[0001] The utility model relates to the technical field of lighting, and more particularly to a light blocking and uniform light structure. Background Art
[0002] Existing LED light strips are primarily used in two ways: 1. The LED light strip is directly attached to the surface, or enclosed in a transparent plastic tube. When powered on, the LED light strip flashes to attract consumers' attention. However, this method produces glaring light, resulting in a poor consumer experience. Furthermore, the light diffuses, causing light pollution.
[0003] 2. Using a transparent or translucent plastic cavity to enclose the LED light strip, however, due to the spacing of the LED beads on the LED light strip, the light intensity is higher and brighter closer to the beads, while the light intensity is lower and dimmer farther away. This creates a lighting effect with alternating bright and dark intervals. When the lighting effect is set to the marquee lighting mode or the breathing light mode, the light is uneven and lacks a soft feeling. This method does not take into account the enclosed nature of the LED light strip, and the light often diverges, causing light pollution.
[0004] Therefore, how to reduce the light pollution caused by the use of light strips has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0025] In addition to the problems mentioned in the background technology, the exposed LED light strip also has the problem that the LED beads on the LED light strip may short-circuit and burn out when exposed to rain or dust.
[0026] Related explanation:
[0027] Marquee lighting mode: The lamp beads on an LED light strip change colors alternately in a certain color order. The lamp beads along the specified direction change in sequence with a delay. The color alternation order is consistent, which will produce a lighting effect of various colors on the light strip running along the specified direction.
[0028] Breathing light mode: All the lamp beads on an LED light strip change colors alternately in a certain color sequence at the same time, which will produce a lighting effect in which various colors on the light strip change at the same time, similar to the effect of gas strength when the human body breathes.
[0029] The core of the utility model is to disclose a light blocking and uniform light structure to reduce light pollution caused by the use of light strips.
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] like Figure 1 and Figure 3 As shown, an embodiment of the present utility model discloses a light blocking and uniform light structure, which includes a light strip 10 , a decorative member 20 , a light guide member 30 and a frame 40 .
[0032] The light strip 10 is provided with spaced-apart lamp beads that emit light when powered. The decorative member 20 and the frame 40 are both opaque, while the light guide 30 is transparent. The light strip 10 is positioned on one of the decorative member 20 and the light guide 30, which is positioned between the decorative member 20 and the frame 40. The portion of the light strip 10 not obscured by the decorative member 20 or the frame 40 forms an exit window, through which light is emitted.
[0033] Specifically, the light strip 10 is a flat strip, and the lamp beads are preferably arranged at even intervals. The lamp beads can change to various common light colors such as red, green, blue, and purple according to the control signal of the control circuit. The switching order and switching speed of various colors can be controlled according to needs.
[0034] The light-blocking and light-homogenizing structure disclosed in the embodiment of the present invention has a non-transparent structure. The light emitted by the light strip 10 can only be emitted through the light guide 30. The light guide 30 is arranged between the decorative part 20 and the rack 40. The part not blocked by the decorative part 20 and the rack 40 forms an exit window. The light emitted by the light strip 10 can only be emitted from the exit window, which reduces the occurrence of light pollution caused by the uncontrolled light emitted by the light strip 10.
[0035] It should be noted that the specific connection method of the decorative member 20, the light guide member 30 and the frame 40 can be a snap connection or they can be connected through a connecting member.
[0036] In some specific embodiments, Figure 4 As shown, the decorative part 20 is provided with a first boss 21 and a second boss 22, and a first groove 23 is formed between the first boss 21 and the second boss 22. The light strip 10 is provided in the first groove 23. The light strip 10 and the first boss 21 are preferably connected by bonding, for example, double-sided tape can be used to stick the light strip 10 to the first boss 21. Specifically, the shape of the first boss 21 and the second boss 22 can be a long strip, a circle, or a semicircle, and the specific shape is not specifically limited. The light strip 10 is provided in the first groove 23, which can reduce the direct light emitted by the light strip 10 from entering the human eye, and can improve the phenomenon of light glare in the prior art, so as to provide consumers with a better experience. The side of the decorative part 20 away from the light guide 30 is a decorative surface, and a specific decorative pattern can be set according to needs.
[0037] In order to further reduce the glare caused by the direct light from the light strip 10 entering the human eyes, based on the above embodiment, Figure 3As shown, a second groove 30 is provided on the light guide 30, and the first boss 21 and / or the second boss 22 on the decorative member 20 cooperate with the second groove 30. Part of the light emitted by the light strip 10 is blocked by the first boss 21 and the second boss 22 on the decorative member 20, and the part entering the light guide 30 is emitted from the exit window after at least one reflection.
[0038] In some specific embodiments, Figure 3 and Figure 4 As shown, the light strip 10 , the first groove 23 and the second groove 31 are all annular. Furthermore, the first boss 21 and the second boss 22 are both circular, and the second boss 22 matches the second groove 31 .
[0039] In some specific embodiments, Figure 3 and Figure 4 As shown, the frame 40 is provided with a receiving cavity 41 capable of accommodating the light guide 30. The light guide 30 is provided with a third boss 32. Specifically, the third boss 32 is annular. When the light guide 30 is installed on the frame 40, the third boss 32 is exposed on the frame 40, forming an exit window. The decorative member 20, the light guide 30 and the frame 40 form a closed structure, and the light strip 10 is located in the closed structure formed by the three. Figure 5 As shown, the light emitted by the lamp beads is blocked by the second boss 22, and the portion entering the light guide 30 is reflected at least once before being emitted from the exit window, thereby avoiding the glare caused by the light emitted by the light strip 10 directly hitting the human eye.
[0040] Compared with the prior art method of directly exposing the light strip 10, the light-blocking and uniform light structure disclosed in the embodiment of the utility model can reduce light pollution, and at the same time reduce the occurrence of lamp bead short circuit and burning caused by rain or dust, thereby extending the service life of the light strip 10.
[0041] During installation, install the light strip 10 in the first groove 21, then install the decorative part 20 on the light guide 30 so that the second boss 22 matches the second groove 22, and then install the light guide 30 on the bracket 40. The structure is simple and the installation is convenient.
[0042] In order to ensure the firmness of the connection between the decorative member 20, the light guide member 30 and the frame 40, the three are connected by fasteners. Specifically, the fasteners pass through the mounting holes on the frame 40 and the light guide member 30 and are threadedly engaged with the threaded holes on the decorative member 20. Specifically, the fasteners can be bolts, such as Figure 4 As shown, the decorative member 20 is provided with bolt columns that match the bolts, and the bolt columns are arranged at intervals along the circumference of the decorative member 20, and the light guide 30 and the frame 40 are provided with mounting holes that correspond one to one with the bolt columns.
[0043] In order to ensure the normal lighting of the light strip 10, the light strip 10 is connected to the power supply through a cable. The positive and negative electrodes and the control circuit cables are welded at the head and tail ends of the light strip 10 respectively. Cable ports for the cables to pass through are opened on the first groove 23, the second groove 31 and the frame 40. Figure 4 As shown, the cable openings on the first groove 23 and the second groove 31 are preferably arranged at the bottom, and the cable opening on the rack 40 is preferably arranged at the center of the rack 40, as shown in FIG. Figure 2 As shown, after the cable passes through the rack 40, a fixed foam glue is used to fill the cable opening to limit the light emitted by the light strip 10 to the closed space formed by the decorative member 20, the light guide member 30 and the rack 40, thereby reducing light pollution.
[0044] In order to fully diffuse the light emitted by the light strip 10 and present a uniform, natural and soft effect in the exit window, diffusion powder is added to the light guide 30 during the manufacturing process, so that the light emitted by the light strip 10 is fully diffused when it is reflected multiple times in the light guide 30. The addition ratio of the diffusion powder is preferably 1%-3%. The specific addition ratio can be determined according to the structure of the light guide 30 and the intensity of the light emitted by the lamp beads. The fewer times the light is refracted in the light guide 30, the stronger the intensity of the emitted light, and the closer the ratio value is to the upper limit of the preferred value. The light-blocking and uniform light structure disclosed in the new embodiment of the present invention has a natural and soft transition of light in the marquee light mode and the breathing light light mode, presenting a different aesthetic feeling, which can enhance the consumer experience.
[0045] In the light-blocking and light-homogenizing structure disclosed in the embodiment of the present invention, the shape of the light guide 30 can be circular, elliptical, or polygonal (e.g., triangular, rectangular, etc.), and the shape of the decorative member 20 is preferably the same as that of the light guide 30, with the first boss 21 and the second boss 22 being arranged concentrically with the decorative member 20. It will be appreciated by those skilled in the art that the shapes of the decorative member 20 and the light guide 30 can also be other shapes, such as square or triangular, and can be specifically determined according to actual needs.
[0046] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same and similar parts between the various embodiments can be referenced to each other.
