DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example

[0026] See Figures 1 to 4 As shown, an ultra-thin downlight structure includes a face ring 1 and a shell 2. In this embodiment, the thickness of the face ring is 1-2 cm, and the height of the shell is also relatively small, between 5-10 cm. During assembly, the overall height is relatively small, thereby achieving the effect of an ultra-thin downlight and meeting the usage requirements of different situations. A light source board 3 is fixed in the shell, and a circular cavity 4 with an opening on the bottom is provided in the shell, and the light source board is fixed on the top wall of the circular cavity; a convex ring 5 is integrally formed at the bottom of the inner wall of the circular cavity; in this embodiment, the height of the convex ring can be set as needed, and it is mainly used to install a limiting lens panel and enable the lens panel to rotate in the circular cavity.

[0027] In this embodiment, a lens panel 6 is provided on the bottom surface of the shell, a spherical convex lens 7 is integrally formed at the center of the bottom surface of the lens panel, a lamp cup 8 is integrally formed on the top surface of the lens panel, and the spherical convex lens is located at the end face of the lamp cup; in this embodiment, the lamp cup can focus light during assembly to prevent light from overflowing, and improve the lighting effect through the spherical convex lens, and its integral molding improves processing efficiency and ensures stability and reliability in use.

[0028] In actual application, the top edge of the lens panel is integrally formed with a convex edge 9, and the top edge of the convex edge is provided with locking protrusions 10 at equal intervals, and the outer side of the locking protrusion is provided with a snap protrusion 11; during assembly, the lens panel is placed in the circular cavity, and the snap protrusion is fixed on the top surface of the convex ring, and the snap protrusion can rotate on the convex ring; the top surface of the lamp cup is attached to the top wall of the circular cavity, and the lamp beads of the light source board are placed in the lamp cup. Through the above structure, the effectiveness and convenience of assembly can be improved. The snap protrusion is small, so when the external force is greater than the resistance between the snap protrusion and the locking protrusion, the snap protrusion can enter the circular cavity and realize a snap connection with the locking protrusion, and can be rotated.

[0029] In actual use, the top surface of the face ring is provided with two support protrusions 18. During assembly, the inner wall of the support protrusion is provided with a U-shaped groove 12. The symmetrical outer wall of the housing is integrally formed with a boss 13, and the outer wall of the boss is provided with an annular groove 14. The support protrusion is mainly used to install the boss and the spring, which facilitates the rotation angle of the housing and also facilitates installation in the corresponding installation position. During assembly, the boss is clamped on the support protrusion, and the symmetrical side walls of the U-shaped groove are clamped into the annular groove to limit the position.

[0030] In actual use, a mounting spring 15 is inserted into the support protrusion. This mounting spring is a conventional structure in the prior art and is simply used for simple application. It can be connected by plugging or screwing. A trumpet-shaped groove 16 is provided at the center of the bottom surface of the face ring; the diameter of the lens panel matches the top diameter of the trumpet-shaped groove. This not only enhances the decorative effect, but also improves the lighting effect.

[0031] A connecting wire 17 connected to the light source board is fixed to the side of the housing, which can reduce the impact of the connecting wire on the overall height.

[0032] The present invention has positive effects: the structure of the present invention is reasonably arranged, a circular cavity is arranged on the bottom surface of the shell, a convex ring is arranged on the bottom of the inner wall of the circular cavity, and a spherical convex lens is integrally formed on the lens panel to match the lamp cup, and has a convex edge and a snap-on convex point, and the installation limit is achieved by the snap-on convex point and the convex ring, and the lens panel can be rotated in the circular cavity, which is beneficial to improving the use effect, and the overall structure can be made thinner, so as to meet the installation requirements of different heights, improve its scope of application, and have strong practicality. At the same time, it cooperates with the supporting protrusion through the convex column. After assembly, the shell can be adjusted in angle with the convex column as the fulcrum, and cooperates with the rotatable lens panel, which is beneficial to improving the stability of use and meeting the illumination requirements of different situations, and has strong practicality.

[0033] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0034] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
