7 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) h 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. h peak 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 h peak = 1.3 i v data sheet = 3500 cd therefore i v avg = (10 ma/10 ma) (1.3)(3500 cd) = 4550 cd
