Bulb Ka Aavishkar Kisne Kiya Or Kab Kiya

Bulb to ham sabhi apne gharo me roshni ke liye ustemal karte hai. Kabhi hame ye nahi socha ki ye bhi bahut badi khoj hai. Or aaj lite bulb ki tini jarurt hai. Ki iske bina to har ghar roshni bina milega. Or inki mang badhti hi ja rahi hai. par pichle kuch time se bulb ki jagah CFL ne le liya hai. Kyonki ye bulb se kam lite leti hai. Or vah jyada roshni bhi deti hai. or ab to LED bulb jo bahut hi kam lite me bahut jyada roshni deti hai.

Bulb ka aavishkar Davy, Swann and Thomas Edison ne 1878 me kiya 14 October 1878 par Edison or unki tame ko pata chala ki ek Carbonated bamboo fiber 1200 se jyada hours chal sakta hai. Is aavishkar se pahle bahut kosis ki gayi. Jaise

1802 me Humphrey Davy  pahle lite ki roshni ka aavishkar kiya. Unhone kaha ki lite ke sath paryog kiya or ek Electric battery ka aavishkar kiya. Jab vah apne battery or carbon ka ek tukda karne ke liye taro se juda huaa. Carbon glowed Light ka  Construction kiya. Uska aavishkar electric arc Deepak ke roop me jana jata tha. Or yah jab roshni ka production kiya gaya. Yah hai. ki yah jyada time ke liye production or jyada Practical use ke liye bhi ujjval tha.

1850 me ek English physicist named Joseph Wilson Hans ek khali Glass bulb me attached carbonated paper fiber dwara ek light bulb banaya or 1860 tak vah kaam Prototype tha. Lekin ek acha Vacuum ki kami or light ki Adequate supply ek bulb jiska jivan bhar itni bhi roshni ki ek effect prodcer vichar kiya jana kam tha. lekin 1870 Decade me bdiya vacuum pump available ho gaya or swann light bulb par Experiment jari rakha. 1878 me Hans ek ka ilaz kiya suti dhaga bhi hai. Ki jaldi bulb black hone ki dikkat ko hata kar istemal kar ek jyada time tak tikau light bulb ka vikas kiya.

24 July 1874 ko ek Canadian ek Toronto Medical Electrician Henry Woodward ka name hai. or ek Associate Matthew Evans dwara patent dayar kiya gaya tha. We alag design or Nitrogen se bhara Glass cylinders me electrodes ke bich carbon rod ke design ke sath unke lamps ka Construction kiya Woodward or Evans unki deepak ka Commercialization karne ka paryas kiya lekin  rahe the. We last 1879 me Edison ke liye apne patent bech diya jiske bad unhone ek light bulb ka aavishkar kar diya jo ek bahut bada aavishkar tha.
