Structure and Principle of Luminous
LED (Light Emitting Diode), light emitting diode, is a solid state semiconductor devices for power into visible light, it can be directly converted to electric light. Heart of the LED is a semiconductor chip.
led tube lighting chip is attached to a bracket at one end, one end is negative and the other end to connect the power of positive, so that the whole chip is epoxy encapsulated. Semiconductor wafer is composed of two parts, part of p-type semiconductor, dominated it inside the hole and the other end is an n-type semiconductor, here is primarily electronic. But when it connects both semiconductors, form a p-n junction between them. When current through conductors on the chip when e is to the p-, p-electrons with holes in compound and will be issued in the form of photon energy, which is the principle of the LED lights glow. And the wavelength of light that is the color of the light is determined by the materials forming p-n junction.
LED Fluorescent Lamp
Led fluorescent lamps have features of high quality, durable and energy-saving, wide projection angle adjustment range, and brightness equivalent to an ordinary 40W fluorescent lamp 15W. It's resistance to high temperatures, moisture-proof and waterproof, leak proof. LED fluorescent lamp using the latest LED lighting technology, digital design, and power saving over 70%, 12W LED solar light intensity equivalent to 40W fluorescent tubes (used for ballast and Starter, real power consumption 36W fluorescent lamp 42W). LED fluorescent lamp life is 10 times more than ordinary lamps, virtually maintenance-free, no need to frequently replace the lamp, ballast, and starter. Green semiconductor lighting, soft light, spectral purity, vision in flavor of consumer protection and health. 6000K cold light source gives a visually cool, humanized illumination design differences, but also help concentrate and improve efficiency.
Application of LED Lights
Initially China led tube as instruments and meters indicate the light source, then all light color of LED traffic lights and has been widely used in large-area display, resulting in a very good economic and social benefits. With 12-inch red traffic lights, for instance, in the United States LED line lights. Is the use of long-life, low luminous efficiency of a 140-watt incandescent lamp as a light source? It produces 2000 lumens of white light. The red filter, 90% light loss, only 200 lumens of red light. In light of the new design, Limitless Corporation has adopted 18 red LED light sources, including circuit, loss, total power consumption 1w; you can produce the same luminous efficiency. Car lights are also important areas of LED lighting applications. In 1987, China began to install high brake lights on the car, due to fast LED response speed (nanosecond), early and let drivers know the operating conditions of the vehicle, reducing vehicle rear accidents occur. In addition, the LED lights red, green, and blue outdoors full color display, Key ring micro torch has been applied in the field.
