0-10V LED high bay light power is what will faint light?
A few days ago, a customer response turn off some 0-10V LED high bay light or dim state, dose product quality has a problem?
In fact, it had nothing to do with 0-10V LED high bay light, this is just a careless electrician made a fundamental mistake!
Why it will light when the power is cut off? Because when electrician installed switch, the power switch is connect zero, not fire. Electrician know power switch must use fire wire, otherwise you will have to get an electric shock risk. when the power fire wire is also continuing to LED drive power supply after Power failure, thus causes 0-10V LED high bay light will also have a faint glow of light.
For a qualified electrician, it is a common sense should not make mistakes.But you know, install electric switch, these things is very simple, are usually considered themselves to take can be done, so the power cuts back light will bright "weird" event is often happened!
Another problem is that: the dual switch control 0-10V LED high bay light, why can appear 6-7 seconds when the power is flashing?
Cause analysis: double switch under the condition of the close socket voltage is measured with a multimeter AC file, found that there are 24 v - 68 v alternating current (AC) in the change, by 24 v - 68 v alternating current change is between 1-7 seconds in a changing, when alternating current (AC) minimization algorithm more than 50V ,LED high bay light will flash once . 68V will quickly jump to 0V, and then to 24 v, 40V will slowly rise. From the LED load, and then measure the dual switch back and forth line found 120 v alternating current (AC), the analysis is double switch circuit, wire is long and has a high potential of parallel line line after the power is still has high potential.Incandescent lamp load without this phenomenon. 0-10V LED high bay light needs such as electric current is small, so the induction accumulates through LED conduction voltage, it put the electricity, LED high bay light is flashing.
