During this session the first physical prototypes of DC/DC, LVPS, DALI and Control were merged to a running system by NPC and TRI. Besides that, DTU showed a demonstrator for AC/DC-conversion with high efficiency. In a next step PFC-functionality should be included. This was intensively discussed on the flipchart in parallel to soldering and measuring and all project-partners from WP1-WP5 were involved. At lunch-time and begin of the official LEDLUM technical meeting there was LiL (Light in LED) and closed-loop regulation allowed smooth dimming. Although size- and cost-targets are not fully met with this early demonstrator it is an ideal base for further improvements of the concept and components.
