Light sensor having partially opaque optic
First Claim
1. A light sensor package comprising:
- an enclosure having a window for receiving light, the enclosure admitting at least a power connection pad, a ground connection pad, and an input/output pad;
an exposed light transducer disposed within the enclosure, the exposed light transducer operative to accumulate charge in proportion to light received through the window incident on the exposed light transducer over an integration period;
a light-to-pulse circuit in communication with the exposed light transducer, the light-to-pulse circuit operative to output a pulse on the output pin, the pulse width based on the charge accumulated by the exposed light transducer over the integration period; and
a nonvolatile memory within the enclosure for storing data from which calibration data may be obtained for the light sensor package.

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.
