Halogen Bulb 230V GU10 LED Bulb Replaced

In most cases flicker is usually related to how the House electrical installation is made. Two possible cases:

Halogen Bulb 230V GU10 LED Bulb Replaced

  1. There are a small neon light in my switches:

These lights of our switches are a little trap for the installations of LED. Internally we can see that the light of neon is is connected in parallel with the contact of the switch and in series with the new luminaire LED. This makes that although the switch is disconnected, a current flow through the light of neon to the luminaire LED. A minimum current but enough (LEDs consume very little) to load the internal capacitors of the luminaire and make that this is so dimly lit or perform constant flashes.

SOLUTION.
The solution simplest would replace neon switch with a normal one or cancel the current switch neon. If you want to keep the neon of our switch, that would have to do is put a resistor in parallel with our installation of LED luminaires. With this resistance will be the small current flowing through the neon already not to flow through the lamp and that it is dimly light with installation power waste. Scheme of the installation for garden wall lights with the help of HealthInclude:

  • My lamp is blinking and I have no neon light in my switch

In this case, it is a problem in the configuration of the electrical installation. In electrical installations we have two poles: the “phase”, which is bringing the charge and “neutral”. Normally in the electrical installation “phase” is that circulates through all electrical devices (switches, switches, etc), while the cable going to the lights is “neutral”.

With this type of facilities we let open a switch so that the luminaire is switched off, but what is done internally is to leave the air a terminal of the bulb, and the other is attached permanently to the neutral.

 

If the cable attached to the luminaire is the neutral and the switch is found open, between them two terminals of the luminaire not is will produce circulation of running any. This is because the air is practically at the same electrical potential as the Earth, or the neutral wire, so our lamps will never turn on.

When this does not happen, the main problem is that the LED lights are directly and continuously the voltage of one of its poles. This will cause a wrong operation and possible flashes and can occur for two reasons:

  • The installation is poorly made and the phase is feeding permanently to the fixture rather than the neutral.
  • In the installation there is one living pole and another neutral, and that instead there are two lines of phase, so again a stage directly feeds fixture. This usually occurs in facilities that supply network is old.
How to tell if the switch cuts the neutral instead of the phase or if I have 2 phases?

With the light off removes the bulb GU10 your cap and with the help of an IGBT test if turns on some of the holes in the CAP.

  • If the IGBT is turned on to the make contact in one only of them holes, is that the switch of our installation not is well connected and short the neutral instead of the phase.
  • If the IGBT turns in both cases, is that our installation has two active phases rather than phase and neutral.
Facilities with 2 active phases or the switch by cutting the neutral instead of the stage. A phase always reach our luminaire.

In this case, the real problem is that the luminaire is continuously receiving directly part of the tension.

As a result and by the effect of induction through the air, a minimum amount of current can circulate between the wires and be able to reach the LEDs lighting them even being turned off. This effect can also occur when the level of isolation of the luminaire is too low or there is some derivation of the power line as the contact with a lamp holder.

Small induced current is his way of “escape” through the LED luminaire that turns due to the little power you need to run.

SOLUTION

Domestic spaces or small installations:

  1. Insulate bulb with tape around Central magnificent of the CAP to avoid contact with the fixture and get you residual energy
  2. Use a capacitor in parallel to the luminaire. Arrive
  3. Use a relay. This solution is especially valid for installations professional or large chucks of luminaires. Installing a relay on the input of the system of lamps, we isolate the installation. In this way we were able to open the two phases that reach our LED lamp and avoid that small circulate currents able to turn on lights. Installation in two-phase systems

Final recommendation for the settlement of the flashing of led bulbs

From Ledbox we recommend the use of a device anti-flicker undoing the excess energy and thus avoid 99% of the flicker problems that generate small loads of tension in our facilities LED. In case of persistence of the problem the solution possibly be required of the Council of a professional of installation electric.
