A lot of the issues that have an effect on the efficiency of LED panels are universal to all LEDs, comparable to flickering, glowing, burnout and buzzing. For detailed information on how you can combat these typical issues with LEDs, take a look at our article Learn how to Stop Your LEDs from Flickering, Buzzing, Glowing and Burning Out.

Quick LED panel downside detection
In case your LED panel is failing and you are not sure of the fault, there may be a fast and analysis you can do. Try switching on the LED panel and test the desk under.
Common LED problems and their probably causes

Detecting the issue and the possible trigger is just half the battle. Within the sections below, you can be able to find the options to those issues.
Problems with drivers and voltage conversion
An LED driver regulates the quantity of energy that flows by a lighting system. Drivers convert the AC energy from the mains provide to the DC energy required to run LED panels and subsequently forestall energy surges. LED drivers are small items which can be wired to the LED panel. They play an analogous role to ballasts in fluorescent lights.
Drivers are weak to overheating. Even drivers that work correctly shall be affected by heat over time. However utilizing low cost, low quality drivers or the fallacious driver will mean it is at greater risk of overheating sooner.
It’s because the present flowing by way of the system isn’t saved at a constant level, so the surplus heat generated impacts the driver’s efficiency.
– 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 correctly then it doesn’t convert this present and keeps the voltage at a constant stage. This implies the bulb will flicker and the system won’t react to overloads which means the panels are at an elevated threat of burnout.
– If your LED panel isn’t working at all then the most probably purpose for this is faulty internal wiring where the wiring isn’t connected to the driver correctly.
– Although not technically a fault with the wiring, fitting dimmable LED panels with an incompatible dimmer switch will trigger flickering.
Solutions
– Ensure your LED panels are appropriate with the circuits, power provide and gentle switches they’re working off.

– Ask an electrician to check that the wiring in the lighting system is fitted accurately.
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 metal (often 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 excess heat may 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 can 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’re usually designed to fit in enclosed fixtures, however, it’s at all times value checking the panels are suitable to be put in into recessed fittings.
– Poor quality or defective heat sinks could cause LED panels to overheat and burnout.- If the LED panel driver is defective then this may also call the panel to overheat (see issues with drivers and voltage conversion above).
Solution
– Only purchase LED panels with a accurately fitted aluminium heat sink. Ensure the panel is designed to be installed into a recessed fitting.
Problems with low high quality LEDs
LED panels are more expensive than traditional fluorescent tubes and for this reason consumers could select low-cost, low quality LEDs and anticipate the identical efficiency from them as the main brands. Low high quality LED panels often feature inferior components that aren’t tested properly.
LED panels characteristic a variety of components; if any of these parts are low quality or faulty it could actually affect the general efficiency of the LED panels.
Problems
– Frame-usually fabricated from aluminium, the frame incorporates the sunshine within the panel. – If the body is too mild or is made of a fabric aside from aluminium (low cost LED panels usually feature a plastic body), then this might create excess heat and increase the chance of burn out from overheating.
– Low quality chips could cause quite a lot of problems including the panel changing into dim or the color quality being compromised.- If low 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 appropriately then this will influence on the quantity of mild and the angle of the light reaching the diffuser.
– A low quality diffuser, made from acrylic or PMMA somewhat than polycarbonate, won’t distribute gentle as evenly.- Overtime, plastic diffusers can discolour on the edges and turn yellow, lowering the quality of light produced by the LED panel.
– Issues with the reflector plate can cause glare.
– A poor quality heat sink will mean not enough heat is dissipated from the LED chips which could cause the chips to burnout.- Cheap plastic heat sinks don’t work as effectively as metallic heat sinks and may scale back the life expectancy of the LEDs within the panel.
– The better the back cover fits the frame, the better the heat dissipation which implies the panel is likely to last longer.
It’s very troublesome to identify whether an LED panel is high or low high quality until it’s installed. You won’t essentially know you will have a low high quality LED till it burns out shortly or produces poor quality gentle for instance.
Solution: How to select a top quality LED panel
– Choose a panel that’s at least £15-30 or £30 – 50 for greater end. In the case of LED panels worth does point out quality. Panels below £12 will go yellow, ripple or warp much faster.
– Avoid panels that solely have a two 12 months guarantee. They only have a two 12 months guarantee because they don’t seem to be built to final! 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 is completed with powder coating as opposed to paint.
– Look for a effectively-constructed body.
– 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 most effective materials to choose for the light guide plate (LGP)
There are a few minor indications of high quality such as a panel that’s finished with powder coating rather than paint and a effectively-constructed body nonetheless, the true marker of quality comes down to the material used to make the light information plate.
There are three supplies commonly used to make an LGP:
– PMMA
– Polystyrene (PS)
– MS
We recommend selecting an LGP fabricated from MS.
PMMA has one of the best gentle transmission and sturdiness however can also be probably the most expensive – it is a high-high quality product, however not probably the most inexpensive.
PS provides good transmission, however it tends to turn yellow over time as a result of put on and tear and the consequences of heat. It’s a well known problem within the industry and is commonly why these panels have a warranty of only 2 years. Over time they may ripple of turn out to be warped because they aren’t robust enough to handle regular heat publicity. It’s the cheapest possibility of the three, but we might consider it a low-high quality selection.
MS is a mix of PMMA and PS. It offers superb light transmission and can also be durable, but at a lower value, is essentially the most price-effective solution.

Overview
LEDs are extremely in style because they are recognized to last much longer than commonplace halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, which means they need to last an extremely very long time. This form of longevity makes LED price cost-efficient and environmentally pleasant.
