摘要 |
An LED lamp (1) according to an embodiment includes an LED module (11), a base body (12), a first globe (131), a second globe (132), and a light guide body (14). In the LED module (11), a plurality of LEDs (112) are mounted on a substrate (111). The base body (12) holds the LED module (11). The first globe (131) is arranged to surround the outer circumference of the substrate (111). A bore diameter (D2) of a first joining end (131c) is larger than a bore diameter (D1) of an attachment section (131b). The second globe (132) includes a second joining end (132c) attached to the first joining end (131c) and covers the emission side of the LEDs (112). A proximal end (142a) of the light guide body (14) is fixed to a side where the LEDs (112) are arranged. A distal end section (142b) of the light guide body (14) has a diameter larger than the bore diameter (D1) of the attachment section (131b) of the first globe (131). |
