Description

Technical Field

[0001] The utility model belongs to the field of stage lights, and in particular relates to a light source quick replacement and adjustment device for stage lights. Background Art

[0002] As a high-power LED lamp, stage lights have the advantages of high brightness and high color saturation, and are widely used in stage art performances. They are important lighting tools for stage art performances. However, most existing stage lights have a complex structure. When the bulb of the stage light needs to be replaced, a series of tools are needed to open the inside of the stage light and replace the bulb, which is inconvenient for later maintenance.

[0003] In the prior art, for example, the patent document with publication number CN209672277U discloses a stage lamp that can quickly install, replace and adjust the light source bulb. The back of the stage lamp is provided with a protective cover with a spring. When the bulb needs to be replaced, the quick-lock screw is unscrewed by a tool, and the protective cover pops open under the action of the spring, and then the bulb is replaced. However, the protective cover of the stage lamp requires a tool to open, and when the protective cover pops open, there is a risk that the quick-lock screw will be thrown out, resulting in the risk that the protective cover cannot be closed.

[0004] Therefore, there is an urgent need for a light source quick replacement and adjustment device for stage lights to solve the above problems. Summary of the invention

[0005] In view of the problems in the prior art, the utility model proposes a device for quickly replacing and adjusting light sources for stage lights. The light-emitting unit is fixed in a slot by rotating and snapping the light-emitting unit, thereby improving the convenience of replacing the light-emitting unit. At the same time, the light-emitting unit can be adjusted in any direction on a horizontal plane by adjusting the mounting plate and the adjustment plate, thereby improving the convenience of adjusting the light-emitting unit.

[0006] The utility model is implemented as follows: a light source quick replacement and adjustment device for stage lights, comprising a mounting bracket, an adjustment plate and a mounting plate arranged in sequence, the mounting plate is provided with a light source assembly, the light source assembly comprises a first clamping unit and a second clamping unit, the second clamping unit is arranged below the first clamping unit and elastically connected to the first clamping unit, and a card slot is further provided between the first clamping unit and the second clamping unit;

[0007] The light source assembly also includes a light-emitting unit, and the light-emitting unit is provided with a plurality of clamping parts in a circumferential direction. The first clamping unit is also provided with a mounting hole for the light-emitting unit to pass through. After the light-emitting unit passes through the mounting hole, the clamping part is clamped with the slot by a rotating action. When replacing the light-emitting unit, the clamping part can be disengaged from the slot by simply rotating it, and the old light-emitting unit can be removed. When installing a new light-emitting unit, the new light-emitting unit can be passed through the mounting hole from top to bottom and rotated, so that the clamping part can be clamped in the slot to complete the replacement. The operation is simple and quick, and the effect of quickly replacing the light-emitting unit is achieved.

[0008] The mounting bracket is slidably connected to the adjustment plate in a fixed manner, and the adjustment plate is slidably connected to the mounting plate in a fixed manner. Since each light-emitting unit cannot be exactly the same, there will inevitably be a certain error between the replaced light-emitting unit and the light-emitting unit before and after replacement, which will affect the lighting effect of the stage light. At this time, the position of the light-emitting unit can be adjusted through the adjustment plate and the mounting plate, so that the brightest point of the light spot or light beam projected by the light-emitting unit is at the center of the light spot or light beam, avoiding the light spot or light beam being eccentric in the light path of the lamp and affecting the lighting effect.

[0009] Preferably, the first clamping unit is further provided with an elastic component, one end of which is elastically connected to the first clamping unit and the other end is fixedly connected to the second clamping unit. The elastic component is used to reinforce the light-emitting unit to prevent the light-emitting unit from shaking, thereby affecting the lighting effect of the stage light.

[0010] Specifically, the elastic component includes a first elastic unit and a first screw, the first screw passes through the first clamping unit from top to bottom and is fixedly connected to the second clamping unit, the lower end of the first elastic unit abuts against the first clamping unit, and the upper end abuts against the head of the first screw. When installing the light-emitting unit, the light-emitting unit passes through the mounting hole from top to bottom and presses the second clamping unit downward to compress the first elastic unit, and at the same time rotates the light-emitting unit to engage it in the slot, and then releases the light-emitting unit. The second clamping unit clamps the light-emitting unit under the reaction force of the first elastic unit to prevent the light-emitting unit from shaking, thereby improving the reliability of the light-emitting unit.

[0011] Preferably, the mounting plate is provided with a plurality of first adjustment grooves, which extend along the long side direction or the short side direction of the mounting plate. The first adjustment grooves are used to adjust the relative position of the mounting plate and the adjustment plate, so that the mounting plate can only slide in one direction, thereby improving the convenience of adjusting the light-emitting unit.

[0012] Specifically, the adjustment plate is further provided with a plurality of second adjustment slots, and the extension direction of the second adjustment slots is perpendicular to the extension direction of the first adjustment slots. The second adjustment slots enable the adjustment plate to slide only in a direction perpendicular to the sliding direction of the mounting plate, thereby improving the convenience of adjusting the light-emitting unit. At the same time, the adjustment plate and the mounting plate cooperate with each other, so that the light-emitting unit can be adjusted in any direction on the horizontal plane, and the adjustment range of the light-emitting unit is also taken into account while ensuring the convenience of adjusting the light-emitting unit.

[0013] Specifically, the mounting plate is further provided with a first notch, a first eccentric unit is provided in the first notch, and the first eccentric unit abuts against the inner wall of the first notch; the adjustment plate is further provided with a second notch, a second eccentric unit is provided in the second notch, and the second eccentric unit abuts against the inner wall of the second notch. The first eccentric unit / second eccentric unit is used to adjust the mounting plate / adjustment plate, and when the first eccentric unit / second eccentric unit rotates, the mounting plate / adjustment plate is pushed to move along the direction of the first adjustment slot / second adjustment slot, and the rotation of the first eccentric unit / second eccentric unit is converted into the sliding of the mounting plate / adjustment plate, thereby improving the adjustment accuracy of the mounting plate / adjustment plate.

[0014] Specifically, the mounting plate and the adjustment plate are both provided with a plurality of pre-tightening units. The pre-tightening units on the mounting plate pass through the mounting plate from top to bottom and are screwed to the adjustment plate, and are elastically connected to the mounting plate; the pre-tightening units on the adjustment plate pass through the adjustment plate from top to bottom and are screwed to the mounting bracket, and are elastically connected to the adjustment plate. The pre-tightening units are used to apply a pre-tightening force to the mounting plate / adjustment plate to prevent the mounting plate / adjustment plate from being too loose, resulting in a decrease in adjustment accuracy, thereby improving the adjustment accuracy of the mounting plate / adjustment plate.

[0015] Specifically, the pre-tightening unit includes a second elastic unit and a second screw, the second screw is screwed to the adjustment plate or the mounting bracket, one end of the second elastic unit abuts against the mounting plate or the adjustment plate, and the other end abuts against the head of the second screw.

[0016] Preferably, the rotation angle of the light emitting unit is 30-60°.

[0017] Preferably, a limiter is further provided in the slot, which is used to limit the rotation angle of the light emitting unit to prevent the rotation angle of the light emitting unit from exceeding a set value, thereby causing the light emitting unit to escape from the slot, thereby improving the reliability of the slot.

[0018] Beneficial effects of the utility model:

[0019] The utility model proposes a device for quickly replacing and adjusting light sources for stage lamps. After the light-emitting unit passes through the mounting hole, the light-emitting unit is clamped in the clamping slot by rotating, thereby improving the convenience of replacing the light-emitting unit.
