Problems solved by technology

However, in the existing technology, the adjustment range of the adjustment device for the position of the bulb is generally too large to achieve fine adjustment, and the adjustment positioning is not accurate, and the adjustment accuracy is not high. Usually, it is necessary to repeat the adjustment steps many times, and the operation is cumbersome and time-consuming. The fine-tuning effect of the
Moreover, the direction of adjustment is also limited, and in some directions there is no way to adjust

Embodiment 1

[0028] refer to Figure 1-2 , the light bulb adjustment device of the stage lamp according to the present invention comprises a fixed plate 2 with a first center hole, an adjustment plate 3, a radial adjustment mechanism, a front and rear adjustment mechanism, a bulb clamping device and a spherical surface with a second center hole The orientation piece 4, the bulb 1 is installed on the bulb clamping device, the fixed plate 2 is fixedly connected with the stage lamp body (not shown in the figure), the bulb clamping device is fixedly installed on the adjustment plate 3, the bulb clamping device Connected with the front and rear adjustment mechanism, the fixed plate 2 and the adjustment plate 3 are connected through a radial adjustment mechanism, and the spherical orientation member 4 is arranged between the fixed plate 2 and the adjustment plate 3 and is fixedly connected to the adjustment plate 3 . The convex surface of the spherical directional element 4 is in contact with th...

Embodiment 2

[0052] Such as Figure 4 and Figure 5 As shown, at least a part of the central hole of the fixing plate 2 is a spherical surface 21 , and the spherical surface 21 forms a spherical surface contact with the spherical surface portion of the spherical surface orientation member 4 . The spherical surface of the spherical directional element 4 cooperates with the spherical surface of the fixed plate 2 to form a spherical hinge, so the spherical directional element 4 can rotate, and its axis can form any angle with the surface of the fixed plate 2 within a certain range. Since the adjustment plate 3 and the spherical orientation member 4 are fixedly connected together, the angle between the adjustment plate 3 and the fixed plate 2 can be controlled by adjusting the radial adjustment mechanism to control the distance between the axis of the spherical orientation member 4 and the surface of the fixed plate 2. Angle, and then realize the function of fine-tuning the position of the li...

Abstract

The invention discloses an adjusting device for conveniently adjusting a lamp bulb of a stage lamp. The lamp bulb adjusting device comprises a fixed plate, an adjusting plate, a radial adjusting mechanism, a front and back adjusting mechanism, a lamp bulb clamping device and a spherical orienting piece, wherein the fixing plate is provided with a first central hole; the fixed plate is fixedly connected to the lamp body of the stage lamp; the lamp bulb clamping device is fixedly arranged on the adjusting plate; the lamp bulb clamping device is connected with the front and back adjusting mechanism; the fixed plate and the adjusting plate are connected with each other through the radial adjusting mechanism; the spherical orienting piece is provided with a second central hole, and is fixedly connected to the adjusting plate; the convex surface of the spherical orienting piece is contacted with the first central hole of the fixing plate; the spherical surface of the spherical orienting piece is matched with the fixed plate to form a spherical hinge structure; the spherical orienting piece is rotatable; the axis of the spherical orienting piece can form any angle with the surface of the fixed plate in a certain range. The adjusting plate is fixedly connected together with the spherical orienting piece, and an angle formed between the adjusting plate and the fixed plate is controlled by adjusting the radial adjusting mechanism, so that the angle between the axis of the spherical orienting piece and the surface of the fixed plate is controlled, and the position of the lamp bulb is finely and accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of stage lamps, in particular to an adjusting device for conveniently adjusting bulbs of stage lamps. Background technique [0002] Existing high-power follow-spot lights generally use xenon bulbs as light sources, and the fixing method of the bulbs is usually realized by two fixing parts clamping the two electrode ends of the bulbs respectively. In actual use, due to assembly errors and other reasons, it is often necessary to adjust the position of the bulb to ensure that the luminous point of the bulb is on the central axis of the lamp. However, in the existing technology, the adjustment range of the adjustment device for the position of the light bulb is generally too large to achieve fine adjustment. Moreover, the adjustment positioning is not accurate, and the adjustment accuracy is not high. Usually, it is necessary to repeat the adjustment steps many times, and the operation is cumbersome and time-con...
