Afrolux Luminance Product Life Cycle

Afrolux Luminance Product Life Cycle

The product life cycle comprises the entire life of a product, from raw material extraction and acquisition, through material production and manufacturing, to use and end of life treatment including recycling and final disposal. In other words, a product life cycle encompasses the consecutive and interlinked stages of a product from cradle to grave, or rather from cradle to cradle with regard to recycling.

Life cycle analysis of an AFROLUX light-emitting diode lamp

Average lifetime  40 000 h
Lumen  622
Watt  8

A light-emitting diode (LED) is a semiconductor diode that emits narrow-spectrum light. Depending on the used material, LEDs are able to emit light in different colors. To produce white light, the light of blue LED is passed through yellow phosphor, whose composition determines the final color temperature.

To make LED usable in household fixtures, several LEDs are combined with an electronic control gear in a bulb-shaped form. By selecting appropriate white LED, it is possible to offer LED systems with the same light color as fluorescent lamps. Due to their remarkably low energy consumption, their extremely long life and their low maintenance cost, LED lamps are the most efficient household lamps.

CED and Global Warming Potential of the use and manufacturing phase:
 Depending on the electricity mix, an LED lamp may also be responsible for mercury emissions during use. This is due to the comparatively high ratio of coal power plants in some electricity mixes, which emit mercury by burning lignite or hard coal to produce electricity. Nevertheless, in comparison to incandescent and halogen lamps, LED lamps are associated with far less mercury emissions during use. This is due to their high energy efficiency which is responsible for saving up to 80 percent of electricity and thus for reducing mercury emissions resulting from electricity production by coal power plants. Thus, LED lamps offer the lowest possible mercury impact on the environment.

Applicability of this life cycle analysis:
Similar to compact fluorescent lamps, different types of LED lamps have different impacts during production. Due to the dynamic development of LED lamps, a generalization for the relationship between light output and impact of production is very difficult. However, the use phase continues to be the most influential life cycle stage with the greatest impact, so it is much more important to calculate the effect of this phase. For this purpose, it is merely necessary to recalculate the Cumulated Energy Demand based on the wattage of the lamps, according to the three steps illustrated in the table above.
