Light source device

A light source device comprising:

• a combined body comprising light emitting portions including:
• a first light emitting portion comprising a first light emitting element, and
• a second light emitting portion provided separately from and along an outer periphery of the first light emitting portion in a plan view, the second light emitting portion comprising a plurality of second light emitting elements;
• and
• a lens disposed above the combined body;
• wherein:
• the first light emitting element and the plurality of second light emitting elements are arrayed in first and second directions that are perpendicular to each other,
• the first light emitting element and the plurality of second light emitting elements are controllable to be lit independently, and
• the light source device is configured such that alight output of the first light emitting portion and a light output of the second light emitting portion are adjustable, and the light source device is configured to operate in a mode in which both the first light emitting portion and the second light emitting portion output light, and the light output from one of the first light emitting portion or the second light emitting portion is greater than the light output of the other of the first light emitting portion or the second light emitting portion.
