Patent number: 11959624Abstract: A light emitting device includes a housing; a light source unit; and a cooling unit provided in the housing to discharge heat to an outside of the housing by means of a gas, the heat being generated by the light source unit. The cooling unit includes an introduction portion, a heat exchange portion, and a circulation portion that guides the gas from the introduction portion to the heat exchange portion. The circulation portion includes a first flow path receiving the gas from the introduction portion, and a second flow path receiving the gas from the first flow path, and being connected to the heat exchange portion. The first flow path includes a portion having a flow path area larger than a flow path area of the introduction portion.Type: GrantFiled: September 10, 2020Date of Patent: April 16, 2024Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Kyoichi Murayama, Yoshiteru Miyamoto, Ryotaro Matui, Hiroya Kashiwabara
