Longevity for any amount of time can be actually custom-tailored, however, in the scope of brevity and clarity, the examples used take into account that the LED lighting source can last for approximatively 10 years, while the driver can last for approximatively 5 years. As such, for every extra decade, beyond the 20 years of longevity in the example presented above, the LED lighting system will equipped with 1 (one) additional spare LED lighting source, and 2 (two) additional drivers. This way, by extrapolation, a LED lighting system with a desired longevity approximate of 30 years will consist of 3 (three) LED lighting source and 6 (driver; a desired longevity approximate of 40 years will imply the use of 4 (four) LED lighting source and 8 (eight) drivers; a desired longevity approximate of 50 years will imply the use of 5 (five) LED lighting sources and 10 (ten) drivers; and so on, adding one LED lighting source and two drivers for each additional decade of desired longevity.
Additionally, the number of spare LED lighting sources and driver can vary for each of the examples above. As such, a LED lighting system with a shelf-life of 10 years can be equipped with more than one LED lighting source, so that it has one, two, or more spare LED lighting sources, and more than two drivers, so that it has two, three, or more spare drivers.
The ability of the LED lighting system or apparatus to self-repair stems from the activity of the controller, or microcontroller MCC, and the role it plays in ensuring that the said device is functional.
