The lamp provided by the embodiment of the invention is explained.

In one embodiment of the present invention, referring to fig. 1 and 2, the lamp includes a lamp housing 1, a circuit board 2 and an antenna structure 3, wherein the lamp housing 1 may be a metal cover, a plastic cover, etc. The circuit board 2 is arranged in the lamp housing 1, and the lamp housing 1 protects the circuit board 2 and internal devices. The circuit board 2 is connected to an external power source through a cable, a connector, or the like. When the antenna structure 3 is located in the lamp, the lamp housing 1 easily shields electromagnetic waves received and emitted by the antenna, and particularly when the lamp housing 1 is a metal housing, the lamp housing 1 is equivalent to a shielding cover, and the receiving and transmitting signals of the antenna are shielded. Therefore, one end of the antenna structure 3 extends out of the lamp housing 1, so that the performance of the antenna can be improved, and the reliability of wireless signal receiving and transmitting is ensured. The lamp housing 1 is provided with a first antenna hole 10 for the antenna structure 3 to pass through, 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, and the other end of the antenna structure 3 passes through the first antenna hole 10 to the outside of the lamp.

The lamp in the above embodiment comprises the lamp housing 1, the circuit board 2 and the antenna structure 3, wherein the antenna structure 3 is in circuit connection with the circuit board 2 to realize wireless communication with the outside, and one end of the antenna structure 3 extends out of the lamp housing 1, so that the lamp housing 1 can not influence the antenna structure 3 to send and receive signals even when being a metal piece, and normal communication of the antenna structure 3 can be ensured.

In one embodiment of the present invention, referring to fig. 3 and 4, the antenna structure 3 includes an antenna body 31 and a protective sleeve 32. The antenna body 31 may be wire-shaped, 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 outside the antenna body 31 and is used for supporting and protecting the antenna body 31. Alternatively, one end of the protective sleeve 32 is located outside the lamp envelope 1 and one end is located inside the lamp envelope 1, or the protective sleeve 32 is located entirely outside the lamp envelope 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 includes a hard segment 322 and a soft segment 321, the hard segment 322 and the soft segment 321 are connected to each other, the hard segment 322 is located inside the lamp housing 1, at least a part of the soft segment 321 is located outside the lamp housing 1, and the soft segment 321 can be bent and deformed. When the lamp is applied to an outdoor scene, a shovel is used during construction, a lawnmower blows broken stones, and external forces such as fallen branches impact the antenna structure 3, the soft section 321 outside the lamp housing 1 can be bent and deformed, so that the protective sleeve 32 cannot be broken, and the function of protecting the antenna structure 3 is achieved. Hard segment 322 may be made of hard gelatin and soft segment 321 may be made of soft gelatin. Optionally, the protective sleeve 32 is conical, and 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 high and is not easy to break.

Alternatively, the hard segment 322 and the soft segment 321 are integrally assembled after being respectively processed and molded, and the hard segment 322 and the soft segment 321 are easier to be separately molded and manufactured due to different materials, or the hard segment 322 and the soft segment 321 can be molded into another segment after one segment is molded by injection, so that the hard segment 322 and the soft segment 321 do not need to be assembled.

When the hard segment 322 and the soft segment 321 are molded separately, the soft segment 321 is inserted into the hard segment 322. Since the soft segment 321 can be deformed, the soft segment 321 can be easily inserted into the hard segment 322. Referring to fig. 4 and 5, the outer wall of the soft segment 321 near one end of the hard segment 322 is provided with a first limiting protrusion 3211, the inner wall of the hard segment 322 is provided with a first limiting groove 3221, and the first limiting protrusion 3211 and the first limiting groove 3221 are mutually matched to limit the circumferential directions of the soft segment 321 and the hard segment 322, so as to prevent the hard segment 322 and the soft segment 321 from rotating relative to the circumferential directions. The number of the first stopper protrusions 3211 and the first stopper grooves 3221 is not limited herein. The first limiting protrusion 3211 and the first limiting groove 3221 may have square, triangular or semicircular cross-section, and other shapes. The surface protrusion of the first spacing protrusion 3211 is provided with a second spacing protrusion 3212, the side surface of the second spacing protrusion 3212 is provided with a first spacing step surface 32121 (in combination with fig. 5, the first spacing step surface 32121 is located at the bottom of the second spacing protrusion 3212), a second spacing groove 3222 is correspondingly formed in the first spacing groove 3221, the second spacing groove 3222 is provided with a second spacing step surface 32221, when the soft segment 321 is inserted into the hard segment 322, the first spacing protrusion 3211 is located in the first spacing groove 3221, the second spacing protrusion 3212 is located in the second spacing groove 3222, and the first spacing step surface 32121 and the second spacing step surface 32221 are mutually abutted, thereby defining the axial relative positions of the soft segment 321 and the hard segment 322. Because soft segment 321 and hard segment 322 are pegged graft the back, soft segment 321 and hard segment 322 extrudees each other, and frictional force between the two is great, therefore makes soft segment 321 and hard segment 322 be difficult for taking off.

In other embodiments, hard segment 322 may be inserted into soft segment 321, just as described for one implementation where hard segment 322 and soft segment 321 are connected.

When the external sleeve 33 is impacted by an external object, the external sleeve and the soft section 321 are bent and deformed together, so that the external sleeve is prevented from being broken. One end (root end) of the external sleeve 33 is fixed at the first antenna hole 10 of the lamp housing 1, and can axially limit the top of the soft segment 321, so as to prevent the soft segment 321 from axially falling off.
