    摘要： A light-emitting device (200) includes a base member (211), light-emitting element (220), and a wavelength conversion member (240). Light-emitting element (220) is configured to emit light traveling in a lateral direction. The wavelength conversion member (240) is disposed at a lateral side of the light-emitting element (220). The wavelength conversion member (240) includes a wavelength conversion portion (241) and a surrounding portion (242). The wavelength conversion portion (241) having an incident lateral surface (241i) and an exit surface (241a) so that light is incident on the incident lateral surface (241i), undergoes wavelength conversion in the wavelength conversion portion (241), and exits through the exit surface (241a). The surrounding portion (242) includes a protrusion (242t) located above the light-emitting element (220), and protruding outwardly toward a light-emitting element side with respect to the incident lateral surface (241i) with the protrusion (242t) overlapping with the emission end surface (220a) of the light-emitting element (220) in a top view.

    摘要： A laser device includes a support, a first heat sink, a plurality of laser light sources attached to the support, and a plurality of electrodes bridged between the plurality of laser light sources and the first heat sink. Each of the plurality of laser light sources is movable with respect to the support. Each of the plurality of electrodes is electrically connected to one of the plurality of laser light sources at a first connection portion, and is thermally connected to the first heat sink at a second connection portion. In each of the plurality of electrodes, an extension part between the first connection portion and the second connection portion has flexibility, and a length of the extension part is larger than a linear distance between the first connection portion and the second connection portion.
