NeoPac Opto: Multi-Chip Point-Light-Source LEDs Maintains 1,500 Lumens

Combining creative thinking and proactive actions, NeoPac Opto once again pushed output brightness with single-packaged, multi-chip point-light-source LEDs light engine to the new era at over 1,500 lumen maintenance.

This innovation coming from NeoPac Opto is built on NUP (NeoPac Universal Platform) technology that integrating different levels from chips, packages, modules to systems into one SSL (Solid State Lighting) platform. Combining excellent thermal management technologies, the revolutionary breakthrough of LED technology by NeoPac Opto not only has pushed the world record of power dissipation for single-packaged LEDs up to higher levels than before (30 watts) and more over, it is able to produce over 16,00 initial lumen and 1,500 maintain lumen while controlling the LED junction temperature (Tj) at 60°C to assure the LED's long life durability and maintaining its spectral characteristics.

  
Based on patented system-in-package technology approach, NeoPac Opto has created world’s smallest LEDs multi-chip (14.1mmx14.1mm) with high density luminous flux ensuring the package meets global standards for general lighting application. Through adequate thermal management techniques, NeoPac Opto developed an ultra high power 30 watt light engine with 1A operating current maintaining system thermal resistance only of 1.17°C/W (LED junction to ambient). Therefore, all NeoPac Light Engine can operate at ultra high power with high luminous flux, low junction temperature (60°C) and have outstanding performance with long reliable life.
   
Jeffrey Chen, president of NeoPac Opto, says "Due to system thermal resistance (Rja) in the LED packaging and system assembly under ultra-high-power operating conditions, those single-packaged high-power LED lighting source available in the market can only operate at most on 3 watts, and they need to be set upon a good working heat sink base to ensure its operating safety. Our system-in-package approach NeoPac Light Engine can easily handle more than 10 times in power dissipation. Most importantly, the LEDs junction temperature can be easily controlled at or under 60°C as well.
   
The breakthrough NeoPac has made could push point-light-source, single-packaged LED into crucial applications in the opto-electronic industry, and can greatly reduce the cost of commercial production. NeoPac Opto’s new generation of LED System-In-Package Platform is well protected and has applied a number of patents at various technical levels in several countries around the world.
