Introduction § To maximize intelligent LED controls, Dellux developed IP to provide luminaires longer life, lower energy for less cost. § These control capabilities can be integrated in every luminaire cost effectively § Dellux IP provides added value to your Customers 9

Common LED Lighting Solutions All LEDs dim as they age, Lumen depreciation has to be considered. Manufacturers add more LEDs to comply with IES/CIE Standards & over light to ensure Safety, Security & Vision Clarity to maintain minimum required lighting levels until the end of Luminaire Service Life. Off LEDs Don’t Degrade Over Lighting wastes energy 10

Technology Luminaires with Dellux embedded LED chain management control, have extended operational life, and are the most energy efficient luminaires, when compared against all other options. Luminaire LED chains are individually controlled by a microcontroller which; a) Varies & alternates the numbers of activated LED chains needed to maintain the designed lighting levels, and a) Equalizes the time each chain is used. 16

3 Design Methodologies 1. “LEDs In a box” Most common method 2. “Current Compensation” An energy-saving alternative 3. Dellux “LED Chain management Control” Greatest energy savings, longest life, using fewer LEDs with sustained light levels. 17

Dellux LED Chain Control Application Simple & Low Cost • Bi-Level control • Alternates LED chains for uniform aging of each chain. • Area lighting, Street, Stairwell, Parking etc. Complex & Higher Performance • Continuous light operation 12 to 24 hours a day. • Service Life of up to 20 years. • Tunnel, Street, Parking, Offices, Billboards etc… 18

Dellux LED chain control application Simple & low cost DAY 1 Photocell Bi-Level turns OFF half the LED chains, reduces energy -50% + alternates every 24 hours for uniform LED degradation & extension of service life. Chain 1 2 OFF OFF ON ON Tx ON ON OFF OFF DAY 2 OFF OFF ON ON Tx ON OFF OFF Tx delay set by photocell/control 19

Technology Complex & higher performance LED degradation is compensated by controlling the number of LEDs turned On while maintaining the LED current constant during the whole luminaire lifetime. At start-of-life, a certain numbers of LEDs are turned On in order to reach the designed luminosity level; the number of LEDs On is then gradually increased, therefore maintaining a constant luminosity “Lr”. A further LED usage rotation mechanism ensures that, on average, all LEDs in the luminaire are turned On for the same duration. The essential advantage of this method is that at the end of service life, all LEDs will in fact have been On for an average duration “Ton” lower than “Tlife”, since at any given time during the luminaire lifetime only a portion of the available LEDs are turned On. Therefore, LED Lumen Maintenance decreases slower than in a luminaire where all LEDs are always On. 20
