About filament type LED bulb

    LED filament is a new form of LED package, but also the most popular LED products. It can be used to produce similar to incandescent lamp shape filament type LED bulb, can easily achieve 360 ° luminescence.
    LED filament package is a kind of technology innovation, the ordinary LED lamp bead is a single voltage for the 3.0V chip is fixed on the plastic bracket, and then the dispensing package,  called the PLCC package. LED filament consists of multiple chips in series and is fixed on a glass substrate, and then complete the stamper package. LED filament has the characteristics of small current high voltage, effectively reduces the LED of fever and the cost of the drive, has the outstanding advantage.
    LED filament process is usually the 28 models for 1016 LED power chip 0.02W series is packaged in 38mm long, 1.5mm diameter glass substrate, and then die top fluorescent glue to achieve. LED filament with 10mA drive current, voltage 84V, power 0.84W, the flux of 100lm, light efficiency can reach 120lm/W, if assort or arrange in pairs or groups of red chip color index can reach more than 95, with excellent photoelectric performance.
    Using LED filament can produce a variety of small and medium power LED Bulb or candle light. Usually use four LED filament, two series and two parallel can design a 3.6W power LED bulb lamp or candle light, luminous flux is 330-360lm, can replace the 40W incandescent bulb.
