LED Indicators Add Modern Touch To New Appliances

TORRANCE, CA - August 26, 1997 - As we approach the end of the millennium, sleek, modern, even futuristic appliance designs are becoming more and more the standard. One effect of this trend is to cause design engineers to search for components which will complement their concept of the finished appliance.

"For our Touch Top cooktop, we were looking for something that would give us a very graphic indication of increasing heat," says Bob Lewis, Director of Product Development for DACOR, a California manufacturer of modernistic cooktops, ovens and ventilation systems. "LEDtronics®’ bar-graph LEDs (light emitting diodes) provide a sleek, slender ribbon of red light which was perfect for our design objectives, but offered other important attributes as well."

According to Lewis, the temperature indicator needed to comply with space constraints and stand up to heat produced by the elements without requiring significant insulation. Unlike incandescent bulbs, LEDs are far less susceptible to heat, and because they have a significantly longer life span, it’s likely the indicator will last the life of the appliance. LEDtronics®’ compact 10-LED bar graph also fit in nicely with the sleek, angular nature of the product design.

"To meet DACOR’s requirements, we re-designed our standard polycarbonate housing for the bar-graph LED to shield each side so there would be no light bleed-through from one cell to another. We also created a special alignment jig to be used in manufacturing which would yield a perfectly straight line of light, and worked with them on aspects like the specific color, angle of illumination and, of course, cost," says Pervaiz Lodhie, president of LEDtronics®. "Many of these kinds of design projects require some custom engineering and prototyping, but when you’re determined to provide the best possible solution, you do whatever it takes."

The DACOR Touch Top is popular among both architects and kitchen designers. Its sleek design, one smooth piece of glass with a beveled perimeter, interfaces with the countertop. With the touch command center, there is no separate control panel or protruding knobs to disturb the smooth symmetry of the glass.

"We’re aiming this product at a very specific, high-end niches," says Lewis. "LEDtronics® worked closely with us to meet our needs and help us realize our vision of what the Touch Top could be."
