LED lighting-emitting principle and advantages

LED lighting-emitting principle and advantage: LED light-emitting diode is short. By the gallium (Ga) and arsenic (AS), phosphorus (P) compounds made of diodes, when the electron and hole recombination radiation when visible light, which can be used to make light-emitting diodes in the circuit and equipment as instructed lights, or the composition of text or figures. Of red phosphorus and gallium arsenide diodes, gallium phosphide diode glow green, yellow hair silicon carbide diodes. At present there can be issued a similar incandescent light color LED, which provides a modern lighting, long life, high efficiency lighting, the most valuable is, LED devices with up to 50,000 or even 100,000 hours life, for many occasions the application characteristics.
LED light with natural light is different, the spectrum is not continuous, the lack of the infrared part, so different with incandescent lamps, LED by the radiant heat generated is not shed, but must be shed by conduction, which is known as cold- LED strip of reason. LED has the following advantages:
Energy efficient: the white LED is now known to most energy-efficient white light source of the device. Power consumption of only a few degrees one thousand hours (regular consumption of a 60W incandescent seventeen hours of electricity, the general consumption of 10W energy saving lamp one hundred hours of electricity)
Long life: light-emitting semiconductor chip, no filament, no glass bulb, afraid of shock, not broken, the service life of up to 50,000 hours (incandescent only a few hundred hours of life, ordinary life of energy-saving lamps only eight thousand hours )
Green: No harmful elements such as mercury and xenon, is conducive to recovery and use, and will not produce electromagnetic interference (ordinary lamps contain mercury and lead, elements, energy-saving lamps, electronic ballasts will produce electromagnetic interference, and light mercury tubes still exist)
Eye protection: DC drive, no flash (normal lights are AC drive, it will inevitably produce strobe)
Light efficiency: small heat: 90 percent of electricity into visible light (incandescent 80% of the energy into heat, only 20% of electrical energy into light energy)
Market potential: low voltage, DC power supply, battery, solar power can be can be used for outdoor lighting in remote mountainous areas and lack of electricity, less electricity places.

How to locate housing LED lamps

Development of LED lighting to the present, I believe many of my friends are often seen lighting LED lighting products on the market, the appearance is strange, no matter what kind of product, there are a lot of shape, of course not the same price as some of the mainstream LED lamp, LED bulb, LED fluorescent interior lighting such, businesses in order to occupy a certain market, both in appearance and down a lot of effort, to go into research and development, looking at the shape of the case, how to control costs has become a business issues
May now look, LED lighting, many businesses have to fight the cost, how to control costs, the corresponding control on the price to win market access to the pre-edge analysis, and now the LED lighting market, the appearance of the product are is aluminum-based design, because of its great heat and aluminum prices in the ratio of the two is the best, a lot of LED strip manufacturers in product design are inseparable from the aluminum, after all now the LED lighting market, that price has already started a number of factors in it, who do not want to own the product does not have any advantage in price, although the direction of each business and different strategy, take the high road, perhaps the price is high in the general market price, but for the general public consumers, is unbearable.
For the shell material is concerned, LED lighting, the next few years will be mainly based on aluminum, it is necessary to ensure that production costs but also to ensure that its heat, cooling, after all, is a hard technical indicators, if you can not do enough heat, a LED lamp life of finished product will have great impact, and for continued development and progress of the LED lighting industry, which is a long-term progress of the process, materials, thermal problems can be solved, it will turn to the pursuit of appearance, with the LED lighting market popularity, people accept the LED lighting products, LED lighting products will also be critical, choose, and no one product or industry, if you want to continue to develop and advance the process, must face.
