LED array electrical characteristics
Note
(1) LED light bar input voltage and current are measured by utilizing a true RMS multimeter as shown
below:
(2) PBL = IPIN × VPIN × ( 8 ) input pins , LED light bar circuit is ( 9 )Series, ( 8 )Parallel.
(3) The lifetime of LED is defined as the time when LED packages continue to operate under the
conditions at Ta = 25 ±2 ℃ and I= (25)mA (per chip) until the brightness becomes ≦ 50% of its
original value.
Note 1 :The specified current is input LED chip 100% duty current.
Note 2 : The value showed in the table is one light bar’s operation voltage.
Note 3 : Definition of life time : brightness becomes 50% of its original value. The minimum life time of LED unit is on
the condition of IRLED =60mA and 25±2℃(Room temperature).
Note 4: Each LED light bar consists of 64 pcs LED package ( 4 strings x 16 pcs / string ).
