Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting fixtures, and in particular to a flexible wall washer light. Background Technology
[0002] Flexible wall washer lights are flexible, bendable products that use optical lenses to adjust the beam angle, allowing the light to flow across the wall like water. Through the optical lens, they achieve secondary light distribution, adjusting the bidirectional beam angle of the LED light source to redefine the projection distance and beam uniformity. Their function focuses on showcasing a three-dimensional outline from lines to surfaces; in terms of light output, they belong to the category of "area light." Figure 1 The diagram shows a schematic representation of an existing flexible wall washer light. It is formed by covering a light-shielding insulating layer 4' onto a circuit board containing a light source, and utilizing the forward light emission of the light source and optical lens 3' mounted on the insulating layer.
[0003] Combined Figure 2 and Figure 3 The diagram shows a schematic of the internal circuit structure of an existing flexible wall washer light.
[0004] Specifically, in this example, the circuit employs a circuit structure based on a long, flexible FPCB light board. A light source 1' and other components are mounted on the FPCB light board. The FPCB light board is flexible and can be bent in a specific direction. Based on this circuit structure, an optical lens 3' is mounted and fixed at the position of the light source 1. The optical lens 3' enables secondary light distribution illumination of the product.
[0005] Combined Figure 4 and Figure 5 The diagram shows another internal circuit structure in an existing flexible wall washer light.
[0006] Specifically, in this example, the circuit employs a circuit structure formed by connecting multiple rigid printed circuit boards (PCBs) in series. Each rigid PCB 1' houses a light source and other components, and the multiple rigid PCBs 1' are connected by metal wires 2' to form the circuit structure. Utilizing the bendable nature of the metal wires 2', this circuit structure can be used in a flexible configuration. The metal wires 2' can be straight or other structures with bending and deformation capabilities, such as telescopic metal wires, wavy wires, or spiral wires. Similarly, an optical lens 3' is mounted on it and fixed at the position of the light source.
[0007] However, in existing flexible wall washer lights, the combination of the light source and the optical lens directly creates a secondary light distribution effect, with the light passing through the optical lens having a focusing effect. When viewed directly with the naked eye, this may produce an uncomfortable glare effect. At the same time, due to the large contrast between the surrounding environment and the light source, there is an excessively bright light source in darker environments, increasing the possibility of visual discomfort.
