Curing light of Dental composite resins using high brightness LEDs.

摘要

1. Lamp photopolymerization of dental composite resins using high brightness LEDS consisting of a lamp installed in a suitable base may be the surface of a table or a box shape a spheroidal chamber for curing dental resins by light produce LEDs of the core, to restore missing teeth or damaged in dental laboratories, characterized by having a lamp of high brightness LEDs with two green LEDs and blue LEDs called Nucleus (N) on the inside of a reflector (R) stainless steel bowl shaped upside down and combined with another reflector (r) bowl-shaped face up, so the polymerization chamber that has high intensity light of 465 to 520 nm wavelength to polymerize the composite resins used in dental laboratories. The polymerization chamber is spheroidal has a mechanism for opening and closing characterized by having a hinge (B) riveted to the back of the upper reflector (R) which acts as a cover and the other hinge part is fixed in the table or box which is installed with screws. Two handles (T) in front of the upper reflector near the edge bolted on each side allow the grip to open and close the chamber. The bottom (r) of the camera is a faceup bowl 14 cm diameter is embedded in a circular hole of the table or box. It is of polished stainless steel and will resting on the flap (s) of its outer edge. Inside it a hemispherical part (h) also stainless steel having screwed a transparent acrylic sheet (m) 4 mm thick which supports the object to be processed and allows the passage of light reflected upward to rests impinging on the object it acts parabolic reflector returning the light reflection. The outer surface of the upper reflector or cover and a hole (a) 1 cm out the cord (C) of the lamp current by connecting to an external power source which supplies 13 volts DC. The source carries a timer to regulate activation times 0.5 to 7 minutes. To allow viewing inside the correct placement of the object the upper reflector or cover has practiced a window (E) of 50 mm light at its front part by a frame is supplied with integral (dark green) color filter which prevents glare to see inside. 2. Curing of dental composite resins using high brightness LEDs characterized by having an essential element: The Core lamp (N) characterized by having eight high power LEDs, blue and 2 green 6 attached with thermally conductive adhesive in two plates (P) aluminum length 13 mm long, 4 mm thick and 40 wide at three blue and green plate with two angles of 45 degrees to direct the light to direct and laterally one object. The plates are screwed and glued onto a disc (D) 110 mm in diameter and 15 mm thick. Two screws (T) traversing the disc nut and washer shaped piece or ring (A) with two perforations. These screws (T) pass through the ring adaptation, fastened with two nuts, they are emerging and allow the core holding of the lamp to the reflector-cover (R) higher by two nuts. This core acts as a support for the strips with LEDs and efficiently dissipates heat produced by photoemission (the power consumed by the LED array is 21 watts). It is aluminum being a good conductor of heat. LEDs emit blue light used 465 and green 520 nm wavelength to cover the spectrum of polymerization of the usual materials. 3. The lamp to polymerize composite dental resins by bright LEDs in a portable assembly characterized by arranging an upper reflector (R) on the lid of a briefcase appropriate minimum dimensions and a lower reflector (R) in a bore of said lid, recessed, with accessory elements (hemispherical stainless steel base and transparent methacrylate h, m) and connecting the power supply-timer lamp cable (C) to operate the apparatus. This assembly is a novelty for making portable apparatus for teaching purposes and presentations thing with existing appliances with halogen lamps could not be done easily by the characteristics of volume, weight of the device and fragility of crystal producing elements light such devices. The lamp polymerization of dental resins mounted case allows removal of the top reflector (R) of the cover opening a (P) securing the hinge to remove it, extract the core (N) and reassembles at the same site but with the lower reflector (r) into the top and secure the assembly with screws (T) protruding from the core of the lamp and nuts. The bottom reflector, which is the smaller of the two, has two circular holes of 5 mm diameter corresponding to the reflector-cover being equidistant and of the same diameter. Placing the lower inside upper with holes of 5 mm from both reflectors in correspondence and replacing the core of the lamp in place the assembly is held by two screws (t) projecting from the core and corresponding nuts so that allows meter assembly parts of the lamp in the case including the power supply and making the device portable. 4. The dental curing light composites with high brightness LEDs characterized by having a latch (P) which ensures security in his (left in the figure) closed position the bolt assembly to prevent accidental dismantling of the upper reflector cap makes the polymerization chamber and having two open and closed positions. It is mounted on the part of the bolt which is fixed on the mounting base, with a screw (t) with nut passing through the center hole of the hinge that is fixed to the mounting base by turning shaft to allow movement.
