[0023] In order to make the content of the utility model easier to understand, the utility model is further described in detail below according to specific embodiments and in conjunction with the accompanying drawings, wherein:

[0024] Figure 1 It is a structural schematic diagram of the utility model.

[0025] Figure numerals: mounting groove 1, light strip body 2, LED light source board 3, first light-transmitting silicone strip 4, second light-transmitting silicone strip 5, irradiation groove 6, arched protrusion 7, inclined convex strip 8, arc-shaped light-incoming surface 9, arc-shaped light-emitting surface 10. DETAILED DESCRIPTION

[0026] 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 in 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. Example

[0027] See Figure 1 A silicone light strip with an optical angle includes a light strip body 2 provided with a mounting groove 1, wherein an LED light source board 3 is provided in the mounting groove. In this embodiment, the light strip body and the LED light source board are conventional structures of the prior art, and their shapes can be processed and set as needed, so they are not described in detail, but simply applied;

[0028] In this embodiment, the first light-transmitting silicone strip 4 and the second light-transmitting silicone strip 5 are sequentially arranged in the installation groove from the LED light source board to the opening; and in actual application, the side of the first light-transmitting silicone strip away from the LED light source board is provided with an irradiation groove 6; in this embodiment, the side of the first light-transmitting silicone strip close to the LED light source board is a plane. The side of the first light-transmitting silicone strip close to the LED light source board is an arc-shaped concave surface or an arc-shaped convex surface. Through the above structure, practicality is improved.

[0029] At the same time, an outwardly convex arched protrusion 7 is provided in the middle of the inner wall of the irradiation groove, and the symmetrical edges of the arched protrusion are all provided with inclined convex strips 8 inclined to the midline of the arched protrusion and used to focus light to the middle; in this embodiment, the number of the inclined convex strips is two or four. And the inclined convex strip is between the arched protrusion and the side wall of the isosceles trapezoid. In actual application, the inclined angle between the inclined convex strip and the midline of the arched protrusion is 10-120 degrees. Through the above structure, the light passing through the first light-transmitting silicone strip can be aggregated to the middle, that is, after the light of the LED light source board is irradiated, when it is on the exit surface, the light will be refracted on the surface of the inclined convex strip, and the light will be aggregated to the middle, achieving the focusing effect of the light-emitting angle. And by the inclination angle of 10-120 degrees, the refracted light becomes 10-120 degrees outward irradiation, thereby changing the light-emitting angle of the light. Through the above structure, different irradiation angles can be achieved by replacing the first light-transmitting silicone strips with different angles, such as 10°, 15°, 90°, and 120°.

[0030] And in the actual application process, the arched protrusion is arranged on the inner wall of the irradiation groove close to the LED light source board; at the same time, the side of the second light-transmitting silicone strip close to the first light-transmitting silicone strip is an outwardly convex arc-shaped light-inlet surface 9; the light of the LED light source board is refracted and concentrated by the inclined convex strip of the first light-transmitting silicone strip and irradiated outward from the second light-transmitting silicone strip. The concentrated light is then refracted by the arc-shaped light-inlet surface and diffused, and then irradiated outward through the second light-transmitting silicone strip, which can make the light more uniform and soft, and not dazzling, which is conducive to improving the lighting effect.

[0031] In this embodiment, the height of the inclined convex strip is less than the depth of the irradiation groove, and a gap is provided between the inclined convex strip and the arc-shaped light-incoming surface. The gap allows the light to have a certain irradiation gap, thereby increasing the range of light entering the arc-shaped light-incoming surface and improving the lighting effect.

[0032] At the same time, in this embodiment, the side of the second light-transmitting silicone strip away from the first light-transmitting silicone strip is a concave arc-shaped light-emitting surface 10. In actual application, the thickness of the middle part of the second light-transmitting silicone strip is greater than the thickness of the two sides. The light passing through the second light-transmitting silicone strip is then irradiated outward through the concave arc-shaped light-emitting surface, which can make the irradiated light converge to the middle part, improve the lighting effect, and also improve the uniformity and softness of the emitted light.

[0033] In actual application, the irradiation groove is an isosceles trapezoidal groove; the two edges of the arc-shaped light-incoming surface of the second light-transmitting silicone strip are respectively attached to the symmetrical inner walls of the isosceles trapezoidal groove. Through the above structure, the sealing of the connection can be ensured, thereby reducing light leakage, improving lighting efficiency, and being highly practical.

[0034] The utility model has positive effects: the structure of the utility model is reasonably arranged, and an irradiation groove is provided on the side of the first light-transmitting silicone strip, and is matched with an arched protrusion and an inclined convex strip, so that the light of the LED light source board is transmitted and refracted by the first light-transmitting silicone strip, and then gathered to the middle part of the arched protrusion, so that the light-emitting angle becomes a focusing state, and the focused light passes through the second light-transmitting silicone strip, and then refracted by the arc-shaped light-incoming surface and irradiated outward, so that the irradiated light can be made more uniform and soft, which solves the technical problem of glare of light and is beneficial to improving the irradiation effect, and it does not require a lens, so that the lamp beads on the LED light source board can be more within a certain length, which is beneficial to improving the lighting effect, and also beneficial to reducing costs, and has strong applicability and good practicality.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
