In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0027] The lamp provided by the embodiment of the present application will be described.

[0028] In one embodiment of the present application, referring to Figure 1 and Figure 2 , the lamp comprises a lamp shell 1, a circuit board 2 and an antenna structure 3. The lamp shell 1 can be a metal shell, a plastic shell, etc. The circuit board 2 is arranged inside the lamp shell 1, and the lamp shell 1 protects the circuit board 2 and internal devices. The circuit board 2 is connected with an external power supply through a cable, a connector, etc. When the antenna structure 3 is entirely located inside the lamp, the lamp shell 1 is easy to shield the electromagnetic waves received and emitted by the antenna, especially when the lamp shell 1 is a metal shell, the lamp shell 1 is equivalent to a shielding cover, shielding the receiving and transmitting signals of the antenna. Therefore, the end of the antenna structure 3 is arranged to protrude out of the lamp shell 1, which can improve the performance of the antenna and ensure the reliability of wireless signal receiving and transmitting. A first antenna hole 10 is formed on the lamp shell 1, through which the antenna structure 3 passes. One end of the antenna structure 3 is electrically connected with the circuit board 2, so that the antenna structure 3 has a wireless communication function. The other end of the antenna structure 3 passes through the first antenna hole 10 to the outside of the lamp.

[0029] The lamp in the above embodiment comprises a lamp shell 1, a circuit board 2 and an antenna structure 3. The antenna structure 3 is electrically connected with the circuit board 2 to realize wireless communication with the outside world. One end of the antenna structure 3 is arranged to protrude out of the lamp shell 1, so that even if the lamp shell 1 is a metal part, it will not affect the receiving and transmitting signals of the antenna structure 3, and the normal communication of the antenna structure 3 can be ensured.

[0030] In one embodiment of the present application, referring to Figure 3 and Figure 4The antenna structure 3 comprises an antenna body 31 and a protective sleeve 32. The antenna body 31 can be in the shape of a wire, one end of the antenna body 31 is electrically connected to the circuit board 2, and the other end of the antenna body 31 extends out of the lamp housing 1 through the first antenna hole 10. The protective sleeve 32 is sleeved on the outside of the antenna body 31, and is used for supporting and protecting the antenna body 31. Optionally, one end of the protective sleeve 32 is located outside the lamp housing 1, and the other end is located inside the lamp housing 1; or the protective sleeve 32 is entirely located outside the lamp housing 1. When one end of the protective sleeve 32 is located outside the lamp housing 1 and the other end is located inside the lamp housing 1, the protective sleeve 32 comprises a hard section 322 and a soft section 321, the hard section 322 and the soft section 321 are connected to each other, the hard section 322 is located inside the lamp housing 1, and at least part of the soft section 321 is located outside the lamp housing 1. The soft section 321 can be bent and deformed. When the lamp is applied to an outdoor scene, the antenna structure 3 is impacted by external forces such as shovels during construction, flying stones of lawn mowers, and falling branches, and the soft section 321 outside the lamp housing 1 can be bent and deformed, so that the protective sleeve 32 is not broken, thereby protecting the antenna structure 3. The hard section 322 can be made of hard glue, and the soft section 321 can be made of soft glue. Optionally, the protective sleeve 32 is in the shape of a cone, and gradually tapers from the inside of the lamp housing 1 to the outside of the lamp housing 1, so that the structural strength of the root of the protective sleeve 32 is relatively large, and the protective sleeve 32 is not easy to be damaged.

[0031] Optionally, the hard section 322 and the soft section 321 are separately processed and formed, and then are installed as a whole. The hard section 322 and the soft section 321 are more easily separated and formed due to the difference in material. Alternatively, the hard section 322 and the soft section 321 can be first injection molded into one section, and then injection molded into the other section, so that the hard section 322 and the soft section 321 do not need to be installed.

[0032] When the hard section 322 and the soft section 321 are separately formed, the soft section 321 is inserted into the hard section 322. Since the soft section 321 can be deformed, the soft section 321 can be easily inserted into the hard section 322. Please refer to Figure 4 and Figure 5The soft segment 321 has a first limiting protrusion 3211 on its outer wall near the hard segment 322, and a first limiting groove 3221 is formed on the inner wall of the hard segment 322. The first limiting protrusion 3211 and the first limiting groove 3221 cooperate with each other to limit the circumferential movement of the soft segment 321 and the hard segment 322, preventing relative circumferential rotation between them. The number of first limiting protrusions 3211 and first limiting grooves 3221 is not limited here. The first limiting protrusions 3211 and first limiting grooves 3221 can be in the shape of a block, a square, a triangle, or a semi-circular strip. A second limiting protrusion 3212 is provided on the surface of the first limiting protrusion 3211, and the side of the second limiting protrusion 3212 has a first limiting step surface 32121 (in conjunction with...). Figure 5 The first limiting step surface 32121 is located at the bottom of the second limiting protrusion 3212. A second limiting groove 3222 is correspondingly formed inside the first limiting groove 3221. The second limiting groove 3222 has a second limiting step surface 32221. When the soft segment 321 is inserted into the hard segment 322, the first limiting protrusion 3211 is located in the first limiting groove 3221, and the second limiting protrusion 3212 is located in the second limiting groove 3222. The first limiting step surface 32121 and the second limiting step surface 32221 abut against each other, thereby limiting the axial relative position of the soft segment 321 and the hard segment 322. Because the soft segment 321 and the hard segment 322 are pressed against each other after insertion, the friction between them is large, making it difficult for the soft segment 321 and the hard segment 322 to loosen.

[0033] In other embodiments, the hard segment 322 may also be inserted into the soft segment 321. The above is only one embodiment of the connection between the hard segment 322 and the soft segment 321.

[0034] In one embodiment of the present invention, please refer to Figures 1 to 3 The lamp also includes an outer sleeve 33, which can also be made of soft rubber and can be bent and deformed. The outer sleeve 33 is fitted around the outer periphery of the soft section 321, that is, it is set on the outside of the lamp housing 1. When impacted by an external object, the outer sleeve 33 and the soft section 321 bend and deform together to prevent breakage. One end (the root end) of the outer sleeve 33 is fixed at the first antenna hole 10 of the lamp housing 1, which can axially limit the top of the soft section 321 and prevent the soft section 321 from axially falling off.

[0035] Optionally, please refer to Figure 3The outer periphery of the outer sleeve 33 is provided with an annular groove 331, the longitudinal section of the annular groove 331 is U-shaped, one end of the outer sleeve 33 is inserted into the first antenna hole 10, and the hole wall of the first antenna hole 10 is inserted into the annular groove 331. Since the outer sleeve 33 can be bent and deformed, and is made of soft material, the outer sleeve 33 can be tightly fitted with the first antenna hole 10. In this way, when the outer sleeve 33 is fixed on the lamp housing 1, the first antenna hole 10 is simultaneously sealed, which is suitable for outdoor use of the lamp.

[0036] In one embodiment of the present application, referring to Figure 2 and Figure 3 , the lamp further comprises a base 4 for fixing the protective sleeve 32, the base 4 is arranged inside the lamp housing 1 and can be directly fixed on the inner wall of the lamp housing 1 or fixed inside the lamp housing 1 through a module support 6. Since the soft section 321 of the protective sleeve 32 at least partially extends out of the lamp housing 1, the hard section 322 of the protective sleeve 32 is arranged close to the base 4 and fixed on the base 4.

[0037] Specifically, the base 4 is provided with a second antenna hole 41 for the antenna body 31 to pass through, and the protective sleeve 32 and the circuit board 2 are arranged on opposite sides of the base 4, so the antenna body 31 needs to pass through the second antenna hole 41 of the base 4 to be electrically connected with the circuit board 2. One end of the hard section 322 away from the soft section 321 is fixed at the second antenna hole 41. The end of the hard section 322 away from the soft section 321 passes through the second antenna hole 41, and the end of the hard section 322 has an annular boss 3233 which is protruded radially outward from the outer periphery of the hard section 322, and the annular boss 3233 is used to abut against the base 4. A sealing gasket 34 is arranged between the annular boss 3233 and the base 4, and when the hard section 322 is fixed on the base 4, the annular boss 3233 and the base 4 are pressed tightly, so as to seal the second antenna hole 41 and prevent water vapor from entering the circuit board 2. The end of the hard section 322 away from the soft section 321 can be continuously stepped, and the base 4 is also continuously stepped correspondingly to cooperate with the hard section 322, so as to further increase the sealing performance of the second antenna hole 41.

[0038] Optionally, referring to Figure 4 , one end of the hard section 322 is radially extended to form a fixing lug 3224, the fixing lug 3224 is fixedly connected with the base 4 through a fastener such as a screw, so as to press the sealing gasket 34 and seal the second antenna hole 41. The number of the fixing lug 3224 can be two, which are symmetrically arranged relative to the axis of the protective sleeve 32.

[0039] In one embodiment of the present application, referring to Figure 1 and Figure 2The lamp further comprises a module support 6 and a light source assembly 7, both of which are arranged inside the lamp shell 1. The light source assembly 7 is fixed to the module support 6. The module support 6 can be directly fixed to the inner wall of the lamp shell 1. The module support 6 is a support for the internal structure of the lamp. The module support 6 and the structural member fixed to the module support 6 can form a light emitting module as a whole and can be independently assembled, which facilitates replacement and disassembly. The base 4 is fixed to the module support 6 or is integrally formed with the module support 6. When the base 4 is fixed to the module support 6, the base 4 can be snap-connected or fixed to the module support 6 by screws. The side of the base 4 facing the module support 6 can be provided with a positioning groove 61. The module support 6 is provided with a positioning rib 42. When the base 4 and the module support 6 are assembled, the positioning rib 42 is inserted into the positioning groove 61, which can well position the base 4. Then, the base 4 is fixed to the module support 6 by snap connection or screws.

[0040] Optionally, the module support 6 can be in a cylindrical shape and has a partition plate inside. The base 4 and the circuit board 2 are arranged on one side of the partition plate, and the light source assembly 7 is arranged on the other side of the partition plate. The light source assembly 7 is electrically connected to the circuit board 2. That is, the base 4, the circuit board 2 and the light source assembly 7 can be arranged in sequence along the light emitting direction. The light source assembly 7 can include a light source plate and a lens.

[0041] In one of the embodiments of the present application, referring to Figure 2 The interior of the lamp shell 1 is provided with a first magnetic member 51, and the module support 6 or the base 4 is fixed with a second magnetic member 52. The first magnetic member 51 and the second magnetic member 52 attract each other, which can quickly position the light emitting module and the lamp shell 1 when the light emitting module is installed, which can accelerate the installation speed and ensure the consistency of the installation position. When the lamp shell 1 is a metal shell, a plastic adapter 53 is fixed inside the lamp shell 1. The plastic adapter 53 can be fixed inside the lamp shell 1 by means of glue dispensing or threaded connection. The first magnetic member 51 is fixed to the plastic adapter 53. The metal lamp shell 1 has a large processing difficulty and high cost. By arranging the plastic adapter 53, the structural complexity of the metal lamp shell 1 can be reduced, and the processing cost can be reduced. When the second magnetic member 52 is fixed to the base 4, the base 4 can be provided with a receiving groove. The second magnetic member 52 is arranged in the receiving groove and can be fixed in the receiving groove by a sticking member.

[0042] Optionally, the lamp shell 1 and the light emitting module are both in a cylindrical shape, and after the light emitting module is installed, the light emitting module is easy to shake in the inside of the lamp shell 1. The outer periphery of the module support 6 is sleeved with a buffer ring, the buffer ring is clamped between the outer periphery of the module support 6 and the inner wall of the lamp shell 1, and can play a role of preventing the light emitting module from shaking. The outer periphery of the module support 6 is provided with at least one annular accommodating groove 62 for accommodating the buffer ring. The buffer ring can be made of a material that can be moderately deformed, such as a rubber ring or a silica gel ring. When the light emitting module is installed, the buffer ring can be moderately extruded, the light emitting module can be installed without impact, the light emitting module and the lamp shell 1 can be quickly aligned through the first magnetic attraction member 51 and the second magnetic attraction member 52, and the installation is facilitated.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
