Title:
導光部を備えた歯照明装置
Document Type and Number:
Japanese Patent JP7183162
Kind Code:
B2
Abstract:
The invention relates to an oral care device for teeth whitening or other purpose. The device is designed to provide a uniform light intensity distribution at the teeth. This is achieved by use of a light guide which at some surface parts is separated from surrounding parts of the mouthpiece of the oral care device by air-filled separation portions. The light guide mixes the injected light to improve the uniformity of the light intensity. In 5 order to couple light out from the light guide, the mouthpiece comprises an out-coupling structure located opposite to the buccal side of the teeth. The out-coupling structure may be shaped, e.g. by changing the area or density of parts of the out-coupling structure depending on the distance to a location of the light guide where light is injected.
