Description

L. Description of the Invention (1) Field of the Invention The present invention relates to a configuration of a planar lamp having an external electrode of a structure of a flat lamp. Due to its brightness average characteristics, the prior art live flat lamps are widely used in daily life. π can be used as a t-light module in the liquid crystal display used today, and can also be used for lighting or advertising billboards or advertising lights. The flat lamp structure is as shown in Fig. i, and a frame body 10 and a first plate urine 2 are formed to form a closed space 14 in which the space is filled with a rare plate gas (the body is not or: 1 inch, and two electrodes 12 are provided). 12 is connected to a power source 16 when the power source = 'electrodes 12, 12 will cause the rare gas or mercury in the space 14 to freely catch ultraviolet rays, and when the ultraviolet rays are irradiated to the phosphor layer formed on the glass plate (not shown) After the display, visible light is emitted. In this configuration, since the electrodes 2, 12 are provided inside the frame 10, they are easily damaged by sputtering of electrons, and the electrodes are required to be packaged in the frame 10 to increase the manufacturing. Complexity and non-performing rate.

In addition, as shown in Fig. 2, a discharge channel 24 is formed on a glass plate 20, and two electrodes (eiectrode) 22, 22 extend into the light-emitting channel. At 24, '28 is an exhaust pipe that evacuates the illuminating passage 24 and is filled with a rare gas and mercury vapor. This configuration is such that a long tube is bent and then excited by the two electrodes to excite the filled gas. In this configuration, it is necessary to have a technique of bending the light-emitting passage, and in addition, a dark belt is easily generated, and the electrode is located in the light-emitting passage.

1271772 V. INSTRUCTIONS (2) The life is short. In addition, if the temperature difference between the middle and the electrodes at both ends of the light-emitting channel exceeds 5 degrees Celsius, the filled gas may accumulate somewhere, resulting in uneven illumination.

In addition, as in the planar lamp configuration disclosed in U.S. Patent No. 5,850,122, in a space surrounded by the side walls (S i de wa 11 ), a plurality of ridges extend in opposite directions from the opposite side walls. And a bend (cha η ne 1 secti ο η ) between the *, an electrode is disposed at each end of the curve, and a rare gas or a fruit vapor is filled in the curve, and is excited by the two electrodes. The gas is filled to emit light. In such a configuration, it is difficult to fabricate the structure, and the electrode is located in the curve, and the life is short. In addition, this configuration also causes a phenomenon in which the filled gas is accumulated due to a temperature difference. There is also a planar lamp construction as disclosed in U.S. Patent No. 6,034,470, in the interior of a discharge vessel, a plurality of electrode strips extending in opposite directions from opposite sides of the illuminating container into and parallel to each other Arranged on the base plate of the illuminating container. The electrode sheets on the same side are connected to the power supply by the same external lead. Therefore, the voltage of the electrode sheets is positive and negative. Constructed as high. However, the disadvantages of this configuration are the same as those of the above three types. Since the electrodes are disposed in the light-emitting container, α卩' also has the effect of electron sputtering to reduce the life. Further, the electrodes are disposed on the bottom plate, and the generated electric field is the plane of the bottom plate where the electrodes are located. The strongest, the electric field away from the electrode is weak, which may cause the electrons to be excited in some places.

The flat lamp of the present invention can be used to replace the electrode of the present invention with the electrode of the present invention, and the sputtering of the flat lamp of the present invention can be manufactured independently of the shape of the conventional flat lamp. Avoid the temperature difference::: fold: the closed and resulting uneven lighting can cause the filling of the original hair, and also improve the Su Shi σ electrode covered by the electric field of the ten-light Since the three-dimensional Thunder r 图 λ α is arranged in the same plane < electricity % $ & surrounded by a wide, j Ding back high luminous efficiency. This is sufficient and effective in order to make the tenth of the present invention clear and easy to understand. The following is a detailed description of the following, a preferred embodiment, and a first embodiment of the present invention ##3a, 3b As shown, the planar lamp of the present invention covers a structure 30 to form a sealed space 34 filled with a rare gas or mercury vapor.
