Description

Technical Field

[0001] This utility model relates to the field of lighting source technology, specifically to a split adjustable three-dimensional light source. Background Technology

[0002] Currently, traditional three-dimensional light sources mostly adopt a one-piece fixed structure, which cannot flexibly adjust the position of the light source, resulting in limitations on the illumination angle and range. Especially in scenarios requiring dual-light source coordinated illumination, it is difficult to achieve flexible adjustment of light field uniformity and coverage. In addition, the heat dissipation path of the one-piece design is singular. Some solutions introduce fans for forced cooling, but this increases noise, vibration, and power consumption, affecting the use of automated equipment.

[0003] Therefore, a new type of three-dimensional light source is urgently needed to solve the above problems. Utility Model Content

[0035] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; "connection" can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] See Figures 1 to 7 This utility model provides a split-type adjustable three-dimensional light source, including: an adjustment mechanism 300 and two light source units arranged side by side and opposite to each other; wherein,

[0040] The light source unit is a three-dimensional light source that emits light from one side, and the two light source units emit light in the same direction; the light source unit is electrically connected to an external light source controller via electrical connection line 2 to supply power to the light source unit;

[0041] The adjustment mechanism 300 is provided with an adjustment part, and at least one of the light source units is slidably disposed on the adjustment part so that the relative position of the two light source units can be adjusted.

[0042] Specifically, the light source unit includes a base 3, an LED light source array 8 disposed within the base 3, and a diffuser 9 covering the LED light source array 8; the diffuser 9 forms a light-emitting surface on the side away from the LED light source array 8, the center of the outline of the light-emitting surface is curved inward with a recess 5, and the side edge of the light-emitting surface forms an arc-shaped recess 4 along the vertical direction of the light-emitting surface.

[0043] The front surface of the light source unit is the emitting surface, with its central area recessed inward to form a smooth arc-shaped surface. The side edges also adopt an arc transition, effectively reducing the edge dark areas when light is scattered. Two U-shaped through slots are symmetrically opened on the emitting surface. The through slots extend in the vertical direction and the openings are parallel to the side edges, further enhancing the light diffusion range and achieving uniform illumination at a large angle.

[0044] Furthermore, the light-emitting surface of the light source unit is U-shaped, and a U-shaped opening 1 is formed between the two arms of the U-shaped light source unit.

[0045] Furthermore, the two light source units are arranged with the same shape and mirror symmetry, and the U-shaped openings 1 of the two U-shaped light source units are set opposite each other.

[0046] The U-shaped channel forms a natural light guide, and the light undergoes multiple diffuse reflections on the inner wall of the channel, resulting in uniform diffuse reflection of the light. At the same time, the U-shaped opening 1 design can increase the contact area between the light source unit and the air, thereby increasing the heat dissipation efficiency.

[0047] Preferably, the adjusting mechanism 300 includes an adjusting rod assembly;

[0048] The adjusting rod assembly includes an adjusting block 35, the adjusting part, and an adjusting rod fixing block 36, wherein the adjusting part is an adjusting rod 31;

[0049] The adjusting rod fixing block 36 is fixed to the first side wall of the non-light-emitting surface of the first light source unit 100. The adjusting block 35 is symmetrically arranged on the corresponding first side wall of the second light source unit 200. The adjusting block 35 has a through sliding hole inside. One end of the adjusting rod 31 is fixedly connected to the adjusting rod fixing block 36, and the other end extends slidably into the sliding hole. The adjusting rod 31 has a limiting protrusion at the free end of the rod body. The radial dimension of the limiting protrusion is larger than the inner diameter of the sliding hole, so that when the adjusting rod 31 slides along the axis of the sliding hole, the stroke is limited by the contact between the limiting protrusion and the end of the sliding hole.

[0050] The diameter of the limiting protrusion at the free end of the adjusting rod 31 is larger than the inner diameter of the sliding through hole. When the adjusting rod 31 slides to its limit position, the protrusion contacts the end face of the through hole, forming a rigid mechanical limit, effectively preventing the adjusting rod 31 from coming off or displacing excessively. In a more preferred embodiment, by replacing the adjusting rod 31 with a longer one, the adjustment range of the light source is expanded, allowing this three-dimensional light source to adapt to the lighting needs of large workpieces.

[0051] More specifically, the adjustment mechanism 300 further includes a locking component; the locking component includes a locking plate 32, the fixed end of which is fixedly disposed on the first side wall of the second light source unit 200 corresponding to the adjustment block 35, and the locking end of the locking plate 32 extends to the first side wall of the first light source unit 100; the locking plate 32 follows the position change of the second light source unit 200 relative to the first light source unit 100, and a positioning groove is provided on the locking end of the locking plate 32, the extension direction of which is parallel to the axial direction of the rod body of the adjustment rod 31, and the locking end is used to lock and position with the first side wall of the first light source unit 100.

[0052] Preferably, the locking assembly further includes a fastening assembly, which includes several first threaded holes (not labeled in the figure), second threaded holes (not labeled in the figure), a first screw 33, and a second screw 34. The first threaded holes are formed on the first light source unit 100 and multiple first threaded holes are formed within the active stroke of the positioning groove. The first screw 33 passes through the positioning groove and is screwed into the first threaded hole to fasten the locking plate 32. The second threaded hole is provided on the adjusting block 35, and the central axis of the second threaded hole is perpendicular to the axis of the adjusting rod 31. The second screw 34 is screwed into it to fasten the adjusting rod 31.

[0053] When using the device, after adjusting the two light sources to a suitable distance, the user inserts the first screw 33 through the positioning groove and locks it in place. The first screw 33 can be a head screw, cup screw, or other type of screw, and can be used with spring washers and flat washers to secure the locking plate 32. After the positioning plate is locked, the second screw 34 is screwed into the second threaded hole. The second screw 34 can be a stop screw to lock the adjusting rod 31. If the user needs to adjust the distance between the light sources again, the user can manually adjust the distance by tightening the first screw 33 and the second screw 34. With the fastening and locking components set up as described above, the user can efficiently complete the adjustment, locking, and maintenance of the light sources, ensuring the long-term stable operation of the equipment.

[0054] Furthermore, the base 3 includes an aluminum substrate 7 and a heat dissipation adhesive coating, the LED light source array 8 is disposed on the aluminum substrate 7, and the heat dissipation adhesive coating is disposed on the aluminum substrate 7.

[0055] The aluminum substrate 7 serves as the direct carrier of the LED light source, rapidly dissipating the heat generated by the LED light source. The heat dissipation adhesive coating fills the air gap between the aluminum substrate 7 and the housing, allowing the heat in the aluminum substrate 7 to be transferred to the housing, which then transfers the heat to the air. At the same time, the rigidity of the aluminum substrate 7 ensures the positional accuracy of the LED light source and maintains the uniformity of the light field.

[0056] Preferably, the aluminum substrate 7 is an aluminum plate whose shape matches the contour of the diffuser 9, and the LED light source array 8 is arranged in a ring array around the U-shaped opening 1.

[0057] The LED light source array 8 has a high density of LED beads near the center of the U-shaped opening, corresponding to the deepest area of ​​the concave surface. This increases the light refraction angle and disperses the light intensity. The outermost LED beads have a lower density, and the concave surface curvature is flatter, reducing light loss and achieving a smooth transition of the illuminance gradient. This results in uniform light distribution and reduces blind spots.

[0058] Specifically, there are two sets of adjustment mechanisms 300, which are symmetrically arranged on the light source unit, and the two sets of adjustment mechanisms are respectively arranged on both sides of the two light source units.

[0059] Two sets of adjusting rod assemblies act synchronously on both sides of the light source unit, eliminating the deflection torque caused by unilateral force application and ensuring that the light source translates along a straight trajectory. Simultaneously, the inclusion of two adjusting mechanisms 300 increases reliability during use. It should be understood that the above description of specific embodiments of this utility model is merely to illustrate the technical route and features of this utility model, and its purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. However, this utility model is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of this utility model should be covered within the protection scope of this utility model.
