Some manufacturers cut costs by using plastic for their back plates.
The back plate helps to maintain the rigidity and durability of the panel.
The final part of the LED panel construction is the back plate.Ī well-fitted metal back plate acts as an additional heatsink to ensure the long and efficient life of the LED chips. This will result in ‘wave light patterns’ across the LED panel. Improper fixing of this reflective paper or just simply having poor quality paper results in uneven distribution of the light from the LGP onto the diffusion plate. The reflective paper should be of high-quality, highly reflectivity paper that will not degrade within the design life of the panel and must be held in close contact with the back of the LGP. You would think this ‘simple’ component of the LED panel system would be difficult to get wrong! It is, but many manufacturers will even try to save a few pence here. You will be relieved to know that our LED panel store uses only high quality Japanese LGP’s which do not suffer from this problem. We have been made aware of a number of incidents where LED panels have been supplied in the UK and have started to show signs of the LGP yellowing in under 12 months! The LGP is an area that allows manufacturers and suppliers to cut corners because it is an area that unless you dismantle the LED panel you will never actually get to inspect.Ĭheaply produced LGP’s will not only fail to distribute light evenly across the front of the panel, but in time they may also exhibit another major problem – a ‘yellowy tinge’ developing unevenly across the LED Panel. This is what distributes the light emitted from the LED chips across then down and out of the LED panel. The Light Guide Plate (LGP) is a key component of the LED panel.
To minimise the risk to our customers in the event of a building fire, the diffusers in our panels are tested by an Independent UK laboratory to BS 2782-0:2004 Annex B (Method 508A) to ensure that they reach Tp(b) as a minimum requirement. This diffusion plate is usually made from polystyrene, which is flammable. The diffusion plate is designed to ensure that the light coming out of the LED panel is distributed as evenly as possible and to minimise glare. A well-constructed frame will ensure that the LED chips are cooled properly in order to prolong their life and minimise lumen depreciation (LM80/LM79). The frame also provides the vital function of cooling the LED chips – it acts as a heatsink. The frame forms part of the structural backbone of the whole LED system, including the LED chips, and must not be too lightweight or poorly constructed that it twists and bends easily. Exploded View of a Typical LED Panel Aluminium Frame So if you’re looking for commercial LED lighting and think LED panels might be right for you, we have decided to explain each component that is used in the construction of an LED panel light to help you know what to look out for. This will also help you understand why you will see so many different price variations.

We have decided that you, the customer, should be given a full explanation about how LED light panels are constructed and what effect that construction has on the performance and reliability of these products. Most suppliers don’t even know what brand of LED chip is being used within the panels they are supplying! Many LED suppliers make baseless and sometimes false claims about their LED panels. The answer to the above question is a definite NO! LED panels consist of many components, and it is the quality of these components that directly affects the performance, lifespan, and of course the price of the LED light panel.
