USE OF INTEGRATING SPHERE TECHNOLOGY TO PROVIDE UNIFORM, HIGH-INTENSITY LIGHT, AND WAVELENGTH MIXING FROM LIGHT EMITTING DIODES
First Claim
1. A method for projecting light from a light fixture onto an object spaced from said light fixture, the light fixture having an integrating sphere, at least one light source, and at least one exit aperture, said method comprising:
- activating the at least one light source to emit light through the exit aperture onto the object spaced from said light fixture;
manipulating the at least one light source between a first configuration and a second configuration, wherein the at least one light source emits a first spectrum of light when the light source is in the first configuration and a second spectrum of light when the light source is in the second configuration.

Abstract
An illumination device including an integrating sphere and at least one light source. The integrating sphere is hollow and houses the at least one light source in it. The light source can be manipulated between a first configuration and a second configuration. The illumination device emits a first spectrum of light when the light source is in the first configuration, and a second spectrum of light when the light source is in the second configuration.

8. A dental light fixture for use with teeth restoration comprising:
-
an integrating sphere having an exit aperture; at least one light source housed within the integrating sphere for emitting light; and a collimating lens coupled to the exit aperture for collecting and directing the light emitted by the at least one light source; wherein the fixture emits a first spectrum of light when in a first configuration and a second spectrum of light when in a second configuration. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of restoring a tooth using dental restoration materials, comprising:
-
applying restoration materials to the tooth while illuminating the tooth with light emitted from a dental light fixture in a first configuration; and illuminating the tooth with light emitted from the dental light fixture in a second configuration once the materials have been applied to the tooth; wherein the light emitted from the fixture in the first configuration does not contain a spectrum of light having a substantial physical effect upon the restoration materials, and wherein the light emitted from the fixture in the second configuration contains a spectrum of light having a substantial physical effect upon the restoration materials. - View Dependent Claims (16, 17, 18, 19, 20)

21. An illumination device comprising:
-
an internally reflective enclosure; a first light source emitting light of a first wavelength within the internally reflective enclosure; a second light source emitting light of a second wavelength different from the first wavelength within the internally reflective enclosure; and at least one switch for selectively illuminating the first and second light sources. - View Dependent Claims (22, 23, 24, 25)
