Description

Lighting Lamp Technical Field

The present invention relates to an illumination lamp which is provided with a plurality of light sources so as to be switchable, and which can be suitably used for illumination when climbing or working in a dark place. Background art

Illumination lamps mainly used for the above-mentioned applications include Japanese Patent Publication No. Hei 210-210, Japanese Patent Publication Hei 9-224304, and Japanese Patent Laid-open No. Hei 7-785. The disclosures of each of the 01 publications are known. The lamp device described in Japanese Patent Publication No. 2-105210 (hereinafter referred to as the first prior art) is a tubular body having a reflector inside, and its opening is made of a transparent plate. Rotating the covered ring-shaped member to move the reflector therein, and selectively displacing the relative position of the reflector with respect to the single bulb to the first and second positions; When the reflector is displaced to the first position, the luminous flux of the bulb is diffused the most, and when the reflector is displaced to the second position, the luminous flux of the bulb is switched so as to converge most, and the light is emitted It has become.

Further, the headlamp described in Japanese Patent Application Laid-Open No. Hei 9-222430 (hereinafter referred to as a second prior art) switches the brightness of a single light bulb in two stages by rotating a switching knob. By changing the brightness of the bulb according to the surrounding brightness, it is possible to suppress unnecessary consumption of the battery. Further, the electric lighting lamp (hereinafter referred to as a third conventional technique) described in Japanese Patent Application Laid-Open No. 7-78051 has two light sources arranged side by side and individually corresponds to each of these light sources. And two switches of an electric circuit for controlling the turning on and off of the two light sources. However, the lighting lamps of the above-mentioned prior arts are mainly intended to be used as head lamps mounted on the head, and are free to use both hands when climbing a mountain, exploring a cave, or in a dark place. It can be suitably used when working with If the illumination lamp used for such an application is provided with two light sources as in the third related art, when one of the light sources is cut off, it can be switched to the other light source immediately and used. This is advantageous because light sources having different illuminances, luminescent colors or lifespans can be mounted and used by appropriately switching according to the situation. However, in the first and second prior arts described above, the brightness of the light bulb and the like can be switched in two stages, but since only a single light bulb is provided as a light source, the practical The objective effect cannot be obtained.

On the other hand, the electric lighting lamp of the third prior art described above has two light sources, but has two reflectors corresponding to these light sources, respectively. In addition, the shape of each reflector becomes small, and the light of each light source cannot be sufficiently diffused or converged, and illumination light of sufficient brightness cannot be obtained. Conversely, if each reflector has the required size, the shape of the entire device becomes large, which is difficult to use as a headlamp. In addition, since this electric lighting lamp has two reflectors and two switches, the number of parts is increased, which complicates the configuration and increases the size. become.

In view of the above, the present invention has been made in view of the above-mentioned conventional problems, and it is possible to selectively select a plurality of light sources in a simplified and miniaturized configuration to emit light. The objective is to provide an illumination lamp that can obtain the required illuminance for the light source. Disclosure of the invention

In these figures, the lamp body 1 is fixedly mounted on a base unit casing 7 and a reflector 8 fixed to the base case 7, and is rotatably fitted to and supported by the reflector 8. A movable unit composed of a light source moving member 9 and a rotating operation ring body 10 fixedly connected to the light source moving member 9, and first and second light sources 11 and 12 made of electric balls are juxtaposed. The light source holder 13 held in the state is configured as a main component. In the base casing 7, a mounting plate 14 (FIG. 4) to which the belt holder 2 is fitted from above and fixed by screws (not shown) is mounted on the outer side of the dish-shaped bottom by a support shaft (not shown). It is provided rotatably. As shown in FIG. 6C, which is a front view of the base casing 7, a non-circular mounting recess 18 is provided in a recess 17 at the center of the inner surface. A mounting hole 19 is formed in the portion, and a guide bin 20 is provided in the lower portion of the inner surface. Further, on the inner surface of the base casing 7, a pair of arc-shaped connecting thin pieces 21 and 21 are adhered in an arrangement following a semicircular arc, and the connecting thin pieces 21 and 21 are connected. Connection terminals 22 are provided at respective ends adjacent to each other with a slight space therebetween. The connection cord 4 extending to the above-mentioned battery case 3 is electrically connected to the connection terminal 22.

The reflector 8 has a conical outer shape, the inner surface of which is a parabolic reflecting mirror surface 8a, and a rectangular parallelepiped holding portion 23 (FIG. 4) extends rearward from the center of the bottom. It is projected. The light source holder 13 is slidably fitted into the center of the holder 23, as shown in FIG. 5, which is a rear view of the reflector 8 and the light source holder 13 in a disassembled state. A slide groove 24 is formed so as to extend in the horizontal direction perpendicular to the axis of the reflector 8 and a pair of light sources 11 and 1 are formed at the center of the bottom of the slide groove 24. A light source insertion hole 27 is formed to movably insert the light source 2 in a predetermined range in the horizontal direction.

The light source holder 13 has an elongated block-like overall shape, and a pair of light sources 11 and 12 each having a base (not shown) screwed into and attached to the front side thereof. It has a socket (not shown). Also, as shown in FIG. 5, the light source holder 13 has a positive contact 28 electrically connected to one positive electrode of each of the sockets along the side surface. And a pair of negative contact portions 29, 30 electrically connected individually to the negative electrode portions of both socket portions are provided along the other side surface at predetermined intervals. I have.

The light source holder 13 is slidably held in the slide groove 24 of the holding portion 23 of the reflector 8 as described above. That is, as shown in FIG. The contact pieces 31a and 32a of the connection terminal plates 31 and 32 on both the positive and negative sides are inserted into the slide grooves 24 of At the same time, the light source holder 13 is inserted, and a non-circular mounting plate 33 that can be fitted into the mounting recess 18 of the base casing 7 is formed by the light source holder 13 and both connection terminal plates. 3 1 and 3 2 are covered. As shown in FIG. 6A, two small screws 34 are attached to each of the through holes (shown in FIG. 5) 33 a of the mounting plate 33 and the connection terminal plate 3 on both sides. 1 and 3 2 insertion holes (shown in Fig. 5)

It is fixed to the holding portion 23 by being screwed into 23 a.

Therefore, as shown in FIGS. 4 and 6A, the positive and negative connection terminal plates 31 and 32 are arranged so as to protrude both up and down with respect to the mounting plate 33 and the end face of the holding portion 23 and the mounting plate 3. The light source holder 13 is slidably held in the slide groove 24 in a state where the light source holder 13 is prevented from falling off by the mounting plate 33. The light source holder 13 moves left and right within the slide groove 24 within a range in which one of the light sources 11 and 12 comes into contact with the edge of the elongated light source insertion hole 27 facing in the longitudinal direction. Can be moved.

The reflector 8 to which the light source holder 13 is slidably mounted as described above is rotated by fitting the mounting plate 33 into the mounting recess 18 of the base casing 7 as shown in FIGS. In the stopped state, as shown in FIG. 3, the fixing screw 37 is attached to the mounting hole of the base casing 7 (shown in FIG. 6C) 19 through the screw hole of the mounting plate 33 (shown in FIG. 5). By being screwed into 3 c, it is integrally fixed to the base casing 7.

When the reflector 8 and the base casing 7 are integrally fixed in the above-described relative positional relationship, as is clear from the comparison between FIGS. 6A and 6C, the positive and negative connection terminal plates 31 of the reflector 8 , 32 respectively come into contact with the pair of connecting flakes 21, 21 of the base casing 7 while being electrically connected. Therefore, the connection terminal plates 3 1 on both the positive and negative sides of the reflector 8

3 2 is always connected to the battery in the battery case 3 through the connecting thin piece 21 and the connecting terminal 22 and the connecting cord 4 of the base casing 7 irrespective of the rotational position of the light source moving member 9 described later. It is in an electrically connected state. In addition, the positive contact portion 28 having substantially the same length as the length direction of the light source holder 13 shown in FIG. Irrespective of the contact point, the contact piece 3 1a of the positive connection terminal plate 31 is always electrically connected to the contact piece 31a, but the pair of negative contact sections 29, 30 are connected to the light source holder 13 Only when it is located at the center with the movement of, it contacts with the contact piece 32a of the negative connection terminal plate 32 while being electrically connected. Details of this will be described later.

As shown in FIGS. 3 and 4, the light source moving member 9 is rotatably fitted to a cylindrical support tube portion 8b integrally formed outside the reflecting mirror surface 8a of the reflector 8. As shown in FIG. 6B, a circular operating hole 39 having a diameter larger than the length of the light source holder 13 is provided in the center of the bottom of the light source moving member 9 as a whole in a circular container shape. It is formed so as to be eccentric to one side with respect to the center of the light source moving member 9. A semicircular guide groove 40 is formed on the inner surface of the container of the light source moving member 9 in a concentric arrangement along the outer peripheral edge. In addition, a positioning outer flange 44 protrudes from the body at a suitable position on the outer peripheral surface of the light source moving member 9.

The light source moving member 9 is assembled in the following procedure when assembling the lamp body 1. First, prior to the integration of the reflector 8 and the base casing 7 described above, the holder 23 with the light source holder 13 fitted in the slide groove 24 is inserted through the operation hole 39. After that, the light source moving member 9 is put on the outer peripheral surface of the support cylindrical portion 8b of the reflector 8. While maintaining this state, as shown in FIG. 4, the guide bin 20 of the base casing 7 is inserted into the guide groove 40 of the light source moving member 9 itself, and the mounting is fixed to the holding portion 23. The plate 33 is fitted into the mounting recess 18 of the base casing 7, and the reflector 8 and the base casing 7 are fixed with the fixing screws 37.

As described above, the light source moving member 9 is rotatably supported while the main body portion slides on the outer peripheral surface of the support cylindrical portion 8 b of the reflector 8, and the positioning outer flange portion 44 is formed of a base. It is incorporated in a state in which it is slidably abutted on the outer peripheral end surface of the casing 7. The rotation range of the light source moving member 9 is restricted to a rotation angle of about 90 degrees at which the guide bin 20 contacts both ends of the guide groove 40. When the light source moving member 9 rotates, the operating hole 39 arranged eccentrically from the center of the light source moving member 9 moves the light source holder 13 right and left along the slide groove 24. Details of this will be described later. The front opening of the rotary operation ring body 10 is covered with a transparent plate 41 for protecting the reflecting mirror surface 8a of the reflector 8 and the pair of light sources 11 and 12. The rotating operation ring body 10 is configured such that a female screw part 42 provided on the inner peripheral surface of the rotating operation body 10 is screwed into a male screw part 43 formed on the outer peripheral surface of the light source moving member 9, and the distal end surface in the screwing direction is a light source. The moving member 9 is integrated with the light source moving member 9 by being fastened to a state in which the member is pressed against the positioning outer flange portion 44. Therefore, when the rotation operation ring body 10 is rotated while grasping the outer peripheral surface thereof, the light source moving member 9 is rotated integrally with the rotation operation ring body 10. When replacing one of the light sources 11 and 12 with a broken ball, replace the light source 11 or 12 with a new one by loosening the rotating ring 10 and removing it from the light source moving member 9. The light sources 11 and 12 can be easily attached to and detached from the socket of the light source holder 13 by inserting a finger into the reflecting mirror surface 8a of the reflector 8 from above.

In particular, in FIG. 3 and FIG. 4, even members for waterproofing such as rubber rings, o-rings or packing, and members necessary and inevitably attached to the lighting lamp are not relevant to the gist of the present invention. Illustration of members and the like is omitted for the sake of convenience in order to simplify the drawing and facilitate understanding of the contents. However, it goes without saying that this kind of member is appropriately provided for practical use.

Next, an operation of selectively turning on the pair of light sources 11 and 12 in the illumination lamp by rotating the rotating operation ring body 10 will be described with reference to FIGS. 7A to 7E. I do. FIG. 7A shows a state in which the guide pin 20 of the base casing 7 is located at the center of the guide groove 40 of the light source moving member 9. At this time, the pair of light sources 1 1 and 1 2 are located on both sides of the center S of the illumination lamp itself, that is, the center S of the parabolic reflecting mirror surface 8 a of the reflector 8. The pair of negative contact portions 29, 30 of the holder 13 are located on both sides of the contact piece 32a of the negative connection terminal plate 32, and both contact the contact piece 32a. Absent. Therefore, the light sources 11 and 12 are in the light-off state because only the positive terminal of the socket is connected to the battery case 3 and the negative terminal is not connected.

Next, when the rotating operation ring body 10 is rotated leftward L from the state of FIG. 7A, As shown in FIG. 7B, the light source holder 13 is provided with a hole edge surface of an operation hole 39 eccentric to one side with respect to the center S of the light source moving member 9 which is integrally rotated with the rotary operation ring body 10. , And moves leftward along the slide groove 24. When the light source moving member 9 is rotated by an angle of 90 ° from the state shown in FIG. 7A, the guide bin 20 comes into contact with the left end of the guide groove 40 to prevent the rotation. At this time, the light source holder 13 is in a state in which the right light source 12 is positioned at the center S as shown in FIG. 7C, and the right negative contact portion 29 on the right side is the negative side of the holding portion 23. The contact pieces 32 a of the connection terminal plate 32 are superposed and electrically connected.

As a result, the light source 12 positioned at the center S is connected to the battery in the battery case 3 through the negative connection terminal board 3 2 because the negative contact portion 29 is connected to the battery in the battery case 3, and the drive power is supplied from the battery to light up. I do. At this time, the light source 1 and 2 are turned on in a state where the light source is positioned at the center, which is the focal position of the reflecting mirror surface 8a of the reflector 8, so that the light flux is efficiently reflected after the light is reflected by the reflecting mirror surface 8a. The light is converged or diffused and radiated forward through the transparent plate 41. In order to turn off the light source 12, it is only necessary to rotate the rotating operation ring body 90 90 degrees clockwise R to the state shown in FIG. 7A.

On the other hand, when the rotating operation ring body 10 is rotated rightward R from the state shown in FIG. 7A, as shown in FIG. 7D, the light source holder 13 is rotated integrally with the rotating operation ring body 10. Since it is pressed by the hole edge surface of the operation hole 39 of the moving member 9, it moves rightward along the slide groove 24. When the light source moving member 9 is rotated by an angle of 90 ° from the state shown in FIG. 7A, the guide pin 20 comes into contact with the right end of the guide groove 40 to prevent the rotation. At this time, the light source holder 13 is in a state where the left light source 11 is positioned at the center S as shown in FIG. 7E, and the left negative contact portion 30 is connected to the negative side of the holding portion 23. The contact pieces 32 a of the connection terminal board 32 are superposed and electrically connected.

Therefore, the light source 11 positioned at the center S is connected to the battery in the battery case 3 through the negative connection terminal plate 3 2 because the negative contact 30 is connected to the battery in the battery case 3. I do. At this time, since the light source 11 is turned on in a state where it is positioned at the central portion which is the focal position of the reflecting mirror 8a of the reflector 8, its light emission is performed by the reflecting mirror 8a. After being reflected, the light flux is efficiently converged or diffused, and is irradiated forward through the transparent plate 41.

The holder holding plate 84 passes through the two light sources 72 and 73 mounted on the light source holder 74 so that the length of the light source holder 74 does not hinder the movement in the left and right direction. The light source passage hole 84b having a horizontally long shape is formed.

By rotating the switch lever 62, the light source holder 74 rotates the engagement piece 74d by the operation bin 79b of the switch cam 79 which is rotated integrally with the switch lever 62. By being pressed in the moving direction, the guide ribs 54 are moved in the left-right direction while sliding on each guide rib 54d. At this time, as with the first embodiment, only one of the light sources positioned at the center of the reflector 60 is connected to the batteries of the battery case 57, as in the first embodiment. Lights automatically when connected.

Next, a configuration for selectively connecting the two light sources 72 and 73 to a battery will be described. As shown in Fig. 16, inside the battery case 57, the battery case 57 A positive-side battery lead 87, which has a positive-side contact portion 87a at one end connected to the positive side of a plurality of batteries that are housed and connected in series or in parallel with each other, and a negative electrode, connected to the negative side of the battery A negative electrode battery lead 88 having a side contact portion 88a at one end is disposed and housed at predetermined upper and lower positions as shown in FIG. One end of the positive switch lead 89 is electrically connected to the other end of the positive battery lead 87. One end of a negative switch lead 90 is electrically connected to the other end of the negative battery lead 88, and the other end of the negative switch lead 90 is connected to the other end of the negative switch lead 90. One end of the switch spring 91 is electrically connected to one end of the switch spring 91 by a screw 92. In this illumination lamp, when the switch lever 62 is turned to the left or right, the light source holder is As the light source holder 74 moves in the left or right direction, the insulating block 81 moves together with the light source holder 74. At this time, as shown in FIG. 15, the positive contact 809 a protruding from the other end of the positive switch lead 89, regardless of the position of the light source holder 74 that moves in the left-right direction, It is always in sliding contact with a contact portion 8 2 b serving as a common contact for the terminal portion 82, and is always electrically connected to the positive electrode side of each battery via a positive electrode battery lead 87. On the other hand, the negative contact 91 a protruding from the other end of the switch spring 91 is connected to one of the negative sides positioned at the center of the reflector 60 as the light source holder 74 moves left and right. The contact portion 83 b of the contact terminal portion 83 is selectively contacted, and is electrically connected to the negative electrode side of each battery. In other words, one of the two light sources 72, 73 is selected by turning the switch lever 62, and the switch is turned on when energized.

The switch lever 62 is in a switch-off state at the center as shown on the operation seal 93 in FIG. One of the light sources 72 and 73 is positioned at the center of the reflector 60, and is electrically selected and energized to light. For this purpose, the two negative contact terminal portions 8 3 are arranged side by side with an interval for switch-off, and the contact portion 8 2 b which is the upper surface of the positive contact terminal portion 8 2 is switched on. , Switch-off and switch-on. Note that this embodiment In this example, as described on the operation sticker 93, a case where a high-luminance light source 73 is arranged on the right side and a low-luminance light source 72 is arranged on the left side is illustrated.

This illumination lamp is different from that of the first embodiment only by rotating the switch lever 62 to selectively position the two light sources 72, 73 at the center of the reflector 60. Similarly, the selected light source 72 or 73 is automatically connected to the battery. At the same time, since the selected light source is emitted at the focal position of the reflecting mirror 60a of the single reflector 60, the luminous flux is efficiently reflected after the light is reflected by the reflecting mirror 60a. It is converged or diffused and illuminated forward through lens 59.

Further, this illumination lamp has an advantage that the size of the spot can be changed depending on the size of the object to be illuminated. That is, by gripping and rotating the outer peripheral surface of the rotating operation ring body 61, the lens 59 and the reflector 60 move in the front-rear direction while maintaining the relative positional relationship of the three members together with the rotating operation ring body 61. The focal position is adjusted by changing the relative position of the lens 59 and the reflecting mirror surface 60a with the selected light source 72 or 73 in the front-rear direction, and the spot size is adjusted. Can be changed.

In this illumination lamp, the switch lever 62 can be locked by the lock button 63 when not in use. FIG. 17A to FIG. 17C are diagrams for explaining the operation of the lock button 63, FIG. 17A is an enlarged rear view partially cut away, and FIG. 17B is a switch lever. Fig. 17C is a cut-away right side view showing an enlarged view of a part of a state where 62 is locked by a lock button 63, and Fig. 17C is an enlarged view of a part of the unlocked state of a switch lever 62. It is.

In the switch lever 62, a lock button 63 is fitted into a mounting recess 62c at the center of the upper operation unit. When the switch lever 62 is located at the center as shown in FIG. 17A, the operation of the switch is off as described above, and when the lighting lamp is carried in this state, the switch lever is turned off. It is desirable to lock one 62 in the off state. Therefore, in such a case, the operation is performed such that the operation surface 63 a formed on the upper and lower surfaces of the lock button 63 is pressed in the direction of the arrow in FIG. 17B. As a result, the lock button 63 is attached to the switch lever 6 in the locking recess 63c at the tip of the engaging piece 63b. When the locking projections 6 2 d are fitted, they are held at the hooking position pushed forward, and the stopper piece 6 3 d below the hooking button 63 is attached to the base casing. Corresponding part of 54 Engage with the locking walls 54 f formed on the left and right sides. Therefore, even if the switch lever 62 is rotated in the above state, the stopper piece 6 3 d of the lock button 63 that rotates integrally with the switch lever 62 changes the position of the left or right locking wall 54 f. The abutment with the crab prevents accidental rotation.

To release the lock of the switch lever 62, as shown in Fig. 17C, press the operation surface 63a of the lock button 63 in the direction of the arrow to move the lock button 63 outwardly. The engagement of the stopper piece 63d of the lip button 63 with the corresponding wall surface 54f of the base casing 54 may be released.

Further, in this illumination lamp, means for preventing the opening / closing lid 67 of the battery case 57 from falling off is provided. That is, as shown in FIG. 10 and FIG. 11, the battery case 57 and the opening / closing lid 67 are provided with locking pieces 57 a and 67 a at the lower portions thereof, respectively. Both hanging pieces 57 a and 67 a are connected to each other by a thin connecting cord 94. In addition, instead of the retaining piece 57 a of the battery case 57, a locking slit was formed in the belt holder 68, and a knot was provided at the leading end of the connecting cord 94 in the locking slit. A portion near the end may be fitted and connected.

Further, as a more preferable means for preventing the opening / closing lid 67 from falling off, a configuration as shown in FIG. 18 which is an exploded perspective view showing the battery case 57 in an enlarged manner can be employed. In other words, a hook-shaped hook portion 57b is formed at one end of an opening end serving as a battery loading port of the battery case 57, and a pair of ridges 57c is formed at the other end. On the other hand, the opening / closing lid 67 has a hook hook 67b at one end for inserting and hooking the hook portion 57b, and two engaging members for fitting a pair of ridges 57c. An L-shaped engaging piece 67d having a mating groove 67c is formed at the other end. In this drop-out prevention means, when the battery is replaced, when the opening / closing lid 67 is opened to the battery case 57, the engagement between the hook hook 67b and the hook part 57b causes the opening / closing lid 67b to engage. The battery can be smoothly replaced even when the device is used in darkness such as night fishing without falling off the battery case 57. In addition, At the open end of the pond case 57, an O-ring 97 made of an elastic body that seals a gap between the open / close lid 67 and the water tightly is attached.

Since the lighting lamp of the present invention needs to have a watertight waterproof structure in view of its use, the 0 ring 97 is disposed between the battery case 57 and the opening / closing lid 67 as described above. In addition to the above, as shown in Fig. 16, a waterproof 0 ring 77 is attached to the front end face of the support shaft 62 a of the switch lever 62, and further, the base casing 5 4 The O-ring 98 shown in FIG. 15 is mounted between the outer peripheral surface of the lens and the inner peripheral surface of the lens 59. As a result, this lamp has a waterproof structure that can withstand use in rainy weather, near the coast, or near rivers. As the battery to be loaded in the battery case 57, any of a dry battery and a secondary battery can be used, but a lithium secondary battery is preferably used. Industrial applicability
