Externally controlled LED wall washer replaces the traditional internally controlled LED wall washer. The external control wall washer is not flexible due to the fixed procedures. It cannot meet most lighting projects. Many LED projects purchase externally controlled LED wall washer lights. The externally controlled wall washer can be made into monochrome, colorful gradient, colorful, chasing flowing water, and can guarantee the synchronization of lighting effects.

Working principle of high power LED wall washer

Due to the large heat dissipation and good heat dissipation, high-power LED wall washer lights greatly reduce the planning difficulty. However, in practice, constant current drivers are not very good, and many of them have been damaged. So how to make high-power LED wall washer work well, the focus is on handling and driving, let us learn together.

Led wall washer manufacturer

1. LED constant current device. Regarding high-power LED products, we will mention constant current drive, that is the so-called LED constant current drive? No matter what the load changes, LED constant current circuit is called LED constant current drive. If high power LED wall washer is used with 1W LED, we usually use 350MA constant current LED driver. The purpose of using LED constant current driver is to improve the life and light attenuation of LED. The choice of constant current source depends on its power and stability. I try to choose a constant current source with high power whenever possible in order to reduce energy loss and temperature.

2.High-power LED wall washer Let us analyze the function of the first use of high-power LED wall washer and the functions of high-power LED wall washer that can be completed. Through the control of the built-in microchip, it is used in small projects In addition, you can use the manipulator to complete dynamic effects such as mutation, jump, color sparkle, random sparkle, and mutation replacement. You can also use DMX control to complete chase and scan effects.

3. Use occasions: single building, history of the former group of building exterior lighting. The interior of the building is completely exposed to light and interior lighting. Green landscape lighting high power LED wall washer billboard lighting. Medical, civilized and other professional equipment lighting. Bars, ballrooms, etc.

However, externally controlled LED wall washes require more attention than traditional internal controls. The following issues related to production and installation need attention, and external control LED wall washer manufacturer BETTER will share with you:

1. The external control LED wall washer must use a dedicated aluminum substrate. Traditional boards cannot be used because wall washer lamps usually require a voltage of 24V. Traditional aluminum substrates cannot be supported by a 24V power supply. 6 strings 6 and special The board;

2. The core wire of the external control wall washer lamp power cable (including male and female bus pairs, back line) needs to ensure more than 0.75 square, so the female and female twisted pair connector can be connected in series 8 (actually, the inside of the real line is Together, the only thing seen from the outside is the strings, and avoid burning lines because the core is too small;

3, select different specifications of the signal line and the power line of the bus and the bus line to connect, in addition to the size of the power line and the signal line between the male and female pair (power line male and female pair large, small signal line), it is best There are color differences, easy to identify the installation, to avoid confusion, only from the size of the difference, to avoid unnecessary waste of work.

  Installation Precautions:

1, it is best to install the first signal cable first. If you connect the power cable first, some manufacturers will install a female cable on the No. 8 light, so that the signal cable will touch the line, so it is possible to burn the power inside the IC;

2, do not exceed 8 connectors, the current will burn the circuit if it is too large;

3, Do not connect the power cable to the signal cable,

4, the external control program is 24V, do not connect 220V;

5, male and female connectors must be tightened with lock nuts, otherwise it will penetrate into the aluminum plate of the lampshade;
