Description

A multi-strip combined LED lamp

technical field

The utility model relates to the field of LEDs, in particular to an LED lamp group formed by combining a plurality of strip-shaped LED lamp tubes. the

Background technique

With the improvement of living standards in modern society, people's requirements for various necessities also increase. A plurality of combined LED lamps are mainly manufactured for the purpose of showing more gorgeous, beautiful and enhancing lighting brightness. However, for general LED lamps, since each LED lamp is arranged on a different PCB board, each PCB Due to the unreasonable layout of the board, the heat generated is too large during operation, and the heat cannot be discharged from the inside in time, resulting in poor heat dissipation. Long-term overload work is one of the reasons for the low service life of existing multi-combination LED lamps, and its heat dissipation problem has become one of the key points that need to be solved urgently. the

Utility model content

The technical problem to be solved by the utility model is to provide an LED lamp which can freely combine the number of LED lamp tubes, detach the LED lampshade, facilitate LED maintenance, and improve heat dissipation efficiency through air convection. the

Achieve the above-mentioned purpose through the following technical solutions:

A multi-strip combined LED lamp, including a heat dissipation structure, a lampshade, a PCB board, LEDs, a power control module and a lamp holder, the PCB board is arranged on the heat dissipation structure, and the PCB board is evenly distributed with the LED, the heat dissipation structure is connected to the lamp holder, the power supply control module is arranged in the lamp holder, the heat dissipation structure includes more than three heat sinks, the lampshade is an arc lampshade strip, and each One side of the heat sink is covered by an arc lampshade strip.

The two sides of the heat sink are provided with grooves for fastening the lampshade. A PCB board is arranged on one side of the heat sink, and the LEDs are evenly distributed on the PCB board. The radiating fins enclose a cylindrical structure, and gaps are left between the radiating fins. The upper part of the column structure is covered by an upper cover with air holes, and the lower part of the column structure is connected to the lamp head through a fixed ring lamp. the

The beneficial effects of the utility model are: each cooling fin of the utility model cooperates with a lampshade bar to form an independent light-emitting unit, and each cooling fin is surrounded by the same central point, forming a polyhedron structure. Since the heat generated on each heat sink is roughly the same, it dissipates heat through the back of the heat sink, and outputs it through the vent hole of the upper cover. The overall heat dissipation efficiency makes the operating environment of the LED lamp more stable. Each PCB board is arranged around a central point, which can flexibly increase or decrease the number of LED light tubes, so as to properly adjust the position of the light source point and the irradiation angle in the lighting. the

Detailed ways

Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described, and it should be noted that, the directional term mentioned in the following embodiment, for example " up, down, left, right " only refers to the direction of accompanying drawing, therefore , the directional terms used are used for illustration and are not intended to limit the utility model. the

As shown in Figures 1-2, a multi-strip combined LED lamp includes a heat dissipation structure 6, a lampshade, a PCB board, LEDs, a power control module 2 and a lamp holder 1, and the heat dissipation structure 6 is provided with the PCB board, the LEDs are evenly distributed on the PCB, the heat dissipation structure 6 is connected to the lamp holder 1, the power control module 2 is arranged in the lamp holder 1, and the heat dissipation structure 6 includes more than three As for the heat sink, the lampshade is an arc-shaped lampshade strip, and one side of each heat sink is covered by an arc-shaped lampshade strip. the

The two sides of the heat sink are provided with grooves for fastening the lampshade. A PCB board is arranged on one side of the heat sink, and the LEDs are evenly distributed on the PCB board. The radiating fins enclose a cylindrical structure, and gaps are left between the radiating fins. The upper part of the column structure is covered by a cover 5 with air holes 7, and the lower part of the column structure is connected with the lamp holder 1 through a fixing ring 3. the

Each cooling fin of the utility model cooperates with a lampshade bar to form an independent light-emitting unit, and each cooling fin is surrounded by the same central point, showing a polyhedron structure. When in use, the heat sink can be fixed on the fixed ring 3, but a certain gap should be reserved between the heat sinks, and then the arc lampshade is respectively snapped on each heat sink, and finally the upper cover 5 is installed on the top. The heat formed on the chip is roughly the same, and it dissipates heat through the back of the heat sink, and outputs it through the vent hole 7 of the upper cover 5. At the same time, the gap left between the two LED tubes that emit light can also dissipate heat, improving the overall performance. Excellent heat dissipation efficiency makes the operating environment of LED lights more stable. Each PCB board is arranged around a central point, which can flexibly increase or decrease the number of LED lamp groups, so as to properly adjust the position of the light source point and the irradiation angle in the lighting. the
