Abstract
Abstract A light system for providing uniform actinic radiation to fingernails while in a predetermined position, including a generally ellipsoidal housing having a circular horizontal cross-section and reflective inner surfaces to concentrate light, the surfaces being so shaped and so dimensioned as to concentrate, in the predetermined position, the light rays from an ultraviolet lamp in the housing, an opening in the housing to receive the hand of a user, and means for guiding the user's hand so as to position the fingernails of the hand in the predetermined position, the guiding means including a handle to be grasped by the user and means interconnecting the handle and housing and controlling the position of the handle as it is moved within the housing. An adjustable timer may be provided to control exposure times.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
139 words
A light source for curing gel on fingernails and providing uniform radiation levels thereto, said light source including a housing having lamp means therein for treating said gel, said lamp means emitting ultraviolet rays, support means for said housing, a closure member, said housing including an opening therein on the bottom of said housing to receive said closure member and to retain said closure member within said housing means for mounting said closure member for vertical movement within said housing and upwardly from said opening, and a handle secured to said closure member and positioned to be grasped by the user's hand and moved inwardly of said housing, wherein grasping said handle and moving it inwardly serves to bring the user's fingernails into said housing and to allow them to be exposed to said rays from said lamp means.
Claim 2
Dependent Claim
139 words
A light source for curing gel on fingernails and providing uniform radiation levels thereto, said light source including a housing having lamp means therein for treating said gel, said lamp means emitting ultraviolet rays, support means for said housing, a closure member, said housing including an opening therein on the bottom of said housing to receive said closure member and to retain said closure member within said housing means for mounting said closure member for vertical movement within said housing and upwardly from said opening, and a handle secured to said closure member and positioned to be grasped by the user's hand and moved inwardly of said housing, wherein grasping said handle and moving it inwardly serves to bring the user's fingernails into said housing and to allow them to be exposed to said rays from said lamp means.
Claim 3
Dependent Claim
68 words
A light source as set forth in claim 1 in which said lamp means, said handle, and said closure member are so dimensioned and so positioned relative to one another such that said lamp means is above and surrounding said fingernails when said handle is grasped and moved inwardly and upwardly wherein said fingernails are positioned to receive substantially uniform exposure to the rays of said lamp means.
Claim 4
Dependent Claim
16 words
A light source as set forth in claim 1 in which said housing is generally ellipsoidal.
Claim 5
Dependent Claim
47 words
A light source as set forth in claim 1 including a switch mounted within said housing and so positioned as to be actuated by contact with said closure member, wherein grasping said handle and moving it inwardly toward said housing will serve to operate said lamp means.
Claim 6
Dependent Claim
18 words
A light source as set forth in claim 1 including a timer operatively associated with said lamp means.
Claim 7
Dependent Claim
38 words
A light source as set forth in claim 1 including a timer for said lamp means, and said timer being operatively associated with said closure member, wherein predetermined movement of said closure member serves to actuate said timer.
Claim 8
Dependent Claim
25 words
A light source as set forth in claim 4 including a timer operatively associated with said switch, wherein actuation of said switch starts said timer.
Claim 9
Independent Claim
87 words
A system for positioning one's hand during exposure of the fingernails to actinic radiation such that said fingernails receive substantially uniform radiation, said systems including a light source, a housing therefor, said light source being positioned on the upper inner surface of said housing, a member associated with said housing to be grasped and moved by the hand, and means for guiding motion of said member upwardly and vertically within said housing wherein said fingernails are positioned approximately in the point of concentration of said light source.
Claim 10
Independent Claim
87 words
A system for positioning one's hand during exposure of the fingernails to actinic radiation such that said fingernails receive substantially uniform radiation, said systems including a light source, a housing therefor, said light source being positioned on the upper inner surface of said housing, a member associated with said housing to be grasped and moved by the hand, and means for guiding motion of said member upwardly and vertically within said housing wherein said fingernails are positioned approximately in the point of concentration of said light source.
Claim 11
Dependent Claim
22 words
A system as set forth in claim 8 in which said member is telescopingly secured to the inner surface of said housing.
Claim 12
Dependent Claim
33 words
A system as set forth in claim 8 in which said housing has reflective inner surfaces, and said surfaces are so shaped as to concentrate said light source upon said point of concentration.
Claim 13
Dependent Claim
17 words
A system as set forth in claim 10 in which said housing has a generally ellipsoidal shape.
Claim 14
Dependent Claim
15 words
A system as set forth in claim 8 including a timer for timing said exposure.
Claim 15
Dependent Claim
18 words
A system as set forth in claim 12 in which said timer is actuated by said guiding means.
Claim 16
Dependent Claim
141 words
A light system for providing actinic radiation to fingernails on a user's hand and for positioning said fingernails to receive said radiation, said system including a generally ellipsoidal housing having a circular horizontal cross-section, support means for said housing, a circular, ultraviolet lamp means positioned within said housing in a horizontal plane proximate to the upper surface thereof, said housing having reflective inner surfaces, said surfaces being so shaped and so dimensioned relative to the position of said lamp means as to concentrate the light rays from said lamp means in a predetermined location, an opening in said housing to receive said user's hand, and means for guiding the user's hand vertically upwardly within said housing so as to position the fingernails of the hand in said predetermined position, wherein said fingernails may receive substantially uniform exposure to said light rays.
Claim 17
Dependent Claim
141 words
A light system for providing actinic radiation to fingernails on a user's hand and for positioning said fingernails to receive said radiation, said system including a generally ellipsoidal housing having a circular horizontal cross-section, support means for said housing, a circular, ultraviolet lamp means positioned within said housing in a horizontal plane proximate to the upper surface thereof, said housing having reflective inner surfaces, said surfaces being so shaped and so dimensioned relative to the position of said lamp means as to concentrate the light rays from said lamp means in a predetermined location, an opening in said housing to receive said user's hand, and means for guiding the user's hand vertically upwardly within said housing so as to position the fingernails of the hand in said predetermined position, wherein said fingernails may receive substantially uniform exposure to said light rays.
