Note (1) LED current is measured by utilizing a high frequency current meter as shown below:
Note (2) The lifetime of LED is defined as the time when it continues to operate under the conditions at
Ta = 25 ±2 and I_LED = 20mA_DC(LED forward current) until the brightness becomes 50% of its
original value.
Note (3) Please note that LED life will be shorter than the average life described in the specification if
operate in higher ambient temperature.
