Patent ID: 7712919

Claim:
A dental operation light, comprising an at least one light-emitting component ( 9 ) having a light-emitting surface and an at least one light-reflecting surface (Mn), wherein the light-emitting surface of the at least one light-emitting component ( 9 ) is so arranged in the operation light that all or substantially all of the light produced by the operation light consists of light reflected from the at least one light-reflecting surface (Mn), and for each light-emitting component ( 9 ) at least one light-reflecting surface (Mn) is provided so that, regarding each light emitting component ( 9 ), the dimensions of the light-emitting surface in relation to the size of the at least one light-reflecting surface (Mn) arranged for the light-emitting component ( 9 ) in question, the direction of the normal to the light-emitting surface in relation to the direction of the normal to the at least one light-reflecting surface (Mn) arranged for the light-emitting component ( 9 ) in question, and the distance of the light-emitting surface to the at least one reflecting surface (Mn) arranged for the light-emitting component ( 9 ) in question in relation to the distance of the light-reflecting surface (Mn) to a light pattern forming surface ( 11 ) have been so arranged that the dental operation light produces, on the light pattern forming surface ( 11 ), a light pattern of a given shape and size wherein the light intensity in the penumbral shadow area formed at the edges of the light pattern falls in a desired manner.
