| Title: |
Simple Light-Blocking and Air-Exhausting Device, and Stage Light Fixture Including Same |
| Abstract: |
A simple light-blocking and air-exhausting device includes a ventilation plate and a light-blocking plate arranged oppositely and spaced apart from each other. The ventilation plate is provided with an air vent formed by die-cutting the ventilation plate, and vertical projection of the light-blocking plate on the ventilation plate overlaps the air vent. The vertical projection of the light-blocking plate on the ventilation plate overlaps the air vents on the ventilation plate, so that the light-blocking plate can prevent light from leaking out of the air vents, while air flow can flow out from a gap between the light-blocking plate and the ventilation plate. |
