【正文】 s first to market a POF [1], POF is an optical fiber, and fiber optic fiber optic lighting for the basic principle is to use light in the interface of different refractive index total reflection, to achieve high optical transmission in optical fibers and optical fiber coupled with a sufficient light source, and through a bination with a variety of optical ponents to achieve the desired lighting effects, to understand the transmission of light in fiber mode, are presented in the meridional ray POF in the transmission characteristics. 2. The basics of light Light through the light source in a large number of molecular or atomic radiation generated vibration. In 1894, Maxwell theory that light is an electromagnetic wave, Einstein proposed in 1905 alone, a piece of particle flow, each particle can be called photons. That is both a particle nature of light, they are volatile, when the light showed in the dissemination of volatility, but the performance and matter for the particle nature of the role of Shiyou. Usually we are talking about a light wave, usually from the ultraviolet, visible and near infrared light, posed of 1390nm wavelength UV light is UV, wavelength 280300nm wavelength of UVB, it light can kill or seriously damage life on Earth。光在真空中的傳播速度是最快的，傳輸介質(zhì)不同，其折射率不同，傳光速度也不同。光在透明柱體中通過(guò)多次全反射向前傳播的現(xiàn)象，他們就是古代的玻璃吹制藝人。 390760nm波段的光為可見光；波長(zhǎng)在7601500nm為近紅外光，遠(yuǎn)紅外光譜波長(zhǎng)范圍25300μm,比遠(yuǎn)紅外光頻率更小或波長(zhǎng)更長(zhǎng)的有毫米波、微波、短波、中波和長(zhǎng)波等。 fiber optic lighting, the choice of optical fiber, optical fiber materials according to different, often can be divided into quartz fiber, multiponent glass fiber and plastic optical fiber POF, etc. This paper introduces POF principle of the transmission of light, the other optical fiber transmission principles with the transmission of light POF principle is the same. Perceives light in a transparent cylinder in the forward propagation through multiple total reflection phenomenon, they are the ancient glassblowing artists. The first described the phenomenon of science, but it is the Royal Society, John ? Tyndall demonstrated to the British Royal Society, a famous experiment, he was filled with a water vessel, so that water from the vessel39。 wavelength of 7601500nm for the nearinfrared light, the infrared wavelength range of , far infrared spectrum wavelength range 25300μm, more than farin
