Abstract:
1. A linear white light source comprising: a base having a flat surface; a plurality of light emitting diode chips linearly disposed on the flat surface of the base and each generating ultraviolet light having a wavelength of not less than 330 nm nor more than 410 nm; and a phosphor layer continuously formed on the flat surface of the base to cover the plural light emitting diode chips and including a red light emitting phosphor, a green light emitting phosphor, and a blue light emitting phosphor, wherein the plural light emitting diode chips are disposed at an interval of 1 mm or more and 5 mm or less, and wherein the phosphor layer has a flat upper surface, and each of heights from the flat surface of the base to the flat upper surface of the phosphor layer in a first portion on which the light emitting diode chip is disposed and a second portion on which the light emitting diode chip is not disposed is in a range of 0.5 to 2 mm.
