If your LED panel is failing and you’re unsure of the fault, there is a fast and prognosis you can do. Try switching on the LED panel and verify the table under.
Common LED problems and their seemingly causes

Likely cause
The LED panel doesn’t illuminate at all
The LED panel flashes
Driver failure

LED failure
Detecting the problem and the possible trigger is barely half the battle. In the sections below, you’ll 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 through a lighting system. Drivers convert the AC power from the mains provide to the DC energy required to run LED panels and due to this fact forestall energy surges. LED drivers are small units which can be wired to the LED panel. They play the same role to ballasts in fluorescent lights.
Drivers are susceptible to overheating. Even drivers that work accurately will be affected by heat over time. However using low cost, low high quality drivers or the fallacious driver will mean it’s at better threat of overheating sooner.
It’s because the current flowing via the system isn’t saved at a relentless level, so the surplus 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 appropriately. If the driver isn’t working appropriately then it doesn’t convert this present and retains the voltage at a constant stage. This implies the bulb will flicker and the system won’t react to overloads which suggests the panels are at an increased threat of burnout.
– If your LED panel isn’t working in any respect then the almost definitely cause for that is faulty inner wiring where the wiring is just not 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.
Solutions
– Ensure your LED panels are compatible with the circuits, power supply and mild switches they are running off.
– Spend money on back-lit or central-lit panels (where the LED chips are mounted onto the panel, reasonably than the edge of the panel), as these panels characteristic built-in drivers which may help to reduce the issues with drivers outlined above.
– Ask an electrician to verify that the wiring within the lighting system is fitted accurately.
Problems with poor insulation, ventilation and overheating
LED panels must be correctly insulated to make sure the heat they produce is dissipated correcting so they don’t overheat. Quality LED light panel 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 at all then the surplus 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 suitable heat sink. This isn’t as a lot of a problem with LED panels as they are normally designed to fit in enclosed fixtures, nevertheless, it’s always value checking the panels are appropriate to be put in into recessed fittings.
– Poor quality or faulty heat sinks can cause LED panels to overheat and burnout.- If the LED panel driver is faulty then this also can call the panel to overheat (see issues with drivers and voltage conversion above).
Solution
– Only buy LED panels with a accurately fitted aluminium heat sink. Ensure 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 that reason customers might choose low-cost, low high quality LEDs and expect the same efficiency from them because the leading manufacturers. Low high quality LED panels often feature inferior elements that aren’t tested correctly.
LED panels function a lot of elements; if any of these parts are low high quality or faulty it may have an effect on the general efficiency of the LED panels.
Problems
– Frame-normally product of aluminium, the frame comprises the light inside the panel. – If the body is too light or is made from a fabric apart from aluminium (low-cost LED panels usually feature a plastic body), then this might create excess heat and improve the danger of burn out from overheating.
– Low high quality chips may cause a number of problems together with the panel changing into dim or the color high quality being compromised.- If low high quality LED chips are utilized in a panel this could produce a ‘blue’ hue which can make a room look chilly.
– If it’s not fitted correctly then this may impression on the amount of gentle 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 gentle as evenly.- Overtime, plastic diffusers can discolour at the edges and switch yellow, decreasing the standard of mild produced by the LED panel.
– Issues with the reflector plate can cause glare.
– A poor Panel LED light high quality heat sink will imply not sufficient heat is dissipated from the LED chips which may cause the chips to burnout.- Cheap plastic heat sinks don’t work as successfully as steel heat sinks and might reduce the life expectancy of the LEDs within the panel.
– The better the again cover matches the frame, the higher the heat dissipation which means the panel is prone to last longer.
It’s very difficult to establish whether an LED panel is high or low quality until it is put in. You won’t essentially know you might have a low high quality LED until it burns out rapidly or produces poor quality mild for instance.
Solution: How to pick a top quality LED panel
– Choose a panel that is at least £15-30 or £30 – 50 for larger finish. With regards to LED panels worth does indicate high quality. Panels beneath £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 don’t seem to be built to final! Good high 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 ceiling panel light that is finished with powder coating versus paint.

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

Methyl styrene is the most effective materials to decide on for the sunshine information plate (LGP)
There are a few minor indications of high quality corresponding to a panel that is completed with powder coating reasonably than paint and a well-constructed frame however, the actual marker of high quality comes down to the material used to make the light information plate.
There are three materials generally used to make an LGP:
– PMMA
– Polystyrene (PS)
– MS
We recommend selecting an LGP made from MS.
PMMA has the most effective gentle transmission and sturdiness however is also the most expensive – it is a high-high quality product, however not probably the most affordable.
PS provides good transmission, but it tends to show yellow over time resulting from put on and tear and the results of heat. It is a well known difficulty in the industry and is usually why these panels have a guaranty of only 2 years. Over time they also can ripple of turn out to be warped because they aren’t strong enough to handle regular heat publicity. It’s the most cost effective possibility of the three, however we’d consider it a low-high quality selection.
MS is a mixture of PMMA and PS. It provides superb gentle transmission and can also be durable, but at a decrease worth, is the most value-efficient solution.

Overview
LEDs are extremely common because they are identified to last much longer than customary halogen or fluorescent bulbs. Some LEDs can final over 15,000 hours, that means they need to last an incredibly very long time. This type of longevity makes LED value value-efficient and environmentally friendly.
