Abstract
An LED lamp has a lamp body, a base provided on one end of the lamp body, a light transmissive cover provided on an opposite side of the lamp body from the base, a light source substrate disposed inside the light transmissive cover, and at least one LED unit mounted on the light source substrate. The LED unit has an LED chip and a light transmissive encapsulant encapsulating the LED chip. The LED chip is mounted on the light source substrate. 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 around a periphery of the LED unit.
