Flickering of light can cause damage to the normal human eye. Therefore, a person usually witnesses a flickering light almost two or three times in a single day. When you ensure switching from Incandescent or halogen bulbs to advanced, energy-sufficient LED bulbs and connect with a dim switch. Whenever someone tries to ensure dimming the LED lights the newly installed LEDs will flicker. It is not able to fulfill your requirements like a traditional bulb mostly does. Moreover, when the dimmer is not used properly the chances of flickering become more. If you have any queries regarding dimmable led flash then go through properly this article.
Is flickering referred dangerous for health?
One thing you must need to understand about flickering. There are two types of flickering and which are given as,
- Visible flickering
- Invisible flickering
Such flickering which falls into the observation of a normal human eye is called visible flickering. On the other hand, a flickering that does not fall into the observation of a normal human eye is called invisible flickering. One thing is common in both types of flickering. Because both can cause damage to the health of an individual.
Health issues caused by Flickering:
There are numerous health issues come out as a result of harmful flickering. Some of the prominent health issues are given as,
- Epileptic seizures
- Vision impairment
- Lack of concentration
Which factors take Dimmable LED to flicker?
Traditional bulb always converts electricity into heat and light with the help of filament. While, on the other hand, the LED bulb converts electricity directly into light for illuminating. Therefore, the chances of flickering impact LED bulbs more than a particular sort of traditional bulb. In addition to these, a traditional bulb converts electricity into two parts in which heat is the main factor. This heat protects a traditional bulb from unnecessary and harmful flickering. Moreover, it is a slow process that suddenly gets heat and cools down instantly.
The LED bulb is affected because it is highly sensitive to voltage fluctuations. However, the LED bulb is impressive in quality. Because the advanced version has incorporated a lot of features in which managing voltage fluctuations are prominent in all. They included astonishing advancements in the form of installing dimmers to overcome unwanted flickering. People should be able to make the difference between dimmer switch LED bulbs and non-dimmer LED bulbs.
LED bulb flickering in the presence of Dimmer
When LED flashes are used to keep in conjunction with a dimmer switch then problems like flickering come out. Moreover, it can ensure universal impacts, and the following are given,
Installation of Dimmable Bulb:
You should make ensure that either your LED bulb is dimmable or non-dimmable. Because you mostly use dimmer switches to dim non-dimmable light. On the other hand, a traditional bulb that produces heat is dimmed naturally. On the contrary, when it comes to non-dimmable light then special kind of semiconductor is used by LED bulbs. But following glitches spread around in results and which are given as,
- Strobing and flashing
- Humming sounds or buzzing
- Light flickers or glows in the absence of light is called Ghosting
There are chances for a dimmable LED to flash even in the case of a non-compatible dimmer switch. However, whenever an individual uses an old version of the dimmer switch. Then it is most likely to cause uncontrollable flickering in this regard. Moreover, it also produces unwanted buzzing sounds therefore, the old dimmer is not suggested to use in in the future.
Therefore, a compatible dimmer is established to resolve this trouble. Because it is specially designed for LEDs and low-wattage LED bulbs are easy to handle nowadays. Nevertheless, there is a variety of dimmer LEDs available on the market.
The orbit of wattage:
Every dimmer is designed by keeping in view the different ratings. These wattage ratings depend upon the type of load. For instance, preferable able ratings are between 600W and 1000W for incandescent. If the dimmer carries the chain of lights then it is considered overloading. Such overloading leads a dimmer LED bulb to unwanted flickering. However, 70 to 80% ratings are preferable and fall into the orbit of wattage. If you want to abandon this problem then remove some LEDs from the circuit to maintain the load.
Usage of a dimmer that incorporates a neutral wire:
The usage of a neutral wire dimmer prevents unwanted leakage which holds current. In addition, whenever you turn off the switch, flickering is easy to remove. Furthermore, when there is a ground wire the chances of small leaking are more which causes unnecessary flickering.
Upgrading bulb or fixture:
When you ensure the replacement of the low-quality lamp with an alternative one then flickering can be controlled. On the contrary, when you prefer cheaper LED then the chances of flickering become higher.
LED flickering in the absence of a Dimmer
When an LED bulb is replaced with a faulty one then flickering occurs as a result. The following are the impacts given,
Most of the time, flickering comes up whenever a damaging or outdated wire is used. Moreover, loss of connections and the installation of wiring in the wrong way may cause unnecessary flicking. Therefore, a dimmable LED flash is used to overcome this situation. The possibility is always there whether your wiring connection is in the wall or outside the home.
The factor of Transformer:
When an inefficient transformer is installed to provide current for the household sector, the chances of flickering are exponentially high due to voltage imbalance. On the contrary, when the load is high on the transformer then it causes unwanted flickering in this regard.
Imbalance flow of current by large appliances:
When people try to switch on heavy appliances like air conditioners, pumps, heaters, and vice versa. Then the transformer can’t maintain the flow of current to the different networks. This is the one effect but the major comes out in the form of unwanted flickering.
When you install several LED bulbs on the same circuit then it is considered overloading. A circuit as we discussed above is overloaded when people switch on large appliances. Therefore, you will have to avoid the functioning of some appliances to counter flickering. Therefore, a dimmable LED flash bulb is necessary to use.
The factor of Residual Electricity:
Sometimes, flickering occurs even when you switch off large appliances. This happens as a result of unwanted residual electricity. Because residual electricity remains for a while even after switching off appliances.
When wiring is not installed properly. Then it triggers the LED to cause a flicker in the circuit. Nevertheless, if you manage to use a dimmable LED flash bulb then the problem is easy to encounter.
Leaking current form switch:
Most a switch is not made for bearing a heavy load of large appliances. Therefore, leakage occurs which leads LED to unwanted flickering.
It is concluded that a dimmable LED flash is mandatory when incorrect wiring is installed. Because an unwanted flickering comes out as a result. It incorporates a lot of alternatives to avoid such flickering. However, if you ensure the usage of a dimmable LED flash then you will easily tackle every problem.
