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

Patent number: 11204160Abstract: A light source device includes a housing having a great length along a predetermined direction, a plurality of light emitting elements which are placed in the housing and are arranged along the predetermined direction, and one or more heat dissipation members which are placed in the housing and are thermally connected with the light emitting elements. A first intake port through which air is sucked into the housing is provided in one end in the housing. An exhaust port through which air is discharged to an outside is provided in the other end in the housing. A space where the other side in the predetermined direction faces the heat dissipation member is formed in the housing. A second intake port through which air is sucked into the space from the outside is provided in a side surface between the first intake port and the exhaust port in the housing.Type: GrantFiled: December 9, 2020Date of Patent: December 21, 2021Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Kyoichi Murayama, Keita Umeno, Hiroya Kashiwabara, Ryotaro Matui
