More comfort and new ideas

With the DL50 LED, intelligent control electronics ensure that precisely the right quantity of light is emitted to the specific target at the right time, in turn improving energy efficiency and the quality of life in public spaces.

DL50 LED luminaires completely exploit the potential of mature LED technology. Thanks to intelligent control, luminaires can be set individually or as groups for specific lighting tasks, and dimming values and durations can be specified, meaning operation is accorsing to requirements and with optimised energy consumption.

Basic functional package

• night-time reduction at times of low traffic density to 50% rated luminous flux, at less than 50% rated power via one control wire

Plus functional package

• intelligent, self-sufficient light management system for lighting according to requirements based on individual programming
• CLO 2.0
• Electronic type plate and automatic data exchange for smart performance updates

Premium functional package

• Maximum flexibility and efficiency via integration into intelligent, networked light management and monitoring systems

CLO 2.0 - The revolution of CLO

Constant lumen output (CLO) has been one of the main control features with modern urban lighting during the last years. Like the name already says this function ensures a constant lumen output at a specified level by dimming at the beginning of the operation time and power correction with continuing lifetime.

In the past CLO meant a static curve for correction of wattage, predefined at laboratory conditions with 25°C and 100 % operation mode of the luminaire.

The new CLO 2.0 is a patented solution that takes into account real life conditions where wind, rain, ambient temperatures and dimming modes have an impact on the temperature of LEDs and components - which in turn is a significant factor for the efficacy and lifetime of luminaires.
With CLO 2.0 built-in sensors measure the temperature of the components and the ECG decides how much voltage the luminaire needs to reach a defined lumen package.

That means:

• Higher efficacy, longer lifetime
• Up to 6% energy and CO2 savings
• Lower energy costs
• A much more exact correction of the luminous flux
