SHORT WAVELENGTH VISIBLE LIGHT-EMITTING TOOTHBRUSH WITH AN ELECTRONIC SIGNAL INTERLOCK CONTROL

A toothbrush having one or more light sources with an electronic interlock control device preventing operation of the light source when the toothbrush is removed from the user's mouth. The electronicinterlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of about 400nm to about 1000nm. The light-emitting toothbrush activates upon entering the user's mouth but deactivates immediately when removed, thus protecting the user's eyes from direct exposure to the high power light source contained in the brush head. 种具有或多个光源的牙刷，其具有电子互锁控制装置，当所述牙刷从使用者的口腔移除时防止所述光源的操作。电子互锁控制操作是必需的以防止眼睛意外地曝露于具有约400nm到约1000nm范围内的波长的高强度光源。所述发光的牙刷在进入使用者的口腔后激活，但在移除时立即解除激活，因此保护使用者的眼睛使其不会直接曝露于刷头中所含有的高功率光源。
