Testing of 0.5 Watt LED Bulb
We are testing a 0.5 Watt LED Bulb at 220 Volts UPS AC input. We are using Embuilt SPEA-1 to test the Bulb properties.
Specifications:
230 Volts AC, 50 Hz, 0.5 W
Voltage 3rd Harmonic Value of 0.5 Watt LED Bulb by SPEA-1
When power is on the following results are found:
- Vrms: 223.0 Volts
- Arms: 18.53mA
- Watt: 0.332Watt
- VTHD%: 1.4%
- ATHD%: 19.7%
- V3rd Harmonics Value: 0.577 Volts
Analysis: Here we can see that VTHD is 1.4% Supply has small 1.4% distortion in Voltage.
ATHD % is 19.4 which means LED Driver(Internal in LED Bulb) distorted the AMPS waveform by 19.4%. It also has effect of Voltage THD.
We can also see the 3rd harmonics of Voltage is 0.533Volts.
Voltage 3rd Harmonics % of 0.5 Watt LED Bulb by SPEA-1
Here we can see the 3rd harmonics of voltage in % of first harmonics. 3rd Voltage harmonics is 0.336% of Vrms Harmonics.
Amps (Current) 3rd Harmonics Value of 0.5 Watt LED Bulb by SPEA-1
Here we can see the 3rd harmonics Value of Amps. It is 1.630mA it has another waveform with Amps(Current) level of 1.630mA.
AMPS(Current) 3rd Harmonics % of 0.5 Watt LED Bulb
In the above image 3rd Harmonics of Amps shows in display 6. It is 8.6% of Arms (18.45mA).
Other parameters can also be seen on SPEA-1.
You can also view readings on the SPEA-1 Software.
