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. What are the typical features of the Fiber Optic Lighting Source? Hecho Summarized the following points. 1. A single light source can have multiple luminescence properties of the same markers; 2. The light source is easy to replace，also easy to repair 3. Light emitting device can be placed in the position of the non-professional personnel to contact，Therefore, to prevent destructive 4. No ultraviolet and infrared light, can reduce damage to certain items such as cultural relics, textiles; 5. Markers in miniaturization, light weight, easy replacement, installation, can be made into a small size；Small objects placed in a glass or other inner glow form special decorative lighting effect 6. No electromagnetic interference, can be used in nuclear magnetic resonance room, radar control room and other special site has electromagnetic shielding 7. No spark, no electric shock risk, can be used in chemical, oil and gas platform, fountain pool, swimming pool, etc have fire and explosive risk or damp and water of a particular place 8. Light color can be changed automatically 9. Reusable, save investment 10. Soft and easy to fold non-friable, easy to be processed into a variety of different patterns.
