In recent years, LED wall washer lights have been widely used in various places, such as the lighting of corporate buildings, the lighting of government buildings, the lighting of historic buildings, and entertainment venues. The wider. From the original indoor to outdoor, from the original local lighting to the current overall lighting, all levels are improved and developed. With the increasing progress of the times, LED wall washer lights will develop into an indispensable part of the lighting project.
 
First, the basic parameters of high-power LED wall washer
1.Voltage
The voltage of LED wall washer can be subdivided into: 220V, 110V, 36V, 24V, 12V, several kinds, so we pay attention to the corresponding voltage when selecting the power supply.
 
2.Protection level
This is an important parameter of wall washer, and it is also an important index that affects the quality of the current fence pipe. We have to carry out strict requirements. We use it outdoors and require the waterproof level to be above IP65. It also requires relevant pressure resistance, chipping resistance, high and low temperature resistance, flame resistance, and impact aging rating IP65. 6 means completely prevent dust from entering; 5 means: rinse with water without any harm.
 
3.Working temperature
Because the wall washer is usually used more outdoors, this parameter is more important, and the temperature requirements are relatively high. Generally, the outdoor temperature we require is -40 ℃ + 60, which can work. However, the wall washer is made of aluminum casing with better heat dissipation, so this general wall washer can meet the requirements.
 
4.Lighting angle
The light emitting angle is generally narrow (about 20 degrees), medium (about 50 degrees), and wide (about 120 degrees). At present, the maximum effective projection distance of high-power LED wall washer (narrow angle) is 20- 50 meters
 
5, LED lamp beads
The number of LEDs for general wall washer is 9 / 300mm, 18 / 600mm, 27 / 900mm, 36 / 1000mm, 36 / 1200mm.
 
6, color specifications
2nd, 6th, 4th, 8th stage full color, colorful, red, yellow, green, blue, purple, white and other colors
 
7.Mirror surface
Glass reflective lens, 98-98% light transmittance, not easy to fog, resistant to UV radiation
 
8.Control method
There are currently two control methods for LED wall washer: internal control and external control. Internal control means that there is no need for an external controller. The designer designed the control system inside the wall lamp, and the degree effect cannot be changed. The external control is an external controller, and its effect can be changed by adjusting the keys of the main control. Usually on large projects, customers require that they can change the effect by themselves. We use external control. There are also many control systems that directly support DMX512 for wall washes.
 
9.Light source
Generally, 1W and 3W LEDs are used as the light source, but due to the immature technology, 1W is currently more commonly used in the market, because 3W has a large amount of heat, and it is not easy to remove heat to do light decay faster. The above parameters must be considered when we choose LED high-power wall washer lights. In order to reduce the light loss and illuminate the light for the second time, the LED lights are distributed. High efficiency lens made of PMMA.

Working principle of LED wall washer
The LED wall washer has a large volume and good heat dissipation, so it also greatly reduces the difficulty in design. However, in practical applications, constant current drive is not very good, and there are many damages. So how to make the wall washer light run better, the focus is on the control and drive aspects, the control and drive aspects. Next, Yuyang Sentai Lighting will take everyone to learn.
 
1.LED constant current
With regard to high-power LED products, we will all mention constant current drive. What is LED constant current drive? No matter the load changes, the circuit that the LED current remains unchanged is called LED constant current drive. If 1W LED is used in the wall washer, we usually use 350MA LED constant current driver. The purpose of LED constant current driver is to improve the life and light attenuation of LED. The selection of a constant current source is based on its efficiency and stability. I choose a constant current source with high efficiency as much as possible, so that energy loss and temperature can be reduced.

2.Application of led wall washer
Let Yuyang Sentai Lighting analyze the main application scenarios and achievable effects of wall washer. LED wall washer is controlled by built-in microchip. Dynamic effects such as jumping, color flickering, random flickering, and gradual alternation can also be controlled by DMX to achieve chasing and scanning effects.

3. Application place
Application places: Exterior lighting of individual buildings and historic buildings. Inside and outside lighting of the building, indoor partial lighting. Green landscape lighting, LED wall washer lighting billboard lighting. Medical, cultural and other special facilities lighting. Atmosphere lighting in entertainment venues such as bars and dance halls
