LED filament bulbs are more expensive than standard LED bulbs and generally have a shorter lifetime (around 15,000 hours). Nevertheless, it can be said that it is the right choice for chandeliers due to their classic and stylish appearance.
Since LED light bulbs are more efficient light sources than previously used halogen and compact fluorescent lamps, they are frequently used in home lighting.
Regular LED bulbs that we are familiar to see in recent years are not made of glass like other bulbs. For this reason, it has an extremely durable structure.
LED bulbs contain a large number of LEDs. LEDs are lined up on the aluminum circuit board inside the bulb. Directional, bright and sharp light emanating from LEDs is controlled with a white cover called diffuser. The diffuser helps to distribute the light more homogeneously and smoothly. If there were no diffuser, the light would be concentrated in a single point and would not be sufficiently dispersed throughout the room and bright light would disturb your eyes.
In LED bulbs, there is an LED driver in the plastic body between the diffuser cover and the socket that provides the appropriate voltage and current to drive the LEDs. The inner part of the body is covered with aluminum, so it also undertakes the task of dissipating the heat generated on the LEDs. If you touch the body after the LED bulb has been running for a while, you can feel that this part is getting hot.
In LED filament bulbs, instead of using a surface-mounted LED array, filament wires formed by combining microscopic LEDs are used. There are dozens of LED chips on each filament wire. There is a yellow phosphor coating on the LED chips. This is the reason why the wires inside the bulb appear yellow. The phosphor coating is responsible for converting the light produced by the LED chip into white or yellow light.
Since LED filament bulbs can emit light at an angle of 360 degrees, a diffuser is not needed. Transparent glass is used to protect the filament wires. Therefore, it is more fragile than regular LED bulbs.
LED filament bulbs do not have a complex driver circuit. It is sufficient to use a simple diode and capacitor instead. Because the voltage (DC) of the LED array on the filament wire is the same as the mains voltage (AC). LED filament bulbs have a compact appearance due to their simple structure.
LED filament bulbs are more expensive than standard LED bulbs and generally have a shorter lifetime (around 15,000 hours). Nevertheless, it can be said that it is the right choice for chandeliers due to their classic and stylish appearance.
