Analysis of structure and voltage control method of Led wall washer

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, in 2013, the wall washers of other light sources were gradually replaced by LED wall washers. LED wall washers are used in single building, historical building group exterior lighting, building exterior lighting, indoor partial lighting, green landscape lighting, billboard lighting, medical, cultural and other special facilities lighting, bars, dance halls and other entertainment Location atmosphere lighting, etc.
The power module of the LED wall washer is installed inside the casing, and the space is limited. Some manufacturers can solder the surface of the pin-type component to the PCB in order to save space. This is unacceptable. These surface-welded pin-type components are likely to fall off due to soldering or the like, posing a hazard. Therefore, it is necessary to adopt a jack welding method for these components. If the surface welding method has to be used, it is necessary to provide additional protection for the component by means of glue fixing.
Led wall washers, looking for the meaning of the word, means that the lights are washed like water, over the wall, used for architectural decorative lighting and outline the use of large buildings. Through the smooth situation, he was also called the linear led floodlight . The shape is mostly rectangular, his production technology and product parameters are generally consistent with led floodlights. Of course, the difference with traditional led projection lamps lies in the square and round appearance, and the rectangular led wall washer can better dissipate heat.
For LED wall washers, there are currently two control methods: internal control and external control. The internal control means that the external controller is not needed, and the designer designs the control system inside the wall lamp. The degree of effect cannot be changed. The external control is the external controller, and the effect can be changed by adjusting the button of the main control. Usually in large projects, customers can change their own effects. We all use external control. There are also many wall washing systems that directly support the DMX512 control system.
Compared with other architectural lighting, LED wall washers have better energy-saving features, and have many features such as high luminous efficiency, rich colors and long service life. At present, wall washers of other light sources are gradually replaced by high-power LED wall washers.
LED wall washers are small and light in terms of volume, and they are mainly high-power LED light sources in power!
