[0001] The utility model relates to the technical field of LED light strips, and particularly relates to a silica gel light strip for long-distance power supply. Background Art

[0002] The LED silica gel light strip is a kind of flexible light source board formed by welding patch LED lamp beads on a flexible lamp board, and the flexible light source board is extruded and formed together with silica gel through a special extrusion die. Since the light source board is wrapped in silica gel, it has the characteristics of good waterproof performance, easy bending, long service life, etc., and is suitable for various indoor and outdoor decorative lighting to enhance the atmosphere of the environment.

[0003] The length of the LED silica gel light strip is very long, and there is a voltage difference between the head and the tail of the light strip, resulting in different brightness at the head and the tail, and there are obvious differences in the lighting effect. Therefore, in order to meet people's visual effects, only short-distance power supply can be adopted. Multiple short-distance power supply silica gel light strips are spliced end to end to form a silica gel light strip with a longer length. This will require more driving power supplies and wires to supply power to the silica gel light strip, with a large amount of construction work and high installation costs.

[0004] It can be seen that the existing technology still needs to be improved. Summary of the Utility Model

Detailed implementation manners

[0023] The present utility model provides a silicone light strip for long-distance power supply. To make the purpose, technical solution and effects of the present utility model clearer and more definite, the following further details the present utility model with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Please refer to Figures 1 to 4 As shown, the present utility model provides a silicone light strip for long-distance power supply. The silicone light strip is an indeterminate-length light-emitting body. The silicone light strip can be fixed on the wall through an aluminum groove, can be fixed in the installation groove by gluing, or can be fixed on the wall through a light strip keel, so that the silicone light strip can be bent and installed arbitrarily, thereby playing a role in decorative lighting. The silicone light strip includes a silicone housing 1, a first transparent silicone strip 2 covering the silicone housing 1, a light source board 3 installed in the silicone housing 1, an anti-breaking piece 4 provided at the bottom of the light source board 3, and plugs 5 for closing both ends of the silicone housing 1. The light source board 3 includes a flexible light board 31 and a plurality of lamp beads 32 welded on the flexible light board 31. A plurality of groups of pads 33 are provided on the flexible light board 31. The anti-breaking piece 4 includes a flexible installation strip 41 and a plurality of conductive wires 42 adhered to the flexible installation strip 41. Multiple groups of pads 33 are correspondingly abutted against the conductive wires 42 to achieve long-distance power supply.

[0025] In actual use, the pads 33 on the entire flexible light board 31 are respectively in contact with the corresponding conductive wires 42, and the conductive wires 42 are used to achieve long-distance power supply. The conductive wires 42 play a role in shunting the lamp beads 32 welded on the flexible light board 31, so that the current flowing through the lamp beads 32 is as close as possible, ensuring that there is no voltage difference at the head and tail ends of the flexible light board 31, and realizing the function of consistent lighting effects at the head and tail ends of the silicone light strip. In addition, under the action of the conductive wires 42, the structural strength of the silicone light strip can also be improved, avoiding the situation that the light source board 3 breaks or the lamp beads 32 have poor contact due to excessive stretching of the silicone light strip.

[0026] Preferably, the conductive wire 42 is made of red copper, which has good electrical conductivity and thermal conductivity, and can achieve long-distance power transmission to the light source board 3 and heat dissipation function.

[0027] In a preferred embodiment, refer to Figure 2 , 3 , a first arc surface 21 is provided on the outer side of the first transparent silicone strip 2, and a second arc surface 11 that fits the first arc surface 21 is provided on the inner side of the silicone housing 1. Through the above settings, the stability of the combination of the first transparent silicone strip 2 and the silicone housing 1 can be improved; and the outer side of the first transparent silicone strip 2 is flush with the outer side of the silicone housing 1 to increase the light-emitting range of the silicone light strip, so that light is refracted out from the top and the edges near the top, avoiding the formation of dark areas.

[0028] Among them, the first transparent silicone strip 2 is made of transparent silicone material or silicone added with a diffusing agent to achieve the effect of light transmission; the silicone housing 1 is made of light-blocking silicone to block the places that do not need to emit light.

[0029] In a preferred embodiment, refer to Figure 2 , 3 , a first mounting groove 12 is formed on the side wall of the silicone housing 1, and the light source board 3 and the anti-breaking piece 4 are both mounted on the first mounting groove 12 to improve the mounting stability of the light source board 3 and the anti-breaking piece 4, and at the same time ensure the contact stability between the conductive wire 42 and the pad 33.

[0030] In a preferred embodiment, refer to Figure 3 , a second mounting groove 411 matching the conductive wire 42 is formed on the flexible mounting strip 41. The second mounting groove 411 can increase the contact area between the conductive wire 42 and the flexible mounting strip 41 to improve the mounting stability of the conductive wire 42. During production, the conductive wire 42 is first fixed on the flexible mounting strip 41 by gluing to make the anti-breaking piece 4, and then the anti-breaking piece 4 and the light source board 3 are extruded together with the silicone housing 1 and the first transparent silicone strip 2 through a special extrusion die. During the extrusion process, the contact stability between the conductive wire 42 and the pad 33 is ensured by the limitation of the first mounting groove 12.

[0031] Preferably, the height of the second mounting groove 411 on the side close to the silicone housing 1 is higher than that on the other side to prevent a small amount of silicone from seeping into the gap between the flexible light board 31 and the flexible mounting strip 41, increasing the distance between the pad 33 and the conductive wire 42 and causing unstable contact between the conductive wire 42 and the pad 33.

[0032] In a preferred embodiment, refer to Figure 3, each group of the pads 33 includes a positive electrode solder joint 331 and a negative electrode solder joint 332. One conductive wire 42 abuts against all the positive electrode solder joints 331, and the other conductive wire 42 abuts against all the negative electrode solder joints 332; and the width of the conductive wire 42 is the same as that of the positive electrode solder joint 331 and the negative electrode solder joint 332 to ensure that the conductive wire 42 contacts the positive electrode solder joint 331 and the negative electrode solder joint 332 and the power is supplied normally.

[0033] Optionally, the cross-section of the conductive wire 42 is circular or rectangular. In practical applications, the size of the cross-section of the conductive wire 42 is related to the length of the silicone light strip to be loaded. The longer the length of the silicone light strip, the greater the power, and the larger the corresponding cross-section of the conductive wire 42.

[0034] In a preferred embodiment, referring to Figure 2 , a first light-dimming part 22 is arranged in the first transparent silicone strip 2. The first light-dimming part 22 is an arc surface, and the light emitted by the lamp beads 32 is adjusted by the first light-dimming part 22 for the first time in terms of the light-emitting angle to achieve the purpose of light projection.

[0035] In a preferred embodiment, referring to Figure 2 、 4 , a visible window 6 is arranged at the bottom of the silicone housing 1. The visible window 6 is made of transparent silicone material or silicone added with a diffusing agent; meanwhile, the flexible mounting strip 41 is made of transparent PC / PVC material. Through the visible window 6, it is convenient to check the position of the pads 33 on the light source board 3. Since the silicone light strip is processed by an integral extrusion molding method and its length is infinite, in actual production, an enterprise can cut the silicone light strip according to the actual length requirements of customers, and the cutting position should be the position of the pads 33 on the light source board 3. After cutting, the power cord is welded to the pads 33 at the end of the light source board 3, so as to realize the normal power supply of the silicone light strip, and finally the two ends of the silicone light strip are sealed by installing plugs 5. Specifically, the plugs 5 are made of silicone material and are adhered to the silicone light strip through a mold to play a waterproof role.

[0036] It should be understood that the power cord includes a positive electrode wire, a negative electrode wire and multiple signal wires to control the light-emitting color and light-emitting frequency of the lamp beads 32, so as to achieve different light-emitting effects. Among them, the positive electrode wire is welded and fixed to the positive electrode solder joint 331 at the end of the light source board 3, and the negative electrode wire is welded and fixed to the negative electrode solder joint 332 at the end of the light source board 3. Through the conductive function of the conductive wire 42, the function of long-distance power supply is realized, so that the current flowing through each lamp bead 32 is close to each other, that is, there is no voltage difference between the lamp beads 32 at the head and tail ends of the light source board 3. When the length of the silicone light strip is extremely long, the light-emitting effects at its head and tail ends are consistent, which can reduce the number of driving power supplies and wires, reduce the construction workload at the same time, speed up the construction speed, and greatly save the material cost and labor cost.

[0037] In a preferred embodiment, referring to Figure 2 and 4 , a plurality of grooves 13 extending along the length direction are formed at the bottom of the silica gel housing 1. Through the plurality of grooves 13, the surface area of the bottom of the silica gel housing 1 is increased. When the position of the silica gel housing 1 is fixed by gluing, the installation stability of the silica gel light strip can be improved.

[0038] In a preferred embodiment, referring to Figure 4 , it further includes a second transparent silica gel strip 7 detachably mounted on the first transparent silica gel strip 2. A refraction part 71 is provided on the second transparent silica gel strip 7, and both the upper surface and the lower surface of the refraction part 71 have textures. The light refracted from the first transparent silica gel strip 2 is subjected to secondary light output adjustment through the second transparent silica gel strip 7. Since both the upper surface and the lower surface of the refraction part 71 have textures, the light is diffused, so that the refracted light and shadow have textures, thereby presenting different light output effects. Moreover, when the light output effect after passing through the refraction part 71 is combined with the light emission frequency of the control lamp beads 32, the silica gel light strip can present a dynamic light and shadow light output effect, thereby improving the atmosphere in the lighting environment.

[0039] Wherein, the texture on the refraction part 71 can be formed by pressing with a patterned pressing roller.

[0040] Furthermore, two supporting feet 72 are provided on the second transparent silica gel strip 7, clamping grooves 23 are provided on both sides of the first transparent silica gel strip 2, and convex strips 73 inserted into the clamping grooves 23 are provided on the supporting feet 72. During installation, the second transparent silica gel strip 7 is sleeved on the first transparent silica gel strip 2, and the two convex strips 73 are correspondingly inserted into the two clamping grooves 23 to realize the installation of the second transparent silica gel strip 7.

[0041] Preferably, referring to Figure 4 , the supporting feet 72 cover the side wall of the first transparent silica gel strip 2. The refraction part 71 is made of transparent silica gel material or silica gel added with a diffusing agent, and the supporting feet 72 are made of light-blocking silica gel, so that the light only diverges from the refraction part 71.

[0042] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concepts of the present invention, and all such changes or substitutions should fall within the protection scope of the claims attached to the present invention.
