What are LED Filament Bulbs?

Filament LED bulbs usually looks like a traditional glass light bulbs. The yellow strip that provides the light, was created to look like the filament of an incandescent light bulb, hence the term LED filament bulb. The original LED filament bulb was intended to mimic the appearance of the original Edison light bulb, you can see in the image how the two compare.

How Do LED Filament Bulbs Work?

The LED filament is composed of a metal strip with series of LEDs aligned along it. A transparent substrate, usually made from glass or sapphire materials is used to cover the LED’s. This transparency allows the emitted light to disperse evenly and uniformly without any interference or light loss.

The LED’s on the filament strip actually emit a blue coloured light so an even coating of phosphor in a silicone resin binder material is placed over the glass to convert the blue light generated by the LEDs into a more preferable colour. Different phosphor colours can be used to change the colour of the light. For example, the more yellow the phosphor, the more yellow and warm the light becomes. This is how the the different colour temperatures are created.

The major benefit of this design is the ease with which near full ‘global’ illumination can be obtained from arrays of filaments. Another positive benefit is better heat dissipation over traditional designs, due to the LED’s being more spread out, rather than densely concentrated. This in turn can lead to increased lifespan.

Main Features of Chenxin Filament Range.

360 Degree Beam Angle: The clear glass cover and long LED filament make it possible for this bulb to provide a wide 360 coverage of warm light.

Matching Dimensions: The LED filament bulbs are designed to the same dimensions as traditional filament bulb, so replacing they couldn’t be easier!

LED Efficiency: They may look like retro style filament bulbs but they are packed with the latest LED technology and offer more than 100lm per Watt in energy efficiency.

Standard and Dimmable: Our standard filament range are all flicker free and we also supply select lines in fully dimmable versions so you can turn the brightness down and turn the atmosphere up!

Style and Shapes: the new filament range comes in a wide range of shapes and fittings, so you can find the style that’s right for you. Bulbs are available in: Candle, candle with tail, Large G95 Globe shapes.
