The correct choice of LED driver IC is essential to reflect the characteristics of energy saving and long life of the LED lights In the field of LED lighting. The advantage of LED lighting can not be reflected without a good driver IC matched,.
LED lighting has been a leap in the recent developments, LED as the green and cleaning light is widely recognized. LED light source is known as long life, energy saving, easy application, low cost, and thus it will receive a flood of applications in home lighting, OSRAM optical semiconductor company surveyed that the global annual shipments of the home lighting lamp was about 50 billion in 2008,.
LED light source technology matures, the lumens per watt LED grow rapidly, prompting its diminishing prices. Taking the 1WLED light, for example, the price in the spring of 2008 is one-third of the price of the spring of 2006, the spring of 2009 has be reduced to one quarter of 2006.
The mass market and a steady growth in demand of the LED green lighting for several years will be super tsunami of the IC industry following VCD, DVD, mobile phones, MP3 on the consumer electronics market!
The superiority of high energy saving, long life and good for environmental protection of the LED lamps is being universally recognized.
1.LED High energy: DC drive, ultra-low power consumption (single tube is 0.03 ~ 1W) the electro-optical power conversion is close to 30%, the same lighting effects is 10% more than that of the traditional energy sources.
2.LED Long life: LED light source is called as longevity lamps. It is the solid cold light source, epoxy resin, there is nearly no loose parts in the light body, and there is no filament that is easy to burn, heat deposition, the fast light fades and other shortcomings, the service life is up to 50,000 hours, the life is 5 times longer than that of the conventional light sources.
3.LED is good for environmental protection: LED is a green light, the environmental benefits is better. The spectra contains no ultraviolet and infrared, low in calories and no flicker, no radiation, and recyclable waste, no pollution, no mercury elements, cold light source, safe touch, typical of the green lighting.
The work characteristics of the LED light
The VF used for lighting of the LED lighting source is of low voltages, which is normally 2.75 ~ 3.8V, IF is generally 15 ~ 1,400 mA. Therefore, the output voltage of the LED driver IC is VFxN or VFx1, IF keep the constant that is at 15 ~ 1,400 mA. There are two kinds of power that are the small power (IF is 15 ~ 20mA) and high power (IF is greater than 200mA) used for the LED light source. The Small power LED is mostly used to produce LED tube light, decorative lights, grille light. The big Power LED is used for household lighting, LED flood light, underwater lights, wall lights, street lamps, tunnel lights, car lights. Power of the LED light source is the device that is suitable for the low voltage, high current drive, the luminous intensity is determined by the current flowing through the LED. the LED light attenuation is caused by the General Assembly Current, the too small current will affect LED luminous intensity. Therefore, LED driver needs to provide constant current power to ensure the safety of high power LED, and to achieve the desired luminous intensity. In the field of LED lighting, the correct choice of LED driver IC is essential to reflect the characteristics of energy saving and long life of LED lights,. Not a good driver IC matched, LED lighting advantage can not be reflected.
Nowadays,the LED flood light and LED tube light is most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood light is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood light so that fully guaranteed stabe and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood light and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, thats why the LED light is Known as energy-saving and environmental protection ,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
