Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an LED lamp and a lighting system provided with the LED lamp. Background Art

[0002] LED lamps are the mainstream lighting fixtures with advantages such as energy saving and long service life. Figure 1 As shown, a conventional LED lamp 9 includes a lamp body 91, an optoelectronic assembly, and a live wire 92. The lamp body 91 has a cavity 911 for accommodating the optoelectronic assembly. The live wire 92 is mounted on the lamp body 91, with one end of the live wire 92 extending into the cavity 911 and electrically connected to the optoelectronic assembly to provide power to the assembly. To ensure that the live wire 92 meets pullout resistance requirements and prevents it from becoming detached from the optoelectronic assembly, it is typically treated with a retaining treatment.

[0003] like Figure 2 As shown, the first existing processing method is: first, a nut 93 is passed through the live wire 92 and the nut 93 is located outside the lamp body 91, and then a part of the live wire 92 is passed through the wire through hole 912 on the lamp body 91 into the accommodating cavity 911 of the lamp body 91, and then a wire fixing sleeve 94 with an external thread is sleeved on the part of the live wire 92 passed into the accommodating cavity 911, and a part of the wire fixing sleeve 94 is passed through the wire through hole 912 and threadedly connected to the nut 93, and then the live wire 92 is clamped and fixed on the lamp body 91 by the wire fixing sleeve 94 and the nut 93; wherein, in order to prevent the nut 93 from loosening, a spring washer 95 is also required to be provided between the lamp body 91 and the nut 93 to stop the nut 93.

[0004] like Figure 3As shown, the second existing processing method is: a stepped column portion 961 is provided on the wire-carrying wire 96; the stepped column portion 961 has a first step 9611, a second step 9612, a third step 9613 and a fourth step 9614 distributed in sequence from the outside of the lamp body 97 to the accommodating cavity 971, the height of the second step 9612 in the extension direction of the wire-carrying wire 96 is less than or equal to the height of the wire-passing channel (that is, the wall thickness of the lamp body 97), the third step 9613 and the fourth step 9614 are located in the accommodating cavity 971, and the diameter of the first step 9611 is greater than the diameter of the second step 9612, the diameter of the second step 9612 is less than or equal to the diameter of the wire-passing through hole 972, the diameter of the third step 9613 is less than the diameter of the second step 9612, and the diameter of the fourth step 9614 is greater than the diameter of the third step 9613 , so that the second step 9612 and the fourth step 9614 form a slot at the third step 9613; when the wired wire 96 is assembled with the lamp body 97, part of the stepped column 961 and part of the wired wire 96 pass through the wire-passing hole 972 on the lamp body 97 and enter the accommodating cavity 971 of the lamp body 97, wherein the first step 9611 is located outside the lamp body 97 and abuts against the outer peripheral wall of the lamp body 97, the second step 9612 is located in the wire-passing hole 972, and the third step 9613 and the fourth step 9614 are located in the accommodating cavity 971; then, an elastic clip 98 is engaged with the third step 9613 (i.e., in the slot) so that the elastic clip 98 cooperates with the first step 9611 to clamp the wired wire 96 on the lamp body 97, and the thickness of the elastic clip 98 needs to be greater than or equal to the height of the third step 9613.

[0005] However, both the first and second treatment methods have the disadvantage of requiring a large number of assembly parts, which makes assembly troublesome and increases costs; in addition, for the first treatment method, the wire sleeve 94 and the nut 93 are exposed outside the lamp body, which also affects the aesthetics of the LED lamp; and for the second treatment method, the assembly dimension requirements between the height of the second step 9612 of the stepped column 961 and the thick wall of the lamp body 97, and the assembly dimension requirements between the third step 9613 and the elastic clip 98 are relatively high, and due to the limited space of the accommodating cavity 971, the assembly of the elastic clip 98 and the slot is difficult. Summary of the Invention

[0006] In order to solve the above problems, the main purpose of the present invention is to provide an LED lamp that can ensure that the power supply wire meets the pull-out resistance requirements and makes the assembly of the power supply wire simpler.

[0010] A further solution is that the wire through hole also has an auxiliary limiting hole portion, which is connected between the through hole portion and the countersunk slot portion; the wire also has an auxiliary limiting card block, which is integrally formed on the outer periphery of the wiring harness body, and the contour of the auxiliary limiting card block is similar to the contour of the auxiliary limiting hole portion, and the auxiliary limiting card block is engaged in the auxiliary limiting hole portion; the first cross-section of the auxiliary limiting hole portion and the second cross-section of the auxiliary limiting card block are both non-circular.

[0011] As can be seen from the above, adding an auxiliary limiting hole portion to the wire through hole and adding an auxiliary limiting block to the wired wire to engage with the auxiliary limiting hole portion can further prevent the wired wire from rotating relative to the wire through hole, improve the anti-twisting effect, and better prevent the wired wire from being disconnected from the optoelectronic component and / or damaged and broken due to excessive twisting.

[0012] A preferred solution is that along the extension direction of the wiring harness body, the projection of the auxiliary limit block is located within the projection of the mating block; the first cross section and the second cross section are both polygonal or elliptical; the third cross section of the countersunk slot portion and the fourth cross section of the mating block are both polygonal or arch-like.

[0016] Another preferred solution is that the substrate of the optoelectronic component has an arc-shaped avoidance groove in the wiring harness body, and the arc-shaped avoidance groove penetrates the substrate in the thickness direction of the substrate.

[0017] As can be seen from the above, the provision of an arc-shaped avoidance groove can increase the area of ​​the optoelectronic component covering the countersunk slot portion, thereby improving the reliability of limiting the wired wires; at the same time, the arc-shaped avoidance groove can better prevent the wires of the wire harness body from being cut by the edge of the substrate while avoiding the wire harness body.

[0018] A further solution is that a first connecting through hole is provided on the substrate, and the first connecting through hole passes through the substrate in the thickness direction; a substrate connecting hole matching the first connecting through hole is provided at the bottom of the accommodating cavity, and the substrate connecting hole has a first chip removal groove.

[0022] A further solution is that the LED lamp further includes a fixing frame and a lens, the fixing frame is provided with a second connecting through hole matching with the first connecting through hole, the fixing frame has a receiving position, and the lens is installed in the receiving position.

[0023] As can be seen from the above, by setting up a fixing frame, the assembly of the lens is made more convenient, and at the same time, the accumulated tolerance in the assembly process can be reduced or eliminated, ensuring the tightness of the connection between the components after the LED lamp is assembled; in addition, a second connecting through hole is set on the fixing frame to cooperate with the first connecting through hole, which can simplify the structure of the heat dissipation lamp body, simplify the assembly steps, reduce the difficulty of assembly and reduce the number of fasteners required for assembly.

[0024] A further solution is that the heat dissipation lamp body is made of aluminum alloy and further has heat dissipation fins.

[0025] As can be seen from the above, using aluminum alloy to support the heat dissipation lamp body can ensure the heat dissipation effect of the heat dissipation lamp body on the optoelectronic components, ensuring the service life and working stability of the optoelectronic components, and providing heat dissipation fins on the heat dissipation lamp body can improve the heat dissipation performance of the heat dissipation lamp body.

[0040] LED lamp embodiment

[0041] Reference Figure 4 and Figure 5 The LED lamp 100 includes a heat dissipation lamp body 1, a conducting wire 2, a photoelectric component 3, a fixing frame 4 and a lens 5. Figure 6The heat dissipation lamp body 1 has a accommodating cavity 11, and a wire through hole 12, a substrate 31 connection hole 13 and a ground wire 213 connection hole 14 are formed at the bottom of the accommodating cavity 11; wherein, the wire through hole 12 passes through the heat dissipation lamp body 1 in the depth direction of the accommodating cavity 11, and the substrate 31 connection hole 13 and the ground wire 213 connection hole 14 preferably pass through the heat dissipation lamp body 1 in the depth direction; the wire through hole 12 preferably has a through hole portion 121 and a countersunk groove portion 122, and the countersunk groove portion 122 is recessed at the bottom of the accommodating cavity 11 away from the open opening of the accommodating cavity 11, and the countersunk groove portion 122 is connected between the through hole portion 121 and the accommodating cavity 11.

[0042] Combine Figures 7 to 9 The live wire 2 preferably includes a wiring harness body 21 and a mating block 22. The mating block 22 is preferably integrally formed on the outer periphery of the wiring harness body 21, and the contour of the mating block 22 is similar to the contour of the countersunk groove portion 122. When the live wire 2 is assembled with the heat sink body 1, the wiring harness body 21 is passed from the accommodating cavity 11 through the wire through hole 12 and extends to the rear end of the heat sink body 1, and the mating block 22 is engaged with the countersunk groove portion 122.

[0043] The third cross-section of the countersunk slot portion 122 and the fourth cross-section of the matching block 22 are preferably polygonal or arch-shaped to ensure that the live wire 2 will not twist or over-twist relative to the heat dissipation lamp body 1, thereby ensuring the protection effect of the live wire 2; as in the present embodiment, the third cross-section of the countersunk slot portion 122 and the fourth cross-section of the matching block 22 are both arch-shaped.

[0044] Preferably, the wire through hole 12 also has an auxiliary limiting hole portion 123, and the auxiliary limiting hole portion 123 is connected between the through hole portion 121 and the countersunk slot portion 122; matching, the wire 2 also has an auxiliary limiting block 23, and the auxiliary limiting block 23 is preferably integrally formed on the outer periphery of the wiring harness body 21, wherein the outline of the auxiliary limiting block 23 is similar to the outline of the auxiliary limiting hole portion 123. When the wire 2 is assembled with the heat dissipation lamp body 1, the auxiliary limiting block 23 is engaged in the auxiliary limiting hole portion 123. By adding the auxiliary limiting hole portion 123 to the wire through hole 12 and adding the auxiliary limiting block 23 to the wire 2 to engage with the auxiliary limiting hole portion 123, the wire 2 can be further prevented from rotating relative to the wire through hole 12, thereby improving the anti-twisting effect, so as to better prevent the wire 2 from being disconnected from the optoelectronic component 3 and / or damaged and broken due to excessive twisting.

[0045] The first cross-section of the auxiliary limiting hole portion 123 and the second cross-section of the auxiliary limiting block 23 are preferably non-circular, such as being polygonal or elliptical. In this embodiment, the first cross-section of the auxiliary limiting hole portion 123 and the second cross-section of the auxiliary limiting block 23 are both elliptical. Preferably, along the extension direction of the wiring harness body 21, the projection of the auxiliary limiting block 23 is located within the projection of the mating block 22. By designing the relative positions of the auxiliary limiting block 23 and the mating block 22, the structure of the wire 2 and the wire through hole 12 can be optimized, and the reliability of the engagement connection between the mating block 22 and the countersunk groove portion 122 can be ensured, thereby avoiding the failure of the mating block 22 due to the projection of the mating block 22 being located within the projection of the auxiliary limiting block 23.

[0046] It should be noted that, as a first optional solution, such as in the present embodiment, a slight gap may be provided between the countersunk groove portion 122 and the mating block 22, and a slight gap may be provided between the auxiliary limiting hole portion 123 and the auxiliary limiting block 23, so as to make the assembly between the heat dissipation lamp body 1 and the live wire 2 easier to operate. Of course, as a second optional solution, an interference fit is adopted between the countersunk groove portion 122 and the mating block 22, and an interference fit is adopted between the auxiliary limiting hole portion 123 and the auxiliary limiting block 23. This design can improve the tightness of the connection between the live wire 2 and the heat dissipation lamp body 1, enhance the pull-out resistance of the live wire 2, and better prevent the live wire 2 from rotating relative to the heat dissipation lamp body 1. In addition, the first height of the countersunk groove portion 122 can be greater than or equal to the second height of the matching block 22; preferably, the first height of the countersunk groove portion 122 is equal to the second height of the matching block 22, so that when the optoelectronic component 3 is installed in the accommodating cavity 11, the optoelectronic component 3 can be pressed against the matching block 22 to better limit the matching block 22, thereby better preventing the live wire 2 from moving in the axial direction of the wire through hole 12, improving the push-pull resistance of the live wire 2, and making the assembly between the heat dissipation lamp body 1, the optoelectronic component 3 and the live wire 2 more compact.

[0047] Combine Figure 10 The optoelectronic component 3 is installed in the accommodating cavity 11 and electrically connected to the live wire 2, and the optoelectronic component 3 partially covers the countersunk groove portion 122. Preferably, in this embodiment, the substrate 31 of the optoelectronic component 3 has an arc-shaped avoidance groove 311. The arc-shaped avoidance groove 311 penetrates the substrate 31 in the thickness direction of the substrate 31. The provision of the arc-shaped avoidance groove 311 can increase the area of ​​the optoelectronic component 3 covering the countersunk groove portion 122, thereby improving the reliability of limiting the live wire 2. At the same time, the arc-shaped avoidance groove 311 is used to avoid the wiring harness body 21 and can, to a certain extent, prevent the wires of the wiring harness body 21 from being cut by the edge of the substrate 31.

[0048] In addition, the substrate 31 is provided with a first connecting through hole 312, which penetrates the substrate 31 in the thickness direction; matchingly, the bottom of the accommodating cavity 11 is provided with a substrate 31 connecting hole 13 that cooperates with the first connecting through hole 312, and the substrate 31 connecting hole 13 has a first chip groove 131. The setting of the first chip groove 131 enables when the first bolt is used to connect the optoelectronic component 3 and the heat dissipation lamp body 1, during the process of the first bolt being connected to the substrate 31 connecting hole 13, the chips cut by the first bolt on the heat dissipation lamp body 1 can be discharged through the first chip groove 131, so as to ensure the tightness and reliability of the connection between the bolt and the heat dissipation lamp body 1; furthermore, by designing the connection structure between the substrate 31 and the heat dissipation lamp body 1, the optoelectronic component 3 can be better fitted to the bottom of the accommodating cavity 11, so as to ensure the heat dissipation effect of the heat dissipation lamp body 1 on the optoelectronic component 3. Preferably, the heat dissipation lamp body 1 is made of aluminum alloy to ensure that the heat dissipation lamp body 1 can reliably dissipate heat for the optoelectronic component 3, thereby ensuring the service life and working stability of the optoelectronic component 3; and, the heat dissipation lamp body 1 is preferably also provided with heat dissipation fins 15 to improve the heat dissipation performance of the heat dissipation lamp body 1.

[0049] A neutral wire 211 contact 313 and a live wire 212 contact 314 are also provided on the substrate 31; the wiring harness body 21 of the power-carrying wire 2 has a neutral wire 211, a live wire 212 and a ground wire 213, wherein the neutral wire 211 and the neutral wire 211 contact 313 are welded and fixed, and the live wire 212 and the live wire 212 contact 314 are welded and fixed, so that the power-carrying wire 2 can provide stable and reliable power supply to the optoelectronic component 3. Preferably, a wire lug 2131 is provided at the end of the ground wire 213. To match, a ground wire 213 connection hole 14 is also provided at the bottom of the accommodating cavity 11 of the heat sink lamp body 1. The ground wire 213 connection hole 14 is configured to cooperate with the wire lug 2131. When grounding the ground wire 213 to the heat sink lamp body 1, a second bolt is inserted through the through-hole in the wire lug 2131 and then connected to the ground wire 213 connection hole 14. The wire lug 2131 provided at the end of the ground wire 213 allows the ground wire 213 to be securely connected to the heat sink lamp body 1 via the second bolt, ensuring a secure grounding connection. Preferably, the ground wire 213 connection hole 14 has a second chip removal groove 141. This second chip removal groove 141 allows chips cut from the heat sink lamp body 1 by the second bolt during connection to the ground wire 213 connection hole 14 to be discharged through the second chip removal groove 141, thereby ensuring a secure and reliable connection between the second bolt and the heat sink lamp body 1.

[0050] Combine Figure 11A second connecting through hole 41 is provided on the fixing frame 4, and the second connecting through hole 41 is used to cooperate with the first connecting through hole 312 on the substrate 31 of the optoelectronic component 3, so that when the fixing frame 4 is installed, the first bolt can first pass through the second connecting through hole 41, then through the first connecting through hole 312, and finally connect with the connecting hole 13 of the substrate 31; it can be seen that this design can simplify the structure of the heat dissipation lamp body 1 and the substrate 31 (reducing the number of connecting holes on the heat dissipation lamp body 1 and the number of through holes on the substrate 31), simplify the assembly steps, reduce the difficulty of assembly and reduce the number of fasteners (such as bolts) required for assembly. In addition, the fixing frame 4 has a receiving position 42, and the lens 5 can be detachably installed in the receiving position 42; this design enables the lens 5 to be installed in the receiving cavity 11 through the fixing frame 4, thereby making the assembly of the lens 5 more convenient, and compared with the existing processing method of providing a positioning column on the lens 5 and a positioning hole on the substrate 31, it can better simplify the structure of the lens 5 and the substrate 31, and increase the strength of the substrate 31. At the same time, since the lens 5 does not need to rely on the substrate 31, anti-glare ring and other components for clamping and fixing, it can effectively reduce or eliminate the accumulated tolerance in the assembly process, thereby ensuring the tightness of the connection between the components after the LED lamp 100 is assembled.

[0051] In summary, it can be seen that through the above-mentioned design of the heat dissipation lamp body 1, the live wire 2, and the optoelectronic component 3, the live wire 2 can be limited by the engagement connection between the matching block 22 on the live wire 2 and the countersunk groove portion 122 on the heat dissipation lamp body 1, thereby preventing the live wire 2 from being pulled out of the heat dissipation lamp body 1 and preventing the live wire 2 from being disconnected from the optoelectronic component 3. In addition, the matching optoelectronic component 3 covers the countersunk groove portion 122, which can further limit the live wire 2 and prevent the live wire 2 from being pushed too far into the accommodating cavity 11. Furthermore, The engaging connection between the cooperating block 22 and the countersunk slot portion 122 can also prevent the live wire 2 from rotating relative to the wire through hole 12, thereby preventing the live wire 2 from being disconnected from the optoelectronic component 3 and / or damaged and broken due to excessive twisting; and compared with the existing LED lamp 100, the LED lamp 100 is more beautiful as a whole, and the assembly between the live wire 2 and the heat dissipation lamp body 1 will not occupy too much space in the accommodating cavity 11, and at the same time, the optoelectronic component 3 can be better fitted to the bottom of the accommodating cavity 11, so as to enhance the heat dissipation effect of the heat dissipation lamp body 1 on the optoelectronic component 3.
