AI Technical Summary
When adjusting the angle, existing lighting fixtures cannot ensure that the uplift angle of each lamp is the same, resulting in uneven brightness on the front side of the stage, which easily produces light deviations, affecting the audience's viewing effect.
A lighting fixture including a mounting frame, a lighting body, an adjustment plate and a cam press rod are designed. By providing an adjustment plate on the rear side of the lighting body and using the cooperation of the cam pressing rod and the spring, the lighting angle of the multiple lighting bodies is synchronously adjusted.
The lighting angle is adjusted simultaneously by multiple lighting bodies, ensuring the brightness uniformity on the front side of the stage, reducing lighting deviations, and improving the viewing effect of the audience.

Description
Technical Field
[0001] The utility model relates to the technical field of lighting fixtures, and in particular to a lighting fixture with adjustable illumination angle. Background Art
[0002] Today's lighting fixtures are generally adjustable in angle, and can project light onto specific areas or objects to improve lighting and enhance the effect. These lamps include chandeliers, floor lamps, wall lamps, etc., each with its own unique characteristics and advantages.
[0003] When using lighting fixtures at the back of the stage, since the rear lighting fixtures are the main lighting fixtures, the rear lighting fixtures are responsible for illuminating the entire stage to the front, and most of the existing lighting fixtures can only be adjusted individually. When adjusting individually, it is impossible to ensure that the inclination angles of each lamp are the same, which affects the brightness uniformity of the front of the stage and easily creates a sense of lighting deviation, affecting the viewing effect of the audience.

[0012] Optionally, the clamping rod is correspondingly engaged in the inside of the clamping port, and connecting plates are fixed on both sides of the mounting frame.
[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:
[0014] 1. In the utility model, when using the device, the lighting lamp body is rotated and connected between the inner walls of the installation opening, and then a spring is arranged between the top of the lighting lamp body near the rear side and the bottom of the support plate, and at the same time, the adjustment plate and the cam pressure rod on the rear side of the lighting lamp body are fitted with each other, and under the elastic pressure of the spring, there is always a contact force between the adjustment plate and the cam pressure rod, and when the cam pressure rod is rotated, the adjustment plate can be pressed downward, thereby changing the angle of the lighting lamp body, so as to achieve the purpose of synchronously adjusting the illumination angle of multiple lighting lamp bodies.
[0015] 2. In the utility model, when rotating the cam pressure rod, it is first necessary to pull the adjusting knob toward the outside of the fixing sleeve until the clamping rod is separated from the inside of the clamping port, and then the adjusting knob can be turned to drive the cam pressure rod to rotate.

DETAILED DESCRIPTION
[0024] The utility model will now be further described in detail with reference to the accompanying drawings.
[0025] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution for a lighting fixture with adjustable lighting angle: it includes a mounting frame 1, a plurality of mounting openings 2 are equidistantly provided on the front side of the mounting frame 1, a lighting body 3 is rotatably connected between the inner walls on both sides of the plurality of mounting openings 2, an adjustment plate 7 is fixed to the rear sides of the plurality of lighting bodies 3, the tops of the plurality of adjustment plates 7 are all inclined, a cam pressure rod 6 is rotatably connected between the inner walls on both sides of the mounting frame 1, and the outer surface of the cam pressure rod 6 is in contact with the inclined surfaces on the tops of the plurality of adjustment plates 7.
[0026] The effect achieved by the entire embodiment 1 is that when using the device, the lighting lamp body 3 is rotated and connected between the inner walls of the installation opening 2, and then a spring 8 is arranged between the top of the lighting lamp body 3 near the rear side and the bottom of the support plate 5, and at the same time, the adjustment plate 7 and the cam pressure rod 6 on the rear side of the lighting lamp body 3 are fitted with each other. Under the elastic pressure of the spring 8, there is always a contact force between the adjustment plate 7 and the cam pressure rod 6. When the cam pressure rod 6 is rotated, the adjustment plate 7 can be pressed downward, thereby changing the angle of the lighting lamp body 3, so as to achieve the purpose of synchronously adjusting the lighting angles of multiple lighting lamp bodies 3.
[0027] Embodiment 2, as Figure 1-4As shown, a support plate 5 is fixed between the inner walls on both sides of the mounting frame 1 near the top edge, a plurality of springs 8 are fixed on the top of the lamp bodies 3, and the tops of the plurality of springs 8 are correspondingly fixed to the bottom of the support plate 5, a fixing sleeve 9 is installed on one side of the mounting frame 1, one end of the cam pressure rod 6 is cylindrical and extends to between the inner walls of the fixing sleeve 9, a cross groove 11 is provided at one end of the cam pressure rod 6, a cross block 13 is slidably engaged inside the cross groove 11, an adjusting knob 12 is fixed on the front side of the cross block 13, and clamping rods 14 are fixed to the outer surfaces of both sides of the adjusting knob 12, a plurality of bayonet holes 10 are equidistantly provided on the outer surface of the fixing sleeve 9 along the circumferential direction, and the clamping rods 14 are correspondingly engaged inside the bayonet holes 10, and connecting plates 4 are fixed on both sides of the mounting frame 1.
[0028] The effect achieved by the entire embodiment 2 is that when rotating the cam lever 6, it is first necessary to pull the adjusting knob 12 toward the outside of the fixing sleeve 9 until the clamping rod 14 is separated from the inside of the clamping socket 10, and then the adjusting knob 12 is rotated to drive the cam lever 6 to rotate. After the lighting lamp body 3 is adjusted to a suitable angle, the cross clamping block 13 is pressed to the bottom of the cross clamping groove 11, so that the clamping rod 14 is engaged with the inside of the clamping socket 10 to position the cam lever 6, thereby preventing the cam lever 6 from rotating to change the angle of the lighting lamp body 3 after the lighting lamp body 3 is adjusted to a suitable angle.
[0029] Working principle: When using the device, the lighting lamp body 3 is rotated and connected between the inner walls of the installation opening 2, and then a spring 8 is arranged between the top of the lighting lamp body 3 near the rear side and the bottom of the support plate 5, and at the same time, the adjustment plate 7 and the cam pressure rod 6 on the rear side of the lighting lamp body 3 are fitted with each other. Under the elastic pressure of the spring 8, the adjustment plate 7 always has a contact force with the cam pressure rod 6. When the cam pressure rod 6 is rotated, the adjustment plate 7 can be pressed downward, thereby changing the angle of the lighting lamp body 3, so as to achieve the goal of synchronously adjusting the light of multiple lighting lamp bodies 3. For the purpose of adjusting the angle, when rotating the cam lever 6, it is first necessary to pull the adjusting knob 12 toward the outside of the fixing sleeve 9 until the clamping rod 14 is separated from the inside of the clamping socket 10, and then the adjusting knob 12 is turned to drive the cam lever 6 to rotate. After the lighting lamp body 3 is adjusted to a suitable angle, the cross clamping block 13 is pressed to the bottom of the cross clamping groove 11, so that the clamping rod 14 is engaged with the inside of the clamping socket 10 to position the cam lever 6, thereby preventing the cam lever 6 from rotating to change the angle of the lighting lamp body 3 after the lighting lamp body 3 is adjusted to a suitable angle.
