These 10-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 HDSP4820/4830/4840/4850 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.

Notes: 1. The bar graph arrays are categorized for luminous intensity. The category is designated by a letter located on the side of the package. 2. The dominant wavelength, λd, is derived from the CIE chromaticity diagram and is that single wavelength which defines the color of the device. 3. The HDSP-4832/-4836/-4840/-4850 bar graph arrays are categorized by dominant wavelength with the category designated by a number adjacent to the intensity category letter. Only the yellow elements of the HDSP-4832/-4836 are categorized for color. 4. Electrical/optical characteristics of the High-Efficiency Red elements of the HDSP-4832/-4836 are identical to the HDSP-4830 characteristics. Characteristics of Yellow elements of the HDSP-4832/-4836 are identical to the HDSP-4840. Characteristics of Green elements of the HDSP-4832/-4836 are identical to the HDSP-4850. 5. Reverse voltage per LED should be limited to 3.0 V max. for the HDSP-4820/-4830/-4840/-4850/-4832/-4836 and 5.0 V max. for the HLCP-J100.

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-4820) bar graph array LEDs use a p-n junction diffused into a GaAsP epitaxial layer on a GaAs substrate. The AlGaAs Red (HLCP-J100) bar graph array LEDs use double heterojunction AlGaAs on a GaAs substrate. HER (HDSP-4830) and Yellow (HDSP4840) bar graph array LEDs use a GaAsP epitaxial layer on a GaP substrate. Green (HDSP-4850) bar graph array LEDs use liquid phase GaP epitaxial layer on a GaP substrate. The multicolor bar graph arrays (HDSP-4832/4836) have HER, Yellow, and Green LEDs in one package. These displays are designed for strobed operation. The typical forward voltage values can be scaled from Figures 5 and 11. These values should be used to calculate the current limiting resistor value and typical power consumption. Expected maximum VF values for driver circuit design and maximum power dissipation may be calculated using the VFMAX models:
Standard Red HDSP-4820 series VFMAX = 1.8 V + IPeak (10 Ω) For: IPeak ≥ 5 mA AlGaAs Red HLCP-J100 series VFMAX = 1.8 V + IPeak (20 Ω) For: IPeak ≤ 20 mA VFMAX = 2.0 V + IPeak (10 Ω) For: IPeak ≥ 20 mA HER (HDSP-4830) and Yellow (HDSP-4840) series VFMAX = 1.6 + IPeak (45 Ω) For: 5 mA ≤ I Peak ≤ 20 mA VFMAX = 1.75 + IPeak (38 Ω) For: IPeak ≥ 20 mA Green (HDSP-4850) series VFMAX = 2.0 + IPeak (50 Ω) For: IPeak > 5 mA
Where: IVAVG is the calculated time averaged luminous intensity resulting from IFAVG. IFAVG is the desired time averaged LED current. IFAVG DATA SHEET is the data sheet test current for IVDATA SHEET. ηpeak is the relative efficiency at the peak current, scaled from Figure 4 or 10. IV DATA SHEET is the data sheet luminous intensity, resulting from IFAVG DATA SHEET. For example, what is the luminous intensity of an HDSP4830 driven at 50 mA peak 1/5 duty factor?
Figures 4 and 10 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:
IFAVG = (50 mA)(0.2) = 10 mA
IVAVG = (IFAVG/IFAVG DATA SHEET)ηpeak)(IVDATA SHEET)
IVAVG = (10 mA/10 mA) (1.3)(3500 µcd) = 4550 µcd
IFAVG DATA SHEET = 10 mA ηpeak = 1.3 IV DATA SHEET = 3500 µcd Therefore
