[0021] like Figures 1 to 6 As shown, a bulb holder with an electrically adjustable bulb center point includes a base 1 having a mounting hole 11 in which a bulb 2 is detachably disposed; Mounting plate 3, the base 1 is movably disposed below the mounting plate 3, and the bottom end of the mounting plate 3 is provided with a plurality of protruding limiting posts 31. The base 1 is provided with a plurality of movable holes 12 extending along the first direction, and each limiting post 31 is movably inserted into the corresponding movable hole 12. An adjustment component 4 is connected to the base 1. The adjustment component 4 is used to drive the base 1 to move along the first direction, thereby adjusting the center of the bulb 2. The adjustment assembly 4 includes a drive member 41, a cam 42, a screw 43, and a nut 44. The drive member 41 is provided on one side of the base 1. The output end of the drive member 41 is connected to the cam 42. A rotating hole 13 is also provided on the base 1. The cam 42 is rotatably disposed in the rotating hole 13. The top end of the cam 42 is provided with the screw 43. The screw 43 is rotatably inserted into the mounting plate 3, and the end of the screw 43 extending above the mounting plate 3 is provided with the nut 44. This means that when the drive member 41 drives the cam 42 to rotate in the rotating hole 13, the cam 42 pushes the base 1 to move along the first direction, thereby adjusting the center of the bulb 2.

[0022] The bulb holder in this design includes a base 1 and a mounting plate 3. The bulb 2 is installed in the mounting hole 11 of the base 1 to emit light to the outside. The base 1 is movably positioned at the lower end of the mounting plate 3. The base 1 is driven to reciprocate along a first direction by the adjustment component 4. Specifically, when the drive component 41 in the adjustment component 4 drives the cam 42 to rotate in the rotating hole 13, the cam 42 abuts against the side wall of the rotating hole 13. Therefore, the continuously rotating cam 42 will push the base 1 to move continuously. The guide during the movement of the base 1 is achieved by the cooperation of the limiting post 31 and the movable hole 12. When the cam 42 rotates, the nut 44 on the screw 43 also moves synchronously. The nut 44 is always pressed against the upper surface of the mounting plate 3. The effective contact between the cam 42 and the base 1 is maintained by the pressing of the mounting plate 3, which facilitates adjustment. When the cam 42 rotates, it will drive the base 1 to reciprocate along the first direction. Since the bulb 2 is set on the base 1, the bulb 2 will also move synchronously with the base 1, thereby adjusting the (light-emitting) center of the bulb 2.

[0023] The above structure uses a drive unit 41 to automatically move the base 1 / bulb 2, upgrading the existing manual calibration to electric calibration. Adjustment can be performed without opening the mounting housing of the lamp. That is, the bulb holder is wrapped inside the housing and there is no need to drill holes for screwdrivers. Under sealed conditions, the drive unit 41 drives the cam 42 to rotate to adjust the position of the light-emitting center of the bulb 2, so that the bulb 2 can achieve the best light-emitting effect. In addition, the above tool-free intrusive adjustment method can keep the lamp intact and will not affect the original waterproof effect of the lamp.

[0024] Furthermore, the lower surface of the top of the base 1 is also provided with a spring piece 5, the spring piece 5 is provided with a connecting hole 51, the limiting post 31 is provided with a through hole 311, and the fixing member passes through the connecting hole 51 and the through hole 311 in sequence to connect the spring piece 5 and the mounting plate 3. The inner part of the spring piece 5 extends upward at an angle to form a pressing part 52, which abuts against the lower surface of the base 1.

[0025] In this embodiment, as Figure 2 and Figure 4 As shown, the base 1 for mounting the bulb 2 is pressed tightly by the spring piece 5, which enables quick installation and replacement of the bulb 2 / bulb holder. The spring piece 5 is located below the base 1 to fix the bulb 2. The spring piece 5 is long and narrow, with a small portion of each end extending upwards and bending to form a clamping part 52. The clamping part 52 presses the mounting base to prevent it from shaking. The spring piece 5 has a connecting hole 51. The limiting post 31 has a hollow structure with a through hole 311 inside. The fastener (which can actually be a bolt) passes through the connecting hole 51 and is inserted into the through hole 311 of the limiting post 31 to fix the spring piece 5 and the mounting plate 3.

[0026] Furthermore, the base 1 has spring pieces 5 on both sides of its lower surface. Two spring pieces 5 are spaced apart on the left and right sides of the bottom of the base 1, and the two spring pieces 5 abut against the two sides of the base 1 respectively, making the base 1 more stable to install.

[0027] Furthermore, the base 1 has movable holes 12 at each of its four corners, and the mounting plate 3 has four corresponding limiting posts 31 at its bottom end. Specifically, as shown... Figure 4 As shown, the movement of the base 1 and the bulb 2 is achieved through the cooperation of the movable holes 12 at the four corners of the base 1 and the four limiting posts 31 on the mounting plate 3, resulting in better stability. The connecting hole 51 of the spring piece 5 partially overlaps with the movable hole 12, so that the limiting post 31 in the movable hole 12 can be aligned with the connecting hole 51, and then fixed by the fastener. Each spring piece 5 is fixed to the mounting plate 3 by cooperating with the fastener through the connecting holes 51 at both ends.

[0028] Furthermore, the driving component 41 is a motor. By using a motor to drive the cam 42 to rotate continuously, precise control of the cam 42's speed, direction, and position can be achieved, meeting automation requirements. Moreover, the structure is simple, the cost is low, and it is easy to install and maintain.

[0029] Furthermore, fans 6 for heat dissipation are also provided on both sides of the base 1. In this embodiment, as... Figures 1 to 2 As shown, a blower fan 6 is installed on one side of the bulb 2, and an exhaust fan 6 is installed on the other side of the bulb 2. The fans 6 are fixed to the mounting plate 3 by a bracket, which has the function of efficient convection heat dissipation. The two fans 6 form a forced air duct, which quickly draws in cold air and exhausts hot air, greatly improving heat dissipation efficiency, avoiding local overheating, and reducing thermal stress damage. In addition, it can also reduce dust accumulation. The directional airflow can inhibit the accumulation of dust inside the lamp and extend the maintenance cycle.

[0030] Furthermore, the mounting plate 3 is also equipped with a blower 7, the air outlet of which faces the bulb 2. Typically, the adjustment component 4 is located on one side of the base 1, and the blower 7 is located on the other side of the base 1, with the air outlet of the blower 7 facing the bulb 2. This can accelerate air circulation, quickly remove the heat generated by the bulb 2 during operation, avoid the decrease in luminous efficiency caused by high temperature, slow down the aging of the bulb beads, and extend the service life of the bulb 2.

[0031] Furthermore, a heat insulation plate bracket 8 is provided above the mounting plate 3, which is used to install the heat insulation plate. Since the mounting plate 3 is directly above the bulb 2, in order to insulate heat, a heat insulation plate bracket 8 is fixed above the mounting plate 3 by three connecting columns. The heat insulation plate bracket 8 has an opening in the middle, which does not affect the light emitted by the bulb 2. Then, the heat insulation plate is installed on the heat insulation plate bracket 8. The heat insulation plate (not shown in the figure) blocks the high temperature and prevents the heat emitted by the bulb 2 from being directly transferred to the lamp cover or surrounding components, avoiding deformation, aging or safety hazards caused by high temperature.

[0032] In addition, heat-conducting grooves or metal plating can be set on the heat insulation sheet to improve heat dissipation efficiency, guide heat dissipation in a directional manner, and extend the life of bulb 2.

[0033] In particular, this utility model also proposes a lamp fixture including the aforementioned electrically adjustable bulb holder. This lamp fixture includes any of the aforementioned electrically adjustable bulb holders, and therefore has the same beneficial effects as the aforementioned electrically adjustable bulb holders, which will not be elaborated further here; moreover, this electrically adjustable bulb holder is particularly suitable for use in stage lights.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
