Are you still using incandescent bulbs for lighting up your home? If yes, then you are missing out on many advantages that LED bulbs can offer you over the incandescent ones. From saving your energy to lasting longer than usual, LEDs can make a huge difference in your lives. The prevention of an increase in electricity bills is one of the most obvious reasons why many people tend to prefer LEDs.
Sticking to the old incandescent bulbs won’t remain as a choice as some of them are being terminated. Hence, opting for LEDs will become a must for you. However, before setting off to purchase, there are many informative factors that require your concern and attention. Take a ride with us while we go through every detail that you need to know about LED bulbs.
Do LED Bulbs Heat Up?
When it comes to tungsten filament bulbs, having bulbs of 100 watts means that it can only generate 10 watts of light. And the rest of the 90 watts will just be heat. However, when it comes to LED bulbs, you will often come across the popular fact about them that they do not heat up. So, is it absolutely true?
Well, we can say that it is correct to some extent. You will be able to touch LED bulbs easily as they do not generate IR radiations that can turn them hot to touch, unlike incandescent bulbs. Due to the production of IR radiations, other bulbs heat up significantly. Hence, it becomes impossible to touch them without waiting for them to cool down.
No doubt that LEDs are far more efficient as compared to the tungsten bulbs, but they do produce some heat as well. If you choose to buy a 100 watts LED bulb, the output of light that you will is up to 70 watts. While the rest of the 30 watts will be heat energy. The following comparison will let it be easier for you to understand the difference:
- With 100 watts of input, the LED bulb can give an output of 70 watts and generate 30 watts of heat.
- With 15 watts of input, the LED bulb can give an output of 10 watts and generate 5 watts of heat.
- With 100 watts of input, the tungsten filament bulb can give an output of only 10 watts and generate 90 watts of heat.
Does Heat Affect The Lifespan of LED Bulbs?
Are you concerned about the lifetime of your LED bulbs? It is undeniable that LED bulbs are relatively efficient. However, the generation of heat can change this fact for you. Due to the heat that these bulbs produce, the efficiency can get immensely compromised.
The temperature of the surroundings and parts of the bulb, like the lens and drive, are responsible for affecting the temperature at the junction of the LED. LED lights possess a lot of parts inside them to change the electricity from your home’s outlet to the lower voltage that is responsible for running the LED chips. This factor makes the LED bulbs far more heat-sensitive than other lights such as incandescent bulbs.
If you have bought relatively inexpensive LED bulbs, there is a high chance of them coming with a caution regarding the use. The warning forbids you to place these bulbs in entirely closed fixtures. You have to avoid using such fixtures as they can decrease the lifespan of your lights due to the enclosed heat.
Using enclosed fixtures is only favorable when you have bought a high-quality bulb that comes with a warranty tag. Usually, the LEDs are not prone to get burnt out. However, heat can lessen the quality of light they produce. The dullness that takes place throughout the time span is known as light depreciation.
How To Prevent Light Depreciation In LED Bulbs?
For the prevention of light depreciation, LED bulbs come with integrated heat sinks in them. This component is responsible for absorbing the generated heat so that it does not have adverse effects on the efficiency of the bulb. The placement of heat sinks makes these lights last longer than incandescent bulbs.
What Are LED Bulbs?
LED is basically a short form having initials only. The full form for LED is ‘Light Emitting Diode.’ These devices are semi-conductor in nature, work by giving out visible light whenever electric currents get passed through them. LED bulbs are capable of showing far more efficient working than incandescent bulbs. Relatively they have the potential to show more than ninety percent of efficiency in their functioning.
How Do LED Bulbs Work?
Do you know why the invention of LEDs initiated innovation and advancement in this world? Well, it is due to the inexpensive production of light that you will be able to get through them. LEDs have successfully modified the whole industry for the better, and this technology’s possible uses are unlimited.
The working of these bulbs is quite simple as well. In simple words, the small LEDs fitted in these bulbs lighten up whenever the microchip of these lights senses the passing current. LEDs produce light premised on the diode’s P-N junction.
It won’t be entirely true if we say that the LED bulbs do not get heated up. Just as all electrically-powered devices, these bulbs also generate heat. However, the difference is that the generated heat is too low that they do not even become hot to touch.
Still, the efficiency of LED lights can get compromised due to the heated junction. For this reason, placing these lights in fully enclosed fixtures won’t be favorable for you. Hence, being wise in selecting the right fixtures for your LED bulbs is extremely important.
Although LED bulbs will not burn or get failed, still, the light that they produce can become dull over time. The light depreciation of these bulbs is due to the heat that they generate. Hence, the effect of this factor will impact the whole durability of your bulb.
For ensuring a longer lifespan and prevention of lumen depreciation, the LED bulbs come with heat sinks installed in them. These sinks will absorb the additional heat to make sure that the performance of the device does not get disturbed.
