LED RADIATION

LED based light sources do not emit any UV radiation (unless specifically designed for that particular purpose). Therefore, they are not harmful to people with a specific sensitivity for certain UV radiation and can bring relief to certain groups of patients. In this respect, LED based light sources provide advantages over traditional incandescent, halogen and Compact Fluorescent lamps.

In contrast to most other light sources, e.g. halogen and incandescent lamps, LEDs hardly emit IR light (unless specifically designed to emit a certain type of IR). For available types of indoor light sources the IR radiation is not powerful enough to pose any risks to human.

LED BULB SAFETY

Optical safety refers to the prevention1 of hazards through optical radiation (electromagnetic radiation of wavelengths ranging from 100 nm to 1 mm). Effects on the eyes as well as the skin are considered, also for those people with a higher sensitivity. In response to the concerns raised by the last group, Annex 1 provides more detailed considerations for this specific group. Commonly discussed hazards affecting the eye are blue light hazard (BLH) and age‐related macular degeneration (AMD) which can be induced or aggravated by high intensity blue light.  When looking directly into a bright light source, a photochemical damage to the retina (blue light hazard) can occur, depending on the intensity involved and the time of exposure. People are familiar with this phenomenon from looking at the sun. To prevent retinal damages, appropriate spectacles must be worn when observing a solar eclipse, for instance. On a bright and sunny day, however, a natural reflex occurs (eyelid close reflex, aversion) that protects the eye from being harmed. Furthermore, UV
