Abstract
In a lighting unit, fluorescent lights and LEDs of different spectroscopic characteristics are alternately arranged in a direction X on an irradiation plane. Light sources of equal light intensity are arranged in a certain pitch for the fluorescent lights such that a uniform light amount is achieved around end portions in the direction X. The LEDs include LEDs aligned on a bottom surface of a chassis and LEDs arranged on an inner sidewall surface of the chassis. As a result, a lighting unit having a uniform amount of light across an entire irradiation plane is achieved.
