Description

Technical Field

[0001] The present application relates to the field of light guide plates for LED lamps, and in particular to a light guide strip structure. Background Art

[0002] The light guide plate is made of acrylic sheet, which has a high refractive index and does not absorb light. The light guide points are printed on the bottom of the optical-grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. When the light hits each light guide point, the reflected light will diffuse to various angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can emit light evenly.

[0003] LED lamps and light guide plates can be installed in existing electrical boxes, so that the LED lamps can play a decorative effect and improve the aesthetics of the electrical box. A PCB board is fixed in the electrical box, and multiple LED lamps are installed on the PCB board, each of which can emit light of different colors. The light guide plate is inserted into the electrical box and blocks the opening of the electrical box. By arranging a light guide plate in the electrical box, multiple LED lamps can illuminate the light guide plate respectively and make the light guide plate on the surface of the electrical box show different colors. By controlling multiple LED lamps to emit light at the same time, the user can make the surface of the electrical box produce multiple colors to improve the aesthetics.

[0004] The above-mentioned related technical solutions have the following defects: when multiple LED lamps are illuminated at the same time, due to the presence of multiple light sources in the electrical box, multiple LED lamps illuminate the light guide plate at the same time, which in turn causes a color cross-talk problem, causing the light guide plate to display a color different from the color of the LED lamp. Utility Model Content

[0005] In order to reduce the problem of color crosstalk in an electrical box, the present application provides a light guide strip structure.

[0006] The present application provides a light guide strip structure that adopts the following technical solution:

[0007] A light guide strip structure comprises an electrical box, a PCB board, a plurality of LED lamps and a light guide assembly, wherein the electrical box comprises an end cover and a side wall, wherein the side wall is a cylindrical structure, the end cover is fixed to one side of the side wall, the PCB board is arranged in the electrical box, the plurality of LED lamps are connected to the PCB board, the light guide assembly comprises a cover plate and a plurality of light guide columns, one end of the light guide column is fixed to the cover plate, and the other end abuts against the LED lamp, and the cover plate cover is arranged on the opening of the electrical box.

By inserting a light guide component in the electrical box, multiple light guide columns on the cover plate are respectively abutted against LED lamps of different colors. When the LED lamp emits light, each LED lamp transmits light through a light guide column, so that different positions on the cover plate can emit light through different light guide columns, so that the appearance of the electrical box shows different colors. When multiple LED lamps emit light at the same time, the light of the LED lamp is transmitted through the light guide column at the position, and the light emitted by adjacent LED lamps is difficult to irradiate and transmit on the light guide columns at other positions, thereby reducing the problem of cross-lighting in the electrical box, so that the color on each light guide column corresponds to the color of the LED lamp at the position, so that the color of the appearance of the electrical box can be set according to the light emission color of the LED lamp.

[0010] By adopting the above technical solution, a cover shell is set on the cover plate, so that the side wall of the electrical box is set to be transparent. When the LED lamp is lit, the light is transmitted through the light guide component, so that the cover shell can emit light, thereby increasing the area on the outer surface of the electrical box that can emit light, and further improving the aesthetics of the electrical box.

[0011] Optionally, a light-shielding sleeve is provided at the end of the light-guiding column. The light-shielding sleeve is made of rubber material and has an annular structure. When the light-guiding column abuts against the LED lamp, the light-shielding sleeve is arranged outside the LED lamp.

[0012] By adopting the above technical solution, a light-shielding sleeve is provided at the end of the light-guiding column, and the light-shielding sleeve is elastic. When the light-guiding column abuts against the LED lamp, the light-shielding sleeve is provided outside the LED lamp, thereby reducing the probability of light emitted by the LED lamp irradiating other light-guiding columns, and further reducing the probability of multiple LED lamps in the electrical box being strung together. The light-shielding cover abuts against the PCB board, which can reduce the probability of the light-shielding cover scratching the PCB board and causing malfunctions.

[0013] Optionally, a mounting groove is provided at the center of the end surface of the light guide column, and when the light guide column is in contact with the LED lamp, the LED lamp is located in the mounting groove.

[0014] By adopting the above technical solution, by providing a mounting groove on the light guide column, the LED lamp can be arranged in the mounting groove, thereby reducing the probability of the light of the LED lamp irradiating on other light guide columns when emitting light.

[0015] Optionally, the light guide components are provided in plurality, each light guide component comprises a cover plate, a light guide column and a plurality of cover shells, and the plurality of light guide components are spliced ​​with each other and provided on the electrical box.

[0016] By adopting the above technical solution, by splicing multiple light guide components together and inserting them into the electrical box, the user can adjust the number of light guide components according to the number of LED lights set in the electrical box, thereby facilitating the user to assemble the electrical box.

[0019] Optionally, the light blocking member is made of rubber material.

[0020] By adopting the above technical solution and using rubber to make the light blocking member, when multiple light guide components are inserted into the electrical box, the light blocking member can be deformed and block the gaps between the light guide components, thereby improving the stability of the connection between the light guide components and the electrical box.

[0021] Optionally, a plurality of connecting parts are provided on the electrical box.

[0022] By adopting the above technical solution and arranging a connector on the electrical box, a user can fix the electrical box by bolts, thereby making it convenient for the user to install and set the electrical box.

[0023] In summary, the beneficial technical effects of this application are:

[0024] 1. By arranging a PCB board in the electrical box, the PCB board can supply power to the LED lamp and control the LED lamps of different colors to emit light. By inserting a light guide assembly into the electrical box, a plurality of light guide posts on the cover plate are respectively abutted against the LED lamps of different colors. When the LED lamp emits light, each LED lamp transmits light through a light guide post, so that different positions on the cover plate can emit light through different light guide posts, so that the appearance of the electrical box shows different colors. When multiple LED lamps emit light at the same time, the light of the LED lamp is transmitted through the light guide post at the position, and the light emitted by the adjacent LED lamp is difficult to irradiate and transmit on the light guide posts at other positions, so as to reduce the problem of light crosstalk in the electrical box, so that the color on each light guide post corresponds to the color of the LED lamp at the position, so that the color of the electrical box appearance can be set according to the light emission color of the LED lamp;

[0025] 2. By setting a cover on the cover plate, the side wall of the electrical box is set to be transparent. When the LED lamp is lit, the light is transmitted through the light guide component, so that the cover can emit light, thereby increasing the area on the outer surface of the electrical box that can emit light, further improving the aesthetics of the electrical box;

[0026] 3. By setting a shading sleeve at the end of the light guide column, the shading sleeve is elastic. When the light guide column abuts against the LED lamp, the shading sleeve is arranged outside the LED lamp, thereby reducing the probability of light emitted by the LED lamp irradiating other light guide columns, and further reducing the probability of multiple LED lamps in the electrical box being strung together. The shading cover abuts against the PCB board, which can reduce the probability of the shading cover scratching the PCB board and causing malfunctions. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] The present application embodiment discloses a light guide strip structure, referring to Figure 1 , Figure 2 and Figure 3, including an electrical box 1, a PCB board 2, an LED lamp 3 and a light guide component 4. The electrical box 1 includes an end cover 11 and a side wall 12. The side wall 12 is a cylindrical structure. The side wall 12 is fixed around the end cover 11, so that the electrical box 1 forms a box body structure with an opening. The side wall 12 is connected to a plurality of connectors 121. The connectors 121 are provided with through holes. The user can set bolts in the through holes, so that the electrical box 1 can be installed in different positions. The PCB board 2 is installed in the electrical box 1. A plurality of LED lamps 3 are installed on the PCB board 2. Each LED lamp 3 can emit light of different colors. The light guide component 4 is covered on the electrical box 1. The electrical box 1 is made of transparent material. When the LED lamp 3 is lit, the electrical box 1 can display an appearance of different colors, thereby achieving an aesthetic effect. The light guide component 4 is made of acrylic plate, and light can be refracted in the light guide component 4. When the LED lamp 3 is lit, the light guide component 4 appears to be luminous. The electrical box 1 is made of transparent material, so that the electrical box 1 can show the luminous state of the light guide component 4, thereby achieving an aesthetic effect.

[0037] Reference Figure 4 The light guide assembly 4 includes a cover plate 41 and a plurality of light guide columns 42. The cover plate 41 is used to cover the opening of the electrical box 1 and bonded to the electrical box 1. The cover plate 41 protects the PCB board 2 and the LED lamp 3, and can reduce the probability of water entering the electrical box 1. The light guide column 42 is fixed on the cover plate 41. The position of the light guide column 42 corresponds to the position of the LED lamp 3. The light guide column 42 is a cylindrical structure, and the light guide column 42 is vertically arranged with the cover plate 41. When the cover plate 41 is covered on the electrical box 1, a plurality of light guide columns 42 are inserted into the electrical box 1. Each light guide column 42 abuts against an LED lamp 3. When the LED lamp is lit, the different colors of light emitted by the LED lamp 3 are transmitted to the cover plate 41 through the light guide column 42, thereby achieving a beautiful effect. When the LED lamp 3 is lit, the light guide column 42 has the effect of blocking the light, which can reduce the scattering of light in the electrical box 1, so that the color displayed on each light guide column 42 is close to the color of the LED lamp at its position, which can reduce the degree of cross-talk when multiple LEDs in the electrical box 1 are lit at the same time, and make the light displayed on the cover plate 41 close to the color emitted by the LED lamp 3.

[0038] Reference Figure 6, a cover shell 43 is arranged on the cover plate 41, and the cover shell 43 is a cylindrical structure, and the shape of the cover shell 43 corresponds to the side wall 12, and the cover shell 43 is fixed on the cover plate 41, and a plurality of light guide columns 42 are arranged in the cover shell 43. When the cover plate 41 is covered on the electrical box 1, the cover shell 43 is inserted into the electrical box 1 and fits with the side wall 12. The cover plate 41, the light guide column 42 and the cover shell 43 are all made of light-guiding materials. When the plurality of LED lamps 3 emit light, each LED lamp 3 transmits light through the light guide column 42 at the position, so that different positions of the appearance of the electrical box 1 present different colors, and the color on each light guide column 42 corresponds to the light color of the LED lamp 3 at the position, which can reduce the probability that the light emitted by the LED lamp 3 at other positions is irradiated on the same light guide column 42 and transmitted, thereby making the appearance color of the electrical box 1 correspond to the position and color of the LED lamp, so that the appearance of the electrical box 1 can present different colors.

[0039] Reference Figure 4 , a light shielding sleeve 421 is provided at the end of the light guide column 42. The light shielding sleeve 421 is made of opaque rubber and has an annular structure. When the light guide column 42 abuts against the LED lamp 3, the light shielding sleeve 421 is sleeved outside the LED lamp 3 and abuts against the PCB board 2. The light shielding sleeve 421 is made of elastic rubber. When the light guide column 42 is installed on the LED lamp 3, the light shielding sleeve 421 automatically deforms, which can reduce the probability of scratching the PCB board 2. When the LED lamp 3 is lit, the light emitted by the LED lamp 3 can only be transmitted through one light guide column 42. The color on each light guide column 42 is the same as the color of the LED lamp 3 at the location, which can reduce the problem of cross-light when multiple LED lamps 3 in the electrical box 1 are lit at the same time.

[0040] Reference Figure 5 In other embodiments, a mounting groove 422 is provided at the end of the light guide column 42, and the mounting groove 422 is provided at the center of the end surface of the light guide column 42. When the light guide column 42 is installed in the electrical box 1, the LED lamp 3 is arranged in the mounting groove 422. When the LED lamp 3 emits light, the probability of the light of the LED lamp 3 irradiating on other light guide columns 42 can be reduced, and the problem of light crosstalk in the electrical box 1 can be further reduced.

[0041] Reference Figure 7 In other embodiments, the light guide components 4 are spliced ​​together, and each light guide component 4 includes a cover plate 41, a light guide column 42, and a plurality of cover shells 43, and the light guide components 4 are integrally formed. Users form light guide components 4 of different shapes by splicing, so that the cover plates 41 on each light guide component 4 can be spliced ​​together and covered on the opening of the electrical box 1, thereby facilitating users to install light guide components 4 in electrical boxes 1 with different numbers of LED lamps 3.

[0042] Reference Figure 7A light blocking member 44 is provided between two adjacent light guide components 4. The light blocking member 44 is made of an opaque rubber material and can be provided as a frame structure or a flat plate structure. The two light guide components 4 mutually clamp the light blocking member 44. When the light guide component 4 is installed in the electrical box 1, the light blocking member 44 can be provided between two adjacent LED lamps 3 to further reduce the probability of light crosstalk in the electrical box 1. The light blocking member 44 is elastic. When the light guide component 4 is provided in the electrical box 1, the light blocking member 44 can fill the gap between the light guide components 4.

[0043] The implementation principle of the embodiment of the present application is as follows: by setting a PCB board 2 in the electrical box 1, and setting multiple LED lamps 3 on the PCB board 2, the LED lamps 3 can emit light of different colors, so that the light guide component 4 can refract the light emitted by the LED lamp 3 and have a decorative effect on the electrical box 1; by setting multiple light guide columns 42 on the cover plate 41, each light guide column 42 is set corresponding to an LED lamp 3, when the LED lamp 3 is lit, each LED lamp 3 illuminates a light guide column 42, so that the light color on each light guide column 42 is the same as the color of the LED lamp 3 at its position, thereby reducing the probability of the LED lamp 3 from shining in the electrical box 1, so that the appearance of the electrical box 1 can be closer to the light color of the LED lamp 3.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
