Abstract
Abstract A mirror, preferably hand held, has a light source disposed behind the mirror and an integral source of electric current. The light source is located relative to a light reflective surface to direct light through an annular lens surrounding the mirror so that the light shines onto the face of the user to provide sufficient illumination to permit use independent of other light. The light produced is shadowless and characterized by softness. The systems employ reflective and refractive optics to converge and distribute light uniformly over the field of illumination.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
141 words
A mirror with optical light source comprising a hollow frame, a planar mirror closing off the center of said frame, an electric light bulb positioned within said frame immediately behind said mirror, first means establishing a light-transmitting medium from said bulb radially outwardly parallel to and in close proximity to the back of said mirror, second means establishing a lightfocusing surface at the outer perimeter of said first means beyond the margin of said mirror, said second means shaped to focus light from said bulb at a point disposed in front of the center of said mirror and spaced from said mirror to afford illumination of the face while looking into the mirror, said first means being circular and said second means being annular, whereby light is reflected from said bulb in an annular beam around the perimeter of said mirror.
Claim 2
Dependent Claim

A mirror with optical light source comprising a hollow frame, a planar mirror closing off the center of said frame, an electric light bulb positioned within said frame immediately behind said mirror, first means establishing a light-transmitting medium from said bulb radially outwardly parallel to and in close proximity to the back of said mirror, second means establishing a lightfocusing surface at the outer perimeter of said first means beyond the margin of said mirror, said second means shaped to focus light from said bulb at a point disposed in front of the center of said mirror and spaced from said mirror to afford illumination of the face while looking into the mirror, said first means being circular and said second means being annular, whereby light is reflected from said bulb in an annular beam around the perimeter of said mirror.
Claim 3
Dependent Claim
20 words
A source according to claim 1, which further comprises a battery and a switch wired in series with said bulb.
Claim 4
Dependent Claim
37 words
A source according to claim 2, installed in a woman''s compact having hinged cosmetic receptacle means and a lid in which said source is installed, said switch operable to energize said bulb when said lid is opened.
Claim 5
Dependent Claim
55 words
A source according to claim 1, in which said frame has a light reflective flat back parallel to the back of said mirror and a curved perimeter, said first means established by the reflective back of said mirror and of said back of said frame, said second means comprising the curved perimeter of said frame.
Claim 6
Dependent Claim
29 words
A source according to claim 1, in which said first means comprises an annular transparent plastic disk, said second means comprising the beveled outer back corner of said disk.
Claim 7
Dependent Claim
27 words
A source according to claim 5, in which the front of said disk outside the margin of said mirror comprises an annular lens of curved cross section.
Claim 8
Dependent Claim
65 words
A source according to claim 6, in which the curvature of said cross section is expressed: when y is the distance from the lens to the point of focus, x the distance from the center of said bulb to the middle of said beveled outer back corner, and a is the distance from the center of said bulb to the inner edge of said lens.
Claim 9
Dependent Claim
27 words
A source according to claim 5, in which said bulb is installed in the center opening of said disk, said opening only slightly larger than said bulb.
Claim 10
Dependent Claim
51 words
A source according to claim 5, in which said frame is formed complementary to the back of said disk and is further formed with a first pocket for said bulb and a second pocket for a battery and which further comprises a battery for said bulb installed in said second pocket.
