Description

Hanger type Lantern}

The present invention relates to a hanging lantern, and more particularly, to a two-light source using a light emitting diode and to a light type for long distance irradiation and a hanging lantern that can combine bright room lighting without glare.

In general, lanterns are used for portable lighting at night when there are no lights. Typically there is a hand lantern with a handle and a head lantern attached to the headband. When such a lantern is used for indoor lighting, it is inconvenient to use due to severe glare by a powerful light beam. In particular, when using a lantern outside a tent in the field, it is very good when a long distance is projected by a powerful light beam, but when it is lit inside a tent, it is difficult to illuminate a room because a strong light beam is projected on a narrow space.

Utility Model Registration No. 332243 discloses a portable flashlight having a general filament lamp for main lighting and a light emitting diode for auxiliary lighting. In this design, one lamp is installed at the center and three light emitting diodes are arranged on the parabolic surface of the lamp, and only the light emitting diode is lit inside the tent.

However, in the conventional design, since only the light emitting diodes are lit instead of the lamp inside the tent, the glare can be relatively reduced compared to the lighting of the lamp, but the glare is still eliminated by the direct light by the light emitting diodes, so the inconvenience of use is not completely eliminated. In addition, since the light emitting diodes are installed on the parabolic surface, the amount of light reflected from the parabolic surface during casting is reduced, thereby reducing the brightness. Therefore, the number of light emitting diodes was limited to three in order to maintain the lighting in the tent while minimizing the decrease of the brightness in the long distance lighting. Therefore, it was not possible to provide enough brightness in the tent.

An object of the present invention for solving the above problems is to provide a lantern for a hanger that can satisfy both long-range and indoor lighting at the same time.

Another object of the present invention is to provide a hanging lantern that can be indirect lighting without glare while very bright room lighting.

The diameter of the disc 142 is sized so that the edge is supported on the inner step 122-3 of the tip 122-1 of the upper tube 122. The outer diameter of the small tube 144 is smaller than the inner diameter of the lower tube 124 and the inner diameter is larger than the outer diameter of the battery holder. A central groove 142-1 is formed at the center of the front surface of the disc 142, and three protruding cylinders 142-2 are formed at equal intervals on the concentric circles around the disc 142. The center groove 142-1 is provided as a space for accommodating circuit components and connecting wires. Three screw holes 142-3 are formed at the edges of the disc 142 at equal intervals.

A long hole 144-3 is formed on the outer circumferential surface of the disc 142 and communicates with the space 144-1. One end of the positive electrode conductor piece 150 is fixed to the rear surface of the disc 142 surrounded by the small tube 144 by riveting. The other end of the positive electrode conductor piece 150 is drawn out and bent into the long hole 144-3, and then exposed to the front surface of the disc 142.

One end of the negative electrode conductor piece 160 is bent to the front surface of the disk and the other end is bent to the rear surface of the disk 142 and mounted to the mounting groove 142-5 from the edge of the disk 142.

Three parabolic grooves 182-1 are formed on the front surface of the reflective tube 182 in an equilateral triangle, and through holes 182-2 are formed at the bottom of the parabolic groove 182-1. Three light emitting diodes LED1 to LED3 disposed in the center of the substrate 170 are inserted into the through hole 182-2. The parabolic grooves 182-1 reflect the light emitted from the light emitting diode to the front in a long distance with parallel light. The reflective visor 184 is provided with through holes 184-1 corresponding to nine light emitting diodes LED4 to LED12, respectively. Three threaded holes 184-2 are formed in the reflective visor 184 to coincide with the threaded holes 172 of the circuit board 170. The outer circumferential surface of the reflective tube 182 is also coated with an aluminum film and provided as a reflective surface. Therefore, the light emitted from the nine light emitting diodes installed in the reflective visor 184 is reflected from the outer circumferential surface of the reflective tube 182 and diffusely reflected in all directions to form a very bright illumination light without glare by the translucent inner cap.

The switch 190 includes a rectangular switch substrate 192, a push switch 194 and an elastic cap 196.

The protrusions 222-2 and 224-2 are sized to be inserted into the position grooves 212-2 and 214-2. Rotating grooves 226 and 228 are provided on the outer circumferential surfaces of both ends of the C-shaped plastic handle 220. Rotating grooves 226 and 228 restrict the C-shaped elastic body 230 to be rotated from the C-shaped plastic handle 220 within a predetermined angle range, for example, about 60 degrees. The end of is formed with an inclined surface that increases as it moves away from the initial position, and a locking groove is formed at the furthest position, and the C-shaped elastic member 230 is caught in the locking groove so as not to return to the initial position. If it is over, it is restored to the initial position by the elastic force of the C-type elastic body 230. Both ends cover (227, 229) is coupled to both ends in a concave structure to secure the C-type elastic body 230 is not separated from the shaft hole.

C-type elastic body 230 is a steel wire bent in a C-shape one end is inserted into the through hole (212-1), the other end is inserted into the through hole (214-1) is provided as a rotating shaft of the handle 200.

The negative electrode of the battery holder is in contact with the spring 132 of the rear cap 130, and the plus electrode is in contact with one end of the positive electrode conductor piece 150 of the insulating inner cylinder 140.

Therefore, the current path is the battery holder plus electrode-plus electrode conductor piece 150-circuit board-light emitting diode anode electrode-light emitting diode cathode electrode-drive circuit 174-switch-negative electrode conductor piece 160-upper metal tube (122)-lower metal tube (124)-trailing cap (130)-spring (132)-battery holder minus electrodes.

8 shows a circuit diagram of a preferred embodiment of the drive circuit of the present invention. Referring to FIG. 5, the driving circuit 172 includes a capacitor C1, an integrated circuit IC1, and transistors Q1 and Q2. The integrated circuit IC1 controls the outputs S1 and S2 whenever the switching pulse of the switch 190 is input. That is, the output signals S1 and S2 are sequentially controlled in the order of the direct lighting on mode, the indirect lighting on mode, and the off mode. When the first switching pulse signal is input, the transistor Q1 is turned on by keeping the S1 signal high. Therefore, only the light emitting diodes LED1 to LED3 disposed in the center are turned on. When the next switching pulse signal is input, the S1 signal is turned low and the S2 signal is kept high to turn on the transistor Q2. Accordingly, only the light emitting diodes LED4 to LED12 disposed in the vicinity thereof are turned on. When the next switching pulse signal is input, both the S1 and S2 signals are kept low and remain off.
