Abstract
Abstract A method for quickly, efficiently and accurately aiming a flood light at a preselected location which involves directing or redirecting the collimated radiative output of a low power laser source at a preselected location. The laser output may be aimed at a mirror on the flood light face and reflected directly back to the preselected location or the laser can be temporarily mounted to the flood light and the laser output directed parallel to the flood light beam axis at said preselected location.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
77 words
The method of aiming a flood light at a preselected location comprising the steps of: situating a laser at said preselected location; directing the collimated radiative output of said laser at a mirror surface on the face of a flood light; adjustably aiming said flood light to cause said laser output to reflect from said mirror surface back to said preselected location; and fixing said flood light in a position to remain aimed at said preselected location.
Claim 2
Independent Claim
77 words
The method of aiming a flood light at a preselected location comprising the steps of: situating a laser at said preselected location; directing the collimated radiative output of said laser at a mirror surface on the face of a flood light; adjustably aiming said flood light to cause said laser output to reflect from said mirror surface back to said preselected location; and fixing said flood light in a position to remain aimed at said preselected location.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said mirror surface is a gold mirror.
Claim 4
Dependent Claim
28 words
The method of claim 1 wherein a target is placed at said predetermined location whereby perception of impingement of said laser output at said predetermined locations is enhanced.
Claim 5
Dependent Claim
15 words
The method of claim 1 wherein said laser is a five milliwatt helium neon layer.
Claim 6
Independent Claim
69 words
A method for aiming a flood light at a preselected location comprising the steps of: placing a reflective mirror over the lens of said flood light; locating a laser at said preselected location; directing the collimated radiative output of said laser at said reflective mirror on said flood light lens; and adjusting the direction of said flood light to reflect the directed laser output back to said preselected location.
Claim 7
Independent Claim
69 words
A method for aiming a flood light at a preselected location comprising the steps of: placing a reflective mirror over the lens of said flood light; locating a laser at said preselected location; directing the collimated radiative output of said laser at said reflective mirror on said flood light lens; and adjusting the direction of said flood light to reflect the directed laser output back to said preselected location.
Claim 8
Dependent Claim
13 words
The method of claim 5 wherein said reflective mirror is a gold mirror.
Claim 9
Dependent Claim
28 words
The method of claim 5 wherein a target is placed at said preselected location thereby enhancing the perception of impingement of said laser output at said preselected location.
