What Are LED Lights and How They Should Ones First Choice of Lighting?

What are the LED lights?

There are several types of lights in the market like incandescent, fluorescent, etc. But out of them, the LED lights are one of the most recent yet most highly preferred lighting options among people. LED or Light Emitting Diode is a kind of lighting fixture, in which the light source is illuminated by the electricity that passes through a microchip. Also, to make it more efficient the heat produced is collected back into a heat sink. This makes sure that the bulb does not get overheated and that it does not get burnt out. This kind of heat management makes it one of the most used lighting fixture with an Energy Star. They are almost 90% more efficient than other kind of lights. They also have a longer life than incandescent and CFL's.

How it is different from other light sources?

The main things that make LEDs more preferred than the other forms is that they are more versatile in use, more efficient and have a longer life period.

The direction of light:

LED lights are unidirectional; means they will source their light is a specific direction only which is perfect for various applications like traffic lights etc. This also means that it will be using the energy efficiently. CFL and incandescent, on the other hand, throw light in every direction, increasing the power consumption and heat production.

Producing white light:

LED light in the original state is of red, blue, green and amber, but a layer of the phosphor is used to turn it into the white light. Whereas in CFL the light is produced by UV light and heat which, when strikes phosphor gets converted to white light and in incandescent, the white light is produced when the metal filament glows till it gets white hot. In both the CFLs and incandescent the heat production is too high as compared to LED.

What are the benefits of using LED lights?

There are various advantages of using LED light fixtures for one's home and offices. Some of them are:

Save energy: they use less electricity and thus will reduce one's electricity costs and consumption substantially. These are great for room and spaces where one would need lights all throughout the day.

Longer life: LEDs do not fail or get burned out like others and also can have a life of approximately 50,000 hours. This means one will not have to buy them again and again and can also save the cost of changing lights, especially in a commercial space.

Durability: they do not break easily and are also resistant to any other kind of environmental conditions. They are also not affected by constant on and offs as their performance do not get degraded after numerous cycles.

Cold resistant: LEDs work more efficiently in colder temperatures, unlike other lightings. This is the reason why they are highly used in freezers, cold storages, parking lots and boundary lightings.

No harmful emissions: unlike incandescents which has a production of UV and IR, however in LEDs, there is almost no UV or IR emissions thus preventing any kind of burn and heating hazards.

Why Is an Engineering Diploma a Wise Decision for You?

What if we told you that a number of academic programmes can be completed in a significantly lesser time? Would you still prefer that four-year degree? Ofcourse, it's definitely the first thing you may have envisioned for yourself when you were trying to decide your career path. But, in many cases, a diploma might be the best answer.

Should You Use Two-Factor Authentication

What exactly is two-factor authentication and what started it? Two-Factor Authentication happens when you are required to use two types of identification to log into a web site or open your email. It was started because people were using weak passwords or no passwords at all.

Normally the first factor is a password. As a reminder, your passwords should use numbers, capital and small letters and symbols. They should not be any sort of dictionary word and be at least 12 characters long, the longer the better. You should never reuse a password. If used correctly, you will need a password manager to remember them all. Getting one it is well worth it.

The second factor can vary widely from fingerprint or facial recognition to the web site sending you a numeric code via text or email that you must enter into their web site as part of the log in process. Google, Microsoft and others are working on other methods of authentication that will be secure and make it easier for the end user.

The best type of security is the one that people will use. Two-Factor Authentication takes a little longer to log into a web site, it will add 15-30 seconds. That time would be time well spent to protect your security. Web sites; especially banks, financial and health care sites, want to be sure that when a user logs in it is in fact the correct person. This is very difficult to do with just a password. Think about all the passwords stolen last year due to hackers.

This is where your phone is used to confirm your identity. Say you log into your bank's web site. If you use your phone for that login, your fingerprint or facial recognition can be used to ID you. If you use a desktop computer, they will usually send a numeric code to your phone that you use during the login process. In either case you gave the bank your mobile phone number, so they have at least some assurance that it is you. You also enter your password that matches what the bank has on file. This is how Two-Factor Authentication works, two types of identification.

As I stated earlier, web sites and companies are working to make this login process easier and more secure. This is a hard job as easier and more secure don't always work together.

4 Features to Look for When Buying a 3D Printer

If you are looking for a good 3D printer, make sure you consider the most important features first regardless of your purpose. 3D printers are used for various purposes, such as model making, research, prototyping, medical, manufacturing and so on. Although there are many features to take into account when buying, we are going to discuss the most important ones in this article, such as cost, speed and resolution. Let's delve into detail.

Resolution

As far as the resolution is concerned, make sure you consider the type of objects that you want to print with the machine. For instance, if you want to print models that have a lot of detail, excellent surface finish and extreme precision, make sure you opt for the right type of machine.

For higher level of details, you may want to opt for a DLP one. They are the most recommended choices. Other types, such as SLA and FDM won't allow you to get fine details. Although large-scale items don't require fine detail. Therefore, the use of an HD printer in order to create this type of parts is just the waste of resources and time.

Speed

As far as the printing performance is concerned, the speed of the machine is of paramount importance. Time is money. Today is the age of speed. If you are slow, you won't be able to beat the fierce competition in the market. Therefore, it's a good idea to opt for a machine that offers fast speeds.

Whether you want to print a figurine, ring or a functional part, make sure you choose something that offers a reasonably high speed. Although it's important to get accurate results, speed is a factor that can't be underestimated. Doing things quickly is really important in the here and now.

Cost

Although buying a 3D printer that features high speed and resolution is important, cost is another factor that should not be ignored at any cost. Some suppliers will suggest that you should opt for a service plan, expensive materials, and maintenance costs while you already have paid for the machine.

To save a great deal of money, we suggest that you choose a machine that uses affordable raw material and accessories in order to serve multiple purposes.

Size

As far as buying 3D printers is concerned, size is one of the most important factors to consider. Based on the size of the object you want to print, this factor should be considered carefully.

Apart from this, the print bed size may also offer better resolution since multiple objects can be easily printed. When looking for this feature, don't forget to consider the technical specifications as far as build volume and size is concerned. While buying a big machine will cost more, making a compromise on the cost is not a good idea. Instead, you should buy something high quality even if you have to spend a bit more.

In short, these are some important factors that play a great role when you are buying a 3D printer. Don't just buy a product just because it looks pleasing to your eyes. Make your decision based on the factors given above.
