Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202322980266.4, filed on Nov. 3, 2023, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the field of lighting fixtures, and in particular to an elastic assembly and a down lamp.

BACKGROUND

With regard to a traditional American-standard down lamp, it is necessary to connect a spring on the down lamp with a Halo barrel (i.e., a fixed barrel) during assembly, while two springs on such down lamps need to be pressed into the Halo barrel at the same time to complete the assembly, and the springs on two sides in the radial direction of the down lamp are both arranged towards the axial direction of the down lamp and the angle of the springs is fixed. The assembly process requires the installer to operate with both hands, which is cumbersome. If the connection of two springs is completed by means of single-side assembly, the springs are easy to pop out from the Halo barrel during the installation process due to the unbalanced stress on the two sides of the down lamp, which may easily lead to deformation or fracture of the Halo barrel.

SUMMARY

Further, the limiting assembly includes a limiting snap, a base and two symmetrically arranged supports;

• • the supports being arranged on the base;
  • a side of the support away from the base being provided with a groove for supporting the spring, and the spring being capable of being embedded in the groove;
  • an installation notch being formed between the two supports, and the limiting snap being arranged opposite to the installation notch, so that the limiting snap, the two supports and the base form the rotating cavity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

In order to explain the technical contents, the objects, and the effects of the present disclosure in detail, the embodiments will be described below with reference to the accompanying drawings.

Referring to FIGS. 1 to 9, a down lamp includes a lamp body 1 and an elastic assembly 2. The lamp body 1 is provided with at least two symmetrically arranged elastic assemblies 2 in a radial direction. The elastic assembly 2 includes a limiting assembly 21 and a spring 22. The limiting assembly 21 is provided with a rotating cavity 211. A fixing end of the spring 22 is rotatably embedded in the rotating cavity 211, so that a flip angle α of a movable end of the spring 22 ranges from 0° to 90°.

It can be understood that, according to the present disclosure, a rotating cavity 211 is formed in the limiting assembly 21, and the fixing end of the spring 22 is embedded in the rotating cavity 211, so that the movable end of the spring 22 can be flipped over between 0° and 90° relative to the fixing seat 212 with the fixing end of the spring 22 as a rotating fulcrum, as a result, the position of the movable end of the spring 22 can be changed at a larger angle, the flexibility is improved, and the assembly difficulty is reduced.

In some embodiments, the spring 22 includes a first elastic arm 221, a second elastic arm 222, and a rotating connection portion 223; the first elastic arm 221 and the second elastic arm 222 are connected via the rotating connection portion 223, and an obtuse angle is formed between the first elastic arm 221 and the second elastic arm 222; the rotating connection portion 223 is reversibly embedded in the fixing seat 212. The first elastic arm 221 and the second elastic arm 222 are provided to maintain a close connection relationship with the Halo barrel 3, and the rotating connection portion 223 is provided, on the one hand, to connect the first elastic arm 221 and the second elastic arm 222, and on the other hand, to relatively rotatably connect the rotating cavity 211, so as to drive the first elastic arm 221 and the second elastic arm 222 to flip over, thereby achieving the adjustment of the installation angle of the first elastic arm 221 and the second elastic arm 222. Particularly, the flip angle of the movable end of the spring 22, i.e., the flip angle which can be achieved by the plane formed by the first elastic arm 221 and the second elastic arm 222, can make both the springs 22 lie on the same plane, and during the installation process, one of the springs 22 can be firstly embedded in the Halo barrel 3, and then the other spring 22 is loaded, thus reducing the assembly difficulty. In addition, since the angular adjustable range of the first elastic arm 221 and the second elastic arm 222 is large, the 5-inch and 6-inch Halo barrel 3 can be adapted, which has a wide application range.

In some embodiments, the rotating connection portion 223 includes a torsion portion 2231 and a U-shaped connection portion 2232; a first end and a second end of the torsion portion 2231 are respectively connected to the first elastic arm 221 and the second elastic arm 222; a third end and a fourth end of the torsion portion 2231 are respectively connected to two ends of the U-shaped connection portion 2232; the U-shaped connection portion 2232 is reversibly arranged in the fixing seat 212, and the U-shaped connection portion 2232 is relatively rotatably embedded in the rotating cavity 211. The first elastic arm 221 and the second elastic arm 222 are rotatably connected to the rotating cavity 211 via the U-shaped connection portion 2232, so as to obtain a larger flip space, to improve flexibility and to expand the reversible angular range.

By the cooperation of the fixing seat 212 and the limiting member 213, a rotating cavity 211 is formed between the two so as to limit the spring 22, thereby improving the stability of the spring 22 and ensuring that the movable end of the spring 22 can be stably flipped over.

In some embodiments, the fixing seat 212 includes a first side 2121, a second side 2122 and a third side 2123 arranged in sequence; and a relief notch 2131 is formed between the limiting member 213 and the first side 2121 and the third side 2123 of the fixing seat 212, respectively, for the spring 22 to flip over, thereby improving the reliability and flexibility of the spring 22 to flip over.

In some embodiments, the limiting member 213 includes a main body 2132 and a limiting block 2133; the limiting block 2133 is connected to the main body 2132 and is arranged opposite to the second side 2122 of the fixing seat 212; a lower end of the limiting block 2133 is provided with an extension portion, the extension portion and a bottom wall of the fixing seat 212, and a side wall of the main body 2132 opposite to the second side 2122 and the second side 2122 form a rotating cavity 211, so that the portion of the spring 22 is limited in four directions in the circumferential direction, improving the stability of the portion of the spring 22.

In some embodiments, the relief notch 2131 is provided with a stopper 23, and when the spring 22 is pressed against the stopper 23, an included angle formed between a plane where the spring 22 is located and a bottom of the fixing seat 212 ranges from 20° to 60°, i.e., an included angle formed between the plane where the spring 22 is located and the axial end face of the lamp body 1 ranges from 20° to 60°. The stopper 23 is configured to limit the flip angle α of the spring 22 so that the spring 22 does not lie completely flat with respect to the lamp body 1 to satisfy various demands of the user. Optionally, the angle is 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°.

In some embodiments, the limiting assembly 21 includes a limiting snap 214, a base 215 and two symmetrically arranged supports 216; the supports 216 are arranged on the base 215; a side of the support 216 away from the base 215 is provided with a groove 2161 for supporting the spring 22, and the spring 22 is capable of being embedded in the groove 2161; an installation notch 217 is formed between the two supports 216, and the limiting snap 214 is arranged opposite to the installation notch 217, so that the limiting snap 214, the two supports 216 and the base 215 form the rotating cavity 211.
