[0005] As an improvement to the above technical solution, a plug-in assembly is provided on each opposite side of the protective shell. The plug-in assembly includes a plug cylinder and a baffle. The plug cylinder is integrally disposed on the outside of the through hole of the protective shell, and the baffle is disposed on the inside of the protective shell. The baffle is located at the edge of the through hole of the protective shell. A limiting groove is provided on the side wall of the plug cylinder. An elastic compression block is fixedly disposed in the limiting groove. The compression end of the elastic compression block protrudes from the inner wall of the plug cylinder and the compression end of the elastic compression block is arc-shaped.

[0006] As an improvement to the above technical solution, the second light guide groove is distributed in a vertically equidistant array upwards, and the first light guide groove is distributed in an equidistant array along the bottom of the side wall of the light guide rod.

[0007] As an improvement to the above technical solution, the protective shell includes an inner shell and an outer shell. One side of the inner shell is open, and one side of the outer shell is also open. The plug-in assembly is disposed on the inner shell, and the LED beads are disposed inside the outer shell. The inner shell and the open side of the inner shell are merged to form a complete protective shell. Connecting plates are provided on the outer walls of the upper and lower sides of the inner shell, and connecting plates are also provided on the outer walls of the upper and lower sides of the outer shell.

[0010] The beneficial effects of this utility model are:

[0011] By using the light guide rod, light guide plate, light guide groove one, and light guide groove two in combination, when the LED light bead emits light, the light shines inward from the end of the light guide rod. Under the reflection of light guide groove one, the downward-shielded light is reflected upward, causing the light to refract into the light guide plate. The optical fiber entering the light guide plate will continue to be refracted by light guide groove two to the other side of the light guide plate, thus realizing a surface light source. The surface light source formed in this way not only does not produce stray light, but also forms a very uniform surface light source, greatly reducing electronic costs and the space required.

[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0020] With the increase in application scenarios, the demand for surface light sources is increasing. However, traditional ambient lights have limited application scenarios and can only achieve linear light sources with low brightness, and the effect is only good at night. To achieve a surface light source, traditional ambient lights often require a dozen to dozens of LED beads arranged in an array, which greatly increases the electronic cost and occupies a large space.

[0021] To resolve this issue, please refer to Figure 1-6 A high-power interior light includes: a pair of protective shells 10 and a light guide plate 12. A through hole 101 is provided on the opposite side of the pair of protective shells 10. An LED lamp bead 102 is provided in each of the pair of protective shells 10. The LED lamp bead 102 is located in front of the protective shell 10 inside the through hole 101. A light guide rod 11 is provided between the pair of protective shells 10. The light guide rod 11 is horizontally provided between the pair of protective shells 10. Multiple sets of light guide grooves 111 are provided at the bottom of the side wall of the light guide rod 11. The light guide plate 12 is located directly above the light guide rod 11. Multiple sets of light guide grooves 121 are provided on one side of the light guide plate 12. A light blocking plate 13 is provided on one side of the light guide rod 11. The light blocking plate 13 is located below the opposite side of the light guide grooves 121 of the light guide plate 12. The light guide grooves 121 are square and horizontal with the light guide rod 11. The opening direction of the light guide grooves 111 is perpendicular to the horizontal direction of the light guide rod 11.

[0022] The second light guide groove 121 is arranged vertically in an equal-spaced array, and the first light guide groove 111 is arranged in an equal-spaced array along the bottom side wall of the light guide rod 11.

[0023] In use, the side of the light guide plate 12 with the light guide groove 121 facing outwards is installed. Then, the remaining equipment is assembled in combination with the light guide plate 12. High-power LED beads 10 are selected to drive the LED beads 102 inside the protective shell 10 to emit light. The light emitted by the LED beads 102 enters the light guide rod 11 through the through hole 101 from both ends. The light entering the light guide rod 11 will continue to be fully reflected. When the light is refracted to the inclined surface on the light guide groove 111, the direction of light refraction is changed, causing it to be refracted into the light guide plate 12. The light guide rod 11 guides the light evenly into the light guide plate 12. The light entering the light guide plate 12 will undergo total internal reflection. When the refracted light is refracted to the side wall of the light guide groove 121, the direction of light refraction is changed due to the inclination of the side wall, causing the light to be refracted towards the side without the light guide groove 121. Thus, the light emitted by the LED beads 102 forms a surface light source through refraction.

[0024] In addition, both the light guide rod 11 and the light guide plate 12 have light reflection layers on their surfaces, so that light will continue to refract when it shines on the light reflection layers. The semi-circular rod of the light guide rod 11 facing the light guide plate 12 does not have a light reflection layer. The light guide plate 12 only has light refraction layers on the side with the light guide groove 121 and the top.

[0025] In the specific implementation process, such as Figure 4 and Figure 5 As shown, each side of the protective shell 10 is provided with a plug-in assembly 20. The plug-in assembly 20 includes a plug cylinder 21 and a baffle 24. The plug cylinder 21 is integrally disposed on the outside of the through hole 101 of the protective shell 10. The baffle 24 is disposed on the inside of the protective shell 10 and is located at the edge of the through hole 101 of the protective shell 10. The side wall of the plug cylinder 21 is provided with a limiting groove 22. An elastic compression block 23 is fixedly disposed in the limiting groove 22. The compression end of the elastic compression block 23 protrudes from the inner wall of the plug cylinder 21 and the compression end of the elastic compression block 23 is arc-shaped.

[0026] The plug-in assembly 20 is used to connect the light guide rod 11 to the protective shell 10. In use, both ends of the light guide rod 11 are inserted into the insert 21. When inserted into the insert 21, it will contact the elastic compression block 23 in the limiting groove 22. When it contacts the elastic compression block 23, it will squeeze its compression end to move outward from the limiting groove 22 and continue to insert inward. At this time, the compression end of the elastic compression block 23 will always be in contact with and squeeze the outer wall of the end of the light guide rod 11. By squeezing, the friction between it and the light guide rod 11 is increased, preventing the light guide rod 11 from slipping out of the insert 21.

[0027] Furthermore, the end of the light guide rod 11 rests against the baffle 24, so that the end of the light guide rod 11 passes through the through hole 101 and is inserted into the interior of the protective shell 10, so that when the LED lamp bead 102 emits light, the light can be refracted by the end of the light guide rod 11 into its interior.

[0028] In the specific implementation process, such as Figure 4 and Figure 5 As shown, the protective shell 10 includes an inner shell 103 and an outer shell 104. One side of the inner shell 103 is open, and one side of the outer shell 104 is also open. The plug-in assembly 20 is disposed on the inner shell 103, and the LED lamp bead 102 is disposed inside the outer shell 104. The inner shell 103 and the open side of the inner shell 103 are combined to form a complete protective shell 10. Connecting plates 105 are provided on the upper and lower outer walls of the inner shell 103, and connecting plates 105 are also provided on the upper and lower outer walls of the outer shell 104. The connecting plates 105 are provided with mounting holes 106.

[0029] The protective shell 10 is used to protect the LED lamp bead 102 and its driving components. The inner shell 103 and the outer shell 104 are separately set, so that the interior can be opened to facilitate the installation of the LED lamp bead 102 and its components. The LED lamp bead 102 and its components are connected and installed through the mounting holes 106 on the connecting plate 105. The installation method can be to use bolts and nuts for splicing and fixing.

[0030] In the specific implementation process, such as Figure 4 and Figure 5 As shown, each of the connecting plates 105 on the outer shell 104 is provided with a positioning rod 107 on one side, and each of the connecting plates 105 on the inner shell 103 is provided with a positioning hole 108 corresponding to the positioning rod 107.

[0031] In use, the positioning rod 107 and positioning hole 108 on the connecting plate 105 facilitate the alignment of the opening side of the inner shell 103 and the outer shell 104 during splicing and installation.

[0032] In the specific implementation process, such as Figure 1 and Figure 4 As shown, reinforcing ribs 109 are provided on the outer wall of the outer shell 104, and the reinforcing ribs 109 are distributed in an array.

[0033] When in use, the reinforcing ribs 109 on the outer shell 104 make the outward-facing side of the outer shell 104 more robust, thereby increasing the overall protective performance of the protective shell 10.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
