Patent ID: 8668346

Claim:
A simulated sunlight generating device for generating a simulated sunlight, comprising: a plurality of driving units for generating a plurality of driving currents; a plurality of light-emitting units connected to the driving units for emitting light of corresponding wavelength and illumination intensity based on a strength of the plurality of driving currents, the strength of the plurality of driving currents being adjustable to equalize the illumination intensity of the emitting light; and a plurality of adjusting units disposed at a light-emitting route of the light-emitting units, changing light-emitting directions of the light-emitting units, and enabling light rays emitted from the light-emitting units to propagate along a same light route, the light rays being simultaneously added up, combined and dynamically analyzed by the plurality of adjusting units to form the simulated sunlight, the simulated sunlight propagating in the light-emitting directions with high efficiency and high directivity.
