Lots of the problems that affect the efficiency of LED panels are universal to all LEDs, reminiscent of flickering, glowing, burnout and buzzing. For detailed info on the way to combat these typical problems with LEDs, try our article How you can Stop Your LEDs from Flickering, Buzzing, Glowing and Burning Out.

There are some issues that specifically have an effect on LED panels. The content material on this page takes a better have a look at these:

Quick LED panel drawback detection

If your LED panel is failing and you are unsure of the fault, there may be a quick and diagnosis you are able to do. Try switching on the LED panel and test the desk under.

Common LED problems and their probably causes


Likely trigger

The LED panel doesn’t illuminate in any respect

The LED panel flashes

Driver failure

Detecting the problem and the probably trigger is barely half the battle. Within the sections under, you will be able to find the options to these problems.

Problems with drivers and voltage conversion

An LED driver regulates the amount of energy that flows by a lighting system. Drivers convert the AC power from the mains provide to the DC power required to run LED panels and subsequently prevent energy surges. LED drivers are small units that are wired to the LED panel. They play an analogous role to ballasts in fluorescent lights.

Drivers are vulnerable to overheating. Even drivers that work appropriately will be affected by heat over time. However using low cost, low quality drivers or the mistaken driver will mean it is at larger threat of overheating sooner.

It’s because the current flowing by the system isn’t saved at a continuing level, so the excess heat generated impacts the driver’s performance.

– Voltage from the mains energy supply is (240v), a driver converts this to 12v or 24v to run the panel correctly. If the driver isn’t working correctly then it doesn’t convert this current and retains the voltage at a continuing stage. This means the bulb will flicker and the system won’t react to overloads which implies the panels are at an increased risk of burnout.

– In case your LED panel isn’t working at all then the most probably reason for that is defective inner wiring the place the wiring will not be linked to the driver appropriately.

– Although not technically a fault with the wiring, fitting dimmable LED panels with an incompatible dimmer swap will cause flickering.


– Ensure your LED panels are appropriate with the circuits, power provide and gentle switches they are running off.

– Invest in back-lit or central-lit panels (where the LED chips are mounted onto the panel, relatively than the sting of the panel), as these panels function built-in drivers which will help to cut back the issues with drivers outlined above.

– Ask an electrician to examine that the wiring in the lighting system is fitted appropriately.

Problems with poor insulation, ventilation and overheating

LED panels should be correctly insulated to make sure the heat they produce is dissipated correcting in order that they don’t overheat. Quality LED panels are fitted with a heat sink made from a conductive metallic (usually aluminium) which transfers excess heat away from the panel. If this heat sink is low high quality, poorly fitted or not fitted in any respect then the excess heat could cause the LED chips within the panel to burnout.

Not all LEDs are suitable to be fitted into enclosed fixtures. Fitting an unsuitable LED into an enclosed fitting can cause it to overheat because the bulb won’t have the appropriate heat sink. This isn’t as a lot of a difficulty with LED panels as they are often designed to fit in enclosed fixtures, nonetheless, it’s all the time price checking the panels are suitable to be installed into recessed fittings.

– Poor high quality or defective heat sinks may cause LED panels to overheat and burnout.- If the LED panel driver is faulty then this may name the panel to overheat (see issues with drivers and voltage conversion above).


– Only purchase LED panels with a appropriately fitted aluminium heat sink. Make sure the panel is designed to be installed right into a recessed fitting.

Problems with low quality LEDs

LED panels are dearer than traditional fluorescent tubes and for this reason shoppers may choose cheap, low high quality LEDs and anticipate the identical performance from them as the leading manufacturers. Low high quality LED panels often feature inferior parts that aren’t tested properly.

LED panels function a lot of parts; if any of those components are low quality or faulty it could actually have an effect on the general efficiency of the LED panels.


– Frame-normally fabricated from aluminium, the frame accommodates the sunshine throughout the panel. – If the frame is just too mild or is product of a material aside from aluminium (low cost LED panels often characteristic a plastic body), then this could create excess heat and enhance the danger of burn out from overheating.

– Low quality chips may cause plenty of problems together with the panel changing into dim or the colour quality being compromised.- If low high quality LED chips are utilized in a panel this will produce a ‘blue’ hue which can make a room look chilly.

– If it’s not fitted accurately then this can affect on the amount of light and the angle of the light reaching the diffuser.

– A low quality diffuser, LED panel lighting made from acrylic or PMMA moderately than polycarbonate, won’t distribute light as evenly.- Overtime, plastic diffusers can discolour at the edges and turn yellow, lowering the quality of mild produced by the LED panel.

– Issues with the reflector plate may cause glare.

– A poor quality heat sink will imply not enough heat is dissipated from the LED chips which can cause the chips to burnout.- Cheap plastic heat sinks don’t work as effectively as metallic heat sinks and might reduce the life expectancy of the LEDs in the panel.

– The better the again cover matches the frame, the better the heat dissipation which suggests the panel is prone to final longer.

It’s very tough to establish whether an LED panel is excessive or low quality till it’s installed. You won’t essentially know you’ve gotten a low high quality LED till it burns out shortly or produces poor high quality light for example.

Solution: How to pick a high quality LED panel

– Choose a panel that’s at least £15-30 or £30 – 50 for increased finish. In relation to LED panels price does point out quality. Panels beneath £12 will go yellow, ripple or warp much faster.

– Avoid panels that only have a two 12 months warranty. They solely have a two yr warranty because they don’t seem to be constructed to last! Good quality panels will last longer than this.

– Choose a panel that has a mild information plate made out of acrylic (PMMA) or methyl styrene (MS).

– Choose a panel that’s finished with powder coating as opposed to paint.

– Search for a nicely-constructed body.

– Choose a trusted brand. If you loved this write-up and you would like to obtain more data with regards to ceiling light panel panel light (https://blogfreely.net/) kindly visit our site. There are plenty of them out there, listed here are only a few of our favourites: – Britesource

– Philips

– Osram

– Toshiba

Methyl styrene is the perfect material to decide on for the light information plate (LGP)

There are a couple of minor indications of quality corresponding to a panel that’s completed with powder coating quite than paint and a effectively-constructed body however, the actual marker of high quality comes all the way down to the material used to make the sunshine guide plate.

There are three supplies generally used to make an LGP:


– Polystyrene (PS)

– MS

We recommend choosing an LGP product of MS.

PMMA has the perfect gentle transmission and durability however can also be probably the most expensive – it’s a excessive-high quality product, but not probably the most reasonably priced.

PS gives good transmission, but it surely tends to show yellow over time resulting from put on and tear and the effects of heat. It is a well known concern in the business and is often why these panels have a guaranty of only 2 years. Over time they may ripple of turn out to be warped because they aren’t sturdy sufficient to handle regular heat exposure. It is the most affordable possibility of the three, however we might consider it a low-high quality choice.

MS is a mix of PMMA and PS. It gives excellent mild transmission and can also be durable, however at a decrease worth, is essentially the most value-effective answer.

Problems with LED panels failing early


LEDs are extremely well-liked as a result of they’re known to last for much longer than customary halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, meaning they need to last an incredibly very long time. This kind of longevity makes LED price price-efficient and environmentally pleasant.
