Common Problems With LED Panels And The Way To Fix Them

Many of the problems that have an effect on the performance of LED panels are universal to all LEDs, such as flickering, glowing, burnout and buzzing.

Quick LED panel problem detection

In case your LED panel is failing and you're not sure of the fault, there is a fast and diagnosis you can do. Try switching on the LED panel and test the table below.

Detecting the problem and the possible cause is simply half the battle. Within the sections below, you'll be capable of finding the options to these problems.

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 therefore stop power surges. LED drivers are small units 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 accurately can be affected by heat over time. However utilizing low cost, low quality drivers or the wrong driver will mean it's at greater danger of overheating sooner.


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


- Voltage from the mains power supply is (240v), a driver converts this to 12v or 24v to run the panel correctly. If the driver isn’t working accurately then it doesn’t convert this present and retains the voltage at a relentless level. This implies the bulb will flicker and the system won’t react to overloads which means the panels are at an increased threat of burnout.
- In case your LED panel isn’t working in any respect then the most probably purpose for this is faulty internal wiring where the wiring shouldn't be connected to the driver correctly.
- Although not technically a fault with the wiring, fitting dimmable LED panels with an incompatible dimmer swap will trigger flickering.

Solutions

- Ensure your LED panels are compatible with the circuits, energy supply and gentle switches they are working off.
- Invest in again-lit or central-lit panels (where the LED chips are mounted onto the panel, reasonably than the sting of the panel), as these panels feature built-in drivers which might help to cut back the issues with drivers outlined above.
- Ask an electrician to test that the wiring within 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 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 high quality, poorly fitted or not fitted in any respect then the surplus 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 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 often designed to slot 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 could cause LED panels to overheat and burnout.
- If the LED panel driver is defective then this may name the panel to overheat (see problems with drivers and voltage conversion above).

Solution

- Only buy LED panels with a appropriately fitted aluminium heat sink. Make sure the panel is designed to be put in into a recessed fitting.

Problems with low quality LEDs

LED panels are costlier than conventional fluorescent tubes and for this reason shoppers could select low-cost, low quality LEDs and count on the same efficiency from them as the leading brands. Low high quality LED panels typically feature inferior elements that aren’t examined properly.


LED panels feature a variety of elements; if any of those elements are low quality or defective it could affect the general performance of the LED panels.

Problems

- Frame-usually manufactured from aluminium, the body accommodates the sunshine throughout the panel. - If the body is simply too mild or is made of a material other than aluminium (low cost LED panels typically function a plastic frame), then this might create excess heat and improve the chance of burn out from overheating.


- Low high quality chips could cause plenty of problems including the panel turning into dim or the color high quality being compromised.
- If low high quality LED chips are utilized in a panel this may 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 gentle and the angle of the light reaching the diffuser.


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

- Issues with the reflector plate may cause glare.

- A poor quality heat sink will mean not sufficient heat is dissipated from the LED chips which could cause the chips to burnout.
- Cheap plastic heat sinks don’t work as successfully as metal heat sinks and might cut back the life expectancy of the LEDs within the panel.


- The higher the again cover suits the body, the higher the heat dissipation which means the panel is likely to last longer.


It’s very troublesome to identify whether an LED panel is high or low quality till it's installed. You won’t necessarily know you might have a low quality LED till it burns out quickly or produces poor high quality mild for example.

Solution: How to pick a high quality LED panel

- Choose a panel that's at the least £15-30 or £30 - 50 for increased finish. In terms of LED panels value does indicate high quality. Panels under £12 will go yellow, ripple or warp much faster.
- Avoid panels that solely have a two year warranty. They solely have a two yr guarantee because they don't seem to be constructed to final! Good high quality panels will last 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 is completed with powder coating versus paint.
- Search for a effectively-constructed body.
- Choose a trusted brand. There are plenty of them out there, listed here are only a few of our favourites: - Britesource
- Philips
- Osram
- Toshiba

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

There are a couple of minor indications of quality similar to a panel that's finished with powder coating quite than paint and a nicely-constructed body nevertheless, the real marker of quality comes all the way down to the material used to make the light guide plate.

There are three supplies generally used to make an LGP:

- PMMA
- Polystyrene (PS)
- MS

We suggest choosing an LGP made from MS.

PMMA has the most effective gentle 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 turn yellow over time on account of put on and tear and the results of heat. It is a well-known situation within the trade and is often why these panels have a guaranty of only 2 years. Over time they can even ripple of become warped as a result of they aren’t robust enough to handle normal heat exposure. It's the most cost effective choice of the three, however we would consider it a low-quality choice.


MS is a mix of PMMA and PS. It supplies superb gentle transmission and can be durable, however at a lower price, is essentially the most value-efficient solution.

Overview


LEDs are extremely in style as a result of they are identified to final for much longer than customary halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, that means they need to final an extremely long time. This form of longevity makes LED price cost-efficient and environmentally friendly.
