This disclosure generally relates to the technical field of lighting fixtures, and more particularly, to a split-type ceiling lamp.
A ceiling lamp is a kind of lighting fixture, which has a comparatively flat upper portion and a bottom completely attached to the ceiling during installation. The light source adopted in the ceiling lamp may be an incandescent light, a fluorescent light, a high-intensity gas-discharge light, a halogen tungsten light or an LED light, etc. Presently, LED ceiling lamps are the most popular ones sold on the market, which are widely used in homes, offices and entertainment places, etc.
Conventional ceiling lamps normally include two detachable parts: a lamp cover and a lamp body, wherein the lamp body is directly fixed on the ceiling using screws, and the lamp cover is clamped with the lamp body for covering it. The shortcoming of the aforesaid structure is: the lamp body fixed on the ceiling makes the disassembly troublesome, resulting in difficult replacement and maintenance of the light source. Meanwhile, the light source and other components on the lamp body increase the weight of the lamp body, making the fixation of the lamp body on the ceiling more inconvenient. As a result, the fixation and installation of the ceiling lamp are laborious and cannot be completed by one person.
The purpose of the present disclosure is to provide a split-type ceiling lamp.
To achieve the above purpose, the present disclosure adopts the following technical solution: a split-type ceiling lamp comprising a lamp body, a diffusion cover and a base, wherein one side of the lamp body is provided with an electric apparatus groove, and the other side of the lamp body is provided with a mounting groove, wherein a light source is fixedly mounted in the electric apparatus groove, and the diffusion cover is clamped with the lamp body and covers the electric apparatus groove, wherein one side of the base is embedded in the mounting groove, and the other side of the base is provided with a wiring terminal, which is electrically connected to the light source through a power coupling module, wherein the power coupling module further comprises a socket portion mounted in the mounting groove and a connector portion mounted on the base, wherein the socket portion is connected to the light source, the connector portion is connected to the wiring terminal, and the base is clamped with the lamp body.

The light source comprises a positive electrode connecting wire and a negative electrode connecting wire, wherein the positive electrode connecting wire is connected to a positive electrode conductive elastic sheet, and the negative electrode connecting wire is connected to a negative electrode conductive elastic sheet. One end of the positive electrode conductive elastic sheet is fixed in the electric apparatus groove, and the other end of the positive electrode conductive elastic sheet extends into the inner inserting hole through the inner arc-shaped through hole after being bent. One end of the negative electrode conductive elastic sheet is fixed in the electric apparatus groove, and the other end of the negative electrode conductive elastic sheet extends into the outer inserting hole through the outer arc-shaped through hole after being bent. The base is matched with the mounting groove, and a circular inserting groove is formed in the middle of one side of the base which is embedded in the mounting groove. The circular inserting groove is internally fixed with an outer conductive ring and an inner conductive ring, wherein the outer conductive ring, the inner conductive ring, and the circular groove are coaxially arranged. A plurality of through holes are formed in the bottom of the circular inserting groove. One end of the outer conductive ring and one end of the inner conductive ring are respectively provided with a plurality of pins, and the pins are in one-to-one correspondence with the through holes.
