Do fluorescent lamps have ultraviolet rays?

As we all know, under normal sunlight, long-term exposure will lead to skin blackening, which is caused by ultraviolet rays contained in sunlight, which is relatively weak. If it is high-intensity ultraviolet light, it will even cause pathological changes in human cells, which is quite scary. So do the fluorescent lamps we use every day also contain a lot of ultraviolet rays? Is it harmful to human body? Here are some answers for you.

Nowadays, the fluorescent lamps used by everyone are divided into traditional fluorescent lamps and new LED fluorescent lamps. Both of these lamps use ultraviolet rays to excite the luminescent substance inside the lamp tube to emit light visible to our naked eyes, so as to stay away from the light. Although the fluorescent lamp is excited by ultraviolet rays, the ultraviolet rays in the lamp will not directly irradiate the human body through the lamp, but will be absorbed in the lamp. If we are worried that a small amount of ultraviolet rays will overflow after long-term use of the lamp, we just need to stay away from the light source of the lamp, which will not cause harm to the human body. Because the farther the distance, the lower the intensity of ultraviolet light.

At present, there are traditional fluorescent lamps and new LED fluorescent lamps for you to choose from. Compared with the price, LED fluorescent lamps are slightly more expensive, so what's the difference between traditional fluorescent lamps and new LED fluorescent lamps? Let's compare it.

1, the light emitted by the new LED fluorescent lamp is soft and uniform, which is not easy to cause visual fatigue, while the traditional fluorescent lamp occasionally appears stroboscopic and glare, which is easy to cause visual discomfort.

2. Compared with the traditional fluorescent lamp, the new LED fluorescent lamp is more energy-saving, but the brightness is higher, because the new LED adopts strip divergent light source, and the luminescent material is rare earth instead of halogen powder of the traditional fluorescent lamp, so the driving voltage is low and the calorific value is less, which is about twice as energy-saving as the traditional fluorescent lamp.

3. The new LED lamp does not need auxiliary components such as ballasts and up-converters, and there will be no problems such as stroboscopic and glare, and it is safer and more reliable because it adopts flame retardant materials with higher temperature resistance.

4. Traditional fluorescent lamps mean a lot of mercury vapor. We all know that mercury is also called mercury, which is harmful to human body. Once broken and cracked, a large amount of mercury will volatilize into the air, causing harm to human body. The new LED lamp contains no mercury, which is non-toxic and harmless to human body, and it is a relatively environmentally friendly product.

Although fluorescent lamps are excited by ultraviolet rays, these ultraviolet rays basically exist only in the inside of the lamp tube, which is much less than the ultraviolet rays we usually contact in the sun, so we don't need to worry too much about the safety of ultraviolet rays. If you want to buy lamps, I personally suggest choosing a new type of LED, which is energy-saving and environmentally friendly and has a long service life.
