  • Programmable de-fogger system for a light projector
    Patent number: 8770764
    Abstract: A light projector for operation during a show that contains theatrical haze. The light projector may include a light source, a lens, a fan, and a housing having an inner chamber. The lens may have a first side and a second side. The first side of the lens may be contained within the inner chamber of the housing. The second side the lens may be outside of the inner chamber of the housing. The fan may be configured to be operated to generate air flow inside the inner chamber of the housing. A substantial portion of the air flow may be directed to impinge upon the first side of the lens to cause de-fogging of theatrical haze condensate on the first side of the lens.
