LED lighting has been a leap in the recent developments, LED as light green cleaning is widely recognized. LED light, long life, energy saving, easy application, low cost, and thus in the family will receive a flood of illumination applications, OSRAM optical semiconductor company survey in 2008, the global annual home lighting lamp shipments of approximately 50 billion.
LED light source technology matures, lumens per watt LED grow rapidly, prompting its diminishing prices. In 1WLED light, for example, in 2008 the price of spring is the spring of 2006 the price of one-third of the spring of 2009 will be reduced to one quarter of 2006.
LED green lighting mass market and a steady growth in demand will be for several years following the IC industry VCD, DVD, mobile phones, MP3 after the consumer electronics market super tsunami!
LED lamps of high energy saving, long life and interests of environmental protection superiority universally recognized.
LED High energy: DC drive, ultra-low power consumption (0.03 W -1 watt single tube) electro-optical power conversion close to 100%, the same lighting effects than traditional energy sources more than 80%.
Long-life LED: LED light source is called longevity lamps. Solid cold light source, epoxy resin, light body and no loose parts, there is no filament light easy to burn, heat deposition, the light fades fast and other shortcomings, the service life of up to 50,000 to 100,000 hours, longer life than conventional light sources 10 times.
Lee Green LED: LED is a green light, better environmental benefits. No ultraviolet and infrared spectra, 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.
LED light work characteristics:
VF lighting LED light source voltages are very low, generally VF = 2.75-3.8V, IF at 15-1400mA; therefore LED driver IC output voltage is VFXN or VFX1, IF constant in the 15-1400mA.LED use LED lamps Light has a small power (IF = 15-20mA) and high power (IF> 200mA)) two kinds, usually used to make low-power LED LED fluorescent lamps, decorative lights, grille; families used to make high-power LED lights, radio lights, underwater lights, wall lights, street lamps, tunnel lights, car lights work. Power LED light source is a low voltage, high current-driven device, the luminous intensity of the current flowing through the LED determines, over-current will cause the LED light attenuation, the current is too weak affect LED luminous intensity, therefore, LED's 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, to reflect the characteristics of energy saving and long life, choose a good LED driver IC is essential, not a good match driver IC, LED lighting advantage can not be reflected.
