A variety of light source, LED tube light is more suitable for home!

Every day we live in the light of circumstances, but in fact, whether natural or artificial lighting, lighting source all has red, green and blue light. Among them, the blue part has a certain stimulation on retina. But we just choose the right light, avoid reasonably and scientifically, the dangers of blue light can be controlled within the TVC. Today we take a look at, what is the effect of different light on the eye health. For comparison between several common household lamps light source: incandescent lamp, fluorescent lamp, LED lights, LED spotlights, for example) 。 Bring in household lamps and lanterns, LED downlight, use 1, has been more and more common incandescent lamp and the light bulb, in childhood is almost every necessary to advocate the lamp, but has gradually become obsolete. Full spectrum diagram as shown in the figure below: impact on health: (incandescent lamp spectrum 1) Ultraviolet UV - A content is less, can not consider the effect of ultraviolet radiation on health. （ 2) A high content of near infrared, lighting for a long time can lead to dry skin, easy cause wrinkles; High light surface temperature burns easily. High intensity infrared long-term direct illuminate eye can also cause cataracts. Coupled with the incandescent lamp luminous efficiency is low, great energy consumption, Incandescent lamp runtime, 95% of the electricity consumed in the heating, only 5% of the energy is converted into real can see the light) , short life, Can only use 1000 hours) , low color temperature, have been phased out. 2 common energy-saving lamps, fluorescent lamps, also belongs to the category of the fluorescent lamp, and was widely used in all kinds of lighting environment. Full spectrum diagram as shown in the figure below: impact on health: (fluorescent spectrum 1) Ultraviolet UV - A content is higher, have adverse effects on health. （ 2) Blue light component content is high, the retinal damage may be produced. Fluorescent class contains fluorescent tube, energy-saving lamps, etc. , is used to use a larger light source. As a result of the fluorescent lamp luminous principle is lamp bulb excited by the ultraviolet radiation within the phosphor to produce white light, ultraviolet radiation leaks, long-term use of fluorescent lighting, has certain harm to the skin will be, the color of the skin will turn red, there is a decrease in the moisture content of the skin. Research shows that, under the fluorescent lamp work or study day absorbed by ultraviolet ray, quite an hour in the sun. In addition, the fluorescent lamp also there exists large droop, low color rendering, stroboscopic serious shortcomings, such as long-term use has damage to the eyes, also can bring about mercury pollution on the environment. With the rapid development of LED lighting technology, LED light source price advantage has been close to the fluorescent lamp, with the enhancing environmental protection consciousness, fluorescent lamp also gradually withdrew from the lighting market. 3, LED light source: LED light source is a light emitting diode ( 领导) As the light source of light, its are gradually increasing. Full spectrum diagram as shown in the figure below: impact on health: (LED light spectrum 1) Ultraviolet UV - A content is very few, can not consider the impact. （ 2) Ultraviolet UV - B content. （ 3) Blue light component content is higher, but the color temperature below 3500 k blue light radiation is safe. （ 4) Near infrared content is little, do not need to consider the impact. Beyond traditional light source of LED light source has many advantages, under the same lighting effect, radiation safety of the LED is higher than fluorescent tubes, energy-saving lamps. And good quality, high color rendering index of the LED light blue light radiation is low. Because of the high color rendering means phosphors need to absorb more blue light radiation energy, prompts a wider spectrum, therefore, high color rendering index LED lighting light source is relatively safe. Combined with the LED light source with high efficiency, long life, high reliability, low calorific value, no heat radiation, can accurately control the advantages of the light type and light Angle, and has become a mainstream light source. Now, the LED light source has gradually replace fluorescent lamp and a series of traditional light source, lamps and lanterns represented by LED spotlights, with its own advantages, to better use in the home place, to the person's eyesight health is also a kind of protection.
