A peripheral edge of the stopper 13 is fixed to the inner side of the front frame 11 by a third fastening member 100.

In an embodiment, referring to fig. 9 and 10, a plurality of elastic arms 131 are distributed on the limiting frame 13, each elastic arm 131 is distributed at equal intervals along the rotation direction of the lamp holder 12, a hanging end of each elastic arm 131 is provided with a limiting protrusion 132, and each limiting protrusion 132 is uniformly distributed along the rotation direction of the lamp holder 12. The end face of one end of the lamp holder base 12 is circumferentially and uniformly distributed with a plurality of limiting grooves 121, the number of the limiting grooves 121 is at least twice that of the limiting protrusions 132, and each limiting protrusion 132 can be in concave-convex fit with different limiting grooves 121 to limit the lamp holder base 12. Through the setting of a plurality of spacing archs 132 and a plurality of spacing recess 121, it not only plays the limited action to lamp holder seat 12, simultaneously because the quantity of spacing recess 121 is the multiple of spacing archs 132 quantity for each spacing arch 132 can cooperate with the spacing recess 121 of difference, thereby plays the effect of rotatory scale. Finally, due to the arrangement of the elastic arms 131, the elastic arms 131 have elasticity, so that a certain damping effect is achieved between the limiting grooves 121 and the limiting protrusions 132, when the rotating force is small, the lamp holder 12 cannot be rotated randomly, and the working stability of the whole lamp is improved.

Referring to fig. 9 and 10, the limiting frame 13 is provided with four elastic arms 131 and four limiting protrusions 132, and the lamp base 12 is provided with 36 limiting grooves 121, that is, the lamp base 12 is limited to be locked once every 10 degrees, so that the user can clearly see the rotating angle. It is understood that in other embodiments of the present application, the number of the limiting protrusions 132 and the number of the limiting grooves 121 may be adjusted according to actual requirements, and are not limited herein repeatedly.

Referring to fig. 4 and 5, the lamp head assembly 10 further includes a circuit board 15 and a connector 14, the circuit board 15 is disposed on a side of the first end cap 60 away from the light emitting assembly 20 and is accommodated in the front frame 11, the power board 32 and the light emitting board 21 are both in communication connection with the circuit board 15, the connector 14 is sleeved outside the lamp head base 12, the connector 14 is electrically connected to the circuit board 15, and the connector 14 is used for being inserted into an external socket to form communication connection with the external socket.

In an embodiment, referring to fig. 1, fig. 4 and fig. 6, a first mounting block 42 and a second mounting block 43 are disposed on an outer side of the connection shell 40 away from the lamp head assembly 10, and the first mounting block 42 and the second mounting block 43 are disposed at an interval along the second direction Y. The first mounting block 42 is provided with a first mounting hole 421 for mounting the external support frame 200, the second mounting block 43 is provided with a second mounting hole 431 for mounting the external support frame, and the first mounting hole 421 and the second mounting hole 431 both extend along the second direction Y. With the arrangement of the first mounting hole 421 and the second mounting hole 431, referring to fig. 1, when the lamp is mounted with the light-emitting plane 23 facing downward, the external support 200 can be mounted through the second mounting hole 431, specifically, one end of the external support 200 is fixed on the second mounting block 43 by a screw, and then the other end of the external support 200 is supported on the external support plane. When the lamp is installed in a manner that the light-emitting plane 23 is vertically disposed, one end of the external support frame 200 may be inserted between the first installation block 42 and the second installation block 43, and then one end of the external support frame 200 may be locked to the first installation hole 421 and the second installation hole 431 by screws, respectively. Through the arrangement of the first mounting block 42 and the second mounting block 43, when the lamp is not stably mounted, the lamp can be supported through the external support frame 200 to prevent the lamp from inclining.

Specifically, in the present embodiment, the second mounting block 43 is provided on the second end cap 70 at the lower end of the connection housing 40. It is understood that in other embodiments of the present application, the second mounting block 43 may be directly disposed outside the connecting shell 40, and is not limited thereto.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
