Description

Technical Field

[0001] This utility model is a multi-optical lens assembly, belonging to the field of lighting technology. Background Technology

[0002] Currently, the combination of a single lens and a reflector is widely used in lighting fixtures. Although this method is technically mature, it also has some inherent defects and limitations. For example, the combination of a single lens and a reflector has relatively limited optical path design and light control capabilities. There are often areas where light is not effectively collected or controlled and is lost, which reduces the overall light efficiency. Therefore, how to provide a multi-optical lens assembly to enhance the overall light efficiency of lighting fixtures is an urgent problem to be solved. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-optical lens assembly.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A multi-optical lens assembly includes a reflector, a lamp plate, and a lens plate. The lamp plate and the lens plate are located on opposite sides of the reflector. The reflector has a lens hole and a light guide hole. The lamp plate is equipped with a main LED bead that mates with the lens hole, several first auxiliary LED beads, and several second LED beads that mate with the light guide hole. The lens plate is connected to a Fresnel optical lens, a TIR lens, and a light guide post via a connecting mechanism. The Fresnel optical lens and several TIR lenses are adapted to the lens hole, and the light guide post is adapted to the light guide hole.

[0006] Furthermore, the connecting mechanism includes a mounting hole formed on the side of the lens plate near the reflector cup, an internal thread is formed on the inner sidewall of the mounting hole, a mounting groove is formed at the opening of the mounting hole, and a plurality of damping grooves are provided inside the mounting groove.

[0007] Furthermore, the connecting mechanism also includes an external toothed ring, the external thread of which is adapted to the internal thread, and a plurality of damping positioning blocks are uniformly arranged in the outer edge space of the outer side of the external toothed ring, the damping positioning blocks being adapted to the damping groove.

[0008] Furthermore, several sets of external toothed rings are respectively fixed to the bottom inner walls of the Fresnel optical lens, the TIR lens, and the light guide post, and the outer wall of the external toothed rings to the bottom outer edge of the Fresnel optical lens, the TIR lens, and the light guide post constitutes the outer edge space.

[0009] Furthermore, the mounting hole is either a through hole structure or a non-through groove structure.

[0010] Furthermore, a reflective groove is provided on the side of the reflector cup near the lens plate.

[0011] Furthermore, the reflector cup is provided with several locking posts, and the lamp plate is provided with locking holes that cooperate with the locking posts.

[0012] The beneficial effects of this utility model are:

[0013] This invention, by setting Fresnel optical lenses, TIR lenses and light guide columns, can refract or emit light in the reflector cup area in multiple ways, thereby achieving efficient light focusing and light spot optimization, and improving overall light efficiency.

[0014] Furthermore, the design of the connecting mechanism allows for the installation of Fresnel lenses, TIR lenses, and light guides on the lens plate. This is achieved by fitting the external toothed rings at the bottom of each component (Fresnel lens, TIR lens, and light guide) to the mounting holes on the lens plate, and then securing them using the external toothed rings and internal threads. Simultaneously, the bottom of the lens is installed within the mounting groove, further secured by the threads. The design of the snap-fit ​​posts and snap-fit ​​holes enables the reflector and lamp panel to be quickly and securely fixed together, facilitating rapid lens installation and subsequent replacement and maintenance.

[0015] By designing the damping positioning blocks and the damping grooves, when the bottom of the lens is installed in the mounting groove, several damping positioning blocks on the bottom of the lens will engage with several damping grooves in the mounting groove. Thus, while making a threaded connection, the lens can also be fixed to the lens plate by damping positioning, preventing the lens from rotating and loosening, and further enhancing the installation effect of the lens.

[0016] In addition, the reflective grooves on the side of the reflector cup can enhance the brightness of the lens and create the optical effect of a light guide plate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-11 This utility model provides a multi-optical lens assembly technical solution, including a reflector cup 1, a lamp plate 2, and a lens plate 3. The lamp plate 2 and the lens plate 3 are located on opposite sides of the reflector cup 1. The reflector cup 1 has a lens hole 4 and a light guide hole 5. The lamp plate 2 is equipped with a main LED 6 that cooperates with the lens hole 4, several first auxiliary LEDs 7, and several second LEDs 8 that cooperate with the light guide hole 5. The lens plate 3 is connected to a Fresnel optical lens 10, a TIR lens 11, and a light guide post 12 through a connecting mechanism. The Fresnel optical lens 10 and several TIR lenses 11 are adapted to the lens hole 4, and the light guide post 12 is adapted to the light guide hole 5.

[0032] See Figures 8-11 The connecting mechanism includes a mounting hole 18 on the side of the lens plate 3 near the reflector cup 1. An internal thread 19 is provided on the inner sidewall of the mounting hole 18. A mounting groove 20 is provided at the opening of the mounting hole 18. Several damping grooves 9 are provided inside the mounting groove 20. The connecting mechanism also includes an external gear ring 15. The external thread of the external gear ring 15 is adapted to the internal thread 19. Several damping positioning blocks 17 are evenly arranged in the outer edge space 16 of the outer side of the external gear ring 15. The damping positioning blocks 17 are adapted to the damping grooves 9. Several sets of external gear rings 15 are respectively fixed to the bottom inner walls of the Fresnel optical lens 10, the TIR lens 11, and the light guide post 12. The outer wall of the external gear ring 15 extends to the Fresnel... The outer edges of the bottom of the optical lens 10, the TIR lens 11, and the light guide post 12 are all defined by the outer edge space 16. Through the design of the connecting mechanism, when mounting the Fresnel optical lens 10, the TIR lens 11, and the light guide post 12 on the lens plate 3, the outer toothed ring 15 at the bottom of each of the three components can be adapted to the mounting hole 18 on the lens plate 3, and then threadedly fixed using the outer toothed ring 15 and the internal thread 19. Simultaneously, the bottom of the lens is installed in the mounting groove 20 for further threaded fixation. The mounting hole 18 can be a through hole or a non-through groove structure; the fit is adjusted according to the type of lens, thereby allowing the lens to be connected and fixed to the lens plate 3.

[0033] The reflector cup 1 has a reflective groove (not shown in the figure) on the side near the lens plate 3; the reflective groove on the side of the reflector cup 1 can enhance the brightness of the lens and form the optical effect of a light guide plate.

[0034] See Figure 2 , Figure 3 , Figure 6The reflector cup 1 is provided with several locking posts 13, and the lamp plate 2 is provided with locking holes 14 that cooperate with the locking posts 13. Through the design of the locking posts 13 and locking holes 14, the reflector cup 1 and the lamp plate 2 can be quickly fixed together to form a whole, thereby realizing the quick installation of the lens and facilitating later replacement and maintenance.

[0035] When installing or replacing the Fresnel optical lens 10, TIR lens 11, and light guide post 12 on the lens plate 3, the outer toothed ring 15 at the bottom of the Fresnel optical lens 10, TIR lens 11, and light guide post 12 can be adapted to the mounting hole 18 on the lens plate 3, and then threadedly fixed by the outer toothed ring 15 and the internal thread 19. At the same time as fixing, the bottom of the lens will be installed in the mounting groove 20, and several damping positioning blocks 17 on the bottom of the lens will be engaged in several damping grooves 9 in the mounting groove 20. Thus, while threaded connection is being made, the lens can also be fixed on the lens plate 3 by damping positioning to prevent the lens from rotating and loosening, and further enhance the installation effect of the lens.
