چکیده انگلیسی
Red and yellow light emitting diodes (LEDs) are currently utilized as lighting sources during LED phototherapy. These LEDs were arranged on a disk with an external diameter of 70Â mm with different arrays - radial, rhombus, square radial, and square rhombus arrays. The radial and square radial arrays had better irradiance efficiency than rhombus and square rhombus arrays by optical simulation. Additionally, the radial array had 76 sets of LEDs, but the square radial array had 100 sets. Thus, a mockup sample of radial array phototherapy was constructed for performance tests. The mixture efficiency of the radial array was observed at distances of 1-100Â mm and lighting was well mixed when distance exceeded 50Â mm by optical simulation. Irradiance variation with angle was approximated by experiment and theory at a treatment distance of 50Â mm and 100Â mm using the phototherapy mockup. The radial array was one good choice for LED phototherapy.
