Luminous intensity test device

摘要

A luminous intensity test device includes an optical frequency converter, a display, and a processor. The optical frequency converter selectively converts at least a portion of light emitted by a light source into a digital signal. The display displays a color selection interface. The processor processes the digital signal and obtains the luminous intensity. When a tester inputs a color parameter into the color selection interface via an input device, the optical frequency converter converts a kind of light to the digital signal and then the processor processes the digital signal to obtain a luminous intensity and display the luminous intensity on the display.

主权项

1. 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.
