Problems solved by technology

Therefore, the presence of conductive foreign matter etc. on the protective film will destroy the protective film, resulting in a very high probability of short circuit between the cathode and anode ITO
Especially on organic EL lighting panels with a large electrode area, a thin protective film will significantly increase the probability of short circuit between the cathode and anode ITO, which will become the cause of low yield

Embodiment 1）

[0132] Hereinafter, an organic EL lighting device according to a first embodiment of the present invention will be described.

[0133] First, the structure of the organic EL lighting device of this embodiment will be briefly described.

[0134] The organic EL lighting device of this embodiment is the same as the existing organic EL lighting device. Figure 39 with Figure 40 The four sides on the shown glass substrate 10 have anode terminal electrodes 11 respectively, and the four corners on the glass substrate 10 respectively have cathode terminal electrodes 12, and a sealed container 14 is provided on the glass substrate 10 to cover the organic EL element 13, This prevents performance degradation of the organic EL element 13 due to oxygen, water, and the like. In addition, in this embodiment, the glass substrate 10 is used as the substrate, but other materials such as plastic, metal, and ceramics can also be used as the substrate.

Embodiment 2）

[0160] Hereinafter, an organic EL lighting device according to a second embodiment of the present invention will be described.

[0161] Figure 7 It is a plan view of the organic EL lighting device of this embodiment. Figure 8 yes Figure 7 Cross-sectional view of the section shown in A-A.

[0162] Such as Figure 7 , 8 As shown, the structure of the organic EL lighting device of this embodiment is basically the same as that of the organic EL lighting device of the first embodiment, as shown in Figure 7 , 8 As shown, the difference is that the size of the wiring board 1 is enlarged. This eliminates the need for an operator to directly touch the anode terminal electrode 11 , the cathode terminal electrode 12 , the end surface of the glass substrate 10 , and the like. In addition, in this embodiment, the outer circumference of the wiring board 1 is larger than the outer circumference of the glass substrate 10 by about 0.5 to 3.0 mm.

[0163] However, in the conventiona...

Embodiment 3）

[0167] Hereinafter, an organic EL lighting device according to a third embodiment of the present invention will be described.

[0168] Figure 9 It is a plan view of the organic EL lighting device of this embodiment. Figure 10 yes Figure 9 Cross-sectional view of the section shown in A-A. In addition, although Figure 9 , 10 The connector is omitted in , but the connector is actually installed.

[0169] Such as Figure 9 , 10 As shown, the structure of the organic EL lighting device of this embodiment is basically the same as the structure of the organic EL lighting device of the first embodiment. An anode power supply terminal portion 4a protrudes from the anode wiring 1a, and a cathode power supply terminal portion 4b protrudes from the cathode wiring 1b. This way, you don't have to use Figure 42 With the anode lead-out wire 22 and cathode lead-out wire 23 shown, the connector 24 can be directly connected to the anode power supply terminal part 4a and the cathode...

Abstract

Disclosed is an organic EL illumination device-which is provided with: an organic EL element (13) on a glass substrate (10); and a plurality of anode terminal electrodes (11) and cathode terminal electrodes (12) for evenly supplying current to the aforementioned organic EL element (13) on the aforementioned glass substrate (10)-wherein the organic EL illumination device is provided with a wiring board (1) to which a circuit having anode wiring (1a) corresponding to the position of each of the aforementioned anode terminal electrodes (11), and a circuit having cathode wiring (1b) corresponding to the position of each of the aforementioned cathode terminal electrodes (12) are formed.

Description

technical field [0001] The present invention relates to an organic EL lighting device. Background technique [0002] In the past, in organic electroluminescent (hereinafter referred to as organic EL) lighting devices, in order to make the large-area organic EL lighting panel emit light uniformly, such as Figure 39 , 40 As shown, the anode terminal electrodes 11 are respectively formed on the four sides of the glass substrate 10 , and the cathode terminal electrodes 12 are respectively formed on the four corners of the glass substrate 10 . In addition, in order to reduce the wiring resistance, solder (hereinafter referred to as base solder) is covered across the entire surface of the anode terminal electrode 11 and the surface of the cathode terminal electrode 12 . [0003] Further, current is uniformly supplied to the organic EL element 13 from four directions by the anode terminal electrode 11 and the cathode terminal electrode 12 . [0004] In addition, a hermetic conta...
