Harm of LED eye protection lamp in toto bathtub

1, some "eye protection lights" emit too strong white light, which makes reading and writing in this light dazzling. After a long time (generally more than 15 minutes), eyes will feel tired or sore.

This is because yellow light is the most acceptable spot for human eyes (that is, the background color of eyes is acceptable), which is why reading and writing under yellow light will feel soft and comfortable.

2. The ultraviolet rays produced by fluorescent lamps will do some harm to students' eyes and skin.

Fluorescent lamps must be excited by ultraviolet rays to emit light, and ultraviolet disinfection lamps use this principle to produce ultraviolet disinfection.

So all fluorescent lamps will produce ultraviolet rays.

The ultraviolet rays generated by fluorescent lamps will cause certain harm to human eyes within the distance of 1-2 meters, and the harm will be aggravated when it is less than 0.6 meters.

Since fluorescent lamps are generally far away from the human body (at least 2.5 meters above), the ultraviolet rays generated by fluorescent lamps do not harm people.

The distance between the "eye protection lamp" with fluorescent tubes and students is generally less than 0.6 meters, so the ultraviolet radiation it produces will cause harm to people.

If exposed to ultraviolet rays for a long time, it will cause damage to the lens and retina of the eye, leading to decreased vision and even blindness.

3. Another problem of "eye protection lamp" with high-frequency rectifier (that is, the energy-saving lamp you see every day) is electromagnetic radiation.

The main selling point of the so-called eye protection lamp is that there is no stroboscopic light, which means that the light of this lamp is stable and will not flicker.

This lamp uses high-frequency electronic ballast to adjust the current frequency to 30-50kHz, that is, the flashing speed of light is increased to tens of thousands of times per second.

The problem of high frequency electronic ballast is that it will produce electromagnetic radiation, which is harmful to human body.
