摘要：
A portable self-contained tooth-whitening device includes a compact housing structured and configured to be held in a fixed position adjacent to a human jaw during use at least a first array of LEDs disposed in a first plane at a front side of the housing and arranged to deliver blue visible light or near-visible UV light of at least a threshold intensity to substantially all anterior surfaces of anterior maxillary teeth or anterior mandibular teeth of the human jaw, wherein the first array of LEDs forms at least two intersecting arcs, each of which is disposed in the first plane and has its own focal point located outside the device and at least one battery cell powering the array of LEDs.
