[0002] With the rapid development of modern science and technology, the application of projection lamp technology in various fields is becoming increasingly widespread, especially in stage performances, advertising, home entertainment and commercial displays, etc. Projection lamps are deeply loved by users for their unique visual effects and flexible display methods. However, there are some inherent defects in the design of the light source lamp set of traditional projection lamp equipment, such as insufficient light source brightness, poor heat dissipation effect, non-adjustable light direction, single pattern or text display, etc. These problems limit the application range and use effect of the projection lamp to some extent.

[0003] In terms of light source brightness, the light source of traditional projection lamps usually adopts halogen lamps or fluorescent lamps, etc. The brightness of these light sources is limited, and the energy consumption is high, which not only increases the use cost, but also limits the clarity and brightness of the projection picture. At the same time, due to the large heat generation of the light source, the traditional heat dissipation method often fails to effectively reduce the temperature of the light source, resulting in a shortened service life of the light source, and even may cause safety hazards.

[0004] In terms of light direction adjustment, the light direction of traditional projection lamps is usually fixed and cannot be flexibly adjusted according to actual needs. This not only limits the use scene of the projection lamp, but also may cause the projection picture to have shadows or uneven brightness, affecting the viewing experience of the audience.

[0073] The present application can be used in the field of projection lamp technology, and can also be used in other fields applicable to the present application.

[0074] Embodiment 2: Reference Figures 8-9The improved embodiment is based on the first embodiment. The LED light source lamp group is applied to the technical field of projection lamps. In order to adjust the angle of the lamp group mechanism, a transmission assembly is connected to the side of the two support plates 5 close to each other. The transmission assembly includes a bracket 38 fixedly connected with the two support plates 5 respectively. A support shaft 39 is fixedly arranged in the bracket 38. A gear arm 40 is rotatably arranged on the support shaft 39. The top and bottom of the gear arm 40 extend above and below the bracket 38 respectively. A second stepper motor 43 is fixed to one side of the support plate 5. A gear 44 is fixedly arranged on the output shaft of the second stepper motor 43. The gear 44 is engaged with the gear arm 40.

One side of the connecting plate 42 extends into the connecting ring 41 and is slidingly connected with the inner wall of the connecting ring 41. By starting the second stepper motor 43, the gear 44 can be driven to rotate, thereby driving the gear arm 40 to rotate, and driving the connecting plate 42 to perform arc-shaped motion. Under the transmission cooperation of the connecting plate 42 and the connecting ring 41, the lamp group mechanism can be adjusted in angle, and the light emitted by the lamp group mechanism can be irradiated to the specified area.

[0075] A limiting plate 15 is also fixed in the mounting ring 8. One side of the limiting plate 15 is fixed with a support rod 16. A sealing plate 17 is slidingly arranged on the support rod 16. The sealing plate 17 is provided with a fluorine rubber O-ring. The sealing plate 17 is sealingly attached to one side of the mounting ring 8 (through the fluorine rubber O-ring). A connecting cover 18 is fixed to one side of the sealing plate 17. One end of the support rod 16 extends into the connecting cover 18 and is slidingly connected with the inner wall of the connecting cover 18. A compression spring 19 is arranged on the support rod 16 and located in the connecting cover 18. The two ends of the compression spring 19 are fixedly connected with one side of the sealing plate 17 and one end of the support rod 16 respectively. When the water cooling method is used to cool the heat dissipation fins, the mounting ring 8 can be blocked by the sealing plate 17 to form a relatively closed space between the mounting ring 8 and the reflector cover 13. At this time, when the cooling liquid is delivered between the reflector cover 13 and the mounting ring 8, the cooling liquid will stop flowing under the blocking action of the sealing plate 17, so that the cooling liquid can fully absorb the heat on the heat dissipation fins, and better and more stable cooling and heat dissipation of the LED lamp beads 21 can be realized.

[0076] The application provides a use method of the projection lamp, which comprises the following steps:

[0077] S1, first set the device in a predetermined position, then can be driven by starting the motor 4 to adjust the disc 3 rotation, the light emitted by the light group mechanism adjustment direction, so that the light emitted by the light group mechanism can be illuminated on the corresponding wall or curtain, while you can insert the corresponding mounting hole after the fixed ring 33, at this time can make the card strip 32 and the corresponding card slot 35 card, synchronous can make the first magnet ring 36 and the second magnet ring 37, so as to realize the brake positioning of the fixed ring 33, so as to realize the installation of the fluorescent plate 34;

[0078] S2, after the orientation adjustment of the light group mechanism is completed, the second step motor 43 is started to drive the gear 44 to rotate, which can drive the gear arm 40 to rotate under the meshing transmission of the gear arm 40, so as to drive the connecting plate 42 to move in arc shape, which can drive the light group mechanism to adjust the angle under the transmission cooperation of the connecting plate 42 and the connecting ring 41;

[0079] S3, after the adjustment of the light group mechanism is completed, the LED lamp bead 21 can be energized to emit light, the light is output by the reflector 13, then the light is output by the fluorescent plate 34 corresponding to the position of the lamp shell 6, and different patterns or characters can be engraved on the fluorescent plate 34 in advance, so as to irradiate the patterns or characters on the projected wall or curtain under the transmission of light, so as to display different patterns or characters;

[0080] S4, the first step motor 29 is started to drive the transmission shaft 30 to rotate, which can drive the mounting frame 31 to rotate, so that the fluorescent plate 34 can move to the position corresponding to the opening of the lamp shell 6 after being installed in the corresponding mounting hole, so as to display different pictures or characters;

[0081] S5, when the fluorescent plate 34 needs to be replaced, only the corresponding fixed ring 33 is extracted, the first magnet ring 36 and the second magnet ring 37 are separated, and the new fluorescent plate 34 can be easily taken out and replaced;

[0082] S6. During the operation of the LED bead 21, the coolant in the water tank 23 can be drawn out by starting the circulation pump 24. Then, the coolant is transported to the annular pipe 26 through the first hose 25, and then to the lamp housing 6 through multiple connecting pipes 27. This allows coolant to be injected into the lamp housing 6, cooling the lamp cover 12 and multiple heat dissipation fins. At this time, the mounting ring 8 is sealed by the sealing plate 17 to create a relatively enclosed space between the mounting ring 8 and the reflector 13. When the coolant is transported between the reflector 13 and the mounting ring 8, the coolant will be contained within the sealing plate 17. Under the obstruction, the flow stops, allowing the coolant to fully absorb the heat on the heat dissipation fins, thus achieving better and more stable cooling of the LED beads 21. When the coolant needs to be replaced, the circulation pump 24 can be started to inject coolant into the lamp housing 6. At this time, the sealing plate 17 can be moved under the action of hydraulic pressure, thus removing the sealing plate 17 from the mounting ring 8. Therefore, the coolant can flow out from the mounting ring 8, and then flow back to the water tank 23 through the tapered bend 22 and the second hose 28, thus enabling the coolant to be recycled and continuously and stably dissipated from the lamp assembly mechanism.

[0083] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 4, LED beads 21, circulating pump 24, first stepper motor 29 and second stepper motor 43 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0084] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
