1. A lighting device comprising:
a first light emitter comprising a first light-emitting element with a p-n junction and a first side cover being directly arranged on a peripheral side surface of the first light-emitting element and partly covering the peripheral side surface of the first light-emitting element to shield and/or reflect light inward toward the first light-emitting element; and
a second light emitter comprising a second light-emitting element with a p-n junction and a second side cover being directly arranged on a peripheral side surface of the second light-emitting element and partly covering the peripheral side surface of the second light-emitting element to shield and/or reflect light inward toward the second light-emitting element,
wherein the first light emitter and the second light emitter are disposed to face each other at uncovered side portions that are uncovered by the first side cover and the second side cover.
