The wedding lights are bright. As long as there is light, there is radiation, but there are three kinds of sunlight, namely UVA, UVB and UVC, because it has ultraviolet rays. However, UVC is the only barrier of ozone layer, and it can't harm people's skin. UVVB is the daily ultraviolet light. Only indoors will there be strong outdoor sunlight, which will cause UVA for a long time.

Compared with natural light, wedding lighting lacks ultraviolet rays, which does not meet the normal physiological needs of human body. The light of fluorescent lamps contains some ultraviolet rays invisible to the naked eye. Frequent short-distance contact with these strong light waves may cause variation of body cells. It is harmful to the health of the fetus and pregnant women.
