摘要：
A short wavelength visible light-emitting toothbrush with an electronic interlock control device preventing operation when the toothbrush is removed from the users mouth. The electronic interlock control over operation is necessary to prevent accidental eye exposure to the high intensity light source with a wavelength in the range of 400 nm to 500 nm. The light-emitting toothbrush activates upon entering the users mouth but deactivates immediately when removed, thus protecting the users eyes from direct exposure to the high power light source contained in the brush head.
