Bulb-Type LED Lamp

摘要

An LED lamp according to an embodiment includes an LED module, a base body, a first globe, a second globe and a light guide body. In the LED module, a plurality of LEDs are mounted on a substrate. The base body holds the LED module. The first globe is arranged to surround the outer circumference of the substrate. A bore diameter (D2) of a first joining end is larger than a bore diameter (D1) of an attachment section. The second globe includes a second joining end attached to the first joining end and covers the emission side of the LEDs. A proximal end of the light guide body is fixed to a side where the LEDs are arranged. A distal end section of the light guide body has a diameter larger than the bore diameter (D1) of the attachment section of the first globe.
