Problems solved by technology

[0003] The structure of LED ceiling lamps in the prior art is mostly composed of a lampshade, a chassis, and an LED lamp. The LED lamp is installed on a circuit board with a large area. However, the specifications of the LED lamp with this structure are fixed and cannot be flexibly configured. The utilization rate is not high, more scraps are produced, the cost is high, energy saving and heat dissipation are poor; the latest ceiling lamps use LED lamps, that is, LED patch lamps, which are made of FPC circuit boards, LED lamps, and high-quality silicone sleeves. , has the advantages of uniform light output, no halo, high luminous efficiency, energy saving and environmental protection, etc. However, the electrical connection between each LED light piece is still through welding wires, especially for larger ceiling lights that use multiple LED light pieces. Assembly The process is very complicated, the cost is high, and too many wires occupy a lot of internal space, which makes the overall heat dissipation performance of the LED lamp poor

Embodiment Construction

[0039] The present invention will be further described in conjunction with the following examples and accompanying drawings.

[0040] A kind of LED ceiling lamp of the present invention, as Figure 1 to Figure 9 As shown, it includes a lampshade 1, a chassis 2, a power supply PCB3 arranged in the middle of the chassis 2, and eight strip-shaped LED light sheets 4 arranged on the chassis 2. The LED light sheets 4 are radially distributed on the chassis 2 from the center to the surrounding direction. The power supply PCB3 is electrically connected to the LED light sheet 4 through the power line. A power supply cover 5 is arranged above the power supply PCB3. Eight metal connecting pieces 6 are arranged between the power supply cover 5 and the chassis 2. The adjacent LED light pieces 4 are connected by metal. The sheet 6 is electrically connected, and the metal connecting sheet 6 is fixedly connected to the power supply cover 5 and the chassis 2 respectively.

Abstract

The present invention relates to the technical field of LED lamps, in particular to an LED ceiling lamp. connection, a power supply cover is provided above the power supply PCB, and several metal connection pieces are provided between the power supply cover and the chassis. The metal connection pieces include a first connection end and a second connection end, and the first connection end and the second connection end are respectively It is in contact with the welding pad at the end of the corresponding LED light sheet. Compared with the prior art, the LED light pieces of the present invention are electrically connected through metal connecting pieces, which greatly simplifies the assembly process of the LED ceiling light, reduces the production cost, and has good heat dissipation performance.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED ceiling lamp. Background technique [0002] As a commonly used lamp, the ceiling lamp is installed inside the room. Because the upper part of the lamp is relatively flat and installed close to the roof, it seems to be adsorbed on the roof, so it is called a ceiling lamp. [0003] The structure of LED ceiling lamps in the prior art is mostly composed of a lampshade, a chassis, and an LED lamp. The LED lamp is installed on a circuit board with a large area. However, the specifications of the LED lamp with this structure are fixed and cannot be flexibly configured. The utilization rate is not high, more scraps are produced, the cost is high, energy saving and heat dissipation are poor; the latest ceiling lamps use LED lamps, that is, LED patch lamps, which are made of FPC circuit boards, LED lamps, and high-quality silicone sleeves. , has the advantages of uniform light ou...
