Description

Pick up light {FISH GATHERING LAMP}

TECHNICAL FIELD The present invention relates to a catch for catching squid, saury, sardines, horse mackerel and the like.

Conventional incandescent lamps, such as incandescent lamps using halogen, metal halogen lamps, because the light utilization efficiency is poor, consume a large amount of fuel oil, the load on the environment is a problem due to a large amount of CO ₂ emissions. In addition, excessively dazzling light which is irradiated in various directions and can also be confirmed from satellites becomes light sea, and the adverse effect of light containing ultraviolet rays on the human body is a problem. Among them, recently, a light lamp using LED as a light source has been proposed.

For example, Patent Document 1 uses two LED planar light sources and combines the right surface light source for irradiating the sea surface on the right side of the ship and the left surface light source for irradiating the sea surface on the left side of the ship, thereby effectively irradiating the sea surface. The intent is described.

[Patent Document 1] Japanese Patent Laid-Open No. 2003-134967

However, the fishing lamp described in patent document 1 aims at improving the utilization efficiency of light mainly by simply irradiating light from LED to sea surface effectively, and paying attention to the change of the illuminance distribution in the sea by the shaking of a ship body. I'm not doing it.

In other words, in conventional fishing, the illuminance distribution in the sea changes due to the shaking of the ship, making it difficult to attract catches such as squids, saury, sardines, horse mackerels, or the like. There was a problem.

A fishing lamp according to the present invention is a fishing lamp installed on the hull to illuminate the sea surface,

The said pick-up lamp has a light distribution pattern which has a 1st light distribution peak from a horizontal direction below and a 2nd light distribution peak from a horizontal direction upwards in the state which has no shaking in the said ship body in the one plane orthogonal to the said sea surface, It is characterized by the above-mentioned. .

Since the pick-up lamp according to the present invention configured as described above has the first light distribution peak and the second light distribution peak in the light distribution pattern, a change in relative intensity within the maximum swing angle range of the hull centered on the light distribution center angle. It is possible to reduce the size, and even if the hull is shaken within the maximum swing angle, it is possible to reduce the change in the illuminance far away from the hull.

Moreover, in the pick-up lamp etc. which concerns on this invention, it is preferable to make intensity of the said 1st light distribution peak smaller than the intensity of the said 2nd light distribution peak, and, thereby, can change a roughness change of ship body vicinity.

The collecting lamp includes an LED serving as a light source and a light distribution control member for controlling light distribution of the light from the LED. The light distribution control member includes a first light distribution control region for controlling light distribution from the LED to the first light distribution peak side. And a second light distribution control region for controlling light distribution of the light from the LED on the second light distribution peak side, and a third light distribution control region between the first light distribution control region and the second light distribution control region. In this case, the first light distribution peak is formed by partially overlapping the light controlled in the first light distribution control region and the light controlled in the third light distribution control region, and the second light distribution peak is controlled by the light controlled in the second light distribution control region. The light controlled in the three light distribution control regions is formed by partially overlapping.

When viewed from one end surface such as picking up, it is preferable that the light distribution control member includes a plurality of convex portions in the first light distribution control region and a plurality of convex portions in the second light distribution control region.

According to the present invention, since the change in the illuminance distribution in the sea due to the shaking of the ship can be suppressed, it is possible to make the picking-up of the picking-up ability more improved.

EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated, referring drawings. However, the form shown below is an illustration for actualizing the technical idea of this invention, and this invention is not limited to the following.

(Embodiment 1)

1, the pick-up lamp 10 which concerns on this embodiment is shown. (a) is a perspective view, (b) is sectional drawing in X-X in one cross section of (a). The pick-up lamp 10 includes a substrate 11, an LED 12 serving as a light source disposed on the substrate 11, a case 13 in which the substrate 11 is placed, and light distribution of light from the LED 12. It has the light distribution control member 14 to control. The light distribution control member 14 is fixed to the case 13 with a screw or the like, but is not particularly shown here.

FIG. 2 shows a light distribution pattern of the catching lamp 10 in FIG. 1B in one cross section (the left and right directions in FIG. 1B correspond to the left and right directions in FIG. 2). In Fig. 2, the horizontal axis represents angle, and the vertical axis represents relative emission intensity ratio (relative intensity). The light distribution pattern of the collecting lamp 10 includes a first light distribution peak P1 and a second light distribution peak P2 which are different from each other when viewed from one cross section (a first light distribution peak P1 that becomes a maximum value and a second light distribution peak P2 that becomes a maximum value). Has a minimum value between and). Specifically, when the pick-up lamp 10 is installed in the hull, the first light distribution peak below the horizontal direction (direction parallel to the sea level) and the first above the horizontal direction in the state where there is no shaking in the hull. 2 light distribution peaks. The first light distribution peak P1 is configured to be smaller than the second light distribution peak P2.

As a result, even when the hull is shaken, the sea surface far away from the hull can always be irradiated (light can be sent to the sea far away from the hull), so that changes in the illuminance distribution in the sea can be effectively suppressed. Therefore, by changing the distribution of illuminance in the sea, it is possible to alleviate the problem that it is difficult to attract the captures or the scattered captures are scattered again.

The light distribution pattern of the collecting lamp 10 is continuously changing. In Fig. 2, the relative intensity increases from 0 near -60 degrees to the maximum value (first light distribution peak P1) near -20 degrees, the minimum value near -5 degrees, and the maximum value near +20 degrees (second light distribution peak P2). The relative strength is going down to 0 near +60 degrees. By restricting the light distribution pattern to +/- 60 degrees, the light distribution pattern is used in which the above-described effects are not impaired. However, the light distribution pattern of the present invention is not limited to the range of approximately ± 60 degrees, and may be set to, for example, ± 80 degrees or ± 70 degrees depending on the installation situation (installation angle) such as an assumed hull angle or picking up. It is also possible to change the angle of the negative (-) side and the angle of the positive (+) side.

Hereinafter, based on FIG. 3, it demonstrates how the change of the illuminance distribution in the sea can be suppressed by the structure of this invention.

3 is a light distribution image diagram from the hull in which the fishing lamp 10 is mounted. 3, (a) is a light distribution image of the hull without shaking, (b) is a light distribution image of the hull at -20 degrees (left in the drawing), (c) is a +20 degree of hull ( (Right side in the figure) is an image of light distribution in a tilted state. For ease of understanding, the light corresponding to the first light distribution peak P1 in FIG. 2 is P1, and the light corresponding to the second light distribution peak P2 in FIG. 2 is P2 (P1 and P2 are solid lines and others. Dashed lines).

Fig. 4 shows the illuminance distribution in the sea in the case of Figs. 3A to 3C. The vertical axis represents the depth of water, and the horizontal axis represents the distance from the hull. Here, the roughness distribution in the state where the hull is not shaken (FIG. The illuminance distribution in a state where +20 degrees is tilted (FIG. 3C) is indicated by a dashed-dotted line (c). Here, also for easy understanding, the light corresponding to the first light distribution peak P1 in FIG. 2 is P1 and the light corresponding to the second light distribution peak P2 in FIG. 2 is P2.

First, in this embodiment, as shown in FIG. 4, the illuminance in the sea from a distant place (for example, 50 m or more from a hull) is not changed. This is realized by having the light distribution characteristic provided with two peaks P1 and P2 at the position where the pick-up lamp of this embodiment was separated.

For example, in the present embodiment, assuming that the hull is inclined up to ± 20 °, and the inclination of the hull is within a range of ± 20 °, as shown in Figs. The light distribution characteristic including the interval between the two peaks P1 and P2 and their intensities is set so that the relative intensity of the light irradiated on the surface is not smaller than 0.7.

On the other hand, for example, as shown in (1) to (3) of FIG. 12, in a fishing lamp having one peak, as shown in FIG. 12, the light to irradiate the surface of the reference point P far away from the hull is shown. The relative strength drops to about 0.6 or 0.5 when the hull is inclined up to ± 20 °.

Therefore, in the pick-up lamp etc. which have one peak as shown to (1)-(3) of FIG. 12, as shown in (4) of FIG. 12, the relative of the light which irradiates the surface of the reference point P far from a ship body The strength is greatly reduced when the hull is inclined up to ± 20 °.

In addition, in the graph of FIG. 12 (4), the solid line of a shows the illuminance distribution with respect to the distance from the hull in the state where there is no inclination, and the broken line of b is the distance from the hull when the hull is inclined by -20 °. Roughness distribution is shown, and the dashed-dotted line of c shows the roughness distribution with respect to the distance from a ship body when a ship body inclined +20 degrees.

In addition, the light distribution characteristic of the pick-up lamp etc. which are the comparative examples which have one peak as shown to (1)-(3) of FIG. 12 is obtained by removing the light distribution control member 14 from the pick-up lamp of this embodiment.

Hereinafter, the pick-up of this embodiment etc. is demonstrated in detail.

For example, in the present embodiment, the first light distribution peak P1 is controlled to be lower than the horizontal direction (direction parallel to the sea surface) in the state where the hull is not shaken, and the second light distribution peak P2 is higher than the horizontal direction. It is controlled so that it may be (FIG. 3A). Thus, in a state where the hull is not shaken, the sea surface near the hull is irradiated by the light of the first light distribution peak P1, and the light between the first light distribution peak P1 and the second light distribution peak P2 is far from the hull. Sea level is investigated. At this time, the illuminance distribution in the sea becomes the same as the solid line (a) of FIG.

At this time, the light between the 1st light distribution peak P1 and the 2nd light distribution peak P2 which irradiates the sea surface of the reference point P far from a ship body has a comparatively high relative angle of 0.7 or more even if it is a minimum value (FIG. 9 (1 ) Reference).

Further, when the hull is inclined at -20 degrees (left side in FIG. 3), light of the first light distribution peak P1 is irradiated to the surface of the ship nearer the hull, and light of the second light distribution peak P2 is irradiated to the surface of the ship far away ( (B) of FIG. 3). Thereby, even if the ship body is inclined as shown in FIG.3 (b), light can be irradiated to the sea surface far from a ship body by the light of the 2nd light distribution peak P2. At this time, the illuminance distribution in the sea becomes the same as the dotted line (b) of FIG. 4.

At this time, the light irradiating the sea surface of the reference point P far from the hull has a relatively high relative intensity of about 0.8 exceeding the 2nd peak (refer FIG. 10 (7)).

Further, when the hull is inclined at +20 degrees (right side in Fig. 3), the light of the first light distribution peak P1 is irradiated to the sea surface far away from the hull, and the light of the second light distribution peak P2 is shown in FIGS. 3A and 3B. It is irradiated more upward compared to Thereby, even if the ship body is inclined as shown in FIG.3 (c), light can be irradiated to the sea surface far from a ship body by the light of 1st light distribution peak P1. At this time, the illuminance distribution in the sea becomes the same as dashed-dotted line (c) in FIG.

At this time, the light irradiating the surface of the reference point P far from the hull is almost the first peak light, and has a relatively high relative intensity of about 0.8 (see FIG. 11 (7)).

As shown in Fig. 4, in the fishing lamp of the present invention, it is possible to minimize the change in the illuminance distribution in the sea away from the hull due to the inclination of the hull. That is, even when the hull is in an inclined state (dashed line (b) and dashed-dotted line (c) in FIG. 4), light can be irradiated to the sea surface far away from the hull at all times, and the illuminance distribution from the far place can be made substantially constant. . Also in the vicinity of the ship body, by making the first light distribution peak P1 smaller than the second light distribution peak P2, it is possible to minimize the change in the illuminance distribution in the sea.

This is because the intensity of light is inversely proportional to the square of the distance from the hull. That is, in the region far from the hull, a difference in the depth of light hitting is unlikely to occur due to the difference between the magnitudes of the first light distribution peak P1 and the second light distribution peak P2 (also in any of (a) to (c) in FIG. 4). Light is reaching from the hull at a distance of 100 m to the sea in about 10 m). In the vicinity of the hull, by making the first light distribution peak P1 smaller than the second light distribution peak P2, the change in the illuminance distribution is effectively suppressed as compared with the case where both are the same size (the intensity of light is inversely proportional to the square of the distance from the hull). In the vicinity of the hull, slight differences in light distribution peaks will significantly affect the illuminance distribution).

In addition, although the above description demonstrated the illuminance distribution in the sea and the sea vicinity of the hull in the case where there is no inclination of the hull, and when the inclination is inclined by +/- 20 degrees, the hull is ± 5 °, ± 10 °, ± 15. Relative intensities of light irradiating the reference point P at a distant point when tilted are shown in Figs. 10 (1) to (6) and 11 (1) to (6).

Hereinafter, the structure of the pick-up lamp of this embodiment is demonstrated.

An enlarged view in the vicinity of the LED of FIG. 1B is shown in FIG. 5 (in FIG. 5, the case 13 is not shown). LED 12 is arrange | positioned on the board | substrate 11, and the light distribution control member 14 is provided facing the LED 12. As shown in FIG. The light distribution control member 14 includes a first light distribution control region for controlling light distribution of the light from the LED 12 to the first light distribution peak side, and a second light distribution control side for controlling light distribution of the light from the LED 12 to the second light distribution peak side. And a second light distribution control region and a third light distribution control region between the first light distribution control region and the second light distribution control region.

6 shows a light distribution image in FIG. 5. 8, the first light distribution characteristic d1 distributed by the first light distribution control region, the second light distribution characteristic d2 distributed by the second light distribution control region, and the third light distribution distributed by the third light distribution control region. The characteristic d3 and the light distribution characteristic td of the whole pick-up lamp which they piled up are shown. 6 and 8, the first light distribution peak P1 is partially overlapped with the light (first light distribution) controlled in the first light distribution control region and the light (third light distribution) controlled in the third light distribution control region. The second light distribution peak P2 is formed by partially overlapping the light (second light distribution) controlled in the second light distribution control region and the light (third light distribution) controlled in the third light distribution control region. Thereby, although the structure is relatively simple, the light distribution pattern which has the 1st light distribution peak P1 and the 2nd light distribution peak P2 can be obtained.

The light distribution control member 14 includes a plurality of convex portions in the first light distribution control region, and a plurality of convex portions in the second light distribution control region. That is, by forming a plurality of notches in the longitudinal direction (direction perpendicular to the line segment XX) in FIG. 1A (not specifically shown in FIG. 1A), a plurality of convex portions are formed in cross section. ((B) of FIG. 1, see FIG. 5). Each convex part has a different shape, thereby controlling the light distribution of the light from LED12.

By forming a plurality of convex portions in the first light distribution control region and the second light distribution control region, the thickness of the light distribution control member 14 itself can be made thinner as compared with the light distribution control member of the second embodiment, and therefore, warpage due to heat or the like Can be suppressed. When warpage occurs in the light distribution control member 14, there is a problem that the light distribution pattern changes, or when a physical force is applied to suppress the warpage, cracks occur in the light distribution control member itself. Therefore, by making thickness of the light distribution control member 14 into the structure which has a some convex part, the possibility of these problems can be largely reduced.

In addition, in this embodiment, since the inclination of a ship body is the maximum at +/- 20 degree | times, the 1st light distribution peak P1 is set to -20 degree vicinity, and the 2nd light distribution peak P2 is set to +20 degree vicinity. . However, the angle of each peak may be determined in consideration of the inclination of the hull assumed, and is not limited to the angle of the present embodiment.

In this embodiment, since the surface (substrate surface) of the board | substrate 11 becomes a perpendicular direction (direction perpendicular | vertical to a sea surface) when the picking lamp 10 is installed in a ship body, it is perpendicular | vertical to a board | substrate surface, The light distribution pattern as seen from one cross section coincides with the light distribution pattern of the pick-up lamp 10 from the hull. However, the light distribution pattern such as picking up may be determined in consideration of the installation situation on the ship body, and it is not necessary to necessarily match the vertical direction with the substrate surface.

In the present embodiment, an example in which two light distribution peaks of a first light distribution peak and a second light distribution peak are described as the light distribution pattern of the collecting lamp 10 is described, but the present invention is not limited thereto. That is, when the hull is inclined to the maximum, any one of the second light distribution peak and the first light distribution peak should be irradiated with the sea surface of a distant place (see (b) and (c) of FIG. 3), for example. You may have a 3rd light distribution peak between them. However, in the case where the third light distribution peak is provided between them, the light of the second light distribution peak and the third light distribution peak is irradiated in the air without irradiating the sea surface in the state of FIG. It is not preferable at this point. Therefore, as shown in the present embodiment, there is a first light distribution peak and a second light distribution peak, and in the state where the hull is inclined to the maximum, the surface of the distant surface can be irradiated with one of the first light distribution peak and the second light distribution peak. It is desirable to be controlled so that it is controlled.

Hereinafter, the main component of the fishing lamp 10 which concerns on this embodiment is demonstrated.

(Substrate 11)

Although the board | substrate 11 is not specifically limited, In this embodiment, what is called a printed board in which predetermined wiring pattern was given between layers as a multilayer structure is used. A printed board is preferable because it has high versatility and can easily form a desired wiring pattern.

(LED (12))

The light source is not particularly limited, but for example, the LED 12 can be used as in the present embodiment. In consideration of the visibility of the capture, an LED of a desired wavelength may be used. For example, since the maximum visibility wavelength of a water squid is 480 nm-490 nm vicinity, when the target catch object is a water squid, LED which has the emission spectrum of 480 nm-490 nm vicinity can be used.

(Case (13))

Various materials and the thing of various structures can be used for the case which accommodates the board | substrate 11. In this embodiment, the main component of the case 13 is made aluminum, and the heat from the LED 12 is dissipated effectively. Moreover, heat dissipation can also be improved by making the bottom part of the case 13 into fin shape, and ensuring a large surface area.

(Light distribution control member 14)

The light distribution control member 14 is for controlling light distribution of the light from the LED 12 and is formed of a resin such as PC (polycarbonate). Here, the first light distribution peak P1 and the second light distribution peak P2 which are different from each other are formed by the light distribution control member 14. However, compared to the present embodiment, more complicated work is required, but for example, a plurality of LEDs having different light distribution patterns and light emission intensities are arbitrarily arranged to include different first light distribution peaks P1 and second light distribution peaks P2. It is also possible to make a light distribution pattern.

(Embodiment 2)

In the present embodiment, only the light distribution control members 24 are different from each other, and the other configuration is common to the pick-up lamp 10 according to the first embodiment. The light distribution control member 24 shown in FIG. 7 is a so-called cylindrical lens, and has one surface small curved to obtain the first light distribution peak P1 (left of FIG. 7), and to obtain the second light distribution peak P2. The other side has a large curved surface (right side in FIG. 7), and both are integrally formed with a step. Even in such a configuration, a light distribution pattern as shown in FIG. 4 can be obtained.
