…When a control method is introduced for each luminaire, individual control is possible by simply mounting an LED DALI Dimming Module (LDM) on the secondary side of the LED lighting power supply. As it does not cause communication problems, it is judged that this communication method is suitable for mixing with the light line.

…When the partition in the office frequently changes, when the control zone is modified, it is possible to configure the control zone simply by modifying the program without the need for a separate piping wiring modification work.

…By creating an individual office space, it provides a creative office environment, and automatically turns off and dimming by absence sensor (eg: 70% dimming in absence of 30 minutes, 30% dimming in absence of 60 minutes, after 2 hours). It is possible to reduce the electric energy wasted.

…Compared to the On/Off control method for each circuit working time, DALI communication type LED Dimming Module is an essential option as a system that can reduce electric energy in detail and is the top priority item of LED lighting installation buildings recently.

…Depending on the installation location, the sensor function is a mixture of two sensor functions… The window is mainly focused on the photo sensor, and in the office area, the control function is applying by mixing two functions of photo and occupancy sensor. The photosensitive compensation function adjusts the illuminance appropriately while sensing the ambient light brightness when the illuminance level is 80-90%, which maintains the light brightness of the light, which can maximize the efficiency of lighting while meeting the required illumination of the office. The ability to maintain about 85% continuously.
