Oral Laser Device with Segmented LED Array and Resin Covers

The patent divides the single laser source into multiple laser diodes arranged in an array. Each laser diode emits light that is transmitted through a separate light guide to a specific target region in the oral cavity. This segmentation allows the treatment area to be expanded while each individual laser beam maintains its intensity, as the energy is distributed across multiple focused beams rather than one expanded beam.

The patent introduces light guides as intermediary elements between the laser diodes and the oral cavity. These light guides directly transmit the laser light from each diode to the target region without requiring reflection units. This eliminates energy loss associated with reflection while maintaining the ability to reach various treatment angles through the flexible arrangement of multiple light guides.

The patent segments the laser source into multiple laser diodes that emit at different wavelengths. This allows simultaneous irradiation of the oral cavity with multi-wavelength light, enabling deeper penetration into living tissue while maintaining a relatively simple device structure through the use of an array of standard laser diodes and corresponding light guides.

The patent divides the treatment path into multiple short segments, with each laser diode and its corresponding light guide forming an independent transmission channel. This segmentation ensures that each light path remains relatively short and direct, minimizing energy loss while collectively covering a broad treatment area through the coordinated action of multiple channels.
