SynJet Operating Principle

Driven by an electromagnetic or piezoelectric actuatorAir Jets Powered by an oscillating diaphragm in a cavityAir Jets Powered by an oscillating diaphragm in a cavity

Air is drawn into the SynJet on the diaphragm down strokeAir jet is rapidly expelled on the diaphragm upstroke

One opening serves as both the inlet and the outletOne opening serves as both the inlet and the outlet

Particle Image Velocimetryof a SynJet

The result is highly turbulent, high heat transfer coefficient airflow

Flows are directed exactly where needed providing either spot or system level heat removal

Thermal Management is Key to LED Life & Performance

Lifetime is reduced with increasing junction temperature (Tj)Reducing temperature of the LED by 10ºC can add 50% to their life.

LED performance is also effected by the (Tj)Luminous flux decreases with increasing Tj

LED Lighting Adoption Challanges

Initially dim, passive designs used low cost LEDs and simplified “Eco-System “

“Eco-System” for High Brightness LED Luminaires took time to develop

HB LED cost and economic downturn slowed adoption of LED Lights

Market demand for higher brightness, lower cost has fueled Nuventix market

18 months of cost reduction, luminaire design proliferation and ecosystem maturity have set the stage for accelerated deployment of High Brightness LED Luminaires

Why SynJet™ for LED Lighting?

Commercial & Retail Track & Down lights• Lowers cost per lumen by 50%• Increases light output by 2-3x• Reduces heat sink volume by 3x• Silent, reliable, conformable

Outdoor Lighting• Impervious to environmental effects

• 300,000 hours life at 85C• Lowers weight of fixture – half the weight of AL• Reduces size of fixture – 3x reduction• Reduces # of LED’s required for a given light output

Replacement Lamps• Accelerates availability of 60W or greater equivalent bulbs

• 75W and 100W equivalent bulbs 3-5 years earlier• Lowers cost of bulbs by reducing LED count

• 8 LEDs reduced to 4 means $6 cost savings

SynJet cooling provides lowest cost per lumen, brightest LED lights, smallest size, lowers cost.

Retrofit Bulb Strategy with Integrated SynJet Engine

Use standard 40 mm and 50 mm gazelle engine as cooling architecture

− Engine will integrate into retrofit lamp form factors such as PAR38, PAR30, and other form factors that can accept the standard engine

− Allows lumen output to double and have light quality and color temperature to replace incandescent/halogen based bulbs

Target Customers

− Establish a target customer list to promote the integrated SynJet engine design approach

− Reference designs and demonstration kits for PAR38 & PAR30 form factors for customers are developed and ready for evaluation

Goals

− Establish design wins with 6 OEMs in next 3 months

− Enable OEMs to develop retrofit bulbs with integrated SynJet engine for production 1st half of 2011
