We show you the differences in the 5 most popular LED technologies.
LED technology (Light Emitting Diodes) is getting more and more important since the ban of the incandescent light bulb. An LED is a light-emitting semiconductor device (also called diode). Electric current flows through the diode and emits light. This can be done through infrared radiation or ultraviolet radiation which depends on the semiconductor material that is being used and the added atoms from the production of corresponding wavelengths.
LED technology is evolving. CREE already showed LED chips generating up to to 400lm / watts at a minimum pack size! What should be kept in mind: Lumen values are not everything if one wants to reasonably look at the topic LED. Of course light angle, color rendering index, light color and light intensity also play key roles.
