Description

Technical Field

[0001] The invention relates to the field of aquatic equipment, and in particular to a metal halide fish attracting lamp with a reflective device. Background Art

[0002] Fishing boats use lights to attract fish in marine fishing production, taking advantage of the fish's phototaxis to attract fish schools to the vicinity of fishing boats for fishing, which is a common means of fishing operations. The energy cost consumed by light-induced fish attracting accounts for an important proportion of the comprehensive cost of fishing. Metal halide fish attracting lamps are the most commonly used fish attracting lamps in current marine fishing production.

[0003] The fish attracting lights used for light-luring fish are usually hung above the side of the ship. The light of traditional fish attracting lights is evenly distributed in all directions, and the effective utilization rate of light energy irradiated on the water surface and underwater is very low, which needs to be further improved through technical improvements.

[0004] In addition, part of the light from the fish attracting lamp will shine obliquely upwards and towards the sky. This part of the light cannot be effectively utilized, further reducing the energy efficiency of the fish attracting lamp.

[0005] Due to the low energy efficiency of fish attracting lights in the prior art, the energy consumption of fish attracting lights accounts for a large proportion of the energy consumption of fishing boats. The electrical energy on fishing boats is usually generated by fuel oil. For fishing boats operating in the ocean, the cost of fuel oil is much higher than that on land, so it is necessary to improve the energy efficiency of fish attracting lights.

[0006] The light energy from fish-attracting lights on the deck of fishing boats not only does not contribute to fishing production, but also generates strong light pollution and high heat on the deck, seriously damaging the health of deck workers and should be protected through technical means. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the present invention provides a metal halide fish attracting lamp with a reflective device, which reduces damage to human health and achieves energy saving without changing the effect of attracting and catching fish.

[0008] In order to achieve the above object, the present invention provides a metal halide fish attracting lamp with a reflective device, comprising a lamp holder suspended on a gantry line of a fishing boat deck and a metal halide lamp in the shape of a cylindrical rod installed at the bottom of the lamp holder and pointing vertically downward;

[0009] In addition, a side reflector with a circular arc plate-shaped horizontal section is arranged on the back of the metal halide lamp facing away from the ocean surface; the side of the side reflector facing the metal halide lamp is a side reflective surface, and the two sides of the side reflector are curved in the direction where the metal halide lamp is located, and the surface of the side reflective surface is a reflective film and an anti-corrosion film in sequence; the distance (B) between the metal halide lamp and the side reflective surface of the side reflector in the horizontal section is 0.2-0.8 times the curved surface radius (R) of the side reflector of the side reflector;

[0010] The side of the lamp holder is surrounded by a top reflector that is obliquely upward and shaped like a flanged hat brim; the circumferential length of the top reflector along the lamp holder is complementary to the circumferential length of the side reflector, forming a circle, or the two sides of the top reflector extend to above the top edges of the two sides of the top reflector; the surface of the top reflector facing obliquely downward is the top reflective surface, and the surface of the top reflective surface is provided with a reflective film.

[0011] By adopting this technical solution, a side reflector with a circular arc-shaped plate in horizontal cross-section is set on the back of the metal halide lamp facing away from the ocean, which almost blocks the light and heat that are not directed to the ocean but are irradiated on the deck in vain, thereby avoiding the harm of high temperature exposure to light to fishermen on the boat.

[0012] The relationship between the distance between the metal halide lamp and the side reflective surface of the side reflector in the horizontal section and the radius of the curved surface of the side reflector of the arc-shaped side reflector is very important and very sensitive. The metal halide lamp is a cylindrical rod-shaped vertical hanging assembly, and the light is emitted in all directions. The brightness of the upper and lower ends of the lamp tube is weak, and it is mainly concentrated in the middle band, irradiating to a long distance, forming an aperture, light band, and light layer.

[0013] When the metal halide lamp is located at the center of the arc of the lateral reflective surface of the side reflector, the intensity of the irradiated light band is enhanced. As the ship rises and falls during navigation, the fluctuation of this light band will be amplified, causing large-scale shaking over a long distance, which is not conducive to luring fish and fishing.

[0014] When the metal halide lamp is located at a distance beyond the center of the arc of the lateral reflective surface of the side reflector, that is, B is greater than R, the gathering effect of the reflective surface is weakened and lost, the reflective effect is very poor, and the energy collection and energy saving effect is not achieved.

[0015] According to theoretical calculation and actual test, within the range set by the present invention, the focusing effect of the reflective surface is weakened, forming a wide-angle reflection, which is beneficial to fishing. It can achieve a significant energy-saving effect. Moreover, the irradiated and reflected light bands increase a certain range and have a suitable brightness, so the effect of luring fish is particularly prominent.

[0016] As mentioned above, the metal halide lamp of the present invention is in the shape of a cylindrical rod and emits light in all directions. The brightness of the upper and lower ends of the lamp tube is weaker and that of the middle is stronger. Although the light at the top is weaker, it is a waste to illuminate the sky. The present invention is provided with a top reflector shaped like a cap brim which is tilted upward at the opening of the side reflector. It not only covers the waste of sky illumination, but also designs and selects a certain tilted upward angle, so that the light irradiated upward by the gold tooth lamp is reflected by the tilted surface of the top reflector and shines into the sea surface below the ship, thereby increasing the induction of fish in the irradiated area and improving the fishing volume.

[0017] A further improvement of the present invention is that the distance between the center of the metal halide lamp and the lateral reflective surface of the side reflector in the horizontal section is 0.5-0.6 of the curvature radius of the lateral reflective surface of the arc-shaped side reflector, and the distance is calculated from the reflective surface side.

[0018] A further improvement of the present invention is that the top edge of the side reflector is horizontally bent toward the side where the side reflective surface is located to form a connecting edge, and the connecting edge is fixedly connected to the bottom of the lamp holder by screws.

[0019] A further improvement of the present invention is that the vertical length of the lamp side reflector is greater than the vertical length of the metal halide lamp.

[0020] A further improvement of the present invention is that the upward oblique angle (α) of the reflective surface of the top reflector is 10-30 degrees.

[0021] A further improvement of the present invention is that the bottom edge of the top reflector extends inwardly to form a connecting edge, and the connecting edge is fixedly connected to the bottom surface of the lamp holder by bolts.

[0022] A further improvement of the present invention is that the top reflector is a thin shell structure, and an anti-corrosion film is provided on the upper surface of the thin shell structure.

[0023] The beneficial technical effects of the present invention are:

[0024] (1) The shape of the side reflector and the positional relationship between the metal halide lamp and the side reflective surface make the light reflected by the side reflector more dispersed, so that the light beam emitted by the fish attracting light has a certain directionality and a larger illumination range, which can cover a larger sea surface area. When the fishing boat bumps or the fish attracting light swings, the illumination range formed on the sea surface has better continuity, which is convenient for fish tracking and has a better fish attracting effect;

[0025] (2) The top reflector can reflect part of the light emitted obliquely upwards downwards and shine it towards the sea surface, thereby improving the effective utilization rate of light energy and saving energy while maintaining the original light energy level required for production.

[0034] The following is based on the attached Figure 1 , give the preferred embodiments of the present invention, and describe them in detail so that the functions and features of the present invention can be better understood.

[0035] See also Figure 1 As shown, the embodiment of the present invention includes a metal halide fish attracting lamp with a reflective device, which includes a lamp holder 1 suspended on the side rail of the fishing boat deck and a metal halide lamp 2 in the shape of a cylindrical rod installed at the bottom of the lamp holder 1 and pointing vertically downward. A coaxial light emitting body 4 is arranged in the middle of the metal halide lamp 2, and the light emitting body 4 is the main light emitting part of the fish attracting lamp.

[0036] like Figures 1 to 3 As shown, the main difference between the metal halide fish attracting lamp and the prior art is that a side reflector 3 with a circular arc plate-shaped horizontal section is arranged on the back of the metal halide lamp 2 facing away from the ocean surface; the side of the side reflector 3 facing the metal halide lamp 2 is a side reflective surface, and its two sides are bent in the direction of the metal halide lamp 2, so that the horizontal section of the side reflective surface of the side reflector 3 is a circular arc.

[0037] The side of the lamp holder 2 is surrounded by a top reflector 5 that is tilted upward and has a flanging brim. The circumferential length of the top reflector 5 along the lamp holder 2 is complementary to the circumferential length of the side reflector 3, forming a circle (such as Figure 1 2), or the two sides of the top reflector 5 extend above the top edges of the two sides of the side reflector 3 to cover the tops of the two sides of the side reflector 3 (as shown in FIG. Figure 8 The surface of the top reflector 5 facing obliquely downward is the top reflective surface, and a reflective film is provided on the surface of the top reflective surface.

[0038] like Figure 1 and Figure 7As shown, the lower surface of the top reflector 5 is the side surface of the rotating body, and the intersection line of the reference plane passing through the axis of the metal halide lamp 2 and the top reflective surface of the top reflector 5 is a straight line. The top reflector 5 is used to reflect the light emitted obliquely upward by the light emitting body 4 obliquely downward and illuminate the sea surface. In this embodiment, in order to ensure the reflective effect of the top reflector 5, the oblique upward angle (α) of the reflective surface of the top reflector is 10-30 degrees.

[0039] The side reflector 3 is made of polymer by injection molding process, and the surface of the side reflective surface of the side reflector 3 is a reflective film and an anti-corrosion film from the inside to the outside. The distance B between the center (axis) of the metal halide lamp 2 and the side reflective surface of the side reflector 3 on the horizontal section is 0.2-0.8 times the radius of curvature (R) of the side reflective surface of the side reflector (3). When the shape and position of the metal halide lamp 2 and the side reflector 3 are fixed, the distance B is the minimum distance between the metal halide lamp 2 and the side reflector 3. The side reflector 3 can reflect the light generated by the metal halide lamp and directed to the deck to the sea surface, thereby avoiding light pollution and heat on the deck, and improving the energy efficiency of the fish attracting lamp.

[0040] In the prior art, the reflector usually adopts a parabolic cross-section, and the lamp is set at the focus of the reflector, which makes the reflected light of the reflector more focused, but this reflector is not suitable for use on fishing boats. When the fishing boat is bumped by the waves or the fish-collecting lamp swings, the over-focused light beam will quickly pass over the sea surface, making it difficult for the fish to track and reflect, and the fish-collecting effect is poor. In this embodiment, the shape of the side reflector 3 and the positional relationship between the metal halide lamp 2 and the lateral reflective surface make the light reflected by the side reflector more dispersed, so that the light beam emitted by the fish-collecting lamp has a certain directionality and a larger illumination range, which can cover a larger sea surface area. When the fishing boat is bumped or the fish-collecting lamp swings, the illumination range formed on the sea surface has better continuity, which is convenient for fish tracking and has a better fish-collecting effect.

[0041] In this embodiment, the distances between the two sides of the side reflector 3 and the metal halide lamp 2 are equal, and the plane passing through the two side edges of the side reflector 3 passes through the metal halide lamp 2. The top edge of the side reflector 3 is horizontally bent toward the side where the side reflective surface is located to form a connecting edge, and the connecting edge is fixedly connected to the bottom of the lamp holder 1 by screws. The vertical length of the lamp side reflector 3 is greater than the vertical length of the metal halide lamp 2. A gap 6 extending vertically is provided in the middle of the lamp side reflector 3. The gap 6 can prevent the reflected light from passing through the luminous body of the metal halide lamp 2 again, causing it to further accumulate heat, and is also conducive to heat dissipation at the highest temperature of the reflector (the position where the gap 6 is set is closest to the metal halide lamp 2).

[0042] like Figure 4As shown, in a specific embodiment, the distance B between the metal halide lamp 2 and the side reflective surface of the side reflector 3 in the horizontal section is the distance between the central axis of the tubular metal halide lamp 2 and the vertical central axis of the side reflective surface. The distance B is 0.5-0.6 times the radius R of the curved surface of the side reflector 3. According to theoretical calculation and actual test, within the range set by the present invention, this distance range can achieve a significant energy-saving effect. Moreover, the irradiated and reflected light bands are increased to a certain extent and have a suitable brightness, so the effect of luring fish is particularly prominent.

[0043] and Figure 4 compared to, Figure 5 The minimum distance between the metal halide lamp 2 and the side reflector 3 is close to the curvature radius R of the side reflective surface, which makes the reflected light of the side reflector 3 more concentrated. Figure 6 Another comparison is shown. Figure 6 In the structure shown, the minimum distance between the metal halide lamp 2 and the side reflector 3 is greater than the radius R of the side reflective surface, which makes the side reflector 3 unable to effectively reflect the light emitted by the metal halide lamp 2, and the light emitted by the metal halide lamp 2 to the side and rear cannot be reflected. Figure 5 and Figure 6 In the situation shown, the fish attracting lamp cannot fully utilize the light, has high energy consumption, and is not conducive to attracting fish and catching fish.

[0044] like Figure 1 , 7 As shown, the top edge and the bottom edge of the top reflector 5 are both arc-shaped. The bottom edge of the top reflector 5 extends inward to form a connecting edge, and the connecting edge is fixedly connected to the bottom surface of the lamp holder 1 by bolts. The top reflector 5 is a thin shell structure, and an anti-corrosion film is provided on its upper surface.

[0045] The present invention is described in detail above in conjunction with the embodiments of the accompanying drawings. A person skilled in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the present invention, and the scope of protection of the present invention shall be defined by the scope of the attached claims.
