How does excessive heat contribute to the failure of bulbs?

Excessive heat significantly contributes to the failure of bulbs.

When bulbs are exposed to high temperatures, it accelerates the degradation process, leading to a shorter lifespan. Heat causes the filament inside the bulb to become more fragile, reducing its ability to withstand electrical current. This can result in the filament breaking or weakening, causing the bulb to fail.

In addition, excessive heat can cause the components of the bulb, such as the base and wiring, to expand and contract more rapidly than they are designed to. This repeated thermal stress can damage these components, leading to loose connections or even complete failure of the bulb.

Furthermore, heat can negatively impact the electronic components of modern bulbs, such as LED bulbs. High temperatures increase the risk of electronic components overheating, which can cause them to malfunction or fail altogether.

Therefore, it is crucial to ensure that bulbs are not exposed to excessive heat to prolong their lifespan and maintain their functionality.
