What is an LED?
A light-emitting diode, or LED, is a compound semiconductor device that converts electricity into light. One of more LEDs combined with a driver, housing and other components create a complete LED system.

What makes a robust LED system?
There are four main design factors that determine LED system performance.
- OPTICAL DESIGN
LEDs are a directional light source, meaning they emit light in a single direction. Through carefully designed reflectors and lenses, light is directed only where it is needed, minimizing wasted light and energy.
- MECHANICAL DESIGN
Because LEDs last for years, the materials and construction of an LED system are critical for performance. Careful mechanical engineering protects the LED system from corrosion and humidity to ensure long service life.
- THERMAL DESIGN
Excess heat causes reduced life and color shift in LEDs. With effective thermal management, heat is dissipated, thereby improving LED performance.
- ELECTRICAL DESIGN
Electrical design determines the LED lifespan, light output and color control of the LED system. Precise engineering ensures the right amount of electricity is delivered to the LED chip, enabling consistent, long-lasting LED system performance.
What are the benefits of LEDs?
LEDs offer a number of advantages over conventional light sources. LEDs...
||...contain no mercury, lead, or glass
...offer significant energy savings, up to 90% compared to incandescent in traffic signals
...last for up to 50,000 hours
|...are highly resistant to shock and vibration
...have excellent cold weather performance
...have a quick turn-on time
How can LEDs impact us?
Reducing greenhouse gas emissions with 20% (or even with 30%, if the conditions are right) compared to 1990; gathering 20% more energy from renewables; and increase energy-efficiency in the EU with 20%. These are the main goals of the European Union's Europe 2020 program, regarding the topic of climate change and energy sustainability.
Ecomagination is GE's commitment to build innovative soulitons for today's environmental challenges while driving economic growth.
By switching to GE's LED products is also one of GE Lighting's possible solutions regarding this matter. These applications not only reduce your carbon emission significantly, but also help you to spare energy and material: LED lighting elements use 70% less energy than a „normal” lightbulb.
