4W LED Filament Light With Ligh Lumen

LED filament bulb will replace most of the traditional incandescent lamp, with the growing of LED lighting ,LED filament will become the new darling of the market.  Nowadays they are into LED bulb market ,and into our life in domestic and business.

LED to tungsten thoroughly solved the problems of the LED ball steep light fever, so the current surge in market demand, especially the European and American markets. LED to tungsten development now encountered problem is the small size requirements drive scheme (due to the shape), the power of the duty ratio based on  development size smaller than the one yuan coin, now is in short supply.

With the continuous development of led technology, the led lighting source as possible, because the light source in lighting lamps and lanterns has strict requirements on color rendering index CRI, and the white led technology in the aspects of color is not very mature, make it become the main obstacle of the led as lighting source.


White light for composite light through a prism, very easy to break out it contains different colors of light.The chromatographic comprehensive LED is a kind of light source, the characteristics of the wide color gamut of LED lighting products, which lay a theoretical foundation for high color rendering.


Light is a kind of wave particle two-phase material, the material includes wave characteristics include the characteristics of the particles, the compound characteristics make it strong, so from the essence and characteristics of the LED light, LED, as a high quality lighting source possible.


Current white LED technology, mainly adopts blue chip phosphor powder coating process, the technology developed by day and the company, from a certain extent with fluorescent tube light-emitting principle of this technology due to the lack of the composition of red light and green light, to make it on there is a congenital defect of insufficient color rendering index, to make up for the defects at present, phosphor technology has become a main direction in the industry.


Blue chip coated with phosphor powder manufacturing white light, this technique can be produced on the principle of white light with better effect, but in the use process due to the weak adaptability to the environment, cause the difference between theory and actual product, the difference is largely because of the LED heat accumulated temperature on the influence of the phosphor powder.
