How Substrate Materials Affect LED Reliability

The solid-state lighting industry continues to develop LEDs with higher lumens per watt, in alignment with Haitz Law, which states that the cost per lumen falls by a factor of 10 every decade and the amount of light generated per LED increases by a factor of 20. These advancements are driving the need for packaging and thermal substrate technologies that deliver better thermal management, are more reliable, and are cost-efficient.

Brighter, More Efficient LED-Based Lighting

Code 3’s TriCore is an LED-based optical lighting technology that is 2X brighter than other technology currently on the market using only 1/3 the power of conventional lighting systems, yielding higher watt-for-watt efficiency. The brightness and efficiency are achieved through a unique design that combines an LED chip with an optical-based lens system. The LED chip (die) system overcomes all limitations imposed by pre-packaged LEDs. Moreover, the optical-based lens system removes the inefficiencies within reflective-based lighting technology. These two technological advances competitively separate Tri- Core from any other lighting technology on the market today.

Method of Simultaneously Refreshing all Pixels In a Display

Matrix-addressed displays, which include LCDs, LEDs, and almost every kind of display except the CRT, are currently refreshed one row or one column at a time. This is required for all digitally controlled displays and causes bandwidth limitations due to the high resolutions present in today’s displays. This bandwidth limitation is usually compensated for by using a faster processor, usually at increased expense and power consumption in the display.

VPX: The State of the Ecosystem

You can never have too much bandwidth. High-speed processing and growing amounts of data to be communicated require generous bandwidth from the board level to the I/O. VPX, with a backplane connector system supporting 6.25 Gb/s in a switched fabric architecture, is the latest generation of VMEbus and offers new levels of performance for embedded computer systems. VPX systems are designed for flexible application of demanding highspeed protocols, such as 10G Ethernet, RapidIO, InfiniBand, and Hyper Transport protocols, in ground, aerospace, and marine applications.
