Patent ID: 7955366

Claim:
A biostimulative illumination system for treating patient tissues, comprising: at least one group of light emitting diode apparatus, comprising at least one light emitting diode which can generate at least one narrow-pulse focused wave band suitable to be used as low-power and non-parallel focused light beam for biostimulative illumination, wherein the wave length of the focused light beam is from 600 nm to 850 nm, the energy density of the focused light beam is greater than 2 Joule/cm 2 and lower than 16 Joule/cm 2 and the divergence angle of the focused light beams is smaller than 16°; a driver for driving the light emitting diode to generate a focused light beam; and a power source for supplying power for the biostimulative illumination apparatus, wherein the driver comprises: a voltage control circuit for receiving modulated pulses from a CPU and then generating voltages to the light emitting diode apparatus for generating focused light beams with different energy; and a CPU for computing the frequency of the focused light beam and further for providing a corresponding control signal to the voltage control circuit.
