Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to an optical component and a track spotlight equipped with the optical component, including a lighting system for the track spotlight. Background Technology

[0002] Track spotlights are favored by consumers for their strong directional lighting, good focusing, low energy consumption, long service life, and novel appearance. Existing track spotlights include a lamp body, light source, light source mounting bracket, lens, anti-glare ring, etc. When the light source is installed onto the lamp body, it needs to be fixed to the lamp body using the light source mounting bracket, and then the light source mounting bracket is fixed to the lamp body using bolts. In addition, the light source mounting bracket has positioning holes, and the small-diameter end of the lens has positioning posts. When the lens is installed into the lamp body, the positioning posts on the lens need to be inserted into the positioning holes on the light source mounting bracket. Then, the anti-glare ring is assembled onto the lamp body, pressing the lens firmly against it, thus cooperating with the light source mounting bracket to clamp and fix the lens. However, the assembly of components in existing track equipment has the following shortcomings:

[0003] First, due to the limited internal space of the lamp body, the alignment between the positioning post on the lens and the positioning hole on the light source pressing component cannot be observed during the assembly of the lens and the light source pressing component, which increases the difficulty of alignment; and due to the structural limitations of the lens, the positioning post on the lens is small in size. Therefore, after the positioning post is inserted into the positioning hole, the positioning post will detach from the positioning hole if the lens and / or the lamp body moves slightly, which increases the assembly difficulty.

[0004] Secondly, the assembled light source fixture, lens, and anti-glare ring are stacked and fixed sequentially in the depth direction of the lamp cavity. That is, the lens is pressed and fixed on the light source fixture by the anti-glare ring. Therefore, the tolerance requirements are very high, which can easily cause the lens to loosen or even fall off due to excessive cumulative tolerance, thereby affecting the light output effect and lighting quality of the track spotlight.

[0005] Third, the anti-glare ring is usually directly fastened to the lamp body by a snap-fit ​​connection. However, the lamp body is usually made of aluminum alloy, which means that the lamp body needs to be machined later to form a structure (such as a groove) that matches and connects with the anti-glare ring. This further increases the process cost and reduces production efficiency. Summary of the Invention

[0006] To address the aforementioned problems, the main objective of this invention is to provide an optical component that is easy to assemble, has high assembly reliability, and can reduce production costs.

[0007] Another objective of this invention is to provide a lamp equipped with the aforementioned optical components.

[0008] Another object of this utility model is to provide a lighting system equipped with the above-mentioned lamps.

[0009] To achieve the main objective of this utility model, it provides an optical component, including a lens and an anti-glare ring. The anti-glare ring has a first engaging structure. The optical component also includes a light source holder with a cup cavity. The bottom diameter of the cup cavity is smaller than the opening diameter of the cup cavity. The bottom wall of the cup cavity has a through-hole and a light source port. The lens is installed inside the cup cavity. An elastic limiting strip is formed at the opening of the cup cavity on the light source holder. The two ends of the elastic limiting strip are connected to the light source holder. The elastic limiting strip has a locked position and an unlocked position. When the elastic limiting strip is in the locked position, it covers the lens. When the elastic limiting strip is in the unlocked position, it is located on the outer periphery of the lens. A second engaging structure is formed at the outer periphery of the opening on the light source holder. The anti-glare ring covers the opening, and the second engaging structure is engaged with the first engaging structure.

[0010] As can be seen from the above, by setting the light source clamping component, the light source can be fixed to the lamp body simultaneously when it is installed on the lamp body; the elastic limiting strip on the light source clamping component can realize the quick assembly and disassembly of the light source clamping component and the lens; the second locking structure on the light source clamping component is used to connect with the first locking structure on the anti-glare ring to realize the quick assembly and disassembly of the light source clamping component and the anti-glare ring. Through the structural design of the optical components, the assembly of the lamp is simpler and more convenient, and the lamp body does not need to undergo subsequent machining, effectively reducing production costs and improving production efficiency.

[0011] A further design involves forming a recessed groove at the opening of the light source pressing component. The recessed groove is located between the cup cavity and the elastic limiting strip, and a clamping position is formed between the elastic limiting strip in the locked position and the recessed groove. An eave is formed on the outer periphery of the large-diameter end of the lens, and the eave is located within the clamping position.

[0012] As can be seen from the above, this design is beneficial for fixing the lens to the light source fixture, while also allowing a gap to be left between the lens and the bottom of the cup cavity, and eliminating the need for a tight fit between the lens and the bottom and wall of the cup cavity, thereby reducing the production precision requirements, production difficulty and production cost of the light source fixture and the lens.

[0013] A preferred embodiment is that the eaves have a first notch that penetrates through itself; the cavity wall of the cup cavity has a second notch that penetrates through itself near the elastic limiting strip, and the second notch is connected to the first notch.

[0014] A further design is that the first notch includes a first aperture segment and a second aperture segment, with a step-like structure between the first aperture segment and the second aperture segment; in the depth direction of the cup cavity, the projection of the second aperture segment is located within the projection of the first aperture segment, and the second aperture segment is located between the first aperture segment and the small-diameter end of the lens.

[0015] As can be seen from the above, the design facilitates the control of the elastic limit bar switching from the locked position to the unlocked position, thereby making it easier to remove the lens from the cup cavity.

[0016] Another preferred embodiment is that the bottom wall and the wall of the cup cavity are both formed with a first wiring groove, and the first wiring groove is connected to the light source port.

[0017] As can be seen from the above, this design facilitates the routing of cables connected to the light source and allows for the securing of the cables.

[0018] A further design is that the small-diameter end of the lens is formed with a second wiring groove, which forms a wiring channel with the first wiring groove; the eaves is formed with a third engaging structure, and the recessed groove and / or the cup cavity is formed with a fourth engaging structure that engages with the third engaging structure; one of the third engaging structure and the fourth engaging structure is a first locking block and the other is a first locking groove.

[0019] As can be seen from the above, the design of the second wiring slot on the lens is more conducive to the routing of cables connected to the light source, so as to avoid the lens squeezing the cables; while the design of the third locking structure on the lens and the fourth locking structure on the light source pressing component can play a foolproof role, ensuring that the second wiring slot and the first wiring slot form a wiring channel, and at the same time, it is convenient to quickly align and assemble the lens and the light source pressing component.

[0020] Another preferred embodiment is that the anti-glare ring is also formed with a pressure block and a fifth engagement structure, the pressure block is in contact with the eaves, and the light source pressure piece is also formed with a sixth engagement structure that engages with the fifth engagement structure; one of the fifth engagement structure and the sixth engagement structure is a second locking block and the other is a second locking groove; one of the first engagement structure and the second engagement structure is a buckle and the other is a third locking groove.

[0021] As can be seen from the above, the design of the pressure block on the anti-glare ring allows the anti-glare ring to work with the recessed groove to assist in pressing and fixing the lens. At the same time, it also creates a clearance space between the anti-glare ring and the lens to avoid the elastic limiting strip, thereby preventing unreasonable compression of the elastic limiting strip.

[0022] A further design involves forming a light source limiting groove and a positioning foot on the bottom wall of the cup cavity, both of which are located outside the cup cavity.

[0023] As can be seen from the above, the light source limiting groove is used to accommodate the light source and limit its position, so that the light source is stably and reliably fixed between the lamp body and the light source holder, thereby allowing the light-emitting end of the light source to be closer to the lens to ensure the light output effect of the light source; while the design of the positioning foot enables the light source holder and the lamp body to be quickly positioned when they are assembled, and also plays a role in preventing mistake during the assembly of the two.

[0024] To achieve another objective of this utility model, this utility model provides a track spotlight, including a light source module and a lamp body. The lamp body has a lamp cavity, and the track spotlight also includes the aforementioned optical components. The light source clamp is connected to the bottom of the lamp cavity through a connecting hole, and the light source is pressed and fixed between the light source clamp and the bottom of the lamp cavity. The light-emitting end of the light source is located inside the light source opening.

[0025] As can be seen from the above, the track spotlight equipped with the aforementioned optical components is simpler and more convenient to assemble, and eliminates the need for subsequent machining of the lamp body, effectively reducing production costs and improving production efficiency.

[0026] To achieve another objective of this utility model, this utility model provides a lighting system, which includes the track spotlights as described above.

[0027] As can be seen from the above, by installing the aforementioned track spotlights, the lighting system has the advantages of good lighting effect, high safety and low operating cost. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0036] Optical component embodiment

[0037] Reference Figure 1 and Figure 2The optical component 100 includes a light source clamping element 1, a lens 2, and an anti-glare ring 3. The light source clamping element 1 is used to connect to the lamp body of the lamp and, together with the lamp body, presses and fixes the light source 10 onto the lamp body. At the same time, the lens 2 and the anti-glare ring 3 are directly and detachably connected to the light source clamping element 1, making the installation of the lens 2 simpler and more convenient. There is no need to set a positioning post on the lens 2, and there is no need to worry about the lens 2 shifting or misaligning during or after assembly. There is also no assembly tolerance between the lens 2 and the anti-glare ring 3, thus solving the problem of the lens 2 loosening or falling off after assembly due to the cumulative tolerance of the light source clamping element 1, the lens 2, and the anti-glare ring 3. In addition, there is no need for subsequent machining of the lamp body, thereby effectively reducing production costs and improving production efficiency.

[0038] Combination Figures 3 to 5 The light source clamping component 1 has a cup cavity 11, which is approximately frustum-shaped, and the bottom diameter of the cup cavity 11 is smaller than the open diameter of the cup cavity 11. The bottom wall of the cup cavity 11 is formed with a connecting hole 111 and a light source opening 112, which penetrate the bottom wall of the cup cavity 11 in the depth direction. The connecting hole 111 allows the light source clamping component 1 to be connected to the lamp body by bolts passing through the connecting hole 111 and connecting to the corresponding connecting hole 111 on the lamp body during assembly, thereby fixing the light source clamping component 1 to the lamp body and clamping the light source 10 of the lamp between the light source clamping component 1 and the lamp body.

[0039] Preferably, a light source limiting groove 113 and a positioning foot 114 are also formed on the bottom wall of the cup cavity 11. Both the light source limiting groove 113 and the positioning foot 114 are located outside the cup cavity 11, that is, the light source limiting groove 113 and the positioning foot 114 are formed on the side of the bottom wall of the cup cavity 11 facing the light source 10. The light source opening 112 avoids the light-emitting end 101 of the light source 10 of the lamp, so that the light emitted by the light-emitting end 101 can enter the lamp cavity. The light source limiting groove 113 is used to accommodate the light source 10 and limit the light source 10, so that the light source 10 is stably and reliably fixed between the lamp body and the light source pressing component 1 of the lamp, and so that the light-emitting end 101 of the light source 10 can be closer to the lens 2 to ensure the light output effect of the light source 10. The positioning foot 114 can quickly position the light source pressing component 1 and the lamp body when they are assembled, and also plays a role in preventing mistaken assembly.

[0040] Furthermore, an elastic limiting strip 12 is formed at the opening of the cup cavity 11 of the light source pressing component 1. Both ends of the elastic limiting strip 12 are connected to the light source pressing component 1, and the elastic limiting strip 12 can elastically deform. The elastic limiting strip 12 has a locking position (e.g., Figure 5 The blue solid line indicates the position of the elastic limit bar 12 and the unlocking position (e.g., Figure 5(The position of the elastic limiting strip 12 is shown by the red dashed line). When the elastic limiting strip 12 is in the locked position, in the depth direction of the cup cavity 11, a portion of the projection of the elastic limiting strip 12 is located within the projection of the opening of the cup cavity 11; when the elastic limiting strip 12 is in the unlocked position, in the depth direction of the cup cavity 11, the projection of the elastic limiting strip 12 overlaps with the outer contour projection of the opening of the cup cavity 11 or is located outside the outer contour projection of the opening of the cup cavity 11.

[0041] Combination Figure 6 Lens 2 is detachably installed within the cup cavity 11. During the installation of lens 2 into the cup cavity 11, when lens 2 passes the elastic limiting strip 12, lens 2 forces the elastic limiting strip 12 to switch from the locked position to the unlocked position. At this time, the elastic limiting strip 12 in the unlocked position is located on the outer periphery of lens 2. When lens 2 continues to be inserted into the cup cavity 11 and passes the elastic limiting strip 12, the elastic limiting strip 12 switches from the unlocked position to the locked position under its own elastic potential energy, and then the elastic limiting strip 12 covers lens 2. Preferably, when the elastic limiting strip 12 is in the locked position, the elastic limiting strip 12 is adjacent to lens 2 to better press and fix lens 2 within the cup cavity 11. The cup cavity 11 is designed to reflect the light emitted by the light source 10 of the lamp back to lens 2, thereby improving the light output effect of the light source 10. The design of the elastic limiting strip 12 facilitates the rapid assembly of the lens 2 and the light source clamping component 1, thereby improving assembly efficiency and ensuring the reliability of the lens 2 being clamped and fixed, preventing the lens 2 from loosening or falling off after assembly.

[0042] Furthermore, the light source clamping component 1 also has a recessed groove 13 formed at the opening of the cup cavity 11. The recessed groove 13 is located between the opening of the cup cavity 11 and the elastic limiting strip 12, so that the elastic limiting strip 12 in the locked position and the bottom of the recessed groove 13 can form a clamping position. Correspondingly, the outer periphery of the large-diameter end of the lens 2 is formed with an eave 21. When the lens 2 is installed on the light source clamping component 1, the main body of the lens 2 is located in the cup cavity 11, while the eave 21 of the lens 2 is located in the clamping position, so that the light source clamping component 1 clamps and fixes the lens 2 through the clamping position and the eave 21. Preferably, when the eave 21 is in the clamping position, the eave 21 is adjacent to the bottom of the recessed groove 13 and the elastic limiting strip 12, thereby reducing the possibility of the assembled lens 2 moving around. The recessed groove 13 at the opening of the cup cavity 11 cooperates with the elastic limiting member, and the eaves 21 is provided on the lens 2. This is beneficial for fixing the lens 2 to the light source pressing member 1. At the same time, it allows a gap to be left between the lens 2 and the bottom of the cup cavity 11, and eliminates the need for the lens 2 to be tightly fitted to the bottom and cavity wall of the cup cavity 11. This reduces the production precision requirements, production difficulty and production cost of the light source pressing member 1 and the lens 2.

[0043] To ensure that the elastic limiting strip 12 can reliably press and fix the lens 2, the number of elastic limiting strips 12 is preferably two to four, and the two to four elastic limiting strips 12 are evenly distributed along the circumference of the cup cavity 11. For example, in this embodiment, the number of elastic limiting strips 12 is three.

[0044] To facilitate the switching of the elastic limiting strip 12 from the locked position to the unlocked position, and to make it easier to remove the lens 2 from the cup cavity 11, a first notch 22 can be formed on the rim 21 of the lens 2, and the first notch 22 penetrates the rim 21 in the depth direction of the cup cavity 11; correspondingly, a second notch 115 is formed on the cavity wall of the cup cavity 11 near the elastic limiting strip 12, and the second notch 115 penetrates the cavity wall. Preferably, the first notch 22 includes a first hole segment 221 and a second hole segment 222, and the first hole segment 221 and the second hole segment 222 are stepped; wherein, in the depth direction of the cup cavity 11, the projection of the second hole segment 222 is located within the projection of the first hole segment 221, and the second hole segment 222 is located between the first hole segment 221 and the small-diameter end of the lens 2.

[0045] Furthermore, the light source clamping component 1 has a first wiring groove 14 formed on the bottom wall and the cavity wall near the bottom wall of the cup cavity 11. The first wiring groove 14 communicates with the light source port 112. The design of the first wiring groove 14 facilitates the routing of cables connected to the light source 10 of the lamp and fixes the cables. Preferably, the small-diameter end of the lens 2 has a second wiring groove 23 formed, and the second wiring groove 23 and the first wiring groove 14 form a wiring channel. The setting of the second wiring groove 23 is more conducive to the routing of cables connected to the light source 10, so as to avoid the lens 2 squeezing the cables.

[0046] Furthermore, the eaves 21 is formed with a third engaging structure 211, and the recessed groove 13 and / or the cup cavity 11 are formed with a fourth engaging structure 116 that engages with the third engaging structure 211; wherein, one of the third engaging structure 211 and the fourth engaging structure 116 is a first engaging block and the other is a first engaging groove. In this embodiment, the third engaging structure 211 is the first engaging block, and the fourth engaging structure 116 is the first engaging groove. The first engaging groove is formed in the cup cavity 11, and the opening of the first engaging groove is formed on the bottom wall of the recessed groove 13. The design of the third engaging structure 211 on the lens 2 and the fourth engaging structure 116 on the light source pressing component 1 can play a foolproof role, ensuring that the second wiring groove 23 and the first wiring groove 14 form a wiring channel, and at the same time, it facilitates the quick alignment and assembly of the lens 2 and the light source pressing component 1.

[0047] Combination Figure 7The anti-glare ring 3 is provided with a first engaging structure 31, and the light source pressing component 1 has a second engaging structure 15 formed on the outer periphery of the opening. When the anti-glare ring 3 is assembled with the light source pressing component 1, the anti-glare ring 3 covers the opening of the cup cavity 11, and the second engaging structure 15 is engaged with the first engaging structure 31. One of the first engaging structure 31 and the second engaging structure 15 is a buckle, and the other is a third locking groove. To ensure the firmness of the assembly between the anti-glare ring 3 and the light source pressing component 1, the number of the first engaging structure 31 and the second engaging structure 15 is preferably two to four, and the two to four first engaging structures 31 are evenly distributed along the circumference of the anti-glare ring 3, and the two to four second engaging structures 15 are evenly distributed along the circumference of the cup cavity 11. In this embodiment, the first engaging structure 31 is a buckle, and the second engaging structure 15 is a third locking groove; the number of the first engaging structure 31 and the second engaging structure 15 is three.

[0048] Preferably, the anti-glare ring 3 is also formed with a pressure block 32 and a fifth engagement structure 33. The pressure block 32 is used to contact the rim 21 of the lens 2. The number of pressure blocks 32 is preferably equal to the number of elastic limiting strips 12, and the pressure blocks 32 and elastic limiting strips 12 are distributed alternately. The design of the pressure block 32 allows the anti-glare ring 3 to cooperate with the recessed groove 13 to assist in pressing and fixing the lens 2. At the same time, it also creates a clearance space between the anti-glare ring 3 and the lens 2 to avoid the elastic limiting strips 12, thereby avoiding unreasonable compression of the elastic limiting strips 12. In addition, a sixth engaging structure 16 is formed on the light source pressing component 1. When the anti-glare ring 3 is assembled with the light source pressing component 1, the sixth engaging structure 16 engages with the fifth engaging structure 33. Among them, one of the fifth engaging structure 33 and the sixth engaging structure 16 is a second locking block and the other is a second locking groove. For example, in this embodiment, the fifth engaging structure 33 is the second locking block and the sixth engaging structure 16 is the second locking groove.

[0049] In summary, the structural design of the optical component 100 makes the assembly of the optical component 100 with the lamp body simpler and more convenient, and ensures the assembly reliability between various components, between the optical component 100 and the lamp body and light source 10, preventing the lens 2 from loosening or falling off after assembly, and also helps to reduce production costs.
