Optical Efficiency η op 39.31 lm/W Thermal resistance [5] Rth JA 360 ℃ / W Rth JS 180 ℃ / W Temperature coefficient of V F -10℃ ≤ T ≤ 100 ℃ TC v -2.73 mV/℃ Temperature coefficient of X -10℃ ≤ T ≤ 100 ℃ TC x -0.11 10-3/℃ Temperature coefficient of Y -10℃ ≤ T ≤ 100 ℃ TC y -0.10 10-3/℃ Luminous Intensity Phi V / IV ∂Ω 3.0 3.1 lm/cd (1) Tolerance : VF :±0.1V, IV :±10%, x,y :±0.005 (2) The luminous intensity IV was measured at the peak of the spatial pattern which may not be aligned with the mechanical axis of the LED package. (3) Correlated Color is derived from the CIE 1931 Chromaticity diagram. (4) Θ 1/2 is the off-axis where the luminous intensity is 1/2 of the peak intensity (5) Thermal resistance = Rth JA : Junction/ambient , Rth JS : Junction/solder point Pad design for improved heat dissipation : Cu-area > Cu 16mm2 per pad, FR4, t=1.6mm (6) Not designed for reverse operation Notes : |
