Serve one of the face ring component 1 is to inject LED light source 32 in first accommodation space dissipate,
Expand the angle that light enters the first accommodation space.Therefore, the face ring component 1 has a lens 12, and the lens 12 are along axle
To the direction evagination away from LED light source 32；When the buckle 11 connects and fixes with bayonet socket 311, the lens 12 and LED bases
Plate 31, which surrounds, forms an emitting cavity；The light that LED light source 32 is sent enters after emitting cavity reflects outside injection through lens 12.
Serve one of the face ring component 1 is by after the light reflection in the first accommodation space, from the first opening
Projected at 21.Therefore, the face ring component 1 also includes an annulus 13, passes through one between the inner circumferential of annulus 13 and the periphery of lens 12
The reflective surface 14 that diameter gradually tapers up connects；The reflective surface 14 circumferentially has the reflecting unit 141 of rasterizing, described anti-
The concentric circles of the multiple stackings of the arrangement form of light unit 141, the center of circle of concentric circles are axially distributed, and with one heart diameter of a circle by
Taper contracting.Light in such first accommodation space is after the reflection of reflecting unit 141, it becomes possible to all at the first opening 21
Project, reduce the loss of light, add except brightness.
In order to which Down lamp is attached in mounting cylinder, the annulus 13 is provided with least two installations towards the side of radiating piece 2
Post 131, each mounting post 131 is corresponding to be fixedly connected with a torsion spring 132；The torque arm of the torsion spring 132 is in same level
It is distributed in face in rotational symmetry.When Down lamp and mounting cylinder are installed, it is only necessary to Down lamp is put into mounting cylinder, and rotary cylinder
Lamp so that the inwall of mounting cylinder occurs to extrude and then causes torque arm to produce elasticity to the inwall of mounting cylinder with the torque arm of torsion spring 132
Reset force.So that Down lamp is fixedly mounted with mounting cylinder.Mounting post 131 can also be three or more, and mounting post is more, cylinder
The mounting stability of lamp is also higher.Torsion spring 132 can also be installed using screw, i.e., in annulus 13 towards radiating piece 2 one
Side sets at least two screws, and each screw one torsion spring 132 of corresponding installation, this belongs to the extension and letter of the present embodiment structure
It is single to replace, repeat no more.
In addition, the periphery of the annulus 13 is arranged at intervals with multiple arc surfaces 133 to be concaved along footpath.Structure increase
Visual comfort is met while the smart of Down lamp outer tube, increase aesthetic property, helps people to adjust micro- mood.
The present embodiment, driving lid 42 and second are coordinated between openend 22 using grafting, are specially：The driving lid
42 one side towards the second openends 22 is circumferentially provided with multiple first joint bars 421, and first joint bar 421 is towards close
The direction extension of second openend 22.Second openend 22 is circumferentially provided with to coordinate with first joint bar 421 and inserted
The first slot 221 connect.By the cooperation grafting of the first joint bar 421 and the first slot 221, the driving lid 42 and second is open
End 22 just links together.
