The light emitting diode (LED) belongs to the most efficient white-light source on the market. In terms of energy savings, it is clearly at hand that the LED is far superior compared to standard filament bulbs and halogen bulbs. Meanwhile, developments have already produced LEDs with a light yield of 200 Lumen per Watt (lm/W) and twice the efficiency of comparable luminescent tubes. However, when is it worthwhile to consider a conversion?
According to the "Statistisches Bundesamt" (German Federal Statistical Office), the lighting system of companies incurs approximately 6 % of their total energy consumption. Using LEDs, you can reduce energy costs to 20 %, with resultant savings of approximately 4.8 % on total energy costs. However, the relatively high costs of procurement or conversion are not amortized based solely on energy cost savings. The great potential – under monetary aspects, as well – involved with this relatively young technology is not disclosed until you take a second look at it.
Conservation of resources, extended useful life, environmental compatibility and user comfort are terms that can be mentioned in the same breath without ifs and buts when speaking of modern LED technology. Initial constructive issues, e.g. a certain glare effect of LED spotlight source, dimming capabilities, complex temperature management or necessary heatsink issues, as well as restraints with regard to the light color have been solved technically to the greatest extent. What remains is the comparably high price.
Regardless of the costs of investment, the conversion from standard to LED lighting technology is beneficial in more areas than it might at first sight appear. Even if you only take a brief glance at the energy balance of application scenarios such as underground car parks, extensive hallways, generous shop window or outdoor lighting systems, you can see that these return amortization periods between two and four years. However, when taken as complementary measure there are many applications that return financial benefits which are disclosed only indirectly or difficult to calculate.
While the transfer of the factor extended useful life of an LED from between 20,000 and 50,000 operating hours to the low maintenance factor is quite easy, it becomes more complex when we look at the topic "proper lighting in office rooms". The flexibility that comes with LED technology allows you to set your lighting control system to increase the proportion of blue in the visible light, which has a positive impact on the concentration capability and personal motivation of the employees and increases productivity. This dynamic lighting design is also utilized by the trading sector. Many studies have proven that a significant positive effect on sales figures can be gained by the correct adaptation of light color to the merchandise that is to be displayed, e.g. meat products, fruit and vegetable products, or jewelry.
Another factor is that the prices for the light source will drop within the next years due to its entry into the volume market, e.g. end users, municipalities and enterprises now systematically convert to the new technology. The new possibilities in light design will open opportunities to define entirely new products and services and open new markets. Clarification, information and professional advice will be increasingly important in order to counter reservations and uncertainty. This is precisely where Bürklin Elektronik defines its role as partner for enterprises of the branch. In addition to our high-quality LED modules and corresponding accessories, we invite you to take advantage of our services with regard to this promising topic.
