ELECTRICAL DEVICE WITH LIGHT CONDUIT SYSTEM
An electrical device includes a screen with an aperture formed therein. The device includes a light source, a light sensor and a light conduit. The light conduit is operatively positioned between the aperture on one side and the light source and light sensor on the other. When the light source is activated, some of the light energy emitted therefrom is received in the light conduit. This light energy can travel through the light conduit to the aperture, through which the light energy can exit the device, thereby providing notice to a user of some condition. Light energy received in the aperture from outside the device can enter the light conduit and pass therethrough to the light sensor. The brightness of the screen can be adjusted based on the amount of light energy received by the light sensor.
