Nowadays, perhaps LED lights are so popular that everyone knows about them. But did you know that LED lighting was originally just an experiment a century ago and was only developed in the 60s and 70s. LED lights at that time still had many weaknesses, and most people still relied on incandescent and fluorescent lights.
However, starting from the 90s, LED lights are gradually taking over the lighting industry almost completely. So why has it grown so strongly? Let's join NLT Group to find out the advantages/disadvantages of LED lights in smart lighting before the wave of sustainable energy use!
Concept of LED lights
Simply put, a LED (Light Emitting Diode) is a type of electronic light source that uses LED technology to create light, operating by converting electric current through a semiconductor material, creating luminescence. from the principle of electronic self-illumination.
Nowadays, LED lights are not just a normal lighting device, but they are combined with many different technologies such as IoT, AI, etc. From there, creating a smart lighting system with many convenient features. useful and intelligent.
Typical examples include smart street lighting systems, which are automatically controlled to turn on and off lighting as well as lighting levels depending on different time frames and environmental conditions, thereby helping Save many different resources.

Advantages and disadvantages of LED lights in smart lighting systems
The advantage
Efficient energy consumption
LED lights are always known for their much better energy consumption efficiency than traditional lights such as fluorescent lights, incandescent lights... Specifically, it is estimated that LED lights have an energy efficiency of 80 - 90 % compared to traditional lamps. Energy efficiency in lighting solutions is measured by two types of statistics: useful lumens or luminous efficiency.
Next, LEDs convert almost 95% of the total energy into light and only 5% of the energy is converted into heat, in contrast to traditional incandescent bulbs with more than 90% of the energy converted into heat. This shows that the optimal energy consumption for lighting of LED lights is much more efficient than LED lights.
Using less energy also means saving a large part of your electricity costs, your monthly electricity bill will be significantly reduced. Considering the micro level, this indirectly helps reduce pressure and demand on the national power plant, contributing to reducing greenhouse gas emissions.
Environmentally friendly composition
For traditional solutions such as fluorescent lamps, incandescent lamps, mercury vapor lamps... they are often made up of mercury. Mercury has the ability to pollute the environment and is harmful to human health when exposed. By eliminating mercury from their composition, LED lights help reduce the risk of pollution and potential environmental and health risks.
Using LED lights will also significantly reduce some of your waste disposal costs through a registered waste disposal site.
Higher level of safety
A higher level of safety is one of the key advantages of LED lights over traditional lighting solutions. As mentioned above, most of the lighting energy of traditional lamps such as fluorescent bulbs and incandescent bulbs converts a significant amount of energy into heat. This not only wastes energy, but also easily causes danger with heat emission.
This is the first and main danger when we consider light bulbs. If you have ever accidentally touched traditional light bulbs, you probably know what they are like.
In addition, the fact that LED lights only use 5% of energy as heat, much lower than traditional types, also proves that LED lights can easily operate effectively in low voltage systems. Low voltage systems are always significantly safer when a fault occurs
High longevity and durability
When talking about LED lights, it is impossible not to mention its longevity and durability. This is the amount of time that the bulb will maintain good and effective operation. LED lights have an exceptionally long lifespan compared to traditional lights. On average, the lifespan of an LED light can last up to 25,000 - 50,000 hours of operation. A significant number when traditional devices such as fluorescent lights are only capable of operating for an average of 20,000 hours.
In addition, when it reaches its maximum lifespan, LED lights will not burn out or short out like other types of lights, but will only gradually lose their brightness. A typical example of the longevity of LED lights can be the smart LED lighting system of NLT Group. With a lifespan of up to 60,000 hours, an amazing number when compared to today's lamps.
Easily integrates with smart systems
In the process of urbanization, applying smart solutions is always inevitable. And in the lighting system too, traditional lamps are difficult to integrate with smart solutions. Meanwhile, with LED lights, this is extremely easy thanks to its flexibility.
LED lights can be easily compatible with smart lighting systems with many features such as automatically turning on and off, adjusting brightness, remote control through applications... Meet the needs of using such devices. today's high-tech equipment.
To make it easier to imagine, we can mention NLT Group's smart lighting solutions, including different solutions for lighting factories, streets, advertising banners, stadiums, etc. The application of the system Smart lighting system with LED lights helps managers easily control lighting devices via Website or Mobile App, easily detect and maintain devices, save energy and is extremely easy to use. and convenience.
Defect
Initial price
Although the benefits that LED lights bring are many, some people are still hesitant to buy LED lights for lighting, especially investing in large quantities because the initial cost is often quite high. If you only use it for a short period of time, the cost of LED lights may be higher, but if you use them for a long time or for large purposes, then surely LED lights will help you not only optimize lighting but also also saves a lot of costs.
Compatible with technology
To take full advantage of the smart features of LED lights, users need to use smart devices such as mobile phones or computers. This can create a barrier for those unfamiliar with the technology
Environment temperature
LED lighting is often sensitive to the temperature of the surrounding environment. Therefore, their effectiveness will also depend directly on the environmental temperature level. If continuously exposed to too high temperatures, they may break down sooner than expected.
Summary
So it can be seen that although there are some limitations, the advantages of LED lights are the most significant. Furthermore, with the development of current technology, those disadvantages have gradually improved and are no longer a big problem for users. Hopefully through the article, NLT Group has helped you gain a deeper insight into the advantages and disadvantages of LED lights. Please follow us and look forward to upcoming interesting articles!
