Abstract: A light emitting module includes a light source, a first lens configured to transmit light from the light source and including at least a portion that is elastically deformable, and an actuator configured to move the first lens in a direction along an optical axis of the first lens. The light source includes a contact portion with which the first lens comes into contact. The actuator is configured to move the first lens to change a state of the first lens relative to the contact portion of the light source.

Abstract: A light source device includes a substrate having an upper surface including mounting areas; light-emitting elements on the upper surface of the substrate in the mounting areas; a light-shielding member on an upper surface of at least one of the light-emitting elements; and a light guide member defining, in a lower surface, first recesses and at least one second recess. The light-emitting elements are disposed on the mounting areas in the first recesses. Light emitted from the light-emitting elements enters the light guide member through first inner surfaces defining the first recesses, is reflected at second inner surfaces defining the second recess toward the upper surface of the light guide member, is emitted from the upper surface of the light guide member, and illuminates illumination areas at positions that are point-symmetrical, with respect to a point above the substrate, to the mounting areas where the light-emitting elements are disposed.
