In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings.

Please refer to FIG. 1A, FIG. 1B and FIG. 2 . FIG. 1A is a perspective assembled view of the lamp 1 according to an embodiment of the present invention. FIG. 1B is an exploded perspective view showing the lamp 1 in FIG. 1A. Fig. 2 is a cross-sectional view showing the lamp 1 of Fig. 1A along line 2-2'.

As shown in FIGS. 1A to 2 , in the present embodiment, the lamp 1 includes a susceptor 10 and a light-emitting module 12 . The base 10 of the luminaire 1 has a hollow portion 100. The hollow portion 100 of the base 10 has a first opening 100a, a second opening 100b, and a third opening 100c. The first opening 100a and the second opening 100b of the hollow portion 100 are respectively located on opposite sides of the base 10 (ie, the lower side and the upper side of FIG. 2), and the third opening 100c and the second opening 100b of the hollow portion 100 are located at the base The same side of the seat 10.

Therefore, the light emitted by the first module 100a of the light-emitting module 12 can be used as the direct illumination of the lamp 1. In addition, since the beam angle of the light emitting module 12 covers at least a portion of the first reflective surface 104 and the second reflective surface 106 of the susceptor 10 , a part of the light emitted by the light emitting module 12 passes through the susceptor 10 . The first reflecting surface 104 is reflected away from the second opening 100b of the hollow portion 100, and another portion of the light is reflected by the second reflecting surface 106 of the base 10 to be separated by the third opening 100c of the hollow portion 100. Thereby, the light emitted by the second opening 100b and the third opening 100c of the hollow portion 100 can be used as the indirect illumination of the lamp 1.

It can be seen that the lamp 1 of the present invention has a secondary optical design in the hollow portion 100 of the base 10, so that the lamp 1 can create an effect of light and shadow on both the upper and lower sides. In particular, the light emitted by the second opening 100b and the third opening 100c is reflected by the first reflecting surface 104 and the second reflecting surface 106 for the first time, and then by the ceiling (not shown) for the second time. The reflection makes it possible to provide better light softening effects than the existing lamps on the market, making the interior space more beautiful.
