White light-emitting diodes (LEDs) pose potential risks to human eye health due to their unique spectral and energetic properties. Some commercial white LEDs were classified into risk group 1 or 2, necessitating safety recommendations.
Area of Science:
- Ophthalmology
- Photobiology
- Public Health
Background:
- Light-emitting diodes (LEDs) are increasingly used in domestic lighting due to low energy consumption.
- The EU is phasing out incandescent bulbs, making LEDs the dominant light source.
- Concerns exist regarding the safety of white LEDs for human health, especially eye health, due to their specific spectral and energetic characteristics.
Purpose of the Study:
- To conduct a health risk assessment of white LEDs.
- To evaluate the potential risks of white LEDs to human health, particularly the eye.
- To provide recommendations to avoid potential retinal hazards from white LEDs.
Main Methods:
- A multidisciplinary task group was formed, including physicists, lighting specialists, retinal biologists, and ophthalmologists.
- Evaluation of group risks for various white LEDs commercialized in the French market.
- Analysis of pre-clinical knowledge and epidemiological studies on LED light exposure.
Main Results:
- Some commercial white LEDs were classified into risk group 1 or 2 according to established standards.
- The spectral and energetic characteristics of white LEDs warrant attention for potential eye safety concerns.
- The study provides a comprehensive analysis of potential risks associated with white LED usage.
Conclusions:
- White LEDs, while energy-efficient, may present retinal hazards.
- Regulatory classification of some white LEDs indicates potential risks.
- The French Agency for Food, Environmental and Occupational Health & Safety (ANSES) has issued recommendations to mitigate these risks.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
