Keterangan :
Lampu TL (Tube Lamp) merupakan salah satu lampu penerangan
yang banyak digunakan baik di pabrik, gudang, bahkan di sekolah. Pada dasarnya
lampu TL ini berbentuk tabung dengan kawat pijar dikedua ujungnya (elektroda),
dan didalam tabung tersebut berisi
merkuri dan gas argon. Tabung lampu TL terbuat dari dari dari gelas dan warna
putih pada lampu TL itu berasal dari lapisan fosfor yang ada pada dinding
tabung lampu TL tersebut.

Cara kerja
dari lampu TL :
ketika sakelar yang dihubungkan sumber tegangan kita ON-kan maka
akan menuju Ballast. Fungsi dari Ballast sama seperti trafo dimana tegangan
sumber 220 volt akan di step up oleh Ballast hingga 400 volt yang kemudian
membuat Starter bekerja. Disini kita membutuhkan tegangan hingga 400 volt dan
starter (sebagai pemicu) agar elektroda yang ada pada ujung-ujung lampu TL,
jika tegangannya < 400 volt maka Starter tidak bisa bekerja. Setelah starter
mendapat tegangan sebesar 400 volt maka starter akan memicu/memanaskan
elektroda yang ada pada ujung-ujung lampu TL yang menyebabkan potensial + dan –
yang ada saling bertabrakan membuat pantulan cahaya dan membuat lampu TL berfungsi
atau menyala.
THE ADVANTAGES OF LED LIGHTING
BalasHapusLED (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.
They don't seem to be a new phenomenon; LEDs have been used in Christmas fairy lights, remote controls and digital devices for an extended time. More just lately they've begun to be more extensively available for lighting within the house, and have shortly develop into a vastly well-liked, energy efficient lighting solution. Listed below are some of the main advantages of utilizing LED lighting:
LED lights are much longer lasting than other varieties of light bulb, and the expected life of each bulb is around a hundred,000 hours. If your light was on for eight hours every day, the bulb would final somewhere within the area of 20 years. In consequence, the upkeep required to interchange the bulbs is much less too, which can be notably useful in a industrial or office environment.
LEDs convert approximately 80-90% of the energy they use into light making them among the many most energy environment friendly bulbs you possibly can buy. Traditional bulbs, on the other hand, can convert as little as 10-20% of the energy they use into light, which implies the lampu jalan remaining 80-90% is misplaced as heat. This implies while you choose LED bulbs you are actually paying to light your private home, slightly than for the lost energy when using other, less energy environment friendly types of light bulb.
Not like many energy saving light bulbs, with LED there's no need to attend for the bulbs to light up fully. They emit their full light straight away. Over time, the light they give off becomes slightly less vivid, but they don't usually burn out in the same approach that traditional bulbs can.
LED lighting only requires a low-voltage energy provide, so it may possibly easily be used in conjunction with photo voltaic energy.
They're more durable and hard-carrying too, and are climate and shock resistant. They can additionally stand up to extreme high and low temperatures far more efficiently than different bulbs, which makes them a unbelievable selection for out of doors lighting.
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.
