It is understood that the luminaire may also be square, and accordingly, the main light surface 310 is located around the square lampshade 300. When the lamp is assembled, the lamp housing 300 is assembled with the heat dissipation plate 100 (the heat dissipation plate 100 has the lamp beads mounted thereon), as shown in fig. 3 and 4, the main light surface 310 corresponds to the first region 110 of the heat dissipation plate 100, and the secondary light surface 320 corresponds to the second region 120 of the heat dissipation plate 100, that is, the light emitted by the lamp beads mounted in the first region 110 is emitted through the main light surface 310, and the light emitted by the lamp beads mounted in the second region 120 is emitted through the secondary light surface 320. The light output of the primary light surface 310 and the light output of the secondary light surface 320 are determined by the number of the lamp beads in the first area 110 and the second area 120. The number of the lamp beads in the first area 110 is greater than that of the lamp beads in the second area 120, so that the light emitting amount of the main light surface 310 is greater than that of the secondary light surface 320.
