Abstract
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.
