Description

Technical Field

[0001] The utility model belongs to the technical field of stage lights, and particularly relates to an LED stage effect light with two lamp heads. Background Technique

[0002] With the progress of technology and the enhancement of environmental awareness, LED light sources, with their significant advantages of high efficiency, low energy consumption, environmental friendliness, flexible color control, long service life, and high safety, have become an indispensable core component of stage lighting. In recent years, the design of stage lights has been developing rapidly towards miniaturization, intelligence, and multi-functional integration. Most of the existing stage lights are equipped with a single lamp head, and when outputting light, only a single light path can be formed, making the stage effect appear relatively monotonous and unable to meet the diverse requirements of modern stage art for lighting effects.

[0003] In order to present a rich and colorful stage effect, the prior art sets the stage light to include two lamp heads. For example, in the prior art, the Chinese patent document with the publication number CN202469621U discloses a two-lamp-head moving head light. This two-lamp-head moving head light includes a base, a U-shaped frame fixedly installed on the base, and a support plate vertically extending and fixed inside the U-shaped frame. A lamp head is installed on each side of the support plate. A rotating main shaft extending from both sides is installed on the lamp head. One end of the rotating main shaft is pivotally connected to the support plate, and the other end is pivotally connected to the side wall of the corresponding U-shaped frame. The two rotating main shafts are respectively driven by two motors installed on the base or the U-shaped frame.

[0004] Although when the above two-lamp-head moving head light is in use, the two lamp heads can rotate in the same or opposite directions and output diverse light and shadow effects, the above two-lamp-head moving head light has a relatively large volume and has a bulky U-shaped frame and base, making manual handling very time-consuming and laborious, which is not conducive to the miniaturization and lightweight of stage lights.

[0005] Therefore, there is an urgent need for an LED stage effect light with two lamp heads that is smaller in volume, more compact in structure, and has a more colorful lighting effect. Summary of the Invention

[0059] Specifically, the absolute value of the angle range of the reciprocating swing of each lamp head in the vertical direction is 60°-70°;

[0070] Specifically, the lamp body front cover group includes two cover bodies 5, and a hollowed-out lamp hole 51 is provided on the surface of each cover body 5. One side of each lamp head where light exits protrudes from the corresponding lamp hole 51, and each lamp hole 51 communicates with the lamp cavity 16;

[0071] It should be noted that the lamp body front cover group can be provided with only one long cover, and the long cover is equivalent to the combination of two cover bodies 5; at the same time, two lamp holes 51 are provided on one long cover, which has the same effect as providing the lamp holes 51 on two cover bodies 5 respectively.

[0072] As Figures 6-7 shown, the longitudinal diameter of each lamp hole 51 is greater than the diameter of each lamp head, so that each lamp head can swing up and down in the corresponding lamp hole 51. This design significantly enhances the flexibility and adjustability of the lamp body 1, and users can easily adjust the angle of the lamp head according to actual needs or lighting effects.

[0073] As Figures 3-4As shown, the front side of the outer shell 21 is arranged on the same side as the light-emitting side of each lamp head, and the rear side of the outer shell 21 is fixedly connected to the inner wall of the rear side of the outer frame 11; the partition base 2 includes a first fixing plate 27 and a second fixing plate 28 which are symmetrically arranged up and down; the outer shell 21 is respectively connected to the upper and lower ends of the outer frame 11 through the first fixing plate 27 and the second fixing plate 28;

[0087] As Figures 6-7 shown, the usage process of an LED stage effect lamp with a double lamp head according to this embodiment is as follows:

[0088] When both the first lamp holder 12 and the second lamp holder 13 swing upward, the rotating shaft of the first driving motor 22 rotates counterclockwise, and the rotating shaft of the second driving motor 23 rotates clockwise. The rotating shaft of the first driving motor 22 drives the first transmission belt 25 to move. The first transmission gear 24 rotates along with the first transmission belt 25 and drives the corresponding main rotating shaft 41 to rotate. The main rotating shaft 41 drives the first lamp holder 12 to rotate. Meanwhile, the rotating shaft of the second driving motor 23 drives the second transmission belt 25 to move. The second transmission gear 24 rotates along with the second transmission belt 25 and drives the corresponding main rotating shaft 41 to rotate.
