HLCP-J, HDSP-, HDSP- & HDSP- -Element Bar Graph Array Data Sheet Description These -element LED arrays are designed to display information in easily recognizable bar graph form. The packages are end 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-/// and HLCPJ each contain LEDs of one color. The HDSP-/ are multicolor arrays with High Efficiency Red, Yellow, and High Performance Green LEDs in a single package.

Electrical/Optical These versatile bar graph arrays are composed of ten light emitting diodes. The light from each LED is optically stretched to form individual elements. The Red (HDSP- ) bar graph array LEDs use a p-n junction diffused into a GaAsP epitaxial layer on a GaAs substrate. The Al- GaAs Red (HLCP-J) bar graph array LEDs use double heterojunction AlGaAs on a GaAs substrate. (HDSP- ) and Yellow (HDSP-) bar graph array LEDs use a GaAsP epitaxial layer on a GaP substrate. Green (HDSP- ) bar graph array LEDs use liquid phase GaP epitaxial layer on a GaP substrate. The multicolor bar graph arrays (HDSP-/) have, Yellow, and Green LEDs in one package. These displays are designed for strobed operation. The typical forward voltage values can be scaled from Figures and. These values should be used to calculate the current limiting resistor value and typical power consumption. Expected maximum V F values for driver circuit design and maximum power dissipation may be calculated using the V FMAX models: Standard Red HDSP- series V F MAX =. V + I Peak ( ) For: I Peak ma AlGaAs Red HLCP-J series V F MAX =. V + I Peak ( ) For: I Peak ma V F MAX =. V + I Peak ( ) For: I Peak ma (HDSP-) and Yellow (HDSP-) series V F MAX =. + I Peak ( ) For: ma I Peak ma V F MAX =.7 + I Peak ( ) For: I Peak ma Green (HDSP-) series V F MAX =. + I Peak ( ) For: I Peak > ma Figures and allow the designer to calculate the luminous intensity at different peak and average currents. The following equation calculates intensity at different peak and average currents: I V AVG = (I F AVG/I F AVG DATA SHEET) peak )(I V DATA SHEET) Where: I V AVG is the calculated time averaged luminous intensity resulting from I F AVG. I F AVG is the desired time averaged LED current. I F AVG DATA SHEET is the data sheet test current for I V DATA SHEET. peak is the relative efficiency at the peak current, scaled from Figure or. I V DATA SHEET is the data sheet luminous intensity, resulting from I F AVG DATA SHEET. For example, what is the luminous intensity of an HDSP- driven at ma peak / duty factor? I F AVG = ( ma) (.) = ma I F AVG DATA SHEET = ma peak =. I V DATA SHEET = cd Therefore I V AVG = ( ma/ ma) (.)
