LED lighting knowledge

LED light source is called longevity lamp. Solid-state light, epoxy resin packaging, light body and no loose parts, there is no filament burnability, thermal deposition, fast decay etc..

The technology of LED light source is mature day by day, the luminous lumen per watt is increasing rapidly, which makes it decrease year by year. LED green lighting market and the continued growth of a large number of years of steady demand will be integrated circuit industry following the VCD, DVD, mobile phones, MP3 consumer electronics market after the tsunami!

LED lamps of high energy saving, long life, environmental benefits of superior performance has been widely recognized.

LED high energy saving: DC drive, ultra low power (0.03 watts -1 watts) power conversion is close to 100%, the same lighting effect than traditional light source energy saving more than 80%.

LED long life: LED light source is called longevity lamp. Solid-state light, epoxy resin packaging, light body and no loose parts, there is no filament burnability, thermal deposition, fast decay etc..

LED life: service life of up to 50 thousand to 100 thousand hours, longer than the traditional light source life more than 10 times.

LED lighting knowledge

LED Li environmental protection: LED is a kind of green light source, environmental protection is better. No ultraviolet and infrared spectrum, low heat and no stroboscopic, no radiation, no pollution and waste Recyclable, no mercury, cold light, safe touch, which belongs to the typical green lighting source.

LED light source characteristics of the LED lighting source VF voltage is very low, general VF=2.75-3.8V, IF in the 15-1400mA; therefore, the output voltage of the LED drive IC is VFXN or VFX1, IF constant current in 15-1400mA.

LED light LED lamp with low power (IF=15-20mA) and high power (IF 200mA) ") two, small power LED for LED fluorescent lamp, decorative lamp, grille lamp; high power LED used for family lights, spotlights, underwater lamp, wall lamp, street lamp, tunnel lamp, car work lights.

Power LED light source device is low voltage and high current drive, the luminescence intensity is determined by the current flowing through the size of LED, the current is too strong will cause LED light attenuation, weak current will affect the luminescence intensity of LED, therefore, LED driven by the need to provide a constant current power supply, to ensure the safety of large power LED use, and achieve the ideal 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, there is no good driver IC match, LED lighting can not reflect the advantages of.
