The scene can be terrifying and recognizable: you open your personal mailbox and, stuffed in an envelope, the company that provides electricity send it to us bill for their services. You take a deep breath, open the letter, and look in amazement at the price to pay. Consumption of electrical energy is a major headache for households. To minimize it, we teach you how to build an energy saving lamp

Fortunately, technology has enabled us to save on said consumption. More precisely, thanks to the arrival on the market of low consumption bulbs, known by the acronym CFL (Compact Fluorescent Lights), which replace the more expensive incandescent bulbs. Unfortunately, these bulbs will also stop emitting light one day, forcing us to buy another to replace it … Until today!

In the next article, we will take advantage of a energy saving bulb which has stopped working, to give it a second life as an energy-saving lamp. Eco-friendly DIY for the well-being of our pocket and for the design, for example, of the keys to designing your teleworking space

How To Build an Energy Saving Lamp | materials

We understand that if you’ve made it this far, you are a full-fledged handyman and you either understand what it is or want to reduce your monthly electric bill even a little. In this case, the first thing you need to know, besides how to build an energy saving lamp, are the materials what do you need.

Low consumption lamp

It doesn’t matter if you are familiar with circuits, capacitors, voltage or not, or know the symbol for the ohm (Ω), the unit that measures the electrical resistance according to the international system of units Standard. You just need to be aware of the risk of working and handling electronic devices, which there is, however small. Having said that, we are going with the necessary material to make your own energy saving lamp:

  • Bulb – A low-consumption bulb that does not work: it must be of the type socket E-27, which you surely have at home, because it is one of the most common.
  • Resistors – Keep in mind that all must be made of carbon, due to the lower sensitivity they present to current peaks.
    • To begin with, a 470Ω R1
    • Also resistors of the type R2 and R3, that is to say 1 MΩ.
    • Also stresses resistance 100 KΩ R4.

  • Capacitors
    • We will need a type C1 100nF and operating at 275V ~
    • Also a type C2 electrolytic capacitor at 47µF and 63V.
  • Bridge rectifier – A rectifier bridge BR1 type W10.
  • Diodes LED diodes white light from D1 to D6. More precisely, from 10 mm Ø and 10,000 mcd.
  • Glue – Fast-acting glue or glue.

How To Build an Energy Saving Lamp | Step by step

We already have the material, it’s time to learn how to build an energy saving lamp step by step. The ultimate goal will be to make (or recycle) a new lamp with 6 white light LEDs. The mechanics of the process are simple, you just have to pay attention to the handling of the circuits (they must always be disconnected from the electrical network) so that no unexpected short circuits occur.

  • Disassemble the bulb – The first step is to disassemble the exhausted bulb. To do this, we are going to remove it carefully so that the three fluorescent tubes it is made of do not break. Once outside, it is time to remove the electronic card from the bulb, also very gently.

  • Couple the diodes – Now is the time to hang (or hang, using the quick-acting tail) LED to resistor R4 and capacitor C2, just above the case which acts as a cover, taking advantage of the space left by the holes from which the original bulb comes.
  • Rest of the circuit – Once hooked up, it’s time to continue traveling the rest of the circuit. In other words, the couplings with the resistors R1, R2, R3, he capacitor C1 and the rectifier bridge BR1 that we will do inside, and with great care, of the bulb socket. Once this is done, the next step will be to join the two parts of the circuit that we have assembled, with the two red and black cables, so we will avoid polarity failures.

  • Cap housing – Finally, it suffices to set up the bulb socket housing with its cover and … assembly ready! As a last detail, you have to close the connection between the case and the cover with the quick-acting glue, so we will completely seal the final product. We already have our ultra low consumption house lamp!

Why build an energy efficient lamp

It is possible that you have already completed it and have not even wondered why build an energy saving lamp. the the reasons they are, eminently economicalyes, that is to say compared to energy saving. the advantage What is the LED technology is varied:

Build-the-low-energy-lamp-step by step

  • Low energy consumption – it consumes very little energy compared to other incandescent lamps, even low consumption bulbs, since its technology allows it to emit light at very low voltage.
  • Decorative function – In addition, nowadays they have also become fashionable for their decorative function in homes or premises: they dress your space very well and do not involve a drain on the final electricity bill.
  • Durability – But there is also another very important factor when it comes to manufacturing our energy saving lamp: durability. Not only because the simple act of recycling means that we should not consume other products, but also because of their high toxicity. The reason is that compact fluorescent bulbs (CFLs) contain Mercury inside, although in very small quantities.

In case you didn’t know, mercury is a very polluting heavy metal known to be “stuck” in the batteries that power our remote controls and other electronic devices. If we throw a product containing mercury in the standard trash, we put the planet in danger, because if it reaches the sea or a river, it could contaminate thousands of liters with very little substance.

Therefore, we must be very careful with the use (and abuse) of this type of energy saving bulbs. As we have seen in this article, we invited you to give them a second life. But if you are not trained to do this job, or if you just want to get rid of other bulbs, the best option will be to put them in a specific recycling bin, so as not to harm the environment.
