How to Connect Three 24V Lamps in Series Correctly?

Question

Hello, I have a problem, I`m a layman in this topic. I need to connect 3 lamps that are to be connected in series, but I have no idea about it and I would like to consult experts. Is this a series connection?

How to Connect Three 24V Lamps in Series Correctly?

This means connecting one lamp and two short circuits, keep trying. I suggest something like the above. You`re underestimating the level.

Neither this nor net.

Totally wrong. :cry:

For the first two, you shorted L and N, and how is that supposed to work?
When connecting three lamps (24 V), you need a 72 V power supply and where do you get it from?
Unless these are 6V bulbs and you WANT to connect them in series? And the power supply is 24 V.

And post #2 doesn`t mean anything to you? There you have the correct serial connection Although this is not entirely correct. Power supply +/- and lamp marking L/N.

Could someone draw me a similar diagram with the correct serial connection? If you think this jet is incorrect?

Thank you very much for your help, I would also like to ask whether this connection is also correct?

If these lamps are light bulbs or simple LEDs with a resistor, a series connection is allowed (pay attention to the polarization of the LEDs!).
Lamps with electronics inside should not be connected in series. One of the reasons is the negative dynamic resistance of systems with converters - the voltages will not be distributed evenly, something will get too little, and others will burn out.

At 24V, L and N are not marked, where do these markings in your drawings come from?

Serial connection.

My friend probably overestimated these LEDs, what about their polarization?

jarek_lnx · Answer

My answer did not take into account the post above because it was not there, I only wrote that a series connection is allowed, of course the polarization of the LEDs must match. I ask again what the L and N markings do there? at 24VDC

If I want to add one lamp to the series connection, can I do it this way?

kokapetyl · Answer

This is a mixed connection - in parallel (the first two) and the rest in series.

BarToOo1996 · Answer

so what should I do to ensure that the additional lamp is also in series? I should add that I cannot connect it in series with the last or first lamp?

kokapetyl · Answer

Turn it on like the others, in place of (the wire marked in green or yellow) You just need to know that the sum of the voltages of these bulbs must be equal to the supply voltage (this is, of course, when connected in series). When connected in parallel, the voltage of the bulb(s) must be equal to the supply voltage. I will also add that their power, when connected in series, should be the same for all bulbs. Because it may turn out that the supposedly strongest one will not light up at all, or only to a minimal extent.
