Description

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 HDSP-

4820/4830/4840/4850 and HLCP-

J100 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 emit-ting 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 (HDSP-4840) 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 maxi-mum V F values for driver circuit design and maximum power dissipation may be calculated using the V FMAX models:Standard Red HDSP-4820 series

V F MAX = 1.8 V + I Peak (10 ?)

For: I Peak≥ 5 mA

AlGaAs Red HLCP-J100 series

V F MAX = 1.8 V + I Peak (20 ?)

For: I Peak≤ 20 mA

V F MAX = 2.0 V + I Peak (10 ?)

For: I Peak≥ 20 mA

HER (HDSP-4830) and Yellow

(HDSP-4840) series

V F MAX = 1.6 + I Peak (45 ?)

For: 5 mA ≤ I Peak≤ 20 mA

V F MAX = 1.75 + I Peak (38 ?)

For: I Peak≥ 20 mA

Green (HDSP-4850) series

V F MAX = 2.0 + I Peak (50 ?)

For: I Peak > 5 mA

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:

I V AVG = (I F AVG/I F AVG DATA

SHEET)ηpeak)(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.

ηpeak is the relative efficiency at

the peak current, scaled from

Figure 4 or 10.

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-

4830 driven at 50 mA peak 1/5

duty factor?

I F AVG = (50 mA)(0.2) = 10 mA

I F AVG DATA SHEET = 10 mA

ηpeak = 1.3

I V DATA SHEET = 3500 μcd

Therefore

I V AVG = (10 mA/10 mA)

(1.3)(3500 μcd)

= 4550 μcd
