I broke an LED; will connecting the one wire leading in to the wire leading out break the device? Answered

I have a broken LED. Will connecting the wire leading into the LED to the wire leading out of that one LED break the device? I don't have solder so my plan was to twist together the stripped wires and wrap in electrical tape.

Would powering on the device cause any sparks? The LED is part of a group of LEDs in a ring around the cone of a hair dryer. There are wires leading up to this ring-shaped circuit board with six leads and a resistor. Would directly connecting the two wires leading up to this ring-shaped board break anything or potentially be hazardous if operating the hair dryer?

Now that I think about it, the electrical tape would not be a good idea as it would probably melt

When you look at the pic the red leds are just plastic covers, probably hollow.

I would like to know if I'm correct ! Please tell me if you still have it Guyersky...

My grand kids call me Popsky because of my homeland..

The LED has two very short leads
soldered into the bottom of the board. These are standard LEDs. I'm not
sure what you mean by "just plastic covers."

Here is what I believe China did from examination of your photo.

The left is a standard solid through hole RED LED while the right is a Faux plastic covered SMD ( like in your phone led ) made to resemble the one on the left....

I would wager they had plenty of those circular Printed Circuit Boards left over and needed to match the advertising photos and ran out of the throughole LED units.

I don't understand. How can you break something that as already been broken? :)

Are you concerned about the other LED's

The main hair dryer component should still work. I was concerned due to how this thing is wired, that turning on the hair dryer with the shattered LED could cause a spark or just kill the hair dryer.

I don't have soldering
equipment here so I was looking for a solder-free fix that would allow
continued use of the hair dryer.

I have very limited knowledge of
electronics, but I was able to get the gist of the discussion. It
doesn't look like this is fixable without solder equipment.

Thank you for all your help.

A very careful look at the excellent pictures of your ring looks very strange !

The missing "led" wire is not like any real LED wire I have ever seen in my 40 years of engineering more like the wire from an wired light made to look like a through hole LED...

I have the suspicion this is a China mod to an old ring look like an LED ring. Expanding the picture and .... Aha .. I see what looks like a tiny SMD LEDs still attached to the red wire. . . The 4K resistor also makes sense.

You could replace the SMD LED with a true through hole LED but find a friend that can solder it for you.

On the other hand you could just cut the ring off and bend back each lead then tape

them individually in a cool safe spot. The ring is fairly sure to be just for looks anyway.

Also, if you find someone to do the soldering, make sure they understand "polarity"

+1 Excellent point.

LED ( Light Emitting Diodes ) are special DIODES that can only produce light when placed in the correct direction for electric current flow.

Guy has used the Tags Anode, Cathode suggesting a good understanding that there is a polar difference...

If you blow the photo up to +500, the shoulder of the base is apparent. I also initially thought it was a wired SMD with a cap. One leg (-) is pulled out completely so there is nothing to “twist together” (-max- noted this). It is likely a “Basic Red LED”.

+1 on decorative and soldering to fix or cut and tape..

Yeah, I'm going to guess no, the entire LED housing broke away, leaving only the anode and maybe part of a bond wire, the LED junction itself is probably embedded in the red clear plastic, lost forever. With LEDs costing literally pennies, I see no reason to just replace it entirely. A soldering iron would be required however.
