DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) The technical content of the present invention will become apparent by the detailed description of the following embodiments and the illustration of related drawings as follows.

(13) As shown in FIG. 2, a first embodiment of an OLED lamp module in accordance with the present invention, the planar OLED lamp module includes at least one planar OLED lamp 200 and a slot module 100. The planar OLED lamp 200 includes an OLED substrate 80 and an OLED cover plate 90. The OLED substrate 80 has a light-emitting zone 70 and an OLED electrode surface 80a, and the OLED electrode surface 80a lies between the OLED substrate 80 and the OLED cover plate 90. The OLED substrate surface 80a is provided with at least one exposed positive electrode 60 and at least one exposed negative electrode 50. One side of the frame of the slot module 100 is further provided with at least one slot opening 40, and the slot opening 100 includes at least two elastic metal units 20, 21 disposed therein and capable of connecting to an external power source. The largest side 10 of the slot module 100 has at least one transparent zone 30. The planar OLED lamp 200 can be inserted into the slot opening 40 to electrically connect the exposed positive electrode 60 and the exposed negative electrode 50 of the planar OLED lamp 200 to the elastic metal unit 21 and the elastic metal unit 20 inside the slot opening 40 respectively. Besides, the light-emitting zone 70 of the OLED substrate 80 is corresponding to the transparent zone 30, whereby the light emitted by the planar OLED lamp 200 can be transmitted out of the transparent zone 30.

(14) In the embodiment, the slot module 100 includes at least two elastic metal units 20, 21 therein, and the voltage supplied by the external power source connecting to the elastic metal units 20, 21 does not exceed 12 volts.

(15) In the embodiment, the slot opening 40 further includes at least one elastic element 22, and the elastic element 22 provides a reverse force in the insertion direction of the planar OLED lamp 200 inserted into the slot opening 40 in order to conveniently remove and install the planar OLED lamp 200.

(16) In the embodiment, the elastic unit 22 and the elastic metal unit 20 are integrally formed: in other words, they can be combined to form an elastic composite element 24, as shown in FIG. 3 (FIG. 3 omits the slot module 100 in order to more clearly show the elastic composite elements 24, 25). The elastic composite element 24 has two parts, an elastic metal unit 24a and an elastic element 24b, which allows the elastic composite element 24 to electrically connect to the negative electrode 50; meanwhile, the elastic element 24b can provide a reverse force in the direction of the in the insertion direction of the planar OLED lamp 200 inserted into the slot opening 40. The function of the elastic composite element 25 is similar to that of the elastic composite element 24 in order to facilitate the electrical connection of the planar OLED lamp 200 and users can conveniently remove and install the planar OLED lamp 200.

(17) Besides, as shown in FIG. 4, as the positive electrodes of an OLED lamp usually have higher impedance, the IR drop thereof tends to increase; for the reason, the brightness of the lamp may not be uniform. However, if the positive electrodes 60a, 60b are respectively disposed at two sides of the negative electrode 50 of the planar OLED lamp 201 and the elastic metal units 21a, 21b are also respectively disposed at two sides of the elastic metal unit 20, the negative electrode 50 and the positive electrodes 60a, 60b can simultaneously supply the current for the planar OLED lamp 201; in this way, the brightness of the planar OLED lamp 201 can be more uniform. FIG. 5 shows a different electrode arrangement design for the planar OLED lamp; in the embodiment, the positive electrode 60 and the negative electrode 50 of the planar OLED lamp 202 can be disposed at different sides; similarly, the elastic metal units 20, 21 of the slot module 102 can also be disposed at different sides.

(18) Further, as shown in FIG. 6, according to the first embodiment of the present invention, the planar OLED lamp module 200 can be inserted into the slot module 100, and the light-emitting zone 70 is corresponding to the transparent zone 30, so the light emitted by the planar OLED lamp 200 can be transmitted out of the transparent zone 30. In this way, the planar OLED lamp module 300 can be of simple structure, light and thin; besides, the planar OLED lamp 200 of the planar OLED lamp module 300 can be easily replaced.

(19) Moreover, as shown in FIG. 7, for the purpose of protecting the planar OLED lamp 200 of the planar OLED lamp module 300 to avoid that the planar OLED lamp 200 is damaged due to external impact, the transparent side of the slot module 40 is provided with a protection plate 95 with light transmittance. Meanwhile, the outer surface of the slot opening 40 is provided with a sealing cap 96; the sealing cap 96 can be used to seal the slot opening 40 in order to beautify the appearance and better the integrity of the planar OLED lamp module 300; in addition, the sealing cap 96 can also prevent dust from entering the internal space of the planar OLED lamp module 300. A light and thin planar OLED lamp module 301 of simple structure and with a planar OLED lamp easily to replace is provided after the protection plate 95 and the sealing cap 96 are installed thereon, as shown in FIG. 8.

(20) Furthermore, as shown in FIG. 9 and FIG. 10, the slot module 400, 500 of the planar OLED lamp module can be provided with two or more of the slot openings for two or more planar OLED lamps 200 to be inserted therein, which can satisfy the requirements of larger planar OLED lamp modules and can be applied to various lighting products, such as desk lamp, table lamp, decoration lighting products and common lighting products, etc. Additionally, in response to different appearance designs, the largest side 10 of the slot module 400, 500 is substantially square, rectangular, elliptic or circular in shape so as to match different environment landscape designs.

(21) Many changes and modifications in the above described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
