Color rendering refers to the objective effect produced by light emitted by a light source on an object and the degree of appearance of the true color of the object, which is an important indicator of the illumination light source. The light source with high color rendering performs better on the color, the color seen is close to the natural color, and the light source with low color rendering performs poorly on the color, and the color deviation seen is also large. If the light emitted by the light source contains a proportion of each color of light that is similar to natural light, the colors seen by the human eye are more realistic. The spectral distribution of the light source determines the color rendering of the light source. The color rendering of the light source affects the color of the object observed by the human eye. Quantitative evaluation of the color rendering property of the light source is an important indicator for evaluating the quality of the light source. General artificial lighting sources use the general color rendering index as an evaluation index of color rendering, and the color rendering index is also an important parameter to measure the color characteristics of the light source. According to different application fields, Nanjing Hecho Technology Co., Ltd. launched a new ultra-bright high color rendering index medical Endoscope Light Source Module; ultra-high brightness LED Cold Light Source, and Fiber Optic Illuminators and other products to meet the needs of different customers, welcome The majority of new and old customers to inquire.

The core is the central region where the refractive index of the transmitted light in the optical waveguide is higher than that of the adjacent region. For the step-type refractive index distribution fiber, the core is a cylinder containing a fiber core with a high refractive index. As the optical Fiber Optical Transmission layer called cortex, also known as cladding, for the step-like refractive index distribution fiber, the cortex is the lower refractive index of the ring outside the core, see the following figure. Optical fiber coating layer is coated with a layer of protective fiber material, referred to as fiber coating, also known as coating or buffer layer or fiber coating, optical fiber coating not only has to maintain fiber strength, to prevent fiber micro Bending loss and the ability to prevent fiber damp, but also reduce the mechanical damage of the fiber, and some fiber coating also has a specific physical variables sensitive to the characteristics can be used for sensing measurements, the typical coating materials, including acrylic resin, silicon Resin, ethylene-tetrafluoroethylene copolymer, polyurethane and polyimide, see the following figure. The cladding mode is a mold that is transferred and held in the fiber cortex. Usually, a cortical material that absorbs or attenuates the cladding mode is used to prevent the transition of the cladding module energy into a core, Thus reducing the dispersion, cladding mode, also known as cladding mode. Hecho specializing in manufacture Fiber Optic Cables, Fiber Optic Bundles, Fiber Optic Sensors, and Fiber Optic Illuminators for over 10 years. We supply a complete solution for Optical Fiber transmission. OEM service is welcome.

Optical fiber (referred to as fiber) has a lot of types. According to the materials used in the manufacture of optical fiber classification as Quartz Fibers, Multi-component Glass Fibers, and Plastic Optical Fibers. According to the light in the fiber transmission mode can be divided into: Single-mode fiber and Multi-mode fiber. Cross section Refractive index Light propagation Fiber types Multimode - step refractive index Single mode - step refractive index Multimode - gradient refractive index The optical fiber is classified on the one hand according to the refractive index distribution of the core profile, and on the other hand, according to the number of patterns transmitted. As described above, it is divided into single-mode optical fiber and multimode optical fiber. According to the profile refractive index distribution is divided into step optical fiber, gradient refractive index optical fiber and special profile refractive index distribution optical fiber. Step Refractive index The refractive index of the optical fiber over the entire cross section is constant. Gradient Refractive Index The optical fiber cross section is non-linear, rotationally symmetric, and the refractive index decreases from the center to the edge. Step Refractive index The refractive index of the multimode optical fiber is constant, so its distribution index g = α. Gradient Refractive Index The refractive index of the optical fiber decreases from the center to the edge. The light travels along the axis of the optical fiber, rather than straight. Nanjing Hecho Technology Co., Ltd. supply glass fiber, plastic optical fiber and quartz fiber products, including Fiber Optic Bundles, Fiber Optic Sensors, Fiber Optic Cold Light Source, please call us freely!

Fiber Optic Bundles is the core component of fiber optic lighting, the bundle is generally composed of optical fiber material, interface and protection tube composition. How to choose a suitable Light Guide? First, we determine the spectral requirements used. In general use, the spectrum is generally divided into three parts. UV to visible light (190nm-1200nm), visible light (380-780nm), visible to near infrared (400-1400nm) Far infrared part (400-2500nm). The four parts correspond to the optical fiber materials of different materials. (380-780nm) Optional plastic optical fiber or glass fiber, visible to near infrared part (400-1400nm), optional glass fiber, visible to far infrared part (400-2500nm) Optional infrared fiber. Second, according to the use the environment to determine the use of temperature range, glass fiber and quartz fiber can withstand higher temperatures, plastic fiber generally can only withstand 75 degrees or less. At the same time fiber in the production need to use adhesives, conventional fiber adhesive temperature within 180 degrees, if the use of temperature higher than 180 degrees, need to choose a higher temperature resistant high temperature fiber adhesives. At present the general high temperature fiber adhesives can work long-term 350 degrees. Third, confirm the shape of fiber, generally summarized the Fiber Optic Bundle has the following shapes, Single Light Guide, double-tube, multi-branched light guide, Ring Light Guide, linear light guide, multi-input multi-output type. After determining the shape, the dimensions of the parts at both ends of the optical fiber bundle are determined simultaneously. At the third step, the fiber bundles need the protective tube, such as stainless steel tube, stainless steel outer plastic coated tube, etc. Hecho supply OEM service for Fiber Optic Bundles, Fiber Optic Sensors and Cold Light Source, if any related items required, pls contact us freely.

In the fiber optic lighting, due to the optical fiber is only a light transmission carrier itself does not light, so inevitably need to choose the cold light source. The cold light source, is the light emitted by the light generated in the heat part of the infrared light effectively filtered out. We are common in the market with cold light source is mainly divided into Metal Halide lamp cold light source, Halogen Light Source and LED Cold Light Source. Metal halide lamp cold light source is characterized by luminous efficiency can reach 80-90 lumens / watt, color rendering index can reach more than 90. Spectral range is relatively wide, good quality metal halogenated lamp life can normal use around 5000 hours. Where the need for high-intensity lighting, metal halide lamp cold light source is a common choice, the disadvantage is its relatively high price, start requires a special trigger, because its brightness is gradually increased, start more slowly. Halogen lamp cold light source is characterized by luminous efficiency is generally 30-50 lumens / watt, color temperature is generally 2700-3200K, color rendering index is generally more than 80. The rated life of the lamp is 50-1000 hours. Generally in the fiber cold light source, the halogen bulb with ellipsoid reflector condenser. The use of power is generally 50-250W, because of its luminous efficiency in general, more than 100 watts of power use, the convergence of light after the focus point temperature will be high, so the halogen light source in the selection of the need to pay attention to its insulation and heat, If it is not done effectively, the high temperature generated by its focus will burn out the end face of the fiber. LED cold light source is the fastest growing product in recent years. White light LED light source color temperature 2700-6500K, color rendering index 70-92, the service life of up to 30,000 hours because of its high luminous efficiency, fast response and long life, the overall power of small energy saving, so more and more Occasions are gradually using LED cold light source. The white light of the LED cold light source defect is that its emission spectrum is not continuous spectrum. At the same time LED light source light-emitting chip luminous angle is relatively large, the coupling fiber requires secondary optical light distribution, secondary optical light distribution efficiency of its overall effective output is very important, so the power is not the higher the higher the illumination value , More important is to see the effective output of the luminous flux parameters. In summary, in the choice of fiber optic lighting supporting the Cold Light Source, if the spectrum has a higher demand, you can choose metal halide lamp cold light source and halogen light source, if the service life and control the response speed requirements Choose LED cold light source. With the continuous development of LED semiconductor technology, more powerful LED light-emitting chip is also constantly introduced, the effective luminous flux output will be higher and higher, coupled with the optimization of the secondary optical design, the overall over the metal halide lamp cold light source And the effective output of the cold light source of the halogen lamp is entirely possible. At the same time more than a few cold light source, need to pay attention to its cooling design, whether the effective isolation of the light part of the infrared light.
