Basic Knowledge

You might have heard that LED lights are much cooler than other types of lights. Is that true? Let’s find out everything you need to know about LEDs and heat!

First of all, you should know that LED lights do produce some heat. That’s normal for any electrical device that uses power. You know how plug sockets get warm, right?

But don’t worry, LED lights are still much better than older lights. For example, incandescent bulbs waste a lot of energy on heat. They only turn 5% of the energy they use into light, and the rest is heat! That’s why they can burn your fingers if you touch them.

LED lights are much more efficient. They use about 90% of the energy they use to make light, and only 10% is heat. That means they save you money on your electricity bills and help the environment.

How hot an LED light gets depends on the quality of the light and how well it is designed. A good LED light has a heat sink that absorbs the heat from the LED and transfers it to the air. This keeps the LED from overheating and losing brightness.

A simple way to compare LED lights with other lights is to look at the surface temperature. The surface of an LED light is usually half as hot as a halogen or incandescent light of the same brightness. It is also about 20% cooler than a CFL light.

How Do LEDs Stay Cool?

You might have noticed that LEDs can get quite warm when they are on for a long time. This is because they are electronic devices that use electricity to produce light, and some of that electricity is wasted as heat. Unlike other types of lights, such as incandescent or halogen, LEDs do not release much of their heat into the air. Instead, they keep most of it inside their tiny chips, which can damage them if they get too hot.

That’s why good quality LEDs have clever ways of cooling themselves down, such as using heat sinks. A heat sink is a metal part that attaches to the LED and helps to transfer the heat away from the chip to a cooler place. This way, the LED can work more efficiently and last longer.

In the past, LEDs had their heat sinks on the outside, which made them look bulky and unattractive. But nowadays, many LEDs have their heat sinks hidden inside, which makes them look sleek and elegant.

If you want to learn more about how LEDs cool themselves, you can watch some interesting videos on YouTube, such as this one that shows how to cool a super bright 100W LED module, or this one that explains the basics of LED light building and cooling. You can also read some articles on the web, such as this one that gives an overview of thermal management of high-power LEDs, or this one that discusses lumen maintenance and reliability of LEDs.

Can I Touch An LED Bulb?

ED bulbs are a type of light source that use light-emitting diodes (LEDs) to produce light. LEDs are semiconductor devices that emit light when an electric current passes through them. LEDs have many advantages over other types of bulbs, such as incandescent, halogen, or fluorescent. Some of these advantages are:

  • LED bulbs are more energy-efficient than other bulbs, meaning they use less electricity to produce the same amount of light. This can save you money on your energy bills and reduce your carbon footprint.
  • LED bulbs last longer than other bulbs, meaning they need to be replaced less often. The average lifespan of an LED bulb is about 15,000 to 50,000 hours, depending on the quality and usage of the bulb. That’s equivalent to about 14 to 45 years of continuous use!
  • LED bulbs are more environmentally friendly than other bulbs, meaning they produce less heat and waste when they burn out. Heat is a major source of greenhouse gas emissions and can contribute to global warming and climate change. Waste is also a problem when old bulbs end up in landfills or oceans, where they can harm wildlife and ecosystems.
  • LED bulbs are more versatile than other bulbs, meaning they can be used in different types of fixtures and applications. They come in various shapes, sizes, colours, and brightness levels to suit your preferences and needs. They can also be dimmed or controlled by smart devices for more convenience and comfort.

However, LED bulbs also have some drawbacks that you should consider before buying them. Some of these drawbacks are:

  • LED bulbs are more expensive than other bulbs initially, meaning they may not fit your budget or offer the best value for money. The initial cost of an LED bulb depends on the brand, quality, size, and features of the bulb. However, this cost may be offset by the long-term savings on energy bills and maintenance costs.
  • LED bulbs may not be compatible with some existing fixtures or applications, meaning you may need to upgrade or replace them if you want to use them in your home or office. Some factors that affect compatibility include the shape and size of the socket or base of the bulb, the voltage and current ratings of the bulb, and the presence of dimmers or switches in the circuit.
  • LED bulbs may not be as bright as other bulbs initially, meaning they may not meet your expectations or standards for lighting quality. The brightness of a bulb is measured by lumens (lm), which indicate how much light it emits per unit area. The higher the lumens rating, the brighter the bulb. However, brightness is also affected by factors such as colour temperature (K), which indicates how warm or cool the light appears; colour rendering index (CRI), which indicates how accurately it reflects colours; and glare reduction (GR), which indicates how well it reduces reflections from shiny surfaces.

So which type of bulb should you choose: integrated or retrofit? The answer depends on your personal preferences, needs, budget, and existing situation.

Integrated LEDs are LEDs that are built into an existing fixture or application without requiring any modification or replacement. They offer convenience and simplicity as you don’t need to worry about finding a compatible socket or base for your bulb; installing a new circuit breaker; wiring a new switch; or changing an old fixture altogether.

Retrofit LEDs are LEDs that replace an existing fixture or application with a new one that has built-in LEDs. They offer flexibility and versatility as you can choose from different shapes, sizes, colours, and features for your new fixture; adjust its brightness, colour temperature, and colour rendering according to your mood or task; control it remotely with smart devices; or integrate it with other smart home systems.

Both types of LEDs have their pros and cons, so there is no definitive answer to which one is better. It depends on what you value more: convenience or flexibility; simplicity or versatility; cost or performance.

Looking After Your LED Bulbs

LED bulbs are a great choice for saving energy and money, but they also need some care to make sure they last long and perform well. Unlike traditional light bulbs, LEDs produce very little heat from the light they emit, but they still generate some heat from the electrical components inside them. This heat can affect the brightness and lifespan of the LED if it is not managed properly.

To keep your LED bulbs cool and happy, you need to choose the right ones for your fixtures and install them correctly. Some fixtures, such as downlights, are enclosed and have limited air circulation. This can trap the heat and damage the LED. That’s why you need to look for LED bulbs that are specially designed for enclosed fixtures. They have features like heat sinks or vents that help dissipate the heat.

You also need to make sure that the LED bulb fits well in the fixture and does not touch any other parts. If the bulb is too big or has the wrong shape, it can interfere with the airflow and cause overheating. The best way to avoid this is to measure the fixture and compare it with the dimensions of the LED bulb before buying. You can also check the label or the website of the manufacturer for compatibility information

By following these simple tips, you can enjoy the benefits of LED bulbs for a long time. LED bulbs can last up to 50,000 hours, which is 50 times longer than incandescent bulbs and 5 times longer than CFL bulbs. They also use up to 90% less energy than incandescent bulbs and 60% less than CFL bulbs5 This means you can save money on your electricity bills and reduce your carbon footprint.
