Description

Technical Field

[0001] The utility model relates to the technical field of LED, in particular to a flexible wall washer lamp with a continuous lens device. Background Art

[0002] As Figure 1 shown, a diagram of the lamp board structure of an existing flexible wall washer lamp belt is shown. It includes an FPCB lamp board 1', and the FPCB lamp board 1' is provided with a light source 2' and other components. An optical lens 3' is arranged on the light source 2'. The FPCB lamp board 1' is flexible and can be bent and used in a specific direction;

[0003] Figure 2 It is a flexible wall washer lamp belt adopting the lamp board structure in Figure 1 . Specifically, on the basis of Figure 1 , a layer of light-shielding silica gel or other polymer plastics 4' and a light-transmitting silica gel or other polymer plastic sheet 5' are coated. The light source 2' on the FPCB lamp board 1' emits light forward through the optical lens 3', thereby forming a flexible wall washer lamp belt capable of emitting light;

[0004] Among them, in actual manufacturing, gaps will be formed between the light-transmitting silica gel or other polymer plastic sheet 5', the light-shielding silica gel or other polymer plastics 4' and the optical lens 3'. When the product is lit and bent during use, problems such as inconsistent light color and surface bulging are likely to occur;

[0005] Similarly, when the lamp belt is bent and used, it can only be bent and used in a specific direction, that is, the FPCB lamp board 1' is bent when it has the same displacement on the same vertical plane. Such use is reasonable for the lamp belt; if it is bent in another direction (horizontal), that is, when used asymmetrically, the double-layer FPCB lamp board 1 will be subjected to different stress actions, one side is compressed and the other side is stretched. When the bending force is large enough during its use, there is a risk that the FPCB lamp board 1' will be torn or broken, resulting in product failure.

[0006] Therefore Figure 1 and Figure 2 the existing such lamp belt products shown have the following defects:

[0007] Its manufacturing process is relatively complex. The optical lenses need to be installed and fixed one by one, and the labor cost is high;

[0008] The optical lenses are prone to looseness after being subjected to external forces;

[0009] It is difficult to achieve small-sized products;

[0010] It is limited to be bent and used in one direction. Content of the Utility Model

[0011] The technical problem to be solved by the present utility model is to provide a flexible wall - washing lamp, which is easy to manufacture, easy to achieve a small size, can be bent in multiple directions, and has a low cost.

[0012] As one aspect of the present utility model, there is provided a flexible wall - washing lamp, which at least includes:

[0015] A PCB lamp board, which is arranged under the lens - hole - structured member, and on which a plurality of LED light sources are arranged, and the light - emitting direction of each LED light source faces the lower end of a lens hole;

[0016] An insulating glue layer, which wraps the lens - hole - structured member and the PCB lamp board, and is fixed to the strip - shaped lens sheet.

[0017] Preferably, the lens - hole - structured member is made of a flexible material, the lens holes are through - holes penetrating its upper and lower end faces, and the cross - section of the through - hole is square, triangular, elliptical, circular or polygonal.

[0018] Preferably, the strip - shaped lens sheet is made of a light - transmissive soft material, and the insulating glue layer is made of a light - shielding soft material.

[0019] Preferably, the PCB lamp board is a long - strip FPCB lamp board, on which a plurality of LED light sources are arranged at intervals.

[0020] Preferably, the PCB lamp board includes a plurality of single - piece PCB boards arranged at intervals, and at least one LED light source is arranged on each single - piece PCB board; two bendable connection jumpers are used to connect between two adjacent single - piece PCB boards.

[0021] Preferably, the connection jumper is a curve, a wavy - shaped structure jumper or a spiral - spring - shaped structure jumper.

[0022] Implementing the embodiments of the present utility model has the following beneficial effects:

[0023] The present utility model provides a flexible wall - washing lamp, which includes: a strip - shaped lens sheet, a lens - hole - structured member, a PCB lamp board and an insulating glue layer. The PCB lamp board is made of an integral flexible FPCB lamp board or connected by multiple PCB boards, and the strip - shaped lens sheet, the lens - hole - structured member and the insulating glue layer are all made of soft materials. Therefore, the flexible wall - washing lamp can be bent in multiple directions;

[0024] At the same time, since the lens holes are pre-formed in the lens hole structure member, there is no need for manual installation of the lens during installation. Through automated machine production, the labor cost is effectively reduced; and continuous length applications can be achieved, and smaller size product development applications can also be realized.

Further, the lens holes 20 arranged on the lens-hole structure member 2; the lens-hole structure member 2 is made of a soft material with a certain elasticity, and can be soft rubber materials such as silica gel, PU, PVC, etc.; due to the use of a soft material, the lens-hole structure member 2 can be bent for use (as Figure 7 shown);
