does it help set the mood and, the ambiance of a room but contributes to our mental well-being and how well we sleep too.
But to get the very best from your lighting, you must consider the reliability, flexibility, and how it’s controlled as a complete system – that’s where lighting controls come in. So, given the increase in demand for lighting control across domestic properties, we thought it was time to highlight some of the benefits implementing such a system can have on your home.
1. Basic Lighting controls
A basic lighting control consists of a manual on/off switch. In order to save money with these types of lighting controls, the individuals in the building must remember to turn them on when they enter the room and turn them off when they leave. Using energy-efficient light bulbs, like LEDs and CFLs, with basic switches can help reduce electric bills.

2. Dimmer Switches
Dimmer switches are a slightly more advanced way to control room lighting. These switches allow an individual to slide the switch to their desired level of lighting, which uses less electricity than a switch that is either fully on or fully off. When combined with LED light bulbs, dimmer switches can help control your building’s energy costs.
A modern dimmer switch switch functions the same way as if you turn a light ON and OFF really fast. These switches are designed to work with CFLs, Halogens, and Incandescent light bulbs. But the bulbs need to be of the latest technology and must have the feature of dimming to allow it to be used with a dimmer switch.

Light sensors installed as part of a control system measure the amount of ambient light present and adjust the electric lights accordingly. Light sensors measure illuminance, which can be used to measure more than the brightness of a light source and helps with energy efficiency by ensuring no electric light is wasted.
Photocell or Photovoltaic light sensors are also called solar cells. The light sensors for photovoltaic cells respond to light levels by generating current or voltage and storing it in silicon cells for use as an emergency or alternative energy. In low light situations, photovoltaic sensors don’t generate current. Photovoltaic cells are small and generate low wattage, but they commonly come in panels for large amounts of current. These light sensors respond only to light visible on the human scale.
Motion Sensors & Proximity Sensors
Motion sensors for lights are controlled by sensing motion and are light-dependent sensors are inexpensive and commonly used for gauging and responding to light levels. Proximity light sensors respond to changes in infrared light to detect motion or proximity to another object.

4. DALI Lighting Control System
The “Digital Addressable Lighting Interface” (DALI) is a communication protocol for building lighting applications and is used for communication between lighting control devices, such as electronic ballasts, brightness sensors or motion detectors.
Using a two-way method, the system enables the user to communicate with LED drivers and ballasts, and vice versa, via a DALI controller, which is typically a computer system with software or dimming controller.
DALI is also an international standard for lighting communication, which means that all components of a lighting system marked with the DALI logo, even from different manufacturers, can work with one another. This standard was created to ensure compatibility and interchangeability across lighting systems in the industry.

5. Networked Lighting Control
The most advanced type of lighting control is a networked system, which can be part of a Building Automation System (BAS) package or designed as a stand-alone system. Networked lighting control allow the operators to control the lights from their computers or handheld devices that contain the lighting system software. Operators can turn lights on and off and set timers to control the lights. Advanced software programs can even store data and create usage charts so that energy usage can be precisely monitored.
