  In the invention according to claim 1, the relative position between the light transmissive connection case and the main body case or the relative position between the light transmissive connection case and the front case is slid in a direction in which the entire apparatus extends to be separated from each other. Since the rear end opening of the light transmissive connecting case is spaced forward from the light source, most of the light emitted from the light source is connected to the side light transmissive link by the outer reflecting surface of the reflecting mirror. Since it is reflected toward the case, passes through the light transmission part and is emitted to the side periphery, if the main body case is gripped in this state, it can be suitably used as a signal lamp. On the other hand, if the relative position between the light transmissive connection case and the main body case or the relative position between the light transmissive connection case and the front case is set to an arrangement close to each other by sliding in the direction of shortening the entire apparatus, Since the light source is located in the rear end opening of the transmissive connecting case, most of the light emitted from the light source is reflected toward the front side by the inner reflection surface of the reflector, and forward from the front opening of the front case. Therefore, it can be used preferably by changing from a signal lamp to a headlamp if necessary.

Therefore, an unnecessary light ring-shaped illumination area is not formed around the illumination area corresponding to the light emitting portion irradiated and imaged forward by the condenser lens, and the illumination is easy to see.

  In the invention according to claim 7, when the operation is performed so that the entire apparatus is shortened so as to change from the signal lamp to the headlamp as necessary, the light source is automatically switched so as to be continuously lit. Etc. becomes unnecessary and becomes easy to use.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. 1 and 2 are longitudinal sectional views showing a portable LED lighting device according to an embodiment of the present invention.

Is contained. A plurality (four in this embodiment) of batteries 9 are detachably inserted into the battery storage portion 7 from one end opening in a state of being stored in the battery case 10 in an arrangement connected in series with each other. It is to be accommodated. On the outer peripheral surface in the vicinity of the front end of the battery housing portion 7, a locking projection piece 7a is projected outward.

  In this embodiment, only a single high-intensity white LED 11 is provided as the light source, but a high-intensity white LED 11 having a rated current of 350 mA and a maximum current value of 500 mA is used. That is, this illuminating lamp device can secure a desired luminance by a single high-intensity white LED 11. However, since the high-intensity white LED 11 has a large amount of heat generated because a large current flows, the first circuit board 13 on which the high-intensity white LED 11 is mounted uses a metal material having a high heat transfer coefficient. A wiring pattern is formed. The high-intensity white LED 11 is mounted on the first circuit board 13 in such a manner that the optical axis faces the front (upward in the figure) on the center line of the outer body of the device configured in a cylindrical shape. Yes.

  The battery lid case 4 is formed in a bottomed cylindrical shape and is detachably attached to the main body case 1 by screw connection. A support plate 17 is fixed in a fitted state near the opening end of the battery lid case 4, and a second circuit board 20 on which a control unit 19 having a power switch 18 is mounted is attached to the support plate 17. It is fixed by a screw 22 with a member 21 interposed. The power switch 18 controls the supply of driving power from the battery 9 to the high brightness white LED 11 by pressing.

  The second circuit board 20 is connected to a power supply terminal (not shown) of the battery case 10 via a connector 23 and is connected to the first circuit board 13 via a connection cord 24. Thereby, each battery 9 in the power supply case 10 supplies power to the high-intensity white LED 11 through the second circuit board 20, the connection cord 24 and the second circuit board 20 to emit light. The control unit 19 performs energization control to the high-intensity white LED 11 in response to the pressing operation of the power switch 18. The connection cord 24 has a length that allows the battery case 10 and the battery lid case 4 to be pulled out of the main body case 1, and the connection cord 24 is pulled when the battery case 10 and the battery lid case 4 are attached. In the main body case 1.

  In the front case 2, a reflecting mirror 27 that has a bowl-like appearance and is open at both ends, and a condensing lens 28 that is a convex lens having an aspherical shape, is a front end opening of the reflecting mirror 27. Are fixed to each other through a fixing member 29 in a coupled state in which the condenser lens 28 is fitted. The reflecting mirror 27 and the condensing lens 28 are fixed to the front case 2 in such an arrangement that their central axes coincide with the optical axis of the high-intensity white LED 11. The fixing member 29 is provided with a locking projection 29a projecting outward at the rear end.

  The inner reflection surface 27a of the reflecting mirror 27 having a bowl shape emits from the high-intensity white LED 11 when the high-intensity white LED 11 is disposed on the central axis in the rear opening as shown in FIG. It is formed on a curved surface that reflects the reflected light toward the front condenser lens 28. The condensing lens 28 is formed of transparent resin or transparent glass, and is optically so that the reflected light from the inner reflecting surface 27a of the reflecting mirror 27 is polarized so as to be converted into parallel rays and can be condensed and irradiated forward. Designed.

  On the other hand, as shown in FIG. 2, the outer reflecting surface 27b of the reflecting mirror 27 has a relative arrangement in which the high-intensity white LED 11 is positioned on the central axis spaced from the rear opening as shown in FIG. The light emitted from the high-intensity white LED 11 is formed on a curved surface that reflects the light toward the circumferential light-transmitting connection case 3.

  The reflecting mirror 27 is formed by setting the reflectance of the inner reflecting surface 27a to be low and the reflectance of the outer reflecting surface 27b to be high. In this embodiment, the inner reflecting surface 27a and the outer reflecting surface 27b are formed. However, it is formed with a predetermined reflectance by means such as polishing, but it can also be formed with a predetermined reflectance by a surface treatment means for depositing aluminum. The reflecting mirror 27 has a single or a plurality of heat radiation ports 27c.

  The translucent connecting case 3 is formed of a translucent synthetic resin colored in red in a cylindrical shape having a diameter on which the outer peripheral surface thereof slides with respect to the inner peripheral surfaces of the main body case 1 and the front case 2. Yes. Therefore, the portable LED lighting device is configured such that the light transmissive connecting case 3 slides in and out of the main body case 1 and the front case 2 slides in and out of the light transmissive connecting case 3. The main case 1, the light transmissive connecting case 3 and the front case 2 can be expanded and contracted by changing the relative positions in the central axis direction, so that the signal lamp mode and the headlamp You can switch to mode.

  Further, the light transmissive connecting case 3 is provided with a light transmissive portion 3a for diffusing and emitting the transmitted light at the central portion thereof, and a serrated surface 3b on the outer peripheral surface of both the front and rear sides with respect to the light transmissive portion 3a. Further, locking pieces 3c and 3d are formed at both front and rear ends.

  Next, a usage pattern of the portable LED lighting device will be described. First, when it is used as a signal lamp at a construction site or traffic control, as shown in FIG. 2, the light-transmitting connection case 3 is connected to the locking protrusion 7 a of the battery housing portion 7. The front case 2 is pulled out from the main body case 1 to the maximum drawing position where it abuts, and the front case 2 is connected to the light transmission connection to the maximum drawing position where the locking projection 29a of the fixing member 29 contacts the locking piece 3c of the light transmitting connection case 3. The device outer body is pulled out from the case 3 and extended to the maximum length.

  At this time, the light-transmitting connection case 3 has a pair of front and rear sawtooth portions 3b that are in pressure contact with the inner peripheral surfaces of the main body case 1 and the front case 2, respectively, It is held so that the position does not change to delusion. In this state, since the reflecting mirror 27 is separated from the high-intensity white LED 11, most of the light L emitted from the high-intensity white LED 11 is incident on the outer reflecting surface 27b of the reflecting mirror 27 and is transmitted through the side. The light is reflected toward the light transmission part 3a of the conductive connection case 3, passes through the light transmission part 3a, and is emitted to the side periphery as diffused light. Here, the high-intensity white LED 11 is used as a light source, and the outer reflection surface 27b of the reflecting mirror 27 is set to have a relatively large reflectance. A sufficient amount of light can be secured, and the light is converted into red light by being transmitted through the light transmitting portion 3a colored in red. Therefore, if the body case 1 is gripped in this state, the surrounding car It can be suitably used as a signal light to inform pedestrians of their presence and emergency.

  On the other hand, when used as a headlamp as required, as shown in FIG. 1, the light transmissive connecting case 3 is mounted on the main body until the light transmitting portion 3 a abuts the front opening end of the main body case 1. While being pushed into the case 1, the front case 2 is pushed in until the rear opening end of the front case 2 abuts on the light transmitting portion 3 a of the light transmissive connecting case 3 to be shortened to the minimum length.

  At this time, the light transmissive connecting case 3 has its own pair of front and rear sawtooth portions 3b in pressure contact with the inner peripheral surfaces of the main body case 1 and the front case 2, respectively. The relative position is securely held so as not to change. In this state, the high-intensity white LED 11 is held at a position where it enters the rear opening of the reflecting mirror 27, so that most of the light L emitted from the high-intensity white LED 11 is forwarded by the inner reflecting surface 27 a of the reflecting mirror 27. Are reflected toward the condenser lens 28 and emitted from the front opening of the front case 2.

  Here, in addition to the use of the high-intensity white LED 11 as the light source, the condenser lens 28 is polarized so as to convert the reflected light from the inner reflection surface 27a of the reflecting mirror 27 into parallel rays and collect the light forward. Since it is optically designed so that it can irradiate light, it is possible to irradiate the required illumination area in the front evenly without uneven illumination while ensuring a predetermined illuminance. Moreover, since the inner reflecting surface 27a of the reflecting mirror 27 is set to have a lower reflectance than the outer reflecting surface 27b, the light from the high-intensity white LED 11 is reduced to a necessary light amount and directed toward the condenser lens 28. Since the light is reflected, an unnecessary light ring-shaped illumination area is not formed around the illumination area corresponding to the light emitting portion of the high-intensity white LED 11 that is imaged and irradiated forward by the condenser lens 28, and is easy to see. It becomes lighting. Therefore, if the main body case 1 is gripped in this state, it can be suitably used as a headlamp.

  Moreover, in the said illuminating lamp apparatus, the mode detection switch 12 is mounted and provided in the 1st circuit board 13, and when this mode detection switch 12 is set to the state of the signal lamp function shown in FIG. When the operation piece 3e of the transmissive connection case 3 is separated and turned off, it is detected that the signal lamp mode is set, and when the headlamp function state shown in FIG. When the actuator 3e of the case 3 is pushed down by its operation piece 3e, it is detected that it is in the headlamp mode.

  FIG. 3 is a block diagram of the electric control system of the illumination lamp device of this embodiment. In the figure, when the mode detection switch 12 detects the signal lamp mode, the switching control circuit 30 controls the lighting switching circuit 31 based on the detection signal of the mode detection switch 12, thereby switching the lighting from the power supply circuit including the battery 9. The driving power is supplied only to the blinking lighting circuit 33 via the circuit 31, and the blinking lighting circuit 33 is switched so that the high-intensity white LED 11 blinks. Therefore, when used as a signal lamp, since a flashing light is emitted from the light transmitting portion 3a of the light transmissive connecting case 3 toward the outer periphery, a danger notification effect is added. Become.

  On the other hand, when the mode detection switch 12 detects the headlight mode, the switching control circuit 30 controls the lighting switching circuit 31 based on the detection signal of the mode detection switch 12 to switch the lighting from the power supply circuit including the battery 9. Driving power is supplied only to the continuous lighting circuit 34 via the circuit 31, and the continuous lighting circuit 34 is switched so as to continuously light up the high-intensity white LED 11. Therefore, when the entire device is shortened so that the headlight is switched from the signal lamp as necessary, the high-brightness white LED 11 is automatically switched so as to be continuously lit. And easy to use.

  In addition, in the illumination lamp device of this embodiment, a high luminance white LED 11 capable of flowing a large current can be used to secure a desired luminance and make the entire device compact, while generating a large amount of heat. The overheating caused by using the high-intensity white LED 11 can be surely prevented. That is, in the illuminating lamp device, the heat generated by the high-intensity white LED 11 transfers heat to the first circuit board 13 on which the wiring pattern is formed using a metal material having a high heat transfer coefficient, and effectively dissipates to the surroundings. In addition, the heat transmitted through the internal space of the reflecting mirror 27 is effectively radiated from the heat radiation port 27c of the reflecting mirror 27 to the external space. As a result, the illuminating lamp device can effectively dissipate heat with a simple heat dissipating means provided on the first circuit board 13 and the reflecting mirror 27 without separately providing a large heat dissipating means. The LED 11 can reliably prevent overheating due to heat generation and ensure a long life.

  The present invention connects the main body case and the front case so that the relative position can be changed via a light-transmitting connection case interposed therebetween, so that light from the light source is stored in the front case. It can be used as a signal lamp when it is reflected by the outer reflecting surface of the reflecting mirror and is emitted around the side through a light-transmitting connection case. In addition, if necessary, from a light source The portable LED illuminating lamp device that can be suitably used as a headlamp can be provided by reflecting the light of the light on the inner reflecting surface of the reflecting mirror and releasing it forward through the front case. .
