Led Wash Wall lamp, as the name suggests, is to make light wash the wall like water to outline the outline of a large building! It is also called linear LED flood light, etc. Because of its long shape, some people also call it LED linear light. Its technical parameters are roughly similar to LED flood light. Compared with the circular structure of LED flood light, the strip The heat-dissipating device with the shape structure is better to handle.
Basic parameters of wall washer
Most LED wall washers use 1w high-power LED tubes (each LED tube uses a high-efficiency lens, and its main function is to distribute the light from the LED tube), single-line arrangement (2-line or multi-line arrangement), large Most LED wall washers generally have a light-emitting angle from 10 degrees to 120 degrees. The longest effective projection distance of high-power LED wall washers (narrow angle) is 5-20 meters, and their common power is about 9W, 12W, 18W, 24W , 36W and other power forms, but their common shapes and sizes are 300, 500, 600, 900, 1000, 1200, 1500 mm, etc. Different lengths and power densities can be selected according to actual engineering applications.
Types of wall washer
There are also many shapes of wall washer, including long strip, round, square, length and size can be selected by yourself, suitable for the installation and use of buildings of different shapes.
The installation mode supports wireless DMX control, the lighting effect channel is upgraded from the original conventional 3 channels to 4 to 20 channels, so that each group of lamp beads can be freely configured to achieve different color shaping effects to create completely different large-scale building visual effects !
How does the LED wall washer work?
The LED wall washer has a large volume and good heat dissipation, which greatly reduces the design difficulty. However, in practical applications, constant current drive is not very good, and there are many damages, so how to make the wall washer work better, focus on control and drive, how to control and drive, let us learn about LED constant current. Regarding LED high-power products, constant current drivers will be mentioned, so what is a constant current LED driver? Regardless of the load. The change of LED current is kept constant in a circuit called LED constant current driver. If 1W LED is used inside the wall washer, 350MA LED constant current drive is usually used, and the LED constant current drive is used to improve the life and light attenuation of the LED. The choice of the constant current source should be based on its efficiency and stability, and as much as possible to choose an efficient constant current source, which can reduce the loss of energy and temperature.
Application occasions and effects of wall washer
The LED wall washer can be controlled by a built-in LED chip and can be used for small engineering applications without a controller. It can realize dynamic effects, such as gradual change, jumping, color flashing, random flashing, alternating gradation, etc. Can adapt to indoor and outdoor temperature and humidity environment. The color has red, yellow, white, green and blue, color and other effects. Through the organic combination of colorful light and water, it produces a vivid feeling and brings a dreamlike feeling.
It can also be controlled by DMX to achieve chase, scan and other effects. The main application places are: single buildings, historical buildings, exterior wall lighting; internal and external lighting, indoor local lighting; green landscape lighting, advertising sign lighting; lighting for special facilities such as medical treatment and culture; entertainment in bars, banquet halls and other places Atmosphere lighting.
