Performance
Control mode
1. DMX512
Advantage:
At present, most of the DMX512 control methods are available on the market, which is characterized by strong compatibility of the control method, and a single lamp does not affect the work of other lamps.
Disadvantage:
The disadvantage is that the single-channel drive can only reach 168 points, the transmission rate is low, and the one-way transmission (DMX512-A standard can be two-way transmission) is easier to lose addresses, and cumbersome address coding settings must be made in advance.
2. RSL
Advantage:
RSL control mode is easier to operate (no need to encode addresses one by one), single port control can reach 1024 points, dual control mode can realize non-stop maintenance.
Disadvantage:
The disadvantage is that a bad single lamp will cause the back-end protection to stop working.
3.WTSD5680
Based on the above characteristics, the new WTSD5680 control method has more advantages: it is also DMX512-A standard control method, no address coding is required, and the failure of a single lamp does not affect the work of other lamp bodies. It combines the advantages of the above two, but its controller The cost is slightly higher.
Quality
In terms of quality, in addition to easy installation, the selection principle is also a general principle for outdoor lighting: one is to prevent dead lights, and the other is to prevent short circuits caused by water ingress.
The factors of dead light of LED pixel dot depend on factors such as chip quality, welding quality, heat dissipation effect and constant current. Not to mention short circuit of water inlet. In general, the first choice should be high-quality brand lamp beads, high thermal conductivity aluminum substrate, and constant current. Chips, solid potting products.
