Description

Spliced preassembled down lamp Technical Field The invention relates to the technical field of down lamps, in particular to a spliced preassembled down lamp. Background Preassembled down lamps, also called borderless down lamps, have become the mainstream lighting choice for home, business space and other scenes by virtue of the lighting effect of 'invisible light'. The down lamp adopts an embedded mounting mode generally and comprises a pre-mounted plate and a lamp body structure composed of a radiator, a light source module, a lens and an anti-dazzle cover, wherein during mounting, the lamp body is fixed through fastening cooperation of the pre-mounted plate and a suspended ceiling, and the lamp body and the suspended ceiling surface are perfectly fused after mounting, so that visual cutting of a space top surface by a traditional lamp can be effectively avoided. In the decoration design without a main lamp, the splicing installation application of a plurality of preassembled down lamps is wide, and the whole luminous area is formed by combining a plurality of lamps so as to meet the basic lighting requirement under the design scene. In the prior art, the splicing mode of the multi-tube lamps depends on independent installation of adjacent pre-assembled plates. In order to ensure the installation stability of each down lamp, the preassembled plate needs to keep enough contact area with the suspended ceiling and is provided with a plurality of groups of fastening structures, but the structural design of the preassembled plate directly limits the reduction of the distance between two adjacent down lamps, the excessive lamp distance can lead to the ineffective connection of illumination of the adjacent down lamps and is difficult to form a continuous surface light source, in addition, the lack of an adaptive positioning structure between the adjacent preassembled plates and between adjacent lamp bodies can lead to the occurrence of installation dislocation when the plurality of down lamps are spliced, so that the plurality of down lamps are not on the same straight line, further the problem of uneven luminous edges is caused, the overall texture of space illumination is reduced, and the requirements of the spliced down lamps on continuous, uniform and tidy illumination can not be met. It can be seen that there is a need for improvements and improvements in the art.
