Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a mini small-angle high-brightness lamp. Background Art

[0002] In addition to lighting, lamps can also be used to create background effects in entertainment venues such as stages. Due to the limitations of the structural setting, existing stage beam lamps have the following problems:

[0003] 1. Due to the limitation of power cord and signal line, the lamp body cannot rotate infinitely clockwise / counterclockwise horizontally. After reaching the set angle, it needs to rotate in the opposite direction, which may easily lead to wire breakage. In addition, the light projection effect is limited and cannot meet the needs of stage and program.

[0004] 2. During the optical projection process, there is stray light around the effective light spot, which affects the brightness and light projection effect.

[0034] Below, in conjunction with the accompanying drawings and specific implementation methods, the utility model is further described:

[0035] like Figure 1-3 As shown, a mini small-angle high-brightness lamp comprises a lamp holder assembly 1 and a lamp body assembly 2, wherein the lamp body assembly 2 comprises an oscillating head bracket 21, a horizontal rotation mechanism 3 is arranged between the lamp holder assembly 1 and the oscillating head bracket 21, and an angle adjustment mechanism 4 is arranged between the oscillating head bracket 21 and the lamp body assembly 2;

[0036] The horizontal rotation mechanism 3 includes a coaxial connecting shaft 31 and a connecting wheel 32. The connecting shaft 31 is a through hollow structure. One end of the connecting shaft 31 is non-rotatably connected to the lamp holder assembly 1. A conductive slip ring 5 connected to the lamp holder assembly 1 is provided in the hollow part of the connecting shaft 31. The connecting wheel 32 is only rotatably sleeved on the outer side of the connecting shaft 31 through a first bearing 10. Two or more first bearings 10 are provided. One end of the connecting wheel 32 is non-rotatably connected to the oscillating bracket 21.

[0037] The horizontal rotation mechanism 3 further includes a horizontal driving assembly 33 that drives the connecting wheel 32 to rotate, and the horizontal driving assembly 33 is eccentrically arranged with the connecting wheel 32;

[0038] The lamp holder assembly 1 is provided with an electrically connected power connector 20 and a control module (not shown in the figure), and the lamp body assembly 2 is electrically connected to the power connector 20 and the control module via a conductive slip ring 5 .

[0039] In this embodiment, the above structure, through the combined design of the connecting shaft 31, the connecting wheel 32 and the conductive slip ring 5, enables the lamp body assembly 2 to rotate horizontally and infinitely relative to the lamp holder assembly 1 while ensuring that the lamp body assembly 2 is electrically connected to the lamp holder assembly 1, so that the lamp can achieve a high-speed dazzling light projection effect and avoid the situation where the power cord is stuck, thereby greatly improving reliability.

[0040] In this embodiment, two or more first bearings 10 are provided to improve the stability of the horizontal infinitely high-speed rotation of the lamp body assembly 2 .

[0041] Further, such as Figure 1 , 2 As shown, in order to realize highly reliable rotation drive of the connecting wheel 32 and the lamp body assembly 2, the horizontal drive assembly 33 includes a horizontal driver 331, a first main synchronous pulley 332 and a first transmission synchronous belt 333;

[0042] The horizontal driver 331 is connected to the lamp holder assembly 1, the first main synchronous pulley 332 is connected to the driving end of the horizontal driver 331, the connecting wheel 32 is a slave synchronous pulley, and the two ends of the first transmission synchronous belt 333 are respectively meshed and connected with the first main synchronous pulley 332 and the connecting wheel 32.

[0043] Further, such as Figure 2 , 3 As shown, in order to achieve positioning control of the horizontal rotation of the lamp body assembly 2, the horizontal driving assembly 33 also includes a reading disk 334 arranged on the first main synchronous pulley 332, and a photoelectric sensor 335 for sensing the reading disk 334.

[0044] Further Figure 2 , 3 As shown, the lamp holder assembly 1 includes a base bracket 11, and the base bracket 11 includes a bottom plate 111. Vertical plates 112 are relatively arranged on both sides of the bottom plate 111, and an installation chamber is formed between the bottom plate 111 and the vertical plate 112. The lamp holder assembly 1 also includes an outer shell 12 that wraps the installation chamber, and the outer shell 12 is connected to the outer edges of the bottom plate 111 and the vertical plate 112.

[0045] In this embodiment, a combined structure design of a vertical plate 112 and a shell member 12 is adopted. Compared with a full-coverage structure of the shell member 12, the amount of the shell member 12 is reduced while ensuring the strength of the lamp holder assembly 1, thereby reducing costs and weight. In addition, the assembly structure is simple, and installation, maintenance, and disassembly are convenient.

[0046] Further, such as Figure 2 , 3 As shown, the oscillating head bracket 21 has a U-shaped structure, the U-shaped bottom of the oscillating head bracket 21 is connected to the connecting wheel 32, and the two ends of the U are respectively provided with a rotating shaft 30. The rotating shaft 30 is rotatably connected to the oscillating head bracket 21 through a second bearing 40. One end of the rotating shaft 30 is connected to the lamp body assembly 2, and the other end is connected to the angle adjustment mechanism 4.

[0047] Further, such as Figure 2 As shown, in order to achieve highly reliable shaking head drive of the lamp body assembly 2, the angle adjustment mechanism 4 includes a shaking head driver 41, a second main synchronous pulley 42, a second slave synchronous pulley 43 and a second transmission synchronous belt 44, the shaking head driver 41 is connected to the shaking head bracket 21, and the driving end is connected to the second main synchronous pulley 42, the second slave synchronous pulley 43 is connected to the rotating shaft 30, and the two ends of the second transmission synchronous belt 44 are respectively meshed and connected with the second main synchronous pulley 42 and the second slave synchronous pulley 43.

[0048] In this embodiment, in order to reduce the volume, the second main synchronous pulley 42 and the second slave synchronous pulley 43 are eccentrically arranged, so that the angle adjustment mechanism 4 is arranged as a whole on the side of the oscillating bracket 21 .

[0049] Further, such as Figure 2 , 3 As shown, the lamp body assembly 2 also includes a lamp holder 22 and a light source 23 arranged on the lamp holder 22 .

The focusing lens 24 is a Fresnel lens and is arranged on the lamp holder 22 .

[0051] Furthermore, the light source 23 is an RGBW four-color LED, and the surface of the RGBW four-color LED is not covered with a protective layer of epoxy or glass sheet.

[0052] In this embodiment, since the surface of the RGBW four-color LED is set as a protective layer of glue or glass sheet, although it can prevent the LED from being damaged by touching during the production or assembly process, the protective layer will cause stray light to exist around the effective light spot during the optical projection process of the light source 23. Therefore, by removing the protective layer, the cleanliness of the light spot can be improved, thereby improving the effect and brightness of the light projection.

[0053] Further, such as Figure 3As shown, in order to improve the utilization rate of light and ensure the clarity of the projected light beam, the lamp holder 22 is provided with a focusing assembly 6 between the light source 23 and the focusing lens 24 .

[0054] Further, such as Figure 3 As shown, in order to achieve reliable focus control and improve the beam focusing effect, the focus assembly 6 includes a focus bracket 61, a guide rod 62, a focus lens 63 and a focus driver 64;

[0055] The focusing lens 63 is arranged on the light-through hole of the focusing bracket 61, the guide rod 62 is connected to the lamp holder 22, the focusing bracket 61 is slidably sleeved with the guide rod 62, the focusing driver 64 is connected to the lamp holder 22, and a threaded rod 65 is arranged at the driving end, and the other end of the threaded rod 65 is threadedly connected to the focusing bracket 61.

[0056] In this embodiment, in order to reduce the volume of the lamp body assembly 2 , the internal space of the lamp body assembly 2 is utilized so that the light source 23 , the focusing assembly 6 and the condenser lens 24 are centrally arranged in the lamp frame 22 .

[0057] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the scope of protection of the claims of the utility model patent.
