The integrated control circuit holds light emitting intensity indicating value target variation information, and determines the variation of the light emitting intensity indicating values, in accordance with the light emitting intensity indicating value target variation information belonging to one appearance mode of the wavelength deviation indicating values assumed on a basis of an actual mode of the generated wavelength deviation indicating values.

摘要： The wavelength of fundamental wave light emitted from a semiconductor laser is converted by a wavelength conversion element, and the wavelength-converted light is emitted. A power supply circuit feeds electric power to the semiconductor laser. A control part controls an amount of electric power to be fed to a heater such that the wavelength conversion element becomes a temperature that optimizes the wavelength conversion efficiency. Temperatures detected by an element temperature detector and a light source part temperature detector are introduced to the control part, and the control part takes a wavelength conversion element temperature, at which a temperature detected by the light source part temperature detector is minimum, as a set temperature that makes the wavelength conversion efficiency optimal, and feedback-controls the wavelength conversion element temperature such that the wavelength conversion element temperature is at the set temperature by controlling the heating quantity of the heater.

摘要： A light source unit including: a plurality of elemental light sources each including a light emitting element and a drive circuit; a control circuit configured to control the drive circuit; and a luminous flux characteristic measurement section configured to measure received output luminous fluxes to generate luminous flux chromaticity-intensity correlation data. The control circuit generates a single-color color-phase indicating value, based on the luminous flux chromaticity-intensity correlation data. The control circuit determines a ratio of intensity of additional light to intensity of main component light to allow the single-color color-phase indicating value to become equal to a target value thereof, and generates an integrated color-phase indicating value, based on the luminous flux chromaticity-intensity correlation data. The control circuit performs feedback control on the drive circuits to allow a difference between the integrated color-phase indicating value and a target value thereof to be small.
