First aid with flashing LED lights

First aid with flashing LED lights

 First aid with flashing LED lights
Blinking, flickering, harder / softer burning, a short flash.

Here you will find the 7 possible causes and solutions!

Causes of flashing LED lamps

   1. The LED lamp is not dimmable

   2. The LED lamp is connected to incandescent or halogen dimmer

   3. The LED lamp is connected to the wrong type of LED dimmer (phase chamfer/chamfer)

   4. LED dimmer settings

   5. An LED lamp (low voltage) is connected to the wrong transformer

   6. Fluctuations in the network

   7. Defective driver

1. The LED lamp is not dimmable

When you set non-dimmable LED lamps to a dim position with a dimmer, the lamps do not receive enough power to cause them to flash. This can give a strobe effect.

Solution: If you want to dim LED, you must connect dimmable LED lamps to an LED dimmer. Do you not necessarily have to dim? Then you can connect an LED light to a normal on / off switch.

2. The LED lamp is connected to incandescent or halogen dimmer

Dimmable LED lights can often not be dimmed (or not far back) or start blinking with a light bulb/halogen dimmer. This is because the minimum power of these 'normal' dimmers is often still too high for the low total wattage of the LED lamps.

Solution: Connect an LED dimmer to your dimmable LED lamps.

3. The LED lamp is connected to the wrong type of LED dimmer (phase cut/cut)

Dimmable LED lamps are equipped with a dimmable driver, which always works on the dimming technique 'phase cut-off' or 'phase cut-off'. A LED dimmer always uses one of these 2 dimming techniques. Have you connected your LED lamps to the wrong type of LED Dimmer? This cannot cause damage, but it can cause unstable light.

Phase cut-off = Leading edge
Phase cut-off = Trailing edge

Solution: Did you buy the wrong type of LED dimmer from us? Then you can exchange it for the right model. Have you purchased another brand of LED dimmer and you do not know which one you need? Call or email us with the type of dimmer you have purchased and the brand of LED lamps you want to connect. Or ask your question below in response.

Tip: Perhaps the article “ Which LED dimmer do I need? "Help you further.

4. LED dimmer settings

The big advantage of an LED dimmer with setting possibilities is that you can use it to dim your LED lamps further and more stable because you can adjust them to your specific situation. A LED dimmer without setting options may, therefore, cause flashing LED lights or the ability to dim far back.
Do you have such a LED dimmer with, for example, a potentiometer (s)?

Solution: Check whether the COARSE (and FINE) potentiometer are set so that the light remains stable. Turn the potentiometer (s) as far as possible to the point where your LED lights give as little light as possible but still remain stable. That is the optimum dimming ability of your LED lamps, provided you, of course, have the right dimmer ( phase cut or phase cut ). Are you turning the potentiometer even further? Then your LED lights will blink.

5. An LED lamp (low voltage) is connected to the wrong transformer

Do you have low-voltage LED lamps (eg 12V or 24V) connected to your traditional halogen transformer or an LED transformer that does not meet the minimum power? Then your LED lights can start blinking.

Solution: Connect your 12V / 24V LED lamps to an LED transformer. Make sure that the total wattage of the connected LED lamps remains within the minimum and maximum power of the LED transformer.

Do you want to dim 12V LED? Then go for dimmable led lamps 12V + dimmable led transformer + led dimmer for 12v led .

6. Fluctuations in the network

Fluctuations in the grid, also called ripple and peak voltages, can be caused by:

   - Other (large) devices on the same group

   - Leakage current

Other devices on the same group
If other (large) devices in the same group switch on or off, this may cause a small flash in the light of the LED lights or the lights may light up / down. This is because LED lamps are very sensitive to interference pulses from outside. A typical example is turning on an air conditioning, freezer or fridge.

Leakage current
Another cause of flickering LED lamps can be leakage current. A very small amount of current/voltage is lost, caused by wiring and other electrical components. Good insulation of this material can limit leakage, but it cannot always be 100% prevented.

Solution: Do not connect other (large) devices to the same group as the LED lighting or place a stabilizer for the group of LED lamps. Is this not possible? Then buy LED lamps and an LED dimmer with a good power filter.
All our LED lamps and LED dimmers are equipped with a VDR, which absorbs peak voltages. The LED TLs Pro and LED panels Pro are provided with extra protection, so that interference pulses from the outside have less chance.

7. Defective driver

Have your LED lights never blinked and do they suddenly give a (regular) flicker? The driver of your LED lamp is probably defective. This can happen due to overheating, for example, because of the max. Ambient temperature is exceeded.

Solution: A new lamp or driver must be installed. In the case of an external driver, only the driver can be replaced. Is the driver processed in the LED lamp? Then you have to replace the entire lamp. Make sure that the temperature in which the lamp & driver are located does not exceed 50⁰C.

Which LED dimmer do I need

Which LED dimmer do I need The LED lighting cannot simply be connected to every LED dimmer. But "Which LED dimmer do I need?" You may wonder. Based on 2 questions, I will show you which  LED dimmer you need. Of course, you can also call us for advice (0314-840165). Which LED dimmer you need depends on the type of LED lamps you have.      1) Are your LED lamps dimmable?      2) If so, do they work on phase cutting (leading edge / RL) or phase cutting (trailing edge / RC)? If you know the answer to this, it is the dimmer that you are looking for: Led dimmer phase cut-off or Led dimmer phase cut-off. If you do not know the answer to this, read on or contact us. 1. Dimmable Led lighting is not dimmable as standard. It must be clearly stated on the packaging or on the purchase receipt that the LED lamps are dimmable. Is this not the case? Then your LED lights cannot be dimmed. Is this the case? Then you work LED lamps on an LED dimmer phase ...
