Abstract
A dynamic projection light includes an end to end long strip of film, a film guiding box, a first lens support and a second lens support which are arranged on both sides of the film guiding box, and a driving device provided with one or more touch parts. The film guiding box defines a guiding crack through which the film is capable of passing and being guided, one or more through holes and one or more insertion holes communicating with the guiding crack. The one or more touch parts are capable of extending into the one or more insertion holes to contact with the film so that the driving device can drive the film to move in the film guiding box, enabling patterns on the film to be projected in sequence.
Claims9
A dynamic projection light, comprising:
- an end to end long strip of film;
- a film guiding box configured for guiding a moving direction of the film, defining a guiding crack through which the film is capable of passing and being guided, one or more through holes and one or more insertion holes communicating with the guiding crack;
- a first lens support and a second lens support configured on two sides of the film guiding box and configured for holding lenses arranged in an optical axis or in one more optical axises, the lenses facing a part of the film through the one or more through holes;
- a light panel provided with at least one light source, the light panel being fixed on a side, away from the film guiding box, of the first lens support, and the at least one light source being configured in or near the optical axis(s);
- a driving device comprising one or more touch parts capable of extending into the one or more insertion holes to contact with the film so that the driving device drives the film to move in the film guiding box, enabling patterns on the film to be projected in sequence;
- and
- a control circuit board for controlling the at least one light source and the driving device;
- wherein the film guiding box comprises a substantially plate-shaped first cover and a substantially plate-shaped second cover connected to the first cover, a gap is defined between the first cover and the second cover and forms the guiding crack, and the one or more insertion holes and the one or more through holes are through holes penetrating through the first cover and the second cover;
- wherein a fixing piece extends substantially perpendicularly from a surface, away from the second cover, of the first cover, and the fixing piece is located on the periphery of one of the one or more insertion holes;
- wherein the driving device further comprises a motor, a second gear connected with an output shaft of the motor, a rotating shaft, and a third gear sleeved on the rotating shaft and meshed with the second gear;
- the one or more first gears are sleeved on the rotating shaft;
- one end of the rotating shaft is rotatably connected with the fixing piece, the other end of the rotating shaft is rotatably connected with a middle plate.
