Detailed description of the specific embodiment

[0031] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0032] The present invention discloses a flexible OLED lighting fixture. Referring to Figure 1 and Figure 2 , it includes a lamp body 1. The lamp body 1 includes a mounting frame 2 and a light-emitting element 3. A cavity 4 is provided inside the mounting frame 2. The light-emitting element 3 is installed in the cavity 4 of the mounting frame 2. A heat dissipation structure 5 is provided between the light-emitting element 3 and the mounting frame 2. The light-emitting element 3 is an OLED flexible light-emitting panel 31. The OLED flexible light-emitting panel 31 can be bent. A power interface 10 is provided on the OLED flexible light-emitting panel 31. The power interface 10 is used to connect to an external power supply to supply electrical energy to the flexible OLED light-emitting panel. At the same time, the OLED flexible light-emitting panel 31 is closely attached to the heat dissipation structure 5 for effective heat dissipation through the heat dissipation structure 5.

[0033] The heat dissipation structure 5 includes a heat sink 51 and a heat pipe 52. The heat sink 51 is thermally connected to the light-emitting element 3. The heat pipe 52 connects the heat sink 51 and the mounting frame 2. There is a gap between the heat sinks 51 to form a ventilation duct. Ventilation holes 53 are provided around the heat sink 51, and the ventilation holes 53 are provided on the light-emitting element 3. During use, the OLED flexible light-emitting panel 31 serves as the light-emitting element 3 and generates a certain amount of heat during operation. This heat is first absorbed by the heat sink 51 and then quickly conducted to the mounting frame 2 through the heat pipe 52. On the mounting frame 2, the heat is further dissipated to the outside. At the same time, the design of the ventilation duct and the ventilation holes 53 also effectively promotes the air flow and helps the heat dissipation system work more efficiently. In this way, it can be ensured that the OLED flexible light-emitting panel 31 always remains within a suitable temperature range during operation, thereby greatly improving the service life and performance stability of the lamp.

[0034] Referring Figure 2 and Figure 3 , the mounting frame 2 is designed to be split-type and includes a detachable first frame 21 and a second frame 22. Inside the cavity 4 of the mounting frame 2, the OLED flexible light-emitting panel 31 is properly placed and firmly fixed to the frame through the elastic positioning structure 6, ensuring the stability and use safety of the light-emitting element 3. The elastic positioning structure 6 includes a plurality of fixing plates 61 fixed to the first frame 21. Two of the plurality of fixing plates 61 are combined in pairs, and the two fixing plates 61 are arranged along the height direction of the first frame 21. A plurality of telescopic springs 62 are vertically fixed to the inner wall of the fixing plate 61. These telescopic springs 62 have good elasticity and recovery performance. They can not only stretch and contract, but also absorb and buffer the impact of external forces on the light-emitting element 3 to a certain extent. One end of the telescopic spring 62 away from the inner wall of the fixing plate 61 is vertically fixed to an elastic plate 63, and the elastic plates 63 abut against each other on the light-emitting element 3. The surface of the elastic plate 63 is made of a relatively soft material to prevent damage to the OLED flexible light-emitting panel 31. These components cooperate with each other to effectively fix the light-emitting element 3 to the mounting frame 2.

[0035] Referring Figure 2 and Figure 4 , fixing structures 7 are provided on the first frame 21 and the second frame 22. The fixing structure 7 includes a plurality of fixing blocks 71 provided on the top of the first frame 21, and a plurality of slots 72 are provided on the second frame 22. The fixing blocks 71 and the slots 72 have the same shape and size, and the fixing blocks 71 are clamped in the slots 72. Threaded holes 8 are provided in the slots 72 and the fixing blocks 71, and fixing bolts 9 are threadedly connected to the threaded holes 8. The fixing bolts 9 are used to further fix the fixing blocks 71 and the slots 72. This detachable connection composed of the bolts and the threaded holes 8 facilitates the disassembly of the first frame 21 and the second frame 22, making installation and use more convenient.

[0036] Working principle: A flexible OLED lighting fixture designed by the utility model fixes the OLED flexible light-emitting panel 31 on the first frame 21 through the elastic positioning structure 6, and then fixes the first frame 21 and the second frame 22 to each other through the fixing structure 7. During use, the OLED flexible light-emitting panel 31 is connected to an external power supply through the power interface 10. After obtaining electrical energy, it emits light. As the use time increases, the heat generated by the light-emitting panel is quickly conducted to the installation frame 2 through the heat sink 51 and the heat pipe 52, and with the design of the ventilation duct and the ventilation holes 53, efficient heat dissipation is achieved, ensuring that the lighting fixture maintains good performance and service life while working efficiently.

[0037] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
