Hi there, can anybody help me identify the red square component with three small wires connected to three main wires in lighting fixture? Thank you.

 

Almost looks like a trigger transformer in a photo flash.

Lamp operating voltage?

Current or wattage?

Bulb type?

ak

 

Could be a capacitor or choke used for noise suppression?

Thank you AK. I am going to check the following when I get to work tonight:
1. Lamp Operating Voltage
2. Current or Wattage
3. Bulb Type

The lamp is attached to Animation fixture in our attraction, when the target is hit, the lamp is suppose to lit but it stops since last month and when we open the fixture, the red wire is burnt and detached..

 

Could be a capacitor or choke used for noise suppression?

Thank you Homebrew1964. It is connected to our attraction. The red wire was burnt and detached from the fixture that is why the lamp is no longer lighting up when the target is hit, I am wondering if the red square thing is also burnt

 

Hi D,
It looks like a capacitor to me.

The red wire looks quite substantial, so a fair bit of current. This wire burnt off, but didn't trigger the fuse, so to me it looks like it wasn't attached properly in the first place. If you can re attach it properly, then try again.
Perhaps get an electrician, for safety.

If the red wire that looks burned off was connected to that three leaded block then it could be complicated. The picture in the photo in post#1 does notprovide any hint as to where that burned off red wire was connected to.
AND it is not the red wire from that small block device. AND what sort of device doesthat group of wires connect to??
SOME Built in light fixtures used a flourescent tube with an external ballast module. They had a multi-pin socket.

SINCE WE HAVE NO INFORMATION AT ALL as to what type the light emitting device is, you will only get guesses.
There are at leastthree different types oflight device. let us know what kind it is.

 

Hi everyone, these are the pictures of the lamp, it doesn't have specs written though

Hi D,
Amateur reply!
To me it looks like one of the pins is a little tarnished, so maybe arcing?
also perhaps a need for a capacitor, so perhaps that broken capacitor.

Also, it looks high voltage, so be careful.

Thanks C, I'm trying to get the value of the red square(??) to replace it

 

The red rectangle has a coil inside.. so it is not a capacitor.. but I cannot see any labels to buy a replacement

 

Hello,

The light is a xenon flasher.
The red block is the ignition transformer.

Thanks Bertus, is there a way to test using DMM if the ignition transformer is okay?

 

Hello,

The transformer consists of two coils.
One is the driver side, wich has a low resistance.
The other is the fire side, wich has a high resistance.
Take a look at the schematic on this page:
https://makingcircuits.com/blog/simple-xenon-tube-stroboscope-circuit/amp/
Discharging the capacitor on the driver side will give a very high voltage peak on the fire side.

Hi everyone, these are the pictures of the lamp, it doesn't have specs written though

What I see in those (very good) photos cerainly looks loke a xenon FLASH TUBE. My ome experience with making one stay lighted resulted in it exploding (bursting) after a few seconds.
So the small block with three wires would be the trigger transformer.
So Bertus is totally correct. BERTUS IS TOTALLY CORRECT!!!!
The trigger transformer would be driven by a short pulse from a charged capacitor.
So the assembly IS NOT A LIGHT FIXTURE!!! It IS some sort of flash device. I have seen hazard warning lights that were similar. They were above the doors to a crash-sled installation to warn that it was armed and ready to launch, so that people must not enter thru that door.

 

Hello,

My ome experience with making one stay lighted resulted in it exploding (bursting) after a few seconds.

In the datasheet the repetition rate will be given.
Do not exceed the maximum repetition rate, it will shorten the tube light.

See this thread for more info:

Bertus

 

In addition to the flash rate, do notexceed the flash capacitor value, or the voltage limit. OR the flash power. Once3 a flash tube is triggered it CAN carry a lot more current that iit will surviive carrying. That is, it does not have an internal current limiting ability.
So now that you (the Thread Starter) know that the thing is not a light fixturem and what it actually is, do you have an interest in learning how to make it flash??

 

Hi everyone, these are the pictures of the lamp,

Hey, post #2. Way to bury the lead.

Note that the trigger transformer is actually an auto-transformer; that's why it has only three leads. For small flash units, the input voltage is usually over 100 V, while the output voltage is in the 4 kV range. Larger professiional units probably have higher numbers. Digi-Key has some, but too small for your unit.

One more time! I know this is boring, but calling a flash device a "light fixture" , when it idoes not match most "light fixtures" is confusing. At least I found it confusing.
