Description

Technical Field

[0001] The present invention relates to the technical field of mobile lighting devices, and in particular to a mobile lighting device capable of forming complex geometric lighting effects. Background Art

[0002] Existing mobile lamps can improve the decorative effect of lights by rotating themselves; however, the mechanical movement design of standard mobile lamps in the prior art does not allow certain movements to be performed quickly, so basic geometric shapes such as circles, squares, triangles, infinity symbols, etc. cannot be quickly realized. Take the geometric shape of a circle as an example; in one embodiment, Figure 5 , these devices cannot produce any geometry with infinite rotation when the head is in a vertical position. In another example, 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 both directions, so it is easy to make circular geometries, just give the Y axis a small angle and let the X axis do a continuous rotation. However, it takes a long time to do 360 degrees with the X axis, almost 2 seconds. Therefore, the light beam moves too slowly, resulting in discontinuous light energy output for the lighting. As Figure 6 Middle: The head is in horizontal position. This is the optimal 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 element to be moved and the gear ratio between the motor pulley and the X or Y pulley significantly reduce the movement speed, resulting in discontinuities in the geometry.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0048] The technical solution of this solution is further explained below through specific implementation methods in conjunction with the accompanying drawings.

[0049] A mobile lighting device for forming complex geometric lighting effects, comprising: a chassis 1, a lamp mounting frame 2, a lamp assembly 3, a first drive assembly 4 and a second drive assembly 5;

[0050] The lamp mounting frame 2 is rotatably mounted on the chassis 1 around the X axis; the lamp assembly 3 is rotatably mounted on the lamp mounting frame 2 around the Y axis; the X axis and the Y axis extend laterally and are respectively parallel to the horizontal plane where the chassis is located;

[0051] The first driving assembly 4 includes: a first driver 41, a first driving wheel 42, a first driven wheel 43 and a first synchronous belt 44;

[0052] The output end of the first driver 41 is connected to the first driving wheel 42, and is used to drive the first driving wheel 42 to rotate; the first driven wheel 43 is installed on the lamp mounting frame 2, and rotates synchronously with the lamp mounting frame 2 around the X axis; the first synchronous belt 44 connects the first driving wheel 42 and the first driven wheel 43 to rotate synchronously;

[0053] The second driving assembly 5 includes: a second driver 51, a second driving wheel 52, a second driven wheel 53 and a second synchronous belt 54;

[0054] The second driver 51 is installed on the lamp mounting frame 2, and the output end of the second driver 51 is connected to the second driving wheel 52 for driving the second driving wheel 52 to rotate; the second driven wheel 53 is installed on the lamp assembly 3 and rotates around the Y axis synchronously with the lamp assembly 3; the second synchronous belt 54 connects the second driving wheel 52 and the second driven wheel 53 for synchronous rotation.

[0055] The lighting device of the present solution can rotate at any angle. By driving the lamp 31 with the first drive component 4 and the second drive component 5, the lamp 31 can be quickly rotated at any angle around the X-axis and the Y-axis to produce a lighting effect of any geometric shape, thereby solving the problem in the prior art that the rotation of the lamp 31 is limited by the position and rotation speed of the lamp.

[0056] Specifically, the first driver 41 and the second driver 51 are known mechanisms with a driving and rotating function, such as a motor; the first driver 41 can be set at any position in the chassis 1, so that the first driving wheel 42 can be set at any position of the first driven wheel 43; in a preferred embodiment, the first driver 41 is fixed to the chassis 1 and is located below the first driven wheel 43. Figure 2 and Figure 4 , the output end of the first driver 41 rotates, driving the first driving wheel 42 to rotate, and driving the first driven wheel 43 to rotate through the first synchronous belt 44, so that the first driven wheel 43 rotates around the X-axis, and then the lamp mounting frame 2 rotates synchronously around the X-axis, driving the lamp assembly 3 on the lamp mounting frame 2 to rotate around the X-axis as a whole. After starting the second driver 51, 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 rotate synchronously through the second synchronous belt 54, so that the second driven wheel 53 rotates around the Y-axis as the axis; the second driven wheel 53 and the lamp assembly 3 rotate synchronously around the Y-axis as the axis, so that the lamp assembly 3 can rotate on the Y-axis. Therefore, the lamp assembly 3 of this solution can rotate around the X-axis and the Y-axis as the axis, and through the cooperation of the first driver 41 and the second driver 51, the lamp assembly 3 is driven to rotate at any angle, and a lighting effect with a complex geometric lighting effect is formed.

[0057] It is particularly important that, in this solution, the lamp mounting frame 2 is rotatably mounted on the chassis 1; in fact, without considering the steric effect of the components in the chassis 1 on the lamp mounting frame 2 and the lamp assembly 3 on the lamp mounting frame 2, the lamp mounting frame 2 can be rotated 360° around the X axis on the chassis 1; for example Figure 2 and Figure 4In the embodiment, the distance between the first driving wheel 42 and the first driven wheel 43 can be appropriately lengthened so that the second driver 51 on the lamp mounting frame 2 will not collide with the first driver 41 when the lamp mounting frame 2 rotates 360°; at the same time, without considering the steric resistance of the lamp assembly 3 to the lamp mounting frame 2 by the size of the lamp mounting frame 2, the lamp assembly 3 can rotate 360° around the Y axis; for example, the length of the lamp mounting frame 2 in the X axis direction can be appropriately increased, and the second driver 51 can be appropriately away from the lamp assembly 3 to ensure that the lamp assembly 3 can rotate 360° in the mounting frame. It can be seen from this that the lamp assembly 3 of this solution can realize 360° rotation around the X axis and the Y axis respectively, that is, the rotation of the lamp assembly 3 should not be affected by steric resistance. At the same time, when the lamp assembly 3 rotates around the X-axis and the Y-axis, the lamp assembly 3 is indirectly driven by the first driver 41 to rotate around the X-axis, and is indirectly driven by the second driver 51 to rotate around the Y-axis; 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 the lamp assembly 3 will not suddenly accelerate or decelerate, but maintain the normal rotation speed output by both the first driver 41 and the second driver 51, ensuring that the rotation speed is controllable and balanced during rotation, ensuring the continuity of the lighting effect, and thus the illuminated geometric shape is complete and coherent.

[0058] The lamp assembly 3 is a well-known mechanism with an output light source, such as a laser lamp, a living lighting lamp, etc. Meanwhile, in this solution, the lamp assembly 3 may also include a lampshade 9 to cover the lamp 31 and its first heat dissipation structure 32 and the second heat dissipation structure 33 to prevent the lamp assembly 3 from being exposed.

[0059] Preferably, the outer diameter ratio between the first driving wheel 42 and the first driven wheel 43 is 1:(1-6);

[0060] The outer diameter ratio between the second driving wheel 52 and the second driven wheel 53 is 1:(1-6).

[0061] 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 by the first synchronous belt 44 when the first driving wheel 42 rotates, so that the rotation of the lamp mounting frame 2 as a whole is decelerated. When the lamp mounting frame 2 rotates too fast, the lamp mounting frame 2 and the lamp assembly 3 on the lamp mounting frame 2 are prevented from colliding with any component in the chassis 1 in the embodiment with steric obstruction. Similarly, when the size of the second driving wheel 52 is smaller than the size of the second driven wheel 53, the lamp assembly 3 can be effectively decelerated. As for the outer diameter ratio between the first driving wheel 42 and the first driven wheel 43, or the outer diameter ratio between the second driving wheel 52 and the second driven wheel 53, the ratio can be preferably 1:6, more preferably 1:5, further optimized to 1:4, and can be optimized to 1:1, and the best is 1:(1-3]. The deceleration effect should be moderate. If the deceleration effect is too large, the lamp assembly 3 will move too slowly. If the deceleration effect is too small, the rotation speed of the lamp assembly 3 will be too high.

[0062] Preferably, it also includes: a tensioning assembly 6;

[0063] The tensioning assembly 6 includes: a first tensioning plate 61, a tensioning limiter 63 and an elastic member 64;

[0064] The chassis 1 and / or the lamp mounting frame 2 are provided with a second tensioning plate 62; the first tensioning plate 61 located in the chassis 1 is used to install the first driver 41; the first tensioning plate 61 located in the lamp mounting frame 2 is used to install the second driver 51;

[0065] 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 arranged on the second tensioning plate 62, and the tensioning limiter 63 passes through the first fixing hole 611 and the second fixing hole 621, so that the first tensioning plate 61 is limited to 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.

[0066] like Figure 2 and Figure 4The second tensioning plate 62 can be arranged on the chassis 1 and / or the lamp mounting frame 2, and the first tensioning plate 61 can be installed on the second tensioning plate 62 of the chassis 1 and / or the second tensioning plate 62 of the lamp mounting frame 2; and the first tensioning plate 61 is used to install the first driver 41 and the second driver 51 respectively; when the lighting device needs to install the first driver 41 and the second driver 51, it is only necessary to set the first tensioning plate 61 with the first driver 41 or the second driver 51 on the second tensioning plate 62, align the first fixing hole 611 with the second fixing hole 621, preliminarily fix the first tensioning plate 61 and the second tensioning plate 62 by the tensioning stopper 63, and tighten the two ends of the elastic member 64. The ends are respectively connected to the first bayonet 612 and the second bayonet 622, so that the elastic member 64 has a pulling force on the first driver 41 or the second driver 51 after being fully opened, thereby avoiding the problem of excessive weight of the first driver 41 or the second driver 51; thereafter, the tensioning limit member 63 is further locked to the first tensioning plate 61 and the second tensioning plate 62; thereby, the tensioning assembly 6 can improve the installation convenience of the first driver 41 and the second driver 51, and avoid the problem of the first driver 41 and the second driver 51 being too heavy to be installed; at the same time, the elastic member 64 can provide a buffering effect when the lighting device is impacted, thereby avoiding the problem of deformation of the lighting device.

[0067] Among them, the tensioning limiter 63 is a well-known mechanism with a locking function, such as a general clamp, screw and nut, etc.; the clamp directly fixes the first tensioning plate 61 and the second tensioning plate 62; the screw can be directly matched in the first bayonet 612 and the second bayonet 622, and locked by the nut.

[0068] The elastic member 64 is a well-known elastic stretchable mechanism, such as a spring, an elastic band, etc.

[0069] More preferably, at least one of the first fixing hole 611 and the second fixing hole 621 is a long strip-shaped hole, and the tensioning limiter 63 is limited and movable 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.

[0070] like Figure 2 and Figure 4, the first fixing hole 611 and / or the second fixing hole 621 are in the shape of an elongated strip, that is, the elongated holes can provide limited movement for the tensioning limiter 63; for example, in one embodiment, the second fixing hole 621 is in the shape of an elongated strip, and the first fixing hole 611 is in the shape of a round hole; the tensioning limiter 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 relatively displaced, under the limiting action of the tensioning limiter 63, the tensioning limiter 63 is relatively displaced in the second elongated fixing hole 621; the tensioning limiter 63 can pass through The first fixing hole 611 extends into the second fixing hole 621 at the rear, so that the tensioning limiter 63 can be limited and movable between the two ends of the second fixing hole 621, and then the matching position between the first tensioning plate 61 and the second tensioning plate 62 can be flexibly adjusted. In combination with the elastic expansion and contraction of the elastic member 64, a buffering effect can be provided when the lighting device is subjected to vibration, and an assist can be provided when the chassis 1 carries the first driver 41 and the lamp mounting frame 2 carries the second driver 51, so as to improve the fixing stability of the first driver 41 and the second driver 51 through the elastic expansion and contraction of the elastic member 64.

[0071] Similarly, in one embodiment, the second fixing hole 621 is a round hole, and the first fixing hole 611 is an elongated hole; in one embodiment, both the first fixing hole 611 and the second fixing hole 621 are elongated holes.

[0072] Preferably, the lamp assembly 3 comprises: a lamp 31 and a first heat dissipation structure 32;

[0073] The lamp 31 is connected to the first heat dissipation structure 32; the first heat dissipation structure 32 is provided with a plurality of first heat dissipation plates 321 distributed laterally; the first heat dissipation plates 321 are separated by gaps; the outer side of the first heat dissipation structure 32 is rotatably connected to the lamp mounting frame 2.

[0074] like Figure 2 and Figure 4 In this solution, the first heat dissipation structure 32 is preferably used in conjunction with the lamp 31. The first heat dissipation structure 32 is connected to the lamp 31, so that the first heat dissipation structure 32 and the lamp 31 can be connected, and the two can be rotated 360 degrees synchronously; the first heat dissipation structure 32 can adjust its own position when rotating to dissipate heat in time. At the same time, since the first heat dissipation structure 32 is horizontally 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 circulates between the first heat dissipation plate 321 and the first heat dissipation plate 321, thereby improving the heat dissipation effect.

[0075] More preferably, the lamp mounting frame 2 is provided with a fixed connection disk 21 that rotates around the Y axis; the fixed connection disk 21 is provided with a disk connection hole 22;

[0076] The second driven wheel 53 is installed on one side of the first heat dissipation structure 32 and rotates synchronously with the second driven wheel 53; a connecting column 23 is provided on the other side of the first heat dissipation structure 32; the connecting column 23 extends into the disk connecting hole 22 and is detachably limited in the disk connecting hole 22 by the disk limiting member 24.

[0077] like Figure 2 and Figure 4 In this solution, the first heat dissipation structure 32 is preferably rotatably mounted on the lamp mounting frame 2, and the lamp mounting frame 2 drives the first heat dissipation structure 32 to rotate, that is, the heat dissipation angle of the first heat dissipation structure 32 can be controlled by the first driver 41 and the second driver 51. When the lighting device is used, the first heat dissipation plate 321 is directly heat-exchanged by starting the first driver 41 and the second driver 51. At the same time, since the technical point of connecting the first heat dissipation structure 32 to the lamp mounting frame 2 is adopted, the installation of the lamp 31 and the first heat dissipation structure 32 is more convenient. During installation, it is only necessary to install the second driven wheel 53 on the first heat dissipation structure 32, and then align the connecting column 23 with the disk connection hole 22 of the fixed connection disk 21, and the direct disk limiter 24 will be fixed in the disk connection hole 22, so that the disk limiter 24 is limited; finally, the second heat dissipation structure 33 and the lamp 31 are installed. Among them, the disk limiter 24 is a well-known mechanism with 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 disk connecting hole 22; the bolt can be matched with the connecting column 23 through a threaded structure so that the connecting column 23 is limited in the disk connecting hole 22.

[0078] Further optimized, it also includes: a heat dissipation fan 7;

[0079] A downwardly opening heat dissipation slot 322 is formed between the first heat dissipation plates 321 ; the heat dissipation fan 7 is installed on the lamp mounting frame 2 and is located below the heat dissipation slot 322 ; the air outlet of the heat dissipation fan 7 is aligned with the opening of the heat dissipation slot 322 .

[0080] like Figure 2 and Figure 4 The cooling fan 7 is aligned with the first heat sink 321. Based on the fact that the first heat sink 321 can rotate to improve the heat dissipation effect, the cooling fan 7 is arranged at the opening of the first heat sink 321. The cooling fan 7 blows air to the inside of the first heat sink 321, thereby improving the heat exchange speed inside the first heat sink 321 and further improving the heat dissipation effect of the first heat sink 321. In particular, when the lamp assembly rotates 360 degrees, the cooling fan 7 can blow air into the heat sink 322 while the lamp rotates, thereby improving the heat exchange effect.

[0081] Preferably, the lamp assembly 3 comprises: a second heat dissipation structure 33; the second heat dissipation structure 33 is arranged 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 two second heat dissipation structures 33.

[0082] like Figure 2 and Figure 4 , the second heat dissipation structure 33 is arranged on the top of the first heat dissipation structure 32; the second heat dissipation structures 33 are arranged in pairs to form a receiving cavity 34, which can be used to receive the lamp 31. Therefore, the bottom of the lamp 31 is provided with heat dissipation by the first heat dissipation structure 32, and the left and right sides of the lamp 31 are provided with heat dissipation by the second heat dissipation structure 33, and the heat dissipation effect of the lamp 31 is the best. Combined 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, thereby ensuring that the lighting device will be accompanied by heat dissipation when the angle of the lamp 31 is adjusted.

[0083] 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 .

[0084] like Figure 2 and Figure 4 The first heat dissipation structure 32 is composed of a first heat dissipation plate 321 distributed laterally, and the second heat dissipation structure 33 is composed of a second heat dissipation plate 331 distributed vertically. The first heat dissipation structure 32 and the second heat dissipation structure 33 extend in different directions respectively, which can improve the heat dissipation effect of the lamp 31 when the lamp assembly 3 rotates.

[0085] Preferably, it also includes: a locking assembly 8;

[0086] The locking assembly 8 is disposed on the outside of the chassis 1 .

[0087] The locking assembly 8 includes: a first locking plate 81, a second locking plate 82 and a locking limiter 83;

[0088] The first locking plate 81 is installed on the chassis 1; the second locking plate 82 is fixed to the first locking plate 81 by the locking limiter 83; the first locking plate 81 is provided with a first locking opening 84; the second locking plate 82 is provided with a second locking opening 85; the first locking opening 84 and the second locking opening 85 are abutted against each other to form a locking cavity 86.

[0089] like Figure 3When the lighting device needs to be fixed at a certain position, it is only necessary to fix the locking assembly 8 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 opening 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 to a certain object (such as a columnar structure such as a rod) and locked by the locking limiter 83. In another embodiment, the second locking plate 82 can be connected to a clamp, and the clamp clamps another object, so that the lighting device is fixed to the object.

[0090] The locking limiter 83 is a well-known mechanism with a limit function, such as a clamp or a bolt, etc. The clamp directly clamps the first locking plate 81 and the second locking plate 82 to fix the positions of the first locking plate 81 and the second locking plate 82; the bolt can pass through the first locking plate 81 and the second locking plate 82 and then cooperate with the nut.
