Problems solved by technology

At the same time, as an electronic device, OLED devices require a power supply for their self-luminescence; however, OLED devices are currently in a fixed power supply mode. Once OLED devices are used to form light sources, their shape and performance are fixed, and it is difficult to achieve customization.

Embodiment 1

[0059] This embodiment provides a cuttable light source, which can be cut into any shape according to requirements, which increases the flexibility of light source customization.

[0060] like Figure 1A and Figure 1B As shown, the light source includes a light source unit 1 having a plurality of light emitting units 10 and a power supply unit 2 arranged on the non-light emitting side of the light source unit 1; and refer to Figure 2A A plurality of light-emitting units 10 are connected in parallel and have a common connection electrode 114, and the common connection electrode 114 is electrically connected to one electrode end of the power supply unit 2, that is, the power supply unit 2 directly supplies power to the light-emitting units 10 in the light source unit 1. Wherein, the light-emitting unit 10 includes a first electrode 11, a second electrode 12 disposed opposite to each other, a light-emitting layer 14 and an insulating layer 13 arranged between the first electrode ...

Embodiment 2

[0074] This embodiment provides a light source. Compared with Embodiment 1, the light source unit 1 in the light source has a better light output effect, or the power conversion component 21 has a better light guide effect, so that the power conversion component 21 has Higher solar utilization.

[0075] like image 3 As shown, the light-emitting side of the light source unit 1 in this embodiment is provided with a plurality of microstructures, and / or, the side of the power supply unit 2 away from the light-emitting side of the light source unit 1 (that is, the power supply unit that is not in direct contact with the light source unit 1 2, under the condition that the light source unit 1 and the power supply unit 2 are assembled together by bonding in Embodiment 1, that is, the non-bonding surface of the power supply unit 2 and the light source unit 1) is provided with multiple microstructures. That is, in this embodiment, a plurality of microstructures 3 (such as image 3 sh...

Embodiment 3

[0080] This embodiment provides a method for preparing a light source, which is used to form the light source in Embodiment 1.

[0081] The preparation method of the light source comprises steps:

[0082] Step S1): forming a light source unit 1, which has a plurality of light emitting units.

[0083] Specifically, forming the light source unit 1 includes:

[0084] Step S11): forming a pattern including the first electrode 11 on the substrate. like Figure 5A As shown, the first electrode 11 includes a first electrode body, a first electrode connecting portion and a first electrode connecting body formed by extending from the first electrode body, and the first electrode connecting bodies of a plurality of light emitting units are electrically connected to each other to form a common connection. electrode.

[0085]Preferably, a plurality of light-emitting units are arranged in an array, and the common connection electrode includes a first common connection electrode formed ...

Abstract

The invention belongs to the technical field of lighting, and particular relates to a light source and a preparation method thereof and a lighting device capable of performing cutting and a preparation method thereof. The light source comprises a light source unit with multiple lighting units and a power supply unit arranged on the non-lighting side of the light source unit; the lighting units are connected in parallel and have a common public connecting electrode, and the public connecting electrode is electrically connected with one electrode tip of the power supply unit. The light source can be cut into arbitrary shapes as needed, and the flexibility of light source customization is improved.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a light source and a preparation method thereof, a cuttable lighting device and a preparation method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, referred to as Organic Light-Emitting Diode) has the advantages of self-illumination, good visibility, high brightness, and thin thickness. In particular, it can be used to form different shapes with flexible substrates and has been widely used. As a planar light source, OLED has advantages that traditional LED lighting cannot match in terms of structure, light source quality, and product features. If LED is the future direction of development, then OLED is the future of the future. [0003] As we enter the 21st century, mankind will face major challenges in achieving sustainable economic and social development. Economic development under the dual constraints of limited resources and strict en...
