Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a strip light. Background Technology

[0002] Currently, most strip lights on the market employ a structure where the internal light-emitting part uses a side light source in conjunction with reflective paper and a light guide plate. This allows the light emitted from the side light source to be scattered and reflected by the light guide plate and reflective paper, thereby reducing the overall thickness of the light fixture. However, in existing strip lights, the width of the reflective paper is generally set to meet the basic requirements for reflecting light. Since the reflective paper is set with the light guide plate as the sole reference, its width only covers the width of the light guide plate, but does not extend to the side light source. This results in some loss of light efficiency and side light leakage in dark environments, affecting visual consistency. Utility Model Content

[0003] The present invention aims to solve the technical problems in the prior art mentioned above, and proposes a strip light, the specific technical solution of which is as follows:

[0004] A strip light includes: a housing; an illumination module disposed within the housing, wherein the illumination module includes a lamp panel disposed on the inner sidewall of the housing, a light guide plate facing the lamp panel, and reflective paper disposed below the light guide plate, the reflective paper extending below the lamp panel; and a control system for controlling the lamp panel.

[0005] Furthermore, the light guide plate is made of polystyrene and has two surfaces, upper and lower, with reflective textures on both surfaces.

[0006] Furthermore, it also includes a polycarbonate cover, which is disposed on the light guide plate.

[0007] Furthermore, the control system includes: a circuit board for electrical connection with the lamp panel; multiple control buttons connected to the circuit board for pressing to adjust the lighting effect; a battery for providing power to the lamp panel and the circuit board; and a DIP switch for controlling the opening and closing of the battery supply to the lamp panel and the circuit board.

[0008] Furthermore, the control buttons include a mode switching button for switching the control mode of the strip light.

[0009] Furthermore, the control buttons include a color temperature and brightness switching button, used to switch between color temperature adjustment mode and brightness adjustment mode.

[0026] The following discloses various implementations or embodiments of the described subject matter. To simplify the disclosure, specific examples of elements and arrangements are described below. These are merely examples and are not intended to limit the scope of protection of this application. For example, a first feature subsequently described in the specification being formed above or on a second feature can include implementations where the first and second features are formed in a direct connection, or implementations where an additional feature is formed between the first and second features, thus the first and second features may not be directly connected. Furthermore, reference numerals and / or letters may be repeated in different examples in these disclosures.

[0027] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0028] refer to Figures 1 to 4In some embodiments, the strip light 100 includes: a housing 1; an illumination module 2 disposed in the housing 1, wherein the illumination module 2 includes a light panel 21 disposed on the inner sidewall of the housing 1, a light guide plate 22 facing the light panel, and a reflective paper 23 disposed below the light guide plate, the reflective paper 23 extending below the light panel 21; and a control system 3 for controlling the light panel 21. The light panel 21 generally includes LED beads as the light source. The light panel 21 emits light towards the side of the light guide plate 22. After entering the light guide plate 22, the light is evenly diffused by the internal scattering dots of the light guide plate 22. Some light rays are emitted from the upper surface of the light guide plate towards the main light output direction, while unused light rays penetrate the light guide plate 22 and scatter downwards. At this time, the widened reflective paper 23 extending below the light panel 21 totally reflects this scattered light (especially the high-intensity direct light near the LED beads) upwards, allowing these light rays to re-enter the light guide plate 22 to participate in light output, thus avoiding light loss or side light leakage.

[0029] In some embodiments, the light guide plate 22 is made of polystyrene and has two surfaces, upper and lower, with reflective textures on both surfaces. The reflective textures can be injection molded or implemented in other ways. The reflective textures are integrally formed with the light guide plate 22, eliminating interface reflection loss, achieving high mold processing precision, and ensuring that the dot shape and depth consistency far surpasses laser point-to-point engraving. Furthermore, the injection-molded structure has a smooth surface, reducing light scattering loss.

[0030] like Figures 5 to 7 As shown, in some embodiments, the reflective texture may be a microlens array 221 (hemispherical dots), a prism array 222 (V-groove / corner pyramid prism), or other structures. Figure 5 The schematic diagram of the microlens array 221 is shown in detail. Its surface is distributed with millions of micron-sized (typically 10μm–50μm in diameter) hemispherical bumps or pits. The density is dynamically adjusted with the distance from the light source (the dots are larger and the spacing is denser at the distance from the light source). Its optical function is to prevent the light from being uniformly scattered from the front by breaking the total internal reflection (TIR) ​​of the light inside the light guide plate, thus avoiding the generation of dark areas. Figure 6 The schematic diagram of the prism array 222 is shown in detail. The prism array 222 can be etched on one or one side of the light guide plate 22, and the brightness can be enhanced in a directional manner by utilizing the refraction and light-concentrating effect of the prism. Figure 7The diagram schematically illustrates that the microlens array 221 and the prism array 222 are respectively injection molded on the upper and lower surfaces of the light guide plate 22. The light guide plate 22 can also employ combinations of other arrays or structures, such as combining hemispherical dots with prism structures, for example, using high-density V-grooves on the light-incident side to enhance light capture, and transitioning to scattering dots in the middle to optimize uniformity.

[0031] The advantages of using polystyrene material for the light guide plate 22 are its cost-effectiveness and low-temperature processing friendliness, making it an ideal choice for room-temperature lighting products. The double-sided reflective texture, through bidirectional optical control, creates a uniform light output while reducing manufacturing complexity. This combination of polystyrene material and reflective textures on both sides significantly improves the product's cost-effectiveness while ensuring luminous efficiency, making it particularly suitable for the strip light 100.

[0032] refer to Figures 1 to 4 In some embodiments, a polycarbonate cover 24 is also included, which is disposed on the light guide plate 22. The polycarbonate cover 24 increases the uniformity of light through secondary scattering, and the polycarbonate cover 24 has high toughness, protecting the internal optical components of the strip light 100, extending its service life, and ensuring that the strip light 100 emits stable light in complex environments.

[0033] refer to Figures 1 to 4 In some embodiments, the control system 3 includes: a circuit board 31 for electrical connection to the lamp panel 21; multiple control buttons connected to the circuit board 31 for pressing to adjust the lighting effect; a battery 32 for providing power to the lamp panel 21 and the circuit board 31; and a DIP switch 33 for controlling the opening and closing of the battery 32's power supply to the lamp panel 21 and the circuit board 31. This structure is simple and reliable. The control buttons are physical buttons, easy to operate, and not easily damaged. The DIP switch 33 provides physical power cutoff, which helps avoid standby power consumption and short circuit risks, and extends battery life. The battery 32 eliminates the need for wiring and is easy to repair and replace. The circuit board 31 can also integrate a wireless control module for remote control of the strip light 100 to achieve various adjustment functions.

[0034] refer to Figures 1 to 4In some embodiments, the control buttons include a mode switching button 34 for switching the control mode of the strip light. The control mode may include a bright daytime mode and a dim nighttime mode, or other modes. In bright ambient light conditions, such as during the day, the strip light 100 requires higher light intensity, and dimmer light is generally not used. Therefore, it can be adjusted to daytime mode, making the light intensity adjustable within the bright light range. In dim ambient light conditions, such as at night, the strip light 100 requires dimmer light to avoid glare caused by a large difference in light intensity between the strip light and the ambient light, which would affect the user experience. Therefore, it can be adjusted to nighttime mode, making the light intensity adjustable within the dim light range. These two modes allow users to choose according to the corresponding environment, improving adjustment efficiency and enhancing the user experience.

[0035] refer to Figures 1 to 4 In some embodiments, the control buttons include a color temperature and brightness switching button 35, used to switch between color temperature adjustment mode and brightness adjustment mode. The color temperature and brightness switching button 35 can be used to switch between the two modes of adjusting color temperature and adjusting brightness, saving the number of buttons, simplifying the operation logic, and making it easy for users to use.

[0036] refer to Figures 1 to 4 In some embodiments, the control buttons include a level adjustment button 36 for adjusting color temperature and brightness. The level adjustment button 36 can be used to adjust the color temperature in color temperature adjustment mode and to adjust the brightness in brightness adjustment mode, thus saving on the number of buttons. The level adjustment button 36 can be adjusted by pressing, rotating, or moving up, down, left, or right.

[0037] refer to Figures 1 to 4 In some embodiments, a small plug 4 and a large plug 5 are also included. The small plug 4 is used to close the top of the strip light 100, and the large plug 5 is used to close the bottom of the strip light 100. The large plug 5 is provided with an opening for multiple control buttons to pass through. The small plug 4 and the large plug 5 make the strip light 100 compact, less prone to dust accumulation, and improve durability and aesthetics.

[0038] refer to Figures 1 to 4 In some embodiments, at least one single-sided magnet 6 is disposed within the housing 1 for magnetic adsorption mounting of the strip light 100. One, two, or more single-sided magnets 6 can be provided, and their number and position can be flexibly set according to the different sizes and shapes of the strip lights 100, facilitating adsorption onto metal objects, easy assembly and disassembly, and wide applicability.

[0039] refer to Figures 1 to 4In some embodiments, at least one mounting piece 7 is disposed on the outside of the housing 1 for fixed installation of the strip light 100. One, two, or more mounting pieces 7 may be provided, and their number and position can be flexibly set according to the different sizes and shapes of the strip lights 100, facilitating installation on objects with corresponding slots and increasing the fixing strength.

[0040] The strip light 100 provided by this utility model effectively intercepts and utilizes the lateral direct light from the LED beads through total internal reflection by extending the reflective paper 23 below the light panel 21, significantly improving brightness and eliminating light leakage in dark environments. The light guide plate 22, made of polystyrene and featuring a double-sided microstructure texture design, improves light uniformity, enhances the efficiency of recovering downward-scattered light, and reduces overall cost. The control system adopts a physical button direct control architecture with ergonomic and intuitive operation logic. The entire light uses a modular quick-release structure, supporting rapid manual assembly and disassembly to meet the needs of various usage scenarios.
