Embodiment
Referring to figs. 1 to Fig. 4, a kind of LED down lamp of adjustable-angle, including lamp body and connection ring 1, the connection ring 1 are pacified
Equipped with Lamp cup 2, the Lamp cup 2 is provided with loophole 3, and the lower end both sides of the lamp body are be hinged with the connection ring 1, the connection
Ring 1 is provided with the positioning hole 4 of arc, and the inwall of the positioning hole 4 is provided with some detents 5, the lamp body with it is described fixed
The relative position in position hole 4 is provided with the positioning bead 6 that can be embedded in the detent 5, is labeled with dimming angle at detent,
When adjusting light, positioning bead can be embedded in each detent, make to pause between lamp body and connection ring, convenient adjustment light
Angle, meet the light-illuminating requirement under varying environment.
The lamp body includes rear shell 8, and LED light source and lens 9, the lower end installation of the rear shell 8 are provided with the rear shell 8
There is pendular ring 10, the pendular ring 10 is provided with linking arm 11, and the linking arm 11 and connection ring 1 are provided with corresponding hinge axis hole
12, it is plugged with that hinge makes the linking arm 11 and connection ring 1 forms articulated structure in the hinge axis hole 12, on the linking arm 11
Be provided with the hole of bead 13 for installing the positioning bead 6, it is simple in construction, Lamp cup 2 and connection ring 1 can flexible rotating, convenient adjustment
Angle.
The mounting structure of the present embodiment is as follows:The madial wall of the rear shell 8 is provided with screens shell fragment 14, the screens shell fragment
14 are provided with screens portion 15, and the pendular ring 10 is provided with screens projection 16, and after assembling, it is convex that the screens portion 15 is connected to screens
Rise on 16;The side wall of the connection ring 1, which is provided with, fixes mouth 17, and the upper end of the Lamp cup 2 is provided with the embedded fixing mouth 17
Elastic card claw 18;The mounting ring 7 that can be circumferentially rotated is set with the connection ring 1, the lateral wall of the connection ring 1 is provided with
Circumferential screens scrobicular ring 19, the mounting ring 7 is provided with elastic fastening plate 20, and after assembling, the elastic fastening plate 20 is stuck in the card
In the scrobicular ring 19 of position, mounting ring 7, Lamp cup 2 can be freely simple from closing and dismounting, simple in construction, convenient disassembly, convenient maintenance and more
Change.
The loophole 3 is provided with the reflecting wall 21 to extend internally, and the radial cross-sectional area in the reflecting wall 21 is big
In projected area of the LED light source in the reflecting wall 21, in the present embodiment, the eccentric setting of loophole 3 and cut
Face is that both ends are the strips that arc, on both sides of the middle are straight line, and the trend of strip loophole is parallel with the swaying direction of Lamp cup,
