Currently more and more luminaires are using the intelligent controllers for smart lighting system or fans to cool down the fixtures so they want to use a DC power source which is normally 12V or 24V with small power like 1~3W. Basically there are two solutions to have the small power, one is using an independent AC/DC adapter and the other is to use an integrated solution which means that the LED power supply contains the auxiliary power.

Figure 2: Integrated Solution
Integrated solution has overwhelming advantages over independent solution as below:
- 10kV surge protection and IP67 are the standard protection of uPowerTek LED drivers, while normal AC/DC adapters are 1kV and IP54 protected. Integrated power supply is strongly protected by the LED driver so much more reliable than adapters especially for industrial usage or outdoor.
- Easier wiring. Apparently integrated solution has less wires and much simpler connection.
- Less cost. Integrated solution just adds around 2-3 USD compared to standard drivers, but a waterproof reliable AC DC adapter costs much higher than that.
