Most of the shapes of LED wall washers (LED strip lights) are strip-shaped, and they are mainly used for architectural decoration lighting or to outline the outline of large buildings to play the role of wall washers. The technology of LED wall washers is roughly similar to the technical parameters of LED floodlights. At present, LED wall washers generally use respirators to solve the balance pressure difference and waterproof problems inside and outside the lamps. The common specifications of the power of LED wall washing are 18W, 24W, 36W, 48w, etc. Its working voltage is AC220V, AC 110V, n24V, DC12V, and the luminous colors are red, yellow, blue, green, white, warm white, amber, RGB . The long beam angle of LED wall washer is 15°, 30°, 45°, generally 300mm, 500mm, 600mm, 1000mm, 1200mm, 0, 90°, 120°, etc. The professional installation bracket can adjust the light at will. The LED wall washer is sealed with special anti-aging heat-conducting silica gel. It has a precise projection angle and can be adjusted horizontally, and its installation is convenient and quick. The internal control LED wall washer does not require an external controller and can have a variety of built-in changing modes. Externally controlled LED wall washers require an external controller for color change.
At present, the LED wall washer lamp body adopts the method of aluminum alloy extrusion molding and the integrated heat dissipation structure design. Compared with the lamp body of the ordinary structure, the heat dissipation area of the lamp body of the battalion structure increases by more than 80%. Clearing the heat dissipation channel ensures the luminous efficiency and service life of the LED. The external control LED wall washer system is mainly composed of a control device, a synchronization cable, an LED wall washer, and a switching power supply. The program of the internal control colorful high-power LED wall washer is fixed and changes less, so it cannot meet the requirements of most projects. The LED wall washer with DMX512 external control generally chooses DC 24V power supply. The conventional board is 12 parallel, and the DC24V power supply cannot bring it up. For the matching DMX512 driver board or DMXS12 power supply, the section of the power line (male-female pair line, back line) of the DMX512 external control wall washer must be greater than or equal to 6 series and 6 parallel. The special board can be used to directly drive it. 0.75mm2, can string 8 pieces on the male and female butt joints. The specifications of the male-female joints of the signal line and the power line must be different, preferably different in color and size (the male-female joints of the power line should be large, and the signal lines should be small).
When installing the DMX512 external control LED wall washer, the signal line should be connected first, and the signal line should be waterproofed, and then use self-adhesive high-pressure waterproof tape to completely wrap the connection for a circle, and finally seal the connection with a heat shrinkable sleeve to prevent Achieve waterproof effect.
Do not connect too many male-female butt joints. Generally, there are no more than 8 wires for DMX512 external control LED wall washer, otherwise the current will be too large and the wires will be damaged.
The power line and the signal line cannot be reversed. The normal working voltage of the externally controlled LED wall washer is DC24V, and the voltage of AC 220V cannot be mistakenly connected.
We should tighten the lock nuts of the male and female butt joints, otherwise water will seep into the aluminum substrate of the lamp. There are many kinds of controllers. Some customers like to use the controller with SD card. The speed is best to choose 1st gear, 2nd gear, and 3rd gear. Higher speed gears will make the effect of the LED wall washer less obvious.
Before installation, people should check whether the voltage marked on the DMX512 external control LED wall washer is consistent with the working voltage at the installation location, so as not to damage the DMX512 external control LED wall washer.
