LED floodlights will lead the "fashion"

Fashion & Cosmetics,Collecting,Free Web Resources
Under the background of global warming, energy-saving emission reduction has become a hot spot and focus the world, the voice of low energy consumption and no pollution LED lighting industry is louder, the world has raised the upsurge of investment LED. With the new city advocating energy saving and environmental protection and accelerating the process in our country , LED floodlights will also lead the lighting "fashion".

LED (Light Emitting Diode), light-emitting diode, adopt solid state semiconductor devices, which can be directly converted into electricity to light. The heart of LED is a semiconductor wafer, the wafer is attached to a stent, is the negative side, the other end is connected to the power of the cathode, the entire chip is packaged by epoxy resin. Semiconductor chip is composed of two parts, one part is a P type semiconductor, the hole is dominant inside it, the other side is the N type semiconductor, here is mainly electronic. But linking the two semiconductor, a "P-N junction is formed between them". When the current through the wires on the chip, the electron will be to P area, complex in area P of electrons and holes, and then to form a photonic energy, this is LED light-emitting principle. The wavelength of light is the color of light, which is determined by the formation of P-N junction material.

The advantage of LED floodlights

LED floodlights is able to get the attention of lighting professionals, has so big development potential of the lighting field, because compared with traditional light sources, it has the following characteristics.

1.visible light with high efficiency At present, LED floodlights luminous efficiency is not high, but the visible light spectrum efficiency of LED is high, almost all concentrated in the visible light spectrum, without filtering can directly emit colored light. Now LED visible light efficiency after improvement has reached 50-110 lm/W, and incandescent lamps, halogen tungsten lamp light efficiency is 12-24 lm/W, a fluorescent lamp light efficiency is 30-70 lm/W, sodium lamp visible light efficiency for 90-140 lm/W. As countries improve the study of LED light effect around the world, the LED luminous efficiency will have a greater increase in the near future,,LED lighting will have higher efficiency of the visible light.

2. pure colors Unlike incandescent lamp band spectrum, LED spectrum is narrow, the light is very pure. A certain peak wavelength LED determine the luminescence color, can now produce several red, orange, yellow, green, amber, blue, purple, white and other colors of LED, after mixing can realize the full spectrum color after appropriate implementation

3. less power consumption LED floodlights power is generally in the 0.03 ~ 1W, through the cluster can meet the various needs of modeling, because almost no ultraviolet and infrared spectrum, so the low heat, no radiation damage. When it needs color light and white light through the filter, its natural color avoid consuming time and energy,under the same illumination circumstances, power consumption is 1/8 of the incandescent light bulb and 1/2 of fluorescent tube. Take the guardrail lamp for example, a fluorescent lamp power consumption is more than 40 W, and the LED floodlights only 8W. China Green Lights Project Office made a special investigation, China lighting electricity annually consume more than 300 billion degrees, use L E D light to replace or partly all the incandescent lamp will save 1/3 electricity for lighting, it means saving 100 billion degrees, equivalent to the Three Gorges Project generating capacity of more than a total investment of 200 billion in a year. The energy is very tense in China, undoubtedly has a very important significance.

4. safety and reliability and long service life LED light source adopt the solid luminous body, soft silicone package, the lamp body has no loose parts, lamp has the advantages of small volume, light weight, shock resistance is strong, not easy to be broken, there is no filament light-emitting burn ability, thermal deposition and other shortcomings, stable performance, can work normally in -30 ~ +50oC environment, the above service life is up to 50000 hours, has more than 5 times service life than the traditional light source. Can greatly reduce the maintenance cost of the lamp and pain of frequent replacement.

5. flexible application Small volume, plane package, easy to develop into a short thin products, can be made into specific applications point, line, face various forms; fast reaction speed, frequent operation; the built-in microprocessor system can control the luminous intensity, adjust luminous way and realize the combination of light and art.

6. durable LED floodlights is completely encapsulated in epoxy resin inside, it is stronger than light bulbs and fluorescent tubes. The lamp body has no loose parts, these features make the LE D can not easy to be damaged.

7. conducive to environmental protection LED floodlights source belongs to cold light source, the monomer between the working voltage of 1.5 ~ 5V, between the working current of 20 ~ 70mA, safe touch, no risk, no mercury, sodium and other potential health hazards of material, scrap recyclable, no environmental pollution, and belongs to the typical green lighting source.
