Abstract:
A compact LED lamp (1) is provided with a holder (20), an LED module (10) mounted on the holder (20), and a globe (70) covering the LED module (10). The holder (20) has a groove (21) surrounding the LED module (10) at a top surface (24a) of the holder (20), with a rim (70a) of the globe (70) inserted in the groove (21). When comparing an edge (D1) and an edge (D2) along a side wall (24c) of the groove (21), the edge (D1) is closer to an opening of the groove, and the edge (D2) is closer to a bottom of the groove. The edge (D2) is more recessed than the edge (D1) in a direction perpendicular to a direction of depth of the groove. Furthermore, the groove (21) has through-holes (22) at part of a bottom surface (24d) of the groove (21) to connect to a back surface (24b) of the holder (20). The groove (21) and the through-holes (22) are filled with adhesive (80).
