  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present embodiment shows an example in which the configuration of the present invention is applied to a metal light which is an example of a portable lighting device.

In FIG. 1, a metal light (portable lighting device) 1 according to an embodiment includes a LED board 5 sandwiched between an LED socket A3 and an LED socket B4 attached to a case 2 and switches a switch board 6 (described later). Is attached to the bean ball base 26 via one end portion configured to light the LED 7 and the middle base 10 in which the switch holder A8 and the switch holder B9 holding the switch board 6 are incorporated (bean Sphere) To connect the bean sphere lead A13 and the bean sphere lead B14 sandwiched between the socket A11 and the (bean sphere) socket B12, and to turn on the miniature sphere (bean sphere) 15 by switching the switch board 6 (described later). The one end part (on the opposite side of LED7) configured with a single portable illuminator, the irradiation range, brightness and battery life that match the usage location and usage conditions And it is configured so as to be selectively used.

  On the LED substrate 5 side of the case 2, an aspherical lens 19 is held on the optical axis L of the light emitted from the LED 7 by being sandwiched by the lens cover 18 via the LED base 16 and the O-ring 17. The LED base 16 is rotated and linearly moved in the front-rear direction by a screw feed structure to change the separation distance of the aspherical lens 19 with respect to the LED 7 on the optical axis L, thereby adjusting the irradiation range. Has been.

  An LED base 16 for focus adjustment having an illumination port 120 formed in the center is rotatably mounted on the LED 7 side of the case 2, and the diameter of light emitted from the illumination port 120 is adjusted by rotating the LED base 16. can do. Further, the middle base 10 is disposed on the miniature ball (bean ball) 15 side, and by rotating it, the battery can be taken in and out by removing it from the case 2 with a screw feed structure.

  Further, the middle base 10 is provided with a switch rubber 21 configured as a push button and a switch pin 22 and a switch guide 23 for moving the switch pin 22 up and down in the vertical direction. When the push switch 24 is pressed, the LED 7 can be controlled to be turned on, the miniature sphere (bean sphere) 15 is turned on, and the light is completely turned off.

The middle base 10 is rotatably mounted with a focus adjustment bean ball base 26 having an illumination port 225 formed at the center thereof, and the diameter of light emitted from the illumination port 225 is adjusted by rotating the same. be able to.
On the side of the miniature sphere (bean sphere) 15 of the case 2, a middle base 10 in which a bean sphere socket A 11 and a bean sphere socket B 12 are attached is provided. A bean ball base 26, a reflecting mirror 27 that reflects light, an O-ring and a lens 29 that hold the bean ball base 26, and a lens 29 are disposed on the optical axis L of the light emitted from the light. By doing so, the illumination range can be adjusted by linearly moving in the front-rear direction by the screw feed structure to change the separation distance on the optical axis L with respect to the miniature sphere (bean sphere) 15 of the reflecting mirror 27.

  The LED 7 emits light when a forward current in which two batteries 30 are connected in series flows as shown in FIG. 3, and light having a directional center on the optical axis L by a lens formed on the surface of the LED 7. Is emitted. The LED 7 boosts the voltage applied by the two batteries 30 in the LED substrate 5 so that it can emit light with a constant brightness even in the range of 3V to (1.7V), and at the same time, the LED 7 The current is limited by the current limiting resistor in the LED substrate 5 so that the current flows.

  The light emitted from the LED 7 is irradiated from the illumination port 120 as parallel light substantially parallel to the optical axis L due to the aspherical design of the aspherical lens 19. The separation distance from the LED 7 of the aspherical lens 19 that can collect the light emitted from the LED 7 into parallel light is one point, and the separation distance before and after that is the condensing direction or the diffusion direction. Accordingly, by rotating the LED base 16 and changing the position of the aspheric lens 19 on the optical axis L, the illumination range at the irradiation position can be changed. At this time, since the illumination range is illuminated by the light condensed as parallel light by the aspheric lens 19, the illumination range is illuminated to a substantially average brightness.

  The LED substrate 5 is supplied with voltage from two batteries 30 as a power source, whereas the positive electrode side is electrically connected to the LED substrate 5 from the positive electrode side of the two batteries 30 through the plus lead 31, while the negative electrode Normally, the side is electrically connected to the LED substrate 5 through the case 2, but the product of the present invention is configured as a positive side for lighting the miniature ball (bean ball) 15, so that the negative electrode passing through the inside of the case 2 is separately provided. A side conduction circuit is newly provided to constitute a circuit that can be lit. As a content, a battery case (insulation guide) 32 designed so that the maximum battery can be placed inside the case 2 is disposed, and the LED board is disposed (arranged) at a position not contacting the case 2 and the two batteries 30. A negative lead 33 that is soldered and a contact plate 34 that can be connected to the lead by soldering are disposed in a battery case (insulation guide) 32 so that power on the negative electrode side can be supplied.

  Further, on the negative electrode side, a circuit for lighting the LED 7 by the push switch 24 and a circuit for lighting the miniature ball (bean ball) 15 are provided. As a circuit for lighting the LED 7, a switch lead A 36 that passes through a battery spring 35 that is in contact with the negative electrode side of the two batteries and can be conducted by soldering to the switch board 6 that is in contact with the battery is disposed. I try to conduct. When the LED 7 is turned on, the push switch 24 conducts by contacting the switch terminal 139 when the contact 38 is rotated at a certain angle by the rotating shaft 37 inside, and the switch lead B 40 and the switch lead B 40 are connected via the switch substrate 6. By making contact with the cathode plate 41 and the cathode spring 42, the power supply on the negative electrode side can be supplied.

  Here, in order to insert the two batteries 30 serving as power sources into the case 2, the middle base 10, which also serves as a battery lid, is detachable by screwing the case 2. The cathode spring 42 for making contact with the contact plate 34 is configured to be detachable by being arranged on the middle base 10 side. However, when the middle base 10 is attached to the case 2, it is sufficient to take advantage of the spring characteristics. Contact pressure is also secured. Further, the push switch 24 contacts the switch terminal 243 at an angle of 180 ° with respect to the switch terminal 139 using the contactor 38 for lighting the LED 7 by the rotating shaft 37 inside when the bean ball is turned on. The power is supplied to the miniature sphere (bean sphere) 15 through the switch board 6 and the switch lead C44 and the bean sphere terminal A45, and the positive side of the miniature sphere (bean sphere) 15 contacts the bean sphere terminal B46. The middle base is conducting. Also here, the middle base 10 is detachable in order to insert two batteries 30, and the case 2 made of aluminum material and the middle base 10 are electrically connected when they are attached by screw rotation. It has become.

  The aspherical lens 15 applied to the metal light 1 is manufactured by forming a transparent resin using a mold having a predetermined aspherical shape, so that it can be configured relatively inexpensively. The lens can solve the problem that the illumination range cannot be illuminated to an average brightness.

  Since the present metal light 1 is a portable lighting device that is used as illumination mainly when sufficient brightness is required in the dark, it is preferable that the brightness can be adjusted according to the place of use and the state of use. For example, when illuminating a foot while walking, safety can be improved if the light is diffused and light is scattered, and strong illumination is not necessary because hand illumination such as viewing a map is a close distance. A single portable illuminator can be used for the irradiation range, brightness, and battery life that match the location and conditions of use.

Since the present metal light 1 is also used as a night illumination tool in the outdoors, it is exposed to severe temperature environments such as a low temperature environment such as winter mountains and a hot summer sun. It is not uncommon to use it during snowfall or in the rain. Therefore, it is necessary to take measures to prevent a failure or change in characteristics due to a temperature change, and it is necessary to provide an enemy defense structure that prevents the occurrence of a failure due to water intrusion. An anti-fouling structure is configured by providing an O-ring at each fitting location where there is a risk of water intrusion.

  Further, the present metal light 1 is also robust due to the use of an aluminum material that can conduct to the exterior parts. However, as long as it is possible to examine measures against continuity, it is possible to make a configuration similar to the present metal light using resin for the exterior. In this embodiment, the push switch 24 is used. However, if a slide switch is used, there is an advantage that it can be determined which of the light A and the light B is lit.

  The present invention is mainly used for a portable lighting device used at night.
