The light does not light up after the capacitor is stopped

Repairing led shop lights.

I saw a You Tube on repairing these lights by simply replacing the capacitor. My problem is getting to the capacitor without tearing up the fixture. Any help in disassembly of these light would sure put me on the road to repairing the thing. They are cheap enough to just buy a new one and as a matter of fact the last 2 I got with earnings I got

Powering the electronics in the smart switch from the 2 hot wires will draw current through the light bulbs, making them either flash or light up (maybe except for some incandescent ones, but I can''t rely on the light bulb type in any way; all usual types ranging from 1W to 100W, 110/230VAC should be considered).

Refrigerator Compressor Not Running

Connect the capacitor to the leads for a few seconds. Then swap the leads to the opposite terminals. If the capacitor is at least storing some charge, you should get a short beep. This will not tell you if the capacitance is correct, only that the capacitor will store charge.

Microwave Just Stopped

The light does not work, the panel doesn''t light up. From all appearances it is dead. I tried resetting the breaker at the panel box but nothing changed. Is there something I can reset on/in

Ceiling Fan Not Spinning Normally, Replaced

I am not sure if newer ceiling fans simply are not as loud hummers as they used to be. You can kind of see it start to snail-crawl when you first turn it on. No, it does not stay spinning if I give it a spin, but; Yes, it does

6 FAQs about [The light does not light up after the capacitor is stopped]

What happens when a capacitor is powering a led?

When the capacitor is powering the LED, the circuit is an RC circuit with an exponentially decaying voltage. The LED is only going to stay lit for as long as the voltage remains above the forward drop voltage.

Can a capacitor cause a led to fade?

Capacitors don't magically discharge, when they are charged they act like small fast-depleting batteries. You could discharge your capacitor by shorting it with a small value resistor (not with a wire, as that could cause it to be damaged). Then the led would start fading again. Why doesn't your LED light up again when you disconnect the battery?

Why does my LED light go off slowly?

If you are somehow expecting the LED to go off slowly because the capacitor charges up and 'takes away' the voltage from the LED, having the C parallel to the LED won't work - you'd have to have them in series. You'll find though the LED won't light up at all, or only blink very briefly as explained below. You could try a supercap (> 1F).

How do I know if a capacitor can power a led?

Since capacitor values are not very precise, and the LED doesn't produce much light at low currents, we can estimate the amount of time the capacitor can power the LED as the time constant of the RC circuit. It's not the exact time, but it will give you a ballpark estimate of the decay time for the fade out.

What happens when the capacitor is charged?

What happen to the capacitor is that it store the electricity, not consume, until it is charged up to 3V in the opposite direction to the batteries, meaning that the longer tail of the capacitor becomes 3V. So then the voltage drop between the LED gradually (the speed depends on the capacitance of the capacitor) becomes 0V and the LED.

What type of capacitor blew up a work light?

So, the capacitor of the work light that blew up is a 25V 220uF electrolytic capacitor. I do have a few ones in storage with the same spec and material, but the size of it is not the same.
