The high-efficiency red source color devices are made with gallium arsenide phosphide on gallium phosphide orange light emitting diode. The green source color devices are made with gallium phosphide green light emitting diode. These 10-element led arrays are designed to display information in easily recognizable bar graph form. The packages are ending stackable and therefore capable of displaying long strings of information. Use of these bar graph arrays eliminates the alignment, intensity, and color matching problems associated with discrete leds. The hdsp- 4820/4830/4840/4850 and hlcpj100 each contain leds of one color. The hdsp-4832/4836 are multicolor arrays with high-efficiency red, yellow, and high-performance green leds in a single package. 1. Custom Multicolor Array Capability. Suitable for level indicators. 2. Low current operation. Excellent on/off contrast. 3. End stackable. Mechanically rugged. 4. Standard : gray face, white segment. 5. Wide Viewing Angle. RoHS compliant.
