CHL-5LED Phosphor Relative Brightness Tester
CHL-5LED Phosphor Relative Brightness Tester is for testing phosphor relative
brightness and forward voltage of Excitation LED light source. It has equipped with
RS232 interface which can be communicate with the PC.


Forward voltage test range: 0.01~20.00V

Relative Brightness test range: 0.1%~999.9%

Test Accuracy: 0.5

Working power:
Supply voltage: AC 220V±10%
Power frequency: 50Hz/60Hz

Power dissipation: About 20VA

Working environment:
Allowed working environmental temperature: 0℃~40℃
Best temperature for normal measurement: 25℃±5℃

Size and weight:
External size: 220mm×148mm×390mm (width×height×depth)
Weight: About 3kg
Working Principle:

Forward voltage test: To provide specific forward working current for the tested
LED, and to detect the voltage generated between the two poles.

Relative Brightness test: The reference phosphor is lightened and excited by the
excitation apparatus, and then to receive optical signals by the V (λ) detector
and converts it into photocurrent, then the photocurrent converts into a voltage
signal and to be amplified, and then converts to digital by the modulus, and
then read by the microprocessor. Then the user-defined reference phosphor can
be got by the result of data read by microprocessor multiplied by the calibration
factor, and then put into the measured phosphor. The value read by the
instrument divide the reference phosphor data is the relative Brightness value.
