[ Chinese wardrobe network ] According to relevant experts, the safety of lighting and lighting system is particularly important for the wardrobe exhibition hall. In addition, the ordinary exhibition lights have the danger that we can not see with the naked eye, infrared rays and ultraviolet rays on the wardrobe. The damage, in which the ultraviolet rays are more harmful. The two kinds of rays provide energy for the chemical and physical processes of the deterioration of the wardrobe. The ultraviolet rays produce photochemical damage, and the infrared rays produce the damage of the physical process.
Compared with the photon activation ability of other visible light, the photon activation ability of ultraviolet rays is several times larger, but its destructive power is far more than these multiples, but is multiplied by N power. This is because many organic substances on the surface of the wardrobe have a strong absorption of ultraviolet rays, thereby activating molecular degradation, but organic matter rarely absorbs other visible light, so ultraviolet rays are more harmful to the wardrobe than other wavelengths, which seriously threaten the furniture. Life expectancy. Therefore, the light source used for the display of cultural relics must avoid ultraviolet rays as much as possible, which is a generally accepted principle in the international museum community.
The activation ability of infrared rays is much smaller than that of ultraviolet rays, but it will cause the temperature of the surface of the wardrobe and the surrounding environment to rise. This is the heat generated by the light we often feel. This heat will exacerbate the ultraviolet rays. The chemical process carried out. Moreover, due to the increase in temperature, the water evaporates, and the surface of the wardrobe is thermally expanded and contracted, which accelerates the aging process.
In fact, we can easily find that when they go to some big home experience halls, they usually don’t turn on the lights. Unless there is a product that the customer wants to see, their shopping guide will turn the light on. This is to prevent the wardrobe from being opened. The principle of damage aging.
