Common Problems With LED Panels And How To Fix Them

Many of the problems that have an effect on the performance of LED panels are universal to all LEDs, akin to flickering, glowing, burnout and buzzing. For detailed information on tips on how to combat these typical issues with LEDs, take a look at our article Tips on how to Stop Your LEDs from Flickering, Buzzing, Glowing and Burning Out.

There are some issues that specifically affect LED panels. The content material on this page takes a more in-depth have a look at these:

If your LED panel is failing and you are undecided of the fault, there’s a quick and analysis you can do. Try switching on the LED panel and examine the desk below.

Common LED problems and their likely causes


Likely cause

The LED panel does not illuminate in any respect

The LED panel flashes

Driver failure

LED failure

Detecting the issue and the probably trigger is simply half the battle. Within the sections beneath, you may be able to find the options to these problems.

Problems with drivers and voltage conversion

An LED driver regulates the amount of power that flows via a lighting system. If you have any sort of inquiries regarding where and how to utilize ceiling light panel [], you can call us at our web-page. Drivers convert the AC power from the mains supply to the DC energy required to run LED panels and due to this fact stop energy surges. LED drivers are small models which are wired to the LED panel. They play an identical role to ballasts in fluorescent lights.

Drivers are vulnerable to overheating. Even drivers that work accurately might be affected by heat over time. However utilizing cheap, low high quality drivers or the mistaken driver will mean it is at higher threat of overheating sooner.

This is because the current flowing via the system isn’t kept at a constant stage, so the surplus heat generated impacts the driver’s performance.

– Voltage from the mains power provide is (240v), a driver converts this to 12v or 24v to run the panel accurately. If the driver isn’t working appropriately then it doesn’t convert this present and retains the voltage at a continuing degree. This implies the bulb will flicker and the system won’t react to overloads which implies the panels are at an increased threat of burnout.

– If your LED panel isn’t working at all then the probably purpose for that is faulty inside wiring where the wiring is not linked to the driver appropriately.

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


– Ensure your LED panels are compatible with the circuits, energy provide and gentle switches they’re working off.

– Invest in again-lit or central-lit panels (the place the LED chips are mounted onto the panel, quite than the sting of the panel), as these panels function constructed-in drivers which will help to cut back the problems with drivers outlined above.

– Ask an electrician to check that the wiring in the lighting system is fitted correctly.

Problems with poor insulation, ventilation and overheating

LED panels have to be correctly insulated to make sure the heat they produce is dissipated correcting so that they don’t overheat. Quality LED panels are fitted with a heat sink made from a conductive steel (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 surplus heat could cause the LED chips in the panel to burnout.

Not all LEDs are appropriate to be fitted into enclosed fixtures. Fitting an unsuitable LED into an enclosed fitting may cause it to overheat as the bulb won’t have the appropriate heat sink. This isn’t as much of a difficulty with LED panels as they are normally designed to fit in enclosed fixtures, however, it’s all the time value checking the panels are appropriate to be put in 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 call the panel to overheat (see problems with drivers and voltage conversion above).


– Only purchase LED panels with a accurately fitted aluminium heat sink. Ensure the panel is designed to be put in into a recessed fitting.

Problems with low quality LEDs

LED panels are dearer than conventional fluorescent tubes and for this reason customers could select low cost, low quality LEDs and anticipate the same performance from them as the leading brands. Low quality LED panels often characteristic inferior elements that aren’t examined correctly.

LED panels function a lot of components; if any of those components are low quality or defective it could affect the general performance of the LED panels.


– Frame-often made from aluminium, the frame incorporates the light throughout the panel. – If the frame is too mild or is product of a cloth apart from aluminium (cheap LED panels often feature a plastic body), then this could create excess heat and improve the risk of burn out from overheating.

– Low quality chips could cause plenty of issues including the panel becoming dim or the colour quality being compromised.

– If low quality LED chips are utilized in a panel this can produce a ‘blue’ hue which could make a room look chilly.

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

– A low high quality diffuser, made from acrylic or PMMA reasonably than polycarbonate, won’t distribute mild as evenly.

– Overtime, plastic diffusers can discolour on the edges and switch yellow, lowering the quality of gentle produced by the LED panel.

– Issues with the reflector plate can cause glare.

– A poor high quality heat sink will mean not enough heat is dissipated from the LED chips which may cause the chips to burnout.

– Cheap plastic heat sinks don’t work as effectively as metal heat sinks and may cut back the life expectancy of the LEDs in the panel.

– The better the back cover matches the body, ceiling led panel light the higher the heat dissipation which means the panel is prone to last longer.

It’s very tough to determine whether or ceiling light panel not an LED panel is excessive or low high quality till it’s installed. You won’t essentially know you have a low high quality LED until it burns out rapidly or produces poor high quality light for example.

Solution: How to pick out a high quality LED panel

– Choose a panel that’s at the least £15-30 or £30 – 50 for increased finish. When it comes to LED panels price does point out quality. Panels under £12 will go yellow, ripple or warp a lot faster.

– Avoid panels that only have a two 12 months warranty. They solely have a two year guarantee as a result of they are not built to last! Good quality panels will final longer than this.

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

– Choose a panel that is completed with powder coating versus paint.

– Look for a properly-constructed frame.

– Choose a trusted brand. There are many them out there, listed here are just a few of our favourites: – Britesource

– Philips

– Osram

– Toshiba

Methyl styrene is the perfect materials to decide on for the sunshine information plate (LGP)

There are a couple of minor indications of high quality such as a panel that is completed with powder coating reasonably than paint and a nicely-constructed frame nonetheless, the real marker of quality comes right down to the material used to make the light information plate.

There are three supplies generally used to make an LGP:


– Polystyrene (PS)

– MS

We suggest choosing an LGP fabricated from MS.

PMMA has the best light transmission and durability however is also the most costly – it’s a excessive-high quality product, but not the most affordable.

PS gives good transmission, nevertheless it tends to show yellow over time as a consequence of wear and tear and the consequences of heat. It is a widely known challenge in the trade and is often why these panels have a warranty of only 2 years. Over time they can even ripple of turn out to be warped because they aren’t robust sufficient to handle normal heat exposure. It’s the cheapest choice of the three, however we’d consider it a low-high quality selection.

MS is a mix of PMMA and PS. It provides superb light transmission and can be durable, but at a lower value, is the most cost-effective answer.

Problems with LED panels failing early


LEDs are extremely well-liked because they are recognized to last for much longer than normal halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, meaning they need to final an extremely long time. This type of longevity makes LED cost cost-effective and environmentally pleasant.
