LED the desk lamp that shield an eye eye really?

Answer:

Use eye, as long as the light is a kind of damage, the difference is only the size and the third, of course, is impossible, with the eye is not light lamp of choosing a cross-eyed least damage is completely necessary, by contrast, leds regardless of the effect, efficiency, and a huge step forward in principle, is the most close to natural light in all the light source of human invention. It is believed that you have to know. Just led lights there are pros and cons, now led market good rust is not neat, the size of the brand, the price have jet lag for a few times, but as long as it is more adept or understand led people have a better method, is a choice of using high power led lamp bead light is guaranteed!!
Since the traditional inductive common fluorescent lamp, there will be a light blinking. Alternating current frequency is 50 hz, so common fluorescent lamp is 50 times per second periodic start-stop, due to the human eye persistence of vision effect and the effect of the fluorescent tube wall afterglow phosphor, normally would not be aware of the light blinking. But in the long-term work under this kind of light source, especially in fine operation, it is easy to produce visual fatigue and with a series of symptoms, namely, commonly known as the "eyes", so before the desk lamp of recommend the use of incandescent lamp it is for this reason. Can be fluorescent characteristics of high relative to the incandescent lamp brightness, save electricity, but can't. With the emergence of electronic ballasts, fluorescent lamp start-stop frequency from 50 hz to several - KHz, greatly reduce the flicker effect, alleviate the occurrence of visual fatigue and even can be used in a high-speed movement of the venues (table tennis, badminton) lighting, visible flicker of already fell to very low, manufacturers take this selling point and with the attractive word "eye", a little fool. Since it is not what is the role that shield an eye really, but reduce the damage to the eyes to the technology of controllable minimum. Lighting white LED, as the breakthrough after blue light LED manufacturing technology in recent years. Due to the LED light emitting diode) is a dc power supply, as long as and qualified drive power match, there is no so-called flashing, says it is "eye" a bit redundant, stir-fried concept. Every brand has a high school low-grade products, cannot treat as the same. In accordance with individual psychological orientation is good. Personal humble opinion, only supplies the reference.
