LED electrical testing and product use-EEWORLD

Collect

When testing VF, brightness, and wavelength, the current must be set to 20mA. When testing VR, IR must be set to 10uA. When testing IR, VR must be set to 5V. When testing and using LEDs, the same current must be provided to each LED, that is, a constant current source must be used for testing, in order to ensure the consistency of the brightness and other characteristics of the test.

LED is used in an ambient temperature between -30 ℃ ~ +60 ℃;

When using products with good spectrophotometry and color separation, do not mix products with different grade box numbers (marked on each package label) on the same product to avoid color and brightness differences. If you really need to mix grade box numbers, adjacent grade box numbers can be used together, but try to avoid this.

Light Bar LED Tester Circuit

The circuit is powered by a 4.5 volt battery and compared to a battery under test with an internal reference, which is set by R1, R2 and P1. For best results, the battery (DUT) should be loaded with a suitable resistor. The LM3914A LED bargraph is used here as a voltmeter to detect the battery. Bargraph LED Tester Cir
