The LED wall washing lamp is controlled by a built-in microchip. In the application of small engineering, it can be used without controller. It can achieve dynamic effects, such as gradient, jump, color flicker, random flicker and gradient. The manufacturers of LED wall washing lamps can also be controlled by the DMX. Achieve chase, scan and other effects. At present, the main application areas are: external lighting of single buildings and historical buildings; transparent lighting inside and outside buildings, indoor local lighting; green landscape lighting, billboard lighting; lighting of special facilities, such as medical and cultural facilities; bars, song and dance halls, entertainment atmosphere lighting.
About high-power LED products, we will mention constant current drive, so what is led constant current drive?
No matter how the load is, the circuit that keeps the LED current constant is called LED constant current drive. If 1W LED is used in wall washing lamp, 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 choice of constant current source depends on its efficiency and stability. I choose a constant current source that is as efficient as possible to reduce energy loss and temperature. As for how to design high efficiency constant current source, we will make a detailed analysis in "advanced application of LED expert's deception".
Due to the characteristics of energy-saving, high luminous efficiency, rich color and long life of LED wall washing lamp manufacturers, at present, the wall washing lamps with other light sources are gradually replaced by LED wall washing lamps, such as the wall lighting of company buildings and government. The lighting of buildings, historical buildings, walls, entertainment places and so on; the coverage is also more and more wide, from the original indoor to outdoor, from the original local lighting to the current overall lighting, are the progress and development of all levels; today's LED wall washing lamp has been invested in many lighting projects. In the next few years, led wall washing lamp will become an indispensable part of lighting projects.
