Incandescent and LED lighting

BAS. It is not a case of names that I do not like. It is names that are so misleading as to the function of the item as to be hazardous.

Ban All Sheds is never going to recognise the hazards created by the mis-naming of electronic / electrical equipment.

Imagine that there were these two types of device sold, and that they were all consistently and correctly called:

• Constant Voltage LED Power Supply
• Constant Current LED Power Supply

Would you object to either of those names? If so, which one, and why?

And whether you would object or not, can you posit any hazards which would arise from them being called that?

Which part here is the driver?

The battery drives current through the LED element and the resistor controls the current I = (Vb-Vf)/R

• Constant Voltage LED Lamp Power Supply
• Constant Current LED Element Driver

And whether you would object or not, can you posit any hazards which would arise from them being called that?

A 700mA LED Power Supply (*) was used to supply power to several 12 volt DC LED lamps ( items with a driver and LED elements ). The lamps were destroyed.

Before being installed the lamps were tested by connecting them to a 12 volt DC supply ( constant ouput voltage, output current determined by the load ).
The lamps worked.

They were destroyed when connected to the 700mA LED Power Supply because they were not taking 700mA from the supply so the 700mA LED Power Supply increased its output voltage in an attempt to drive 700 mA through the lamps. This resulted in the lamps being supplied with about 28 volts.

(*) 700mA LED Power Supply should have been labelled as an 700mA LED Driver

So what everybody else calls a battery, are you now calling it a driver, because it drives current through the LED element?

I can see that some people might be upset by such renaming.

Jolly good.

You've tried this sort of thing before, and it has never worked in the past, I'm surprised to see that you still think it might.

Instead of posting a response which does not answer the question, please answer it.

And as for the damage you described, this seems to be going the same way that the discussions we had about electronic transformers went. In that case, over and over again you kept on talking about problems which could, and did, arise from the inappropriate use of one, but you never, ever, not even once, and no matter how often I asked, even tried to explain the mechanism whereby people used electronic transformers inappropriately because of the name.

Are we going to have the same thing happen here?

Or are you going to explain how the damage you described occurred because the 700mA LED Power Supply was not called a 700mA LED Driver?

An electricician in coastal town was asked to sort out a set of 12 volt tension wire lamps that no longer worked. Finding no voltage at the output of the transformer he replaced that transformer with a new modern more compact transformer.

Lights worked, until there were complaints about interference to marine radio services. The source was tracked to the shop and the EMI from the new modern transformer was identified as the source.

Did the electrician know the difference between a transformer and a transformer or was he mislead by a sales man who said that modern was always better.

There hundreds of cases of EMI from transformers disrupting radio services.

OK - I think we can all now see quite clearly that you have absolutely zero intention of ever explaining why problems happen SIMPLY BECAUSE OF THE NAME OF THE DEVICE.

You don't like the names of some of them, and are obsessed with using this site as a way to vent your displeasure, but your refusal to ever even try to explain why the name of the device is what causes problems shows that it absolutely does not.

You have not a scrap of justification for your campaign, it is nothing more than a senseless dislike of the names given to some things.

BAS ...

What technical knowledge, if any, do you have ?

Have you ever worked in any area of electronics where basic technical knowledge was necessary to perform your duties in an efficient and safe way. ?,

it is nothing more than a senseless dislike of the names given to some things.

And your campaign is ( or at least appears to be ) one that is telling readers that all items called "transformer" are interchangable.

What relevance does that have to your refusal to answer any of the questions I have asked you?
