Next, the operation and effects of the shadow-free portable emergency light between 2cm in front and 20cm focus according to an embodiment of the present invention configured as described above will be described.

First, by placing the lower surface of the cradle 110 on the wall, tightening the screw 114 through the bolt hole 113 formed in the cradle 110, the cradle 110 is installed on the wall, the cradle 110 When the protrusion 111 installed perpendicular to the middle portion of the lower housing 101 is inserted into the through hole 101a formed in the middle portion of the lower housing 101, the protrusion 106 integrally formed in the lower housing 101 is mounted on the holder 110. Since it is inserted into the recessed groove 112 formed in the), the lower housing 101 and the upper housing 108 around the holder 110 is fixed to the holder 110 without being rotated.

At this time, the + electrode contact terminal 111a disposed on one side (right side in FIG. 7) of the protrusion 112 installed in the holder 110 is electrically connected to the + electrode of the battery 90, and the protrusion 112 is disposed. Since the contact terminal 111b for the electrode disposed on the other side (left side in FIG. 7) is electrically connected to the negative electrode of the battery 90, power is applied to the light emitting diode 120 so that the battery 90 ) Is charged and the gap between the two batteries 90 disposed in the space formed by the lower housing 101 and the upper housing 108 by the protrusion 112 made of an insulating material. The two batteries are electrically in contact with each other so that no power is applied to the lamp 92, and thus the light does not emit.

As such, when the emergency lighting is coupled to the cradle 110 while the lower housing 101 and the upper housing 108 are fixed to the cradle 110, or when the surroundings are dark, the lower housing 101 installed on the cradle 110 and When the portable emergency lamp with the upper housing 108 is pulled out, the negative electrode of one battery 90 inserted between the batteries 90 is in electrical contact with the positive electrode of the other battery 90. The plate spring 130 in which the + electrode of the battery is disposed on the fixing bracket 103 of the lower housing 101 is in electrical contact. Accordingly, + power is supplied to the + electrode of the lamp 92. The coil spring 140 is installed in the space 104a formed inside the rear partition plate 140 of the lower housing 101 to be in electrical contact, and the second coil is in electrical contact with the first coil spring 140. The lamp 9 through the coil spring 150 Since 2) is grounded, the lamp 92 emits light to illuminate the front.

At this time, since the minute uneven surface is formed on the reflective surface of the reflecting plate 160 provided around the lamp 92 by sand blast, the light emitted from the lamp 92 is diffusely reflected by the reflecting plate 160 The light diffused by the reflection plate 160 is focused by the protection plate 170 made of a convex lens, and passes through a plurality of concave grooves 172 of concave shape formed in the protection plate 170, and is 2 m forward.

On the other hand, when the portable emergency lighting lamp coupled to the lower housing 101 and the upper housing 108 installed on the holder 110 is pulled out, since the power is not applied to the light emitting diodes 120, the light emitting device 120 is not lighted. Although the portable emergency lighting lamp, in which the lower housing 101 and the upper housing 108 are fixed to the holder 110, is installed, when the light emitting diode 120 does not emit light, the power charged in the battery 90 is Since all of the discharged state is indicated, the battery 90 must be replaced. However, if the light emitting diode 120 does not emit light even though the battery 90 is replaced, the light emitting diode 120 is a defective product, and thus the light emitting diode 120 should be replaced.

When the battery 90, the lamp 92, the reflector 160, or the leaf spring 130 is to be replaced, the fixing bolt 180 is coupled to the lower housing 101 and the upper housing 108. When the lower housing 101 is pushed out toward the proximal end of the upper housing 108, the coupling state of the lower housing 101 and the upper housing 108 can be released, so that the battery 90 and the lamp 92 ), The reflective plate 160 or the leaf spring 130 can be replaced.

The portable emergency light of the present invention is electrically connected to the coil spring 104 for one side in a circular bracket 105 integrally formed at the front of the body case 100 to maintain the elastic force of the leaf spring 130 for a long time. Since the second coil spring 150 for contacting and the other side (coil portion 150a) is externally wound around the electrode portion of the lamp 92 and elastically supports the lamp 92 is inserted and fixed, The lamp 92 is always elastically supported by the coil part of the second coil spring 150 to maintain the elastic force of the leaf spring 130 for a long time.

In the above description, the portable emergency lighting lamp coupled to the lower housing 101 and the upper housing 108 has been described as an example, but the present invention is not limited thereto. For example, a cylindrical handle portion having a push switch is installed. And a cover part coupled to the tip of the handle part, a reflecting plate installed in the cover part to reflect light emitted from the lamp, and a protective plate made of a transparent material protecting the reflecting plate and the lamp (flashlight). In the), even if the portable emergency light (flashlight) having a fine concavo-convex surface formed on the reflective surface of the reflecting plate and a plurality of concentric grooves on the transparent protective plate is turned on, the appearance of a shadow is prevented between 20 cm focus from 2 m. Of course, it is possible to brighten the illumination area, these technical ideas are also included in the concept of the present invention.

In addition, even if you turn on a portable emergency light (flashlight) formed by forming a fine concave-convex surface on the reflecting plate of the reflector installed on the lantern and a plurality of concentric grooves on the transparent protection plate, it prevents the appearance of a shadow between 20 cm and 20 cm focal points. Of course, the lighting area can be brightened, and these technical ideas are also included in the concept of the present invention.

In the above description, although illustrated and described with reference to specific embodiments, the present invention is not limited to this, for example, by those of ordinary skill in the art without departing from the concept of the present invention Of course, the design can be changed in various ways.

As described above, according to the portable emergency light of the present invention, an inverted V-shaped plate spring is secured to the fixed bracket integrally formed inside the front partition plate of the lower housing of the main body case so as to be in electrical contact with the + electrode of the battery. The first coil spring for the electrode is inserted and fixed in the space formed inside the partition plate behind the lower housing of the main body case to be in electrical contact with the electrode of the battery, and to diffuse the light emitted from the lamp toward the front. Concave-convex surface is formed on the reflecting surface of the funnel-shaped reflecting plate, and a protective plate made of a transparent body is disposed on the front surface of the reflecting plate so that the diffused light on the reflecting surface of the reflecting plate prevents the appearance of shadows between 20 cm and 20 cm focal points. A plurality of concentric grooves are formed on the inner side on the inner side to extend the elastic force of the leaf spring. One side is in electrical contact with the coil spring for the electrode, and the other side (coil part) is wound around the -electrode part of the lamp in the circular bracket integrally formed at the front of the front partition plate of the main body case to hold the lamp. Since the second coil spring for sexually supporting -electrode is inserted and fixed, when the main body case is pulled out from the cradle, the two batteries are electrically connected to each other to supply power to the lamp and emit light. Diffuse reflection is reflected on the reflecting surface of the uneven surface, and the diffusely reflected light generates a black circular shadow between the 20cm focal points when illuminating the subject (or wall) 2m in front of the groove formed inside the protective plate.
