Abstract
An illumination apparatus includes: a solid-state light source; a Peltier element configured to cool the solid-state light source; a light amount sensor configured to detect an amount of a light emitted from the solid-state light source; a power consumption monitor configured to monitor power consumptions of the solid-state light source and the Peltier element; and a power controller configured to control powers supplied to the solid-state light source and the Peltier element. The power controller controls the powers supplied to the solid-state light source and the Peltier element, on the basis of the light amount detected by the light amount sensor and a sum of the power consumptions of the solid-state light source and the Peltier element.
