What causes a light bulb to go out?

Light bulbs give off light by pumping electric current through a thin tungsten filament. The filament heats and gives off light. Over time, the filament oxidizes and becomes more and more brittle, until it breaks apart and the bulb goes out.Click to see full answer. Herein, what would cause a light bulb to keep burning out? Too Much Heat For recessed or covered light fixtures, excess heat buildup can cause light bulbs to burn out. The easiest fix is to switch to lower wattage light bulbs. If this doesn’t work, you may need to switch to larger fixtures or use larger globes on covered light fixtures, which allows the heat to dissipate.Also Know, what happens when a bulb burns out? Every time a light bulb is turned on and off it heats and cools rapidly, which stresses the filament, causing it to become weaker and brittle. When the filament gets thin enough from repeated wear, it can snap, breaking the electrical current, and causing the bulb to burn out. why do LED light bulbs burn out? Instead of burning out suddenly like traditional bulbs, LEDs get gradually dimmer, as the individual light emitting diodes that make up the bulb fail one by one. Because this is such a small space, the heat builds to a pretty high temperature and raises the temperature of the air trapped inside the bulb.How do you make a light bulb burn out?You can simply cover the light bulb with aluminum foil in a few layers, so that it cannot radiatively loose heat fast enough, the filament will burn in two. Some kitchen locations, the bulb will get covered with particulates from cooking, and this will shorten the filament life too.
