L-HAST  
 
 
ddd  Usable test environment is temperature 120℃ and relative humidity 85%.
ddd  Number of channels in total : 40 channels
    Number of channels per LBU : 8 channels
    Number of LBU : 5 units
ddd  Constant current is supplied to each channel Range of constant current : 1mA - 500mA
      (More than 500mA is being planned)
ddd  It is possible to measure forward voltage(Vf) simultaneously with the light output.
ddd  The tendency of luminance degradation becomes clear within one week.
ddd  The measurement data can be converted into a CSV format.
ddd  The sampling interval is 1 minute.

 

 

   
 
 
  The data converted into a CSV format is transmitted to the personal computer from the measuring
unit via USB interface. The measurement data is saved, processed and graphed out. The sampling
interval is 1 minute and the displayed data is output every 1 minute.
Example of graph display : Luminance degradation graph of the LED, Changes in forward voltage (Vf)
 
   
 
■ LED Benchmark Test System (LBS); consisting of the following units
Photo Detection Unit (PDU)
Detector of the LED light output.
Capable to mount up to 8 LEDs per one LBU and

detect each LED light output.
   
LED Benchmark Test Unit (LBU)
This unit supplies constant current, measures the
light output and the forward voltage, and transmits
the measurement data to the PC via USB interface.
(8 channels per LBU)
■HAST Equipment Model PC-R8 series
HAST equipment produces the accelerated test environment of 120℃
and 85%RH.
Up to 5 LED benchmark test systems (LBS) can be installed in the HAST
equipment model PC-R8.


■Interface cable
Connection cable between PDU and LBU.

■Control PC
The PC obtains the data from the LBU via USB interface
The program control as well as startup or stop of the system can be performed with this PC.
