Common Problems With LED Panels And The Way To Repair Them

A lot of the problems that have an effect on the efficiency of LED panels are common to all LEDs, equivalent to flickering, glowing, burnout and buzzing.

In case your LED panel is failing and you’re undecided of the fault, there’s a fast and prognosis you are able to do. Try switching on the LED panel and test the table under.

Common LED issues and their seemingly causes


Likely cause

The LED panel doesn’t illuminate at all

The LED panel flashes

Driver failure

If solely some of the LEDs within the panel are lit

LED failure

Detecting the issue and the seemingly trigger is barely half the battle. In the sections under, you may be able to find the options to those problems.

Problems with drivers and voltage conversion

An LED driver regulates the quantity of power that flows by means of a lighting system. Drivers convert the AC power from the mains supply to the DC power required to run LED panels and therefore stop power surges. If you adored this information in addition to you would like to acquire more info relating to LED panel light ( kindly check out the webpage. LED drivers are small models that are wired to the LED panel. They play an analogous role to ballasts in fluorescent lights.

Drivers are susceptible to overheating. Even drivers that work correctly might be affected by heat over time. However using low-cost, low quality drivers or the wrong driver will mean it’s at better danger of overheating sooner.

It’s because the current flowing through the system isn’t stored at a relentless level, so the surplus heat generated impacts the driver’s efficiency.

– Voltage from the mains energy provide 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 constant level. This implies the bulb will flicker and the system won’t react to overloads which implies the panels are at an elevated risk of burnout.

– If your LED panel isn’t working in any respect then the most certainly purpose for that is faulty inside wiring where the wiring is just not related to the driver accurately.

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


– Ensure your LED panels are appropriate with the circuits, Panel LED ceiling light panel energy supply and light switches they’re running off.

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

– Ask an electrician to examine that the wiring within the lighting system is fitted accurately.

Problems with poor insulation, ventilation and overheating

LED panels should be properly insulated to ensure the heat they produce is dissipated correcting so they don’t overheat. Quality LED panels are fitted with a heat sink made from a conductive metal (usually aluminium) which transfers excess heat away from the panel. If this heat sink is low quality, poorly fitted or not fitted in any respect then the excess heat can 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 suitable heat sink. This isn’t as a lot of a difficulty with LED panels as they’re usually designed to slot in enclosed fixtures, nonetheless, it’s always worth checking the panels are suitable to be put in into recessed fittings.

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


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

Problems with low high quality LEDs

LED panels are more expensive than conventional fluorescent tubes and because of this shoppers might select low-cost, low high quality LEDs and anticipate the identical efficiency from them as the main manufacturers. Low high quality LED panels typically function inferior components that aren’t examined correctly.

LED panels feature various elements; if any of these parts are low high quality or defective it might probably have an effect on the overall efficiency of the LED panels.


– Frame-usually made from aluminium, the body accommodates the light within the panel. – If the body is too gentle or is made of a cloth aside from aluminium (low-cost LED panels typically characteristic a plastic frame), then this could create excess heat and improve the danger of burn out from overheating.

– Low quality chips can cause numerous issues including the panel turning into dim or the color high quality being compromised.- If low quality LED chips are used in a panel this will produce a ‘blue’ hue which could make a room look cold.

– If it’s not fitted correctly then this can influence on the amount of mild and the angle of the sunshine reaching the diffuser.

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

– Issues with the reflector plate may 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 might cut back the life expectancy of the LEDs within the panel.

– The better the back cowl suits the body, the higher the heat dissipation which implies the panel is prone to last longer.

It’s very difficult to determine whether an LED panel is excessive or low high quality until it is installed. You won’t necessarily know you will have a low high quality LED till it burns out quickly or produces poor high quality gentle for example.

Solution: How to pick a top quality LED panel

– Choose a panel that’s no less than £15-30 or £30 – 50 for higher finish. In the case of LED panels price does indicate quality. Panels under £12 will go yellow, ripple or warp much quicker.

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

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

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

– Search for a properly-constructed frame.

– Choose a trusted model. There are plenty of them out there, listed below are only a few of our favourites: – Britesource

– Philips

– Osram

– Toshiba

Methyl styrene is the perfect materials to choose for the sunshine guide plate (LGP)

There are a couple of minor indications of quality similar to a panel that is completed with powder coating relatively than paint and a properly-constructed body however, the true marker of quality comes right down to the material used to make the sunshine information plate.

There are three materials commonly used to make an LGP:


– Polystyrene (PS)

– MS

We suggest choosing an LGP made from MS.

PMMA has the very best mild transmission and durability however can also be probably the most costly – it’s a excessive-high quality product, but not essentially the most reasonably priced.

PS presents good transmission, nevertheless it tends to show yellow over time because of put on and tear and the results of heat. It’s a widely known issue in the industry and is often why these panels have a guaranty of only 2 years. Over time they also can ripple of change into warped as a result of they aren’t strong enough to handle regular heat publicity. It is the cheapest possibility of the three, LED panel light however we’d consider it a low-quality alternative.

MS is a mixture of PMMA and PS. It supplies very good mild transmission and is also durable, but at a decrease worth, is essentially the most cost-effective resolution.

Problems with LED panels failing early


LEDs are incredibly popular because they are known to final for much longer than commonplace halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, which means they need to last an incredibly very long time. This sort of longevity makes LED price value-effective and environmentally friendly.
