Bulb-Type LED Lamp

An LED lamp comprising:

• an LED module in which a plurality of LEDs are arranged in a ring shape and mounted on a substrate;
• a base body configured to hold the LED module and thermally connected to the LED module;
• a first globe arranged to surround an outer circumference of the substrate, a bore diameter of a first joining end of the first globe extending to an emission side of the LEDs being larger than a bore diameter of an attachment section fixed to the base body;
• a second globe including a second joining end attached to the first joining end and configured to cover the emission side of the LEDs;
• a light guide body including a proximal end fixed to a side where the LEDs are arranged and a distal end section having a diameter larger than the bore diameter of the attachment section of the first globe and arranged further on the substrate side than the first joining end;
• and
• fins including, at ends on the substrate side, inclined sections arranged perpendicularly to the substrate in an outer circumference of the base body and formed to be reduced in height toward the substrate, the fins radiating heat generated by the LEDs.
