Abstract
An ensemble light source includes multiple individual light sources arranged in an array pattern. The individual light sources may be controlled to provide different divergence profiles and/or optics may be used to provide different divergence profiles.
Claims19
An ensemble light source comprising:
- a base;
- multiple individual light sources arranged in an array pattern on the base, each of the individual light sources configured to emit visible light, the individual light sources imparting a predetermined divergence profile of the visible light emanating from the individual light sources, each individual light source comprising:
- at least one laser diode device comprising a gallium and nitrogen containing material configured to generate and output a laser beam of electromagnetic radiation;
- and
- a phosphor member arranged to receive the laser beam from the at least one laser diode device and configured to convert a portion of the electromagnetic radiation from a first wavelength to a second wavelength so as to emit visible light, wherein the visible light emitted from the individual light source comprises a mixture of wavelengths characterized by at least the first wavelength and the second wavelength;
- one or more drivers electrically coupled to the individual light sources and configured to control current to each of the individual light sources;
- movable spreading optics configured for arrangement either within or outside of an emission path of at least some of the individual light sources;
- and
- a heat sink coupled to the base;
- wherein the one or more drivers are further configured to control the predetermined divergence profile of the individual light sources,
- wherein a first group of the individual light sources are each configured to emit the visible light with a first divergence profile, and
- a second group of the individual light sources are each configured to emit the visible light with a second divergence profile different from the first divergence profile.

An ensemble light source comprising:
- a base;
- multiple individual light sources arranged in a circular pattern on the base, the individual light sources configured to emit visible light, each individual light source comprising:
- at least one laser diode device comprising a gallium and nitrogen containing material configured to generate and output a laser beam of electromagnetic radiation;
- and
- a phosphor member arranged to receive the laser beam from the at least one laser diode device and configured to convert a portion of the electromagnetic radiation from a first wavelength to a second wavelength that is longer than the first wavelength, wherein the visible light emitted from the individual light source comprises a mixture of wavelengths characterized by at least the first wavelength and the second wavelength;
- one or more drivers electrically coupled to the individual light sources and configured to control current to each of the individual light sources;
- movable spreading optics configured for arrangement either within or outside of an emission path of at least some of the individual light sources;
- and
- a heat sink coupled to the base;
- wherein a first group of the individual light sources are tilted by a first angle in a radial direction relative to an emission plane so that the visible light is emitted with a first divergence profile, and
- the second group of the individual light sources are configured to emit the visible light with a second divergence profile narrower than the first divergence profile.
