[0002] An LED strip light refers to assembling LEDs on a strip-shaped FPC (flexible printed circuit board) or a rigid PCB board. Due to its long lifespan, energy-saving, and environmental protection characteristics, LED strip lights are increasingly widely used in the decoration industry. With the popularization of LED light sources, the market has more specific requirements for the application and light-emitting angle of LEDs in different environments. An LED strip light that is convenient to bend and shape, can achieve more light-emitting angles to match different scenarios and usage environments, and can improve the light-emitting effect of the product can well meet the requirements.

[0003] Existing flexible LED strip lights generally use omnidirectional planar lighting. This method cannot precisely control the light-emitting angle, resulting in light scattering, insufficient concentration, causing waste of light efficiency. And because the light-emitting angle cannot be adjusted, its usage scenarios are limited and it is difficult to meet the needs of users. For conventional side-emitting rigid strip lights, due to the hardness limitation of the strip light, many shapes cannot be satisfied, and the light uniformity will be severely affected. The limitation of the rigid board makes the waterproof effect of the rigid strip light not ideal, there are certain usage risks, and the manufacturing cost has no advantage compared with that of LED flexible strip lights. In view of the above situation, the utility model proposes a side-emitting LED lens strip light that can be bent arbitrarily to overcome the deficiencies in current practical applications.

[0021] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0023] As Figures 1-3 shown, a side-emitting LED lens light strip capable of being arbitrarily bent provided by an embodiment of the present utility model includes a flexible circuit board 1, an LED lamp bead 2, a resistor 3, an optical lens 4, and a wiring terminal 5;

[0024] The flexible circuit board 1 is designed with an uneven shape, and the concave and convex positions of any two LED light strips completely coincide, forming a complementary relationship;

[0025] The flexible circuit board 1 is provided with lens positioning holes, screw hole positions, LED lamp bead pads, resistor pads, and wiring terminal pads. The lens positioning holes are used to connect the optical lens 4; the screw hole positions are used to use screws to firmly fix the light strip on the surface of an object; the LED lamp bead pads are used to connect the LED lamp beads 2; the resistor pads are used to connect the resistors 3; the wiring terminal pads are used to connect the wiring terminals 5; the flexible circuit board 1 is also provided with positive and negative connection pads, which are used to connect an external power supply and repair and splice flexible light strips;

[0026] The LED lamp bead 2 is used to convert electrical energy into light energy;

[0027] The resistor 3 acts on the flexible circuit board 1 and is used to control the current and protect the safety of the flexible circuit board 1;

[0028] The optical lens 4 is used to adjust the light-emitting angle of the LED lamp bead 2, and different light-emitting angle lenses are used to match different scenarios and usage environments to improve the light-emitting effect of the product;

[0029] The wiring terminal 5 is used to insert a matching wire terminal, facilitating power connection, with a wire-free welding design, reducing the professional requirements for wire welding.

[0030] In the embodiment of the present utility model, through the uneven external shape design, it is convenient to bend the LED light strip on a plane. The LED lamp bead 2, the resistor 3, the optical lens 4, and the wiring terminal 5 are welded at the convex positions, so that the width of the LED light strip can be made narrower without affecting the convenience of bending. Except for the LED lamp bead 2, the resistor 3, the optical lens 4, and the wiring terminal 5, the number of LED light strips that can be made on the same area of material can be increased by about 30%, greatly reducing the product cost.

[0033] As Figure 1 and Figure 2 shown, as a preferred embodiment of the present invention, a double-sided adhesive 6 is pasted on the back of the flexible circuit board 1, and the double-sided adhesive 6 is used to paste the light strip on the surface of the required object. The double-sided adhesive 6 is a double-sided acrylic adhesive, a heat-conducting adhesive or a heat-dissipating aluminum adhesive.

[0034] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
