Description

Technical Field

[0001] The utility model relates to the field of stage lights, and more particularly to a stage spotlight. Background Art

[0002] Stage spotlights refer to lamps used to produce cylindrical light effects on the stage. They are generally used to focus on improving the brightness of a certain part of the stage to highlight that location. They are a common type of stage lights. Generally, the power of stage spotlights is relatively large, so the light-emitting end of the stage spotlights easily generates heat, which is difficult to dissipate in time, resulting in a substantial temperature rise. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a stage spotlight.

[0004] The above technical objectives of the present utility model are achieved through the following technical solutions: a stage spotlight, comprising a lamp tube, a receiving groove is provided at one end of the lamp tube, a plurality of lamp bodies are provided in the receiving groove, a fan is provided at the other end of the lamp tube, a plurality of ventilation grooves connected to the receiving groove are provided on the lamp tube, the ventilation grooves are arranged in a circular array along the edge of the receiving groove, and the ventilation grooves run through the lamp tube.

[0005] The utility model is further configured as follows: the opening of the accommodating groove is covered with a light-transmitting plate, a plurality of ventilation holes are arranged in a circumferential array on the light-transmitting plate, and the distance between the ventilation holes and the axis of the light-transmitting plate is smaller than the distance between the ventilation groove and the axis of the light-transmitting plate.

[0006] The utility model is further configured as follows: an annular groove is opened on the side wall of the accommodating groove, and the annular groove is communicated with the ventilation groove.

[0007] The utility model is further configured such that: the light-transmitting plate is detachably connected to the lamp tube.

[0008] The utility model is further configured as follows: the lamp tube comprises a shell and a side cover detachably connected to the side wall of the shell, and the ventilation slot is located between the side cover and the shell.

[0009] The utility model is further configured as follows: a cover is provided on a side of the fan away from the lamp tube.

[0010] In summary, the present invention has the following beneficial effects: air carries heat and moves in the direction from the accommodating cavity to the fan, thereby improving the heat dissipation performance of the stage spotlight, slowing down the heating rate of the stage spotlight, and limiting the position where outside air enters the accommodating cavity through the vents, thereby ensuring that a certain intensity of air flow can be maintained around the lamp body located in the center of the accommodating cavity.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] Embodiment: A stage spotlight, such as Figure 1 、 Figure 2 As shown, it includes a lamp tube, a receiving groove 1 is provided at one end of the lamp tube, a plurality of lamp bodies 2 are provided in the receiving groove 1, a fan 3 is provided at the other end of the lamp tube, a plurality of ventilation grooves 4 connected to the receiving groove 1 are provided on the lamp tube, the ventilation grooves 4 are arranged in a circular array along the edge of the receiving groove 1, the ventilation grooves 4 pass through the lamp tube, and a cover 9 is provided on the side of the fan 3 away from the lamp tube.

[0016] Specifically, in this embodiment, there are seven lamp bodies 2 in the receiving groove 1, and two ventilation grooves 4 are distributed on both sides of the lamp tube. The fan 3 draws out the air in the receiving cavity through the ventilation grooves 4. The air carries heat and moves in the direction from the receiving cavity to the fan 3, thereby improving the heat dissipation performance of the stage spotlight and slowing down the heating rate of the stage spotlight. The cover 9 covers the fan 3 to prevent the fan 3 from colliding with the outside world, thereby extending the service life of the fan 3.

[0017] like Figure 1 、 Figure 2 As shown, the opening of the accommodating groove 1 is covered with a light-transmitting plate 5, and a plurality of ventilation holes 10 are arranged in a circular array on the light-transmitting plate 5. The distance between the ventilation holes 10 and the axis of the light-transmitting plate 5 is smaller than the distance between the ventilation groove 4 and the axis of the light-transmitting plate 5. An annular groove 6 is provided on the side wall of the accommodating groove 1, and the annular groove 6 is connected to the ventilation groove 4. The light-transmitting plate 5 is detachably connected to the lamp tube.

[0018] Specifically, the light-transmitting plate 5 is made of a transparent material, and eight vents 10 all pass through the light-transmitting plate 5. The vents 10 limit the position of outside air entering the accommodating cavity, ensuring that a certain intensity of air flow can be maintained around the lamp body 2 located at the center of the accommodating cavity. The airflow moves from the center of the accommodating cavity to the ventilation groove 4 at the edge of the accommodating cavity. The annular groove 6 increases the air flow between the outer circle lamp bodies 2, ensuring the uniformity of heat dissipation. The light-transmitting plate 5 is detachably connected to the lamp tube by bolts. The detachable light-transmitting plate 5 facilitates the cleaning of the accommodating cavity to prevent dust from affecting heat dissipation.

[0019] like Figure 1 、 Figure 2As shown, the lamp tube includes a shell 7 and a side cover 8 detachably connected to the side wall of the shell 7. The ventilation slot 4 is located between the side cover 8 and the shell 7. The side cover 8 is an arched structure. By removing the side cover 8, the ventilation slot 4 is exposed, which facilitates the cleaning of the ventilation slot 4 and avoids the accumulation of the annular groove 6, which leads to a reduction in the flow area of ​​the ventilation slot 4.

[0020] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
