Precautions for the production of high-power LED wall washer:

1. The aluminum substrate of the 36W DMX512 external control wall washer must be dedicated, and do not use a conventional one. This is an easy mistake, because the DMX512 external control wall washer generally chooses 24V power supply, and the conventional aluminum substrate is 12 3 series in parallel, 24V power supply can not afford it, you must use a special board with 6 series and 6 parallel;

2. The core of 36W DMX512 external control wall washer (including male-female pair wiring and back wire) must be greater than or equal to 0.75 square, so that 8 male-female pairs can be connected in series (in fact, the real wires inside are all They are connected together, but the appearance looks like they are strung together), the wire core will burn if the wire core is too small;

3. The male and female connectors of the signal cable and the power cable must be of different specifications. It is better to have different colors (the male and female connectors of the power cable are large, and the signal cable is small) because it is tiring during installation. It is sometimes confused only by the size. I had a customer once because the power cable and the signal cable were installed wrongly. , As a result, we called someone over here again, and the back and forth really made people tired, and the result was because of such a small problem. In addition to the different colors and sizes, I now have different steps inside the male and female butt joints, hehe, insurance.

4. There is not much to say about the wiring inside and the glue filling. The guests will know at a glance whether the craftsmanship is good or not.

DMX512 wall washer installation precautions

1. When installing, it is best to connect the signal wire first (if you connect the power wire first, some manufacturers will install the matching female wire on the lamp every 8 wires, the signal wire may touch the wire, which may burn the power inside the power supply. IC);

2. The male and female pairs of connectors cannot be connected in series, and the conventional ones should not exceed 8. If the current is too large, the wire will burn;

3. Do not connect the power line and the signal line in reverse, and the external control is conventionally used as 24V, and do not connect to 220V;

4. The male and female pairs of joints must be tightened with the lock nut, otherwise water will seep into the aluminum plate of the lamp;

5. There are many kinds of controllers, some users like to use SD cards (the speed selection of this controller is best to choose 1, 2, and 3 gears), and the higher speed gears seem to have a better effect on the wall washer. Not obvious, because selecting too quickly may not see the net effect).
