After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value has finally been created.

[0046] Please refer to Figures 1 to 4 This utility model provides a long-distance detection light source device, including a housing 1, a light-emitting plate 2, a light-amplifying component 3, and a light-amplifying plate 4.

[0047] The housing 1 has a strip-shaped light outlet 11. A light-emitting lamp plate 2 is installed in the housing 1 to emit light into the strip-shaped light outlet 11, and includes a plurality of lamp bead groups 21 arranged in a spaced array along the extension direction of the strip-shaped light outlet 11. A light-amplifying assembly 3 is installed in the housing 1, and includes a plurality of light-amplifying lens groups 31 corresponding one-to-one with the plurality of lamp bead groups 21. A light-amplifying plate 4 is installed on the light-emitting side of the light-amplifying assembly 3 and closes the strip-shaped light outlet 11; one side of the light-amplifying plate 4 is provided with an array of light-amplifying strip-shaped protrusions, and the extension direction of the light-amplifying strip-shaped protrusions is perpendicular to the extension direction of the strip-shaped light outlet 11.

[0048] In this embodiment, the housing 1 is used to position and support the light-emitting plate 2. The light emitted from the light-emitting plate 2 passes sequentially through the light-amplifying component 3 and the light-amplifying plate 4. The light-amplifying component 3 includes several light-amplifying lens groups 31 that correspond one-to-one with several LED bead groups 21, thereby significantly increasing the range of light emitted by the LED beads. The illumination range here includes not only the width range but also the length range. It should be noted that the length direction refers to the direction of the linear light spot parallel to the extension direction of the strip light-emitting port 11, while the width direction is perpendicular to the length direction.

[0049] In this embodiment, the light emitted from the LED bead group 21 on the light-emitting plate 2 is amplified by the light-expanding lens group 31 and then directed onto the light-expanding plate 4. The light-expanding strip protrusion on the light-expanding plate 4, which is perpendicular to the extension direction of the strip light-emitting port 11, can further diffuse the light along the extension direction of the strip light-emitting port 11, forming a trumpet-shaped light-emitting illumination effect, making the total length of the linear light spot significantly longer than the total length of the long-distance detection light source device. In addition, the combined structure of the light-expanding strip protrusion and the light-expanding lens group 31 makes the light diffusion effect better, which is conducive to improving the uniformity of the linear light spot.

[0050] Optionally, the cross-section of the light-amplifying strip protrusion is fan-shaped on a plane perpendicular to its extension direction. A fan-shaped cross-section results in a more uniform light amplification effect. Specifically, the height of the light-amplifying strip protrusion can be adjusted according to the desired effect, thereby changing the actual light amplification effect.

[0051] Optionally, the light-expanding lens group 31 includes a first light-expanding lens 311 and a second light-expanding lens 312; the first light-expanding lens 311 and the second light-expanding lens 312 are sequentially spaced apart along a direction away from the light-emitting lamp panel 2, and the light-expanding lens group 31 is located on the light-emitting side of the corresponding lamp bead group 21; in the corresponding lamp bead group 21, the first light-expanding lens 311 and the second light-expanding lens 312, the optical axis of the lamp bead group 21, the center line of the first light-expanding lens 311 and the center line of the second light-expanding lens 312 coincide with each other. In this embodiment, the light-expanding effect can be effectively improved by the first light-expanding lens 311 and the second light-expanding lens 312 expanding the light twice, so that the light illumination range is larger. However, it should be noted that since the strip light-emitting port 11 is a flat and elongated light-emitting port, part of the light diffused in the width direction will be blocked by the housing 1, thus ultimately forming a strip light-emitting effect. In this embodiment, the first light-expanding lens 311 and the second light-expanding lens 312 are both plano-convex lenses, with the planar side facing the corresponding lamp bead group 21 and the convex side facing the strip light-emitting port 11.

[0052] Optionally, the light-amplifying assembly 3 further includes a first support plate group 32 and a second support plate group 33; the first light-amplifying lens 311 is mounted on the first support plate group 32, and the second light-amplifying lens 312 is mounted on the second support plate group 33, so that the first light-amplifying lens 311 and the second light-amplifying lens 312 can be fixed at different heights.

[0053] Optionally, the first support plate group 32 includes a support base plate 321 and a pressing top plate 322, and the first support plate group 32 forms a first light-emitting hole corresponding to the lamp bead group 21.

[0054] The first light-expanding lens 311 is positioned and pressed by the supporting base plate 321 and the pressing top plate 322, thereby achieving more precise positioning and fixation. In addition, the first light-expanding lens 311 blocks the first light-emitting hole, so that all emitted light rays must pass through the first light-emitting hole, thereby improving the light-expanding effect.

[0055] In one specific embodiment, the maximum width of the light-amplifying lens group 31 is A; the width of the light-amplifying strip protrusion is less than 0.1A. Specifically, based on actual testing results, the light-amplifying effect is better when the width of the light-amplifying strip protrusion is approximately 0.1A. Figure 4 In the image, you can see the light-expanding stripe protrusions.

[0056] Optionally, the light-diffusing plate 4 also includes a flat plate portion supporting the light-diffusing strip protrusion; a perforation is formed between the flat plate portion and the light-diffusing strip protrusion. The perforation improves airflow heat dissipation and prevents the light-diffusing plate 4 from overheating. The light-diffusing strip protrusion can be located at the top or bottom of the flat plate portion, as long as it effectively diffuses light.

[0057] Optionally, the lamp bead group 21 is an LED lamp bead group 21.

[0058] Optionally, the edges of two adjacent light-expanding strip protrusions are joined together.

[0059] Optionally, a cooling fan 5 is also installed on the housing 1. The cooling fan 5 can blow air onto the housing 1 to prevent the housing 1 from getting too hot.

[0060] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
