[0002] A beam lamp, also known as an effect lamp, is a lighting device widely used in occasions such as stages, performances, and films. Its main function is to focus light into a narrow and intense beam through a condenser lens, so as to effectively illuminate a specific area or focus on a certain performer. Such a lamp is particularly important in outdoor stage lighting because it can not only provide strong illumination but also create rich visual effects;

[0003] The common technical limitation of outdoor stage lighting equipment is insufficient waterproofness. Traditional beam lamps mostly adopt a design with weak sealing, making it difficult to cope with changing outdoor weather conditions such as wind and rain attacks and rain immersion. This will not only reduce the service life of the lamp but also cause a decline in the beam effect and even pose a safety hazard. Summary of the Invention

Detailed implementation manners

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Embodiment 1

[0027] The present invention provides a waterproof beam lamp for outdoor stage lighting, as Figures 1 to 5 shown, including a fixing frame 1. The fixing frame 1 is a support structure for the entire device and is installed at a designated position on the outdoor stage. The top end of the fixing frame 1 is rotatably connected to an adjusting frame 2. The adjusting frame 2 is installed at the top end of the fixing frame 1 by a rotational connection method and can be adjusted left and right to meet the lighting requirements at different angles. A waterproof cutting lamp 3 is movably installed inside the adjusting frame 2. The outer shell of the waterproof cutting lamp 3 is integrally manufactured, changing the existing method of assembling with multiple structures. This method effectively improves the overall sealing performance. The lighting angle is adjusted by the rotation of the adjusting frame 2, and by moving the waterproof cutting lamp 3, the waterproof cutting lamp 3 swings up and down. Both end faces of the waterproof cutting lamp 3 are installed with cover plates 4 through bolts. The cover plates 4 are used to fix and protect the ends of the waterproof cutting lamp 3. The light-emitting end of the waterproof cutting lamp 3 is sleeved with a head cover 7, and the head cover 7 is used to protect the lamp head and guide the light. The bottom end of the waterproof cutting lamp 3 is sleeved with a tail cover 6, and the tail cover 6 is used to protect the bottom of the lamp body and achieve sealing at the connection with the waterproof cutting lamp 3 through a sealing ring;

[0028] Inside the inner wall of the cover plate 4, a dynamic adjustment sealing structure 5 is fixedly installed. The dynamic adjustment sealing structure 5 includes a positioning cover 53 fixedly installed inside the cover plate 4, which is used for fixing an object. Inside the positioning cover 53, a pressure sensor 54 is installed, which is used to monitor the pressure change in the airbag 55. At the top of the pressure sensor 54, an airbag 55 is installed, which is used to compensate for the pressure drop caused by the wear of the sealing ring. At the bottom of the airbag 55, an air pump 51 is connected, which is used to supplement gas into the airbag 55. At the top of the airbag 55, an extrusion plate 510 is adhesively connected, which is used to support the extrusion strip 512. At the top of the extrusion plate 510, a column 511 is fixedly installed, and at the top of the column 511, an extrusion strip 512 is fixedly installed, which is used to extrude the sealing gasket 513. At the top of the extrusion strip 512, a sealing gasket 513 is adhesively connected, which is used to fill the gap in the sealing groove 8.

[0029] As Figure 2 and Figure 3 shown, on both sides of the cover plate 4, sealing grooves 8 are provided, and the extrusion strip 512 and the sealing gasket 513 are located inside the sealing grooves 8;

[0030] When the sealing gasket 513 is squeezed, at this time the sealing gasket 513 deforms, and after the sealing gasket 513 deforms, it blocks the gap in the sealing groove 8, and makes the connection between the cover plate 4 and the waterproof cutting lamp 3 be squeezed and sealed.

[0031] As Figure 4 and Figure 5 shown, at the bottom of the airbag 55, an assembly pipe 56 is embedded and installed. At the bottom of the assembly pipe 56, a connecting pipe 52 is connected, and a fixed connection is made between the air inlet end of the connecting pipe 52 and the air outlet end of the air pump 51;

[0032] When the air pump 51 operates, it makes the gas enter the inside of the assembly pipe 56 through the connecting pipe 52, and finally enters the inside of the airbag 55 through the assembly pipe 56, so that gas is added to the inside of the airbag 55.

[0033] As Figure 4 and Figure 5 shown, a one-way valve 57 is fixedly installed inside the assembly pipe 56. Under the action of the one-way valve 57, it makes the gas can only enter the inside of the airbag 55 and there will be no problem of backflow.

[0034] As Figure 4 and Figure 5 shown, in the middle of the outside of the airbag 55, an exhaust pipe 58 is fixedly installed. The exhaust pipe 58 penetrates through the positioning cover 53, and a pressure valve 59 is embedded and installed inside the exhaust pipe 58;

[0035] When the pressure inside the airbag 55 increases due to temperature changes, and at this time the pressure reaches the threshold value of the pressure valve 59, the pressure valve 59 is opened. After the pressure valve 59 is opened, the gas is discharged, so that the pressure inside the airbag 55 is relieved, and further the pressure inside the airbag 55 is kept consistent.

[0036] As Figure 4 and Figure 5 shown, the exhaust pipe 58 and the assembly pipe 56 are perpendicular to each other. A hole is provided in the middle of the pressure sensor 54, and the assembly pipe 56 is located inside the hole, which is convenient for installing the assembly pipe 56. And the perpendicularity between the exhaust pipe 58 and the assembly pipe 56 enables the gas to flow and changes the flow difficulty of the gas.

[0037] As Figure 4 and Figure 5 shown, as an optimization of the above technical solution, the shape of the extrusion plate 510 is T-shaped, and the outer side of the extrusion plate 510 is in close contact with the inner wall of the positioning cover 53, which is convenient for extruding the airbag 55 inside the positioning cover 53 and preventing the problem of uneven force on the airbag 55.

[0038] As Figure 4 and Figure 5 shown, ventilation holes are symmetrically arranged at equal distances on the outer surface of the tail cover 6. A sealing ring is provided at the connection between the tail cover 6 and the waterproof cutting lamp 3, which can seal the connection between the tail cover 6 and the waterproof cutting lamp 3 and can dissipate heat inside the waterproof cutting lamp 3.

[0039] As Figure 4 and Figure 5 shown, a sealing glue is coated at the connection between the exhaust pipe 58 and the positioning cover 53. A filter screen is provided on one end face of the exhaust pipe 58. The filter screen can prevent external objects from entering the exhaust pipe 58, and under the action of the sealing glue, the connection between the exhaust pipe 58 and the positioning cover 53 is kept stable and sealed.

[0040] Working principle: In practical application, the device first places the fixing frame 1 at a predetermined location of the outdoor stage, and then installs the adjustment frame 2 on the top of the fixing frame 1 by means of a rotating connection. By rotating the adjustment frame 2, the lighting angle of the waterproof cutting lamp 3 can be precisely controlled. At the same time, the up and down swinging function of the waterproof cutting lamp 3 further enhances the flexibility of lighting. Next, the cover plate 4 is fixed to both ends of the waterproof cutting lamp 3 by bolts to ensure the stability and protection of the ends of the lamp body. Next, the head cover 7 is installed at the light-emitting end of the waterproof cutting lamp 3 to protect the lamp head and optimize the light distribution. Finally, the tail cover 6 is installed at the bottom end of the waterproof cutting lamp 3, and is tightly connected to the lamp body by a sealing ring to ensure the sealing of the overall structure, which can facilitate multi-dimensional adjustment of the angle of the waterproof cutting lamp 3, thereby making the irradiation range of the waterproof cutting lamp 3 wider and further facilitating the use of the waterproof cutting lamp 3.

[0041] During the installation of the cover plate 4 and the waterproof cutting lamp 3, the sealing gasket 513 will be squeezed and deformed. The deformed sealing gasket 513 can effectively fill the gap of the sealing groove 8, thereby realizing a tight seal at the connection between the cover plate 4 and the waterproof cutting lamp 3. At the same time, the squeezing of the sealing gasket 513 will push the squeezing strip 512 to move, and then drive the squeezing plate 510 to move through the column 511. The movement of the squeezing plate 510 will produce an squeezing effect on the airbag 55, causing the airbag 55 to be compressed, thereby causing a pressure change on the pressure sensor 54. When the pressure value detected by the pressure sensor 54 exceeds the set threshold, the pressure valve 59 will be triggered to open, thereby releasing the gas inside the airbag 55 to achieve pressure relief and maintain the stability of the pressure inside the airbag 55, which can increase the overall sealing of the waterproof cutting lamp 3 and prevent the waterproof cutting lamp 3 from having an unstable seal when in use. In addition, the excess gas can be discharged during the sealing process of the waterproof cutting lamp 3 to prevent the sealing gasket 513 from being squeezed too deeply and damaged due to excessive pressure.

[0042] When the pressure inside the airbag 55 decreases due to temperature changes, the air pump 51 will start and transport the gas to the inside of the assembly tube 56 through the connecting tube 52, and then the assembly tube 56 will fill the gas into the airbag 55 to replenish the gas inside the airbag 55 and increase the pressure. The pressurized airbag 55 applies pressure to the sealing gasket 513 through the extrusion plate 510, so that it fits more tightly in the sealing groove 8, further enhancing the sealing effect, ensuring the stable operation and good performance of the waterproof beam lamp in various environments, and through the dynamic adjustment capability, the waterproof cutting lamp 3 can still maintain good sealing in a low temperature environment, preventing the waterproof cutting lamp 3 from scaling due to gas in a low temperature environment, thereby causing the overall sealing effect of the waterproof cutting lamp 3 to be poor, further increasing the scope of application of the waterproof cutting lamp 3.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
