Title:
ILLUMINATED ELECTRIC TOOTHBRUSHES
Document Type and Number:
WIPO Patent Application WO2005023131
Kind Code:
A3
Abstract:
An illuminated electric toothbrush comprising a light emitting diode emitting light having a flux density of at least about 30 mW/cm<2>. An illuminated electric toothbrush having this level of flux density can result in an oral care benefit such as whitening. When this toothbrush is used within the oral cavity the heat generated by the toothbrush remains low enough that the surface temperature of the teeth remains below about 43 °C. The flux density of at least about 30 MW/CM<2> can be achieved by overpowering the light emitting diode, by using a light emitting diode having at least about two dices, and by providing a pulsed or non-continuous current to the LED which results in a pulsing or non-continuous light.
