PRODUCT PREVIEW
Adjusting dc drive current to accommodate a desired Luminous Intensity:
The equation to determine the dc drive current required to produce a desired Luminous Intensity for the Intensity
Rank H is given below. The graphic for the Rank H is shown:

(ma)
ID = m x IV + b where m = 0.17, b = -2.512, IV is the value of Luminous Intensity in milli-candela
Example: Determine the dc Drive Current required to produce a nominal Luminous Intensity of 200 mcd.
ID = 0.17 x 200 – 2.512 = 31.5 ma
The resulting power dissipation is: ~110mW (Read the forward voltage from the “L” graph of ID vs VF)
The junction temperature rise is less than 20°C above ambient (see junction temperature rise graph).
