LED chip technology issues

First, the optical performance testing.The main parameters include voltage, light intensity, wavelength range, half width, color temperature, color rendering index, etc. These data can be tested with the integrating sphere.

Second, the reliability test.The main parameters include the light failure, leakage, anti-pressure, anti-static, IV curves, etc., these data are generally tested by aging

Third,White LED normally obtained in two ways:

First, through with light, the red, green and blue chip package to obtain matching white LED.

Second, through phosphor conversion blue LED, to obtain white light LED.
