02 THE CHALLENGE

THE ORIGIN OF INFINITY® TECHNOLOGY

The story of INFINITY® technology started in 2010 when GVA Lighting was approached with an unusual request to help delineate the tallest office building in Canada, standing 298 meters (978 feet) tall. The project had strict requirements and limitations placed.

The architect required: • No penetrations into the building • No unnecessary lengthy wiring on the facade of the building And luminaires had to be: • Industry-leading in surface brightness • Small with a clean aesthetic • Color-changing • Highly reliable • Reasonably priced

03 DELIBERATION

THE BRAINWORK BEHIND THE TECHNOLOGY Our analysis, experiments, and extensive engineering brainstorming revealed the following: • 18 mid-power LEDs per 300 mm (1 ft) module with a maximum power consumption of 5 W per module creates desirable luminance and uniformity • Low voltage design is not applicable; at 5 W per 300 mm (1 ft), Class 2 circuits can only power 6 linear meters (20 ft) of lighting, and Class 1 with a reasonable cable gauge - up to 30 meters (100 ft).

Large electrical load with low voltage power requires a large gauge wire and cables to handle high current and to minimize voltage drop Fixtures with built-in AC/DC power supplies are close to the solution; however: • They all have lifetime limitations due to temperaturesensitive electrolytic capacitors • Physical dimensions are larger than desired • Length is still limited to approximately 92 meters (300 ft) The luminaire components luminaire size: • Cable • Connectors • Inductors • Electrolytic capacitors

the

The Conclusions we made: •

To meet size requirements, cable diameter should be 7~9 mm (0.35 in) or smaller

•

To avoid excessive cabling we must transfer the current through the modules (through-wiring)

•

The light source must be modular and completely environmentally protected

•

A centralized remote power supply is ideal for system reliability and maintenance

06 THE FORMULA

THE RESULT ATTRIBUTED TO INFINITY® TECHNOLOGY THE INFINITY® FORMULA = OHM'S LAW

CONSTANT POWER

A simple formula for success emerged.

1. To keep the luminaire small, we had to reduce the current to keep the connectors and cables small !

2. Since the brightness (total wattage) could not be reduced we had to increase the voltage !

The industry's psychological barrier regarding traditional line voltage (120 V AC in North America, 230 V AC in Europe) limits the ability to achieve much-desired long run lengths.

Concluding that the system voltage has to be higher than standard line voltage, it was determined that a range between 250 V and 600 V is most suitable; this is within the Low Voltage limits of both North America (600 V AC or DC) and Europe (1000 V AC or 1500 V DC by Low Voltage Directive and IEC standard).

VOLTAGE

CURRENT

Complete DC systems avoid bulky AC components AND achieve better electrical and optical parameters.

4. 380 V DC was selected !

It is the sweet spot •

Within IEC standards, CEC & NEC for Low Voltage Classification Provides a simple and effective design of AC/DC boost converters because the selected DC voltage is higher than the peak AC voltage (186 V in North America and 354 V in Europe) Within the standard voltage rating of commonly used electronic components, which are readily available & have a reasonable cost The voltage of choice for new Data Centers and Microgrids by Emerge Alliance

3. Voltage should be DC, not AC !

Since many line voltage luminaires feature built-in AC/DC power supplies with bulky inductors and capacitors, they cannot maintain the small size required.

More advanced line voltage luminaires feature ‘compact AC drivers’ which do not require large transformers or electrolytic capacitors; however, these lumianires still have limitations. These systems are prone to high flicker index and THD and they have difficulty with high speed control.

INFINITY® = TECHNOLOGY = APPLY HIGHER VOLTAGE+DIRECT CURRENT TO ACHIEVE: • • • •

long lighting circuits increase system reliability minimize lighting equipment dimensions huge savings on wiring and installation

07 THE CHALLENGE

THE ACHEIVEMENT OF INFINITY® TECHNOLOGY We achieved: • • • • • • • • •

Long lighting circuits of 300+ meters (1000+ feet) can be fed from a single power and data input point Compact luminaire size by eliminating bulky capacitors required for AC/DC converters Small cables and connectors resulting in small form factor Increased fixture reliability and lifespan by eliminating temperature sensitive electrolytic capacitors (typically rated for 4,000 hours @ 80°C) Compatibility with renewable energy sources such as solar and wind Energy saving by eliminating AC/DC conversion, which typically represents 10~15% of system losses Ideal Power Factor 1.0 or 0.99 for AC/DC source Lower system cost with fewer, higher-wattage power supplies Lower system cost with savings on cabling and connections with through-wiring design

The Problem was solved! We can build very long lighting circuits fed from a single power and data input point.1
