Lexel LED DLM system is designed for general lighting applications in the professional market for retail, hospitality and offices, enabling the creation of various atmospheres with changing tones of white light and different colors from a single light source. Lexel LED DLM uses a combination of RGBW LEDs to produce high CRI white light.
Lexel LED DLM is a system with an architecture based on two modules communicating through a proprietary lighting protocol (T-Bus):
- External Protocol Translator (accepts DMX or DALI) and Power Supply
- Light Generation Module (light engine)
Applications:
- Retail outlets – windows, wall washers, leisure areas, focus islands and retail concept stores
- Office areas – public spaces like presentation rooms, boardrooms and canteens/restaurants
- Hospitality – lobbies, reception areas, restaurants, bars and elevator halls
- Recreation – museums, galleries, theaters and other places of interest
