이와 같이 구성된 본 발명의 작용을 상세히 설명한다.The operation of the present invention configured as described above will be described in detail.

본 발명의 손전등은 먼저, 금속제 케이스(10)내에 스위치(30)를 가진 스위치 본체(31)를 삽입 고정시킨 상태에서 금속제 케이스(10)내에 배터리를 삽입하고 뚜껑(60)을 닫고, 전구케이스(50)를 스위치 본체(31)에 끼운다.The flashlight of the present invention first inserts a battery into the metal case 10 and closes the lid 60 in a state in which the switch body 31 having the switch 30 is inserted into the metal case 10, and the lid 60 is closed. 50) to the switch body (31).

즉, 스위치본체(31)에 탄설된 스프링(32)부분에 전구케이스(50)를 끼우면 전구케이스(50)의 중심부에 돌출된 (+)단자(52)가 스프링(32)에 접촉됨과 아울러 헤드(20)의 내측에 끼워지는 원형 링(55)이 (-)단자 역할을 하게 된다.That is, when the bulb case 50 is inserted into the spring 32 portion of the switch body 31, the positive terminal 52 protruding from the center of the bulb case 50 contacts the spring 32 and the head. A circular ring 55 fitted inside the 20 serves as a negative terminal.

이때, 상기 기판(53)에는 다수의 엘이디(51)가 삽입 고정되는데 외측으로 고정된 엘이디(51)들의 일측 단자들은 기판(53)의 제1납땜라인(A)을 통하여 공통 접속되고, 타측 단자들은 기판(53)의 제2납땜라인(B)을 통하여 공통 접속된다.In this case, a plurality of LEDs 51 are inserted into and fixed to the substrate 53, and terminals of one side of the LEDs 51 fixed to the outside are commonly connected through the first soldering line A of the substrate 53, and the other terminal. They are commonly connected via the second soldering line B of the substrate 53.

또한, 내측으로 고정된 엘이디(51)들의 일측 단자들은 기판(53)의 제3납땜라인(C)을 통하여 공통 접속되고, 타측 단자들은 기판(53)의 제4납땜라인(D)을 통하여 공통 접속된다.In addition, one terminals of the LEDs 51 fixed inward are commonly connected through the third soldering line C of the substrate 53, and the other terminals are common through the fourth soldering line D of the substrate 53. Connected.

따라서, 상기 엘이디(51)들이 원형의 기판(53)에 일체형으로 고정되는 한편, 상기 엘이디(51)의 단자들이 납땜라인(A∼D)을 통해 공통 접속된다.Thus, the LEDs 51 are integrally fixed to the circular substrate 53, while the terminals of the LEDs 51 are commonly connected through the solder lines A to D.

즉, 제1납땜라인(A)과 제3납땜라인(C)이 하나로 공통 접속되고, 제2납땜라인(B)과 제4납땜라인(D)이 하나로 공통 접속되는데 이때, 제2납땜라인(B)과 제4납땜라인(D)은 중심부의 돌출부를 통하여 (+)단자(52)가 되고, 제1납땜라인(A)에는 원형 링(55)이 설치되어 이 원형 링(55)이 (-)단자역할을 하게 된다.That is, the first soldering line A and the third soldering line C are commonly connected to one, and the second soldering line B and the fourth soldering line D are commonly connected to one. B) and the fourth soldering line D become the (+) terminal 52 through the protruding portion of the center portion, and the first soldering line A is provided with a circular ring 55 so that the circular ring 55 is ( It will play the role of terminal.

한편, 상기 다수의 엘이디(51)들이 고정된 기판(53)을 원형 결합부(56)에 끼우고 원형 결합부(56)의 내측으로 원형 링(55)을 끼워 이 원형 링(55)이 원형 결합부(56)의 가장자리에 위치되게 한 상태에서 전구 케이스(50)를 스위치본체(31)에 결합시키면 전구케이스(50)의 중심부에 돌출된 (+)단자(52)부분이 스위치 본체(31)의 스프링(32)에 접촉됨과 동시에 링(55)이 케이스(10)에 접촉된다.Meanwhile, the circular ring 55 is circular by inserting the substrate 53 on which the plurality of LEDs 51 are fixed to the circular coupling portion 56 and inserting the circular ring 55 into the circular coupling portion 56. When the light bulb case 50 is coupled to the switch body 31 in a state where it is positioned at the edge of the coupling part 56, a portion of the positive terminal 52 protruding from the center of the light bulb case 50 is switched by the switch body 31. The ring 55 is in contact with the case 10 while being in contact with the spring (32) of.

여기서, 상기 원형링(55)은 (-)단자의 역할을 함과 함께 원형 결합부(56)의 가장자리에 견고하게 결합되어 전구케이스(50)가 흔들리지 않도록 잡아주는 역할을 하게 되는 것으로, 일측이 개구되어 있어 원형 결합부(56)에 탄력적으로 착탈 가능하도록 이루어져 있다.Here, the circular ring 55 is to serve as a (-) terminal and to be firmly coupled to the edge of the circular coupling portion 56 to hold the bulb case 50 so as not to shake, one side is The opening is made to be elastically detachable to the circular coupling portion 56.

다음에 반사경(70)과 투명유리(80)가 결합된 헤드(20)를 케이스(10)에 결합시키면 나사부에 의해 헤드(20)가 케이스(10)에 견고히 결합되어 하나의 손전등이 되는 것이다.Next, when the head 20 combined with the reflector 70 and the transparent glass 80 is coupled to the case 10, the head 20 is firmly coupled to the case 10 by a screw part, thereby becoming a flashlight.

이와 같이 손전등이 결합된 상태에서 사용자가 스위치(30)를 온시키면 케이스(10)내에 내장된 배터리의 (+)전류는 스위치 본체(31)의 스프링(32)을 통하여 전구케이스(50)의 (+)단자(52)로 인가됨과 동시에 배터리의 (-)전류는 케이스(10)를 통하여 링(55)에 인가되므로 이 링(55)과 접촉된 제1납땝라인(A)을 통하여 (-)전류가 인가되어 엘이디(51)들이 빛을 발생하게 되므로 반사경(70)과 투명유리(80)를 통하여 투사되는 것이다.When the user turns on the switch 30 in the state where the flashlight is coupled as described above, the positive current of the battery built in the case 10 is transferred to the bulb case 50 through the spring 32 of the switch body 31. The negative current of the battery is applied to the ring 55 through the case 10, and is applied to the ring 55 through the first lead line A in contact with the ring 55. Since the current is applied to the LEDs 51 to generate light is projected through the reflector 70 and the transparent glass 80.

이상에서 상세히 설명한 바와 같은 본 발명은 다수의 엘이디를 하나의 원형기판에 삽입하여 일체형으로 구성하고, 상기 엘이디들의 (+)단자와 (-)단자를 납땜라인을 통하여 각각 공통 접속함과 함께 납땜라인의 가장자리에 원형 링을 고정시킴으로써 (-)단자의 역할과 전구케이스의 흔들림 방지 역할을 동시에 수행할 수 있는 효과가 있다.According to the present invention as described in detail above, a plurality of LEDs are inserted into one circular substrate to be integrated, and the (+) terminal and the (-) terminal of the LEDs are connected to each other through a soldering line and a soldering line. By fixing the circular ring on the edge of the (-) terminal and the effect of preventing the shake of the bulb case can be performed at the same time.
