1. A cap for a light sensor, the cap comprising:
a top wall;
a sidewall extending perpendicularly from the top wall and extending therearound;
a partition sidewall extending from one portion of the sidewall to another portion of the sidewall to thereby define first and second cavities;
wherein the first cavity includes a central through-opening that extends through the top wall;
a lens installed within the central through-opening, with the lens having a cavity defined in its exterior sidewall to completely encircle a lower portion of the exterior sidewall;
the central through-opening being defined by an interior sidewall extending through the top wall, with a ridge extending outwardly from the interior sidewall, the interior sidewall and ridge being integrally formed as a monolithic unit;
at least one relief blind-opening that extends into but not through the top wall, wherein the at least one relief blind-opening intersects the central through-opening so as to be in fluid communication therewith; and
wherein the ridge extends completely around the interior sidewall so that the lens is mechanically anchored in place by the ridge interfacing with the entirety of the cavity defined in the exterior sidewall of the lens, while an upper portion of the exterior sidewall of the lens extends into the at least one relief blind-opening and in physical contact with portions of the top wall defining the at least one relief blind-opening.
