Quality qualified LED lights do not hurt the eyes; inferior products on the market may be harmful to eyesight.

1. Explanation of terms:

LED energy-saving lamps are a new generation of illumination sources after compact fluorescent lamps (ie, ordinary energy-saving lamps). An LED, a semiconductor light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. LED energy-saving lamps are high-brightness white LED light source, high luminous efficiency, low power consumption, safe and environmentally friendly; suitable for long-term lighting in homes, shopping malls, banks, restaurants and other public places. No flash DC, it has a good protection for the eyes, it is the best choice for desk lamps and flashlights.

2, working principle:

The terminal voltage of the PN junction constitutes a certain barrier. When the forward bias voltage is applied, the barrier decreases, and the majority carriers in the P and N regions diffuse toward each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons diffuse into the P region, which constitutes injection of minority carriers in the P region. These electrons recombine with the holes on the valence band, and the energy obtained during recombination is released as light energy. This is the principle of PN junction illumination.

Therefore, please carefully choose the brand or quality guaranteed LED energy-saving lamps to protect your eyes.
