The average luminous intensity is obtained by summing the luminous intensity of each segment and dividing by the total number of segments. 2. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (International Commission on Illumination) eye-response curve. 3. Clean only by pure water, isopropanol, ethanol, Freon TF (or equivalent). o Wave Emitted Color Hi-Eff Red Green Super Red Common Anode C.C or C.A Length (nm) 635 565 660 570 585 565 635 565 Common 660 570 585 Absolute Maximum Ratings Pd If Electro-optical Characteristic If If Vf (V) Iv (cd) (Peak) (Rec) Per Dot Per Dot (nm) (mW) (mA) (mA) Min.
