DETAILED DESCRIPTION
[0030] The present invention will be described in further detail below with reference to the accompanying drawings. Like components are denoted by like reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.
[0031] The utility model discloses an OLED flexible wall washer lamp, referring to Figure 1 and Figure 2 , which includes a long strip of light bar 1, and an adhesive 14 is provided on one side of the light bar 1. The light bar 1 is fixed to a wall of different materials by the adhesive 14. In addition to the adhesive 14, a threaded hole can also be opened on the light bar 1 to fix the light bar 1. A plurality of light-emitting units 2 and a highly flexible material 3 are provided in the light bar 1. The highly flexible material 3 includes but is not limited to polyester film, polyimide film or polyetheretherketone film. The highly flexible material 3 is filled into the interior of the light bar 1, providing flexibility and stability in the product structure. The light-emitting units 2 are linearly arranged in sequence in the light bar 1. The light-emitting units 2 are arranged into a multi-layer structure, including an electrode layer 6, an organic light-emitting layer 7 and an encapsulation layer 8. The electrode layer 6 includes an anode and a cathode, which is used to provide the current required for OLED light emission. The organic light-emitting layer 7 includes a variety of organic materials and can emit visible light under the action of an electric field. The encapsulation layer 8 uses a material with both air permeability and water resistance to protect the internal OLED light-emitting layer from being affected by the external environment. The encapsulation layer 8 is provided on the side of the organic light-emitting layer 7 and the electrode layer 6, so that the light-emitting unit 2 can emit light normally.
[0032] Reference Figure 1 and Figure 3 In order to effectively dissipate the heat generated by the OLED during operation, the outside of the light-emitting unit 2 is covered with a colloid 4. The colloid 4 is made of a soft material, such as rubber. There is a gap between the colloids 4, and the gap is filled with a highly flexible material 3. A heat dissipation structure 9 is provided on the outside of the colloid 4. The heat dissipation structure 9 includes a heat sink 91 fixedly connected to the outside of the colloid 4. The heat sink 91 is used to efficiently transfer heat from the light-emitting unit 2 to the external environment, thereby preventing overheating and ensuring the normal operation and life of the OLED.
[0033] A flexible circuit board 5 is bonded to one side of the colloid 4. This flexible circuit board 5 is embedded in the highly flexible material 3 and electrically connected to the OLED light-emitting units 2. This flexible circuit board 5 not only has high flexibility to adapt to the bending of the light strip 1, but also undertakes the task of electrically connecting to each OLED light-emitting unit 2. A power supply device 12 is connected to one side of the flexible circuit board 5, which is used to provide power to the light-emitting units 2. A controller 13 is connected to one end of the light strip 1. This controller 13 is connected to the flexible circuit board 5. The addition of controller 13 makes the use of this OLED flexible wall washer more convenient and intelligent. The controller 13 maintains data communication with the flexible circuit board 5, allowing staff to precisely adjust the on / off state and brightness level of the OLED light-emitting units 2 through controller 13 to meet the lighting needs of different scenarios.
[0034] In order to improve the lighting effect, through holes 10 are designed on the surface of the light strip 1. The positions of these through holes 10 precisely correspond to the positions of the internal light-emitting units 2. A lens 11 is provided on the outside of each through hole 10. The lens 11 is semicircular. The lens 11 can not only effectively transmit the light source of the light-emitting unit 2 to a farther external space, but also enhance the uniformity and directionality of the light. The lens 11 is connected to the light strip 1 in a detachable manner and can be replaced separately when damaged, reducing maintenance costs.
[0035] Working Principle: This utility model designs a flexible OLED wall washer light. When a worker connects the power supply and activates the OLED flexible wall washer light via the controller 13, current flows from the power supply 12 through the flexible circuit board 5 to each OLED light-emitting unit 2. Under the action of this current, the organic light-emitting layer 7 begins to emit visible light. Simultaneously, the heat dissipation structure 9, particularly the heat sink 91, begins to operate, dissipating the generated heat in a timely manner to ensure stable operation of the OLED. Because the wall washer light is filled with highly flexible materials and the flexible circuit board 5 is provided, it is more flexible and suitable for curved and complex areas, achieving soft lighting.
[0036] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
