Description

Easy disassembly and assembly of disc-shaped LED lights

technical field

The invention relates to a decorative lamp using LED as a light source, in particular to a disc-shaped LED lamp which is easy to assemble and disassemble.

Background technique

Because LED has the advantages of high light efficiency, low energy consumption and long life, it has been widely used in various decorative occasions, advertising industry and night indication lighting, such as for decoration of windows, showcases, indoor scenery, etc., as well as for For night lights, etc. Because of the special requirements of these usage occasions, it is generally desired that the decorative lamps used have a beautiful appearance, or even be small and delicate, and the decorative lamps using LEDs as light sources can fully meet such requirements. An existing disc-shaped LED lamp is in the shape of a thin disc with a very delicate and small appearance, and can be used for both decoration and night-time indicator lighting. Its structure is: it has a circuit board, a lampshade and a lamp holder, the light-emitting element LED is mounted on the circular circuit board, and the lower part of the disc-shaped lampshade is provided with a concave part adapted to the shape of the circuit board. The board is embedded in the concave part of the lampshade, and the upper part of the disc-shaped lamp holder is provided with a concave cavity adapted to the lampshade. Adaptation is achieved by setting convex points on the outer wall of the lampshade and setting corresponding fine limit ribs on the inner wall of the cavity of the lamp holder in an elastic buckle manner; and there are mainly two ways to fix the entire lamp , one is to set adhesive paper on the bottom surface of the lamp holder, and directly stick the lamp on the wall, furniture surface or window surface, etc., and the other is to open a mounting hole on the bottom wall of the lamp holder cavity, and the screw passes through the mounting hole And fix the lamp at the installation place; In addition, in order to consider the problem of disassembly, it usually has a small notch suitable for a flat-blade screwdriver to be inserted on the lampshade or lamp holder, so that the screwdriver is inserted into the notch to pry the lampshade out. In actual use, it is found that it has the following problems: Although it is convenient to install, when it is necessary to displace the lamp or replace damaged lampshades and other accessories, especially when the welding point of the lamp's power cord falls off and needs to be repaired, its To disassemble, a screwdriver needs to be inserted into the notch to pry out the lampshade. On the one hand, the operation is not easy, and on the other hand, the lampshade is easy to pry off. Moreover, setting the notch will inevitably damage the overall appearance of the lamp. Adhesive products seem to be good for shifting operations, but they tend to fall off due to loss of stickiness, and are not helpful for other repairs, replacements, etc.

In addition, in the existing decorative lamps with LED as the light source, the power cord is generally only directly welded to the corresponding conductive contact of the circuit board, without other enhancement measures, and the strength of the soldering and the welding place lose the power cord. The strength of the exposed wires protected by the outer insulating layer is insufficient, and it is easy to break or pull off and fall off during use. In reality, the safety requirements for such electrical appliances are getting higher and higher, especially the European Union and other Strict safety standards have been established, requiring it to withstand a pulling force of 60N, and to withstand 25 consecutive pulls, and the displacement of the wire should not exceed 2mm. In practice, the existing connection mode between the power line and the circuit board cannot meet the above requirements at all, so it is necessary to improve it.

Contents of the invention

The main technical problem to be solved by the utility model is to provide a disc-shaped LED lamp which is very convenient to install and disassemble and has a very tidy appearance in view of the current state of the art.

In order to solve the problems of the technologies described above, the utility model adopts the following technical solutions:

This disc-shaped LED lamp, which is easy to disassemble, has a circuit board, a lampshade, a lamp holder, and a power cord connected to the circuit board. The component LED, the lower part of the lampshade is provided with a concave part that is adapted to the shape of the circuit board, and the circuit board on which the LED is mounted is embedded in the concave part of the lampshade. There are at least two rib-like turnbuckles formed on the inner side wall of the seat cavity, and grooves corresponding to the turnbuckles are formed on the outer sidewall of the lampshade, and an opening is provided at one end of the grooves. In the guide groove on the lower edge of the outer wall of the lampshade, the bottom wall of the cavity of the lamp holder is also provided with an elastic ejection mechanism that can push the circuit board together with the lampshade out of the cavity of the lamp holder.

The elastic ejection mechanism includes at least one piece of elastic sheet arranged on the bottom wall of the cavity of the lamp holder, one end of the elastic sheet is fixedly connected to the bottom wall of the cavity of the lamp holder, and the other end is a free end, and the The free end always has a tendency to protrude upwards from the bottom wall of the cavity of the lamp holder.

The elastic sheet is integrally formed on the bottom wall of the cavity of the lamp holder.

The number of the elastic sheets is two, and they are arranged symmetrically at the bottom of the concave cavity of the lamp holder.

The circuit board is equipped with a clamp that can just pass through the power cord. After the welding end of the power cord passes through the clamp, it is divided into two single wires, and each single wire is bent from the front end of the clamp. Back and close to the outside of the wire fixing clip, then pass through the circuit board from the opening on the circuit board and solder to the soldering point on the circuit board.

The main body of the wire fixing clip is arched, and the two feet on both sides of the arched main body are extended with front and rear clips along the front and back of the wire fixing clip, and the circuit board is provided with the Card slots for the front and rear clips. Corresponding to each foot of the bow-shaped main body, the card slot can be a card slot that can simultaneously accommodate the front card feet and the rear card feet, or it can be individually corresponding to each front card foot and each Two card slots for the rear card feet.

The front clamping feet are longer than the rear clamping feet, so that after the clamping legs of the wire fixing clip are inserted into the slots, the wire fixing clips will not cause the clamping feet to escape from the slots due to the power cord being pulled back.

The utility model has the following beneficial effects: 1. The installation and disassembly are very simple and convenient, except for the overall displacement of the lamp, no need to use tools such as screwdrivers; The pried out notch makes the appearance more neat and beautiful; 3. The power cord is fixed by a wire clamp and has been bent many times, so that there is a great friction between the power cord and the wire clamp, so that the welding The point is no longer the main stress point, so the tensile capacity is greatly enhanced, which can fully meet the strict safety standards of the European Union.
