Lighting control system

A light management system is a system for controlling a lighting system. There are appropriate systems of various manufacturers both for the control of indoor and outdoor lighting. Your task is to either adjust the backlight level of the plant to the prevailing environmental conditions or to run a predetermined program. Through various control functions or programs of comfort for a user and increases the energy to the other can be saved.

Light Management Systems in indoor lighting

Prerequisite for the use of a light management system for interior lighting is a good dimming of the light source, this also must be designed for a high switching frequency. Normally you also have an electronic ballast is required. The basic structure consists of a controller, which controls the operation of devices via an interface (eg, 1 -10V, Digital Serial Interface (DSI ), Digital Addressable Lighting Interface ( DALI) ). There is also the possibility of sensors and switches to embed a user control allow. As sensors are light intensity and Bewegungs-/Präsenzsensoren or a combination of both are used. This makes it possible to realize a daylight - and presence control. In the daylight control the lighting system is adjusted according to the natural illumination to obtain a constant brightness in the room. A presence control switches off the lighting system or dims them down to a low base level, if there are no people in the room are. If a person enters the room, upon detection of the light intensity is increased back to the normal level by the controller through the sensor. Through each of these two possibilities, energy can be saved, the maximum saving effect is achieved with a combination of both.

Light Management Systems in street lighting

As for interior lighting, there are ways to install a lighting management system for street lighting. The main purpose is the saving of electric energy. In general, a separate controller is installed here for each light. These controllers are either completely independent or networked with each other, for example by radio or via Power Line Communication ( LON). Due to the different controller settings can be made. This allows a dimming via the natural lighting levels or power reduction during night hours only. In combination with a push button or motion sensor can dim up the lighting system back to full illumination level if necessary. It is also possible to stabilize over the life of a lamp or an LED module returning light power to obtain a constant optical power output over the entire lifetime.
