Abstract
Abstract A method of making an illuminating device such as a flood light or vehicle headlight in which a light source is mounted in a jig including a member for adjustably supporting a plurality of selected small reflectors. Reflectors are selected, mounted in said jig and each reflector is adjusted to direct light impinging on that reflector to a selected area to be illuminated. After having selected and adjusted each small reflector, a matrix is made from the reflecting surfaces mounted in the jig and this matrix is used in a known manner to form male and female dies for forming one or more reflecting devices having facets to reflect light in the same pattern as determined by the adjustment of the selected small reflectors in the jig. The invention also contemplates reflectors made by the novel method.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
A method of making a reflector for a flood light or the like comprising the steps of providing a jig, and providing a light source to shine light into said jig, providing a plurality of small reflectors having reflective surfaces of various configuration, adjustably mounting said small reflectors in said jig to receive light from said light source, adjusting said small reflectors in said jig to direct the light to the desired areas to be illuminated, removing said light source, pouring a molding material against the adjusted small reflective surfaces in said jig, forming male and female reflector forming dies from said molding material after it has aired and stamping metal reflectors having multiple reflective surfaces between said dies.
Claim 2
Independent Claim
119 words
A method of making a reflector for a flood light or the like comprising the steps of providing a jig, and providing a light source to shine light into said jig, providing a plurality of small reflectors having reflective surfaces of various configuration, adjustably mounting said small reflectors in said jig to receive light from said light source, adjusting said small reflectors in said jig to direct the light to the desired areas to be illuminated, removing said light source, pouring a molding material against the adjusted small reflective surfaces in said jig, forming male and female reflector forming dies from said molding material after it has aired and stamping metal reflectors having multiple reflective surfaces between said dies.
Claim 3
Dependent Claim
29 words
The method of claim 1 including the step of providing a first reflector to receive light from the light source and reflect it onto the plurality of small reflectors.
Claim 4
Dependent Claim
162 words
A jig for fashioning an illuminating device comprising a housing having a base and a supporting portion and an open area, a light source disposed in said housing substantially at an area where said base and said support portion meet, a baffle disposed in said housing at said area overlying said light source to exclude light from directly impinging on said support portion but allowing the light source to radiate upon said base, a reflector disposed upon said base in said housing having a contour which causes light from said source to be reflected from said base in parallel rays, a plurality of reflecting elements disposed in said housing on said supporting portion oriented to receive the parallel rays emanating from said reflector, each of said reflecting elements having means for adjusting the angle of orientation of said reflecting elements so that light impinging on said reflective elements may be focused as it travels outwardly from said housing through said open area.
Claim 5
Dependent Claim
162 words
A jig for fashioning an illuminating device comprising a housing having a base and a supporting portion and an open area, a light source disposed in said housing substantially at an area where said base and said support portion meet, a baffle disposed in said housing at said area overlying said light source to exclude light from directly impinging on said support portion but allowing the light source to radiate upon said base, a reflector disposed upon said base in said housing having a contour which causes light from said source to be reflected from said base in parallel rays, a plurality of reflecting elements disposed in said housing on said supporting portion oriented to receive the parallel rays emanating from said reflector, each of said reflecting elements having means for adjusting the angle of orientation of said reflecting elements so that light impinging on said reflective elements may be focused as it travels outwardly from said housing through said open area.
Claim 6
Dependent Claim
14 words
The jig of claim 3 further including a lens which overlies said open area.
Claim 7
Dependent Claim
30 words
The jig of claim 3 in which said means for adjusting the angle of orientation of said reflecting elements comprises wires which connect said reflecting elements to said supporting portion.
