What is an LED wall washer light for outdoor use?
One kind of outdoor landscape lighting is LED wall washer lights. These lights, as their name suggests, provide a water-like washing effect on the wall and are often used to highlight and illuminate exterior walls or architectural elements.It is renowned for producing a wide, uniform beam of light. Usually used for accent or decorative lighting. Because of their long, strip-like design, some people call them outdoor LED strip lights.
LED floodlights and LED wall washers have comparable technological features. However, the linear design of LED wall washers makes them unique and improves their ability to dissipate heat.
Fundamental Parameter
The most common LED wall washers use a 1W high output LED guardrail tube (each LED tube will have a high-efficiency lens made of PMMA, and its main function is to redistribute the light emitted by the LED guardrail tube). They also show single-line arrangement (two-line or multi-line arrangement, classify it as LED floodlight). The majority of the LED guardrail tubes share a radiator, and their light-emitting angles are generally narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). The farthest effective projection distance of high-power LED wall washers (narrow-angle) is 5–20 meters, and their common power is approximately 9W, 12W, 18W, 24W, 36W, and other power forms. Their common dimensions are generally 300, 500, 600, 900, 1000, 1200, 1500mm, etc., and different lengths and power densities can be chosen based on actual engineering applications.
Specification Parameter
Depending on the lens, the projection distance ranges from 5 to 20 meters; the narrower the angle, the greater the distance.
Lighting angle: floodlight at 6 to 90 degrees
Mirror surface: a glass reflecting lens with a light transmittance of 98–98% that is resistant to UV rays and difficult to fog.
Pure metal makes up the lamp body, and it comes in a variety of optional designs, including square and long linear wall washer lights. The length of the optional light may be any of the following: 300, 500, 600, 1000, 1200, or 1500 mm. Height and width are set, with one meter being a standard product.
The impact of a structural waterproof wall washer may reach IP67, with strong waterproof and long-term features. The IP protection level is IP65-IP67 (IP68 being the highest). Its ability to remain waterproof won't be impacted by prolonged usage.
Because LED wall washers are available in a variety of designs, including long, round, and square, they may be installed on a variety of building constructions. The control techniques have changed from master-slave connections to offline or integrated control, with wireless DMX control being a possibility. Light effects channels have increased from three to four to twenty, allowing for adjustable luminous effects for a variety of color shaping and producing distinctive visual effects on massive structures.
There are two types of power supplies: DC and AC. Typically, the external power supply is low-voltage DC24V, DC12V, DC36V, etc., and the built-in power supply is externally linked to AC220V (Japan AC110V) mains, etc. Additionally, the voltage varies depending on the needs.
Red, yellow, green, blue, purple, white, and other hues are examples of full-color and vibrant colors.
Development trend: Ultra-thin outdoor wall washer lights are becoming more popular because they are more practical for high-altitude operations and have comparatively reduced shipping costs.
Way of Control
The integrated microprocessor controls the outdoor wall wash lights. It may function without a separate controller in smaller-scale applications.It is possible to produce dynamic effects such as color pulsations, random fluctuations, abrupt changes, and progressive transitions. As an alternative, DMX may be used to control it and produce effects like scanning and chasing.
Both internal and external control options are available for high-power LED wall washers. Internal control may have up to six built-in color-changing modes and does away with the requirement for an external controller. External control, on the other hand, requires an external controller in order to enable color changes. The majority of market applications use external control.
Application
The 10- to 1-meter irradiation range of the high-power LED wall washer makes it ideal for panoramic floodlighting of both interior and external walls, including those found in government lighting projects, businesses, subways, elevated overpasses, building exterior walls, and architectural monuments. Build landscapes and outdoor plazas. coloring of exhibitions, walls, and landscape elements. able to adjust to different humidity and temperature conditions both inside and outdoors. Red, yellow, white, green, blue, and other effects are among the hues.
