What is the Difference between SMD and COB LED Lighting?

SMD means Surface Mounted Device and COB stands for Chip On Board. Light emitting diode or LED for short has become highly popular. The Surface Mounted Device (SMD) was initial presented in 2008. Whereas, the COB LED technology has been available since 2010 in Guangzhou at the Canton Fair.

These SMD chips are of various colors such as Blue, Green and Red which helps produce tinted lights. The COB LED lights are either ceramic or light weight aluminum.

What is an SMD LED Light?
SMD lights use SMT technology which places the LED chip onto a PCB. The PCB board is constructed in a flat item, rectangular-shaped, and is what one said as an SMD. One can see a tiny black point at the center of the SMD if you look carefully in an SMD LED, it is the LED chip. The rear side of it has two steel points (cathode as well as anode) which are made use of for soldering with the circuit for the light.

The 5050 SMD has three steel points as there are three chips inside. The SMD Led has different types, such as 5730, 5630, 5050, 3030, 3014 and also 2835. Each of these is called according to the measurements of the LED meaning it is based on the width and length. Prior to the COB was created, the SMD 5050 as well as 3528 was made use of.

What is a COB LED?
The COB LED uses the brand-new encapsulation innovation. As compared to the SMD 5050: 3 chips or the 3528: 1 chip, the COB LED has numerous chips on the same printing circuit board (PCB). The PCB gets on the substrate of the COB. The diode chips of the COB are ranged in series/ or parallel which depends upon the circuit. This substratum can either be ceramic or light weight aluminum. If you are searching for a much better thermal conductive efficiency, then the ceramic type is what you need as it will guarantee a much lower LED running temperature.

The COB LED has 2 metal link points, the cathode and anode. The COB has a better thermal conductivity as compared to the SMD, due to the fact that it mounts chips straight to the substrate that has a substantial cooling space. In order to have the COB dimension to be as little as possible, the circuit needs to be made to reduce the chip’s distance.

Verdict
COB LEDs are available in different forms which make it easier for them to be utilized for different fittings. Whereas, SMD lights can just be made use of for restricted fittings, there are lots of advantages of using COB LED lights such as far better thermal conductivity as well as lower manufacturing failing rates as a result of the patent layout.

Choosing between SMD and COB LED lamps relies on your requirements. Both of the lights are being utilized for various applications. When choosing in between the two lights, first know about which fixture is being used for. LED lights have changed the entire lights market.

How to choose the right beam angle for LED lights

The right beam angle of the LED lights plays a huge role which is why it is important to choose the right one. Nobody likes walking into a dimly lit space. One of the reasons behind it is the wrong beam angle of the lights. In this post, you will learn how to choose the right beam angle for LED lights.

What’s a beam angle for LED lights?

It is the angle for the LED light which spreads across the area when the LED light gets switched on. Beam spread is another name which is used to describe it. Choosing the right beam angle allows the building to have the type of visibility and ambience that you want. The main consideration of the beam angle for LED lights is the space that should be lit. There are certain considerations which need to be taken into account.

  1. Building Type

The first thing which needs to be considered is the building type. You have to consider how many lighting fixtures would be needed for the building. It is only then that you would be able to choose the right beam angle. The beam angle depends on the height of the ceiling as it impacts the visibility and illumination. An example would be a warehouse that has high ceilings that would require an LED high bay light that has a different beam angle as compared to a retail outlet.

  1. Number of LED Lights

The number of lumens required for a space needs to be determined and in order to do the number of LED lights needs to be considered. For a commercial space, 70 lumens would be needed per square foot. A lighting layout design plan is a great way to figure out the beam angle for LED lights. To get a number in total lumens, the industry standard would be multiplied by the area of the building.

  1. Height of Light Fixtures and Ceilings

The height of the ceilings needs to be checked to ensure that the beam angles overlap. Overlapped beam angles ensure that the entire space has been covered by light which helps prevent any injury. Normally, the height of a ceiling is anywhere around 7.9 and 8.9 ft. Therefore, a wider beam angle of 60 or more degrees would be sufficient. However, if the ceiling height is over 8.9 ft then a narrow beam angle that is below 45 degrees would need to be considered.

  1. LED Light Bulb Type

Now, it is important to consider the LED light bulb type as it influences the amount of light that is given to a space. There are different types of LED bulbs out there. For example, in industrial spaces that have high ceilings, the higher the lighting fixtures, the narrower the beam angle would need to be. As for a lower ceiling, the beam angle needs to be wider. A reflector which be needed if you are using high bay lights.

How to choose the right IP rating for interior and exterior LED lights

There are different types of LED lights that have the IP rating which you might have come across. Did you know what an IP rating is? In this post, you will gain some tips about the IP rating for interior and exterior LED lights which will help you choose the right one.
1. Types of Different LED Lights That Are Waterproof
Everyone knows that when water and electricity meet, something is bound to happen. It can lead to a deadly shock which could even be life-threatening at times. Water can ruin the LED lights quickly or over time and that is why waterproof LED lighting is the way to go. It will also help extend the lighting fixtures life. IP rating IP65 is mostly used for waterproof LED like the LED street light or LED flood light. The waterproof levels vary significantly due to different IP ratings.
The complete waterproof LED lights are different from the water resistant lights. The difference between the two is that waterproof lights are designed to sustain any amount of water, while the water resistant lights can only work for a certain amount of time as exposure to water affects them. There are various advantages to LED lights such as energy saving.
2. IP Ratings for LED Lights
There are different Ingress Protection ratings for outdoor and indoor lights. The rating is used for the measurement of protection that the LED light would have against solid and water. Two numbers are used in the IP rating. The first is from 0 to 6 which is a solid IP rating and shows the resistance against solid. While the second is 0 to 8, this shows the protection against water.
IP67 Rating
LED lights that have an IP67 rating provide complete protection against water and solid. They are quite similar to IP64 and IP65. Even if the LED light is immersed in water depth of 1m there would be no effect. IP65 LED lights are the most common waterproof LED lights. Maximum protection against solid and liquids is provided. They can be used for both commercial and domestic purposes. However, if the lights are to be used in place where there is a risk of water, then LED waterproof lights would be needed.
IP65 Rating
They are great for protection against water jets and foreign bodies. If water is disposed by a nozzle of just 6.3mm, it would cause no damage. It is perfect for outdoor lighting fixtures.
IP64 Rating
This is the highest rating for the most LED corn light bulb. It provides good protection against solid and liquid.
IP54 Rating
They have complete dust protection. But for liquids, they only provide protection against splashing water which is why they are common among indoor fixtures.
IP40 Rating
They are used in an indoor or enclosed fixture. It should not be used in the outdoor and only for the indoors unless there is a lot of humidity.
