Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic weighing technology, and in particular to an illumination structure for use in electronic weighing instruments and an electronic weighing instrument. Background Technology
[0002] Modern electronic weighing instruments, such as electronic balances and various testing instruments, commonly use indicator lights and light strips as components. These components play an important role in decoration, lighting, and functional indication.
[0003] Indicator lights provide illumination while the instrument is in operation, and also serve an identification function. For example, the on / off status and different colors of the indicator lights clearly indicate the instrument's operating status. LED strips, on the other hand, are primarily used to create a spatial lighting environment, shaping an attractive display space and image while providing illumination.
[0004] However, existing LED strips have some problems. They are typically composed of a large number of LED beads, which, while providing uniform illumination, generate relatively much heat. Prolonged use of LED strips can cause significant temperature increases, which can have serious consequences for high-precision balances and other testing instruments requiring accurate measurements, leading to measurement errors and inaccurate testing.
[0005] Furthermore, the widespread use of LED beads can lead to significant power consumption. For equipment with high electrical performance requirements, such as precision instruments, this issue can affect their long-term, stable operation. Such problems limit the development of existing electronic weighing technology and reduce its applicability and reliability in many applications.

Detailed Implementation
[0035] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0036] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.
[0037] This invention is based on the analysis and improvement of existing technologies. In the prior art, electronic weighing instruments commonly use indicator lights and light strips as components, which play an important role in decoration, lighting, and functional indication. However, existing indicator lights and light strips also have some problems, mainly high heat generation, high power consumption, and complex control. These problems not only affect the performance and accuracy of the electronic weighing instrument, but also its aesthetics and user experience.
[0038] To address these issues, this invention proposes a novel lighting structure. Its main idea is to utilize light guiding principles to achieve light diffusion and uniform emission, thereby reducing the number and brightness of light-emitting elements, lowering heat generation and power consumption, while simultaneously improving visual effects and ambiance. Specifically, the lighting structure of this invention includes a light guide component and a light source component. The light guide component diffuses and guides the light emitted by the light source component to the light strip area, where it is uniformly emitted from the light-emitting end. The light source component can emit light of different colors and brightnesses according to different display and indication requirements, and these variations are achieved through control circuitry and programming.
[0039] Please refer to Figures 1 to 3 As shown, an illumination structure according to one embodiment of the present invention can be applied to an electronic weighing instrument. The illumination structure includes a light guide assembly 1 and a light source assembly 2. The light guide assembly 1 includes a main body 11 and a light guide section 12. The main body 11 has a light strip region 111 through which light can pass. The light guide section 12 includes a light incident end 121 and a light emitting end 122 corresponding to the light strip region 111. The width of the light guide section 12 gradually increases along the direction from the light incident end 121 to the light emitting end 122, guiding light incident at the light incident end 121 to exit from the light emitting end 122. The light source assembly 2 includes a main board 21 and a light emitter 22 electrically connected to the main board 21. The light emitter 22 is disposed corresponding to the light incident end 121 of the light guide section 12, so that light emitted by the light emitter 22 can enter the light guide section 12 from the light incident end 121.
[0040] Please refer to Figures 4 to 6 As shown, the light guide assembly 1 is a device that uses the principle of light guiding to achieve uniform light emission. It includes a main body 11 and a light guide part 12. The main body 11 has a light strip area 111 through which light can be transmitted. The light strip area 111 can be designed into different shapes and sizes according to the shape and size of the electronic scale, such as circular, square, elliptical, curved, etc., to adapt to different installation positions and requirements. The light guide part 12 includes a light incident end 121 and a light emitting end 122 corresponding to the light strip area 111. Along the direction from the light incident end 121 to the light emitting end 122, the width of the light guide part 12 gradually increases, that is, the light guide part 12 is generally a gradually widening fan-shaped design. This allows the light entering from the light incident end 121 to undergo multiple reflections and refractions inside the light guide part 12, thereby achieving uniform distribution and diffusion, and finally uniformly distributed throughout the entire light strip area 111. The light guide part 12 can be made of transparent or semi-transparent materials, such as glass, plastic, resin, etc., and can also have some tiny bumps or particles on its surface or inside to increase its light guiding effect.
[0041] The advantages of the light guide component 1 are that it can effectively reduce heat generation and power consumption. Due to its light diffusion effect, only a small number of light emitters 22 are needed to provide sufficient brightness, thereby reducing the impact of temperature rise on the performance and accuracy of the electronic scale. At the same time, the light guide component 1 can also improve the aesthetics and user experience of the electronic scale, as it can emit soft and uniform light, creating a good visual effect and atmosphere.
[0042] Please refer to Figure 7 As shown, the light source assembly 2 is a device that provides a light source, comprising a main board 21 and a light-emitting element 22 disposed on the main board 21. The light-emitting element 22 can be an LED bead or other type of light-emitting element, which can emit light of different colors and brightness to meet different display and indication needs. The light-emitting element 22 is disposed corresponding to the light incident end 121 of the light guide section 12, so that the light emitted by the light-emitting element 22 can enter the light guide section 12 from the light incident end 121 and be guided to the light strip area 111. Due to the light diffusion effect of the light guide assembly 1, the light-emitting element 22 only needs to provide a small amount of brightness, so only a small number of light-emitting elements need to be arranged, which can reduce power consumption and heat generation. At the same time, the light-emitting element 22 can also achieve different color and brightness changes through control circuits and programs to display different working states, measurement results, operation prompts and other information. The control circuits and programs can be designed into different modes and logics according to the functions and needs of the electronic scale, such as constant light, flashing, gradual change, breathing effects, etc., and can also be adjusted or switched according to user operation or external signals.
[0043] The motherboard 21 can integrate various circuits and chips, such as power management circuits, signal processing circuits, controllers, drivers, and power supply interfaces, to power and control the light-emitting element 22. The motherboard 21 can also be equipped with interfaces and ports, such as switches, buttons, displays, sensors, and communication modules, to enable interaction with users or external devices. The motherboard 21 can appropriately adjust and protect the light-emitting element 22 according to different operating states and environmental conditions. Simultaneously, the motherboard 21 can enhance the intelligence and scalability of the electronic scale, enabling changes in the color and brightness of the light-emitting element 22 based on user operation or external signals, and also facilitating data exchange and remote control with other devices.
[0044] The light emitter 22 is a component used to emit light. It can be an LED bead or other types of light-emitting components, such as organic light-emitting diodes (OLEDs), laser diodes (LDs), electroluminescent (ELs), etc.
[0045] In one exemplary embodiment, please refer to Figures 1 to 6As shown, the light guide portion 12 has a first light-locking surface 123 and a second light-locking surface 124 on both sides of its width direction to limit the light entering the light guide portion 12 from escaping from the side edges. The included angle between the first light-locking surface 123 and the second light-locking surface 124 is 20° to 40°. Through the design of the light-locking surfaces, the light guide portion 12 can more effectively guide light to the desired direction. The light-locking surfaces reflect the light, keeping it inside the light guide portion 12 and reducing lateral loss. The light-locking surfaces on both sides help to achieve a uniform distribution of light within the light guide portion 12, thereby achieving uniform brightness throughout the entire light strip area 111.
[0046] The light guide portion 12 has a first light-locking surface 123 and a second light-locking surface 124 on both sides of its width direction to limit the lateral scattering of light. The light-locking surfaces can be made of a highly reflective material or coated with a reflective coating. Their surfaces can be polished to maximize light reflection.
[0047] The angle between the first light-locking surface 123 and the second light-locking surface 124 can be selected and adjusted according to different light-emitting elements 22, such as type, quantity, position, and brightness. The first light-locking surface 123 and the second light-locking surface 124 can be flat or curved surfaces with a specific curvature to precisely control the direction of reflected light. When the first light-locking surface 123 and the second light-locking surface 124 are flat, the angle between them is preferably 20-40°. If the angle is too small, the light entering the light guide 12 may directly exit from the opposite side of the light strip area 111, causing uneven brightness; if the angle is too large, the light entering the light guide 12 may be repeatedly reflected near the two side edges, causing brightness attenuation. Limiting the angle between the first light-locking surface 123 and the second light-locking surface 124 to 20-40° allows the light entering the light guide 12 to be evenly distributed and diffused inside the light guide 12, thereby achieving a good light-emitting effect.
[0048] Specifically, the light guide portion 12 includes a top surface 126 and a bottom surface 127 opposite to each other in its thickness direction. The top surface 126 and the bottom surface 127 of the light guide portion 12 are curved surfaces that arch outwards towards the outside of the light guide portion 12. The top surface 126 and the bottom surface 127 of the light guide portion 12 can change the angle and direction of the light entering the light guide portion 12. They can cause the light entering the light guide portion 12 to undergo multiple reflections and refractions inside the light guide portion 12, thereby achieving uniform distribution and diffusion.
[0049] The top surface 126 and bottom surface 127 of the light guide section 12 are curved surfaces that arch outwards towards the outside of the light guide section 12. This allows light entering the light guide section 12 to produce different refraction angles on the top surface 126 and bottom surface 127, thereby increasing the propagation path and number of times it travels within the light guide section 12. The curved surface design of the top surface 126 and bottom surface 127 can effectively enhance the light guiding effect and improve the light emission quality, because they make the light emitted from the light guide section 12 more uniform and softer, thereby improving the visual effect and atmosphere. The curvature of the top surface 126 and bottom surface 127 can be selected and adjusted according to different light-emitting elements 22, such as type, number, position, and brightness.
[0050] Furthermore, the light incident end 121 has a light incident plane 125, and the light emitting body 22 has a light emitting plane 221 that matches the shape and size of the light incident plane 125. The light emitting plane 221 is aligned with and attached to the light incident plane 125.
[0051] The light incident plane 125 is a surface used to receive the light emitted by the light source 22. The shape and size of the light incident plane 125 and the light emitting plane 221 of the light source 22 can be designed according to requirements. They can be rectangular, circular, elliptical, etc., to adapt to different design and functional needs. The light incident plane 125 can effectively receive the light emitted by the light source 22 and guide it into the light guide section 12, thereby improving the light coupling efficiency and reducing light loss.
[0052] The light-emitting plane 221 is the surface on which the light-emitting body 22 emits light. It can be the outer surface of an LED bead or other type of light-emitting element, or it can be an additional transparent or translucent layer or sheet to protect the light-emitting element or change its light-emitting characteristics. The light-emitting plane 221 is aligned with and attached to the light-incident plane 125, so that the light emitted from the light-emitting plane 221 can directly enter the light guide section 12 from the light-incident plane 125 and be guided to the light strip area 111. Because the light-emitting plane 221 and the light-incident plane 125 are tightly attached with almost no gaps or gaps, reflection and scattering phenomena can be reduced, thereby reducing light loss and light leakage.
[0053] Furthermore, the light emitting end 122 is disposed in the light strip area 111 and integrally formed with the main body 11, and the light strip area 111 has a frosted surface. The integral forming of the light emitting end 122 and the main body 11 may be achieved through injection molding, 3D printing or other manufacturing processes to enhance the robustness and stability of the overall structure. The frosted surface can achieve light diffusion and scattering, thereby producing a uniform light distribution in the light strip area 111.
[0054] The light emitting end 122 is a surface used to emit light from inside the light guide 12. It is located in the light strip area 111 and integrally formed with the main body 11, thus eliminating gaps or gaps between the light guide 12 and the main body 11, thereby reducing light loss and leakage. The light emitting end 122 can be made of the same or different materials as the light guide 12 and the main body 11, such as glass, plastic, or resin. The advantage of the light emitting end 122 is that it can effectively emit light from inside the light guide 12 and form a unified whole with the main body 11, thereby improving the light emission quality and aesthetics.
[0055] The atomization treatment of the light strip area 111 can be achieved in different ways, such as sandblasting, etching, coating, etc., and can also be achieved in different degrees, such as full atomization, partial atomization, gradient atomization, etc. The advantage of atomization treatment is that it can effectively change the scattering characteristics of light, thereby making the light emitted from the light emitting end 122 softer and more uniform, thus improving the visual effect and atmosphere.
[0056] In one exemplary embodiment, please refer to Figure 2 and Figure 4 As shown, the main body 11 of the light guide assembly 1 has an illumination area 112 through which light can be transmitted. The light source assembly 2 includes an illumination source 23 disposed corresponding to the illumination area 112. The light emitted by the illumination source 23 can cover the weighing platform of the electronic scale after being transmitted through the illumination area 112. An isolation part 113 for isolating light is provided between the illumination area 112 and the light strip area 111.
[0057] The illumination area 112 is used to provide illumination for the electronic weighing instrument. It can be designed in different shapes and sizes, such as round, square, or rectangular, to suit various installation locations and needs, depending on the instrument's shape and dimensions. The illumination area 112 has light-transmitting properties and can be treated with high-gloss finishes to ensure clear and bright transmitted light. This allows the light emitted by the illumination source 23 to exit through the illumination area 112 and illuminate the instrument's work platform, display screen, control panel, and other components. The illumination area 112 can be made of transparent or translucent materials, such as glass, plastic, or resin. The advantage of the illumination area 112 is that it effectively provides illumination for the electronic weighing instrument, thereby improving its ease of use and measurement accuracy.
[0058] The lighting source 23 is positioned corresponding to the lighting area 112 so that the light emitted by the lighting source 23 can be emitted from the lighting area 112 and illuminate the working platform, display screen, operation panel, and other components of the electronic scale. The lighting source 23 can be an LED bead or other type of light-emitting element electrically connected to the main board, which can emit light of different colors and brightness to meet different lighting needs. The lighting source 23 can achieve different colors and brightness through control circuits and programs to adapt to different working states and environmental conditions.
[0059] The isolation section 113 is a component used to isolate light between the lighting area 112 and the light strip area 111. It prevents light emitted from the lighting source 23 from interfering with the light in the light strip area 111, and also prevents the light in the light strip area 111 from affecting the light transmitted through the lighting area 112. The presence of the isolation section 113 ensures that light propagates only within its corresponding area and clearly defines the boundary between the light strip area 111 and the lighting area 112. This helps achieve precise light control and avoids cross-contamination of light.
[0060] The isolation section 113 can be made of opaque or semi-transparent materials, such as metal, plastic, or resin. It can also have minute protrusions or granular structures on its surface or inside to enhance its blocking effect. The isolation section 113 can also be a through-hole structure located between the light strip area 111 and the lighting area 112, effectively blocking light transmission between the two areas. The isolation section 113 and the main body 11 can be integrated, eliminating gaps and reducing light loss and leakage. The advantage of the isolation section 113 is that it effectively isolates light between the lighting area 112 and the light strip area 111, thereby improving the light strip effect and lighting quality of the electronic scale.
[0061] Specifically, a convex structure 114 is provided on the side of the lighting area 112 near the lighting source 23. The convex structure 114 protrudes toward the side away from the lighting source 23. The lighting source 23 has a light-emitting surface that matches the shape and size of the convex structure 114. The light-emitting surface is aligned with and fits the convex structure 114.
[0062] The convex structure 114 can be used to change the refraction and reflection characteristics of light. It allows the light emitted by the illumination source 23 to produce different refraction angles on the convex structure 114, thereby achieving focusing and transmission. The convex structure 114 protrudes towards the side away from the illumination source 23, which makes the light emitted by the illumination source 23 more concentrated, thereby improving the intensity and quality of the light. The light-emitting surface of the illumination source 23 is aligned with and fits against the convex structure 114, so that the light emitted from the light-emitting surface can be directly refracted from the convex structure 114 and emitted from the illumination area 112, illuminating the working platform, display screen, operation panel, and other components of the electronic scale.
[0063] Two light strip areas 111 located on either side of the illumination area 112 can be provided on the main body 11 of the light guide assembly 1. Correspondingly, two sets of light guides 12 can be provided, with each set of light guides 12 corresponding to one of the two light strip areas 111. This allows the illumination source 23 to be located between the two sets of light guides 12, and a light-emitting element 22 for providing illumination is provided at the light incident end 121 of each set of light guides 12. In an exemplary embodiment, please refer to... Figure 2 , Figure 3 and Figure 5 As shown, the main body 11 of the light guide assembly 1 is provided with a limiting post 115, and a limiting piece 3 is fixed on the limiting post 115. The main board 21 of the light source assembly 2 is provided with a limiting groove 211 that matches the shape and size of the limiting piece 3. The limiting groove 211 penetrates the main board 21 along the thickness direction of the main board 21, and the limiting piece 3 is inserted into the limiting groove 211 along the thickness direction of the main board 21.
[0064] The limiting post 115 can be used to connect and fix the limiting piece 3. The limiting post 115 can be integrally formed on the main body 11 of the light guide assembly 1. The limiting piece 3 can be fixed to the limiting post 115 by screws. The limiting piece 3 has the characteristic of matching the shape and size of the limiting groove 211 on the main body 11, which allows the limiting piece 3 to be smoothly inserted into the limiting groove 211. The limiting piece 3 can cooperate with the limiting groove 211 and form a limiting structure with the limiting groove 211, thereby limiting the displacement of the main board 21 relative to the main body 11.
[0065] Specifically, please refer to Figures 1 to 3 As shown, an ion generator 4 is fixedly mounted on the bottom surface of the motherboard 21. The main body 11 has a mounting hole 116 that passes through the main body 11. The ion generator 4 is mounted in the mounting hole 116. The main body 11 has a first limiting rib 117 and a second limiting rib 118. The first limiting rib 117 and the second limiting rib 118 are located on both sides of the motherboard 21 along the thickness direction of the motherboard 21. The first limiting rib 117 abuts against the top surface of the motherboard 21, and the second limiting rib 118 abuts against the bottom surface of the ion generator 4.
[0066] The ion generator 4 is a device used to generate positive or negative ions. It ionizes molecules or atoms in the air through an electric field or other means, thereby producing positive or negative ions. These positive or negative ions can combine with harmful substances in the air, such as dust, germs, and odors, causing them to settle or be eliminated, thus purifying the air. Positive or negative ions can also interact with static electricity on electronic scales, eliminating static electricity and improving the measurement accuracy and stability of the electronic scales. The ion generator 4 is fixed to the bottom surface of the main board 21, allowing it to connect to electronic components such as power management circuits, signal processing circuits, and controllers. Power supply, control, and communication with the ion generator 4 are achieved through control circuits and programs. The ion generator 4 effectively improves the air purification and static electricity elimination functions of the electronic scales, thereby improving the operating environment and measurement accuracy of the electronic scales.
[0067] The mounting hole 116 is used to mount and fix the ion generator 4. It passes through the main body 11 and is located at the isolation part 113. The mounting hole 116 has an axially continuous annular structure, which allows it to accommodate ion generators 4 of different shapes and sizes. The mounting hole 116 also allows the ion generator 4 to release the generated positive or negative ions from the mounting hole 116 and distribute them evenly on the electronic scale. The ion generator 4 mounted in the mounting hole 116 can also isolate the light from the light strip area 111 and the lighting area 112.
[0068] The first limiting rib 117 and the second limiting rib 118 are components used to limit the relative position and orientation between the main body 11 and the main board 21. They are provided on the main body 11 and located on both sides of the main board 21 along the thickness direction of the main board 21.
