Problems with drivers and voltage conversion

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

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

It’s because the present flowing by means of the system isn’t stored at a constant 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 accurately. If the driver isn’t working accurately then it doesn’t convert this present 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 elevated risk of burnout.

– In case your LED panel isn’t working in any respect then the most definitely motive for that is faulty inner wiring where the wiring just isn’t related to the driver correctly.

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


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

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

– Ask an electrician to verify that the wiring within the lighting system is fitted correctly.

Problems with poor insulation, ventilation and overheating

LED panels have to be properly insulated to make sure 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 (often 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 surplus heat can cause the LED chips within 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 a lot of an issue with LED panels as they’re often designed to slot in enclosed fixtures, nonetheless, it’s always price checking the panels are suitable to be installed into recessed fittings.

– Poor quality or faulty 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 problems with drivers and voltage conversion above).


– Only purchase ceiling led panel light panels with a correctly fitted aluminium heat sink. Make sure the panel is designed to be installed into a recessed fitting.

Problems with low high quality LEDs

LED panels are dearer than conventional fluorescent tubes and because of this consumers might select low cost, low quality LEDs and anticipate the same efficiency from them because the leading brands. Low quality LED panels typically characteristic inferior components that aren’t examined correctly.

LED panels function a lot of elements; if any of these elements are low quality or faulty it could possibly affect the overall efficiency of the LED panels.


– Frame-often manufactured from aluminium, the frame contains the sunshine inside the panel. – If the body is simply too gentle or is product of a cloth aside from aluminium (cheap LED panels typically function a plastic body), then this might create excess heat and enhance the danger of burn out from overheating.

– Low high quality chips may cause quite a lot of issues together with the panel turning into dim or the colour high 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 appropriately then this may affect on the quantity of light and the angle of the light reaching the diffuser.

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

– Issues with the reflector plate may cause glare.

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

– The higher the again cowl matches the body, the better the heat dissipation which implies the panel is prone to final longer.

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

Solution: How to pick a quality LED panel

– Choose a panel that’s a minimum of £15-30 or £30 – 50 for increased end. In the case of LED panels price does point out quality. Panels under £12 will go yellow, ripple or warp much faster.

– Avoid panels that solely have a two 12 months warranty. They only have a two year warranty because they don’t seem to be constructed to last! 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 panel that’s finished with powder coating versus paint.

– Look for a effectively-constructed frame.

– Choose a trusted model. There are many them on the market, here are just some of our favourites: – Britesource

– Philips

– Osram

– Toshiba

Methyl styrene is the best materials to decide on for the sunshine guide plate (LGP)

There are a few minor indications of high quality equivalent to a panel that’s completed with powder coating moderately than paint and a well-constructed frame however, the actual marker of high quality comes down to the material used to make the light guide plate.

There are three supplies commonly used to make an LGP:


– Polystyrene (PS)

– MS

We suggest choosing an LGP made of MS.

PMMA has one of the best light transmission and sturdiness however can also be probably the most expensive – it is a high-high quality product, but not the most inexpensive.

PS affords good transmission, LED panel light but it tends to show yellow over time as a consequence of wear and tear and the effects of heat. It is a well known problem in the industry and is commonly why these panels have a guaranty of solely 2 years. Over time they may also ripple of change into warped because they aren’t robust sufficient to handle normal heat exposure. It is the cheapest choice of the three, however we might consider it a low-high quality choice.

MS is a mix of PMMA and PS. It supplies superb mild transmission and is also durable, however at a lower worth, is essentially the most cost-efficient solution.

Problems with LED panels failing early


LEDs are incredibly fashionable as a result of they’re known to last for much longer than customary halogen or LED panel lighting for sale fluorescent bulbs. Some LEDs can last over 15,000 hours, that means they should last an extremely very long time. This form of longevity makes LED value price-efficient and environmentally pleasant.
