According to the utility model, the distance between the concave body formed by the concave area and the peripheral surface of the shell and the liquid luminescent material is different, so that the brightness difference is generated, and the closer the distance to the liquid luminescent material is, the higher the brightness of scattered light is; therefore, a three-dimensional pattern formed by the concave bodies forms a visible light spot pattern on a projection plane of a horizontal plane due to brightness difference between the light of the scattered liquid luminescent material and the light scattered in the peripheral surface area of the shell, and due to no light shielding, the light emitting efficiency is high, and the light emitting pattern effect is clear and not blurred.

Description

Technical Field

[0001] This utility model relates to the field of liquid light-emitting device technology, and in particular to a light spot pattern light-emitting device. Background Technology

[0002] Liquid light-emitting devices are commonly used as decorative items or toys. Liquid light emission typically involves a liquid containing a fluorescent agent emitting fluorescence under short-wavelength light or a liquid undergoing a chemiluminescent reaction to produce visible light. Due to the fluidity of the liquid, the fluorescence or chemiluminescence effect differs from that of solid-state light-emitting devices such as filaments or LEDs. Typical liquid light-emitting devices have a housing containing a sealed liquid. To display graphics or patterns, the device's shape is usually used to represent the image; published patent CN2544375Y demonstrates this method. However, this method of scattering light through the device's shape has limitations: some device shapes lack sufficient contrast in light scattering, resulting in blurry images; and the varied housing shapes make modular assembly difficult. Another method of achieving luminous graphics or patterns involves creating light contrast through external or internal obstruction of the device. Published patents CN103225746B and CN2660292Y use this method to display luminous patterns. However, this method of blocking light through obstruction results in some light loss, making it less efficient than other light-emitting devices.

[0003] Therefore, there is an urgent need for a new light spot pattern emitting device to solve the above-mentioned technical problems. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, the existing liquid light-emitting devices have problems such as insufficient contrast of scattered light and blurry pattern effect when using the shape of the device to scatter light, and the shell shape is different and it is difficult to modularly assemble them together. In addition, the display of light-emitting patterns by blocking the light through pattern devices results in low light efficiency due to the loss of some light.

[0005] To this end, the present invention provides a light spot pattern light-emitting device, which consists of a shell and a liquid light-emitting material contained inside, wherein a portion of the surface of the shell has one or more recessed areas in the direction of inward movement.

[0006] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the housing is made of a translucent milky material.

[0007] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the direction in which the recessed area is recessed into the housing is perpendicular to the horizontal plane of the liquid light-emitting material.

[0008] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the depth of the recessed area recessed into the housing is 40%-80% of the total height of the housing in the recessed direction.

[0009] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, at least one area of ​​the recessed body formed by the recessed area recessing into the shell is immersed in the liquid light-emitting material.

[0010] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the side wall of the recessed body formed by the recessed area recessing into the housing forms an inclined angle with the direction of the recess.

[0011] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the cross-section of the recessed body is an inverted trapezoid.

[0012] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, the cross-section of the recessed body is an inverted triangle.

[0013] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, when there are two or more recessed areas, the recessed areas are located on the surfaces of the shell in different directions.

[0014] In a specific embodiment of the above-mentioned light spot pattern light-emitting device, when there are two recessed areas and the housing is hexahedral in shape, the two recessed areas are respectively disposed on two opposite surfaces of the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a recessed area on the housing. The difference in light scattering brightness between the recessed area and the surrounding housing surface, created by the varying distances between the recessed area and the liquid luminescent material, results in a higher brightness of scattered light. This difference in brightness between the recessed area and the surrounding housing surface creates a visible light spot pattern on the horizontal projection surface. Since the light spot pattern formed by this light intensity contrast is unobstructed, the efficiency of the entire device is improved, and the luminous pattern is clear and unblurred. Furthermore, because the recessed area is within the outer contour of the housing, the housing can be designed as a regular, integrated structure, facilitating the assembly of multiple devices.

[0030] This utility model relates to the field of liquid light-emitting device technology, and in particular to a light spot pattern light-emitting device. The purpose is to solve the problems of existing liquid light-emitting devices that use the device's shape to scatter light, resulting in insufficient contrast and blurry patterns; the difficulty in modularly assembling the varied shapes of the housings; and the low luminous efficiency caused by blocking light transmission through patterned devices. To address these issues, the light spot pattern light-emitting device provided by this utility model consists of a housing and an internal liquid light-emitting material. A portion of the housing surface has one or more recessed areas extending inwards. This utility model utilizes these recessed areas to create a difference in brightness between the recessed areas and the surrounding housing surface at different distances from the liquid light-emitting material. The closer the recess is to the liquid light-emitting material, the brighter it is. This difference in brightness, caused by the light scattering from the liquid light-emitting material onto the horizontal projection surface of the three-dimensional pattern formed by the recessed areas, contrasts with the light scattered from the surrounding housing surface, creating a visible light spot pattern. Since the light spot pattern formed by the light intensity contrast is not obstructed, the overall efficiency of the device is improved.

[0031] The light spot pattern light-emitting device provided in the embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] See Figure 1-7 This invention provides a light spot pattern luminescent device, comprising a housing 1 and a liquid luminescent material 2 contained within it. A portion of the surface of the housing 1 has one or more recessed areas 3 extending inwards. The housing 1 is configured to scatter the light emitted by the liquid luminescent material 2; for example, the housing 1 is made of a translucent milky-white material. The projection of the three-dimensional pattern formed by the recessed areas 3 into the housing on a horizontal plane creates a brightness difference between the light scattered by the liquid luminescent material 2 and the light scattered by the surrounding surface area of ​​the housing 1, thus forming a light spot pattern. In this application, the light spot pattern is the projection of the recessed area onto a horizontal plane; adjusting the shape of the recessed area adjusts the shape of the light spot pattern.

[0033] Figure 1-2The light-emitting device shown is a square hexahedral shell 1. The top surface of shell 1 has an inwardly recessed area 3. The three-dimensional shape formed by the recessed area extending inwards from the shell appears as a radial four-pointed star on the horizontal projection plane. From... Figure 2 As shown in the AA cross-sectional view, the shell 1 contains liquid luminescent material 2. The direction of the recessed area into the shell 1 is perpendicular to the horizontal plane of the liquid luminescent material 2, which is more conducive to creating a difference in brightness. The light emitted by the liquid luminescent material 2 is diffused in all directions, passing through the shell 1 and making the entire shell 1 appear bright. The upward light passes through the top of the square hexahedral shell 1, while the light passing through the bottom of the four-pointed star is closer to the liquid luminescent material 2. Therefore, when viewed from above, the brightness of the bottom of the four-pointed star is higher than that of the upper surface of the shell 1, creating a difference in brightness and thus highlighting the light spot pattern of the four-pointed star.

[0034] In the above embodiments, to create a noticeable light spot effect, the recessed area 3 is designed to be recessed into the housing 1 to a depth of 40%-80% of the total height of the housing 1 in the recessed direction. This depth has yielded good results through testing. Preferably, the recessed depth is 60% of the total height of the housing 1, at which point the highlighted light spot pattern effect is optimal. Furthermore, the distance between the edge of the recessed area 3 and the edge of the housing 1 is greater than or equal to a set value, such as 1 mm. This application does not specifically limit this distance; it is set based on the actual structure of the housing 1 and the recessed area, as well as the experimental results.

[0035] In one embodiment, see Figure 2 The side wall 4 of the recessed body formed by the recessed region 3 recessing into the shell forms an inclined angle with the direction of the recess. Figure 2 As shown, the sidewall 4 of the recessed body is inclined towards the center of the recessed region 3, for example, at an angle of 30° or 45°. Thus, when light is scattered on the inclined sidewall, the brightness of the light scattered on the inclined surface gradually changes with the distance between the rising slope and the liquid luminescent material 2, thereby creating a gradual difference in brightness between the four-pointed star-shaped light spot pattern and the top surface of the shell 1. Different gradient effects of light spot patterns can be obtained by varying the inclination angle, enriching the types of light spot patterns. The specific value of the angle is not specifically limited in this application; it is set according to the actual desired light spot pattern effect. Furthermore, experiments have shown that the best light spot effect is obtained when the cross-section of the recessed body is an inverted trapezoid or an inverted triangle.

[0036] This application utilizes different distances from the liquid luminescent material 2 to create differences in brightness to highlight the light spot pattern. The light spot pattern formed in this way is not formed by an occlusion effect and does not block the light, so it outputs the energy of the light to the maximum extent.

[0037] In one embodiment, see Figure 3-4 At least one area of ​​the recessed body formed by the recessed region 3 extending into the shell 1 is immersed in the liquid luminescent material 2. The area immersed in the liquid luminescent material 2 is equivalent to having zero distance between it and the liquid luminescent material 2, and the light scattered in this part is the brightest.

[0038] Figure 3-4 The structure of the light-emitting device shown is similar to Figure 1-2 The illustrated embodiments are essentially the same, except that the liquid luminescent material 2 inside the housing 1 partially submerges the recess, effectively making the distance between the recess and the liquid luminescent material 2 zero. The light scattered in this portion is the brightest. This allows adjustment of the brightness difference between the recess and the surrounding surface area by changing the depth of the submersion, thus enabling a clearer display of the light spot pattern.

[0039] It should be noted that this application does not specifically limit the number of recessed regions 3 or the number of immersed portions in the liquid luminescent material 2, but allows for flexible setting based on the desired light spot pattern. Furthermore, the distribution area of ​​the recessed regions on the shell 1 is also not specifically limited, and can be flexibly set based on the desired light spot pattern. For example, multiple recessed regions 3 with different depths can be set on the shell 1, with each recessed region 3 immersed at a different depth in the liquid luminescent material 2, resulting in different brightness levels for the light spot pattern corresponding to each recessed region 3. Alternatively, some recessed bodies may be deeply immersed in the liquid luminescent material 2, while others may be shallower and not immersed at all. These differences in immersion depth and distance create brightness differences, allowing for a richer and more diverse light spot pattern when these recessed bodies are observed as a whole and their patterns are visually combined.

[0040] In one embodiment, when there are two or more recessed areas 3, these recessed areas 3 are located on the surfaces of the housing 1 in different directions.

[0041] For example, when there are two recessed areas 3 and the shell 1 is hexahedral in shape, the two recessed areas 3 are respectively provided on two opposite surfaces of the shell 1.

[0042] For example, when there are two recessed areas 3 and the shell 1 is cylindrical, the two recessed areas 3 are respectively provided on two opposite end faces of the shell 1.

[0043] by Figure 5-7 The structure shown will be explained in detail. For example... Figure 5-7As shown in the figure, the structure of the light-emitting device is a cylindrical shell 1. Two recessed areas 3 are provided at each end of the cylinder. The three-dimensional shape formed by the recessed areas 3 at one end projects a heart shape onto the horizontal plane, while the three-dimensional shape formed by the recessed areas 3 at the other end projects a pentagon onto the horizontal plane. As can be seen from the AA cross-sectional view, the shell 1 contains liquid light-emitting material 2. When different cylindrical end faces are rotated upwards, different light spot patterns, either heart-shaped or pentagonal, can be seen from the top of the end faces. Setting heart-shaped and pentagonal recesses on two opposite end faces of the hexahedron can achieve the same light spot pattern effect as setting recesses on the cylindrical end faces. Of course, recessed areas 3 can also be set on multiple end faces of the hexahedron; by changing the recessed areas 3 on different faces, different light spot patterns can also be obtained.

[0044] In the above embodiments, the liquid luminescent material can be provided from a hydrogen peroxide-bis(oxalate) system based on a binary chemiluminescence reaction, or from a liquid fluorescent material. Alternatively, flowable granular luminescent materials can also be used in this device to obtain luminescent spot patterns.

[0045] This invention utilizes recessed areas with specific shapes and contours on a shell, causing light to scatter from the shell at varying distances, resulting in brightness differences and forming light spot patterns of specific shapes. This method avoids light obstruction, has high luminous efficiency, and produces clear, unblurred luminous patterns. Through design and experimentation, various shells with recesses were manufactured using 3D printing technology, and after injecting liquid luminescent material, all achieved excellent light spot image rendering effects.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
