1, most consumers do not know the dynasty Biosafety
Consumers to buy lighting most concerned about the safety of its leakage, but often overlooked light Biosafety, household led lights, some have even heard of the photobiological safety.
“Light bio-security” can be understood as “optical radiation”, that is issued by the light source or lamp spectrum, in addition to visible light, ultraviolet nuclear infrared light on the glasses and skin will produce different degrees of the photochemical hazards of ultraviolet and infrared radiation (heat) hazards.
Band of optical radiation, household led lights, especially ultraviolet and blue bands on the human body. LED spectrum have different proportions of UV and blue spectral bands in the visible blue light part will the retinal pigment epithelium damage. Has been found that several light radiation hazards are: light-induced keratitis and light induced conjunctivitis, cataract, retinal burns, household led lights, retinal blue light damage, tanning, UV erythema, skin aging, skin cancer.
Multi-chip integration and the second optical design technology development, so that the LED chip power and external quantum efficiency of the increasing ultraviolet and blue-band short-wave LED chips are widely used, technology and market share increase more significant dangers of making the LED . Different from the daylight, led high bay the LED is the use of a specific wavelength components of monochromatic light through the light distribution program simulating natural light, the light source spectrum is not continuous, monochromatic light of the specific components of high-brightness characteristics. In addition to the human eye, household led lights, the retina there is a potential threat of injury, short wavelength blue light, the pineal gland to produce melatonin significantly lower than other types of artificial light. Studies have pointed out that the blue component in the continuous output spectrum of the LED light source has a normal rhesus monkey retina injury; too strong shortwave blue light easily lead to the degradation of photochemical damage of the retinal photoreceptor cells and pigment epithelial function, is too strong radiation can also cause thermal damage of the retina.
