More Information
Summary:A light irradiation apparatus for a dental photo polymerization composite resin of multi-purpose type which can efficiently and completely polymerize and cure the dental photo polymerization composite resin using a combination of the camphor quinone and the tertiary amine as the photo polymerization catalyst, and can also polymerize and cure the dental photo polymerization composite resin using the acylphosphine oxide as the newly developed photo polymerization initiator, with a structure such that there are arranged a blue ray radiation LED 5 having luminous wavelengths peaked at a wavelength of 450 nm or more but not more than 490 nm, and a near ultraviolet rays and/or violet rays radiation LED 6 having luminous wavelengths peaked at a wavelength of 370 nm or more but less than 410 nm, and there is provided a circuit changing switch 7 at least for simultaneously turning on these two kinds of LEDs 5, 6 and for turning on only the near ultraviolet rays and/or violet rays radiation LED 6.
