Embodiments of the invention

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

For the ceiling lamp, since it is difficult to avoid a gap between the lampshade and the chassis, the mosquito easily enters the lampshade, and the corpse adheres to the lampshade to form a black spot that is difficult to clean, which not only affects the appearance but also affects the life of the lamp bead and the power source. .

Referring to FIGS. 1 and 2, the present embodiment provides a double-decked ceiling light comprising a first chassis 10 and a second chassis 20 disposed from top to bottom and a lamp cover 30 fixedly disposed under the second chassis 20. An illumination cavity is formed between the lower bottom surface of the second chassis 20 and the lamp cover 30, and a light source 40 is disposed on the lower bottom surface of the second chassis 20. The driving power source 50 of the light source 40 is fixed on the first chassis 10 or the second chassis 20 or Integrated on the LED light source board. The first chassis 10 can be a hollow structure, which can save material, and the second chassis 20 can be fixed to the lamp cover 30 by screws. The cover body comprises the cover body being a lamp cover or a framed lamp cover that covers the outside of the chassis; the lamp cover is flat or curved, or has a lamp cover on which the decorative accessory is mounted.

The lamp cover 30 is fixed in such a manner that a snap device for fixing to the first chassis 10 is formed on the periphery of the lamp cover 30, or the lamp cover 30 is screwed to the first chassis 10.

In order to achieve pest control, the first chassis 10, the second chassis 20, and the globe 30 may be fixed by the following structure. The lamp cover 30 is a lamp cover or a lamp cover with a frame outside the chassis, and a rib 31 for placing the second chassis 20 is formed on the inner side wall of the lamp cover 30 or the outer frame, in the first chassis 10 A downwardly facing hem 11 is formed on the periphery, and a gap 21 for accommodating the hem 11 is formed between the outer side of the second chassis 20 and the inner side wall of the globe 30. A lamp cover, a lamp cover with a frame or a periphery of the second chassis is formed with a rotary snap for fixing to the first chassis; or the lamp cover is screwed to the first chassis.

With the ceiling lamp of the above structure, the light-emitting cavity formed between the lamp cover 30 and the second chassis 20 and the external space have multiple protections, and the external mosquito enters the light-emitting cavity, and needs to pass through the folded edge of the first chassis 10 in sequence. a gap 21 between the inner side wall of the lamp cover 30, a gap 21 between the bottom edge of the flange 11 of the first chassis 10 and the rib 31 of the lamp cover 30, and the flange 11 and the second chassis of the first chassis 10. The outer side of the 20 greatly improves the difficulty of the mosquito entering the lampshade 30, thereby improving the insect proofing effect of the ceiling lamp.

During the installation process, a wire hole through which the wire passes is required to be opened on the second chassis 20. In order to ensure the insect proof effect in the lampshade 30, the diameter of the wire is equal to that between the wire holes; or a rubber sleeve is placed between the wire and the wire hole; or a sealant is filled between the wire and the wire hole.

In order to facilitate the wiring of the light source 40 on the bottom surface of the second chassis 20, the technical solution provided in this embodiment is fixed with a downward facing first male and female terminal 61 on the lower bottom surface of the first chassis 10, and a top surface of the second chassis 20 A second male and female terminal 62 is fixed to a position corresponding to the first male and female terminal 61. The first male and female terminals 61 are electrically connected to the external wires to facilitate the connection of the zero-fire wires; the second male and female terminals 62 on the second chassis 20 are connected to the first male and female terminals 61 to complete the wiring of the light source 40.

Specifically, the first male and female terminal 61 is located at a lower bottom surface of the first chassis 10 near the rotating block or the periphery, which can reduce the length of the male and female plugs on the second chassis 20, and is easy to see and correct during the installation process. The male and female mothers are inserted.

It is also possible that the first male and female terminal 61 is close to the connection between the first chassis 10 and the lamp cover 30, and is convenient for connecting the male busbar when the first chassis 10 is connected.

It is also possible to have an elastic means for fixing the male busbar under the first chassis 10, or a resilient means for mounting the male busbar on the second chassis 20.

The embodiments described above do not constitute a limitation on the scope of protection of the technical solutions. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the above-described embodiments are intended to be included within the scope of the technical solutions.

Industrial applicability
