Detecting the issue and the possible trigger is simply half the battle. In the sections below, you may be capable of finding the solutions to these issues.

Problems with drivers and voltage conversion

An LED driver regulates the quantity of energy that flows via a lighting system. Drivers convert the AC energy from the mains provide to the DC energy required to run LED panels and due to this fact forestall power surges. LED drivers are small models that are wired to the LED panel. They play the same role to ballasts in fluorescent lights.

Drivers are weak to overheating. Even drivers that work correctly will likely be affected by heat over time. However using low cost, low high quality drivers or the flawed driver will mean it is at greater threat of overheating sooner.

This is because the current flowing via the system isn’t stored at a relentless degree, so the excess heat generated impacts the driver’s efficiency.

– 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 keeps the voltage at a constant stage. This means the bulb will flicker and the system won’t react to overloads which means the panels are at an increased danger of burnout.

– In case your LED panel isn’t working in any respect then the probably purpose for this is faulty inside wiring where the wiring is not related to the driver correctly.

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

Solutions

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

– Put money into again-lit or central-lit panels (the place the LED chips are mounted onto the panel, relatively than the edge of the panel), as these panels function constructed-in drivers which can assist to cut back the issues with drivers outlined above.

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

Problems with poor insulation, ventilation and overheating

LED panels must 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 metallic (often aluminium) which transfers excess heat away from the panel. If this heat sink is low quality, poorly fitted or not fitted at all then the excess heat could 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 could cause it to overheat as the bulb won’t have the appropriate heat sink. This isn’t as a lot of a problem with LED panels as they’re normally designed to fit in enclosed fixtures, however, it’s always price checking the panels are appropriate to be installed into recessed fittings.

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

Solution

– Only purchase LED panels with a correctly 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 conventional fluorescent tubes and for that reason shoppers might select cheap, low high quality LEDs and count on the identical performance from them because the leading manufacturers. Low high quality LED panels usually feature inferior components that aren’t examined properly.

LED panels function plenty of elements; if any of those elements are low high quality or faulty it could possibly have an effect on the overall efficiency of the LED panels.

Problems

– Frame-often product of aluminium, the body contains the light inside the panel. – If the frame is simply too mild or is manufactured from a cloth apart from aluminium (low-cost ceiling led panel light panels typically function a plastic body), then this might create excess heat and enhance the danger of burn out from overheating.

– Low quality chips can cause numerous problems together with the panel changing into dim or the color quality being compromised.- If low quality LED chips are utilized in a panel this will produce a ‘blue’ hue which can make a room look cold.

– If it’s not fitted correctly then this will impact on the amount of gentle and the angle of the light reaching the diffuser.

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

– Issues with the reflector plate could cause glare.

– A poor quality heat sink will imply not sufficient heat is dissipated from the LED chips which can cause the chips to burnout.- Cheap plastic heat sinks don’t work as successfully as steel heat sinks and can reduce the life expectancy of the LEDs within the panel.

– The higher the back cover matches the body, the higher the heat dissipation which suggests the panel is likely to last longer.

It’s very difficult to establish whether or not an LED panel is high or low quality till it is put in. You won’t essentially know you may have a low quality LED till it burns out quickly or produces poor quality gentle for instance.

Solution: How to select a high quality LED panel

– Choose a panel that’s not less than £15-30 or £30 – 50 for larger end. In relation to LED panels price does indicate high quality. Panels underneath £12 will go yellow, ripple or warp a lot quicker.

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

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

– Choose a panel that’s finished with powder coating as opposed to paint.

– Search for a nicely-constructed frame.

– Choose a trusted brand. There are many them on the market, here are only a few of our favourites: – Britesource

– Philips

– Osram

– Toshiba

Methyl styrene is one of the best material to decide on for the light guide plate (LGP)

There are a few minor indications of quality equivalent to a panel that’s finished with powder coating slightly than paint and a properly-constructed frame nevertheless, the true marker of quality comes right down to the fabric used to make the light guide plate.

There are three materials generally used to make an LGP:

– PMMA

– Polystyrene (PS)

– MS

We recommend selecting an LGP made of MS.

PMMA has the perfect mild transmission and sturdiness but can also be probably the most costly – it is a excessive-quality product, however not probably the most affordable.

PS presents good transmission, but it surely tends to show yellow over time as a consequence of put on and tear and the results of heat. It is a well known challenge in the trade and is commonly why these panels have a warranty of only 2 years. Over time they can even ripple of grow to be warped as a result of they aren’t sturdy sufficient to handle normal heat publicity. It’s the most cost effective option of the three, however we might consider it a low-high quality alternative.

MS is a mixture of PMMA and PS. It provides excellent light transmission and is also durable, however at a lower price, is essentially the most value-efficient solution.

Overview

LEDs are incredibly widespread because they are known to final for much longer than commonplace halogen or fluorescent bulbs. Some LEDs can final over 15,000 hours, which means they should last an incredibly long time. This type of longevity makes LED cost price-efficient and environmentally pleasant.
