How To Repair Strobing Led Corn Bulb
Many of the bug that affect the performance of LED panels are universal to all LEDs, such as flickering, glowing, burnout and buzzing. For detailed data on how to gainsay these typical bug with LEDs, bank check out our article How to Stop Your LEDs from Flickering, Buzzing, Glowing and Called-for Out.
There are some problems that specifically affect LED panels. The content on this page takes a closer look at these:
- Quick LED panel problem detection
- Bug with drivers and voltage conversion
- Problems with poor insulation, ventilation and overheating
- Issues with low quality LEDs
- How to select a quality LED panel

Quick LED panel problem detection
If your LED panel is failing and you are not certain of the fault, there is a quick and diagnosis yous tin can do. Endeavour switching on the LED panel and check the table below.
Mutual LED problems and their likely causes
Problem | Probable cause |
---|---|
The LED panel does non illuminate at all | Driver failure |
The LED console flashes | Commuter failure |
If only some of the LEDs in the panel are lit | LED failure |
Detecting the problem and the likely cause is only half the battle. In the sections beneath, you will be able to notice the solutions to these problems.
Problems with drivers and voltage conversion
Overview
An LED driver regulates the amount of ability that flows through a lighting system. Drivers convert the Ac power from the mains supply to the DC power required to run LED panels and therefore prevent power surges. LED drivers are pocket-sized units that are wired to the LED panel. They play a like part to ballasts in fluorescent lights.
Drivers are vulnerable to overheating. Even drivers that work correctly will be affected past heat over time. Nevertheless using cheap, low quality drivers or the wrong commuter volition hateful information technology is at greater risk of overheating sooner.
This is because the current flowing through the organisation isn't kept at a abiding level, and so the excess heat generated impacts the driver'south performance.
Bug
- 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 correctly then information technology doesn't catechumen this current and keeps the voltage at a constant level. This means the bulb will flicker and the arrangement won't react to overloads which means the panels are at an increased risk of burnout.
- If your LED panel isn't working at all then the nearly probable reason for this is faulty internal wiring where the wiring is not connected to the driver correctly.
- Although non technically a fault with the wiring, plumbing fixtures dimmable LED panels with an incompatible dimmer switch will crusade flickering.
Solutions
- Ensure your LED panels are compatible with the circuits, ability supply and lite switches they are running off.
- Invest in back-lit or fundamental-lit panels (where the LED chips are mounted onto the console, rather than the edge of the panel), every bit these panels feature congenital-in drivers which tin help to reduce the problems with drivers outlined above.
- Ask an electrician to check that the wiring in the lighting system is fitted correctly.
Problems with poor insulation, ventilation and overheating
Overview
LED panels must exist properly insulated to ensure the heat they produce is dissipated correcting and then they don't overheat. Quality LED panels are fitted with a estrus sink made from a conductive metallic (usually aluminium) which transfers excess heat away from the console. If this heat sink is low quality, poorly fitted or not fitted at all then the backlog heat tin can cause the LED chips in the panel to exhaustion.
Not all LEDs are suitable to be fitted into enclosed fixtures. Plumbing fixtures an unsuitable LED into an enclosed fitting tin can cause it to overheat as the bulb won't take the appropriate heat sink. This isn't every bit much of an issue with LED panels as they are usually designed to fit in enclosed fixtures, however, it's always worth checking the panels are suitable to be installed into recessed fittings.
Problems
- Poor quality or faulty heat sinks can cause LED panels to overheat and burnout.
- If the LED panel driver is faulty and so this can also call the panel to overheat (come across problems with drivers and voltage conversion above).
Solution
- Simply buy LED panels with a correctly fitted aluminium heat sink. Ensure the console is designed to be installed into a recessed fitting.
Problems with low quality LEDs
Overview
LED panels are more than expensive than traditional fluorescent tubes and for this reason consumers may choose cheap, depression quality LEDs and wait the aforementioned performance from them every bit the leading brands. Depression quality LED panels ofttimes characteristic inferior components that aren't tested properly.
LED panels feature a number of components; if whatever of these components are low quality or faulty it can bear upon the overall performance of the LED panels.
Bug
- Frame—commonly fabricated of aluminium, the frame contains the light within the panel.
- If the frame is too light or is made of a material other than aluminium (inexpensive LED panels oft feature a plastic frame), and then this could create excess heat and increase the chance of burn out from overheating.
- LED fries— these chips are mounted to a circuit board and are what produce the low-cal. Depending on the type of panel, they are mounted to the dorsum or sides of the panel.
- Low quality chips tin cause a number of bug including the panel becoming dim or the colour quality being compromised.
- If low quality LED chips are used in a panel this can produce a 'blue' hue which can brand a room await cold.
- Light guide plate—this points the light coming from the LEDs towards the diffuser.
- If it'due south not fitted correctly then this tin impact on the amount of lite and the angle of the light reaching the diffuser.
- Diffuser—this ensures the light coming from the LEDs is evenly distributed and helps to reduce glare.
- A low quality diffuser, made from acrylic or PMMA rather than polycarbonate, won't distribute light as evenly.
- Overtime, plastic diffusers tin can discolour at the edges and turn yellow, reducing the quality of lite produced by the LED panel.
- Reflector plate—this reflects calorie-free dorsum into the low-cal guide plate.
- Issues with the reflector plate can cause glare.
- Heat sink— this helps to forbid LED panels from overheating as a conductive metal heat sink takes away excess heat to go along the panel cool.
- A poor quality heat sink will mean not enough heat is dissipated from the LED chips which tin cause the chips to exhaustion.
- Cheap plastic oestrus sinks don't work as effectively as metal heat sinks and tin can reduce the life expectancy of the LEDs in the panel.
- Back encompass—an aluminium plate that protects the components.
- The better the dorsum embrace fits the frame, the better the oestrus dissipation which means the panel is likely to final longer.
It's very hard to identify whether an LED panel is loftier or low quality until it is installed. You won't necessarily know y'all have a low quality LED until it burns out speedily or produces poor quality lite for case.
Solution: How to select a quality LED console
- Choose a panel that is at least £15-30 or £30 – fifty for higher end. When it comes to LED panels cost does point quality. Panels under £12 volition go yellow, ripple or warp much quicker.
- Avoid panels that simply have a 2 year warranty. They merely have a two year warranty because they are not built to final! Good quality panels will last longer than this.
- Cull a console that has a light guide plate made out of acrylic (PMMA) or methyl styrene (MS).
- Choose a panel that is finished with powder coating every bit opposed to paint.
- Wait for a well-constructed frame.
- Choose a trusted brand. In that location are plenty of them out there, here are just a few of our favourites:
- Britesource
- Philips
- Osram
- Toshiba
- Speak to the company selling the LEDs and ask them about the quality of the LED panels they sell. A trusted company will exist able to offer advice. If the company you're considering ownership from are hard to arrive touch with and then reconsider buying from them.
- Look at reviews
- Replace poor quality panels with meliorate quality panels. Sticking with your existing low quality panels will mean existing problems volition go on. High quality LED panels where the drivers, eyes and LEDs all work at an optimum level could reduce running costs by 25% compared with lower toll panels.
Methyl styrene is the best material to cull for the calorie-free guide plate (LGP)
In that location are a couple of small-scale indications of quality such equally a panel that is finished with powder coating rather than pigment and a well-constructed frame yet, the real marker of quality comes down to the textile used to make the light guide plate.
There are iii materials ordinarily used to make an LGP:
- PMMA
- Polystyrene (PS)
- MS
We recommend choosing an LGP made of MS.
PMMA has the best light transmission and durability merely is also the most expensive – it is a high-quality product, only not the most affordable.
PS offers good manual, but it tends to plow yellowish over time due to clothing and tear and the effects of estrus. It is a well-known consequence in the industry and is frequently why these panels have a warranty of only 2 years. Over time they can also ripple of become warped because they aren't robust enough to handle normal heat exposure. Information technology is the cheapest pick of the iii, but we would consider it a low-quality choice.
MS is a combination of PMMA and PS. It provides very good light transmission and is likewise durable, merely at a lower price, is the most cost-effective solution.
Problems with LED panels declining early
Overview
LEDs are incredibly popular because they are known to last much longer than standard halogen or fluorescent bulbs. Some LEDs can concluding over fifteen,000 hours, meaning they should terminal an incredibly long fourth dimension. This sort of longevity makes LED price toll-effective and environmentally friendly.
When your LED panel fails early, it means at that place is a trouble.
Problem
- LED console does not last the expected corporeality of time
Solution: fix high temperatures
- LEDs run at a much lower temperature than element of group vii bulbs
- LEDs exercise not deal with loftier temperatures very well
- Ensure that your LEDs have enough ventilation space (see above for advice)
- Ensure that your panels are not nearly any sources of intense heat
- Effort to avoid using a mixture of fluorescent and LED panels in a single room
