Intelligent lighting is a lighting technology designed for energy efficiency. This may include high efficiency fixtures and automatic controls that make adjustments based on conditions such as availability of occupancy or daylight. Lighting is a deliberate light application to achieve some aesthetic or practical effect. This includes task lighting, accent lighting, and general lighting.

Energy consumption
19% of the world's energy use is used for lighting, and 6% of the world's greenhouse emissions come from energy used for lighting. In the United States, 65 percent of energy consumption is used by the commercial and industrial sectors, and 22 percent of this is used for lighting.
Minimize energy usage
Intelligent lighting is a good way that allows to minimize and save light by allowing homeowners to control cooling and remote heating, lighting, and equipment control. This ability saves energy and provides a level of comfort and convenience. From outside the traditional lighting industry, the success of future lighting will require the involvement of a number of stakeholders and stakeholder communities. The concept of intelligent lighting also involves the use of natural light from the sun to reduce the use of manmade lighting, and the simple concept of people who turn off lighting as they leave the room.

Primary techniques
Smart lighting control
The use of automatic light dimming is an aspect of smart lighting that serves to reduce energy consumption. Manual light dimming also has the same effect of reducing energy use.
Sensor use
On the paper "Energy savings due to occupancy sensors and personal control: pilot field studies", Galasiu, AD and Newsham, GR have confirmed that automated lighting systems including occupancy sensors and individual (personal) controls are suitable for open plan office environments and can save significant amounts energy (about 32%) when compared to conventional lighting systems, even when the installed lighting power density of the automatic lighting system is ~ 50% higher than that of conventional systems.
Components
The complete sensor consists of a motion detector, an electronic control unit, and a controllable switch/relay. Motion senses detector and determine if there are occupants in space. It also has a timer that signales to the electronic control unit after a period of inactivity is set. The control unit uses this signal to activate the switch/relay to turn the equipment on or off. For lighting applications, there are three main types of sensors: passive infrared, ultrasonic, and hybrid.
Daylight sensing
In response to natural lighting technology, the day-to-day automatic response system has been developed to reduce energy consumption. This technology is very helpful, but they have its downfall. Over and over, frequent and frequent turns and turning of lights, especially during unstable weather conditions or when daytime rates change around the redirect illumination. Not only disrupt the occupants, it can also reduce the lamp life. Variations of this technology are 'switching' or 'dead-band' photoelectric controls that have multiple illuminations that are diverted to reduce disturbed occupants.
Occupancy sensing
Intelligent lighting utilizing occupancy sensors can work in conjunction with other lighting connected to the same network to adjust the illumination per different conditions. The table below shows the potential power savings from the use of occupancy sensors to control lighting in different types of space.
Ultrasonic
The advantage of ultrasonic devices is that they are sensitive to all types of motion and there is generally zero coverage gap, because they can detect motion not in line of sight.

Automatic emergency ballast-lighting for fluorescent lighting
The function of a traditional emergency lighting system is the minimum level of illumination supply when a line voltage failure occurs. Therefore, they must store energy in the battery module to supply the lamp in case of failure. In such lighting systems, internal damage such as excessive battery charging, damaged lights and circuit failures start to be detected and repaired by specialist workers.
For this reason, intelligent lighting prototypes can check their functional status every fourteen days and discard the results to the LED screen. With this feature they can test themselves checking their functional state and display their internal damage. Also the cost of care can decrease.
Overview
The main idea is the replacement of simple line voltage sensing blocks that appear in traditional systems by more complex systems based on microcontrollers. This new circuit will assume the function of voltage sensing and inverter activation, by one side, and supervision of all systems: lamp and battery state, battery charging, external communication, correct operation of the power stage, etc., On the other hand.
This system has great flexibility, for example, it may communicate multiple devices with a master computer, which will know the status of each device at any time.
New emergency lighting systems based on smart modules have been developed. Micro-controllers as a control and surveillance device ensure improved installation security and maintenance cost savings.
Another important advantage is the cost savings for mass production especially whether the microcontroller with the program in the ROM memory is used.
Intelligent lighting ecosystem
Smart lighting systems can be controlled using the internet to adjust the brightness and lighting schedules. One technology involves intelligent lighting networks that assign IP addresses to light bulbs.
Forwarding information with intelligent light
Schubert predicts that the revolutionary lighting system will provide new means for sensing and broadcasting information. By blinking too fast for any human to notice, the light will retrieve data from the sensor and take it from room to room, reporting information like everyone's location in a high security building. The main focus of Future Chips Constellation is intelligent lighting, a revolutionary new field in photonics based on an entirely perceptible source of light in terms of factors such as spectral content, emission patterns, polarization, color temperature, and intensity. Schubert, who leads the group, says intelligent lighting will not only offer better and more efficient lighting; it will provide "a completely new function."
Progress in photonics
The advances in Photonics have transformed society as electronics have revolutionized the world in the last few decades and will continue to contribute more in the future. From statistics, the North American optoelectronics market grew to more than $ 20 billion in 2003. The LED (light-emitting diode) market is expected to reach $ 5 billion in 2007, and the solid-state lighting market is estimated to be $ 50 billion in 15- 20 years, as stated by E. Fred Schubert, Wellfleet Senior Distinguished Professor of Future Chips Constellation at Rensselaer.
