Marktech Introduces the Cotco LM1 Power SMT LED

Menands, New York: Marktech Optoelectronics today announced the availability of its new Power SMT LEDs. The Cotco LM1-xxx-11 Power LED series offers high reliability and is ideally suited for effect lighting applications. Being built upon high efficiency InGaAlP and InGaN technologies, they are also designed to meet the demands of automotive and outdoor applications. They can handle forward currents from 30-50mA depending on wavelength. The LM1 Power SMT series features a standard PLCC-4 package measuring 3.0 x 2.8mm and has an integrated reflector that offers a generous viewing angle of 120 degrees. Because of its low power consumption this device is also ideal for backlighting, automotive signal lighting, marker lights, display and task lighting and an ever expanding array of signage applications. The cost-per-lumen advantage of these chips makes them an excellent choice for LED applications requiring uniform illumination.
