Quem nunca teve em casa uma lâmpada de filamento queimada? Esse tipo de lâmpada realmente queima com muita facilidade e sempre terminamos a jogando fora, porque realmente o resto não serve mais para nada. Bem, agora você poderá mudar sua opinião sobre isso. Que tal pegar aquela lâmpada queimada e fazer outra, só que de led?
Material necessário:
- lampada queimada
- 3 leds
- diodo 1N4007
- resistor de 10K 1/2W
- capacitor de 100uf
- ferro de solda e solda
- cola quente
- silicone (opcional)
Solte a parte de metal da lâmpada segurando firme e movendo para um lado e para o outro até ir soltando aos poucos. Com um pano e um alicate, quebre a ponta de vidro que fica para fora da lâmpada. Com um alicate de bico quebre a parte central de vidro da lâmpada. Retire todo vidro e deixe a parte central vazia.
Pegue os 3 leds e cole um no outro, com cola quente e solde eles em série deixando apenas duas pontas (positivo e neutro). Solde um fio na parte central da base da lâmpada e solde em seguida o resistor, o diodo e o lado positivo do led. A outra ponta do led solde na base da lâmpada (na parte lateral).
Eu coloquei um pouco de silicone dentro da lâmpada para que a luz ficasse mais difusa. Mas você pode lixar o os leds para isso ou usar uma lâmpada que o vidro seja branco.
Nas fotos você podem ver que usei uma base de lâmpada de fluorescente, mas dá pra usar uma base normal. Coloquei também o ferro de um clipe como apoio para fazer com que os leds fiquem exatamente no centro da lâmpada. Cole o vidro da lâmpada a base com cola quente (ou se preferir você pode usar uma fita adesiva dupla face.

Bom carnaval a todos.
Isso foi muito legal...agora vou revirar todo as lixeiras para procurar lâmpadas velhas e farei muitas iqual a essa assim poderei salvar o planeta terra.
ResponderExcluirObrigado,
Pina Paz
bacana seu projeto.. vc teria um circuito para ampliar para mais leds em uma mesma lampada...
ResponderExcluirgracias

Muito legal, já estou revivendo as antigas lámpadas que iam parar no lixo e assim poluindo o planeta. Você teria uma projeto para uma quantidade maior de leds tipo 20 por exemplo, e também se existe um projeto para lâmpada de freio e setas de carros e motos.
ResponderExcluirMuito obrigado. Muito legal mesmo!!!

muito legal mesmo!! Você teria o circuito para colocar mais lampadas? Abraços verdes!!
ResponderExcluirezrasantana@gmail.com
muito legal !
ResponderExcluirEsse projeto seria pra qual voltagem ?
220 OU 110 ?
arnaldo.motta@hotmail.com
Boas.
ResponderExcluirgostei imenso do projecto de renovar as lampadas fundidas..
tenho algumas questoes para lhe fazer, sera que podia entrar em contacto comigo??

fiquei na duvida no capacitor: nao tem MAIS NENHUM VALOR:TIPO 100/160 ou 180....?
ResponderExcluiragradeço desde ja e t+
esse projeto nao funciona para 220v pois o resistor torra.
ResponderExcluireu suspeito que o capacitor está invertido.
ResponderExcluirgostaria de saber se a lâmpada é para 220v. e se você tem outro projeto com mais leds. Obrigado
ResponderExcluirClaudiorsilva78@hotmail.com
oi esse projecto tb da pra lampada de 220v.?
ResponderExcluiragradeco resposta
luism.alves@hotmail.com
muito bom o seu video, ele ensina o que poucos tem o prazer de ensinar.
ResponderExcluirVc usou 2 lampadas? uma incandescente e uma fluorescente? e reaproveitou o circuito da lampada fluorescente?
ResponderExcluircomo fez?
legal amigo, agora minha casa vai ser iluminada a leds,,,leds tem 100.000hrs de vida então vou projetar varias para minha casa he he.
