Abstract

A lamp unit configuring a light source device capable of efficiently cooling a light source by a simple structure includes a light source and a plurality of air outlets for discharging the cooling air for cooling the light source. The plurality of air outlets include a first air outlet for discharging the cooling air in a first direction and a second air outlet for discharging the cooling air in a second direction. The cooling air discharged through the first air outlet is different in airflow rate from the cooling air discharged through the second air outlet, and the first direction is different from the second direction when viewed in the direction of the optical axis of the light source.

Description

technical field [0001] The present invention relates to a light source device and a projector, and is further particularly specified as an efficiently cooled light source device and a projector equipped with the light source device. Background technique [0002] In recent years, along with the high performance of devices such as projectors including light source devices as structural components, higher luminance has been demanded for light source devices. Furthermore, in order to respond to the demand for higher luminance, there is a tendency to use a light source with a large amount of light as a light source device. Such a light source with a large amount of light often generates a large amount of heat, and effective cooling is required. [0003] In contrast, for example, a light source device has been proposed in which an inflow path and an outflow path of a cooling fluid are arranged substantially parallel to a surface of a light-emitting element base on which a light-e...
