The present invention relates to a curing light with a heat dissipation structure, more specifically to a curing light that is capable of curing a gum inflammation treatment material, while improving heat dissipation performance thereof.
Generally, implants are replacement human tissues when original human tissues are missing, and further, dental implants are artificial tooth roots used to support a restoration for missing teeth. To replace a missing tooth root, in specific, dental implant surgery is carried out to place a fixture made of a material having no rejection reaction to the human body in the alveolar bone and to then fix an artificial tooth to the fixture, so that the function of the tooth can be restored.
A general dental prosthesis or denture causes neighboring teeth and bones to be damaged as time passes, but a dental implant causes no damage on the neighboring teeth and bones and does not have any secondary decay, so that the dental implant is used stably. However, inflammation may occur on the gum around the dental implant.
To apply an anti-inflammation material onto an inflammatory lesion or gum around the implant, the anti-inflammation material is conjugated with collagen gel so that it physically sticks to the inflammatory lesion or gum. Through the efficacy of the anti-inflammation material sticking to the inflammatory lesion or gum, the inflammation can be consistently inhibited.
In this case, a curing light for a local lesion such as gums has a physical limitation because the lesion as a light-cured subject is narrow and small, and accordingly, the curing light has the shape of a generally long narrow rod.
Therefore, the curing light requires a structure capable of performing effective heat dissipation because of its structural limitation.
Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the related art, and it is an object of the present invention to provide a curing light with a heat dissipation structure that is capable of effectively dissipating the heat emitted from a light source through the heat dissipation structure in which heat sinks are coupled to each other to accommodate the light source therein.
It is another object of the present invention to provide a curing light with a heat dissipation structure that is capable of allowing one side heat sink to be exposed to the outside, thereby having advantages such as conveniences of use and easy heat dissipation.

According to the present invention, desirably, the curing light may further include: a head for accommodating an optical fiber adapted to irradiate the light emitted from the light source onto the outside; and a head fixing part for fixing the head thereto and coupled to the second heat sink in such a way as to dissipate the heat received from the second heat sink to the outside.
According to the present invention, desirably, the second heat sink may have a fastening portion formed on one side of the light transmission hole in such a way as to be fastened to a coupling portion formed on the head fixing part.
According to the present invention, desirably, the first heat sink and the second heat sink may be made by means of die casting and post-processing using aluminum.
