A light unit configured to emit at least one wide-aperture light beam including a transmitter system, configured to emit at least one light beam, the beam(s) being emitted in an angular range of 360° around the transmitter system; a reflector system surrounding the transmitter system, arranged to receive each light beam propagating from the transmitter system and to reflect each light beam received towards the outside of the light unit. The reflector system includes a frame surrounding the transmitter system and bearing a reflecting surface extending around the transmitter system between two opposite edges of the frame, the reflector system and/or the transmitter system are mounted such that they can be moved relative to one another and such that they can be positioned relative to one another so as to modify the interception area of the beam emitted by the transmitter system along the reflecting surface of the reflector system.

[Object] To obtain output light with higher quality. [Solution] Provided is a light source device including: at least one light source unit (110) that emits substantially parallel light in a predetermined wavelength band; and a light guide unit (120, 130) that guides the light from the light source unit (110) toward a light collection spot (143). The light from the light source unit (110) is sequentially reflected by a concave mirror (121) and a convex mirror (122) and is guided toward the light collection spot (143) in the light guide unit (120, 130).

A rotation center decoupling type aiming lamp applied to a vehicle includes an aiming device in which an aiming axis spaced apart from an aiming point reference line of an aiming point axis at a distance of an aiming adjustment height is operated as a rotation center of the reflector, and an aiming angle is changed through an aiming point axis to which the reflector is attached by a reflector bracket, such that the rotation center of the reflector adjusting a light radiation direction may be formed at a position above or ahead of the aiming point reference line, thereby reducing an occupation space of the aiming device and securing stability of the aiming driving, and particularly, a sufficient rear shock absorption space may also be secured in the aiming lamp, thereby securing structural robustness while satisfying low-speed collision regulations.
