National and Nuventix Introduce New Reference Design for LED Bulbs
Complete Electronic Drive and Thermal Management Design for LED Bulbs Speeds and Simplifies Replacement of Conventional Bulbs
The new LED electronic drive and thermal management reference design will be demonstrated in Nuventix’s booth #3260 at the Lightfair International conference in
LED replacement bulbs typically require four different design components: the LED, electronic drive board, thermal management system and optics. Integrating these complex design components to produce an efficient and high-performance LED bulb system can be challenging.
A new reference design featuring National Semiconductor’s electronic drive board together with the SynJet(R) cooling module from Nuventix provides lighting designers with a complete electronic drive and thermal management design for high-performance LED replacement bulbs.
The SynJet thermal management module from Nuventix features a synthetic jet cooling technology that utilizes turbulent pulses of air generated from an electromagnetic actuator to reliably and efficiently cool the LED. It is compatible with standard bulb form factors including MR16 and PAR38.
“SynJet cooling by Nuventix is essential to optimize lumen output and LED reliability for LED lighting,” said
The electronic drive board from National Semiconductor features the LM3429 buck-boost LED driver and LM2842 voltage regulator systems. The LM3429 system provides a constant current to the LEDs from input voltage rails of 9V to 36V, includes analog dimming capability and is configured to drive up to 12 series-connected LEDs. The LM2842 system powers the SynJet electromagnetic actuator. The form factor of the electronic drive board is compatible with the Nuventix SynJet MR16 and PAR38 modules.
“This new reference design enables lighting designers to quickly, easily, and reliably design a thermal and electronics drive system for any MR16 or PAR38 form factor LED bulb,” said
The LED electronic drive and thermal management reference design is available now for download from www.national.com/led.
