Abstract: A camera flash comprises a solid-state light source (laser chip) operable to emit excitation light having an emission peak wavelength in a first wavelength range and a photoluminescence wavelength conversion component located remote to the light source. The photoluminescence wavelength conversion component comprises at least one photoluminescence material (phosphor) that is excitable by the excitation light and in response emits light having an emission peak wavelength in a second wavelength range. The light source is configured such that excitation light is incident on an area of the photoluminescence wavelength conversion component less than about 0.01 mm2. The photoluminescence wavelength conversion component can comprise a light reflective or light transmissive component.
