Spot light fixture with beam adjustment

A spot light fixture with beam adjustment, comprising:

• a hollow base having an inner wall and a insert portion, the insert portion having a plurality of annular grooves formed therein;
• a hollow shroud having an inside wall with a first inner diameter and a ridge formed therein near a distal end, the ridge defining a second inner diameter that is smaller that the first inner diameter, wherein the first inner diameter is adapted to mate with the insert portion of the base to form a housing;
• a window disposed within the distal end of the shroud;
• a compression spring disposed within the base, the compression spring having a first end and a second end, the first end being disposed adjacent the inner wall of the base;
• a reflector assembly disposed at the second end of the compression spring, wherein the compression spring generates a bias to push the reflector assembly away from the inner wall of the base and toward the window;
• at least one optical element having a first outer diameter adapted to fit within the first inner diameter and larger than the second inner diameter for removable insertion into the shroud, wherein the at least one optical element modifies a beam emitted from the reflector assembly;
• at least one recessor ring having a second outer diameter adapted to fit within the first inner diameter and larger than the second inner diameter for removable insertion into the shroud, the recessor ring having an inner surface coated with a non-reflective material and a plurality of annular ribs formed thereon for reducing reflection of light from the inner surface, and a width adapted to force the reflector assembly away from the window to reduce glare from light from the reflector assembly;
• a retainer spring for retaining the at least one optical element and the at least one recessor ring within the shroud;
• at least one first O-ring having a first gauge disposed in one of the annular grooves in the insert portion of the base, wherein the first O-ring generates friction with the inside wall of the shroud;
• and
• a second O-ring having a second gauge smaller than the first gauge disposed in another of the annular grooves, wherein the second O-ring is disposed to abut an inside rim of the shroud when the housing is assembled to create a watertight seal between the shroud and the base.

A method for adjusting a beam produced by a spot light fixture comprising a housing enclosing a reflector assembly, the method comprising the steps of:

• opening the housing by separating a base from a shroud, wherein the base has an insert portion that mates with an inner diameter of the shroud and the shroud has a window disposed within a distal end;
• releasing compression of a spring disposed within the base for generating a bias for pushing the reflector assembly toward the shroud;
• removing a retaining spring disposed within the interior of the shroud;
• inserting within the interior of the shroud at least one insert having a first outer diameter adapted to fit within the inner diameter of the shroud, the at least one insert comprising at least one of an optical element and a recessor, the recessor having a plurality of annular ribs formed on an inner surface for reducing reflection of light from the inner surface and a width adapted to force the reflector assembly away from the window to reduce glare from light from the reflector assembly;
• replacing the retaining spring to hold the at least one insert within the shroud;
• aligning the shroud with the base so that the reflector assembly is within the shroud;
• and
• moving the shroud axially relative to the base so that the retaining spring presses against the reflector assembly and compresses the spring and moves the reflector assembly away from the window.
