In addition, the lower end of the vertical portion 111 may be attached to the hook for hanging the flash itself on the fixture such as nails.

The horizontal part 112 is a part extending in the vertical direction from one end of the vertical part 111. The horizontal portion 112 is coupled to a portion capable of performing a fresh function including a light emitting body that actually emits light.

In the present invention, the thermal barrier wall 113 is provided between the horizontal portion 112 and the vertical portion 111, the PCB 122 is inserted into the horizontal portion 112 from the battery inserted into the vertical portion 111 It protects against heat generated.

Case in the present invention can be made of a variety of materials, in consideration of corrosion resistance and resistance to external impact is preferably made of plastic or aluminum.

The light emitter 120 has one end inserted into the horizontal portion 112 and the other end inserted into the zoom adjuster 150 to be described later. In order to prevent the light emitting unit 120 from being received in the horizontal unit 112 and to prevent the flow of light, the light emitting unit 120 is preferably formed in the same shape as the cross section of the horizontal unit 112. Generally, It is preferable to make also cylindrical shape.

The PCB 122 is installed at the end of the portion inserted into the horizontal portion 112 of the light emitter 120, and the LED 121 is attached to the other end.

In the present invention, the light source attached to the light emitter 120 uses the LED 121 rather than the filament bulb. This is because the LED has a semi-permanent lifetime and requires little replacement or maintenance when installed once. It consumes 1 / 10th of the bulb and 1/2 of the fluorescent lamp, so it has a large energy saving effect and can be made compact, thin and lightweight. , Discharge gas, and the like. Therefore, since the light emitted from the LED is strong in a straight line, it is suitable for application to the flash according to the present invention.

In the conventional flash as shown in FIG. 1, the PCB 122 is directly attached to the LED 121, so that the PCB 122 may fail or malfunction due to the heat generated by the LED 121. In the present invention, In order to solve this problem, the light emitting unit 120 is required to be at least 1.5 cm in length, and the material thereof is made of a plastic which is not easily transmitted through heat. A PCB 122 is attached to one end of the luminous body 120 and an LED 121 is attached to the other end so that the distance between the LED 121 and the PCB 122 is 1.5 cm or more. As a result, the heat generated from the LED 121 does not affect the PCB 122. Here 1.5Cm is the minimum distance in consideration of the material of the plastic and the amount of heat generated from the LED (121).

On the other hand, a spring 123 for use as a contact point for electrical connection protrudes from the center of the PCB 122 of the light emitter 120. The parts used for electrical connection in the present invention may be applied to those used in a conventional flash, and a detailed description thereof will be omitted.

The zoom regulator 150 is a portion surrounding one end of the light emitter 120, which has a hollow cylindrical shape. Since the zoom adjusting body 150 has to be coupled to the horizontal portion 112 at one end, it is preferable that the zoom adjusting body 150 is formed in the same shape as the horizontal portion 112. Therefore, if the horizontal portion 112 is cylindrical, the zoom regulator 150 is also manufactured in a cylindrical shape. The zoom adjuster 150 has one end coupled to the horizontal portion 112 and the middle portion contacting the rim portion 124 of the light emitter 120. The zoom adjuster 150 includes a lens 130 in front thereof and a lens cover 140) is inserted.

The zoom adjuster 150 can be moved forward or backward by sliding or screwing the horizontal portion 112. This causes the lens 130 coupled to the inside of the zoom adjuster 150 to move along the LED 121, By sliding forward and backward relative to the reference, the light emitted from the LED 121 can be spread over a wide range or collected in a narrow range. This is described in detail in the lens section.

In order to perform this function, the zoom adjuster 150 is formed with two steps 151 and 152 therein so that the inner diameter of the zoom adjuster 150 can be gradually decreased from the rear of the zoom adjuster 150 to the front.

4 (a), the rotation of the zoom adjusting body 150 is limited by the supporting step 114 formed on the outside of the horizontal part 112, and the rotation of the zoom adjusting body 150 As shown in FIG. 4 (b), the rearward step 151 is restricted by the rim 124 of the light emitter 120 having a larger diameter than that of the rearward step. That is, the rear step 151 serves to limit the range of rotational movement using the sliding or screw line of the zoom control body 150.

The lens 130 is engaged with the front step 152 and the lens 130 is made to have a diameter enough to be caught by the front step 152 and unable to move backward.

The lens cover 140 is inserted into the zoom adjuster 150 while being coupled to the inside of the front of the zoom adjuster 150 so as to prevent the lens 130 caught in the front step 152 from falling forward It serves to fix.

The lens 130 is used to spread the light emitted from the LED 121 evenly over a large area at a relatively short distance or to illuminate a small area at a relatively long distance. To this end, the lens 130 of the present invention uses a convex lens. In particular, in the present invention, it is preferable to use a special lens made by precision processing instead of a general convex lens. As a result, the light can be clearly transmitted without being distorted by the lens while sending light farther than the distance of the existing lens.

On the other hand, the fresh lens 100 is attached to the special lens according to the present invention may be additionally attached to the filter cylinder 160 to the lower end of the vertical portion (111). The filter is inserted into the front of the lens 130 is additionally fixed by the lens cover 140, the filter 161 has a variety of colors or figures or patterns are displayed, the larger the flash in the attached state The colors, patterns, figures, and the like displayed on the filter 161 are reflected. This can be useful when performing special missions such as military operations or lifesaving.

The filter cylinder 160 may be installed under the vertical portion 111, and various filters 161 may be stored therein.

In addition, the clasp 170 may be additionally attached to the outside of the vertical portion 111. The clasp 170 is used to temporarily fasten the flash to clothes or peninsula. When the clasp 170 is attached to the body by using the clasp 170, the light is only shining forward, and the front of the situation moves or moves forward. This can be useful when sending a signal.

Next, the operation of the flash according to the present invention will be described.

The flash according to the present invention can adjust the distance between the light emitting unit 120 and the lens 130 by using the zoom adjusting unit 150, thereby spreading the light widely or concentrating it in one place.

5 is a view for explaining the operation of the flash according to the present invention.

FIG. 5 (a) shows the case where the zoom adjuster 150 moves rearward and the distance between the lens 130 and the light emitter 120 is close. In this case, the light diffuser 150 maximizes the light diffusion and evenly illuminates a wide area. Used.

5B shows a case where the distance between the lens 130 and the light emitter 120 is maximized when the zoom adjuster 150 moves forward, maximizing the straightness of the light and transmitting the light to a long distance. In particular, since only straight light is generated without ambient light, it shows superior straightness as compared to the conventional flash.

In addition, the flash according to the present invention can mount various filters 161 and can transmit a signal to a long distance by using the zoom adjusting body 150 in the state that various filters are mounted, It can be used for special purpose.

In addition, the present invention has a variety of means for protecting the PCB 122 from heat, thereby improving the problems that occur in conventional fresh products. That is, in the present invention, the battery contact point 117, which generates the most heat, is positioned in the vertical portion 111, the PCB 122 circuit is installed in the horizontal portion 112, and the horizontal portion 112 and the vertical portion A heat shield wall 113 is provided on the PCB 111 so that the heat generated at the battery contact 117 does not directly affect the PCB 122 so that the PCB 122 is not located at the upper portion of the battery contact 117 It was.

Next, in order to prevent the heat generated by the LED 121 from affecting the PCB 122, the light emitting unit 120 having a length of at least 1.5 cm is used to adjust the physical length of the LED 121 and the PCB 122 The light emitter 120 itself was made of a material having low thermal conductivity.
