At present, the microscope lighting method can be divided into two types of transmission and lighting. The illuminated light beam is emitted from the direction of the objective lens to the surface of the object to be observed, emitted or diffracted by the surface of the object, and then returned to the objective lens. Therefore, the ejection lighting is mainly used for observing metals and opaque objects such as ores, insects or circuit boards. For the fine observation of the circuit board PCB, in particular, need to observe the fine lines, requiring the microscope lens is close or close to the observation, the objective lens is basically attached to the circuit board, based on existing LED Light Source or Halogen light source lighting system can not achieve light focus, it is difficult to achieve litter lighting.

Optical fiber is a glass or plastic made of fiber, which can use the "light of the total reflection" principle as a light transmission tool. The propagation of light in any medium will be lost due to absorption and scattering, but some measures can be taken to reduce the loss of light over long distances. This includes: the use of ultra-pure quartz glass to reduce impurities in the optical fiber; try to improve the internal structure of the glass uniformity; the use of long wavelength of laser conduction, in order to improve the transmission of optical fiber effect. HECHO choose imported high transmission rate of Germany Schott glass fiber and Japan's Mitsubishi, Asahi Kasei, Toray plastic optical fiber materials, to produce various Fiber optic bundles, Optical fiber sensors and other fiber optic products, to provide complete Fiber optic transmission solutions to meet the industry's use of the environment and application.

In optical fiber lighting, because the optical fiber is only a carrier of light transmission, so the inevitable need to support the choice of Cold Light Source. The so-called cold light source, is issued by the light emitted by the heat generated part of the infrared light filter effectively. We in the market common lighting with cold light source is divided into metal halide lamp cold light source, halogen cold light source and LED cold light source. Metal Halide Lamp Cold light source is characterized by luminous efficiency can reach 80-90 lm / W, color rendering index can reach 90 or more. Spectral range is relatively wide, good quality metal halide bulb life can generally reach about 5,000 hours. Where the need for high-intensity lighting, metal halide lamp cold light source is a common choice, the disadvantage is its high price, start the need for specialized flip-flop, because its brightness is gradually increased after startup, start more slowly. Halogen 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 optical fiber cold light source, the halogen bulb matches with the ellipsoidal reflector cup to gather light. The use of power is generally 50-250W, because of its luminous efficiency in general, more than 100 watts of power use, the convergence point of light after the temperature will be very high, so halogen light source in the selection of the need to pay attention to its heat insulation and heat dissipation, If there is no effective treatment, the focus of the high temperature will burn out the end of the fiber. LED cold light source in recent years the fastest-growing products. White LED light source color temperature in the 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, the gradual use of LED cold light source. White LED light source is the cold light emission spectrum is not a continuous spectrum. At the same time Fiber Optic LED Light Source LED light-emitting chip angle is relatively large, coupling optical fiber requires secondary optical distribution, secondary optical light distribution efficiency of its overall effective output is very important, so the higher the power is not the higher its illumination value , More importantly, depends on its effective output of the luminous flux parameters. In summary, in the choice of optical fiber lighting supporting the cold light source, if the spectrum has a higher demand, you can choose metal halide lamp cold Fiber Light Source and halogen light source, if the service life and control response speed may be required, can Select LED cold light source. With the continuous development of LED semiconductor technology, more high-power LED light-emitting chip is also constantly introduced, the effective luminous flux output will be higher and higher, coupled with optimized secondary optical design, overall over metal halide lamp cold light source And the effective output of the halogen lamp cold light source is entirely possible. At the same time several cold light source, need to pay attention to its thermal design, whether the effective isolation of the infrared light part of the light.

LED Light Source is more and more common in our daily life, the traditional fluorescent lamp has slowly be replaced, the LED light source some advantages compared with the traditional fluorescent lamp and characteristics? Under the nanjing hecho according to science and technology is to introduce for everybody. Using range: LED use the low voltage power supply, it is a safer than using high voltage power supply power supply, especially suitable for the public. Applicability: small, each unit of LED is 3 to 5 mm square dice, so can be prepared into various shapes of the device, and is suitable for variable environment Reflect fast: its response time of millisecond incandescent lamps,Fiber Optic LED Light response time for nanosecond level 6 High color rendering: LED high color rendering, won't cause harm to people's eyes

LED cold light source has been widely used in the field of medical lighting, products are also emerge in endlessly, that how to choose an appropriate medical cold light source? For the performance of LED itself, Nanjing hon technology suggestion from the following consideration. 1, the detection of life: medical endoscope using normal halogen lamp and xenon lamp is only a short life of hundreds of hours, often need to change the light bulb, and we are LED endoscopic module 60000 hours service life; 2, information of LED cold light source characteristics, design the optical system with high efficiency, endoscopic LED module brightness increased by more than 30%. 3, test its uniformity is good: endoscopic LED module light irradiation area without spots dark space, light even and soft. 4, check the order with a channel, LED drive current 25 a, ensure the LED light bright enough, there are more than 5000 lm luminous flux, fiber optic illumination value in more than 2 million lux (different) fiber have different test result. 5, pay attention to choose the cooling system, using efficient heat conduction medium, to ensure the service life. Normal use conditions of the LED as far as possible to reduce costs, simple way to set a good effect.

Fiber optic lighting is a new way of lighting in recent years. As a result of the optical fiber itself has some unique physical properties, fiber optic lighting are used in interior decoration lighting, effect of local lighting, billboard lighting, direct lighting, indoor and outdoor building outdoor public area underwater lighting and building outline and the facade lighting, and have achieved good lighting effect.
