Ultraviolet light emitting diode lamp for color perception research

摘要

Color inuences human decision making process,affects mood. It is important to investigate human colorjudgment of objects under different illumination. By controlling of a red (R), green (G), Blue (B) and Amber (A)colored lamp a MagnetoEncephaloGraphy (MEG) brain scanner was tested for its performance. We developeda software to generate all the colors in the visual spectrum, predefined white light combinations and saturationof an illuminated objects by using RGBA colors. The lamp was controled from outside of the shielded MEGroom while the LED lamp was located inside of electromagnetically shielded room. The USB was used as forLED-lamp control. To check the feasibility of using LED lamp with MEG brain scanner and showed feasiblityto use the LED-lamp, color control software and MEG scanner together for human and color related research.
