이하에서는 첨부된 도면을 참조로 하여 본 고안의 LED 형광등을 보다 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in more detail the LED fluorescent lamp of the present invention.

도 2는 본 고안에 따른 일 실시예의 LED 형광등의 사시도이며, 도 3은 본 고안에 따른 일 실시예의 LED 형광등의 분리 사시도이다.Figure 2 is a perspective view of the LED fluorescent lamp of one embodiment according to the present invention, Figure 3 is an exploded perspective view of the LED fluorescent lamp of an embodiment according to the present invention.

도 2에 도시된 바와 같이 본 고안에 따른 LED 형광등(100)은 바형 도광판(110), 및 바형 도광판(110)의 양단에 결합된 2개의 발광부(130)로 이루어지는바, 형광등갓(1)의 소켓(2)에 결합된다.As shown in FIG. 2, the LED fluorescent lamp 100 according to the present invention includes a bar light guide plate 110 and two light emitting parts 130 coupled to both ends of the bar light guide plate 110. Is coupled to the socket (2).

전술한 구성에서 소켓(2)이 결합된 형광등갓(1)은 통상적인 형광등갓으로 달성되는바, 내면에는 형광등에서 발산되는 빛을 반사시키기 위해 반사면(4)이 형성되며, 소켓(2)은 외부로부터 전달된 전력을 LED 형광등(100)으로 전달하기 위한 단자 삽입공(3)이 형성되어 있다.In the above-described configuration, the fluorescent lampshade 1 to which the socket 2 is coupled is achieved by a conventional fluorescent lampshade, and a reflection surface 4 is formed on the inner surface to reflect light emitted from the fluorescent lamp, and the socket 2 The terminal insertion hole 3 for transmitting the power transmitted from the outside to the LED fluorescent lamp 100 is formed.

따라서 본 고안에 따른 LED 형광등(100)은 발광부(130)에 구비된 단자(133a)가 소켓(2)의 단자 삽입공(3)에 삽입됨으로써 발광 전력을 공급받는다.Therefore, the LED fluorescent lamp 100 according to the present invention receives light emitting power by being inserted into the terminal insertion hole 3 of the socket 2 with the terminal 133a provided in the light emitting unit 130.

When coupled to the fluorescent lamp shade (1), the power supplied to the fluorescent lamp shade (1) is transmitted to the terminal 133a of the LED fluorescent lamp 100 through the terminal insertion hole (3) of the socket (2), and then the circuit board ( Power is transmitted to the LED 135 connected to the terminal 133a through the 133 to emit the LED 135. The emitted light of the LED 135 is formed through the lens 137 of the bar light guide plate 110. After entering the incident surface, the bar light guide plate 110 emits light.

즉, 본 고안에 따른 LED 형광등(100)은 종래 형광등에 비하여 보다 적은 개수의 LED(135)가 이용되는바, LED(135)에서 발광된 빛은 렌즈(137)를 통과하면서 보다 밝은 빛으로 바뀌게 되며, 보다 밝은 빛을 입사 받은 바형 도광판(110)은 면 전체에 균일한 빛을 발산하게 되어 결국 본 고안에 따른 LED 형광등(100)은 종래 LED 형광등에 비하여 보다 밝고 균일한 빛을 발산하게 된다.That is, the LED fluorescent lamp 100 according to the present invention uses fewer LEDs 135 than the conventional fluorescent bar, and the light emitted from the LED 135 is changed into brighter light while passing through the lens 137. The light guide plate 110 that receives brighter light emits uniform light on the entire surface, and thus, the LED fluorescent light 100 according to the present invention emits brighter and more uniform light than the conventional LED fluorescent light.
