2. Description of the Related Art Recently, a photopolymerizable resin which is polymerized by visible light has rapidly spread as a dental material for dental preservation and restoration. The photopolymerizable resin is a monomer in which a photosensitizer is blended, and the photosensitizer absorbs light and decomposes when irradiated with light, which initiates a polymerization reaction of the monomer. Such a photopolymerizable resin has an advantage that the polymerization reaction speed and the curing depth can be changed by the irradiation intensity of light. As dental materials, for example, α-diketones such as camphorquinone (CQ) are used as photosensitizers, and polyfunctional methacrylates such as methyl methacrylate are used as monomers. Camphorquinone absorbs light having a wavelength of 410 to 500 nm, but has a sharp absorption characteristic particularly for light having a wavelength of 430 to 480 nm.

A halogen lamp is generally used as a light source for curing such a resin. Since the output light of the halogen lamp contains light of various wavelengths, camphorquinone is well absorbed 410-410.
Light having a wavelength close to 500 nm is selected by an optical filter and is applied to the photopolymerizable resin. FIG. 4 shows a spectrum of light emitted from a conventional light source device and an absorption wavelength band of camphorquinone. Since the spectral spectra A to D of the conventional light source device composed of the combination of the halogen lamp and the optical filter are shifted to the longer wavelength side than the absorption wavelength band of camphorquinone, this light source is effective for curing camphorquinone. You can see that it is not working.

In particular, in this embodiment, most of the emitted light wavelength is 430 to 480 nm in the absorption wavelength band of camphorquinone.
The LED can be used to cure the resin with a minimum of light intensity. In the past, in order to cure a resin with a halogen light source, the intensity of the light source as a whole was increased to increase the intensity of light in the absorption wavelength band of camphorquinone, but at the same time, it was not necessary to cure the resin. The intensity of the light in the band is also increased, and the heat generated by the emitted light including such unnecessary light causes the haze of the concave mirror, but the present invention can solve this problem.

The photopolymerizable resin curing light source device of the present invention employs a plurality of LEDs as its light emitting source and emits light having a wavelength of 430 to 340 which is the absorption wavelength band of camphorquinone.
Since we chose the wavelength range of 480 nm, as a whole,
The photopolymerizable resin can be sufficiently polymerized with light having a smaller intensity than before. As a result, the power supply can be downsized. Further, since the sufficient intensity of light can be obtained, it is not necessary to bring the irradiation port very close to the affected area, and by placing a lens on the irradiation port of the light irradiation head and collimating the emitted light, the irradiation port can be further extended to the affected area. It is possible to separate the irradiation port from dirt and damage of the irradiation port is reduced. Further, since no heat is generated, it is safe and does not require a cooling fan, and the haze of the concave mirror which is the condensing optical system means of the third embodiment is reduced.
