LED lights will gradually replace the traditional lighting fixtures

With the concept of LED energy conservation and environmental protection as well as the spread of ideas more widely, from LED commercial lighting to home lighting, companies have increased R & D to a more powerful LED won the broad market. The rise of LED lighting companies show that LED is gradually affecting the traditional consumer demand for lighting, energy saving from LED to a variety of creative modeling, paving the wide application of LED. In the process of iterative products and explore the needs of users, along with the establishment of the new LED lighting companies, there will be more traditional lighting into the field of LED. LED replace the traditional lighting is the inevitable direction in 1938, the United States Universal Electronics Inc's Iman invented a fluorescent lamp. The fluorescent lamp depends on the electron to hit the fluorescent powder to shine, does not consume the energy waste in the heat, the electric energy utilization ratio has the very big enhancement. But the fluorescent lamp contains mercury and lead, on the human body and the environment has great harm, still does not meet the needs of sustainable development. With the continuous development of technology, energy saving and environmental protection of the new generation of lighting technology LED began to enter people's vision. LED can transform electrical energy directly into light, which has solved the incandescent lamp and fluorescent lamp problems, its energy utilization rate higher than the fluorescent lamp, but also does not produce harmful substances to the environment, can be said to be the best choice for future lighting. At present, China is rapidly out of import and sale of incandescent lamps for general lighting. At the same time, LED lighting as the representative of energy-saving alternatives are gradually favored by consumers, such as retail, customer service centers and large factories. Compared with incandescent lamp, fluorescent lamp, LED lamp is solid light source, more energy saving, environmental protection, but the price is relatively high. With the cost of production and production process improvement, the cost of LED lamp is reduced by 20% to 30% per year. The fluorescent lamp has the advantages of mature technology, low energy consumption and long service life, and can be used as a transitional product of traditional energy-saving lamps and LED lamps. Learned. The optical efficiency of LED is about 8 times of incandescent lamp, fluorescent lamps of 2-4 times, with the development of science and technology, LED light effect will also continue to improve, but the price will be greatly reduced, plus LED has the advantage to replace the traditional lighting has become a trend. Comparison of energy saving between fluorescent tube and LED fluorescent tube:

LED fluorescent lamp fluorescent lamp to replace the advantages with the rapid development of LED lamp, LED has a low carbon emission reduction, environmental protection and energy saving, long life and other advantages, LED as a new light source and new lighting technology, under the strong support of governments, widely used in various lighting field. Some of the LED fluorescent tubes will not replace the fluorescent lamp is the inevitable trend. From the aspect of high luminous efficiency, luminous efficiency of fluorescent lamp is about 55-80 (lm/W Philips T8 fluorescent lamp luminous efficiency is 72lm/W), and the luminous efficiency of LED is over 100 lm/W, and the luminous efficiency of LED also increased year by year and month by month. The difference between the two is obvious. The efficiency of LED lamps and lanterns is high efficiency mainly refers to the effective light effect, because the fluorescent lamp is 360 degrees of light, and in the opposite direction of the light will be of no use. Therefore, fluorescent lamps usually use a white shade, can be a considerable part of the back light reflected back, in general, the fluorescent lamp efficiency is only about 70%. The LED fluorescent lamp is 120 degrees of light, so all the light is effective light. Although sometimes it will feel a narrow degree of light 120 degrees, but in most cases is enough. And the lighting angle can be adjusted as needed. LED lamp power supply high efficiency all lamps except incandescent lamps are required to have a special power supply, power supply efficiency will affect the efficiency of the entire lamp. Taking 36W T8 fluorescent lamp as an example. Its rated power output of 36W, but because access to the ballast, the measured input power is 42.4W, which is the core inductor loss 6.4W, the efficiency is reduced to 85%, most of the domestic iron inductance power in 10W above, the power factor is less than 0.512. The LED power supply is usually as high as 90%, a 18W LED fluorescent lamp as long as the input power of 20W. Power factor can also reach more than 0.9. Compared with the fluorescent lamp can save about half of the electricity, that is to say a 18 watt LED fluorescent lamp can replace a 36 watt fluorescent lamp.
