Japanese Patent JP2022041669

A

To provide a performance lighting device capable of performing lighting up having a higher performance property.SOLUTION: A performance lighting device includes: a case including a non-light transmissive body part having a space inside and having openings on a front surface, and a light transmissive light projection window for blocking the openings; and a light source part provided in the space of the case to emit light toward in front of the case through the light projection window. The light source part has a plurality of light source groups composed of a plurality of light sources arranged in a first direction orthogonal to a front-rear direction. The plurality of light source groups is arranged in a second direction orthogonal to the front-rear direction and the first direction. The case has a light shielding part for regulating spread of light emitted from the plurality of light sources in the second direction by being provided in the light projection window and arranged at least partially in front of an area among the plurality of light source groups arranged in the second direction without being located in front of the plurality of light source groups.SELECTED DRAWING: Figure 1
