In order to form an effective circuit connection with the external power supply, and to consider the design symmetry of the overall panel, the first substrate 121 may add the frame-shaped surrounding area 124 to the outer end portion 128 of the electrode 126 more than the second substrate 122. Therefore, the ratio of the light-emitting area of the existing light-emitting module 12 (ie, the area of the photoelectric light-emitting unit 125) to the overall maximum area (ie, the area of the first substrate 121) is small, that is, the effective light-emitting area is relatively low, resulting in assembly. The manufactured lighting fixture 1 is bulky and cannot be effectively reduced. At the same time, because the first substrate 121 has more frame-shaped peripheral regions 124 than the second substrate 122, in the process, for example, handling, Because the surrounding area 124 is partially broken and damaged, it causes additional damage.

As described above, it is known that improving the ratio of the light-emitting area in the organic light-emitting diode illumination device and improving the portion of the first substrate 121 that is more likely to be damaged by the second substrate 122 is one of the research directions in the industry.

The invention also has the same shape and equal area of the first substrate and the second substrate, and is not easily damaged during the process.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 4, a first preferred embodiment of the lighting fixture 2 of the present invention comprises a housing 3 and at least one lighting module 4 disposed in the housing 3, and is electrically connected to an external power source, such as a household socket. It illuminates while used for lighting.

Referring to FIG. 5 and FIG. 6 , the light emitting module 4 includes a first substrate 41 , A second substrate 42, a photo-emitting unit 43, a plurality of electrodes 44, and a plurality of conductive blocks 45.

The first substrate 41 and the second substrate 42 are rectangular glass plates having the same shape and shape, and are spaced apart from each other and connected to each other by a packaging material. The second substrate 42, the first substrate 41 and the packaging material define a sealed installation space 411, and a surrounding space 412 that surrounds the installation space 411 and communicates with the outside.

The photo-luminous unit 43 is an organic light-emitting diode, and is installed in the installation space 411 and can emit light when receiving electric energy.

The electrodes 44 are a pair of cathodes and anodes, and cooperate with each other to supply electric energy to the photoelectric light-emitting unit 43. Each of the electrodes 44 has an inner end portion 441 electrically connected to the photoelectric light-emitting unit 43 and a opposite end. The end 441 is located at the outer end 442 of the surrounding space 412.

The conductive blocks 45 are respectively a solid conductive silver paste and have a body portion 451 and a protruding portion 452. The body portion 451 is disposed in the surrounding space 412 and is electrically connected to the outer end portion 442 of one of the electrodes 44. The protruding portion 452 extends from the main body portion 451 and protrudes from the edge of the first substrate 41 and the second substrate 42 to be electrically connected to an external power source (not shown), and further The light emitting unit 43 supplies electric energy to cause it to emit light.

The protrusions 452 form a plurality of contact points that can be electrically connected to the external power source. When the protrusions 452 are electrically connected to the external power source, the current of the external power source flows through the body portions 452 through the body portions. The 451 reflows to the outer end portion 442 of the electrodes 44, and then flows to the inner end portions 441 via the outer end portions 442, and then flows from the inner end portions 441 to the photoelectric light-emitting unit 43. The photo-luminous unit 43 is caused to receive electric light to emit light that has passed through the first substrate 41.

Compared with the conventional lighting fixture, the first preferred embodiment is electrically connected to the external power source by the protrusions 452 protruding from the edges of the first substrate 41 and the second substrate 42. Therefore, the first The substrate 41 does not need the surrounding area of the conventional light-emitting module, and the first substrate 41 and the second substrate 42 can be designed to have the same shape and shape, and still maintain an effective electrical connection with the external power supply and the design symmetry of the overall panel. Therefore, the ratio of the light-emitting area (ie, the area of the photoelectric light-emitting unit 43) to the overall maximum area (ie, the area of the first substrate 41) of the first preferred embodiment is larger than a conventional ratio, that is, the effective light-emitting area is smaller than the conventional one. Large, at the same time improve the conventional lighting fixtures because the two substrates are not the same size, resulting in a large area of the substrate in the process of the lamp is easy to break, and can reduce the waste of the substrate material, the assembled lighting fixtures can also be reduced in size.

Referring to Figures 7 and 8, a second preferred embodiment of the lighting fixture of the present invention is similar to the first preferred embodiment except that the extension 453 of each of the conductive blocks 45 formed by curing of the conductive silver paste is used. Through the second substrate 42, it is electrically connected to an external power source (not shown). In more detail, the conductive blocks 45 are drilled with at least one hole at the edge of the second substrate 42 corresponding to the position where the conductive blocks 45 are disposed, and then injected with conductive silver from the hole. The glue fills and fills the predetermined portion of the surrounding space 412 and contacts the outer end portion 441 of the electrode 44. After the conductive silver paste is cured, the body portion 451 and the extending portion 453 are formed, and the extending portion 453 penetrates the second portion. The substrate 42 is a conductive block 45 that can be electrically connected to an external power source.

The second preferred embodiment utilizes the surface that protrudes the surface of the second substrate 42 The extension portion 453 is electrically connected to the external power source as a contact point, so that the current of the external power source flows through the main body portion 451 through the extension portion 453 and flows to the outer end portion 442 of the electrode 44, and then passes through the extension portion 453. The outer end portion 442 flows to the inner end portions 441, and then flows from the inner end portions 441 to the photo-emissive unit 43 to cause the photoelectric light-emitting unit 43 to receive electric energy and emit through the first substrate 41. Light.

The only difference from the first preferred embodiment is that the contact point that is operatively electrically connected to the external power source is the extension 453, while still reducing the outer end portion 442 around the same as the first preferred embodiment. The area in the space 412 is such that the first substrate 41 does not require the surrounding area of the conventional light-emitting module, so the effect achieved is the same as that of the first preferred embodiment.

In summary, the two preferred embodiments of the lighting fixture 2 of the present invention improve the disadvantages associated with the manner in which the conventional lighting fixture is electrically connected to the external power source by electrically connecting the conductive block 45 to the external power source. A luminaire having a large effective illuminating area is obtained, and at the same time, the first substrate 41 and the second substrate 42 are uniform in size and shape, and are not easily damaged during the manufacturing process.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
