Patent attributes
A light emitting toothbrush is provided that includes three light emitting diodes, each having a different primary color. A battery is provided as a power source, and a control circuit is used to control the diodes. The control circuit is configured to sequentially or simultaneously power some or all of the diodes, and it can be configured to vary the power to each diode, thereby providing an almost infinite spectrum of colors of light. A switch is actuated when the brush head contacts an operator's teeth, thereby activating the diodes. A package is provided that allows a potential purchaser to apply a force to the brush head and activate the lights while the toothbrush is still in the package. The control circuit can be configured to control the diodes to provide signals to the operator and/or provide aesthetically pleasing light.
