How To Repair Led Corn Bulb Electronic Driver

Many of the issues that affect the performance of LED panels are universal to all LEDs, such every bit flickering, glowing, burnout and buzzing. For detailed information on how to gainsay these typical problems with LEDs, check out our article How to Stop Your LEDs from Flickering, Buzzing, Glowing and Called-for Out.

There are some bug that specifically affect LED panels. The content on this page takes a closer look at these:

• Quick LED console problem detection

Quick LED panel problem detection

If your LED panel is failing and you lot are not sure of the fault, there is a quick and diagnosis you can practice. Effort switching on the LED panel and check the table below.

Common LED issues and their likely causes

Problem	Likely crusade
The LED panel does not illuminate at all	Commuter failure
The LED console flashes	Driver failure
If only some of the LEDs in the panel are lit	LED failure

Detecting the problem and the likely cause is but half the battle. In the sections beneath, you will be able to find the solutions to these problems.

Problems with drivers and voltage conversion

Overview

An LED driver regulates the amount of power that flows through a lighting arrangement. Drivers convert the Air-conditioning power from the mains supply to the DC power required to run LED panels and therefore prevent ability surges. LED drivers are small units that are wired to the LED console. They play a similar role to ballasts in fluorescent lights.

Drivers are vulnerable to overheating. Fifty-fifty drivers that work correctly will be afflicted by heat over time. Nevertheless using cheap, low quality drivers or the incorrect driver volition hateful it is at greater risk of overheating sooner.

This is because the current flowing through the arrangement isn't kept at a constant level, so the excess oestrus generated impacts the driver's performance.

Problems

• Voltage from the mains power supply is (240v), a driver converts this to 12v or 24v to run the console correctly. If the driver isn't working correctly and so it doesn't convert this current and keeps the voltage at a constant level. This means the seedling will flicker and the system won't react to overloads which ways the panels are at an increased gamble of burnout.
• If your LED panel isn't working at all then the almost likely reason for this is faulty internal wiring where the wiring is not connected to the commuter correctly.
• Although not technically a fault with the wiring, fitting dimmable LED panels with an incompatible dimmer switch will crusade flickering.

Solutions

• Ensure your LED panels are compatible with the circuits, power supply and calorie-free switches they are running off.
• Invest in dorsum-lit or central-lit panels (where the LED fries are mounted onto the panel, rather than the border of the panel), as these panels feature built-in drivers which tin assist to reduce the problems with drivers outlined higher up.
• Ask an electrician to bank check that the wiring in the lighting system is fitted correctly.

Problems with poor insulation, ventilation and overheating

Overview

LED panels must be properly insulated to ensure the heat they produce is prodigal 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 quality, poorly fitted or not fitted at all then the excess heat tin can cause the LED chips in the panel to burnout.

Not all LEDs are suitable to be fitted into enclosed fixtures. Fitting an unsuitable LED into an enclosed fitting can cause it to overheat as the bulb won't accept the appropriate rut sink. This isn't as much of an upshot with LED panels as they are usually designed to fit in enclosed fixtures, however, it's always worth checking the panels are suitable to exist installed into recessed fittings.

Problems

• Poor quality or faulty estrus sinks can cause LED panels to overheat and exhaustion.
• If the LED panel driver is faulty and so this can as well phone call the panel to overheat (run into issues with drivers and voltage conversion in a higher place).

Solution

• Only buy LED panels with a correctly fitted aluminium rut sink. Ensure the console is designed to be installed into a recessed fitting.

Bug with depression quality LEDs

Overview

LED panels are more expensive than traditional fluorescent tubes and for this reason consumers may choose inexpensive, low quality LEDs and expect the aforementioned performance from them as the leading brands. Low quality LED panels often feature inferior components that aren't tested properly.

LED panels characteristic a number of components; if any of these components are low quality or faulty it tin can affect the overall operation of the LED panels.

Issues

• Frame—usually made of aluminium, the frame contains the lite within the panel.
  • If the frame is too lite or is made of a material other than aluminium (inexpensive LED panels ofttimes feature a plastic frame), then this could create excess heat and increase the risk of burn out from overheating.
• LED chips— these chips are mounted to a excursion board and are what produce the calorie-free. Depending on the type of panel, they are mounted to the back or sides of the panel.
  • Low quality chips can cause a number of problems including the panel becoming dim or the colour quality beingness compromised.
  • If low quality LED chips are used in a panel this tin can produce a 'blueish' hue which can make a room expect cold.
• Light guide plate—this points the light coming from the LEDs towards the diffuser.
  • If it'south non fitted correctly then this can 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 every bit evenly.
  • Overtime, plastic diffusers can discolour at the edges and turn yellow, reducing the quality of low-cal produced by the LED panel.
• Reflector plate—this reflects light dorsum into the light guide plate.
  • Issues with the reflector plate can cause glare.
• Heat sink— this helps to prevent LED panels from overheating as a conductive metal oestrus sink takes abroad backlog heat to go along the panel cool.
  • A poor quality heat sink will mean not enough heat is dissipated from the LED fries which tin cause the chips to exhaustion.
  • Cheap plastic estrus sinks don't work as effectively as metal rut sinks and can reduce the life expectancy of the LEDs in the panel.
• Back embrace—an aluminium plate that protects the components.
  • The ameliorate the back comprehend fits the frame, the better the heat dissipation which means the panel is likely to last longer.

It'due south very difficult to identify whether an LED panel is loftier or depression quality until it is installed. You won't necessarily know you have a depression quality LED until it burns out quickly or produces poor quality light for example.

Solution: How to select a quality LED panel

• Choose a panel that is at least £fifteen-xxx or £30 – l for college stop. When it comes to LED panels cost does betoken quality. Panels under £12 will go yellow, ripple or warp much quicker.
• Avoid panels that just have a ii year warranty. They merely have a two yr warranty because they are not built to last! Good quality panels volition final longer than this.
• Choose a panel that has a light guide plate fabricated out of acrylic (PMMA) or methyl styrene (MS).
• Choose a panel that is finished with powder coating as opposed to paint.
• Expect for a well-constructed frame.
• Cull a trusted brand. There are plenty of them out in that location, here are only a few of our favourites:
  • Britesource
  • Philips
  • Osram
  • Toshiba
• Speak to the visitor selling the LEDs and enquire them about the quality of the LED panels they sell. A trusted company will be able to offer advice. If the visitor you're considering buying from are hard to go in touch with then reconsider ownership from them.
• Look at reviews
• Replace poor quality panels with better quality panels. Sticking with your existing depression quality panels will hateful existing issues will keep. High quality LED panels where the drivers, optics and LEDs all work at an optimum level could reduce running costs by 25% compared with lower price panels.

Methyl styrene is the all-time material to choose for the calorie-free guide plate (LGP)

There are a couple of minor indications of quality such as a panel that is finished with pulverisation coating rather than paint and a well-constructed frame however, the real marker of quality comes down to the material used to make the light guide plate.

There are three materials commonly used to make an LGP:

• PMMA
• Polystyrene (PS)
• MS

We recommend choosing an LGP fabricated of MS.

PMMA has the best light transmission and durability merely is also the most expensive – it is a high-quality product, but not the most affordable.

PS offers expert manual, but it tends to plough yellow over fourth dimension due to wearable and tear and the effects of heat. It is a well-known outcome in the industry and is often why these panels have a warranty of only two years. Over time they can also ripple of become warped considering they aren't robust enough to handle normal rut exposure. Information technology is the cheapest option of the three, simply we would consider it a low-quality choice.

MS is a combination of PMMA and PS. It provides very good lite transmission and is also durable, merely at a lower price, is the most price-effective solution.

Problems with LED panels failing early

Overview

LEDs are incredibly popular because they are known to concluding much longer than standard halogen or fluorescent bulbs. Some LEDs can last over 15,000 hours, meaning they should last an incredibly long fourth dimension. This sort of longevity makes LED cost cost-effective and environmentally friendly.

When your LED panel fails early on, information technology means there is a problem.

Trouble

• LED console does not last the expected amount of time

Solution: set up high temperatures

• LEDs run at a much lower temperature than halogen bulbs
• LEDs do non deal with high temperatures very well
• Ensure that your LEDs have enough ventilation infinite (encounter higher up for advice)
• Ensure that your panels are non almost any sources of intense heat
• Try to avert using a mixture of fluorescent and LED panels in a single room
