摘要

A lamp (1) including a base (10) and a light-emitting module (12) is disclosed. The base (10) has a hollow portion (100). The hollow portion (100) has a first opening (100a) and a second opening (100b). The first opening (100a) and the second opening (100b) are respectively located at two opposite sides of the base (10). The base (10) further includes a mounting surface (102) and a reflective surface (104, 106) located within the hollow portion (100). The mounting surface (102) faces toward the first opening (100a). The reflective surface (104, 106) substantially faces toward the mounting surface (102) and the second opening (100b). The light-emitting module (12) is disposed at the mounting surface (102) and emits a light toward the first opening (100a). A part of the light is reflected by the reflective surface (104, 106) and then leaves from the second opening (100b).
