[0006] In some embodiments, the outer surface of the sealing ring is provided with at least one rib, and each rib abuts against the second sidewall.

[0007] In some embodiments, the second sidewall is provided with a second inclined step, the second inclined step extends obliquely toward the first sidewall, the first inclined step and the second inclined step are opposite to each other, and the sealing ring abuts against the second inclined step.

[0008] In some embodiments, the sealing ring has an arcuate portion that abuts against the first inclined step.

[0009] In some embodiments, a sealing groove is provided on the cover, and the cover is also provided with a hollow groove that communicates with the sealing groove and is located on the side of the sealing groove away from the housing.

[0010] In some embodiments, the cover is provided with a plurality of reinforcing ribs, which are disposed in the hollow groove, and the sealing ring abuts against each of the reinforcing ribs.

[0011] In some embodiments, at least one boss is provided at one end of the housing facing the cover, and each boss abuts against the end of the sealing ring away from the slot.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1 , Figure 2 and Figure 3The lighting device 100 includes a housing 1, a cover 2, a light-emitting module 3, and a sealing ring 4. The housing 1 has a receiving groove 11, and the light-emitting module 3 is disposed within the receiving groove 11. The cover 2 is fixed to the housing 1 and covers the opening of the receiving groove 11 to protect the light-emitting module 3 within the receiving groove 11. Please refer to [reference needed]. Figure 3 and Figure 4 One of the housing 1 and the cover 2 is provided with a sealing groove 21, which is generally annular. The sealing groove 21 has a first sidewall 22 and a second sidewall 23 disposed opposite to each other. The first sidewall 22 is provided with a first inclined step 221, which extends obliquely toward the second sidewall 23. At least a portion of the sealing ring 4 is received in the sealing groove 21, and one end of the sealing ring 4 abuts against the first inclined step 221. The other of the housing 1 and the cover 2 abuts against the end of the sealing ring 4 away from the first inclined step 221. In this embodiment, by providing the sealing ring 4 between the cover 2 and the housing 1, the sealing ring 4 is used to improve the sealing performance between the cover 2 and the housing 1, reducing the risk of external water entering the receiving groove 11 from the gap between the cover 2 and the housing 1. By providing a first inclined step 221 on the first sidewall 22, when the cover 2 is fixed to the housing 1, the sealing ring 4 can remain in contact with the first inclined step 221 under the squeezing action of the cover 2 and the housing 1. This helps to improve the sealing performance between the cover 2 and the housing 1, thereby reducing the risk of water entering the receiving tank 11 when the lighting device 100 is working outdoors, and thus reducing the risk of the light-emitting module 3 in the receiving tank 11 being damaged by moisture.

[0022] In some embodiments, please refer to Figure 3 and Figure 4 The sealing ring 4 is roughly annular, and has an inner side 41 facing the center and an outer side 42 facing the outside. The inner side 41 of the sealing ring 4 abuts against the first side wall 22, and the outer side 42 of the sealing ring 4 abuts against the second side wall 23. The sealing ring 4 and the sealing groove 21 form an interference fit, thereby improving the sealing performance between the sealing ring 4 and the sealing groove 21.

[0023] Specifically, the distance between the first sidewall 22 and the second sidewall 23 is less than the width of the sealing ring 4. When the sealing ring 4 is placed in the sealing groove 21, the sealing ring 4 undergoes elastic deformation, thereby forming an interference fit between the sealing ring 4 and the sealing groove 21. This allows the inner surface 41 of the sealing ring 4 to abut against the first sidewall 22, and the outer surface 42 of the sealing ring 4 to abut against the second sidewall 23, thereby improving the sealing performance between the sealing ring 4 and the sealing groove 21.

[0024] In some embodiments, please refer to Figure 3 and Figure 4The aforementioned sealing groove 21 is provided on the cover 2. The sealing groove 21 extends approximately along the edge of the cover 2. When the cover 2 covers the opening of the receiving groove 11 and is fixed to the housing 1, the housing 1 abuts against the end of the sealing ring 4 away from the first inclined step 221. Under the combined action of the housing 1 and the first inclined step 221, the housing 1 applies a force along the first direction X to the sealing ring 4. This force causes the sealing ring 4 to undergo elastic deformation in the first direction X, thereby keeping the sealing ring 4 abutting against the first inclined step 221, which is beneficial to improving the sealing performance between the sealing ring 4 and the sealing groove 21. The first direction X is parallel to the arrangement direction of the housing 1 and the cover 2. It is worth noting that, due to the interference fit between the sealing ring 4 and the sealing groove 21, a seal is formed between the sealing ring 4 and the first side wall 22 and the second side wall 23 of the sealing groove 21. At the same time, due to the compression of the sealing ring 4 by the housing 1, the sealing ring 4 is kept in contact with the first inclined step 221, thereby forming a seal between the sealing ring 4 and the first inclined step 221. That is to say, in this embodiment, seals are formed between the sealing ring 4 and the first side wall 22, between the sealing ring 4 and the first inclined step 221, and between the sealing ring 4 and the second side wall 23, so that at least three sealing structures are formed between the sealing ring 4 and the sealing groove 21, which is beneficial to improving the sealing performance of the sealing ring 4 between the sealing groove 21.

[0025] It is understood that the sealing groove 21 can be set on the cover 2 or the housing 1. Both methods can achieve the sealing between the cover 2 and the housing 1. This application will not describe in detail the scheme of setting the sealing groove 21 on the housing 1.

[0026] It should be noted that, due to the interference fit between the sealing ring 4 and the sealing groove 21, if the entire outer surface 42 of the sealing ring 4 is abutted against the second sidewall 23, it will increase the difficulty of installing the sealing ring 4 into the sealing groove 21. To at least partially solve the above problem, in some embodiments, please refer to... Figure 3 The outer surface 42 of the sealing ring 4 is provided with at least one raised rib 421, and the raised ribs 421 are distributed at intervals along the first direction X, and each raised rib 421 abuts against the second sidewall 23. In this embodiment, by providing raised ribs 421 and abutting against the second sidewall 23, the difficulty of installing the sealing ring 4 into the sealing groove 21 can be reduced while achieving a seal between the sealing ring 4 and the second sidewall 23.

[0027] In some embodiments, please refer to 3 and Figure 4The second sidewall 23 is provided with a second inclined step 231, which is opposite to the first inclined step 221. The second inclined step 231 extends inclinedly toward the first sidewall 22. The sealing ring 4 abuts against the second inclined step 231. In this embodiment, by providing the second inclined step 231, the sealing ring 4 abuts against the second inclined step 231, which is beneficial to further improve the sealing performance between the sealing ring 4 and the sealing groove 21, thereby improving the sealing performance between the shell 1 and the cover 2.

[0028] In some embodiments, the end of the sealing ring 4 away from the cover 2 is provided with an arc-shaped portion 43, which abuts against the first inclined step 221. In this embodiment, by making the end of the sealing ring 4 away from the cover 2 arc-shaped, that is, by having the arc-shaped portion 43 abut against the first inclined step 221, it is beneficial to improve the sealing performance between the sealing ring 4 and the first inclined step 221, thereby improving the sealing performance between the cover 2 and the shell 1.

[0029] In some embodiments, the sealing ring 4 is provided with two arc-shaped portions 43 at one end away from the housing 1, one arc-shaped portion 43 abutting against the first inclined step 221 and the other arc-shaped portion 43 abutting against the second inclined step 231, thereby further improving the sealing performance between the cover 2 and the housing 1, thereby reducing the risk of water entering the receiving tank 11 when the lighting device 100 is working outdoors, thereby reducing the risk of the light-emitting module 3 in the receiving tank 11 being damaged by moisture.

[0030] In some embodiments, please refer to Figure 3 and Figure 6 The cover 2 is provided with a slot 24, which communicates with the sealing groove 21. The slot 24 is located at the end of the sealing groove 21 away from the housing 1. In this embodiment, by providing the slot 24, the material of the cover 2 can be reduced, thereby reducing the cost and the weight of the cover 2.

[0031] In some embodiments, the cover 2 is provided with a plurality of reinforcing ribs 25, which are spaced apart along the extending direction of the slot 24. The reinforcing ribs 25 are housed within the slot 24 and connected to the sidewall of the slot 24. The end of the sealing ring 4 away from the housing 1 abuts against each reinforcing rib 25. In this embodiment, by providing a plurality of reinforcing ribs 25, the strength of the cover 2 can be increased, reducing the risk of deformation of the cover 2 under the pressure of the sealing ring 4 and the housing 1.

[0032] In some embodiments, along the first direction X, the height of each reinforcing rib 25 near the end of the sealing ring 4 is equal, so that the sealing ring 4 can simultaneously abut against each reinforcing rib 25, which is beneficial to improving the sealing performance between the sealing ring 4 and the cover 2.

[0033] In some embodiments, please refer to Figure 3 and Figure 4 At least one boss 12 is provided at the end of the housing 1 facing the cover 2. When viewed along the first direction X, each boss 12 surrounds the receiving groove 11 and abuts against the end of the sealing ring 4 away from the empty groove 24. In this embodiment, by providing the boss 12 and abutting against the sealing ring 4, the sealing performance between the housing 1 and the sealing ring 4 is improved, thereby improving the sealing performance between the cover 2 and the housing 1.

[0034] In some embodiments, the lighting device 100 further includes a light-transmitting cover 5. The housing 1 is provided with a light-emitting hole 13, which communicates with the receiving groove 11. The light-transmitting cover 5 is disposed on the surface of the housing 1 away from the cover 2 and covers the light-emitting hole 13. The light-emitting module 3 is housed in the receiving groove 11 and is at least partially exposed to the light-emitting hole 13 so that the light emitted by the light-emitting module 3 can be emitted to the outside through the light-emitting hole 13 and the light-transmitting cover 5.

[0035] In this embodiment, by placing a sealing ring 4 between the cover 2 and the housing 1, the sealing ring 4 improves the sealing performance between the cover 2 and the housing 1, reducing the risk of external water entering the receiving groove 11 through the gap between the cover 2 and the housing 1. By providing a first inclined step 221 on the first sidewall 22, when the cover 2 and the housing 1 are fixed together, the sealing ring 4 can remain in contact with the first inclined step 221 under the squeezing action of the cover 2 and the housing 1, which helps to improve the sealing performance between the cover 2 and the housing 1. This reduces the risk of water entering the receiving groove 11 when the lighting device 100 is working outdoors, thereby reducing the risk of the light-emitting module 3 in the receiving groove 11 being damaged by moisture.

[0036] This application also provides an embodiment of a lighting system, which includes the lighting device 100 described above. For the specific structure and function of the lighting device 100, please refer to the above embodiments, which will not be repeated here.
