A fluorescent tube type LED lamp includes an elongated lamp body that has a largest dimension in a longitudinal direction, a light source substrate mounted on the lamp body, a light transmissive cover attached to the lamp body, and an LED unit mounted on the light source substrate such that the LED unit extends in the longitudinal direction of the lamp body. The LED unit includes a plurality of LED chips mounted on the light source substrate, and a transparent encapsulant encapsulating the LED chips. The encapsulant is molded such that the encapsulant is raised from the light source substrate. The LED unit radiates light from an entire surface of the encapsulant in an angular range including a region lateral to the lamp body.

摘要:
In a light emitting module, each of a first light wavelength conversion member, a second light wavelength conversion member, and a third light wavelength conversion member converts the wavelength of the light emitted by a semiconductor light emitting element to emit the light within a wavelength range different from the others. Each of the first light wavelength conversion member, the second light wavelength conversion member, and the third light wavelength conversion member is formed into a plate shape and is laminated such that the light emitted by the semiconductor light emitting element passes through each of them in descending order of the average wavelength of the light whose wavelength has been converted.
