We make a flashlight from an idle bulb

In this review, we present to your attention an interesting idea for making a flashlight from a broken fluorescent light bulb.

Let's start by watching the author’s video

[media = https: //www.youtube.com/watch? v = CTlWpgxkksM]


What do we need:
- electric lighter for gas stoves;
- idle fluorescent lamp;
- screwdriver;
- pliers;
- glue gun;
- a hacksaw for metal.


According to the author, to get a better result, you should use a weak lamp. Let's get started.



The first step is to disassemble the fluorescent lamp. To do this, take a flat screwdriver and just pry the bottom plastic part. We go around in a circle so that the plastic part is separated by a click.


Next we need to remove the board. Note that in most cases, fluorescent lamps fail precisely because of these boards. To remove the board, it is enough to unscrew the four wires that hold it.


Next, take a hacksaw for metal and cut off the base. The cut off base and board we will no longer need.


Let's move on to the lighter. Remove its upper part and cut it off.



Now two wires that come out of the lighter need to be connected to a fluorescent lamp. Two pairs of wires will stick out of it, so the wires that are nearby you just need to twist together.

We pass the lighter through the plastic ring in which there was once a cap. We connect the wires.

Glue the lighter with hot glue for greater stability.


We snap the fluorescent lamp.

Flashlight is ready.

And also at high frequencies.

In my opinion, everyone forgot that all of the electronics we use is used, including in lamps, of Chinese manufacture, and these damn Chinese do everything so neatly that there is no margin of safety so that the lamp can burn out because the kettle turned off

Valery,
Rosin, which is found in most common fluxes, has the bad feature of increasing its electrical conductivity over time, possibly due to the penetration of water into microcracks. Especially bad traces of it affect high-resistance and high-voltage circuits.

How does flux affect this? It does not apply to the entire fee. And if, "parallel to it" there is solder, then it will not bother anyone))) ... Not?

Of course, an increase in voltage can be the reason, as listed above, as well as, for example, an increase in current due to not washed out flux.

Not ... here I really, really do not argue. Well I said that the amateur in this ...
It’s just that, in my opinion, when jumping on a cirque and static resistance, the current should change in this section of the circuit ... Here are the missing milliamps for burning the resistor ... Correct, if not ...
.. That is, I assume that it is an unstable network that can be the main reason for the failure of electronic ballasts.

acute Valery, do not argue with the academician.

From anywhere: from an increase in ambient temperature, from a change in the parameters of the tube.

Ivan_Pokhmelev,
So where is the excess?

The voltage was normal. In that circuit, since the resistor was, on the one hand, a limiter of the pulse current through the capacitor, and, on the other, a protection element, its power was almost at the limit so that it would simply burn out if the current was exceeded.

Again .... but wasn’t it a fault in jumping? ... Was it in the city? In a stable network?

You are not quite right, it happens and electronic ballasts fail. For example, a small SMD resistor burned out in it, which is simultaneously a kind of fuse.

You can ignite a burned-out lamp with a piezoelectric element

And yet .. For many times I read about the fact that it is the electronic ballasts that burn out in the lamps, and not the spiral ... Where do you live?)))) In the USSR?))))) Electronic ballasts are only afraid of unstable voltage. Only during horse racing it burns down ...
For a long time "I talk with the so-called" energy-saving lamps ".. I bought forty somehow. Then I bought three to five more .... For many years, almost everything burned out safely and I switched to diode .... but None of the electronic ballasts did not fail !!! They burned ONLY THE SPIRITS. Moreover, after devolving, I ran into very cheap lamps - the "halves", without the base and electronic ballasts, were just the tubes themselves. I added them to the old electronic ballasts from my burned-out ones. It turned out ... not quite aesthetically pleasing, so they shone in the basement, garage, street "balls" ... And some electronic balloons "survived" three flasks !!!
After reading this article, I asked the knowledgeable people the same answer: the electronic ballast does not burn out !!! It crashes only when the voltage jump! But it is now stable !!! At least twenty years past! )))) Gone are the days when a neighbor could cut welding with impunity ... And even in the village I have not seen transformer welds for a long time already - it makes sense if you can buy an inverter for half a salary and not tremble, waiting for energy monitoring to visit .. ..

In order for the lamp to shine continuously, you need to apply a voltage of 160-260V to it constantly. The lighter gives a pulse voltage only when the button is acted upon - by pressing / releasing it, the piezoelectric element is affected.This mode of using the flashlight is not convenient (remember the "bug" - the flashlight with the "dynamics" and the lever for pressing?). IMHO, it's easier and cheaper to buy a Chinese LED flashlight ...
