Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to a stage lighting fixture and its dustproof structure. Background Technology

[0002] Stage lighting fixtures are one of the main lighting equipment in the performing arts industry, widely used in stage lighting, landscape lighting, and other fields. Depending on the application, they can generally be divided into outdoor and indoor lighting fixtures. Outdoor stage lighting fixtures typically need to be rainproof / waterproof and dustproof, while indoor stage lighting fixtures have relatively lower requirements for rainproof / waterproof and dustproof properties.

[0003] Whether it's outdoor or indoor stage lighting, heat dissipation is crucial, and specialized heat dissipation structures are typically incorporated into the lighting fixture's design. However, while addressing heat dissipation, traditional stage lighting often neglects dust prevention. As a result, after prolonged use, the delicate optical components (such as lenses and light sources) easily accumulate dust, affecting the lighting's luminous efficacy.

[0004] For example, Chinese utility model patent CN209229695U, published on August 9, 2019, discloses a heat dissipation structure for a waterproof moving head light bulb. It uses exhaust fans installed on both sides of the lamp body to achieve air circulation and dissipate heat from the bulb inside. However, because the lamp body is a single, hollow cavity with the bulb located inside, external dust is drawn into the cavity during the fan cooling process, contaminating the bulb and other optical components and affecting the light-emitting effect of the lamp. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a stage lighting fixture and its dustproof structure to solve the dustproof problem of the stage lighting fixture during the heat dissipation process.

[0007] Furthermore, the first heat dissipation window is located on both sides of the lamp housing of the heat dissipation cavity, and a cooling fan is installed correspondingly inside the heat dissipation cavity on the inner side of the first heat dissipation window. One side of the cooling fan is an intake fan, and the other side is an exhaust fan, forming a horizontal airflow.

[0008] Further, in order to increase the sealing effect and dustproof effect, the partition plate is sealingly connected with the light source mounting plate. Alternatively, the partition plate and the light source mounting plate are integrated. Further, the light source mounting plate is provided with a mounting hole for the light source assembly, and the light emitting surface of the light source assembly passes through the mounting hole and is located in the light emitting assembly cavity, so that the light emitting assembly cavity where the light source assembly is located is completely isolated from the heat dissipation cavity.

[0009] Further, the light emitting assembly cavity is located at the upper part of the heat dissipation cavity.

[0010] Based on the dustproof structure of the stage lamp, the utility model also provides a stage lamp, which comprises a lamp body and a base, the lamp body is installed on the base through a rotating arm, and the lamp body comprises any one of the dustproof structures.

[0011] Further, the lamp body is rotatably connected with the rotating arm through a first rotating shaft at both sides, the base is provided with a second rotating shaft rotatably connected with the rotating arm, and the rotating arm is in a U-shaped structure. The base is also provided with control buttons, a display screen, an interface and a second heat dissipation window for controlling the stage lamp.

Specifically, the two sides of the lamp body 100 are rotatably connected with the rotary arm 35 through a first rotary shaft 16, and the base 30 is rotatably connected with the rotary arm 35 through a second rotary shaft 36, and the rotary arm 35 is in a U-shaped structure, and the lamp body 100 is placed in the U-shaped bracket structure.

The partition plate 12 and the inner wall of the lamp shell 11 can be integrally formed, or can be fixedly connected or bonded by a sealing rubber ring (not shown).

[0023] The light emitting assembly cavity 10 is located at the upper portion of the heat dissipation cavity 20, and the light emitting assembly cavity 10 and the heat dissipation cavity 20 are completely sealed and isolated by the partition plate 12. A light source mounting plate 14 on which a light source assembly 13 is mounted is arranged at the middle portion of the partition plate 12, the light emitting surface of the light source assembly 13 faces one side of the light emitting assembly cavity 10, and a heat dissipation assembly 21 is arranged at the bottom of the light source mounting plate 14; the heat dissipation assembly 21 (such as a heat dissipation fin) is arranged in the heat dissipation cavity 20, a first heat dissipation window 23 is arranged on the corresponding side wall of the lamp shell of the heat dissipation cavity 20, and a heat dissipation fan 22 is further arranged between the heat dissipation assembly 21 and the first heat dissipation window 23.
