The LS1 series side-emitting, true-right-angle, surface-mount LEDs released by Marktech Optoelectronics are suitable for lightguide applications. They come in a 4 × 4-mm package, have a 2.4-mm-diameter lens and are industrial-temperature-rated from 240 to 100 °C. An integrated reflector provides a viewing angle of 120°. Available colors are white, blue, green, blue-green, yellow, red-orange and red. Luminous intensities are up to 900 mcd. Low power consumption also makes the LEDs suitable for backlighting, optical indicators, automotive applications and consumer products.
