INTERVIEW enough, we’ve found the technology development for these two different markets to be very complimentary. For example, we initially developed our LEDSense® Thermal Management technology for flashlights, which allowed us to realize significant light output from a flashlight with minimal heat-sinking during the typically short “ontime” that a flashlight experiences, while also ensuring that the system does not overheat or degrade the LEDs if left on for a longer period of time—either purposely or by accident. Now we use LEDSense® technology in our illumination engines to assure long-term lumen maintenance in potentially adverse conditions such as a landscape lighting fixture being accidentally covered in dirt and not able to dissipate heat. With LEDSense®, the system will simply pull back on power until the fixture us uncovered. We expect to continue to leverage core technology like this in more and more lighting applications, leading to significant growth for many years to come. What challenges do you foresee in our industry? The legacy infrastructure for lighting is quite diverse and complex. The various dimming schemes and power sources (both line and low voltage) represent a huge challenge. LEDs react nearly instantaneously, which is often a curse. The slow response time of incandescent sources prevents many problems from becoming apparent. When LEDs are used the often messy state of the electrical infrastructure becomes evident. The LED light source is usually faulted. We as an industry must figure out how to ensure an experience which is cost-effective and satisfying. Do you have any tricks up your sleeve? We have a lot of technology we have not deployed in products. There are methods of LED control that get to the basic physics of how LEDs operate that would be exciting to implement, but it’s probably too soon. Other features such as making the light source part of the information superhighway are exciting. Since LEDs are very controllable, and require drive electronics anyway, taking the next step of integrating lighting into a building information system is not a significant stretch. This can offer significant new features from tuning light to meet the demands of the users to a higher level of control for the purpose of conserving energy. By integrating technology such as wireless control into our LED engines and modules, we can even bring these new features to older buildings. Is there anything that you have not accomplished yet, that you have your sights on accomplishing in the near future? I think we as a team want to see TerraLUX recognized as a leader in LED lighting. As my high school physics teacher implied, we need to turn our “potential” into “kinetic.” Personally, having started the Company back in 2003 it has been very satisfying to see the original vision turned into products, patents and perhaps most importantly-jobs. ■ <strong>EEWeb</strong> | Electrical Engineering Community Visit www.eeweb.com 8 FEATURED INTERVIEW
