As the name suggests, a wall washer (LED wall washer) is a lighting fixture that projects light evenly across surfaces, such as walls, mimicking the effect of water flowing over them. This type of lighting is often used for decorative purposes and enhancing the visual appeal of architectural projects including commercial buildings, hotels, bridges, and docks, as well as highlighting the contours of large structures.

Features and Functions of Wall Washers

Manufactured primarily by Sobo Optoelectronics, wall washers utilize secondary light distribution to adjust the bidirectional light angle of LED sources. This adjustment redefines the projection distance and light uniformity, focusing the function on transitioning from linear to surface illumination, thereby providing a three-dimensional display of the building's outline.

Light Source and Configuration

Currently, wall washers typically use 1W high-power LED lamp beads as their light source. Each LED is paired with a high-efficiency PMMA lens, which redistributes the light emitted by the LEDs. The lamp beads are usually arranged in a single line, and sometimes in multiple lines, referred to as linear LED floodlights. These LEDs typically share an aluminum profile radiator. Standard luminous angles available are 15, 30, 45, 60, and 90 degrees, though custom angles can be manufactured as needed.

Projection Distance and Specifications

The effective projection distance of LED wall washers usually ranges from 1 to 10 meters, with some high-power narrow-angle designs extending up to 20 meters. They come in various power ratings such as 9W, 12W, 18W, 24W, and 36W, and sizes like 300mm, 500mm, and 1000mm. Custom specifications for length and power can also be accommodated based on project requirements.

Neon Flex LED Wall Washer

Neon Flex LED wall washer units also boast similar projection distances between 1 and 10 meters. These are ideal for wide-area illumination of both interior and exterior walls in places like government buildings, commercial spaces, subways, viaducts, exterior walls of buildings, landmarks, outdoor areas, and landscapes. They are designed to operate efficiently in various indoor and outdoor temperature and humidity conditions.

Visual Effects

Sobo's LED wall washers create a visually engaging experience through the clever combination of colorful light and strategic projection angles. Dynamic lighting effects such as gradients, jumps, color flickering, random flashing, and gradient alternation can be achieved through the control of built-in microchips. Additionally, using a DMX512 control system allows for more complex effects like chasing and scanning.

Common Applications

Wall washers are versatile and can be used in numerous settings including:

• Exterior and historically significant building lighting
• Interior and exterior illumination within buildings
• Local indoor lighting
• Green landscape lighting
• Billboard lighting
• Lighting for medical, cultural, and other specialized facilities
• Creating ambiance in bars, dance halls, and entertainment venues
