Purpose of the lighting control system
The conditions of internal natural lighting, occupancy and use of a space change during its operation.
The control of the lighting system, which is achieved either manually or automatically, must achieve the following:
- the functionality and adaptability of the space
- energy saving
- visual comfort to the users of the space
- to cover the operating regulation regarding lighting
- to create a dynamic or dramatic environment is needed
Different lighting installations are needed for different activities or functions.
For example, a lecture hall is often used to present a topic with power point and slide show, so the light condition of the room should be low, thus letting the audience see the slides projected on the screen clearly and comfortably.
When the lecture continues without the use of slide projection, a greater brightness of the space is needed to make the communication of the participants pleasant and effective.
When the audience enters a cinema and must find their seats to sit, the lights must be on, but they must be turned off when the play begins.
It is necessary in a space to provide different alternating lighting for different functional uses. The lighting system must adapt to the changes that can be made in a space, such as office spaces where their configuration can change.
Energy efficiency is one of the important issues that are taken seriously when designing the lighting control system. A very significant percentage of the energy of buildings is consumed by lighting systems.
The lighting control system provides the necessary lighting only in the areas and time periods required and thus contributes to energy savings.
The main commands given by the control system to the lamp for this purpose are the on/off commands and commands to increase or decrease its intensity.
The importance of lighting in our environment
Lighting is one of the most important factors that contribute to creating a creative and comfortable environment for working and living. It is one of the most important environmental factors that affect the satisfaction of those who live in residential buildings. Lighting is also an environmental factor that affects the productivity of workers. Different people also prefer different levels of lighting.
When with the lighting control system, the visible environment can be adapted to the individual requirements and wishes of the user, this increases the satisfaction of the user and makes his stay and his work more comfortable and efficient.
Lighting has become a matter of legislation in many countries.
Typical issues of concern are:
- establish specifications and standards for certain types of premises and activities to ensure efficiency.
- establishing standards to ensure personal safety and security of premises
- establishing standards regarding the use of technology and lighting systems that ensure energy efficiency.
Creating the desired aesthetic effect in spaces in a practical way has been a major driver of the market for lighting control, although energy management plays an ever-increasing role.
The lighting system can be controlled to offer a balance to the various light sources to ensure a pleasant visual environment or to transition from one light state to another.
Depending on the functional purpose of a space, lighting systems can be controlled to provide "comfort" in the sense of relaxation or a pleasant visual environment. Lighting systems can also in special entertainment areas be controlled so as to create a dramatic and dynamic environment.
