Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a light-emitting panel, a light source module, and an LED fish-attracting lamp. Background Technology

[0002] Fish-attracting lights play a crucial role in the fisheries industry, significantly improving fishing efficiency. Currently, traditional fish-attracting lights mostly use halogen lamps, metal halide lamps, and high-pressure sodium lamps. These light sources generally result in high power consumption, low energy efficiency, and a limited spectrum, leading to limited fish-attracting effects. LED lights have been a research hotspot in recent years, but their application still faces some challenges. Most existing LED fish-attracting lights have uneven beam distribution, easily producing strong light spots and dark areas. This uneven illumination causes fish to gather only in specific illuminated areas, reducing fish-attracting efficiency. Furthermore, LED fish-attracting lights generally lack refined optical structure design, making it difficult to effectively control the direction and angle of the light, resulting in a more diffuse beam and reduced light guidance and targeting. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a light-emitting panel that can effectively control the light-emitting direction and eliminate the problem of uneven light spots.

[0004] The technical problem to be solved by this utility model is to provide a light source module and an LED fish-attracting lamp with good light spot uniformity.

[0005] To solve the above-mentioned technical problems, this utility model provides a light-emitting panel, including a first light-incident surface, a second light-incident surface, and a light-emitting surface. The first light-incident surfaces are arranged in a longitudinal array, and the second light-incident surfaces connect two adjacent first light-incident surfaces. The projections of two adjacent first light-incident surfaces onto the light-emitting surface are continuous and do not overlap. The distance from the first light-incident surface to the light-emitting surface changes monotonically along the array direction of the first light-incident surfaces.

[0006] As an improvement to the above solution, the second light incident surface is arranged perpendicular to the light exit surface.

[0007] As an improvement to the above scheme, the intersection of the first light incident surface and the transverse section is a wavy line.

[0008] As an improvement to the above scheme, the crest and trough segments of the wave line are arranged in a rotationally symmetrical manner.

[0009] As an improvement to the above scheme, the intersection of the second light incident surface and the longitudinal section is a line segment.

[0010] As an improvement to the above scheme, the angle between the first light incident surface and the light exit surface is 20~75°.

[0011] As an improvement to the above scheme, the ratio of the maximum distance from the first light incident surface to the light emitting surface to the minimum distance from the first light incident surface to the light emitting surface is 1.5~3.5:1.

[0012] In addition, this utility model also provides a light source module, which includes a light source board and the aforementioned light-emitting panel. The light source board is provided with an LED light-emitting unit, and the light incident surface on the light-emitting panel is arranged opposite to the LED light-emitting unit.

[0013] In addition, this utility model also provides an LED fish-attracting lamp, which includes the above-mentioned light source module, as well as a power supply, an optical lens and a housing. The light source module and the power supply are both disposed in the closed cavity formed by the optical lens and the housing, and the light-emitting panel is disposed opposite to the optical lens.

[0014] As an improvement to the above solution, at least two light source modules are provided, and the light-emitting surfaces of two adjacent light source modules form a preset angle.

[0015] Implementing this utility model has the following beneficial effects:

[0016] This utility model discloses a light-emitting panel. The panel comprises a first light-incident surface, a second light-incident surface, and a light-emitting surface. The first light-incident surfaces are arranged in a longitudinal array, and the second light-incident surfaces connect adjacent first light-incident surfaces. The projections of adjacent first light-incident surfaces onto the light-emitting surface are continuous and non-overlapping. Furthermore, the distance from the first light-incident surface to the light-emitting surface monotonically changes along the array direction of the first light-incident surfaces. This allows most of the light to be refracted through the first light-incident surfaces, effectively deflecting the light. After multiple refractions and reflections, the light is evenly distributed on the light-emitting surface, preventing excessively bright light spots or excessive energy concentration. When passing through the light-emitting surface, the light beam is effectively guided outward. For marine fish-attracting lights, the emitted light can be effectively guided to the sea surface, concentrating more light on the water surface and the target area below.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] As shown in Figures 1 to 6, this utility model discloses an embodiment of a light-emitting panel, including a first light-incident surface 1, a second light-incident surface 2, and a light-emitting surface 3. The light-emitting surface 3 is a smooth plane. The first light-incident surfaces 1 are arranged in a longitudinal array. The second light-incident surface 2 connects two adjacent first light-incident surfaces 1. The projections of two adjacent first light-incident surfaces 1 onto the light-emitting surface 3 are continuous and do not overlap. The distance from the first light-incident surface 1 to the light-emitting surface 3 changes monotonically along the array direction of the first light-incident surfaces 1, that is, it increases monotonically or decreases monotonically.

[0026] In this embodiment, the light-emitting panel is configured with a first light-incident surface 1, a second light-incident surface 2, and a light-emitting surface 3. The first light-incident surfaces 1 are arranged in a longitudinal array, and the second light-incident surfaces 2 connect two adjacent first light-incident surfaces 1. The projections of two adjacent first light-incident surfaces 1 onto the light-emitting surface 3 are continuous and do not overlap. Furthermore, the distance from the first light-incident surfaces 1 to the light-emitting surface 3 varies monotonically along the array direction of the first light-incident surfaces 1, so that most of the light is refracted by the first light-incident surfaces 1. The first light-incident surfaces 1 can effectively deflect the light, and after multiple refractions and reflections, the light can be evenly distributed on the light-emitting surface 3, avoiding excessively bright light spots or excessive energy concentration. When passing through the light-emitting surface 3, the light beam is effectively guided outward. For marine fish-attracting lights, the emitted light can be effectively guided to the sea surface, allowing more light to concentrate on the water surface and the target area below.

[0027] Preferably, the second light incident surface 2 is arranged perpendicularly to the light exiting surface 3. Since the projections of two adjacent first light incident surfaces 1 onto the light exiting surface 3 are continuous and do not overlap in this embodiment, and the second light incident surface 2 is arranged perpendicularly to the light exiting surface 3, the amount of light incident through the second light incident surface 2 will be minimized. The first light incident surface 1 serves as the main light incident surface, ensuring that the vast majority of light enters the light emitting panel through the first light incident surface 1.

[0028] More preferably, the intersection of the second light incident surface 2 and the longitudinal section is a line segment, that is, the second light incident surface 2 is a plane set perpendicular to the light exit surface 3. In this case, the light illuminating the light-emitting panel from the front will not be directly refracted by the second light incident surface 2. Most of the light will be refracted sequentially by the first light incident surface 1 and the light exit surface 3 to form a parallel beam before being emitted, which has good guidance.

[0029] To ensure that most of the light rays illuminating the light-emitting panel are refracted sequentially through the first light incident surface 1 and the light exit surface 3 to form a parallel beam before being emitted, in this embodiment, the angle between the first light incident surface 1 and the light exit surface 3 is preferably 20~75°, and the ratio of the maximum distance from the first light incident surface 1 to the light exit surface 3 to the minimum distance from the first light incident surface 1 to the light exit surface 3 is 1.5~3.5:1.

[0030] In this embodiment, based on the horizontal stripe structure formed by the first light incident surface 1 and the second light incident surface 2, a fine microstructure design is further incorporated into the first light incident surface 1. The intersection line of the first light incident surface 1 and the horizontal section is set as a wavy line. That is, the main light incident surface of each horizontal stripe structure adopts a wavy texture, which can fine-tune and scatter the light, making the light spot transition softer and avoiding the problems of concentrated light spots and obvious bright streaks that occur in traditional lighting.

[0031] Preferably, the peaks of two adjacent first light incident surfaces 1 are staggered to improve the uniformity of light output.

[0032] In this embodiment, the wavy line at the intersection of the first light incident surface 1 and the transverse section has its crest and trough segments arranged in a rotationally symmetrical manner and with a smooth transition, so as to make the light uniformity better.

[0033] If necessary, a light-shielding coating or a reflective coating can also be provided on the second light incident surface 2. In this case, all the light from the light source passing through the light-emitting panel will enter through the first light incident surface 1.

[0034] The material used for the light-emitting panel in this embodiment is preferably polycarbonate, which has the characteristics of high light transmittance, strong toughness, temperature resistance and lightweight.

[0035] Furthermore, this utility model also provides an embodiment of a light source module, which includes a light source board and the aforementioned light-emitting panel. The light source board is provided with an array of LED light-emitting units, and the first light-incident surface 1 on the light-emitting panel is disposed opposite to the LED light-emitting units. The light emitted by the LED light-emitting units can be effectively deflected by the first light-incident surface 1. After multiple refractions and reflections, the light can be evenly distributed on the light-emitting surface 3, avoiding excessively bright light spots or excessive energy concentration. When passing through the light-emitting surface 3, the light beam is effectively guided outward. The light emitted by the LED light-emitting units is adjusted by the first light-incident surface 1 and microstructure on the light-emitting panel to achieve reasonable polarization of the incident light, thereby effectively controlling the light emission angle and light intensity distribution, and improving the uniformity and directionality of the light beam.

[0036] In this embodiment, the light-emitting panel is provided with a light-emitting cavity 4. Both the first light-incident surface 1 and the second light-incident surface 2 are disposed within the light-emitting cavity 4. A first connecting hole 5 is provided on the outer periphery of the light-emitting cavity 4, and a connecting post 6 is provided inside the light-emitting cavity 4. The connecting post 6 has a second connecting hole 61. The first connecting hole 5 and the second connecting hole 61 are used to connect to the light source board and / or other lighting components. The connection post 6 and the second connecting hole 61 improve the reliability of the light source module assembly.

[0037] Furthermore, this utility model also provides an embodiment of an LED fish-attracting lamp. This embodiment is a long, strip-shaped LED fish-attracting lamp, which uses an LED light source and the aforementioned light-emitting panel to form a light source module. Compared with existing fish-attracting lamp products, the LED light source used in this embodiment has the advantages of high power, high energy efficiency, long lifespan, and easy maintenance.

[0038] The LED fish-attracting light specifically includes the aforementioned light source module, as well as a power supply, an optical lens, and a housing. The light source module and the power supply are both housed within a closed cavity formed by the optical lens and the housing. The light-emitting panel is positioned opposite the optical lens. The housing is fixed using a metal bracket. The light source module, through adjustments to the first light incident surface 1 and microstructure on the light-emitting panel, achieves proper polarization of the incident light, thereby effectively controlling the light emission angle and intensity distribution, and improving the uniformity and directionality of the light beam.

[0039] The LED fish-attracting light in this embodiment uses the aforementioned light source module, and its light spot effect exhibits a uniform and soft light distribution with natural transitions at the edges of the light spot and no obvious distinction between light and dark areas. At the same time, the brightness at the center of the light spot is sufficient, ensuring adequate illumination of the target area. This light spot effect helps to improve the lighting effect, making the light in the entire fish-attracting area more uniform, thereby improving the fish-attracting efficiency.

[0040] In addition, by designing optical lenses, namely the microstructure formed by the first light incident surface 1 and the second light incident surface 2 of the light-emitting panel, reasonable polarization of the incident light is achieved, directing more light to the water surface and the area below, ensuring that the light spot is evenly distributed in the target area; the wave pattern microstructure design of the first light incident surface 1 can effectively deflect and soften the light, eliminating obvious bright spots in the light spot.

[0041] In this embodiment, the emitted light from the LED fish-attracting light can be effectively directed to the sea surface, concentrating more light on the target area above and below the water. It is suitable for various operating scenarios, providing lighting solutions for fishing operations at different depths and in different waters.

[0042] Preferably, at least two light source modules are provided, and the light-emitting surfaces of two adjacent light source modules form a preset angle. In this embodiment, the angle between the light-emitting surfaces of two light source modules is set to 90°, realizing bidirectional light emission, significantly widening the illumination range of the light, and enhancing the coverage effect of the light.

[0043] The light distribution curve and spatial isolux curve of the LED fish-attracting lamp in this embodiment were tested, and its light pattern is shown in Figure 7. The left figure shows an average beam angle of 138.2 degrees, providing a relatively wide illumination range, suitable for large-area lighting applications. The red curve shows the symmetry of light intensity in the horizontal direction, while the green curve shows that the light intensity is higher near the water surface. The right figure shows the illuminance distribution range of the lamp at different heights, indicating that the lamp has a wide-angle beam and uniform light intensity distribution, suitable for occasions requiring large-area lighting.

[0044] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
