Surface Mountable Seven Segment Numeric LED Display

Wed, 02/21/2001 - 8:22am
Lumex introduced a seven segment numeric LED display which is surface mountable. This device makes possible, for the first time, the design and construction of equipment and instrumentation with numeric LED readouts — on surface mount technology (SMT) boards and manufacturing processes. The Lumex 7-segment SMT LED display is ideal for a wide range of applications including timers, controllers, counters, test equipment, or virtually any system requiring a numeric display, where surface mount technology is mandated by the overall design and cost parameters.

This new display is based on a low-profile, insert molded flat lead frame package which stands 3.3 mm (0.130) off the surface of the circuit board. The package measures 19 mm (0.748) high by 12.7 mm (0.500) wide, with a 14.22 mm (0.56) high numeric character. Each of the seven segments is individually addressable, to create all digits from 0 through 9, plus several additional characters. A trailing decimal point is also included.

Standard color choices include state-of-the-art GaP green (565 nm) and GaAsP high-intensity red (635 nm), with optional blue and yellow available. Light output levels are as high as 3200 mcd with a forward current of 10 mA. Units can be ordered with a choice of common cathode or common anode configurations.

Custom versions of the 7-segment numeric SMT LED display are available as well, with a choice of face mask and segment colors, lead times, and reflectors.
