본 고안은 평판형 냉음극 형광램프에 관한 것으로, 보다 상세하게는 하판유리 판넬에 요철부를 형성하여 발광면적을 넓혀줌으로써 휘도를 증가시키고, 상기 판넬의 외측면에 다는 반사판대신 알루미늄을 코팅하여 반사판 역할을 하도록 함으로써 종래의 반사판을 제외한 만큼의 박형화를 기할 수 있는 평판형 냉음극 형광램프에 관한 것이다.The present invention relates to a flat plate cold cathode fluorescent lamp, and more specifically, to increase the luminance by forming an uneven portion in the lower glass panel to increase the light emitting area, and to coat the aluminum on the outer surface of the panel instead of the reflector to act as a reflecting plate The present invention relates to a flat plate cold cathode fluorescent lamp capable of reducing the thickness of the conventional reflector plate.
종래의 평판형 냉음극 형광램프는, 제2도에 도시한 측면도와 같이 상판 유리판넬(1)과 이와 동형의 평판형하판유리 판넬(2)을 일정간격을 두고 서로 상, 하로 적층시킨 사이에 방전공간과 함께 양측으로 방전전극(3)(3')을 형성하고, 상기 방전공간내에는 방전을 원활히 일어나게 해주면서 수은 또한 안정화시켜주는 아르곤가스를 충전함과 더불어 상기 방전공간(4)으로 부터는 구동전압이 인가되는 방전전극(3)(3')과 아르곤 가스주입전방전공간을 전공시켜 주기 위해 가스를 배출하는 배기관(5) 및 상기 상,하판 유리판넬(1)(2)의 내표면에 형광면(6) (7)을 적당한 두께로 형성시켰다.In the conventional flat cold cathode fluorescent lamp, the top glass panel 1 and the same flat plate bottom glass panel 2 of the same type are laminated up and down with a predetermined interval as shown in the side view shown in FIG. Discharge electrodes 3 and 3 'are formed on both sides together with the discharge space, and the discharge space is charged from the discharge space 4 while charging the argon gas which stabilizes the mercury and stabilizes the discharge. On the inner surface of the exhaust pipe (5) and the upper and lower glass panels (1) and (2) which discharge gas in order to discharge the discharge electrodes (3'3 ') and the argon gas injection discharge space to which voltage is applied. Fluorescent surfaces 6 and 7 were formed to a suitable thickness.
그러나, 이와같이 형성된 종래의 평판형 냉음극 형광램프는 제4도 (a) (b)에 도시한 바와같이, 수은의 여기하에서 빛이 발광될때 하판 유리판넬(2) 측으로 일부 빛이 손실될뿐 아니라, 형광변(6)(7)의 발광면적도 S=L·a 만큼만 발광하기 때문에 면적당 빛손실률을 감안할때 형광램프가 커지면 커질수록 휘도가 경감되는 문제점이 있었다.However, in the conventional flat cold cathode fluorescent lamp thus formed, as shown in Fig. 4 (a) and (b), not only part of the light is lost to the lower glass panel 2 when light is emitted under excitation of mercury. Since the light emitting area of the fluorescent edges 6 and 7 also emits light only by S = L · a, in view of the light loss ratio per area, the larger the fluorescent lamp, the lower the luminance.
따라서, 본 고안은 상기한 종래의 문제점을 해소하기 위하여 안출된 것으로서, 그 목적은, 수은의 여기하에서 빛이 발광될때 손실되는 빛을 줄임과 동시에 발광면적을 넓혀 그에 따른 휘도를 증가시지며, 아울리 반사판을 제외한 만큼의 박형화를 기할 수 있는 평판형 냉음극 형광램프를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of which is to reduce the light lost when the light is emitted under the excitation of mercury and at the same time to increase the luminance by increasing the light emitting area, It is to provide a flat-type cold cathode fluorescent lamp that can be thinned as much as excluding the Woolly reflector.
상기 목적을 달성하기 위한 수단으로 본 고안의 평관형 냉음극 형광램프는 평판형으로된 상. 하판 유리판넬(1) (2)의 내표면에 형광면(6)(7)을 각각으로 형성시킨 통상의 냉음극 형광램프에 있어서, 상기 하판 유리판넬(2)의 내표면을 일정간격의 요철부(10)로 형성하고, 그 외면에는 반사 코팅막(15)을 형성시킨 것을 특징으로한다.The flat tubular cold cathode fluorescent lamp of the present invention as a means for achieving the above object is a flat plate. In a typical cold cathode fluorescent lamp in which fluorescent surfaces 6 and 7 are formed on inner surfaces of lower glass panels 1 and 2, the inner surface of the lower glass panel 2 is provided with irregularities at regular intervals. And a reflective coating film 15 formed on the outer surface thereof.
이하, 첨부된 도면을 참조하여 본 고안의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
즉, 제1도는 본 고안에 의한 평판형 냉음극 형광램프의 평면도 및 단면도를 도시한 것이다.That is, Figure 1 shows a plan view and a cross-sectional view of a flat plate cold cathode fluorescent lamp according to the present invention.
동도면에서의 (1)(2)는 상,하판 유리판네리며,(10)은 하판 유리판넬(2)의 내표면에 형성된 다수의 요철부이다.In the same drawing, (1) and (2) are upper and lower glass panels, and 10 is a plurality of uneven parts formed on the inner surface of the lower glass panel 2.
상기 요철부(10)는 하판 유리판넬(2) 제작시 금형 등과 같은 방법으로 형성하며, 그 간격은 일정한 배열로 형성시킨다.The uneven portion 10 is formed by a method such as a mold when manufacturing the lower glass panel 2, the interval is formed in a constant arrangement.
그리고 요철부(10)의 표면상에다는 통상의 스크린 인쇄법에 의해 형광체를 도포시켜 형광면(7)을 형성한다. 또한,(15)는 수은의 여기하에서 발광할때의 빛을 차단 또는 반사시키는 코팅막이다.On the surface of the uneven portion 10, a fluorescent substance is applied by the usual screen printing method to form the fluorescent surface 7. Reference numeral 15 denotes a coating film for blocking or reflecting light when emitting light under excitation of mercury.
상기 코팅막(15)은 하판 유리판넬(2)의 외표면에 스프레이 또는 기타 인쇄방법으로 도포하여 형성하며, 그재질은 알루미늄 등의 반사재질을 사용한다.The coating film 15 is formed by applying a spray or other printing method to the outer surface of the lower glass panel 2, the material is a reflective material such as aluminum.
이와같이 하판 유리판넬(2)의 내, 외 표면에 일정하게 배열된 요철부(10)와 코팅막(15)을 구성한 본 고안의 실시예는 제3도(a)(b)에 도시한 바와같이 수은의 여기하에서 빛이 발광될때 그 발광빛은 방전공간(4)에서 형광면(6)을 통해 상판 유리판넬(1)로 투과되고, 하판유리판넬(2)에 투과되는 빛은 외표면에 도포된 코팅막(15)에 의해 재반사된다.As described above, the embodiment of the present invention including the uneven portion 10 and the coating layer 15 uniformly arranged on the inner and outer surfaces of the lower glass panel 2 is shown in FIG. 3 (a) (b). When light is emitted under excitation of the light, the emitted light is transmitted to the upper glass panel 1 through the fluorescent surface 6 in the discharge space 4, and the light transmitted to the lower glass panel 2 is coated on the outer surface. It is reflected back by (15).
또한 요철부(10)에 의한 발광면적(S)은 제3도 (b)와 같이 S=(b+c)·L이 되므로, 하판 유리판넬(2)의 내표면에 형성된 요철부(10) 만큼 더 넓어진다.Further, since the light emitting area S by the uneven portion 10 becomes S = (b + c) · L as shown in FIG. 3 (b), the uneven portion 10 formed on the inner surface of the lower glass panel 2 is formed. As wider as
따라서, 감쇠되는 빛을 차단하고 재반사시킴에 의해 휘도는 5인치 액정표시 텔레비전의 평판형 냉음극 형광램프를 기준으로 했을때 3000nt에서 4500nt 까지 높아진다.Therefore, by blocking and re-reflecting the attenuated light, the luminance is increased from 3000nt to 4500nt based on the flat cold cathode fluorescent lamp of the 5-inch liquid crystal display television.
이상에서 설명한 바와같이 본 고안의 평판형 냉음극 형광램프에 의하며, 하판 유리 판넬의 내표면에 다수의 요철부를 형성케 함으로서 요철된 부위만큼의 발광면적을 넓힐 수 있을 뿐 아니라, 하판 유리 판넬의 외표면에 반사 코팅막을 형성케 함으로서 손실되는 발광빛이 차단되어 휘도를 증가시킬 수 있는 효과가 있다.As described above, the plate-type cold-cathode fluorescent lamp of the present invention, by forming a plurality of uneven portions on the inner surface of the bottom glass panel, not only can widen the light emitting area by the uneven portion, but also the outside of the bottom glass panel By forming a reflective coating film on the surface is lost the emitted light is effective to increase the brightness.
