Description

  The present invention relates to an electric float for fishing that uses an optical fiber for a top serving as a sign and irradiates light from a built-in light source to improve the visibility of the top.

  An electric float for fishing using an optical fiber on the top is provided with a scratched part on the top surface, and when light is emitted from the light emitting diode as a light source to the top end face of the top, light leaks from the scratched part and emits light. It is something that uses that. By providing a plurality of scratch portions, light can be emitted in multiple stages. At this time, the scratch portion near the light emitting diode has a large amount of light, so the scratch is shallow, and the scratch portion far from the light emitting diode has a small amount of light, so the scratch is deep, and the amount of light emitted from the scratch portion is made uniform (for example, Patent Document 1). Because it uses multi-stage light emission, it can detect delicate fish hits even at night, and is loved as a float for fishing times when the fish hits are very awkward or when the watchfulness of Chinu is strong.

In addition, a colored paint such as red or yellow is applied to the scratched part to emit colored light to improve visibility, and further, yellow and red are emitted using a yellow light emitting diode. Has been proposed (for example, Patent Document 2).
JP 60-129709 A JP 2000-41552 A

  However, since the light emitting diode emits light at a single wavelength, if the light emitting diode is a red light emitting diode, a sufficient amount of light can be obtained if the coating color applied to the top scratched part is red, but the other color paint In this case, the amount of light emission is extremely low, or light is emitted with a color synthesized with the color of the paint. Moreover, even if it is attempted to emit yellow and red colors from the top using a yellow light emitting diode, only light emission of a color within the wavelength range of the light emission spectrum of the light emitting diode serving as a light source can be obtained. Only light emission with a color close to orange can be obtained.

  The present invention includes multicolor wavelength components in the emission spectrum, such as a white diode in which a blue light emitting element is covered with a yellow phosphor and a multi-terminal white diode in which a light emitting element of three primary colors of red, green, and blue is mounted. An object of the present invention is to provide a floating element that can emit light of multiple colors in multiple stages from the top using a light emitting diode.

  However, although these white light emitting diodes include multicolored wavelength components in the emission spectrum, the spectrum intensity differs depending on the wavelength, and the emission intensity for each color may vary. In addition, the driving voltage for causing the white light emitting diode to emit light is 3V to 3.7V, and the pin-type lithium battery widely used for electric floats is 3V. Therefore, the voltage of one lithium battery is insufficient. It is. Moreover, in the light emitting diode which mounts the light emitting element of three primary colors, since a several light emitting element is light-emitted simultaneously, it is preferable to use several in parallel also from the point of battery capacity. For this reason, it is necessary to connect and use a plurality of lithium batteries in series or in parallel. In addition, white diodes require further consideration for electrostatic breakdown as compared with conventional red light emitting diodes, yellow light emitting diodes, and green light emitting diodes.

  An object of the present invention is to provide an electric float capable of uniformly obtaining multi-colored light emission in multiple stages from the top, using a light-emitting diode that includes multi-colored wavelength components in an emission spectrum.

  In order to solve the above-described problems, an electric float of the present invention includes an upper case including a battery, a battery holding unit that holds the battery, and a light emitting diode including a multicolored light wavelength component that serves as a light source. A main body composed of a lower case fitted so as to maintain a top, and a top made of an optical fiber disposed so as to guide light from the light source and extend upward from the main body, The scratches are provided with a plurality of scratched portions coated with a colored paint on the surface thereof, and the depth and density of the scratches are adjusted according to the color of the colored paint.

  In this electric float, depending on the color of the colored paint applied to the scratched part, the spectral intensity of each color of the emission spectrum of the light emitting diode and the distance from the light emitting diode to the scratched part are considered, and the depth and density of the scratched part of the scratched part are determined. Since it is increased or decreased, the light emission level from the scratch portion can be made uniform regardless of the color.

  The battery holding portion for holding the pin-type lithium battery has a round hole provided with a belt-like groove on the inner surface, a small hole that is coaxially connected to the round hole, and a contact penetrating to the top following the groove. A housing part having a plurality of battery insertion parts provided with a hole for one piece and a protrusion for hooking a contact piece is provided, and the upper part thereof has a pin hole provided in alignment with the small hole and various wiring holes. A printed wiring board for electrically connecting the battery and the light emitting diode is integrated and disposed, and the groove is formed with a "<"-shaped plus contact portion at the center and a U-shape at the lower end. A folded back hook piece, a wide protruding piece at the upper end, and a conductive plus contact piece having a board insertion portion at its tip and elastically deforming, and the hook insertion piece hooked at the lower end of the groove, and the board insertion portion And through the wiring hole through the contact piece hole The projecting piece portion is disposed so as to be sandwiched and held between the contact piece hooking projection portion and the printed wiring board. A negative contact portion having a "<" shape at one end and a strip-shaped piece at the other end and elastically deforming, and the negative contact portion is coaxial with the small hole. The pin-shaped piece penetrates the pin hole and is arranged so as to penetrate the wiring hole, and the wiring pattern of the printed circuit board, the terminal of the light emitting diode, the plus contact piece, and the minus contact piece Constructed by electrical connection.

  Accordingly, a plurality of lithium batteries can be used so that a driving voltage and a battery capacity sufficient to cause the light emitting diode to emit light can be obtained. That is, the series-parallel connection of the batteries according to the specification of the light emitting diode or the connection with the multi-terminal light emitting diode can be easily performed by designing the wiring pattern of the printed wiring board. Also, the positive contact piece has its protruding piece held between the printed wiring board and the housing part, and the negative contact piece is also held between the printed wiring board and the case part, so when inserting or removing the battery or mounting the battery Even if stress is applied to the plus contact piece and the minus contact piece in the state, the stress does not reach the connecting portion between the plus contact piece and the printed wiring board and the connecting portion between the minus contact piece and the printed wiring.

  In addition, the wiring pattern of the printed circuit board is formed of copper foil, and the gap between the copper foils connected to the plus contact piece is connected to the plus contact piece and the copper foil connected to the minus contact piece. Because it is narrower than the gap between and the positive contact piece close to the outer surface that is susceptible to electrostatic lightning, even if it is exposed to the electrostatic lightning, there is a concern that static electricity will flow through the light emitting diode and destroy the light emitting diode. Less is.

Thus, using a light emitting diode that includes multicolor wavelength components in the emission spectrum, depending on the color of the colored paint applied to the top scratches, the spectral intensity of each color of the emission spectrum of the light emitting diode and the light emitting diode Considering the distance to the scratched part, the depth and density of the scratched part are increased or decreased, so that the light emission level from the scratched part can be made uniform regardless of the color, or for a specific favorite color Can illuminate multicolored light freely, for example by improving the light emission level compared to other colors.

  The top luminescent color is color-coded, making it easy to detect subtle changes in fish that have been difficult to understand at night, just as in the daytime. Furthermore, since the same color as the paint color can be obtained, the paint color that can be seen in the daytime is the same as the light emission color at night, and the visible color from the evening eye to the night does not change. It can be used without any waste, and you can expect fishing results without wasting time at precious time.

  In addition, it has a battery holder structure that can mount multiple pin-type lithium batteries, and in order to perform wiring with a wiring pattern on a printed wiring board, a sufficient voltage is supplied even if the operating voltage of the light-emitting diode is high due to the series connection of the batteries. In addition, it is easy to combine a plurality of batteries and wire them to a multi-terminal light emitting diode to emit light. Furthermore, the connection of the plus contact piece and the minus contact piece to the printed broken line board is performed by sandwiching between the printed wiring board and the housing component and performing mechanical holding, and then connecting by soldering etc. Since the stress on the contact piece generated when the battery is mounted does not affect the connection part, even if the battery is repeatedly inserted and removed, there is no deterioration of the connection part and poor conduction due to breakage, and a highly reliable product can be provided.

  Further, the copper foil wiring of the printed wiring board is configured such that the gap of the copper foil connected to the positive contact piece of the battery is made narrower than the gap between other different poles to prevent electrostatic breakdown of the light emitting diode. For example, when the battery is replaced, if the upper case and the lower case of the main body are removed and touched with a charged hand, static electricity enters one of the positive contact pieces. Therefore, if the other positive contact piece is grounded, the copper foil connected to the positive contact piece narrows the gap, so that static electricity is discharged at this part and falls to the other grounded positive contact piece. . For this reason, it is reduced that the white light-emitting diode that is weak against static electricity is damaged by static electricity, and reliability is increased.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  Fig.1 (a) is an external view of the electric float concerning one Example of this invention, FIG.1 (b) shows front sectional drawing of the electric float. A top 1 made of a plastic optical fiber such as an acrylic resin passes through a cap 6 made of an elastic body such as rubber, and is fixed to an upper case 7 made of a plastic such as ABS resin. The white light emitting diode 2 is electrically connected to the printed wiring board and fixed to the battery holding unit 3. The head of the white light emitting diode 2 is brought close to the lower end face 1d of the top 1. A male screw is provided on the lower outer surface of the upper case 7, and the battery holding part 3 is fixed therein. The lower case 8 made of plastic such as ABS resin has a female screw in the upper opening and is screwed so that an O-ring is sandwiched between the male screw of the upper case 7, and the lower end is fixed with a foot 9 to the end of fishing. A salcan 10 is provided to be attached to the device thread. The top 1 is provided with three scratched portions in which a coating is applied to the outer surface after scratching. From the top, a red flaw portion 1a, a green flaw portion 1b, and a lower portion are a yellow flaw portion 1c. Between each color, 1z is applied in black. In addition, since the order of the colors varies depending on the person, it is preferable to use a favorite color scheme.

FIG. 2 is an enlarged cross-sectional view of the flaw portions 1a, 1b and 1c where the paint 21 is applied to the top 1 surface. A paint 21 is applied. The scratch may be a spot or a circumferential groove. The scratch 1x changes the depth and density depending on the color of the coating material 21 to be applied and the distance from the light emitting diode 2, and adjusts the light emission level from the scratch portions 1a, 1b, and 1c. An example of the emission spectrum of the white light emitting diode 2 is shown in FIG. From FIG. 3, it can be seen that red light having a long wavelength has a low light emission intensity and a high light emission level from blue to green having a short wavelength. Therefore, in the color scheme of the paint 21 as described above, the light emission level of the light emitting diode 2 is low because the red color is in the flawed portion 1a, so that the flaw 1x has a density increased by increasing the depth x or decreasing the pitch y. The flawed portion 1a is located at the tip and away from the white light emitting diode 2, so that the flawed portion 1a can be easily emitted by increasing the depth or increasing the amount. In the next second flaw portion 1b, since the green light emission intensity of the light emitting diode is approximately twice that of red, the flaw 1x has a depth or density half that of red, and the white light emitting diode 2 Is closer than the red flawed portion 1a at the tip, so the depth or density is further reduced. Next, in the third flaw portion 1c, yellow is made shallower because the light emission intensity of the light emitting diode is stronger than that of green, and the flaw 1x is made shallowest, and the distance from the white light emitting diode is also made closest. In this way, the same light emission color as that of the paint applied to the top flaw portion by the white light emitting diode can be obtained, and the light emission level from the flaw portion can be made uniform by adjusting the depth or density of the flaw 1x. In addition, it is possible to devise a technique such as raising the light emission level of a scratch portion of a specific favorite color as compared with a scratch portion of another color.

  4A and 4B show the battery holding portion 3, wherein FIG. 4A is a plan view, FIG. 4B is a front sectional view taken along the line XX, FIG. 4C is a bottom view, and FIG. It is. The outer peripheral surface of the cylindrical casing part 11 is inserted into the lower end opening of the upper case 7 and fixed by adhesion. The battery 4 is inserted into the round hole portion 11a, and the top surface thereof forms a small hole 11b through which the pin terminal 4a of the battery is penetrated. The pair of round holes 11a and the small hole 11b are already positioned at a rotational direction position of 180 degrees. A pair (11a ′, 11b ′) is provided. On the inner peripheral surface of the round hole 11a, a belt-like groove 11d is provided so as to dispose a plus contact piece, which will be described later, and a contact piece hole 11f and a contact piece hooking projection leading to the upper part following the groove 11d. 11e is provided. Further, two bosses 11c are provided on the upper surface of the casing component 11, and a disk-shaped printed wiring board 12 having holes corresponding to the bosses is fitted into the casing component 11, and the bosses 11c are caulked and integrated.

  As shown in FIG. 5, the plus contact piece 13 is formed of a thin belt-like elastic body (for example, a stainless steel plate) having a “<”-shaped plus contact portion 13 a at the center, and the round hole portion of the casing component 11. It arrange | positions at the strip | belt-shaped groove | channel 11d formed in the inner surface of 11a. At this time, the upper portion of the plus contact piece 13 has a wide protruding portion 13b, and this protruding portion 13b is inserted into the contact piece hole 11f following the upper portion of the belt-like groove 11d of the housing part 11 and is inserted into the contact piece hooking protrusion 11e. It will be caught by and will be prevented from coming down. Moreover, the narrow board insertion part 13c penetrates the wiring hole of the printed wiring board 12, and the front-end | tip of the protrusion 13b is connected by soldering. The lowermost end is held on the wall side of the belt-like groove 11d so as to be hooked on the lower part of the belt-like groove 11d of the housing part by the U-shaped folded hook 13d. In this manner, the protrusion 13b is sandwiched between the printed wiring board 12 and the contact piece hooking protrusion, and the plus contact piece 13 is held.

  When the pin-type lithium battery 4 is inserted here, the “<” shape portion 13 a of the positive contact piece 13 is pressed against the wall side of the belt-like groove 11 d, and the “<” shape positive contact portion 13 a tries to straighten. It grows. However, since the upper part is fixed as described above, the U-shaped folded hook 13d of the contact piece 13 moves downward. Therefore, no stress is applied to the soldered portion of the upper tip 13c of the contact piece 13. In addition, the plus contact piece has another one of the same shape in the portion positioned in the 180 ° rotation direction, and correspondingly there are two places on the housing parts, and the reference numerals are given dashes for convenience. .

Further, the minus contact piece 14 shown in FIG. 6 is formed of a thin belt-like elastic body (for example, a stainless steel plate), and has a substantially “U” shape with both ends bent upward, and one end is the battery 4. A narrow belt-shaped negative contact portion 14a in contact with the pin terminal 4a is provided, protrudes upward through the pin hole of the printed wiring board, and the other end is a narrow strip. 14b similarly penetrates the wiring hole of the printed wiring board and is connected by soldering. The central portion 14c is sandwiched between the printed wiring board 12 and the housing component 11 and is mechanically held.

  When the pin-type lithium battery 4 is inserted into the round hole portion 11a, the stress is negative even if the "-"-shaped negative contact portion 14a of the negative contact piece 14 is pushed outward by the battery pin terminal 4a. The structure is such that only the contact portion 14a remains and no stress is applied to the soldered portion of the strip 14b at the other end. Since two minus contact pieces 14 are used in the same manner as the plus contact piece 13, one symbol is given a dash in the drawing.

  FIG. 7 is a circuit diagram of the present embodiment, and two batteries and a white light emitting diode constitute a series circuit. In the structure described above, when the lower case 8 is removed when the battery is mounted, the hook piece 13d below the plus contact piece 13 is near the outer surface and may be touched. When the hook 13d under the positive contact piece 13 is touched in a static state and the hook 13d 'under the other positive contact piece 13' is grounded under some influence, the light emitting diode It is assumed that static electricity will break down. In the circuit diagram of FIG. 7, if static electricity falls to the positive contact piece 13 ′ side of the right battery, the static electricity jumps to the positive contact piece 13 on the left from the negative side 14 of the same potential next to the positive contact piece 13 ′. It is conceivable that the circuit escapes from the portion and the negative contact piece 14 'on the right side, flows from the negative side of the white light emitting diode 2 to the positive side, and connects to the positive contact piece 13 on the left side to escape. In the latter case, static electricity is destroyed because it passes through the light emitting diode. Therefore, if the gap g (see the plan view (a) in FIG. 4) of the wiring pattern on the printed circuit board wiring connected to the two positive contact pieces is made smaller than the gap between the other different polarities, either positive contact piece will become static. Even if splatters, it chooses a part with a small gap in the copper foil, so it falls to the positive contact piece without passing through the white light emitting diode 2, so that there is no risk of damage due to static electricity.

  It is mainly used as an electric float for night fishing.
