Description

  The present invention relates to a fishing light having an LED light source.

  Conventionally, metal halide lamps have been mainly used for fish collection in fishing and sightseeing fishing boats, and it has been said that the luminous efficiency is the most effective.However, on the other hand, a huge amount of lighting fuel is required, and depending on the case, In some cases, more fuel was required than the navigation fuel to the fishing grounds.

  For this reason, recently, fish-collecting lights based on LEDs have appeared instead of this, but without the producer fully understanding the elements and remorse items necessary for fish-collecting, it is not always necessary to concentrate on only producing a large amount of light It is hard to say that high efficiency results have been achieved, and it can be said that the fact that LED fish lamps have not been widely used in place of existing models even after considerable time has passed since their appearance.

  Up to now, there has been proposed a device for improving the harvesting efficiency with a fish-collecting lamp utilizing the directivity strength and the easy setting of the emission wavelength, which are the characteristics of the LED (for example, Patent Documents 1 to 5 described below). reference).

  However, these conventional LED fishlights tend to adopt a multi-lamp type instead of a single light source, which requires a large amount of light, in which case it is necessary to install the light sources at a distance from each other so as not to collect heat. The resulting heat dissipation also concentrates on the back of the appliance, which has the disadvantage of increasing the size of the appliance. Since the luminous efficiency of the LED decreases when the temperature rises with the light emission, and the LED itself deteriorates due to the temperature rise, sufficient heat radiation is important.

  The conventional LED fish light, which tended to be large, did not fully consider the weight of the fish light installed at high places compared to the total weight and form of the ship, and the effects of crosswinds. The wind-resistant area and weight of fish-collecting lights tend to be large, and they are susceptible to the effects of crosswinds and shear waves.

  The present invention has been made in view of the above-described disadvantages of the conventional LED fish light, and has an object to provide an LED fish light that is excellent in heat radiation performance and can emit light with high efficiency. I do.

The present invention includes a light emitting unit having one or a plurality of LED light sources, a power supply unit for turning on the LED light sources, a heat radiating unit for cooling the LED light sources, and a mounting unit that is detachably attached to a fish lamp support. LED fishing light equipped with

  Further, the present invention is characterized in that the light-transmitting convex member is a lens.

  Further, the invention is characterized in that the light-transmitting convex member is a cover.

  According to the LED fishlight according to the present invention, since the back radiation fins are provided on the back side of the light emitting unit having one or more LED light sources and the side radiation fins are provided on both side surfaces of the light emitting unit, The heat can be efficiently dissipated, and the intrinsic ability of the LED can be emitted at the maximum value.

  In addition, since a single translucent convex member that covers all the LED light sources and protrudes forward is provided on the front of the light emitting unit, the wind hitting the front of the light emitting unit smoothly enters the ventilation path of the side radiating fins with little resistance. Can be led to the back radiating fins, reducing the wind pressure on the front of the light emitting unit, and at the same time, promoting heat exchange by the back radiating fins on the back of the light emitting unit, which generates a lot of heat, and improving the heat radiation performance. it can.

  Therefore, the LED fish light according to the present invention can be configured with a high output and compact without the disadvantage that it has to be enlarged for heat dissipation unlike the conventional product, and the wind-proof area and the weight of the appliance of the fish light can be reduced. / The total luminous flux can be kept small, and the risk of swaying and falling of the ship when receiving a crosswind or a transverse wave can be greatly reduced.

"First embodiment"
As shown in FIGS. 1 to 4, the LED fish light 10 of the first embodiment includes a light emitting section 1 having an LED light source 11, a power supply section 2 for turning on the LED light source 11, and a heat radiating section for air cooling the LED light source 11. 3 and a mounting portion 4 that is detachable from the support 5.

  The light emitting unit 1 includes a first LED light source that emits visible light of a small fish or plankton to be a prey of a target fish species, and a second LED light source that emits visible light of the target fish species. It is provided integrally on the substrate. The light emitting unit 1 of the present embodiment has a power consumption of less than 100 W, the first LED light source emits light uniformly at a wavelength around the peak of 565 nm, and the second LED light source is squid visible light. It emits light having a peak wavelength of 480 nm.

  Further, the light emitting section 1 of the present embodiment includes a lens 12 protruding at the front thereof. That is, in the present embodiment, the lens 12 is provided as a single translucent convex member that protrudes forward while covering all the LED light sources 11 in front of the light emitting unit 1.

  As shown in FIG. 4, the power supply unit 2 includes an AC / DC conversion power supply 22, and is provided separately from the light emitting unit 1 via a power supply line 21.

  The heat radiating unit 3 includes a rear heat radiating fin 31 provided on a rear surface of the light emitting unit 1 and side heat radiating fins 32 provided on both right and left sides of the light emitting unit 1. Each of the side radiating fins 32 forms a ventilation path 33 that allows ventilation from the front side to the back side of the light emitting unit 1.

  The mounting portion 4 includes a columnar projection 41 and an umbrella-shaped projection having a flange 42 formed on the tip side of the projection 41, and the reinforcing frame 43 to which the tip of the side surface heat radiation fin 32 is connected. It protrudes outward on the side.

  As described above, the fish-collecting lamp 10 of the present embodiment has the rear radiating fins 31 provided on the back of the light emitting unit 1, and the side heat radiating fins 31 integrally formed on both sides of the light emitting unit 1 so as to be partially connected to the rear radiating fin 31. Since the fins 32 are provided and the heat generated from the substrate of the LED light source 11 can be efficiently dissipated into the atmosphere, the inherent ability of the LED can be turned on at the maximum value, and the luminous efficiency = total light emission Since the luminous flux / power consumption is improved compared to conventional products, the metal halide, which is said to have the highest luminous efficiency at present, is 5350 lm / 60 W for blue and white light emitting devices and 138 lm / W for 8300 lm / 60 W for white light emitting devices. The emission efficiency of the lamp is reduced to 130 lm / W.

  Also, the fish collecting lamp 10 of the present embodiment is provided with the side radiating fins 32 on both side surfaces of the light emitting unit 1 so as to form a ventilation path 33 for ventilating from the front side to the back side of the light emitting unit 1. As shown in FIG. 5, the wind hitting the front of the light emitting unit 1 can be guided to the ventilation path 33, and the heat radiation effect by the side heat radiation fins 32 can be enhanced.

  Moreover, the fish-collecting lamp 10 of the present embodiment is provided with the lens 12 which is a single translucent convex member that covers all the LED light sources 11 and protrudes forward in the front of the light emitting unit 1. The wind can be smoothly guided from the ventilation path 33 formed by the side heat radiation fins 32 to the rear heat radiation fins 31 with less resistance, and the heat radiation effect by the rear heat radiation fins 31 can be enhanced.

  In conventional fish-collecting lights, due to the mechanism of the multiple light sources, even if it is a single light source, the luminous protection surface first generates pressure pressure on the surface when the wind hits the device, and the back surface is also complicated. The suction force acts due to the wind involved, and a combined force of both acts is generated in the instrument. However, the fishing light 10 of the present embodiment has a large single spherical lens covering all the LED light sources 11 in front of the light emitting section 1. As shown in FIG. 5, the wind hitting the front of the light emitting unit 1 naturally flows so as to be divided into both sides and easily flows into the back without swirling as shown in FIG. Can also be reduced. This is evident from the shape factor used for wind pressure calculation in the Building Standards Law.

  On the other hand, when the light-transmitting convex member is not provided on the front of the light emitting unit 1 as in the comparative example shown in FIG. 6, the wind hitting the front of the light emitting unit 1 partially stays near the front center. As a result, the flow velocity of the airflow flowing into the ventilation path 33 of the side radiating fins 32 decreases, and the direction of the airflow approaches a direction parallel to the front of the light emitting unit 1. As a result, the flow rate of the airflow passing through the ventilation path 33 and wrapping around the rear heat radiation fins 31 is also reduced, and the heat radiation effect of the rear heat radiation fins 31 is greatly reduced.

  As described above, the fish collecting lamp 10 of the present embodiment is provided with a single translucent convex member that covers all the LED light sources 11 and protrudes forward at the front of the light emitting unit 1 without complicating the structure. By adopting a very simple configuration, the wind pressure on the front of the light emitting unit 1 is reduced, and at the same time, the heat exchange by the back radiation fins 31 on the back of the light emitting unit 1 that generates much heat is promoted.

  In addition, since the fish-collecting lamp 10 of the present embodiment has excellent heat radiation performance, it is possible to configure a high-power and compact structure instead of increasing the size of one lamp as in a conventional product, and to reduce the weight of the instrument / total luminous flux. Since the amount can be kept light, it can be said that it is the optimal direction for light ships that want to reduce the risk of shaking and falling when receiving a shear wave.

  The fishing light 10 of the present embodiment is not a multi-LED light emitting type using two or more LEDs, which is common in conventional products, but a small single board of 100 W or less in which a power source is separately installed at the lower part of a ship. Light emitting type, which is directly fixed to the housing with the radiating fins to greatly improve the heat radiation effect. It can be larger, and even if installed at a high position, it is possible to lower the position of the fish collection light, the power supply, and the total center of gravity of the ship compared to conventional products, so that the ship's roll against the shear wave is reduced and the risk is reduced. Things are possible.

  Further, the fish collecting lamp 10 of the present embodiment is reduced in size for the same reason as described above and the radiation fins are provided directly connected to the rear part of the light emitting unit housing and the left and right sides thereof, so that the index of the maximum light quantity / found area is also a conventional product. By providing a windshield lens that protects the LED on the light-emitting surface of the LED luminous body so as to protrude greatly, the horizontal wind against the ship, in other words, the wind pressure that is blown from the front direction to the present invention is passed vertically and horizontally. This makes it possible to further increase the above-mentioned substantial index, and to reduce the overturning moment of the ship due to the wind.

  In addition, the fish collecting light 10 of the present embodiment includes a first LED light source that irradiates visible light of a small fish or plankton to be preyed on a target fish species, and a second LED that irradiates visible light of the target fish species. Since it is provided with a light source, it emits a wavelength necessary for the fish to be captured and its food chain, and an environment for efficient fish collection can be constructed.

  With the conventional LED fishlight, the target product was the high brightness of the metal halide, so it simply aimed at high output. In the laboratory, for example, a search has been made for the behavior of a squid against light, and a patent based thereon has been proposed. However, it was shown from ecology that the squid responded to the blue system, and since the squid acted at night only for predation, according to the inventors' observations at sea, the squid was blue depending on the species. He seems to be seeing an object in any of the wavelength bands of light 471 nm, 484 nm, and 501 nm, but if the food chain is not formed there, that is, if there is no such thing as his own food, the self It is thought that he will try to leave the place for the protection of his. For this reason, it is considered that a small fish that becomes a bait for squid and a zooplankton that prey on it cannot be used as a fishing light for anglers unless it is collected. I think that is the reason why she is said to be unable to catch much.

  The light-emitting portion of the fish-collecting light 10 of the present embodiment includes a first LED light source that uniformly emits a visible light of a small fish or plankton of a target fish species to be captured and a wavelength around a peak 565 nm, and the above-mentioned fish to be captured. If the target is a species, for example, a squid, a second LED light source that emits visible light with a peak of 480 nm is provided on a single LED substrate, and the animal whose first LED light source has those wavelengths in the visible region is provided. By collecting sexual plankton and small fish as bait for the fish to be captured, the second LED light source allows the fish to be captured to visually recognize it as an image. This gives the angler the opportunity to lift for a long time.

  Further, in the LED fish light 10 of the present embodiment, since the mounting portion 4 is provided on the reinforcing frame 43 to which the tips of the plurality of side surface heat radiation fins 32 are connected, as shown in FIGS. Can be easily attached to and detached from the fishing light support 5 provided on the hull.

  Since it is very difficult to replace the LED with a large LED according to the species of fish to be captured, in other words, it is very difficult to replace the LED, many existing products tended to be instruments with comprehensive wavelengths. From a point of view, it consumes unnecessary energy for catching the target fish species, so it can be said that the method was uneconomical.

  In the present invention, in order to solve this problem, the apparatus is made compact as described above. However, as shown in FIG. A different inverted L-shaped upper groove 51 and lower groove 52 are provided, and first, as shown in FIG. 7A, the upper mounting portion 4A of the LED fish light 10 is first dropped halfway into the upper groove 51, and then the next. When the lower mounting portion 4B matches the lower groove 52, the mounting portion 4B is also dropped into the lower groove 52 as it is, so that the LED fish light 10 of the present embodiment can be mounted on the support 5.

  According to this mounting structure, as shown in FIG. 7 (b), even if the LED fish light 10 is simply pushed up from below by some force F, the upper mounting portion 4A is not disengaged from the upper groove 51. It is highly unlikely that the fish-collecting light 10 itself will fall off and fall, and as in the case where the fish-collecting light 10 is inserted, the lower mounting portion 4B must be shifted sideways by a person's hand and removed from the lower groove 52 to remove the upper mounting portion 4A. Since the lamp cannot be removed from the upper groove 51, it is considered that almost no lamp is detached alone due to wind pressure or swaying of the ship.

  Conventional fish collection lights require specialist skills for installation and replacement due to their size, weight, and complexity of the installation part, so they have to be versatile to send many fish species to one type of equipment. It needed to be incorporated. In other words, this is the flipside of the fact that it is difficult to construct a fish collection environment specializing in the seasonal fish species in the season, so the present invention has a mechanism that fishermen and ship owners can easily replace LED lighting equipment. . If the target fish changes due to seasonal changes or the lifting of the ban, switching to the most suitable lighting equipment for that fish species will enable highly efficient fishing. In addition, since this function can also respond to lamp failure etc. in a short time, in the case of lamp failure as in the past, there is no need to give up fishing and call at the port, leaving other equipment turned on at sea However, it is possible to deal with it, and it is possible to reduce the total loss.
