Description

Flashlight {FLASHLIGHT}

The present invention relates to a flashlight, and more specifically, an incandescent light bulb or a multi-color LED is turned on so that the light can be irradiated according to the purpose of use, and the residual current is filled in a supercapacitor of an appropriate capacity. In addition to instant lighting in an emergency, and if both hands must be used for self-powered flashlight to irradiate the color of light for the purpose of use without the need for hand movement for power generation.

In general, a flashlight is an emergency equipment used for various purposes such as lighting a desired place and object outdoors or indoors by a light bulb that is powered by a battery, or lighting for an emergency such as a power outage, emergency indicator, and traffic police. It is a necessity of life.

However, the flashlight must always be provided with a battery, and since the discharged battery must be replaced at any time, there is an economic burden due to the purchase of the battery, and there is a hassle of periodic replacement.

In order to solve this disadvantage, a self-powered flashlight using a current generated by inducing a magnetic field to a coil has been proposed.

Self-powered flashlights are usually configured to generate a current in the induction coil by rotating the magnet when the lever is pulled. However, in the case of releasing the lever, the induced current does not occur, so it is inconvenient to frequently repeat the operation of squeezing and releasing the lever, and the mechanical noise is increased.

A method for solving the disadvantages of the power generation method of the self-powered flashlight has been proposed.

Examples of improvement proposals for self-powered flashlights include Korean Utility Model Publication No. 1999-22605 (Flashlight) and Korean Utility Model Publication No. 1999-33610 (Flashlight).

Korean Patent Application Publication No. 1999-22605, which is an electronic device, is designed to store a battery in a self-powered flashlight and use the battery and the current generated by self-power generation. When discharged, it uses the current generated by self-power generation.

However, this design is not a fundamental solution to solve the shortcomings of the power generation method, but rather the disadvantage that the volume and weight of the flashlight is increased by the battery is housed.

The latter, Korean Laid-Open Utility Model Publication No. 1999-33610, the rack is connected to the lever via a pivot means and formed in a substantially depressed shape while the front and rear gear parts are formed on opposite sides, respectively, and end portions are formed at both ends; It is installed between the gear portion of the rack and is connected to the magnet through the gear train is configured to include a pinion for rotating the magnet.

According to this, when the lever is pulled, the pinion is engaged with the forward gear part of the rack, and if the lever is released, the pinion is engaged with the backward gear part of the rack so that the pinion is rotated in the same direction when both the lever and the lever are released.

According to Korean Utility Model Publication No. 1999-33610, the problem of the power generation method by rotation is solved, but the following problems occur.

As the rack is moved laterally by the pivot means, the forward gear portion or the reverse gear portion is configured to be engaged with the pinion. The pinion may not rotate normally due to the deformation due to the production error and wear of the pivot means. The magnet may not rotate as well. On the other hand, high precision machining is required to solve this problem, there is a disadvantage that the productivity is low.

When the lever is completely grasped or fully released, the pinion is placed at the end of the rack formed at both ends of the rack so that the pinion is continuously rotated for a short time without stopping and the power generation is continued without continuously holding and releasing the lever. Infants are weak and unable to pull the lever completely, so its utility is low.

In addition, the generated current is to be charged in the battery for the storage, but the current generated by the rotation of the magnet is an alternating current, and because the storage device including the battery uses a direct current, it is impossible to charge in the state of simply the proposed alternating current. Do.

As such, the self-powered flashlight does not use a battery and has a great economic and environmentally friendly advantage, but it must be continuously supplemented to improve its own structural problems.

However, even under these conditions, the above-described battery-type flashlight or self-powered flashlight provides the necessary light, thereby achieving their main function and purpose of use. However, when you need to use a flashlight in real life, there is a wide variety of outdoor and indoor lighting, objects for finding objects, reading books, taking notes, urgent or emergency signs, and danger lights. In addition, depending on the purpose of use, reading, memo, etc. will require bright light, and if you are looking for an object, you can achieve the purpose even if it is not bright. It is desirable to irradiate colored lights such as red so that it can be seen by the eyes. Especially in case of an emergency emergency light, a special continuous lighting is required.

However, each of the disadvantages of the battery storage type flashlight or self-powered flashlight according to their power generation method can be irradiated for various situations since only one light bulb and one light / color light bulb are used. It does not have a function. Therefore, in order to illuminate a variety of light for this purpose, it is necessary to purchase / carry a number of ordinary flashlights, the cost increases, and is inconvenient to carry and store.

The present invention is designed to solve the problems as described above, to provide light of the appropriate brightness according to the various purposes of use of the flashlight, and to be able to irradiate light of various colors, and also to immediately turn on in an emergency In addition, the purpose is to provide a self-powered flashlight that can be turned on even without mechanical operation from the outside for power supply to be made at the same time.

Phosphor white LED L2 and red LED L3.

Hereinafter, the structure of the flashlight according to the present invention will be described in detail.

As shown in FIG. 1, the case 10 includes a left and right side plate 11 and 12 and a left and right side plate 11 and 12 formed of a symmetrical shape and coupled to each other to form a hollow portion having an open front therein. The head 13 is detachably coupled to the front part. Then, the back of the case 10 is connected to the wrist strap 14 (shown in Figure 2), the back of the locking pin 15 to attach the lever 20 to the case 10 side can be rotated To be combined.

As shown in FIG. 2, the lever 20 is rotatably installed at one end thereof via a hinge pin 21 and a torsion coil spring 22 inside the case 10, and the other end thereof is provided with a case ( While protruding to the outside of 10), a curved rack 23 is formed to extend substantially vertically on one surface thereof, and a bent portion is formed on the rear surface to facilitate gripping.

As shown in FIG. 5, the induction current generating means is rotatably installed on one surface of the plate 30 and the plate 30 fixed to the case 10, while the upper portion is opened in one direction at the peripheral edge thereof. A conductor disc 40 having a rotating body mounting hole 42 in which an inclined ratchet-shaped gear part 41 is imprinted, a magnet 50 coupled to the lower part of the conductor disc 40, and a conductor disc Two-stage drive pinion is composed of an induction coil 51 is installed on the outer portion of the 40, and the upper and lower gears are rotatably installed in the case 10 and meshed with the first 23 pinion 61. (60) (shown in Figure 2), and the fixed shaft 43 installed in the rotating body mounting hole 42 of the conductor disc 40 rotatably coupled and formed in an approximately elliptical shape at both ends of its long sides. A shaft pin 71 is formed and driven pinion 72 engaged with the second pinion 62 of the drive pinion 60 turns upward. Rotating guides 80 which are rotatably coupled to the formed rotating body 70 and the shaft grooves 71 of the rotating body 70 and forcibly rotating the conductor disc 40 according to the manipulation of the lever 20. It consists of.

The induction current generating means will be described in more detail.

As shown in FIGS. 5 and 6, the rotating body 70 in which the rotary guide 80 is inserted into the shaft groove 71 (shown in FIG. 5) is fixed to the fixed shaft 43 of the conductor disc 40. The rotary guide 80 is inserted such that its free end faces the valley 41a of the ratchet gear portion 41.

Rotation guide 80 which is rotatably installed in the shaft groove 71 of the rotor 70 via the shaft 81 has both the conductor disc 40 in the same direction when the lever 20 is removed and placed. Let it rotate

When the lever 20 is gripped, the rotation guide 80 is rotated together with the rotation body 70, and the free end of the rotation guide 80 is valleys 41a of the ratchet-shaped gear part 41 of the conductor disc 40. ) Is rotated forcibly while pushing the conductor disc 40, and, on the contrary, when the lever 20 is released, the rotation guide 80 moves in the opposite direction as when the lever 20 is removed together with the rotor 70. The conductive disc 40, which is rotated but rotated by inertia, because the free end, which is inserted into the valley 41a of the ratchet gear 41, passes over the inclined portion 41 b of the ratchet gear 41. It does not restrict the rotation of the.

The bottom of the case 10 is provided with a mobile phone emergency power supply jack (J) that can be connected to the mobile phone charging plug (P).

The DC current rectified by the rectifier 1 and stored in the supercapacitor 2 is applied to the light emitting members L2 and L3 made of LEDs or the mobile phone emergency power supply jack J by the second changeover switch 4. .

1 and 2, the light emitting member (L) of the flashlight 100 according to the present invention is an incandescent bulb (L1), and the white LED is arranged up and down symmetrically around the incandescent bulb (L1). It consists of (L2) and red LED (L3).

LED (L2) (L3) is not limited to this may be arranged symmetrically around the incandescent bulb (L1), as shown in Figure 4, a plurality of alternating arrangement along the circumference of the incandescent bulb (L1) Can be.

The incandescent lamp L1, the white LED L2 and the red LED L3 are selectively turned on / off by the operation of the changeover switch 3,4.

LED has the advantage that the duration of lighting is longer than incandescent bulbs by one operation to hold the lever 20 because the power consumption is small while maintaining sufficient brightness.

Referring to the operating state of the flashlight according to the present invention configured as described above are as follows.

As shown in FIG. 7A, when the lever 20 is grasped, the lever 20 is rotated about the hinge pin 21 (shown in FIG. 2) into the case 10 (shown in FIG. 2). The rack 23 is inserted into a linear motion, and the drive pinion 60 is rotated in the clockwise direction based on the drawings by the linear motion of the rack 23.

As the driven pinion 72 engaged with the second pinion 62 of the drive pinion 60 rotates, the rotor 70 mounts the rotor mounting hole of the conductor disc 40 about the fixed shaft 43. 42) Rotate counterclockwise inside.

When the rotating body 70 is rotated, the rotation guide 80 is rotated toward the ratchet gear 41 by the centrifugal force toward the ratchet gear 41, and its free end of the ratchet gear 41 is rotated. Inserted into the valley 41a, the inclination of the front of the valley 41a is very urgent so that the rotation guide 80 is rotated counterclockwise while pushing the conductor disc 40 without falling out of the valley 41a.

As shown in FIG. 6, the magnet 50 is rotated together with the conductor disc 40 to generate a magnetic field, and the magnetic field is induced by the induction coil 51 to generate an alternating current in the induction coil 51.

As shown in FIG. 2, the alternating current generated in the induction coil 51 is applied to the incandescent lamp by the operation of the first changeover switch 3, or is converted to direct current through the rectifier 1 so that the supercapacitor 2 ) Is stored.

As described above, induction current is generated while holding the lever 20, and the flashlight according to the present invention, even when the lever 20 is held, the magnet is rotated in the same direction by inertia, so that the induced current is generated without a break. Characterized in that can be.

That is, when the lever 20 held by the lever 20 is released, the lever 20 protrudes out of its original position, that is, outside the case 10 by the restoring force of the torsion coil spring 22 (shown in FIG. 2), and the lever 20 As the protrusion protrudes, the rack 23 linearly moves in the reverse direction, and the driving pinion 60 rotates counterclockwise.

The rotating body 70 is rotated clockwise by the drive pinion 60 so that the rotating guide 80 also rotates clockwise. In this case, the rotating guide 80 is a ratchet type of the original disc 40. The inclination part 41b of the gear part 41 is crossed, and the conductor disc 40 is continuously rotated by the inertia in the immediately moving direction (counterclockwise direction which was rotated when the lever 20 was removed).

As the magnet 50 rotates together with the conductor disc 40, an alternating current is generated in the induction coil 51 as in the case of releasing the lever 20. The alternating current is converted to direct current via the rectifier 1.

The current converted to direct current by the rectifier 1 is stored in the supercapacitor and used to turn on the LED, and among the white LED L2 or red LED L3 depending on the purpose of use by the second switching switch 4. Either one can be turned on and the LEDs L2 and L3 are turned off, so that the generated current is efficiently stored in the supercapacitor 2. In this case, in order to have efficiency of lighting and power storage, the supercapacitor 2 should have a suitable size.

For example, when lighting outdoors or taking a simple note, the incandescent lamp L1 is selected. In this case, as shown in FIG. 3, when the first switch 3 is connected to the contact point A, the incandescent lamp L1 is turned on by directly using the AC current generated by the induction current generating means.

On the other hand, when the lighting effect can be obtained even by the light of the intensity irradiated from the LED (L2) (L3), the first changeover switch 3 is connected to the contact B. In this case, the generated alternating current is rectified by the rectifier 1 and stored in the supercapacitor 2, and the white LED L2 or the red LED L3 is selectively lit in accordance with the operation of the second changeover switch 4. Since the LED light emitting members L2 and L3 consume small power, only a part of the generated current is consumed, and the remaining large amount of current is stored in the supercapacitor 2.

When both the white and red LEDs L2 and L3 are turned off by the operation of the second changeover switch 4, the generated current is automatically stored in the supercapacitor 2 efficiently. In case of an unavoidable emergency in which the means cannot be operated, it is used to light up the light emitting member L2 or L3.

In addition, when an emergency occurs, the remote person is notified of his or her emergency situation by the red light emitted from the red LED (L3). In this case, by connecting the first changeover switch 3 to the contact point B, the AC current generated by the induction current generating means is switched from the rectifier 1 to the direct current, and the second changeover switch 4 is connected to the red LED L3. Red light is irradiated from the red LED L3, and at the same time, the residual current is stored in the supercapacitor 2 of a certain capacity.

As described above, the present invention, the lighting of the incandescent bulb (L1) directly uses the generated alternating current without using the stored current, and the lighting of the white LED (L2) and red LED (L3) is incandescent bulb (L1) Contrary to the case of), it uses a circuit that uses the stored current after converting it to direct current instead of directly using alternating current, and also installs a supercapacitor having an appropriate size capacity for power storage. There are several reasons for this.

The first reason is to ensure the function of use in an emergency as the flashlight is an emergency article. In the case of a battery storage flashlight, if the regular battery replacement is not made due to the natural discharge of the battery, the flashlight will not function as an emergency in an emergency. For example, if you use the smallest 0.15A incandescent bulb for flashlight, the capacity of the wall heat bulb is supercapacitor with excellent storage characteristics. Should be. In this case, because the supercapacitor is expensive because of its high capacity, the cost competitiveness is lost when considering the price of a normal flashlight. Aside from this problem, even when the 20F supercapacitor is mounted, the current generated by the high-capacity supercapacitor flows even if the current is generated by operating the induction current generating means to turn on the incandescent lamp of 0.15A. Before the electric current is stored, the incandescent light bulb becomes difficult to be turned on, so that the emergency flashlight does not function. In addition, in order for the 0.15A incandescent lamp to light for 5 minutes, a 20F supercapacitor must be sufficiently stored. In order to achieve such storage, magnets inducing a current enough to illuminate an incandescent lamp of a self-powered flashlight (BH _max = 5.0 to 10 KJ / m ³ , -H _c = 6 to 15 KA / m, B _r = 0.6 In order to achieve a desired power storage as ˜1.2 VS / m ² ), it is possible to operate the induction current generating device for at least 10 minutes while all the light emitting members are turned off. Therefore, lighting the incandescent lamp using the stored DC current has many problems in efficiency.

The second reason is to increase the ease of use. As described above, the lighting of the incandescent lamp which can maintain the highest illuminance is preferably used directly with the induced current generated. However, to do this, the induction current generating means must be continuously operated, and since the hand movement is maintained continuously, it may be necessary to take a short break during the operation, and the noise of the operation may need to be reduced. In this case, the illuminance is relatively lower than that of the incandescent lamp by operating the switching switches 3 and 4, but the white LED L2 lights with charging. In this case, however, the capacity of the supercapacitor installed for charging is preferably less than 2F. If a supercapacitor having a capacity of 2F or more is installed, a supercapacitor having a capacity of 20F is used to turn on the incandescent bulb by the power storage. The same phenomenon as that occurs. In other words, if a switch having a capacity of 2F or more is installed, even if the changeover switch is operated to turn on the LED, the LED cannot be turned on immediately until a certain amount of current is stored in the supercapacitor. In fact, even if a supercapacitor having a capacity of 1F is installed, when the handle of the induction current generating means is operated twice per second for 1 minute even when the LED is on, the highest illuminance that the LED can produce is 10 in the case of the white LED (L2). It is kept for more than a minute and for about 30 minutes in the case of the red LED (L3). The relationship between the capacitance of the supercapacitor and the LED lighting needs to be further considered when the red LED is to be turned on, which can be used especially in an emergency situation. In other words, when a very urgent situation arises over time and a situation where it is difficult to continuously operate an induction current generator with one hand is connected, the circuit configuration and the installation of a supercapacitor having an appropriate capacity must be provided. Element.

On the other hand, when the power storage mode is selected by the mode changeover switch, the alternating current generated from the induction current generating means is converted into a direct current through the rectifier 1 and is stored in the supercapacitor 2, which is used for lighting the LED, It may be applied to the jack J to become an emergency power source of the mobile phone.

The supercapacitor 2 has a very high power storage characteristic compared to a battery so that a high capacity current can be stored in a short time holding the lever 20. The induced current induced in the induction coil 51 is different depending on the number of coils wound and the strength of the permanent magnet. However, if the operation of holding and releasing the lever 20 continues, a current of about 3 to 4 V is sufficiently maintained. It can be used as an emergency power supply for cell phones powered by a voltage of about 3.6V.

When the charging plug P of the cellular phone is plugged into the jack J, a DC current is supplied to the cellular phone battery through the plug P to charge the cellular phone battery.

<Example 2>

8 shows another embodiment of the induction current generating means applied to the flashlight according to the present invention. In the case of Example 2, the flashlight presented in Example 1 rotates the teeth 61 connected to the upper layer of the large cogwheel 60 by the mechanical operation of the lever 20, as shown in FIG. Since the attached rotating disc rotates a lot of force and the use of a large cog wheel, the size of the entire flashlight is increased, so that the operation of the induced current generating means is not easy for women or children with small or weak hands. Example 2 was carried out in view of such a point.

As shown in FIG. 8, the lever 20 and the permanent magnet 50 may be connected via a gear train.

The rack 21 of the lever 20 is connected to the conductor disc 94 via the drive gear 90, the first, second, and third driven gears 91, 92, 93. Inside the second driven gear 92 is made of the same structure as the conductor disc 40 (shown in FIG. 5) of the first embodiment described above is provided with a rotating body 70 therein.

The rack 21 of the lever 20 is engaged with the first pinion 90a of the drive pinion 90, and the second pinion 90b of the drive pinion 90 is the first pinion of the first driven pinion 91. The second driven pinion which is meshed with 91a, the second pinion 91b of the first driven pinion 91 is engaged with the driven pinion 72 of the rotating body 70, and is rotated by the rotating body 70. 92 is engaged with the third driven pinion 93, and the third driven pinion 93 is engaged with the magnet 50. Since the rest of the configuration is the same as in the first embodiment described above, it is omitted.

According to the second embodiment, even when the lever 20 is gripped and released with less force than in the first embodiment, the rotating guide 70 rotates through the driving pinion 90 and the first driven pinion 91. 80 rotates the second driven pinion 92. The third driven pinion 93 is rotated by this rotational force, and as a result, the magnet 50 is rotated. As the magnet 50 is rotated, a magnetic field is generated, and the magnetic field is guided to the induction coil 51 to generate an alternating current in the induction coil 51.

Therefore, when a certain brightness is required at night by operating the light emission color switching switches 3 and 4, the incandescent lamp L1, which maintains the brightness, is turned on, and the luminance is relatively lower than that of the incandescent bulb, but mechanical hand motion is stopped. Even if the lamp is turned on by using the stored current, operate the switch to turn on the white (L2) or red LED (L3).

When the lever 20 is released when the rotation guide 70 forcibly rotating the conductor disc 40 when the lever 20 is released, the conductor disc 40 is not restrained because the rotation guide 70 does not restrain the rotation of the conductor disc 40. ) Is continuously rotated in the same direction as when the lever 20 is removed by the inertia to maintain the state of the immediately preceding movement, so that the induced current is always generated.
