摘要：

Light-emitting diode (LED), smaller and less expensive, requires less power than laser does, is more and more popular in studying photobiomodulation. Three new LED systems with different intensity have been designed in this paper. The three LED systems consist of a set of lens to expand the beam of light or/and to focus the rays of light, and an array of LEDs set in the sphere connected with Fresnel lens. The intensity of the three LED systems ranges from: 0.002 to 1.465 W/m(2) with the spot diameter 40 mm; 0.358 to 11.229 W/m(2) with the spot diameter 60 mm; 17.626 to 115.371 W/m(2) with the spot diameter 80 mm. Their experimental formulae for calculating intensity were obtained by SPSS.
