2. forward operating voltage VF: the operating voltage that provides in the parameter list is to obtain under given forward current, generally records when IF=20mA, and VF is at 1.4~3V for light-emittingdiode forward operating voltage, and when ambient temperature raises, VF will descend.
3.V-I characteristic: the voltage of light-emittingdiode and the relation of electric current, during less than a certain value (being threshold value), electric current is minimum, and is not luminous in forward voltage values.After voltage surpassed a certain value, forward current increases sharply with voltage, and was luminous.
4. luminous intensity IV: the luminous intensity of light-emittingdiode typically refers to the luminous intensity on normal (cylindrical luminous tube is meant its axis) direction.If when radiation intensity is (1/683) W/Sr on this direction, then luminous 1 candela (symbol is cd).Because the luminous intensity of general LED is little, so luminous intensity candle light (candela, mcd) office commonly used.
5.LED lighting angle :-90 °-+90 °.
6. spectral half width Δ λ: the spectral purity of its expression luminous tube.
Half-value angle θ 1/2 and visual angle: θ 1/2 be meant luminous intensity values be the axial strength value half direction and light-emitting axis to the angle of (normal direction).
