Prinsip kerja lampu ini adalah pendaran dari lapisan bahan pospor di kaca lampu. Listrik yang di alirkan pada lampu membuat uap raksa didalam tabung tereksitasi dan melepaskan sinar UV gelombang pendek. Sinar UV tersebut kemudian menabrak lapisan pospor dan menyebabkan berpendar.
Dengan desain kerjanya yang unik, tidak semua lampu ini bisa di atur intensitasnya dengan dimmer. JIka dibutuhkan, anda bisa menggunakan CFL khusus yang dimmable. Tetapi sampai saat ini masih sangat sulit dicari di pasaran.
Lampu jenis ini menghasilkan cahaya dengan lebih efisien, sekitar 4 - 5 kali tinggkat terang yang di hasilkan oleh lampu dengan watt yang sama.
Karakter color temperature dari lampu ini bisa bermacam-macam, tergantung pada bentuk lapisan warna pada dinding tabung. Tiga jenis yang paling umum adalah Daylight untuk putih netral, Cool daylight untuk warna yang lebih dingin, dan Warm untuk warna menyerupai incandescent.

ReplyDeleteLED (light-emitting diode) lighting is totally different from traditional lighting, as the bulbs produce light by using semi-conductors. In a nutshell, it's digital light.

LED bulbs are additionally more ecologically friendly than different types of bulb, as they do not contain poisonous chemical compounds corresponding to mercury (which many other bulbs can) and are completely recyclable.
LED lights produce subsequent to no UV emissions and very little infrared light. This makes them the ideal choice for these with heightened sensitivity to UV rays or in areas containing materials the place UV exposure should be minimised, such as artwork exhibitions and museums, for example.
Thanks to rapidly creating know-how, LEDs are becoming much cheaper than they used to be. They're nonetheless more costly than other forms of light bulb, but in many ways their different benefits outweigh the fee factor.
