LED STRIP LIGHT SMD VS COB TYPE

The dots of LED Strip Light is no more a headache, LED lighting has come a long way since its introduction, becoming more compact and cost-effective with each new technological advance. When choosing the right lighting for your application, it always important to understand the evolution of LED chip styles and the differences between them.

We all need lights that can guide us through the darkness and show us the right direction. That is why choosing a suitable LED light is so important. However, various models of LED lights are highly popular than the traditional incandescent lights because LED lights can last 25 times longer with less energy consumption.

So, you may have heard about COB LED and SMD LED. We will in detail about both

What exactly is COB LED and what is SMD LED and of course which one is right for you. Each model has its benefits, and now I will walk you through why a person would choose one versus the other for their particular application.

And here our comparison about top 2 LED Strip Light types  for you;

1. COB - CHIP ON BOARD LED STRIP LIGHT
2. SMD - SURFACE MOUNT DIODE LED STRIP LIGHT

1. COB - CHIP ON BOARD LED STRIP LIGHT

One of the latest developments in LED industry is COB or “Chip on Board” technology which is a step forward for more efficient energy use. Similar to SMD, COB chips too have multiple diodes on the same surface. But the difference among LED light COB and SMD is that COB LEDs have more diodes.

Chip on board, or 5050: 3 chips, a COB LED light source can have multiple chips (dozens or even hundreds) on the same Printed Circuit Board (PCB).

The COB has a printed circuit board on its substrate; diode chips are arranged in parallel or/and in series, based on the circuit of the PCB. The substrate can be either in aluminum or ceramic. The ceramic type has an improved thermal conductive performance which can guarantee a lower LED working temperature. Although the COB LED integrates various chips into one substrate, it only has two metal joining points: the anode and the cathode.

As the COB mounts the chips directly to the substrate, which has a large cooling area, the COB has superior thermal conductivity compared to the SMD. As a result, when we design a circuit on the substrate, we may consider shortening the chips distance to get the COB size as tiny as possible.

2. SMD - SURFACE MOUNT DIODE LED STRIP LIGHT

SMD refers to the term “Surface Mounted Device” LED Strip Lights, which are the utmost shared LEDs in the market. The LED chip is eternally fused to a printed circuit board (PCB), and it is especially popular because of its versatility. The PCB is built on a rectangular-shaped, flat object, which is what we usually see as SMD. If you look into SMD LED closely, you can see a small black point right in the center of the SMD; that is the LED chip. You can find it in light bulbs and filament lights and even in the notification light on your mobile phone.

There are multiple sizes of SMD LED chips: 2835, 3030, 3014, 5050, 5630; they are termed according to their dimensions: length and width. For instance, the size of the 2835 is 2.8 x 3.5mm, 3030 is 3.0 x 3.0mm, 3014 is 3.5 x 2.8mm, 5050 is 5.0 x 5.0mm, and 5630 is 5.6 x 3.0mm. The SMD chips are small and close to the design of the flat, square computer chip.

CONCLUSION

Due to the development of SMD LED technology, the high powered SMD, like the 3030 SMD, which has 0.9w rated power, is available to the market now. Hence, to make a high-powered floodlight with SMD, such as 100w integrated solar street lights or 70w high mast lights, became possible.

To conclude, I would like to say that both the SMD and the COB have wide applications, but the SMD is relatively customized to meet various fixtures. Though, you can choose between SMD or COB types depending on your needs for energy efficiency and versatility.
