Patent ID: 8902415

Claim:
A luminous intensity test device, comprising: an optical frequency converter receiving light emitted by a light source and selectively converting at least a portion of the light into a digital signal, wherein the optical frequency converter comprises a photoelectric converter to convert the light into an analog signal, the photoelectric converter comprises a plurality of photodiodes which are divided into a plurality of kinds and two light-wave selection pins, each of the two light-wave selection pins receives a logic high signal or a logic low signal to select one kind of photodiodes to convert the light into the analog signal; a color selection interface displaying an interface to receive a color parameter; a processor receiving the color parameter via the color selection interface, controlling the optical frequency converter to convert the light into the digital signal based on the color parameter, processing the digital signal output from the optical frequency converter and obtaining a luminous intensity; and a display displaying the color selection interface and the obtained luminous intensity.
