Abstract
This lighting apparatus includes three or more LEDs arranged in a row. Each of the LEDs emits light of a color different from that of an LED adjacent to itself, and the LEDs include an LED having a relatively wide light distribution angle and others of the three or more LEDs each having a relatively narrow light distribution angle. The one LED is arranged in an inner portion in the row of the other LEDs. In this configuration, light emitted from the one LED is mixed well with lights emitted from the respective other LEDs adjacent to the one LED, and thus, color unevenness of illuminating light can be reduced.
