도 1은 본 발명 손전등의 전체적인 구성을 나타낸 것으로, 원통 형상의 금속제 케이스(10)와, 상기 케이스(10)에 결합되는 엘이디(50)를 가진 헤드(20)와, 상기 케이스(10)의 내측에 설치되어 건전지의 전원을 온, 오프 스위칭 시키는 스위치(30)를 구비한 손전등(40)에 있어서, 상기 헤드(20)의 반사판(21)내부에 다수의 지지부(22)를 통하여 별도의 내부 반사판(23)을 더 형성하여 상기 반사판(21)내측에 다수의 엘이디(50)를 삽입함과 함께 상기 내부 반사판(23)의 중심부에 하나의 엘이디(24)를 삽입하도록 구성된 것이다.Figure 1 shows the overall configuration of the flashlight of the present invention, a cylindrical metal case 10, a head 20 having an LED 50 coupled to the case 10, and the inside of the case 10 In the flashlight 40 having a switch 30 installed in the switch 30 for switching the power of the battery on and off, a separate internal reflector through a plurality of supports 22 inside the reflector 21 of the head 20 (23) is further formed to insert a plurality of LEDs 50 inside the reflecting plate 21 and to insert one LED 24 in the center of the inner reflecting plate 23.

또한, 상기 엘이디(24)(50)는 끝단부를 소정부분까지 완만한 라운드로 절삭하여 엘이디(24)(50)의 광이 중심으로 모아져 원거리까지 강하게 비춰질 수 있도록 구성된 것으로, 도면중 미설명 부호 60은 손전등의 뚜껑, 70은 헤드에 끼워지는 투명유리이다.In addition, the LEDs 24 and 50 are configured such that the light of the LEDs 24 and 50 is gathered to the center and strongly reflected to a long distance by cutting the end portion in a gentle round to a predetermined portion. The lid of the flashlight, 70 is transparent glass fitted to the head.

단, 상기 엘이디(50)는 그대로 사용하고, 상기 엘이디(24)만 끝단부를 소정부분까지 완만한 라운드로 절삭할 수도 있다.However, the LED 50 may be used as it is, and only the LED 24 may be cut in a gentle round to a predetermined end portion.

도 2는 본 발명의 반사판(21)을 확대 사시도, 도 3은 반사판(21)의 단면도, 도 4는 반사판(21)의 정면도를 나타낸 것으로, 원형 반사판(21)의 내부면에 다수의 지지부(22)를 형성하고, 상기 지지부(22)의 중심부에 내부 반사판(23)을 더 설치하여 구성된 것으로, 도면중 50은 반사판(21)내측에 삽입되는 엘이디이고, 24는 반사판(23)의 중심부에 삽입되는 엘이디이다.FIG. 2 is an enlarged perspective view of the reflector 21 of the present invention, FIG. 3 is a sectional view of the reflector 21, and FIG. 4 is a front view of the reflector 21. 22 is formed, and the inner reflection plate 23 is further installed at the center of the support part 22. In the drawing, 50 is an LED inserted into the reflection plate 21, and 24 is at the center of the reflection plate 23. The LED to be inserted.

이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.

본 발명의 손전등은 금속제 케이스(10)내에 스위치(30)를 가진 스위치 본체를 삽입 고정시킨 상태에서 금속제 케이스(10)내에 배터리를 삽입하고 뚜껑(60)을 닫으며, 스위치 본체에 형성된 구멍에 엘이디 기판의 단자를 끼우면 이들 단자가 스위치 본체에 삽입되어 전기적으로 통할 수 있도록 연결된다.The flashlight of the present invention inserts a battery into the metal case 10 and closes the lid 60 in a state in which the switch body having the switch 30 is inserted into the metal case 10, and the LED is inserted into a hole formed in the switch body. When the terminals of the board are inserted, these terminals are inserted into the switch main body so as to be electrically connected.

따라서, 상기 엘이디(50)들이 기판을 통하여 일체형으로 고정되는 한편, 상기 엘이디(50)의 단자들이 외측으로 인출되어 결국 하나의 전구를 형성하게 된다.Accordingly, the LEDs 50 are integrally fixed through the substrate, while the terminals of the LEDs 50 are drawn out to form one light bulb.

이렇게 결합되는 엘이디(50)들의 공통접점인 단자들을 스위치 본체의 구멍에 삽입하면 단자가 스위치 본체에 전기적으로 통할 수 있도록 접속된다.When the terminals, which are the common contacts of the LEDs 50 coupled to each other, are inserted into the holes of the switch body, the terminals are connected to be electrically connected to the switch body.

또한, 상기 엘이디(50)의 기판을 스위치본체에 결합시키고 헤드(20)를 결합시킨 상태에서 사용자가 스위치(30)를 온/오프시키면 배터리의 전원이 스위치 본체에 삽입된 단자들을 통하여 엘이디(50)쪽으로 인가되므로 엘이디(50)가 빛을 발하여 반사판과 투명유리(70)를 통하여 외부로 투사되므로 멀리까지 광을 비출 수 있는 손전등의 역할을 수행하게 된다.In addition, when the user connects the substrate of the LED 50 to the switch body and the head 20 is coupled to the user on / off the switch 30, the power of the battery is led through the terminals inserted into the switch body 50 Because it is applied toward the LED 50 emits light and is projected to the outside through the reflector and the transparent glass 70 serves to serve as a flashlight that can emit light to the far.

이때, 본 발명은 상기 반사판(21)의 중심부에 다수의 지지부(22)를 통하여 별도의 내부 반사판(23)이 설치되어 있어 도 4에 도시된 바와 같이 반사판(21)의 내측과 반사판(23)의 중심부에 각각 다수의 엘이디(50)와 엘이디(24)가 삽입된다.At this time, the present invention is provided with a separate inner reflector 23 through a plurality of support 22 in the center of the reflector 21, as shown in Figure 4 and the reflector 21 and the reflector 23 A plurality of LEDs 50 and LEDs 24 are inserted in the center of each.

따라서, 전원공급시 반사판(21)의 내측으로 삽입되는 엘이디(50)들이 빛을 발하게 됨과 함께 반사판(23)의 중심부에 삽입된 엘이디(24)도 빛을 발하게 되는데 상기 반사판(21)내측과 내부 반사판(23)중심에 삽입되는 엘이디(24)(50)들의 끝단부가 소정부분까지 약간 라운드로 절삭되어 있어 엘이디(24)(50)들이 광을 발할 때 광이 엘이디(24)(50)의 라운드 표면을 통하여 180°퍼진 후 내부 반사판(21)(23)을 통하여 반사되어 중심으로 모아진 상태에서 외부로 비춰지므로 광이 원거리까지 강하게 비춰 질 수 있는 것이다.Accordingly, the LEDs 50 inserted into the reflection plate 21 emit light when the power is supplied, and the LEDs 24 inserted into the center of the reflection plate 23 also emit light. The ends of the LEDs 24 and 50 inserted into the center of the reflector 23 are cut slightly to a predetermined portion so that the light is rounded by the LEDs 24 and 50 when the LEDs 24 and 50 emit light. After 180 ° spread through the surface is reflected through the inner reflecting plate 21, 23 is reflected to the outside in a state gathered to the center, the light can be strongly reflected to a long distance.

여기서, 상기 반사판(21)에 삽입되는 엘이디(50)들은 절삭하지 않고, 내부반사판(23)에 삽입되는 엘이디(24)만 끝단만 절삭하여 중심부의 광도를 향상시킬 수도 있다.Here, the LEDs 50 inserted into the reflector 21 may not be cut, and only the ends of the LEDs 24 inserted into the internal reflection plate 23 may be cut to improve the brightness of the center portion.

이상에서 상세히 설명한 바와 같은 본 발명은 손전등의 반사판 중심부분에 지지부를 통하여 반사판을 더 형성하고, 반사판내에 끝단부가 소정부분까지 절삭되어 광을 180°비출 수 있는 엘이디를 삽입하므로 엘이디의 광을 중심으로 모아서 원거리까지 강하게 비출 수 있는 효과가 있다.According to the present invention as described in detail above, the reflector is further formed in the central portion of the reflector of the flashlight through the support, and the LED is inserted into the reflector so that the end portion is cut to a predetermined portion to emit 180 ° of light. There is an effect that can be gathered strongly to a long distance.
