[0002] Traditional LED wire support structures are mostly formed by injection molding a silver-plated or gold-plated mirror wire frame with white reflective plastic to form a cup body to achieve the effect of focusing and reflecting.

[0003] However, in the above-mentioned cup body, the mirror reflective surface is only the bottom surface of the cup body, so it can only achieve the effect of upward reflection; and although reflective powder is added to the side wall of the lamp cup, its reflected light type is diffuse reflection, and the light brightness brought by diffuse reflection is not as good as that of mirror reflection. Therefore, the side wall of the cup body cannot effectively control the "light output angle" and "luminous flux density", and it also causes the loss of part of the light energy, which in turn causes the light brightness to be not high enough.

In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0028] Example 1

[0029] like Figure 1-Figure 6 A bracket capable of adjusting the light output angle and the light flux density comprises a bracket body 1, a lamp trough 2, a lamp wall 3 and a lampshade 4. When in use, the position of the bracket body 1 is fixed first. A card slot is provided on the bracket body 1. Card blocks are fixed on both sides of the lampshade 4. The card blocks and the card slots are snap-fitted and connected.

[0030] The bracket body 1 is also provided with a lamp slot 2 for placing lamp beads. The lamp slot 2 is arranged within the range of the cover of the lampshade 4. The lamp beads are connected in series with the mains through an external controller, and the external controller is used to control the on and off state of the lamp beads.

[0031] The bracket body 1 is provided with an angle adjustment slot, and an L-shaped lamp wall 3 is fixed on the side wall of the angle adjustment slot.

[0032] During actual production, the lamp wall 3 is formed by punching on the bracket body 1 by a punching machine.

[0033] Furthermore, the support body 1 and the lamp wall 3 are both made of mirror material. Preferably, the support body 1 and the lamp wall 3 are both made of metal. The energy loss rate of the light reflected to the outside through the mirror is lower, so the light brightness is more sufficient.

[0034] A design form of the lamp wall 3 : the openings of two L-shaped lamp walls 3 are designed to face each other to form a bowl shape, and the lamp trough 2 is located in the middle of the two lamp walls 3 .

[0035] The mirror metal bracket body 1 is bent or stretched to the calculated and designed angle to be formed into a "bowl shape" with the mirror reflection surface "facing inward", thereby focusing the light emitted by the lamp beads inward through the mirror reflection surface, and utilizing the angle between the bracket body 1 and the lamp wall 3 to effectively achieve the effect of "adjusting the light flux density" to reduce energy loss. Through the "focusing" effect, this design can increase the central light intensity by more than 25%.

[0036] Based on the "bowl-shaped" angle design of the lamp wall 3, the luminous flux density, that is, the light output intensity, can be effectively improved compared to the "same type" traditional bracket body 1, and the luminous flux density can be adjusted by adjusting the molding angle of the lamp wall 3. Therefore, it is more conducive to the design of "secondary optics-optical lens" to achieve a two-way matching and adjustment design to obtain the most ideal light output effect.

[0037] With this design, the secondary optical improvement can reach 5%-10% efficiency.

[0038] Another design form of the lamp wall 3 is that the openings of the two L-shaped lamp walls 3 are designed back to back, and a lamp groove 2 is arranged on the opening side of each lamp wall 3 .

[0039] The middle of the metal bracket body 1 is bent or stretched to form a mirror reflective lamp wall 3. The angle of the bevel formed by the lamp wall 3 is the angle designed and calculated according to the optical requirements. The natural angle of the light emitted by the lamp bead is 120°, but the angle of the mirror lamp wall 3 is designed to refract the light to the designed and expected positions on both sides, so that the original 120° light emission can be further increased, and it is expected to achieve more than 160°, and the light emission angle is increased by more than 30%. This can improve and optimize the light emission effect, and its effects are:

[0040] 1. Increasing the light mixing area between lamp beads can improve the uniformity of light output.

[0041] 2. Increasing the distance between lamp beads can effectively reduce the number of LED lamp beads to achieve the effect of reducing costs.

[0042] Therefore, by utilizing the above design, the effect of “effectively adjusting the light output angle” can be effectively achieved.

[0043] In the design of the lamp wall 3 described above, the light emitted by the lamp beads can all be irradiated onto the lamp wall 3 , and the light is reflected and refracted toward the outside due to the reflection effect of the lamp wall 3 .

[0044] Example 2

[0045] like Figure 5-Figure 7 On the basis of Example 1, the purpose of fine-tuning the lighting angle is achieved by adding a bottom plate 5, a top block 6 and a connecting piece 7. Specifically, the bracket body 1 and the bottom plate 5 are connected by a damping sliding connection, and the top block 6 is fixed on the bottom plate 5. The connecting piece 7 is used to fine-adjust the distance between the bracket body 1 and the bottom plate 5. When the distance between the two is reduced, the top block 6 passes through the angle adjustment groove and is squeezed onto the corresponding lamp wall 3. The lamp wall 3 is driven to rotate relative to the bracket body 1 by the squeezing force, thereby fine-adjusting the angle between the bracket body 1 and the lamp wall 3, so as to achieve the adjustment of the path of the light reflected through the lamp wall 3.

[0046] The connection point between the bracket body 1 and the lamp wall 3 is rotatable. Metal has certain deformation characteristics. When the bracket body 1 and the lamp wall 3 are made of metal sheets, it is more in line with the above-mentioned movement basis.

[0047] In one case of this embodiment, the connecting member 7 is a bolt, which passes through the base plate 5 and is threadedly connected to the base plate 5. The turning pin passes through the bracket body 1 and is fixedly connected to the bolt. The turning pin can rotate freely in the bracket body 1, and the end of the bolt conflicts with the bracket body 1. When the bolt is tightened, the bolt drives the bracket body 1 and the base plate 5 to approach each other, and allows the top block 6 to squeeze the corresponding lamp wall 3. A thread with a self-locking angle can be selected. When the user removes the external force, the stability of the bolt position can be guaranteed. However, in this case, the user cannot remember the actual number of turns of each bolt during operation, so the following improvements are made.

[0048] In another situation of this embodiment, the connecting member 7 includes a corrugated block 71, a bolt cap 72, an insert rod 73, and a connecting rod 74. Several sections of the corrugated block 71 are connected in sequence along the axial direction of the corrugated block 71 to form a rod body with a wavy side surface, and one end of the rod body is fixedly connected to the bolt cap 72.

[0049] Among them, the corrugated block 71 includes a crest section and a trough section. Taking the cross-section of the corrugated block 71 as an example, the crest section refers to the part with the largest cross-sectional diameter of the corrugated block 71, and the trough section refers to the part with the smallest cross-sectional diameter of the corrugated block 71. The crest section and the trough section of the entire rod body have a smooth transition and are arranged in an alternating manner.

[0050] Corrugated holes are provided at corresponding positions of the bracket body 1 and the bottom plate 5 . The shapes of the corrugated holes and the corrugated blocks 71 correspond to each other, that is, each corrugated block 71 can be stably inserted into the corrugated hole.

[0051] Preferably, the corrugated holes on the bracket body 1 are designed as blind holes, and the corrugated holes on the bottom plate 5 are designed as through holes.

[0052] Because the number of corrugated blocks 71 is relatively intuitive, it is possible to artificially balance the distance between the bracket body 1 and the base plate 5 by observing which corrugated block 71 among several connecting members 7 is stuck in the corrugated hole. When in use, the corrugated blocks 71 on the connecting members 7 are respectively stuck in the corrugated holes of the bracket body 1 and the base plate 5.

[0053] Furthermore, a cavity is opened in the corrugated block 71, and a rod 73 is inserted in the cavity. The rod 73 is a prism, and the rod 73 and the bolt cap 72 are slidably connected. The rod 73 and the peak section of the corrugated block 71 are flexibly connected by a connecting rod 74. By pulling the rod 73 out of the bolt cap 72, the inclination angle of the connecting rod 74 becomes larger, and the force of the connecting rod 74 used to support the corrugated block 71 is changed, and the bolt cap 72 is completely pushed into the cavity, and the inclination angle of the gradually horizontal connecting rod 74 becomes smaller, so that the connecting rod 74 supports the peak section.

[0054] It should be noted that the snap-fitting characteristics of the corrugated block 71 and the corrugated hole itself require that the corrugated block 71 and the corrugated hole have a certain degree of deformation ability, so that each section of the corrugated block 71 can be inserted into or pulled out of the corrugated hole by human power.

[0055] At the same time, the two ends of the connecting rod 74 are connected to the corrugated block 71 and the plug rod 73 through the bendable rod ends, and the connecting rod 74 itself is relatively rigid and not easy to bend. Therefore, when the plug rod 73 is pulled out from the bolt cap 72, the peak section of the corrugated block 71 will be deformed, making it easier for the corrugated block 71 to be pulled out of the corrugated hole. When the position of the connecting piece 7 needs to be fixed, the plug rod 73 is inserted into the corrugated block 71, so that the gradually horizontal connecting rod 74 supports the peak section, thereby improving the stability of the corrugated block 71 in the corrugated hole.

[0056] Preferably, the material of the corrugated block 71 can be rubber.

[0057] Preferably, the connection between the insertion rod 73 and the bolt cap 72 can be a snap connection or a damping connection to improve the stability of the connection between the two.

[0058] Preferably, the outer end surface area of ​​the insertion rod 73 is larger than the bolt cap 72 , so that the user can easily pick up the insertion rod 73 to separate the insertion rod 73 and the bolt cap 72 .

[0059] In summary, the improvements of this application are mainly:

[0060] The traditional bracket body 1 is improved and optimized in design, that is, the "silver-plated mirror metal material" is subjected to "sheet metal stamping forming". By utilizing the forming of the metal and the refractive and reflective properties of the mirror, it can be formed at an angle through "calculation and design" to effectively control the light output angle and luminous flux density, so as to obtain the best utilization of the expected "light output effect".
