Technical Field

The invention relates to the technical field of movable lighting devices, in particular to a movable lighting device capable of forming a complex geometric lighting effect.

Background

The existing movable lamp can improve the decorative effect of light through the rotation of the lamp; however, the mechanical movement design of the standard mobile light fixtures in the prior art does not allow for rapid movements, and thus cannot rapidly realize basic geometric shapes such as circles, squares, triangles, infinite symbols, etc. Take the geometry of a circle as an example; in one embodiment, as shown in fig. 5, these devices do not produce any geometry with infinite rotation when the head is in a vertical position. In another embodiment, other machines on the market have infinite rotation of the X axis. This means that they are not limited by the maximum rotation angle of the X-axis and can rotate continuously in two directions, so that the geometry of a circle is easy to make, only a small angle to the Y-axis is needed to make a continuous rotation of the X-axis. However, doing 360 degrees with the X-axis takes a long time, approximately 2 seconds. Thus, the beam moves too slowly, resulting in discontinuities in the light energy of the illumination output. As in fig. 6: the head is in a horizontal position. This is the best position for all moving heads with X and Y axes to achieve all geometries. In this position, the main problem is the speed of movement, since the weight of the elements to be moved and the gear ratio between the motor pulley and the X-or Y-axis pulley greatly reduce the speed of movement, causing a phenomenon of geometrical discontinuity.

The technical solution of the present solution is further explained by the following embodiments with reference to the accompanying drawings.

A mobile lighting device for creating complex geometric lighting effects, comprising: the lamp comprises a case 1, a lamp mounting frame 2, a lamp assembly 3, a first driving assembly 4 and a second driving assembly 5;

the lamp mounting rack 2 is rotatably mounted on the case 1 around an X axis as an axis; the lamp assembly 3 is rotatably arranged on the lamp mounting frame 2 around a Y axis as an axis; the X axis and the Y axis extend transversely and are parallel to the horizontal plane where the case is located;

the first drive assembly 4 comprises: a first driver 41, a first driving pulley 42, a first driven pulley 43, and a first timing belt 44;

the output end of the first driver 41 is connected to the first driving wheel 42, and is used for driving the first driving wheel 42 to rotate; the first driven wheel 43 is mounted on the lamp mounting bracket 2 and rotates around the X axis synchronously with the lamp mounting bracket 2; the first timing belt 44 connects the first driving pulley 42 and the first driven pulley 43 in synchronous rotation;

the second drive assembly 5 comprises: a second driver 51, a second driving pulley 52, a second driven pulley 53, and a second timing belt 54;

the second driver 51 is mounted on the lamp mounting bracket 2, and an output end of the second driver 51 is connected to the second driving wheel 52 and is used for driving the second driving wheel 52 to rotate; the second driven wheel 53 is mounted on the lamp assembly 3 and rotates around the Y axis synchronously with the lamp assembly 3; the second timing belt 54 connects the second driving pulley 52 and the second driven pulley 53 in a synchronous rotation manner.

The lighting device of the scheme can rotate at any angle, the lamp 31 can rotate rapidly at any angle around the X axis and the Y axis by driving the lamp 31 through the first driving assembly 4 and the second driving assembly 5, the lighting effect of any geometric shape is generated, and the problem that the rotation of the lamp 31 is limited by the position and the rotating speed of the lamp in the prior art is solved.

Specifically, the first driver 41 and the second driver 51 are well-known mechanisms having a function of driving rotation, such as motors; the first driver 41 can be disposed at any position within the cabinet 1, so that the first driving wheel 42 can be disposed in any orientation of the first driven wheel 43; in a preferred embodiment, the first driver 41 is fixed to the cabinet 1 and is located below the first driven wheel 43. As shown in fig. 2 and 4, the output end of the first driver 41 rotates to drive the first driving pulley 42 to rotate, and the first driven pulley 43 is driven to rotate by the first timing belt 44, so that the first driven pulley 43 rotates around the X-axis, and further the lamp mounting bracket 2 synchronously rotates around the X-axis, and the lamp assembly 3 on the lamp mounting bracket 2 is driven to rotate around the X-axis as a whole. After the second driver 51 is started, the output end of the second driver 51 rotates, and drives the second driving wheel 52 to rotate, and drives the second driven wheel 53 to synchronously rotate through the second synchronous belt 54, so that the second driven wheel 53 rotates around the Y axis as the axis; the second driven pulley 53 rotates around the Y axis as the axis in synchronization with the lamp unit 3, so that the lamp unit 3 can rotate on the Y axis. Therefore, the lamp assembly 3 can rotate around the X axis and the Y axis as the axes, and the lamp assembly 3 is driven to rotate at any angle through the common cooperation of the first driver 41 and the second driver 51, and the light effect of the complicated geometric light effect is formed.

Particularly, in the scheme, the lamp mounting rack 2 is rotatably arranged on the case 1; in fact, lamp mount 2 can be rotated 360 ° about the X axis in cabinet 1, regardless of the steric effects of the components within cabinet 1 on lamp mount 2 and lamp assembly 3 on lamp mount 2; for example, in fig. 2 and 4, the distance between the first driving pulley 42 and the first driven pulley 43 may be suitably extended so that the second driver 51 on the lamp mounting bracket 2 does not collide with the first driver 41 when the lamp mounting bracket 2 rotates through 360 °; meanwhile, the lamp assembly 3 can be rotated 360 ° about the Y-axis regardless of the steric hindrance of the lamp mount 2 in size to the lamp assembly 3; for example, by appropriately increasing the length of the lamp mounting bracket 2 in the X-axis direction and by appropriately moving the second actuator 51 away from the lamp assembly 3, it is ensured that the lamp assembly 3 can be rotated through 360 ° in the mounting bracket. It can be seen that the lamp assembly 3 of the present solution is such that a rotation of 360 deg. around the X-axis and the Y-axis, respectively, is achieved, i.e. the rotation of the lamp assembly 3 should not be affected by steric hindrance. Meanwhile, when the lamp assembly 3 rotates around the X-axis and the Y-axis, the lamp assembly 3 is indirectly driven to rotate around the X-axis by the first driver 41 and indirectly driven to rotate around the Y-axis by the second driver 51; that is, when the lamp assembly 3 rotates around the X-axis and the Y-axis, the rotation speed of the lamp assembly 3 is limited by the first driver 41 and the second driver 51, so that the lamp assembly 3 does not suddenly accelerate or decelerate, but the normal rotation speeds output by the first driver 41 and the second driver 51 are maintained, the rotation speeds are controlled and balanced during rotation, the continuity of the light effect is ensured, and the irradiated geometric shape is complete and continuous.

Among them, the lamp assembly 3 is a well-known mechanism having an output light source, such as a laser lamp, a life illumination lamp, or the like. Meanwhile, in the scheme, the lamp assembly 3 can be additionally provided with the lampshade 9 to cover the lamp 31 and the first heat dissipation structure 32 and the second heat dissipation structure 33 thereof, so that the lamp assembly 3 is prevented from being exposed.

Preferably, the ratio of the outer diameters between the first driving wheel 42 and the first driven wheel 43 is 1: (1-6);

the ratio of the outer diameters of the second driving wheel 52 and the second driven wheel 53 is 1: (1-6).

When the size of the first driving wheel 42 is designed to be equal to or smaller than the first driven wheel 43, the first driven wheel 43 can be decelerated through the first synchronous belt 44 when the first driving wheel 42 rotates, so that the lamp mounting frame 2 rotates in a decelerating manner as a whole, and when the lamp mounting frame 2 rotates too fast, the lamp assembly 2 and the lamp assembly 3 on the lamp mounting frame 2 are prevented from colliding with any part in the case 1 in the steric hindrance embodiment. Similarly, when the size of the second driving pulley 52 is smaller than that of the second driven pulley 53, the lamp assembly 3 can be effectively decelerated. And, for the ratio of the outer diameters between the first driving wheel 42 and the first driven wheel 43, or the outer diameter between the second driving wheel 52 and the second driven wheel 53, the ratio of 1: 6, more preferably 1: 5, further optimizing to 1: 4, optimally 1: 1, most preferably 1: (1-3.) the deceleration effect is moderate, and if the deceleration effect is too large, it will result in too slow movement of the lamp assembly 3, and if the deceleration effect is too small, it will result in too high rotation speed of the lamp assembly 3.

Preferably, the method further comprises the following steps: a tension assembly 6;

the tension assembly 6 comprises: a first tension plate 61, a tension stopper 63, and an elastic member 64;

the case 1 and/or the lamp mounting bracket 2 are/is provided with a second tensioning plate 62; the first tensioning plate 61 located on the chassis 1 is used for mounting the first driver 41; the first tensioning plate 61 on the lamp mounting 2 is used for mounting the second driver 51;

the first tensioning plate 61 is provided with a first fixing hole 611 and a first bayonet 612; the second tensioning plate 62 is provided with a second fixing hole 621 and a second bayonet 622; the first tensioning plate 61 is disposed on the second tensioning plate 62, and the tensioning limiting member 63 passes through the first fixing hole 611 and the second fixing hole 621, so that the first tensioning plate 61 is limited on the second tensioning plate 62; the first bayonet 612 and the second bayonet 622 form a height difference, one end of the elastic member 64 is detachably connected to the first bayonet 612, and the other end of the elastic member 64 is detachably connected to the second bayonet 622.

As shown in fig. 2 and 4, the second tensioning plate 62 may be disposed on the cabinet 1 and/or the lamp mount 2, and the first tensioning plate 61 may be mounted on the second tensioning plate 62 of the cabinet 1 and/or the second tensioning plate 62 of the lamp mount 2; and the first tension plate 61 is used for mounting the first driver 41 and the second driver 51, respectively; when the lighting device needs to mount the first driver 41 and the second driver 51, only the first tensioning plate 61 with the first driver 41 or the second driver 51 needs to be arranged on the second tensioning plate 62, the first fixing hole 611 is aligned with the second fixing hole 621, the first tensioning plate 61 and the second tensioning plate 62 are preliminarily fixed through the tensioning limiting piece 63, two ends of the elastic piece 64 are respectively connected with the first bayonet 612 and the second bayonet 622, and the elastic piece 64 has a pulling force effect on the first driver 41 or the second driver 51 after being fully expanded, so that the problem that the weight of the first driver 41 or the second driver 51 is too large is avoided; thereafter, the tension stopper 63 is further locked to the first tension plate 61 and the second tension plate 62; therefore, the tensioning assembly 6 can improve the installation convenience of the first driver 41 and the second driver 51, and the problem that the first driver 41 and the second driver 51 are too heavy and cannot be installed is avoided; meanwhile, the elastic member 64 can provide a buffer effect when the lighting device is impacted, so that the problem of deformation of the lighting device is avoided.

The tension limiting member 63 is a well-known mechanism having a locking function, such as a general clamp, a screw, a nut, and the like; the clamp directly fixes the first tension plate 61 and the second tension plate 62; the screws may be directly fitted into the first and second bayonets 612 and 622 and locked by the nuts.

The elastic member 64 is a well-known mechanism having elastic expansion and contraction, such as a spring, an elastic band, or the like.

Preferably, at least one of the first fixing hole 611 and the second fixing hole 621 is an elongated hole, and the tension limiting member 63 is limited to move in the first fixing hole 611 and/or the second fixing hole 621, so that the first tensioning plate 61 and the second tensioning plate 62 can move relatively.

As shown in fig. 2 and 4, the first fixing hole 611 and/or the second fixing hole 621 are elongated, that is, the elongated holes can provide a limiting movement for the tension limiting member 63; for example, in one embodiment, the second fixing holes 621 are elongated holes, and the first fixing holes 611 are round holes; the tension limiting member 63 extends into the second fixing hole 621 after passing through the first fixing hole 611; when the first tensioning plate 61 and the second tensioning plate 62 are displaced relatively, under the limiting action of the tensioning limiting part 63, the tensioning limiting part 63 is displaced relatively in the second fixing hole 621; the tensioning limiting part 63 can pass through the first fixing hole 611 and then extend into the second fixing hole 621, so that the tensioning limiting part 63 can be limited and movable between two ends of the second fixing hole 621, further, the matching position between the first tensioning plate 61 and the second tensioning plate 62 can be flexibly adjusted, the elastic expansion of the elastic part 64 is matched, a buffering effect can be provided when the lighting device is oscillated, an assisting force can be provided when the case 1 bears the first driver 41 and the lamp mounting block 2 bears the second driver 51, and the fixing stability of the first driver 41 and the second driver 51 is improved through the elastic expansion of the elastic part 64.

Similarly, in one embodiment, the second fixing holes 621 are round holes, and the first fixing holes 611 are elongated holes; in one embodiment, the first fixing hole 611 and the second fixing hole 621 are elongated holes.

Meanwhile, since the first heat dissipation structures 32 are transversely distributed and a gap is formed between the first heat dissipation plate 321 and the first heat dissipation plate 321, when the first heat dissipation plate 321 rotates, the heat dissipation position changes, and air flows between the first heat dissipation plate 321 and the first heat dissipation plate 321, thereby improving the heat dissipation effect.

Meanwhile, the lamp 31 and the first heat dissipation structure 32 are more convenient to install due to the fact that the first heat dissipation structure 32 is connected with the lamp installation frame 2. When the disc stopper 24 is mounted, the second driven wheel 53 is mounted on the first heat dissipation structure 32, the connecting column 23 is aligned with the disc connecting hole 22 of the fixed connecting disc 21, and the direct disc stopper 24 is fixed in the disc connecting hole 22, so that the disc stopper 24 is limited; finally, the second heat dissipation structure 33 and the lamp 31 are installed. The disk stopper 24 is a known mechanism having a fixing function, such as a clamp, a bolt, etc.; the clamp can clamp the connecting column 23, so that the connecting column 23 is limited in the disc connecting hole 22; the bolts may be fitted to the connection cylinders 23 by a screw structure so that the connection cylinders 23 are restrained in the disc connection holes 22.

Further optimally, the method also comprises the following steps: a heat radiation fan 7;

a heat dissipation groove 322 with a downward opening is formed between the first heat dissipation plate 321 and the first heat dissipation plate 321; the heat dissipation fan 7 is mounted on the lamp mounting bracket 2 and located below the heat dissipation groove 322; the air outlet of the heat dissipation fan 7 is aligned with the opening of the heat dissipation groove 322.

As shown in fig. 2 and 4, the heat dissipation fan 7 is aligned with the first heat dissipation plate 321, and on the basis that the heat dissipation effect is improved by rotating the first heat dissipation plate 321, the heat dissipation fan 7 is disposed at the opening of the first heat dissipation plate 321, and the heat dissipation fan 7 blows air into the first heat dissipation plate 321, so that the heat exchange speed inside the first heat dissipation plate 321 is improved, and the heat dissipation effect of the first heat dissipation plate 321 is further improved. Especially, when the lamp assembly rotates 360 degrees, the heat dissipation fan 7 can blow air flow into the heat dissipation groove 322 while the lamp rotates, so that the heat exchange effect is improved.

Preferably, the lamp assembly 3 comprises: a second heat dissipation structure 33; the second heat dissipation structure 33 is disposed on the top of the first heat dissipation structure 32; the second heat dissipation structures 33 are arranged in pairs, and a receiving cavity 34 for placing the lamp 31 is formed between the two second heat dissipation structures 33.

As shown in fig. 2 and 4, the second heat dissipation structure 33 is disposed on top of the first heat dissipation structure 32; the second heat dissipation structures 33 are arranged in pairs to form accommodating cavities 34, which can be used for accommodating the lamps 31. Therefore, the bottom of the lamp 31 is radiated by the first heat dissipation structure 32, the left and right sides of the lamp 31 are radiated by the second heat dissipation structure 33, the heat dissipation effect of the lamp 31 is optimal, and in combination with the fact that the lamp 31 can rotate 360 degrees around the X axis and the Y axis, the first heat dissipation structure 32 and the second heat dissipation structure 33 have a fast heat exchange effect when rotating 360 degrees, and therefore it is ensured that the lighting device can dissipate heat along with the angle adjustment of the lamp 31.

Preferably, the second heat dissipation structure 33 is composed of a plurality of second heat dissipation plates 331 distributed vertically, and the second heat dissipation plates 331 are located outside the accommodating cavity 34.

As shown in fig. 2 and 4, the first heat dissipation structure 32 is composed of first heat dissipation plates 321 distributed transversely, the second heat dissipation structure 33 is composed of second heat dissipation plates 331 distributed vertically, and the first heat dissipation structure 32 and the second heat dissipation structure 33 extend in different directions, respectively, so that the heat dissipation effect of the lamp 31 can be improved when the lamp assembly 3 rotates.

Preferably, the method further comprises the following steps: a locking assembly 8;

the locking assembly 8 is arranged outside the case 1.

The locking assembly 8 comprises: a first locking plate 81, a second locking plate 82, and a lock stopper 83;

the first locking plate 81 is installed on the case 1; the second locking plate 82 is fixed to the first locking plate 81 by the locking limit piece 83; the first locking plate 81 is provided with a first locking port 84; the second locking plate 82 is provided with a second locking port 85; the first locking port 84 abuts the second locking port 85 to form a locking cavity 86.

As shown in fig. 3, when the lighting device needs to be fixed at a certain position, the locking assembly 8 only needs to be fixed at a certain position; in one embodiment, the first locking plate 81 is provided with a first locking opening 84; the second locking plate 82 is provided with a second locking port 85; a locking cavity 86 is formed between the first locking opening 84 and the second locking plate 82, and the locking cavity 86 is limited at a certain object (such as a rod or other columnar structure) and locked by the locking limiting member 83. In another embodiment, the second locking plate 82 can be coupled to a clamp that holds another object to which the lighting device is to be secured.

The lock stopper 83 is a well-known mechanism having a stopper function, such as a clamp or a bolt. The clamp directly clamps the first locking plate 81 and the second locking plate 82, so that the first locking plate 81 and the second locking plate 82 are fixed in position; the bolts can be passed through the first and second lock plates 81 and 82 and then engaged with the nuts.
