Something About Filament

LED Technology with Filament Bulbs Like led filament bulb, led Edison bulb, vintage led bulb, Edison light bulb, led filament bulb factory.

LED filament, a new form of LED package, is nowadays the most popular LED products. It can be produced in incandescent lamp shape, you can easily achieve 360-degree omnidirectional light.

LED-filament package is a technological innovation, ordinary LED lamp beads is a single voltage of 3.0V chip fixed in the plastic bracket cup, and then dispensing package, the PLCC package. The filament is a series of multiple chips fixed on the glass substrate (COG, normally ceramic or sapphire substrate), and then die to complete the package. Filament features with small current high voltage characteristics, effectively reducing the LED heat and drive costs, with outstanding advantages. In this case, LED filament technology is usually 28pcs 0.02W 1016 LED chip in series packaged in a long 38mm, 1.5mm diameter glass substrate, and then to the top of the fluorescent adhesive to achieve. LED-filament with 10mA current drive, voltage of 84V, power of 0.84W, luminous flux of 100lm, luminous efficiency can reach 120 lm/watt, if with the red chip, colour version catalogue can spread 95 or more, with outstanding photoelectric properties. Now, we also have 28mm, 68mm, long led filaments and even soft spiral led filaments.

LED Filament

The use of filament can produce a variety of small and medium power LED bulbs. Usually using four filaments, the second string and can design a power of 3.5W LED bulb or candle lights, with 330-360lm of luminous flux, can replace the 40W incandescent bulbs. In this case, LED Filament bulb factory can use existing technology and production lines LED bulb lamp, the original use of incandescent glass stent design filament connection; the use of incandescent high transmittance of special glass and automatic glass blowing bubble Production technology, design and production of incandescent ball-like bubble cover, which can produce cost-effective filament bulb lights. In this case, all Edison bulbs can be replaced by filament bulbs. Now is becoming more and more popular Like led filament bulb, led Edison bulb, vintage led bulb, Edison light bulb, led filament bulb factory.
