<p>An irradiation device comprises at least one LED (11). The LED (11) can generate more than one narrow bandwidth centered at a wavelength as low-energy non-parallel concentrated light. The wavelength of the concentrated light is between 600 to 850nm, the energy density of the light is between 2 to 16J/cm2, and the divergence angle of the light is within 16 degree. An irradiation system using the irradiation device comprises a driver (12) to drive the LED (11) to generate the concentrated light, and a power supply (13) to provide power to the system.</p> |
