Introduction to the basic knowledge of LED lighting engineering

LED lighting project refers to an energy-saving, emission-reduction and high-efficiency project that uses the latest LED lighting technology to reduce energy consumption, reduce exhaust emissions, and improve urban lighting brightness. Advantages of solar street light The inherent characteristics of LED determine that it is the most ideal light source to replace the traditional light source, and it has a wide range of uses. 1. Small size LED is basically a small chip encapsulated in epoxy resin, so it is very small and very light. 2. Low power consumption LED power consumption is very low. Generally speaking, the working voltage of LED (de0 gong1 zuo1 dian4) is 2-3.6V. The working current is 0.02-0.03A. That is to say: it consumes no more than 0.1W. 3. Long service life Under the proper current and voltage, the service life of LED can reach 100,000 hours. 4. High brightness, low heat (si4 _gao1 liang4 du4 _di1) . 6. Sturdy and durable LED is completely encapsulated in epoxy (shi bei wan quan de feng zhuang zai huan yang) resin, which is stronger than light bulbs and fluorescent tubes. There are also no loose parts in the lamp body, these features make the LED not easy to damage. High energy saving: energy saving and non-polluting energy are the guarantee of the environment. DC drive, ultra-low power consumption (single tube 0.03-0.06 watts) electro-optical power conversion is close to 100%, the same lighting effect saves more than 80% energy than traditional light sources. Long life: LED light source is called longevity lamp, which means the lamp that never goes out. Solid cold light source, epoxy resin encapsulation, no loose parts in the lamp body, no shortcomings such as easy burning of filament, thermal deposition, light decay, etc. The service life can reach 60,000 to 100,000 hours, which is 10 times longer than traditional light sources above. Changeable: LED light source can use the principle of red, green and blue three primary colors, under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can generate 256×256×256u003d kinds of colors, forming different light colors The combination of various changes, to achieve a variety of dynamic changes and various images. Environmental protection: better environmental protection benefits, no ultraviolet and infrared rays in the spectrum, no heat, no radiation, low glare, and recyclable waste, no pollution, no mercury, cold light source, safe to touch, typical green Lighting source. High-tech tip: Compared with the monotonous luminous effect of traditional light sources, LED light sources (guang1 yuan2) are low-voltage microelectronic products that successfully integrate computer technology, network communication technology, image processing technology, embedded control technology, etc., so they are also digital information. It is a 'high-tech' technology for semiconductor optoelectronic devices, with the characteristics of online programming, unlimited upgrades, and flexibility.
