Abstract:

A stage lamp having a light shading device, comprising a lamp holder. The lamp holder comprises a light source, the light shading device, and a light emitting lens. The light shading device is mounted between the light source and the light emitting lens. The light shading device comprises a foldable light shading curtain (100) and a driving mechanism (200) for driving the light shading curtain (100) to be unfolded or folded. The light shading curtain (100) is provided with a plurality of folding surfaces (120) which are connected in sequence. When the light shading curtain (100) is in a folded state, every two adjacent folding surfaces (120) are overlapped with each other. According to the light shading device, by controlling the light shading curtain (100) to be unfolded when the stage lamp is in a standby state or a non-working state, sunlight or strong light entering the lamp through the light emitting lens can be shaded, and therefore the light source of the stage lamp is protected. When the stage lamp is used, the light shading device controls the light shading curtain (100) to be folded. The occupied space of the light shading device is saved, and the stage lamp is simple in structure and convenient to operate.
