Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a side-emitting silicone light strip. Background Technology

[0002] Most silicone LED strips typically emit light from the front. Due to the structural limitations of silicone LED strips, the entire strip can only bend along the front or back, not from the side, which restricts its application. For example, if you want to provide "wall washing" lighting for a wall or cylinder with a large curved structure, the front of the silicone LED strip needs to be positioned horizontally (ideally horizontally) so that the light emitted from the front can illuminate the wall and create a wall washing effect. This requires the side of the silicone LED strip to bend to match the curved wall, which is difficult to achieve with conventional silicone LED strips. Furthermore, silicone LED strips often have lenses in front of the light source, so when the light is emitted from the front of the strip, some of the light will directly enter the eyes, causing glare. Utility Model Content

[0003] The purpose of this utility model is to address the problem that existing silicone light strips are mostly front-emitting, can be bent from the front but are difficult to bend from the side, and cannot adapt to the needs of wall washing lighting on curved walls or cylinders. At the same time, some of the light emitted from the front will directly enter the eyes, causing glare. This utility model provides a side-emitting silicone light strip.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A side-emitting silicone light strip includes a light-shielding gel and a light-transmitting gel. The light-shielding gel has a U-shaped cross-section, and a circuit board is disposed on one inner sidewall of the light-shielding gel. An LED light source is disposed on the circuit board. The light-transmitting gel is connected to the light-shielding gel, with a portion of the light-transmitting gel extending into the light-shielding gel and another portion sealing the opening of the light-shielding gel. Light emitted by the LED light source is emitted through the light-transmitting gel, and the light-transmitting gel is configured to guide all light rays to the same side of the normal.

[0006] The side-emitting silicone light strip of this invention, based on the arrangement of the circuit board within the light-shielding colloid, allows the light strip to bend only along its front side. However, since the light-emitting surface is located on the side of the light strip, bending it allows the emitted light to match the curved wall surface, forming wall-washing lighting. Simultaneously, the light-transmitting colloid is configured to guide all light rays to the same side of the normal, meaning the emitted light from the light strip has a polarization angle, causing the light to be completely deflected to one side and not directly enter the human eye, thus effectively avoiding glare. This light strip has a simple structure, is easy to use, and has good performance.

[0007] As a preferred technical solution of this utility model, an installation groove is provided on one inner side wall of the light-shielding colloid, and the circuit board is disposed in the installation groove.

[0008] As a further preferred technical solution of this utility model, the mounting groove is a T-shaped groove, the circuit board is snapped into the T-shaped groove, and the LED light source is located at the outlet of the T-shaped groove.

[0009] As a preferred technical solution of this utility model, the light-transmitting colloid includes a first incident surface, a first reflecting surface, a first refractive surface, a second refractive surface, and an exiting surface; part of the light emitted by the LED light source enters the light-transmitting colloid through the first incident surface, passes through the first reflecting surface and the first refractive surface in sequence and exits the light-transmitting colloid, then enters the light-transmitting colloid through the second refractive surface, and finally exits through the exiting surface.

[0010] As a preferred technical solution of this utility model, the light-transmitting colloid includes a first incident surface, a third refractive surface, a second refractive surface, and an exit surface; part of the light emitted by the LED light source enters the light-transmitting colloid through the first incident surface, exits the light-transmitting colloid through the third refractive surface, then enters the light-transmitting colloid through the second refractive surface, and finally exits through the exit surface.

[0011] As a preferred technical solution of this utility model, the light-transmitting colloid includes a second incident surface, a second reflecting surface, a first reflecting surface, a first refractive surface, a second refractive surface, and an exiting surface; part of the light emitted by the LED light source enters the light-transmitting colloid through the second incident surface, passes through the second reflecting surface, the first reflecting surface, and the first refractive surface in sequence and exits the light-transmitting colloid, then enters the light-transmitting colloid through the second refractive surface, and finally exits through the exiting surface.

[0012] As a preferred technical solution of this utility model, the light-transmitting colloid is a 7-shaped component, one side of the 7-shaped component closes the opening of the light-shielding colloid, and the other side extends into the light-shielding colloid and is close to the circuit board.

[0013] As a further preferred technical solution of this utility model, the bottom of the 7-shaped component abuts against the inner bottom of the light-shielding colloid.

[0014] As a further preferred technical solution of this utility model, a first cavity is provided between the 7-shaped component and the LED light source; a second cavity is provided between the 7-shaped component and the inner bottom of the light-shielding colloid, the second cavity being located below the first cavity; a third cavity is provided between the 7-shaped component and the light-shielding colloid, the third cavity being disposed opposite to the first cavity.

[0015] As a further preferred technical solution of this utility model, the light-transmitting colloid wall corresponding to the first cavity is provided with a first incident surface and a second incident surface; the light-transmitting colloid wall corresponding to the second cavity is provided with a second reflective surface; the light-transmitting colloid wall corresponding to the third cavity is provided with a second refractive surface, a third refractive surface and at least one serrated portion, one side of the serrated portion being the first reflective surface and the other side being the first refractive surface.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] The side-emitting silicone light strip of this utility model, based on the arrangement of the circuit board within the light-shielding colloid, allows the light strip to bend only along its front side. However, since the light-emitting surface is located on the side of the light strip, bending it allows the emitted light to match the curved wall surface, forming wall-washing lighting. Simultaneously, the light-transmitting colloid is configured to guide all light rays to the same side of the normal, meaning the emitted light from the light strip has a polarization angle, causing the light to be completely deflected to one side and not directly enter the human eye, thus effectively avoiding glare. This light strip has a simple structure, is easy to use, and has good performance. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0029] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0031] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0032] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0033] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0034] In related technologies, most silicone LED strips typically emit light from the front. Due to the structural limitations of silicone LED strips, the entire strip can only be bent along the front or back, and cannot be bent from the side (please refer to...). Figure 1 The light strip contains a circuit board 3. Typically, the light strip emits light from the front, and the circuit board 3 is vertically positioned. Bending the light strip from the front requires overcoming the bending stiffness of the circuit board 3 along its thickness. Bending the light strip from the side requires overcoming the bending stiffness of the circuit board 3 along its width. Since the width of the circuit board 3 is much greater than its thickness, it can hardly bend along its width (i.e., the light strip cannot bend from the side, only from the front). This limits its application scenarios. For example, if you want to provide "wall washing lighting" for a wall or cylinder with a large curved structure, the front of the silicone light strip needs to be horizontally positioned (preferably on a horizontal plane) so that the light emitted from the front can illuminate the wall and create a wall washing effect. This requires the side of the silicone light strip to bend to accommodate the curved wall, which is difficult to achieve with conventional silicone light strips. Furthermore, a lens is placed in front of the light source of the silicone light strip. When light is emitted from the front of the light strip, some of the light will directly enter the eyes, causing glare. Therefore, the technical solution of this application was developed. The following describes the solution in conjunction with... Figures 1 to 4 To elaborate.

[0035] Example 1

[0036] like Figures 1 to 4 As shown, the side-emitting silicone light strip of this utility model includes a light-shielding colloid 1 and a light-transmitting colloid 2. The specific materials and molding methods of the light-shielding colloid 1 and the light-transmitting colloid 2 have been extensively documented in the prior art and will not be repeated here.

[0037] like Figure 1 and Figure 2 As shown, the light-shielding colloid 1 is a long strip with a U-shaped cross-section in the width direction. A circuit board 3 is provided on one inner side wall of the light-shielding colloid 1, and a number of LED light sources 4 are arranged at equal intervals on the circuit board 3.

[0038] In some optional embodiments, a mounting groove is provided on one inner sidewall of the light-shielding colloid 1, and the circuit board 3 is disposed in the mounting groove, for example, by snap-fit ​​connection or adhesive bonding; specifically optional, such as Figure 2 As shown, the mounting groove is a T-shaped groove, the circuit board 3 is snapped into the T-shaped groove, and the LED light source 4 is located at the outlet of the T-shaped groove.

[0039] like Figure 1 and Figure 2 As shown, the light-transmitting colloid 2 is a long strip with a cross-section in the width direction that is shaped like the number 7. The light-transmitting colloid 2 is connected to the light-shielding colloid 1 (generally by adhesive). A part of the light-transmitting colloid 2 extends into the light-shielding colloid 1, and the other part seals the opening of the light-shielding colloid 1.

[0040] like Figure 3 and Figure 4 As shown, the light emitted by the LED light source 4 is emitted through the light-transmitting colloid 2, which is configured to guide all light rays to the same side of the normal.

[0041] In some alternative implementations, such as Figure 2 As shown, the light-transmitting colloid 2 is a 7-shaped component. One side of the 7-shaped component closes the opening of the light-shielding colloid 1, and the other side extends into the light-shielding colloid 1 and is close to the circuit board 3. The bottom of the 7-shaped component abuts against the inner bottom of the light-shielding colloid 1. There is a first cavity between the 7-shaped component and the LED light source 4. There is a second cavity between the 7-shaped component and the inner bottom of the light-shielding colloid 1. The second cavity is located below the first cavity. There is a third cavity between the 7-shaped component and the light-shielding colloid 1. The third cavity is arranged opposite to the first cavity.

[0042] In some alternative implementations, such as Figure 2 As shown, the wall of the light-transmitting colloid 2 corresponding to the first cavity is provided with a first incident surface 21 and a second incident surface 22. The wall of the light-transmitting colloid 2 corresponding to the second cavity is provided with a second reflective surface 23. The wall of the light-transmitting colloid 2 corresponding to the third cavity is provided with a second refractive surface 27, a third refractive surface 26 and at least one serrated portion. One side of the serrated portion is a first reflective surface 24 and the other side is a first refractive surface 25. The outer surface of the light-transmitting colloid 2 is an exit surface 28. Among them, the first incident surface 21, the second incident surface 22, the second reflective surface 23, the first reflective surface 24, the first refractive surface 25, the third refractive surface 26, the second refractive surface 27 and the exit surface 28 are all free-form surfaces.

[0043] like Figure 3As shown, some of the light emitted by the LED light source 4 enters the light-transmitting colloid 2 through the first incident surface 21, passes through the first reflective surface 24 and the first refractive surface 25 in sequence and exits the light-transmitting colloid 2, then enters the light-transmitting colloid 2 through the second refractive surface 27, and finally exits through the exit surface 28.

[0044] like Figure 3 As shown, some of the light emitted by the LED light source 4 enters the light-transmitting colloid 2 through the first incident surface 21, exits the light-transmitting colloid 2 through the third refractive surface 26, then enters the light-transmitting colloid 2 through the second refractive surface 27, and finally exits through the exit surface 28.

[0045] like Figure 3 As shown, some of the light emitted by the LED light source 4 enters the light-transmitting colloid 2 through the second incident surface 22, passes through the second reflecting surface 23, the first reflecting surface 24, and the first refractive surface 25 in sequence, exits the light-transmitting colloid 2, then enters the light-transmitting colloid 2 through the second refractive surface 27, and finally exits through the exit surface 28.

[0046] The side-emitting silicone light strip described in this embodiment, based on the arrangement of the circuit board 3 within the light-shielding colloid 1, allows the light strip to bend only along its front side. However, because the light-emitting surface is located on the side of the light strip, bending it allows the emitted light to match the curved wall surface, forming wall-washing lighting. Simultaneously, the light-transmitting colloid 2 is configured to guide all light rays to the same side of the normal, meaning the emitted light from the light strip has a polarization angle, such as... Figure 4 As shown, the light is completely deflected to one side and does not directly enter the human eye, thus effectively avoiding glare; the light strip has a simple structure, is easy to use, and has good effect.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
