[0002] General stage lamp includes the light head of built-in light source for projecting light beam and the arm for supporting the rotation of light head, will also set up the self-rotating effect disc for movable to selectively intercept light beam in light head. Figure 1 、 Figure 2 Its through rotation makes the light transmission hole enter light beam in turn to produce continuous dynamic pattern effect, for example, flame, running water, white cloud etc.

[0003] If the projection of the rotation axis of light head on the optical axis of light beam on effect disc is transverse axis, with the axis of effect disc through the intersection of transverse axis and optical axis and perpendicular to both as longitudinal axis, generally, the rotation center of effect disc will be located on transverse axis or longitudinal axis, so according to the installation angle of conventional stage lamp, when the light transmission hole passes through optical axis, the pattern disc projected by light transmission hole is horizontal or vertical state, looks more beautiful.

[0004] But stage lamp actual design, can not be arranged to transverse axis or longitudinal axis because of the compact space structure inside light head, lead to the pattern projected by light transmission hole is non-horizontal or non-vertical state (such as Figure 3 ), and other stage lamps look out of place. UTILITY MODEL CONTENT

[0005] The utility model provides a stage lamp of effect disc oblique setting to overcome at least one of the defects of the prior art, realize that even if effect disc oblique setting, light transmission hole projection can also realize horizontal or vertical state.

[0006] To solve the above technical problems, the utility model adopts the technical scheme: a stage lamp with effect disc oblique arrangement, including the lamp head of built -in light source for projecting light beam and the arm for supporting the rotation of lamp head, the effect disc that is not transparent is arranged in the lamp head and can rotate and move, a plurality of long strip light transmission holes are arranged on the effect disc, the effect disc has the first position of not interfering with the light beam and the second position of the light transmission hole and the light beam interference and produces continuous dynamic pattern effect by moving, the projection of the rotation axis of lamp head on the light axis of light beam is the horizontal axis on the effect disc, the axis that passes through the intersection of horizontal axis and light axis and is perpendicular to both of them on the effect disc is the vertical axis, when the effect disc is in the second position, the rotation center of effect disc is located between the horizontal axis and the vertical axis, the rotation center of effect disc is the center of circle, the vertical distance L between the rotation center of effect disc and the horizontal axis / the vertical axis at this time is the radius, the long strip light transmission hole extends along the tangent direction of the circle.

[0007] When the effect disc is in the second position, the rotation center of effect disc is located between the horizontal axis and the vertical axis (oblique arrangement), instead of being located on the horizontal axis and the vertical axis, by also obliquely arranging the light transmission hole with the corresponding angle, that is, taking the rotation center of effect disc as the center of circle, the vertical distance L between the rotation center of effect disc and the horizontal axis / the vertical axis at the time when the effect disc is in the second position is the radius, the long strip light transmission hole extends along the tangent direction of the circle, the light transmission hole can project the pattern in horizontal or vertical state when the light transmission hole passes through the light axis under the conventional installation angle of stage lamp, which looks more beautiful, so that the space in the lamp head can be reasonably utilized, and the light spot can still look the same as the conventional one.

[0008] Further, the effect disc switches between the first position and the second position in a swinging manner. The swinging driving structure corresponding to the swinging manner occupies a small space position, and the activity range of the effect disc is also small, thereby effectively saving the space in the lamp head.

Further enough space is left on both sides of the horizontal axis / the vertical axis to install other effect components.

[0011] Further, the distance between the rotation center of the effect disc and the vertical line of the optical axis is greater than the sum of the projection radius of the light beam on the effect disc and L. The circle with the rotation center of the effect disc as the center and L as the radius is always located outside the light beam, so that the light path is not affected.

[0012] Further, 1cm≤L≤4cm. L≥1cm provides space for the connection between the effect disc and the self-rotation driving mechanism, and L≤4cm can realize the miniaturization of the effect disc, so that the effect disc does not need to be set to be too large to completely cover the light beam by the area provided with the light transmission hole.

[0013] Further, the effect disc is located on the focal plane of the light source, so that the imaging of the light transmission hole is realized.

DETAILED DESCRIPTION

[0026] The drawings are only for example illustration, and can not be understood as the limitation of the patent; in order to better illustrate the embodiment, some components of the drawings can be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, some well-known structures and their description in the drawings can be omitted, which is understandable. The position relationship described in the drawings is only for example illustration, and can not be understood as the limitation of the patent.

[0027] As Figures 4 to 7 , the utility model provides a stage lamp of effect plate oblique, including built -in light source 110 for projecting light beam's lamp holder 100 and be used for supporting the rotation of lamp holder 100 arm 200, the lamp holder 100 inside is provided with the light -proof effect plate 400 that can rotate and move, be provided with a plurality of long strip shape's light transmittance hole 410 on effect plate 400, effect plate 400 has the first position (at this time effect plate 400 will not enter the light path) and the second position (at this time effect plate 400 rotates, and long strip shape light transmittance hole 410 sequentially enters the light beam) that the light transmittance hole 410 and light beam interference produce continuous dynamic pattern effect by moving with light beam mutual interference, with the rotation axis 120 of lamp holder 100 along the optical axis C of light beam in the projection of effect plate 400 as horizontal axis A, with the intersection of horizontal axis A and optical axis C and the vertical shaft of both on effect plate 400 as vertical axis B, when effect plate 400 is at second position, the rotation center 420 of effect plate 400 is located between horizontal axis A and vertical axis B (namely not on horizontal axis A or vertical axis B), with the rotation center 420 of effect plate 400 as the center, with the vertical distance L of rotation center 420 of effect plate 400 and horizontal axis A (such as Figure 6 ) / vertical axis B (such as Figure 7 ) at this time as radius, long strip shape light transmittance hole 410 extends along the tangent direction of the circle.

[0028] When the effect disk 400 is in the second position, and the rotation center 510 of the effect disk 400 is located between the horizontal axis A and the vertical axis B (obliquely positioned), rather than above the horizontal axis A and the vertical axis B, the light-transmitting hole 410 is also obliquely positioned at a corresponding angle. That is, with the rotation center 420 of the effect disk 400 as the center, and when the effect disk 400 is in the second position, the rotation center 420 of the effect disk 400 and the horizontal axis A (e.g., when the effect disk 400 is in the second position) are... Figure 6 With the vertical distance L as the radius, the elongated light-transmitting hole 410 extends along the tangent of this circle. This allows the light-transmitting hole 410 to project a horizontal pattern when it passes the optical axis C at a conventional stage light installation angle. Alternatively, with the rotation center 420 of the effect disk 400 as the center, and when the effect disk 400 is in the second position, the rotation center 420 of the effect disk 400 and the vertical axis B (e.g., when the effect disk 400 is in the second position) are perpendicular to each other. Figure 7 With the vertical distance L as the radius, the elongated light-transmitting hole 410 extends along the tangent of the circle. This allows the light-transmitting hole 410 to project a vertical pattern when it passes through the optical axis C at a conventional stage light installation angle, making it look more aesthetically pleasing. This ensures that the light spot looks the same as usual while making reasonable use of the space within the lamp head 100.

[0029] It should be noted that the elongated light-transmitting hole 410 extending along the tangent direction of the circle means that a single light-transmitting hole 410 generally extends along the tangent direction of the circle (i.e., the length direction of the light-transmitting hole 410 extends along the tangent direction of the circle), or multiple light-transmitting holes 410 are arranged sequentially along the tangent direction of the circle. However, a single light-transmitting hole 410 or its part may be curved or have an indistinct length direction.

[0030] In a preferred embodiment of this invention, the effect disc 400 switches between the first position and the second position by oscillation. The oscillation drive structure corresponding to the oscillation mode occupies a small space, and the range of motion of the effect disc 400 is also small, effectively saving space within the lamp head 100.

[0031] In this embodiment, the effect disk 400 is pivotally connected to the swing arm 600 and rotates through a self-rotation drive mechanism; the swing arm 600 is pivotally connected to the mounting plate 700 and swings through a swing drive structure, thereby moving the effect disk 400 between the first position and the second position. This is conventional technology in the field and will not be described in detail here.

[0032] In the preferred embodiment of the utility model, when the effect disc 400 is in the second position, the angle between the vertical line of the optical axis C passing through the rotation center 420 of the effect disc 400 and the horizontal axis A / vertical axis B ranges from 10° to 45°. Enough space is left on both sides of the horizontal axis A / vertical axis B to install other effect components. When the angle α between the vertical line of the optical axis C passing through the rotation center 420 of the effect disc 400 and the horizontal axis A is greater than 45°, it can be considered that the rotation center 420 of the effect disc 400 is closer to the vertical axis B, and the angle β between the vertical line of the optical axis C passing through the rotation center 420 of the effect disc 400 and the vertical axis B is used to represent.

[0033] In the preferred embodiment of the utility model, when the effect disc 400 is in the second position, the angle between the vertical line of the optical axis C passing through the rotation center 420 of the effect disc 400 and the horizontal axis A / vertical axis B ranges from 20° to 35°. Further, enough space is left on both sides of the horizontal axis A / vertical axis B to install other effect components.

[0034] Preferably, when the effect disc 400 is in the second position, the angle between the vertical line of the optical axis C passing through the rotation center 420 of the effect disc 400 and the horizontal axis A / vertical axis B ranges from about 30°.

[0035] In the preferred embodiment of the utility model, the distance H between the rotation center 420 of the effect disc 400 and the vertical line of the optical axis C is greater than the sum of the projection radii R and L of the light beam on the effect disc 400. It is ensured that the circle with the rotation center 420 of the effect disc 400 as the center and L as the radius is always located outside the light beam, avoiding affecting the light path.

[0036] Preferably, the distance H between the rotation center 420 of the effect disc 400 and the vertical line of the optical axis C is within 5mm of the difference between the sum of the projection radii R and L of the light beam on the effect disc 400, so as to control the area of the effect disc 400 to a reasonable size and avoid being too large.

[0037] In the preferred embodiment of the utility model, 1cm≤L≤4cm. L≥1cm leaves space for the connection between the effect disc 400 and its rotation driving mechanism, and L≤4cm can realize the miniaturization of the effect disc 400, avoiding the need to set the effect disc 400 too large to completely cover the light beam by setting the light-transmitting hole 410.

[0038] Preferably, L is about 2cm.

[0039] In the preferred embodiment of the utility model, the effect disc 400 is located at the focal plane of the light source 110, thereby realizing imaging of the light transmission hole 410. Of course, the effect disc 400 does not need to be located at the focal plane of the light source 110, and can be moved up and down appropriately, as long as it can realize imaging of the light transmission hole 410.

[0040] In the preferred embodiment of the utility model, the effect disc 400 is a metal disc, and the light transmission hole 410 is a hollow hole. The metal material is not easy to break. In other embodiments, the effect disc 400 can also be composed of a glass disc covered with a light shielding film having the light transmission hole 410.

[0041] In the preferred embodiment of the utility model, a pattern disc 500 for intercepting a light beam to project a specific pattern is further included, and the rotation center 510 of the pattern disc 500 is located at the horizontal axis A / the vertical axis B. The pattern piece 520 on the pattern disc 500 only allows the light beam to pass through the pattern area thereon, thereby projecting a specific pattern. Generally, the pattern disc 500 and the effect disc 400 do not interfere with the light beam at the same time. Generally, the pattern disc 500 is also located near the focal plane of the light source 110, so as to image, and the pattern disc 500 switches different pattern pieces 520 into the light beam by rotation.

[0042] The pattern piece 520 and the pattern disc 500 can be integrated (at this time, the pattern piece 520 cannot rotate by itself), or can be separated (at this time, the pattern piece 520 can rotate by itself, or can not rotate by itself). When the pattern piece 520 rotates by itself, the projected pattern will correspondingly rotate.

[0043] In the embodiment, the pattern piece 520 is pivoted to the pattern disc 500 through a rotating seat, thereby realizing self-rotation.

[0044] In the preferred embodiment of the utility model, the stage lamp further includes a machine case 300 for supporting rotation of the arm 200, thereby realizing rotation of the lamp head 100 in two dimensions, and projecting a light beam to any direction.

For ordinary skilled persons in the art, other different forms of changes or modifications can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model claims.
