What is LED Wall Washer?
- Aug 13, 2018 -

Led wall washer, also known as linear LED floodlights, etc., because of its long shape, it is also known as LED line light, its technical parameters are similar to LED floodlights, relative to LED floodlights The circular structure, the heat dissipation device of the strip structure of the LED wall washer is more convenient to handle.

LED wall washers, as the name suggests, let the lights wash the wall like water, mainly used for architectural decoration lighting, as well as to outline the large buildings! Because LED has the characteristics of energy saving, high luminous efficiency, rich color and long life, it is widely used!


Basic definition

Wall washers, as the name suggests, let the lights wash the wall like water, mainly used for architectural decoration lighting, as well as to outline the large buildings, because LED has energy saving, high luminous efficiency, rich colors and long life. And other characteristics, so the wall washers of other light sources are gradually replaced by LED wall washers. The technical parameters of LED wall washers are similar to those of LED floodlights.

Basic parameters

The LED wall washers with more applications are basically 1W high-power LED tubes (each LED tube will have a high-efficiency lens made of PMMA, the main function of which is to distribute the light emitted by the LED tube twice). Single-line arrangement (I classify it as LED flood light in two-line or multi-line arrangement). Most LED wall washers share a single heat sink. The angle of illumination is generally narrow (about 20 degrees) and medium ( Three kinds of 50 degrees) and width (about 120 degrees). The farthest effective projection distance of high-power LED wall washers (narrow angle) is 5-20 meters. The common power is about 9W, 12W, 18W, 24W. 36W and other power forms, and their common external dimensions are generally 300, 500, 600, 900, 1000, 1200, 1500mm, etc., and different lengths and power densities can be selected according to actual engineering applications.



Projection distance: According to the lens 5~20 meters, the smaller the angle, the farther the projection distance is.

Luminous angle: 6-90 degrees floodlight

Mirror surface: glass reflective lens, light transmittance is 98-98%, not easy to atomize, can resist UV radiation

The lamp body is made of pure aluminum and has a variety of optional shapes, such as square and long strips. The optional length can be any: 300, 500, 600, 1000, 1200, 1500mm. The width and height are fixed (1 meter is a regular product)

Protection level: IP65 - IP67 (IP68 highest) structural waterproof wall washer effect up to I67, with high waterproof, long time and other characteristics. Even if it is used for a long time, it will not affect its waterproof performance! !

There are also many types of wall washers, including long strips, circles, squares, lengths and sizes, which can be used for installation and use of different shapes. The control mode is also controlled by the original master-slave connection. It has been developed to support offline or built-in control. The installation mode also supports wireless DMX control. The lamp beacon channel is also upgraded from the original 3 channels to 4 to 20 channels. Each set of lamp beads can be freely configured with illuminating effects to achieve different color shaping effects, creating a completely different visual effect for large buildings!

Power specifications: can be divided into DC and AC, generally built-in power supply external AC220V (Japan,US AC110V) mains, etc., externally, generally low voltage DC24V, DC12V, DC27V and so on. The voltage varies depending on the requirements.

Color specifications: full color, colorful color, red, yellow, green, blue, purple, white and other colors.

Development trend: Wall washers are mainly developed in ultra-thin areas, because ultra-thin wall washers are relatively cheaper to transport and more convenient at high altitudes.

Control methods.

The high-power LED wall washer has two control modes: external control and internal control. The internal control can be equipped with multiple change modes (up to six types) without an external controller, while the external control must be configured with an external control controller to achieve color change. The application on the market is also dominated by external control.

Application and effect

The LED wall washer is controlled by the built-in microchip. In small engineering applications, it can be used without a controller. It can realize dynamic effects such as gradation, jump, color flicker, random flicker, gradual alternation, etc. It can also be controlled by DMX. Achieve chasing, scanning and other effects. The main application fields are: single building, historical building group exterior wall lighting; building exterior light, indoor partial lighting; green landscape lighting, billboard lighting; medical, cultural and other special facilities lighting; bars, dance halls and other entertainment venues Ambient lighting, etc.

Principle editing

LED wall washers are relatively large in size and heat dissipation, so the design is also greatly reduced in difficulty. However, in practical applications, constant current driving will not be done too well, and there are many damages. So how to make the wall washer work better, focus on control and drive, control and drive, and learn about the LED current regulator. High-power products related to LEDs will be lifted to constant current drive. What is LED constant current drive? Regardless of the change in the size of the load, the circuit in which the current of the LED remains unchanged is called LED constant current drive. If the wall washer is used as a 1W LED, usually 350MA LED constant current drive, the purpose of LED constant current drive is to improve the life and light decay of the LED. The choice of constant current source is based on its efficiency and stability, and choose a high-efficiency constant current source as much as possible, which can reduce energy loss and temperature.

The high-power LED wall washer has a range of 10-1 meters, which is very suitable for panoramic floodlighting of internal and external walls such as government lighting projects, commercial places, subways, elevated overpasses, building exterior walls, architectural landmarks, etc. Landscape building, outdoor plaza. Landscape objects and walls, display products. Can adapt to a variety of indoor and outdoor temperature and humidity environment. The colors are red, yellow, white, green, blue, and colorful.

Through the organic combination of colorful light and water, it creates a sense of agility and brings a dreamlike feeling. Light era wall washer LED high power T45 uses 24 high power LEDs as light-emitting components, which is a new generation of green lighting products. The long-distance, large-angle, colorful and colorful effects give people a new visual experience, and people are immersed in the unpredictable color world.
