From smart bulbs you can control with your phone to advancements in light quality and spectrum, there’s always something new just around the corner.
The Science Behind Light Bulbs
Light bulbs may seem simple at a glance – flick a switch, and your room is bathed in light. But have you ever paused to ponder what really happens when that bulb illuminates? The science is quite fascinating.
At its core, a light bulb is an electrical device that produces light from electricity. The three main components of a traditional bulb are the filament, the glass enclosure, and the inert gas inside the enclosure. When you switch on a light, electricity flows into the filament, heating it up until it glows – a process known as incandescence.
This process is not 100% efficient. In fact, most of the energy from an incandescent bulb is lost as heat. That’s why the shift to more advanced light bulbs like LEDs is crucial. LED technology relies on semiconductors to convert electricity directly into light through a process called electroluminescence. This is a fancy term for what happens when electrons pass through a material and release energy as photons – those are the light particles. With LEDs, more electricity is converted into visible light, meaning less waste and a brighter beam per watt.
Let’s take a look at the efficiency comparison in lumens per watt (lm/W), the measure of a bulb’s brightness output divided by the power it consumes:
| Bulb Type | Efficiency (lm/W) |
|---|---|
| Incandescent | 10-17 |
| Halogen | 16-22 |
| CFL | 35-60 |
| LED | 80-100 |
What this means for you is that when you’re completing your home DIY projects or lighting up your workspace, choosing an LED bulb can offer you the most light while consuming the least amount of power. Plus, it’s easier on your wallet in the long run.
