Abstract

See full text

A wafer-grade LED detection device and a wafer-grade LED detection method are provided. The wafer-grade LED detection device includes a light-generating module for providing a first light beam that passes through an LED wafer to be converted into a second light beam, a light-filtering module adjacent to the LED wafer for receiving the second light beam that passes through the light-filtering module to be converted into a third light beam, and a light-detecting module adjacent to the light-filtering module for receiving and detecting the third light beam. A wavelength range of the second light beam is restricted by the light-filtering module, so that a wavelength range of the third light beam is smaller than the wavelength range of the second light beam. When the third light beam is received by the light-detecting module, the light-detecting module can detect the third light beam for obtaining relevant information.
