Last week we explored the exciting invention of the electric light bulb, but nowadays LED lights are the real stars of the lighting industry. Yes, you heard right. LEDs (short for light emitting diodes) are the future. Why you ask? Find out right here!

How LEDs work

With an edge length of approximately one millimeter, LEDs are among the smallest light sources on the market and emit an almost point-like light. Light-emitting diodes have quite a simple structure. Two wires, called cathode and anode, lead into a plastic housing containing the actual LED chip with special semiconductor connections. These ensure that the incoming current can only flow in one direction through a solid. As soon as the current flows forwards through the housing, the diode starts to glow. In other words, light is “emitted.” In lighting technology, this is also referred to as “electroluminescence.”1

The pros of LEDs

One of the most decisive advantages of LED bulbs is a significant reduction in electricity consumption, which counteracts the high acquisition costs quickly and saves costs in the long term. Although the luminous flux can gradually decrease, light-emitting diodes rarely fail suddenly. This brings us to another pro of LEDs: a lifespan of up to 50,000 hours. Several other important points to consider are that LED lights do not emit UV radiation, hardly emit any heat and reach full brightness immediately after being switched on.

Summary of LED advantages2

  • Lowers power consumption
  • Longer lifespan: up to 50.000 hours
  • Targeted lighting
  • No UV or infrared rays
  • Low heat emission and heat load on the luminaire
  • Full brightness after switching on
  • Low total cost3

3We are convinced that LEDs are the lighting choice of the future. For this reason, we use the LEDs manufactured by the Japanese company, Nichia, for all of our products. The Deutsche Lichtmiete AG, the parent company of HOLY TRINITY®, has been collaborating successfully with Nichia for many years. In that vein, we’ve also got an innovative rental concept for our luminaires at HOLY TRINITY®. If you’re interested in learning more, please contact us by phone at +49 351 404 555 10 via e-mail at
