Description

Technical Field

[0001] The utility model relates to the technical field of light strips, in particular to a 3D light strip. Background Art

[0002] LED light strips are generally divided into two types: flexible LED light strips and LED hard light strips. LED hard light strips are easier to fix, convenient for processing and installation, but cannot be bent at will. Flexible LED light strips use FPC as the assembly circuit board and are assembled with chip LEDs, so that the LED light strip can be bent, folded, and wound at will. Since the FPC is tightly wrapped in a plastic casing, when external force applies torsional stress along the thickness direction of the circuit board, the circuit board itself cannot withstand a large degree of rotation, which will cause the circuit board to be torn off by external force.

[0003] When installing and using existing flexible LED light strips, attention must be paid to the bending direction. Usually, the FPC board and the SMD LED are placed horizontally, and only top bending can be achieved, but side bending cannot be achieved, which is not convenient for meeting the different needs of customers.

[0004] Therefore, how to achieve both top bending and side bending of the LED light strip has become a focus of attention of those skilled in the art and related personnel. Utility Model Content

[0007] Preferably, the light-emitting component includes an FPCB board and a plurality of LED lamps. The FPCB board is arranged on the bottom wall of the installation cavity and is arranged obliquely with respect to the opening of the installation cavity. The plurality of LED lamps are all arranged on the FPCB board.

[0008] Preferably, the light emitting assembly further comprises a PET support plate, the PET support plate is arranged on the bottom wall of the mounting cavity and is arranged obliquely with respect to the opening of the mounting cavity, and the FPCB board is arranged on the PET support plate.

[0009] Preferably, an inclined mounting groove is provided at the connection between a side wall and a bottom wall of the mounting cavity, the PET support plate and the FPCB board are both installed in the mounting groove, and the plurality of LED lamps are exposed in the mounting groove.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figures 1 to 4 The embodiment of the utility model proposes a 3D light strip, which can be bent top and side according to actual needs, so as to be transformed into the shape required by the customer, so as to be applied to different scenes, including a shading member 1, a light-transmitting member 2 and a light-emitting component 3. The shading member 1 is provided with a mounting cavity 11 with an upper opening, the light-transmitting member 2 covers the opening of the mounting cavity 11, and the outer surface of the light-transmitting member 2 is flush with the upper end of the shading member 1, thereby closing the mounting cavity 11 to facilitate the emission of light emitted by the light-emitting component 3. The light-emitting component 3 is tilted at the lower end of the mounting cavity 11, and the tilt angle is between thirty degrees and forty-five degrees. The light emitted by the light-emitting component 3 is emitted to the side wall of the mounting cavity 11, and the light is reflected to the light-transmitting member 2 by the reflection of the side wall of the mounting cavity 11, and is emitted through the light-transmitting member 2.

[0027] Reference Figure 2 and Figure 4The light-emitting component 3 includes an FPCB board 31, a PET support board 32 and multiple LED lamps 33. The FPCB board 31 is arranged on the PET support board 32. The FPCB board 31 and the PET support board 32 have the same shape. The FPCB board 31 is supported by the PET support board 32 to enhance the bending resistance of the light-emitting component 3 to prevent the FPCB board 31 from breaking, thereby improving the durability of the self-shaped 3D light strip. Multiple LED lamps 33 are all arranged on the FPCB board 31, and the multiple LED lamps 33 are arranged at equal intervals. The PET support board 32, the FPCB board 31 and the LED lamps 33 are installed to form a whole, and then inserted into the opening of the bottom wall of the installation cavity 11, and are arranged obliquely with the opening of the installation cavity 11, so as to facilitate the bending of the 3D light strip.

[0028] Reference Figure 2 and Figure 3 The mounting cavity 11 includes an upper mounting cavity 111 and a lower mounting cavity 112. The lower end of the upper mounting cavity 111 is connected to the upper end of the lower mounting cavity 112. The upper end of the upper mounting cavity 111 is open to facilitate light to pass through.

[0029] Reference Figure 2 and Figure 3 A mounting groove 113 is provided at the connection between a side wall and the bottom wall of the lower mounting cavity 112. The mounting groove 113 is in the shape of a rectangular parallelepiped. The FPCB board 31 and the PET support board 32 are both mounted in the mounting groove 113. Multiple LED lamps 33 are exposed in the mounting groove 113 to facilitate the emission of light from the LED lamps 33. The mounting groove 113 is tilted, and there is a certain angle between the mounting groove 113 and the bottom wall of the lower mounting cavity 112, so that there is a certain angle between the FPCB board 31 and the LED lamps 33 and the bottom wall of the lower mounting cavity 112. When the 3D light strip is bent sideways, the side of the light-emitting component 3 is prevented from being damaged due to excessive bending.

[0030] Reference Figure 2 and Figure 3 The connection between the other side wall of the lower mounting cavity 112 and the bottom wall is in an arc shape, so that the light emitted by the LED lamp 33 is reflected upward, so that the light emitted by the LED lamp 33 is emitted through the light-transmitting member 2.

[0031] Reference Figure 2 and Figure 3 A light-transmitting groove 21 is provided on the light-transmitting member 2, and the width of the light-transmitting groove 21 is the same as the upper end of the lower mounting cavity 112, so that there is a certain gap between the LED lamp 33 and the light-transmitting member 2, so that the light emitted by the light-transmitting member 2 is more uniform.

[0032] Reference Figure 2The top wall of the light-transmitting groove 21 protrudes downward to form a focusing portion 22, and the focusing portion 22 is in a semicircular arc shape. The light emitted by the LED lamp 33 reaches the focusing portion 22 to change the angle of the light and make the light more concentrated.

[0033] Reference Figure 2 and Figure 3 The width of the upper mounting cavity 111 gradually increases from bottom to top, and the light-transmitting member 2 has the same shape as the upper mounting cavity 111 , so that the light emitted by the LED lamp 33 is emitted more evenly through the light-transmitting member 2 .

[0034] Reference Figure 1 The light-transmitting member 2 and the light-shielding member 1 are integrally formed, and the light-transmitting member 2 is made of transparent glue, and the light-shielding member 1 is made of light-shielding glue, and both the light-transmitting member 2 and the light-shielding member 1 are made of flexible waterproof material, which facilitates the top bending and side bending of the customized 3D light strip, and can better meet the different installation needs of customers, making the use scenarios more extensive.

[0035] Reference Figure 1 The light-emitting surface of the light-transmitting member 2 is in a honeycomb shape, and the honeycomb-shaped light-emitting surface can better control the direction and angle of the light, and effectively eliminate the edge stray light that appears after the LED lamp 33 emits light, so that the light color of the self-shaped 3D light strip is purer and the light efficiency is higher.

Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
