  The lighting fixtures of Patent Documents 1 to 4 are all intended to be used with the lighting fixtures attached to fingers, and there is room for improvement in that the use of the lighting fixtures is limited. In order to prevent unnecessary battery consumption, a switch is provided in the lighting fixture. In many cases, the switch is configured as a change-over switch that opens and closes a current path. Therefore, it is necessary to connect the battery, the LED (or light bulb) and the switch terminal with lead wires, and it is necessary to configure the switch with a plurality of parts, and the overall structure of the lighting fixture becomes complicated. The production cost is increased accordingly.

  An object of the present invention is to provide a lighting apparatus that can simplify the switch mechanism and greatly reduce the overall cost. An object of the present invention is to provide a lighting apparatus that can reliably open and close a current path and blink an LED reliably even though the switch mechanism has a simplified structure. .

  An object of the present invention is that a main body case that houses an LED and a battery can be attached and fixed to a finger, clothes, glasses, etc. as necessary, and the irradiation central axis of the LED can be freely changed and adjusted, so that it is easy to use. To provide an instrument. An object of the present invention is to provide a luminaire that can heat and disinfect a body case, a fixture, and the like, and is therefore advantageous for repeated use in a medical field.

  The lighting fixture of the present invention includes an LED 1 serving as a light source, a battery 2 serving as a power source, a switch piece 3 that opens and closes an energization path between the LED 1 and the battery 2, and a main body case 4 that accommodates these members. ing.

  At least one of the connection leads 6K of the LED 1 is in direct contact with the outer surface of the battery 2 to form an energization path. The switch piece 3 includes a switching piece 33 that separates the connection lead 6K from the battery 2 and holds it in a non-conductive state, and is supported by the main body case 4 so as to be able to reciprocate between an on position and an off position. In a state where the switch piece 3 is switched to the off position, the connection lead 6K is held in a non-conductive state by the switching piece 33.

  Specifically, the switch piece 3 including the operation knob 26 is supported by the main body case 4 so as to be reciprocally rotatable, and one connection lead 6K of the LED 1 is connected to the periphery of the battery case 2a of the battery 2 as shown in FIG. The other connecting lead 6A directly contacts the peripheral surface of the sealing plate 2b of the battery 2. At least the switching piece 33 of the switch piece 3 is formed of an insulating material. Thus, in the state where the switch piece 3 is switched to the OFF position, the switching piece 33 receives the connection lead 6K and holds it in the non-conductive state.

  The switch piece 3 is integrally formed with a battery tray 25 that accommodates the battery 2, and the battery tray 25 includes a circular bottom wall 28 and an arc-shaped peripheral wall that is erected along the periphery of the bottom wall 28. 29 and an operation knob 26 projecting from the outer surface of the peripheral wall 29. A switching piece 33 for separating the connection lead 6K from the battery is formed at the end of the peripheral wall 29, and the center position P2 of the battery 2 accommodated in the battery tray 25 is changed to the rotation center position P1 of the switch piece 3. It is arranged so as to be eccentric. Thus, as the switch piece 3 is operated from the off position to the on position, the battery case 2a can move closer to and contact the corresponding connection lead 6K.

  The main body case 1 is composed of a front case 4A and a rear case 4B that are joined together in a lid-like manner. In FIG. 4, the switch piece 3 is placed between an on position and an off position between the switch piece 3 and the rear case 4B. A click mechanism for holding the position is provided.

  The LED 1 is held immovably by the light emitting bulb 1 a being fitted into the irradiation window 8 provided in the front case 4 </ b> A of the main body case 4. The bottom wall 28 of the battery tray 25 is positioned by a plurality of positioning ribs 14 provided on the inner surface of the front case 4A and a plurality of receiving surfaces 18 provided on the inner surface of the rear case 4B, and is supported so as to be capable of reciprocating rotation. Yes.

  A mounting tool 5 is attached to the main body case 4, and the main body case 4 and the mounting tool 5 can be relatively rotated around an axis that intersects the irradiation center axis of the LED 1 and can be held at any rotational position. It is connected.

  In FIG. 3, the front case 4 </ b> A is integrally formed with a connection boss 11 for the attachment 5, and the attachment 5 is integrally formed with the ring portion 38 and the ring portion 38 and is externally fitted to the connection boss 11. And a mounting ring 39 to be connected. In addition, the engaging surface between the connection boss 11 and the mounting ring 39 is provided with a joint structure for holding the main body case 4 at an arbitrary rotational position.

  The front case 4A, the rear case 4B, and the switch piece 3 can each be formed of a heat-sterilizable polymethylpentene resin.

  In the present invention, the LED 1, the battery 2, the switch piece 3, and the body case 4 that accommodates these members constitute a lighting fixture, and at least one of the connection leads 6 K of the LED 1 is directly connected to the outer surface of the battery 2. The contact leads 6K themselves constitute an energization path. In addition, by separating the connection lead 6K from the battery 2 with the switch piece 3, the current path of the LED 1 can be held in a non-conductive state.

  In other words, the current path of the LED 1 can be opened and closed by bringing the connection lead 6K into contact with the battery 2 or by performing a separation operation. As described above, according to the switch mechanism that uses the connection lead 6K of the LED 1 as a contact terminal of the switch mechanism and performs the switching operation with the switch piece 3, the structure of the entire switch is significantly simplified as compared with the conventional switch mechanism. The overall cost of the fixture can be greatly reduced, and the contact failure, which accounts for most of the failures in the fixture, can be eliminated, improving the reliability of the fixture.

  According to the switch structure in which the switch piece 3 is supported by the body case 4 so as to be capable of reciprocating rotation and the switch piece 3 is switched to the OFF position, the switching piece 33 receives the connection lead 6K and holds it in a non-conductive state. Even when the lighting fixture is dropped on the floor surface and receives a large impact, the switching piece 33 can surely prevent the connection lead 6K from contacting the peripheral surface of the battery case 2a, and the structure is simple. A switch structure with excellent reliability can be obtained. If the connection leads 6A and 6K of the LED 1 are brought into direct contact with the peripheral surface of the sealing plate 2b of the battery 2, the connection lead wire can be omitted, so that the structure of the lighting fixture can be further simplified and the labor required for assembly can be reduced. In addition, the overall cost of the luminaire can be further reduced (claim 2).

  The battery tray 25 is formed integrally with the switch piece 3, and the center position P <b> 2 of the battery 2 accommodated in the battery tray 25 is eccentrically arranged with respect to the rotation center position P <b> 1 of the switch piece 3. According to the switch structure that allows the battery case 2a to move toward and contact the corresponding connection lead 6K during operation, the battery case 2a can be operated even if there is some variation in the position and orientation of the connection lead 6K. 2a and the connection lead 6K can be brought into electrical contact with certainty, and an appropriate conduction state can be obtained. A reliable lighting apparatus capable of reliably flashing the LED is obtained. Further, when the battery tray 25 is integrally formed on the switch piece 3 and the operation knob 26 and the switching piece 33 are provided on the peripheral wall 29, an increase in the number of parts due to the switch structure and the battery tray 25 is prevented. Thus, the lighting apparatus can be provided at a lower cost (claim 3).

  If a click mechanism is provided between the switch piece 3 and the rear case 4B to hold the switch piece 3 in the on position and the off position, the switch piece 3 can be mounted unless there is a clear intention of the user. Since the switching operation cannot be performed, the switch piece 3 is accidentally turned on and the LED 1 is inadvertently turned on, the battery 2 is exhausted unnecessarily, or the switch piece 3 is turned off due to a collision with another object. It is possible to reliably prevent the LED 1 from being turned off (Claim 4).

  The front case 4A and the rear case 4B that are joined together in a lid form form the main body case 1, and the bottom wall 28 of the battery tray 25 includes a plurality of positioning ribs 14 provided on the inner surface of the front case 4A, and the rear case 4B. According to the lighting fixture that is positioned by the plurality of receiving surfaces 18 provided on the inner surface of the LED 1 and is fixedly held immovably by fitting the light emitting bulb 1a of the LED 1 into the irradiation window 8 provided in the front case 4A, the front and rear cases 4A By simply fitting and mounting 4B, the connection lead 6K mounted on the front case 4A and the battery 2 mounted on the rear case 4B come into contact with each other in a properly positioned state. You can do it. In addition, the connection lead 6K and the battery 2 can be properly connected. By supporting the bottom wall 28 of the battery tray 25 with the plurality of positioning ribs 14 and the plurality of receiving surfaces 18, the entire switch piece 3 is supported so as to be capable of reciprocating rotation. Therefore, the rotation center position P 1 of the switch piece 3 is the main body. There is no variation in the inside of the case 4, and the reliability of the switch structure is further improved by that amount.

  According to the luminaire in which the main body case 4 and the fixture 5 attached to the main body case 4 are coupled so as to be relatively rotatable about an axis intersecting the irradiation center axis of the LED 1 and to be able to hold the position at an arbitrary rotational position. Since the necessary part can be illuminated by changing and adjusting the direction of the irradiation center axis of the LED 1 and the position thereof can be maintained, only the necessary part can be intensively illuminated, and the usability of the lighting apparatus can be improved. For example, as shown in FIG. 7, in the case of the fixture 5 for attaching the lighting fixture to the finger, after attaching the fixture 5 to the fingertip, the position of the main body case 4 is simply changed, and the target portion is concentrated by the LED 1. Can be efficiently illuminated with both open hands (claim 6).

  The ring portion 38 and the mounting ring 39 constitute the fixture 5, and the main body at an arbitrary rotational position on the engagement surface between the connecting boss 11 of the front case 4 </ b> A and the mounting ring 39 that is externally connected to the connecting boss 11. When the joint structure that holds the case 4 in position is provided, the main body case 4 that is rotationally displaced around the connecting boss 11 can be held more reliably at the displaced position, and other objects accidentally collide with the main body case 4. Even in such a case, the irradiation direction of the LED 1 can be reliably prevented from shifting.

  If the front case 4A, the rear case 4B, and the switch piece 3 are each formed of heat-sterilizable polymethylpentene resin that is excellent in heat resistance, the main body case 4 can be disinfected by heating. When used, it is possible to prevent secondary infection of other patients due to bacteria or viruses attached to the main body case 4 or the like, and it is suitable for a lighting apparatus that can be used safely and repeatedly in the medical field. .

  1 to 7 show an embodiment of a lighting fixture according to the present invention. In FIG. 1 to FIG. 3, the luminaire is turned on by opening and closing an LED (light emitting diode) 1 serving as a light source, two batteries 2 for supplying driving current to the LED 1, and a current path between the LED 1 and the battery 2. A switch piece 3 that switches between a state and an off state, a main body case 4 that accommodates these members, and a fixture 5 that is attached to the main body case 4 are provided.

  The LED 1 is a high-intensity white LED having a bullet-type light emitting bulb 1a, and has positive and negative connection leads 6A and 6K projecting from the base end thereof. The battery 2 is composed of a button-type lithium battery, and the battery case 2a also serves as a negative output terminal, and the sealing plate 2b serves as a positive output terminal.

  2 and 3, the main body case 4 is configured by joining the front case 4A and the rear case 4B which are divided into front and back in a cover-matching shape, and the planar shape is a shape simulating the cross-sectional shape of the back teeth, It consists of a hollow case with flat upper and lower surfaces. The front case 4A generally forms the root portion of the simulated tooth, and the rear case 4B forms the crown portion.

  The front case 4A is formed of a hollow case that opens backward, and an irradiation window 8 for mounting the LED 1 is opened in a recess in the center of the front portion, and a cylindrical wall that positions and supports the light emitting bulb 1a of the LED 1 on the inner surface thereof. 9 protrudes backward.

  On the inner surface of the opening edge of the front case 4A, a fitting wall 10 that is externally fitted and joined to the rear case 4B is formed, and a connecting boss 11 for the fixture 5 is integrally formed on the lower surface side of the opening edge. . A flange 12 having a partially arcuate peripheral edge is formed on the front and rear ends of the connecting boss 11 to prevent separation of the fixture 5 (see FIG. 3), and the connecting boss 11 faces the center of the base end. Vertical ribs 13 are provided so as to protrude from the peripheral surface of the rim. The function of the vertical rib 13 will be described later. Positioning ribs 14 are provided on the left and right sides of the inner surface of the bottom wall of the front case 4A so as to hold and hold a battery tray 25 described later (see FIGS. 1 and 4).

  The rear case 4B is a hollow case that opens forward. As shown in FIGS. 2 and 4, an operation window 17 for exposing the operation knob 26 of the switch piece 3 is opened at the center of the rear part. A pair of left and right receiving surfaces 18 for positioning and holding the battery tray 25 in cooperation with the positioning ribs 14 are formed on the left and right sides of the inner surface of the opening. On the outer surface of the opening edge of the rear case 4B, a fitting wall 19 that is fitted and joined to the front case 4A is formed.

  The upper and lower fitting walls 10 and 19 of the front case 4A and the rear case 4B are formed with engagement protrusions 20 that engage with each other and hold the cases 4A and 4B in an unseparable manner, and engagement holes 21. Has been. In FIG. 3, the engagement protrusion 20 is formed in the fitting wall 19 of the rear case 4B, and the engagement hole 21 is formed in the fitting wall 10 of the front case 4A. The space between the upper and lower walls of the rear case 4B is the same as or slightly smaller than the vertical height when the two batteries 2 are stacked one above the other, and the sealing plate 2b of the battery 2 and the connecting leads 6A It is for making it contact reliably.

  The switch piece 3 is integrally provided with a battery tray 25 for housing the battery 2, an operation knob 26, and a switching piece 33. The battery tray 25 includes a circular bottom wall 28 and a peripheral wall 29 having an arc shape that is erected along the periphery of the bottom wall 28, and receives the connection lead 6 </ b> A on the positive electrode side of the LED 1 on the bottom wall 28. A drum-shaped recess 30 is formed.

  The operation knob 26 protrudes from the outer surface rear side of the peripheral wall 29. The two batteries 2 are accommodated in a space surrounded by the peripheral wall 29 and the bottom wall 28 in a state where the respective sealing plates 2b face the bottom wall 28, that is, in a serial connection state. In this accommodated state, the peripheral surface of each battery 2 is exposed through an open port 31 formed between the end portions of the peripheral wall 29, and as will be described later, the periphery of the upper battery 2 facing the open port 31. The connection lead 6K on the negative electrode side of the LED 1 contacts the surface.

  Of the peripheral wall 29 facing the previous opening 31, a lower step 32 is formed at the end of the peripheral wall on the lower side in FIG. 4 (see FIG. 3). A wedge-shaped switching piece 33 is formed on the outer surface of the upper peripheral wall end facing the opening 31, and a clearance groove 34 is provided at the base end of the peripheral wall 29 to avoid contact interference with the positive connection lead 6 </ b> A. Is formed. The stepped portion 32 receives the lower surface of the tip of the connection lead 6K on the negative electrode side and prevents the connection lead 6K from contacting the peripheral surface of the battery 2 on the lower side.

  When the switch piece 3 is switched from the OFF position (state shown in FIG. 1) to the ON position (state shown in FIG. 4), the contact state between the connection lead 6K on the negative electrode side and the peripheral surface of the battery case 2a is ensured. As shown in FIG. 5, the center position P2 of the battery 2 is eccentric from the rotation center position P1 of the switch piece 3 so that the LED 1 can be lit in a stable state at all times.

  Specifically, when the switch piece 3 is in the OFF position as shown in FIG. 5, the center position P2 of the space surrounded by the peripheral wall 29 and the bottom wall 28, that is, the center position P2 of the battery 2 is set to the circle center of the bottom wall 28. The position P1, that is, the rotation center position P1 of the switch piece 3, is decentered in the 8 o'clock direction of the timepiece dial.

  As described above, when the center position P2 of the battery 2 is eccentric with respect to the rotation center position P1 of the switch piece 3, when the switch piece 3 is rotated counterclockwise and turned on, it is indicated by an imaginary line. Thus, the battery 2 can be moved closer to the connection lead 6K and can be pressed against the connection lead 6K. Furthermore, when the wedge-shaped switching piece 33 is retracted from between the connection lead 6K and the battery case 2a, the connection lead 6K swings in a direction approaching the battery case 2a by its own elasticity.

  Therefore, in a state in which the switch piece 3 is displaced to the ON position, the connection lead 6K and the battery case 2a can be brought into electrical contact with certainty and the LED 1 can be turned on. Even when the luminaire is subjected to a drop impact, the connection lead 6K does not fall into contact failure, and a stable contact state can be obtained.

  In order to hold the switch piece 3 switched to the on position or the off position, a click mechanism is provided between the bottom wall of the battery tray 25 and the inner bottom wall of the rear case 4B facing the operation window 17. . In FIG. 4, the click mechanism includes a rib-shaped protrusion 35 formed on the inner bottom wall of the rear case 4 </ b> B and a pair of left and right engaging recesses 36 formed on the bottom wall of the battery tray 25. When this occurs, the rib 37 disposed adjacent to the left and right engaging recesses 36 rides over the projections 35 to cause a click feeling.

  The fixture 5 is integrally provided with a ring portion 38 having a round hook shape and a horizontal mounting ring 39 formed at the upper end of the ring portion 38, and the mounting ring 39 is externally connected to the connecting boss 11. It is integrated with the main body case 4. In FIG. 6, the mounting ring 39 is formed with a keyhole-shaped connecting hole 40, and the nodule protrusion 41 is formed in a continuous waveform only in the arc portion of the inner surface thereof. The joint protrusion 41 and the longitudinal ribs 13 provided on the front and rear peripheral surfaces of the connecting boss 11 constitute a joint structure for holding the main body case 4 at an arbitrary rotational position. More specifically, every time the user moves over the joint protrusion 41, the vertical rib 13 falls into the recess between the adjacent joint protrusions 41, thereby holding the main body case 4 in a non-movable position.

  The switch piece 3, the front case 4A, the rear case 4B, and the fixture 5 are all made of polymethylpentene resin (TPX resin = registered trademark), which has high heat resistance and chemical resistance and can be sterilized by autoclave. It is. For example, after the lighting device is used in dentistry, other patients are prevented from secondary infection by bacteria or viruses attached to the main body case 4 or the like.

  The lighting fixture having the above configuration is assembled by the following procedure. First, after the two batteries 2 are loaded on the battery tray 25, the switch piece 3 is inserted into the rear case 4 </ b> B, and the operation knob 26 is exposed from the operation window 17.

  Next, the positive connection lead 6A is inserted into the recess 30 provided in the bottom wall 28 of the battery tray 25 and brought into contact with the sealing plate 2b, so that the negative connection lead 6B faces the peripheral surface of the upper battery case 2a. . At this time, the end portion of the connection lead 6B is received by the step portion 32, and further, the temporarily assembled state can be held by the side wall of the rear case 4B. In this state, while fitting the light emitting bulb 1a of the LED 1 into the cylindrical wall 9, the fitting wall 10 of the front case 4A is fitted on the fitting wall 19 of the rear case 4B, and is provided on both fitting walls 10 and 19. The engagement protrusion 20 and the engagement hole 21 are engaged with each other.

  In the state where the front and rear cases 4A and 4B are fitted as described above, as shown in FIG. 4, the front and rear four positions on the periphery of the bottom wall 28 of the battery tray 25 are positioned and clamped by the positioning ribs 14 and the receiving surface 18. The entire switch piece 3 is supported so as to be reciprocally rotatable. Further, the flange wall 1b projecting from the base end of the light emitting bulb 1a is received by the end portion of the cylindrical wall 9, and the light emitting bulb 1a is positioned forward and backward.

  At this time, the connection lead 6K on the negative electrode side is in contact with the peripheral surface of the upper battery case 2a by its own elasticity. When the switch piece 3, the front case 4A, the rear case 4B, and the fixture 5 are sterilized by heating, the LEDs 1 and the battery 2 can be detached by disassembling each member in the reverse procedure described above.

  When using the luminaire, with the operation knob 26 displaced from the off position to the on position and turning on the LED 1, for example, as shown in FIG. 7, the ring portion 38 of the fixture 5 is attached to the fingertip, The ring portion 38 is moved around the finger, or the body case 4 is rotated with respect to the fixture 5 to adjust the irradiation direction of the LED 1 to a desired position and direction, and highly directional illumination light is locally applied. To focus on. After use, the operation knob 26 may be displaced to the off position shown in the figure to turn off the LED 1.

  When the operation knob 26 of the switch piece 3 is displaced from the on position to the off position, the switching piece 33 rotates in the clockwise direction in FIG. 4 and is retracted between the connection lead 6K and the battery case 2a, and the connection lead 6K. Is separated from the battery case 2a and kept in a non-conductive state as shown in FIG. At this time, the connection lead 6K is elastically deformed. Therefore, when the switch piece 3 is operated to the ON position again as described above, the connection lead 6K can approach the battery 2 by the amount of elastic deformation.

  FIG. 8 shows another embodiment of the present invention in which the switch structure is changed. The battery 2 is loaded in the battery tray 25 in the posture opposite to that of the previous embodiment, and the connection lead on the positive electrode side that contacts the sealing plate 2b. 6A can be turned off by a switch piece 3 that slides back and forth back and forth.

  The tip of the connecting lead 6A is bent in a reverse hemispherical shape, and this bent portion is in elastic contact with the sealing plate 2b. When the switch piece 3 is slid from the position shown in FIG. 7 to the front of the case, the switching piece 33 slips between the connection lead 6A and the sealing plate 2b to hold the connection lead 6A in a non-conductive state. When the switch piece 3 is slid in the opposite direction, the connection lead 6A is returned and displaced by its own elasticity and is pressed against the sealing plate 2b. Since the others are substantially the same as the previous embodiment, the same reference numerals are assigned to the same members and the description thereof is omitted.

  As can be understood from the above embodiment, the object to be operated by the switching piece 33 may be any of the connection leads 6A and 6K of the positive electrode and the negative electrode. Further, the switch piece 3 may be configured to reciprocate between an on position and an off position.

  The attachment 5 can be formed in a clip shape, and in that case, a lighting device can be attached to a shirt pocket, a hat collar, or the like. If necessary, the fixture 5 may be configured so that a lighting fixture can be attached to the temple portion of the glasses. The fixture 5 can be composed of a pair of male and female hook-and-loop fasteners.

  In addition to the above embodiment, when the connection lead 6K (or 6A) is pressed against the battery 2 by a spring, the center position P2 of the battery 2 and the rotation center position P1 of the switch piece 3 are set to the same position. Can be provided. The battery tray 25 can be omitted. The LED 1 does not need to be a bullet-type LED. For example, the LED 1 includes a reflection mirror inside the LED body, and can exhibit a luminous efficiency more than twice that of the bullet-type LED (for example, DR of OMRON ELECTRONICS CO., LTD. -LED) can be applied. The number of batteries 2 used need not be two, but may be one or three or more. Further, the structure may be a battery structure other than the button type.
