LED Strips have long been a popular DIY lighting solution for a wide range of applications. That is why we are so excited about COB LED strips, the most recent LED Strip technology. Continue reading if you’re already familiar with strip lighting and want to learn more about how COB strips improve the world of LED lighting!

What Is A COB LED?

In the LED industry, COB light strip stands for Chip on Board, and it simply means that the LED die is packed directly on the circuit board (PCB). The ‘Chip on Board’ LED on flexible strip lights is also known as a flip-chip.

The COB LED strip generates higher light levels with a more uniform look than its predecessors. COB technology enhances light dispersion, removing the dark and brilliant spots generated by narrow beam fittings. Furthermore, COB LEDs are more dependable and last longer than SMD LEDs.

How is COB LED Strip Made?

Elstar, a maker of LED strip lights, makes LED Strip lights using the same high-quality PCB as their other LED Flex Strip lights. The flip-chip LEDs are then arranged side by side down the centre of the strip light, such that each metre of strip light has 512 LEDs! The strips are finished when a phosphor coating is put to the LEDs. This regulates the colour temperature while also protecting the small flip-chip LEDs beneath.

Some of the advantages of adopting COB LED light strips are as follows

No LED Hotspots, even in close spaces

One of the most prevalent concerns is about hotspots that span the length of a normal LED strip. A hotspot is a term used to describe the brighter areas of a fixture or strip where the source of the light can be clearly observed. It is significantly more pleasant and enticing when light seems to be a smooth source of light rather than a splotchy mishmash.

The bigger diodes in 5050 SMD Flex Strips are packed close together so that the light is spread out and constant on the surface being lighted from a distance, but if the lights are too near to the surface of the strips, the hotspots are an eyesore that the human eye cannot ignore.

With 512 LEDs/M, it would be impossible to locate any hotspots on the COB light design. The strip emits a smooth, continuous light from start to finish. The homogeneous light has no dark regions and is far more pleasant to the human eye, providing consistent light even in small places. Indeed, the only way to see hotspots is to look at the back of the strip, where the individually positioned flip-chip LEDs are more visible.

Only after dimming the strips to around 5% light output will you be able to see the individual LEDs. COB Flex Strips are so ideal for applications such as:

  1. It is impossible to hide the strip itself
  2. The strip light is within 2 feet of the surface that is being lighted
  3. Granite and glass both reflective surfaces are around
  4. Those applications where a cool neon effect is desired

Brightest COB LED

COB LED technology generates a much brighter light than previously! At 1400 Lumens/meter, these are even brighter than the high-density strips. Because flip-chip LEDs are not contained in a plastic holder like SMD LEDs, they generate dazzling, consistent light from a wider angle. This allows them to create light from the sides of the strip, which extends over 180 degrees. A broader light angle provides more light for you, which is critical for long-term brightness.

Highly Flexible

These bespoke LED lights are far more flexible than traditional flexible strips due to the smaller diode size and even weight distribution. Because the diodes are so tiny and tightly spaced, every spot on the strip is the same.

Because of the uniformity, installing strips is straightforward, since there is no need to account for a 5050 SMD LED projecting where it isn’t needed. Because of their greater flexibility, they will be simpler to fit into narrow areas and navigate around corners in your application.

Highly Efficient, Less Heat

When so many LEDs are squeezed into such a small space, efficiency is called into question. In terms of efficiency and heat transmission, flip chip LEDs beat conventional LEDs. They consume the same 14 Watts per M as our high-density strip lights, but they generate 100 Lumens per Watt as opposed to 75 Lumens per Watt for the high-density strip.

Because the brightest COB LED is attached directly to the flexible PCB board, it is also much better at dissipating heat. This enables them to transmit heat from the light source to the PCB rather of retaining it entirely within the light source. Because of the decreased thermal resistance in the high-density circuit, the LEDs’ lifespan is significantly extended.

High Color Rendering Index

COB strips can increase colour reproduction, make an object look more vivid, and highlight details.

If you have higher color reduction requirements and want the light to better restore the color of the object itself, making it look more realistic and eye-catching, use Elstar’s high CRI COB LED strips, which have a color rendering index of over 90 when compared to SMD LED strips, which have a color rendering index of around 80.

Electrical Properties of COB LED Strips

If you’ve been paying attention, the advantages of COB LED Strips should be evident, so let’s go into some specifics about this strip. Much of this may look familiar if you’ve worked with LED strips previously, but there are a few differences with this strip, so read the guidelines below before dealing with COB Strip Lights.

COB LED Strip with 24V Power

The COB strips are powered by a 24VDC power supply. Our other flex strips are powered by 12VDC, thus this is a variation from the norm. Extra voltage is necessary since there are so many diodes squeezed into the circuit. Please bear in mind that these strips demand constant 24V power. Fortunately, we have a wide range of 24V power supplies in a number of styles:

  • Dimmable
  • Hardwired
  • Plugin
  • Open Frame

Long Run Lengths

Aside from the higher input voltage, there is another benefit. Longer runs are available with the COB Flex Strips. End to end, they may be joined for as long as two complete reels (32.8 ft.)! This makes it easier to develop applications that demand long straight lines. If you require more than 32.8ft of LED Strip, remember to connect them in parallel to minimise voltage loss.

Easy Cut and Connect Installation

COB LED strips are available in typical white outputs such as Cool White, Warm White, and Neutral White. In the COB light design, RGBW COB light alternatives are also available.

Electrical Properties of COB LED Strips

The quality of light produced by COB LED lights and SMD LED lights would be noticeably different. This is partly because they each employ a different number of diodes, which affects the brightness and range of light.

When it comes to SMD, the resultant light is glaring and should be used as a spot light. This is due to the light created as a result of many light sources being connected.

COB, on the other hand, will produce consistent, glare-free light. It generates a light beam that is uniform and easy to manipulate. This is mostly because to its wide-angle beam, which makes it a more effective light source.

Conclusion

The COB LED Strip is the most latest technology to enter the market, and it removes the problem of visible LED dots. Consider COB LED Flex Strips if normal LED strips aren’t cutting it for your project. These LED strips are new to the market, but they will quickly become commonplace in the world of LED Strips.
