LED Wall Washer Lights

Common lighting fixtures used for exterior wall illumination and advertising display include LED wall washer lights, LED advertising screens (including LED shaped screens), and dynamic outdoor advertising projection lights. These fixtures, using different technical principles and display methods, meet the dual needs of building exterior lighting and advertising communication. Their specific characteristics are as follows:

1. LED Wall Washer Lights
LED wall washer lights are the basic equipment for exterior wall illumination. Their core function is to evenly illuminate building facades to create an integrated lighting effect. High-density LED beads are arranged inside the fixture, combined with lens design, allowing precise control of the light angle (typically 15°-120°), ensuring no dark spots on the wall surface. Their advantages include low energy consumption, long lifespan (up to over 50,000 hours), and support for RGBW four-color mixing technology, capable of displaying 16 million color variations. In advertising applications, LED wall washer lights are often used as background lighting, creating a layered contrast with dynamic content-for example, highlighting building contours with warm white light, then overlaying colorful advertisement images on LED screens.

2. LED Advertising Screens (including shaped screens)
LED advertising screens are the core carriers of dynamic advertisements and include regular rectangular screens and shaped screens (such as curved screens, cylindrical screens, etc.). Their display principle is based on LED dot matrix lighting, where driver ICs control the on/off state and color of each pixel, enabling high refresh rate (≥3840Hz) dynamic image playback. Regular screens typically have pixel pitches of P3-P10 millimeters, suitable for medium to long-distance viewing; shaped screens use flexible PCBs or modular assembly to adapt to complex building surfaces. For example, a commercial complex in Shanghai uses a P6 curved screen to wrap a building corner, achieving seamless integration of advertising content with the building form. Additionally, LED screens support audio-visual synchronization and can connect to audio systems to enhance communication effects.

3. Dynamic Outdoor Advertising Projection Lights
Projection lights use high-brightness laser or LED light sources combined with DLP/LCoS imaging technology to project dynamic patterns or text onto walls. Their core advantage is the lack of installation limitations; they can be quickly deployed without damaging building structures. For instance, a brand once used a 30,000-lumen projector to display a giant product poster on a landmark building's wall at night, covering over 500 square meters. Projection lights support real-time content updates and can be linked with lighting control systems through the DMX512 protocol, enabling dynamic interaction between advertisement content and the surrounding environment.

In actual applications, these three types of fixtures are often used in combination: LED wall washer lights provide basic illumination, LED screens display core advertising content, and projection lights add dynamic elements, together creating an immersive visual experience.
