Understanding Why LED Bulbs are Regarded as Being More Efficient Than incandescent Bulbs

People who sell LED bulbs tend to keep on asserting that the said bulbs are more efficient than incandescent bulbs. And for the most part, people who have actually gotten to use the LED-based bulbs tend to agree that these bulbs are much more efficient than the incandescent bulbs. That is the case even for the more sophisticated forms of LED-based bulbs, including the so-called LED MR16 Bulbs. Indeed, it would seem that it is through the more sophisticated types of LED-based bulbs, like the LED MR16 bulbs alluded to, that the efficiency of the LED-based bulbs tends to be more clearly manifested. Most people tend to be satisfied with the plain explanation that LED-based bulbs are more efficient than incandescent bulbs, without pressing the matter further. But the critical thinkers tend to press on: to understand exactly why (as in, through what mechanism) the LED-based bulbs -- including the LED MR16 bulbs we have alluded to – are more efficient than incandescent bulbs. That is the question we will attempt to answer.

Now the first step in answering the question as to why LED bulbs are regarded as being more efficient than incandescent bulbs is the one where we seek to know how the efficiency is measured, in the first place. And this is where we come to learn that efficiency, in this particular context (as in many other contexts) is measured when output is viewed against input. Under that scheme, the LED-based bulbs (including and especially the more sophisticated ones like the LED MR16 bulbs we mentioned earlier) are regarded as being efficient for one reason. The reason is that their output, in terms of the light energy they produce, is high -- compared to their input (in terms of the electricity they consume). So that is why they are regarded as being more efficient.

The second step in answering the question as to why LED bulbs are regarded as being more efficient than incandescent bulbs is to dig deeper, and understand why the output to input ratio of the LED bulbs is higher than the output to input ratio for incandescent bulbs. To answer this question, we need to understand how inefficiency is introducing into this paradigm. That is where we come to learn that inefficiency normally comes in when some of the electrical energy that was supposed to be converted into light energy is instead converted to (and hence wasted as) heat energy. Now that effect, where energy is wasted as heat, is more pronounced in the incandescent bulbs, than in the LED-based bulbs.

The third step in answering the question as to why LED bulbs are regarded as being more efficient than incandescent bulbs lies in understanding why more energy is wasted (in the form of heat) in the incandescent bulbs. To understand this, you have to appreciate that incandescent bulbs only get to produce light energy when their filaments are heated (using the inputted electrical energy) to such an extreme degree that they become ‘white hot,’ thus producing what is perceived as light. So a lot of energy is wasted as heat under this scheme. The working of LED-based bulbs, on the other hand, doesn’t involve the heating of filaments, but rather, the passage of electrons through diodes (the light emitting diodes) to produce light. In the latter case, there is less wastage of electrical energy: hence the greater efficiency of LED bulbs.
