Description

Technical Field

[0001] The present invention relates to the technical field of stage lighting, and particularly to a stage light with a quickly replaceable drying device. Background Art

[0002] Stage lights are lighting and lighting effect devices commonly used on stages. In actual applications, in order to prevent water from entering the interior of the stage light and avoid damage to the electrical components inside the stage light, a dehumidification module is generally provided in the passage of the breathing valve. The reason is that the breathing valve can prevent water droplets but not water vapor from entering the lamp body. Specifically, the dehumidification module includes an installation box and a water-absorbing filler installed in the installation box, so that the external moisture enters the lamp body after being dried. However, the installation box is fixed inside the lamp body, and the water-absorbing filler needs to be replaced regularly after being saturated with water. When replacing, the lamp body shell needs to be disassembled, so the replacement steps are particularly cumbersome, time-consuming and laborious.

[0003] Therefore, there is an urgent need for a technical solution for a stage light with a quickly replaceable drying device. Summary of the Invention

[0004] The present invention provides a stage light with a quickly replaceable drying device to solve one of the above technical problems, which can replace the desiccant without disassembling the lamp shell, and the replacement is convenient and fast.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A stage light with a quickly replaceable drying device includes a lamp housing. A box body integrally formed with the lamp housing is arranged inside the lamp housing. The box body has a receiving cavity. Through holes are formed in the side wall of the receiving cavity and the receiving cavity is communicated with the inside of the lamp housing through the through holes. An opening communicating with the outside is formed on the lamp housing, and the receiving cavity is communicated with the outside through the opening. A drying member is arranged in the receiving cavity. A cover plate covering the opening is detachably connected to the lamp housing. The cover plate is hermetically connected to the lamp housing through a sealing structure. A communication port for communicating the receiving cavity with the outside is formed on the cover plate, and a breathing valve is hermetically connected to the communication port.

[0007] As a preferred embodiment, it is further defined that the lamp housing is provided with a groove around the outside of the opening, and the cover plate is adaptively installed in the groove and connected to the lamp housing through a fastener.

[0008] As a preferred embodiment, it is further defined that the sealing structure includes a waterproof groove formed at the bottom of the groove and around the outside of the opening and a waterproof ring accommodated in the groove. The cover plate is in sealing contact with the lamp housing through the waterproof ring.

[0009] As a preferred embodiment, it is further defined that annular protrusions are provided on both the outer circumferential surface and the inner circumferential surface of the waterproof ring, and the waterproof ring is in sealing contact with the side wall of the waterproof groove through the annular protrusions.

[0010] As a preferred embodiment, it is further defined that the two side surfaces of the waterproof groove in the width direction are respectively flush with the two side surfaces of the groove in the width direction one by one.

[0011] As a preferred embodiment, it is further defined that the drying member includes a storage box and a desiccant stored in the storage box.

[0012] As a preferred embodiment, it is further defined that the desiccant is molecular sieve.

[0013] After adopting the above technical solution, the present invention has at least the following beneficial effects: when the external humid air enters the accommodation cavity after passing through the breathing valve, the humid air will be absorbed by the drying member, and the obtained dry air will diffuse into the interior of the lamp housing through the through holes. Therefore, while maintaining the air pressure balance inside and outside the lamp housing, the interior can be kept dry, thus avoiding damage to electrical components; during replacement, first remove the cover plate, then take out the drying member in the accommodation cavity for replacement, and finally fix the cover plate to complete the replacement. The replacement of the drying member does not require disassembling and assembling the lamp housing, thus avoiding excessive and cumbersome disassembly and assembly steps and greatly improving the replacement efficiency.

[0018] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will further describe the present application in detail with reference to the drawings and specific embodiments.

[0019] As shown in the attached Figure 1 to the attached Figure 3As shown in the figure, a stage light with a quickly replaceable drying device includes a lamp housing 1. A box body 2 integrally formed with the lamp housing 1 is arranged inside the lamp housing 1. The box body 2 has a receiving cavity 20. A through hole 201 is provided through the side wall of the receiving cavity 20. The receiving cavity 20 communicates with the inside of the lamp housing 1 through the through hole 201. An opening 10 communicating with the outside is provided on the lamp housing 1. The receiving cavity 20 communicates with the outside through the opening 10. A drying member 3 is arranged in the receiving cavity 20. The lamp housing 1 is detachably connected with a cover plate 4 that shields the opening 10. The cover plate 4 is hermetically connected with the lamp housing 1 through a sealing structure. A communication port 41 for the receiving cavity 20 to communicate with the outside is provided on the cover plate 4. A breathing valve 5 is hermetically connected to the communication port 41.

[0020] Further, when the external humid air enters the receiving cavity 20 after passing through the breathing valve 5, the humid air will be absorbed by the drying member 3 for moisture, and the obtained dry air will diffuse into the inside of the lamp housing 1 through the through hole. Therefore, while maintaining the air pressure balance inside and outside the lamp housing, a dry environment can be maintained inside it, thereby avoiding damage to electrical components.

[0021] During replacement, first remove the cover plate 4, then take out the drying member 3 in the receiving cavity 20 for replacement, and finally fix the cover plate 4 to complete the replacement. The replacement of the drying member does not require disassembling and assembling the lamp housing, thus avoiding excessive and cumbersome disassembly and assembly steps and greatly improving the replacement efficiency.

[0022] In this embodiment, the lamp housing 1 is provided with a groove 11 around the outside of the opening 10. The cover plate 4 is adaptively installed in the groove 11 and connected to the lamp housing 1 through a fastener 6. The fastener 6 is a screw to facilitate the disassembly or fixing of the cover plate 4.

[0023] In this embodiment, the sealing structure includes a waterproof groove 12 opened at the bottom of the groove 11 and around the outside of the opening 10 and a waterproof ring 7 accommodated in the groove 11. The cover plate 4 is in sealing contact with the lamp housing 1 through the waterproof ring 7, thereby enhancing the airtightness between the cover plate 4 and the lamp housing 1.

[0024] As shown in the appendix Figure 4 As shown in the figure, annular protrusions 71 are provided on both the outer circumferential surface and the inner circumferential surface of the waterproof ring 7. The waterproof ring 7 is in sealing contact with the side wall of the waterproof groove 12 through the annular protrusions 71. The annular protrusions 71 are beneficial for the waterproof ring 7 to fully contact the waterproof groove 12, further increasing the airtightness inside the lamp housing.

[0025] In this embodiment, the two side surfaces of the waterproof groove 12 in the width direction are respectively flush with the two side surfaces of the groove 11 in the width direction one by one, making the appearance of the lamp housing more compact and not obtrusive.

[0026] In this embodiment, the drying member 3 includes a storage box and a desiccant stored in the storage box, which facilitates the overall replacement of the desiccant and improves the replacement efficiency. The desiccant is a molecular sieve, that is, a silicon-aluminum salt microporous crystal. Compared with other desiccants, the molecular sieve has the characteristics of uniform pore size, extremely high specific surface area, good thermal stability, strong adsorption performance, large internal surface area, high strength, etc.; further, it has strong water absorption. Even under the conditions of high temperature, large space velocity and low water content where the reduction condition of the molecular sieve is to be baked at 200 °C for 2 hours, but the temperature inside the lamp body is far from reaching this, it still has a quite high water absorption capacity.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various equivalent changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalent scope.
