    Abstract: A rearview assembly for a vehicle is provided that includes: a housing configured for mounting to the vehicle; a rearview element disposed in the housing that displays images of a scene exterior of the vehicle; a light sensor assembly disposed in the housing; and a controller for receiving the electrical signal of the light sensor and for adjusting a brightness of the images displayed by the rearview element. The light sensor includes a light sensor for outputting an electrical signal representing intensity of light impinging upon a light-receiving surface of the light sensor, and a secondary optical element configured to receive light, wherein the light passes through the secondary optical element to the light sensor, the secondary optical element including a tint material that is substantially color neutral for attenuating light passing therethrough.

    Abstract: A light sensor is provided that includes an exposed light transducer for accumulating charge in proportion to light incident thereon over an integration period; and a light-to-pulse circuit in communication with the exposed light transducer, the light-to-pulse circuit operative to output a pulse having a pulse width based on the charge accumulated by the exposed light transducer. The light-to-pulse circuit may include a one shot logic circuit that contributes to generation of the pulse. The light sensor may include an input/output pad, a capacitor provided at the input/output pad for blocking static electricity, an input low pass filter provided at the input/output pad for blocking electromagnetic interference, and/or a bandgap voltage reference circuit connected to a power source having a supply voltage level in a range of about 3.3V to about 5.0V, and for generating a set of stable reference voltages throughout the supply voltage level range.
