Abstract: An annular lamp assembly (100) and an operation box (1), the annular lamp assembly (100) comprising: a circuit board (101); a lampshade (200), which comprises an outer annular wall (210) and an inner annular wall (220) separately provided on the circuit board (101), and an annular band area (201) being formed between the outer annular wall (210) and the inner annular wall (220); a plurality of LED lamp beads (300), which are located on the circuit board (101) of the annular band area (201) and are arranged at intervals along the annular band area (201); and a button (400), which is provided in a space formed by the enclosing of the inner annular wall (220), and the button (400) being suitable for turning the LED lamp beads (300) on or off. The annular lamp assembly (100) can have the effect of defining a light-receiving area in a specific space on light emitted from the LED lamp beads (300), thereby reducing light leakage.
