By sleeving the elastic gasket 630 on the fastener 620, when the fastener 620 fixes the wire pressing member 610, on one hand, the elastic gasket 630 can prevent the fastener 620 from scratching the wire pressing member 610, disperse the pressing force of the fastener 620 on the wire pressing member 610, and simultaneously provide elastic support for the fastener 620 so as to prevent the fastener 620 from loosening, so that the use effect is good.

Referring to fig. 1 and 6, in some embodiments, the lighting device 10 further includes a protective component 900, and the protective component 900 covers the light passing hole 111. From this setting, protection component 900 can protect logical unthreaded hole 111, can avoid in the lighting device 10 use debris striking lighting component 200 and/or lamp shade subassembly 800 to cause the damage to it, and then guarantee lighting device 10's protecting effect.

Specifically, referring to fig. 6, the protection assembly 900 includes a protection screen 910 and a screen fixing member 920, the protection screen 910 is covered on the light through hole 111, and the screen fixing member 920 is detachably connected to the housing 100 and is used for fixing the protection screen 910 on the housing 100.

When the lighting device 10 of the present embodiment is assembled, the protective mesh 910 is firstly covered on the light-transmitting hole 111, and the protective mesh 910 surrounds the light-transmitting hole 111 to protect the light-transmitting hole 111, so that the light emitted by the lighting device 200 can be transmitted through the protective mesh 910, and then the mesh fixing member 920 abuts against the protective mesh 910 and is fixed on the housing 100 to complete the installation of the protective device 900; mesh enclosure mounting 920 may be removably attached to housing 100, for example, by screws, snaps, adhesives, or inserts, to facilitate the assembly and disassembly of shield assembly 900.

Referring to fig. 6, the casing 100 further includes a connection chain 140, and the connection chain 140 is connected to the front casing 110 and the rear casing 120 in sections; when the lighting device 10 is disassembled and maintained, the front housing 110 and the rear housing 120 can be connected by the connecting chain 140, so that the front housing 110 and/or the rear housing 120 are prevented from being lost.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
