Abstract: A light emitting device includes: a member having a first surface facing in one direction and a second surface facing an opposite side to the first surface; a light emitter that is disposed at the first surface, generates heat due to light emission, and has a lower stiffness than the member; and a heater that is disposed at the second surface of the member, and heats the member from the second surface.

Abstract: A light emitting device includes: a base that extends in one direction, and has an opening; plural light emitting units that are disposed to be displaced from each other in the one direction on the front surface side of the base, the light emitting units each including a support that extends in the one direction, and plural light sources that are disposed in the one direction on the support; and an air blowing unit that blows air toward the light emitting units through the opening.

Abstract: A light emitting device includes a light emitting unit in which a resin housing extending in one direction holds a light emitting element emitting light in a light emitting direction intersecting the one direction, a suppressing member that extends in the one direction and suppresses deformation of the housing caused by heat, the suppressing member having a linear expansion coefficient different from a linear expansion coefficient of the housing, and a fixing portion that fixes the housing and the suppressing member to each other at a position overlapping, in the light emitting direction, a neutral axis of the housing or the light emitting unit or a neutral axis of the suppressing member in the light emitting direction, at plural places separated away from each other in the one direction or in a state of extending in the one direction.

Abstract: A light emitting device includes a resin housing that extends in one direction and holds a light emitting unit emitting light upward in a height direction intersecting the one direction, the housing having, on an upper side and a lower side of each of both end portions in the one direction, a positioned portion, which comes into contact with a positioning member in the height direction, and a biased portion, which receives a biasing force from a biasing unit biasing the housing to bring the positioned portion into contact with the positioning member, and a suppressing member that extends in the one direction and is fixed to the housing to suppress deformation of the housing, at least one end portion of the suppressing member in the one direction being interposed between the biased portion and the biasing unit.
