What is COB LED?
Before we define what is COB LED. Just know that’s a runaway success for companies that manufacture LEDs and circuit boards. The latter business models work in unison to bring their two biggest components together—in one piece. And there you have—a chip-on-board—COB LEDs. The latter is mass-produced in huge manufacturing units alongside integrated circuits and printed circuit boards.
But sometimes, the circuits and boards are outsourced from third parties as well. LED performs better than other lightning devices and technologies when put parallel —LED outsmarts them from a distance. The luminosity, efficiency, versatility, and compact nature of COB LED lightens our lives better.
1. Top Three Benefits from a Business POV
You may be thinking, how’s COB LED so convenient for the manufacturer, right? Well, three factors make these light-emitting diodes favorable. Firstly, manufacturing costs are lower compared to semiconductors. Secondly, they do not require excessive packages owing to their compact size. Third, they are lighter and compact and, thus, are easier to carry with minimum logistics outlay.
COB LED Definition: A Brief Breakdown
Although you have skimmed through the COB LEDs definition above—it’s only the top layer. To understand it better, you must view it as a construction of small parts. Speaking of which, it’s the miniature LEDs arranged in a tightly packed space. But the results are a dazzling bright light—with every unit of LED acting in concert. The impressive bright composition brings about the perfect illumination source ideal for theatres, moviemakers, photographers, events, sports, and more. In other words, COB LED use cases are countless; they cannot be expressed in words. Their overwhelming use in hospitals—in emergency rooms and ICU units has impacted our lives positively. Even flashlights and floodlights are indicative of the chip-on-board LEDs’ versatile nature.
COB LEDs’ Structural Overview
Chip-on-board LEDs feature multiple diodes—nine or less. However, there are only two point-of-contact units between the circuit and LEDs, regardless of diode numbers. You may see a panel-like structure of the COB LED because of the chip’s regular circuit design. The featured highlight is the multiple LED chips fixed and enclosed in a circuit board. This is the reason you see a compact, neat array of miniature diodes. This concentrated structure enables maximum light output—bringing in a balanced and bright illumination.
But do you know what makes the COB’s integrated LEDs even better—and more efficient? Well, thanks to its improved heat dissipation design. This is what keeps the lighting source even after prolonged use. The well-thought-out design nestling teensy LEDs provides enhanced and consistent light emission without causing unit burnout.
COB LEDs also come with an array of intricate components. These include an electrical power supply, a light-emitting chip referred to as a ‘die,’ and a phosphor coating. Giving the process in the pecking order: the miniature power supply drives energy to the LED; the light-emitting chip (blue light pump) emits blue photons when catalyzed; and the phosphor coating converts the blue illumination into white light.
Remember that the intensity of lighting depends upon the chip unit’s size. For example, sports ground flood lights may contain high-performance COB LED modules that can deliver up to 1,200 lumens of light (at 800mA approx..). Other major applications of these large-scale lighting units include industrial sectors, hospitals, airports, and more.
2. What makes COB LEDs Long-lasting?
Several factors determine COB LEDs’ longevity—and how long a single unit lasts. The four primary aspects of measuring LEDs are their type, size, intensity, and use cases. Skim through the following bullet points if you want to know more:
- Regulated and QC-passed COD LEDs are designed to withstand exposures to extreme heat. Thanks to their heat dissipation system—that combines a heat sink and thermal pads (with paste epoxy)—to overcome intense emission. Thus preventing overheating issues and reducing excessive strain on LED bulbs and chips.
- The well-thought-out, robust, integrated design of the COB LED is also a game-changer when it comes to longevity. Different segments and circuits, including diodes, are mounted directly on a single circuit board. Do you know why? Well, it’s because the form factor must correlate with LED lights’ total light emission (Luminous Flux).
- High-quality materials play a huge role in determining COB LED’s overall lifespan. The miniature circuit, semiconductor unit, enclosed wiring, and feeding of different components within the COB unit have a huge impact.
- Imagine a light source maintaining the color quality and light output unit. It seemed something virtually impossible to achieve—but only until traditional LEDs existed. COB LED is going strong for this exact reason. Thanks to its reduced light degradation system that controls overall lighting efficiency in due course. Thus, the lighting source powered with COB LEDs doesn’t wave or lapse even after extensive use.
- We recommend you look closer whenever you open a flashlight and inspect its components. You will be astonished to see a uniform assembly of components—sitting in perfect spots—for producing—the perfect white light. This, too, helps us evaluate the average lifespan of a COB LED source.

3. How do COB LEDs help Reduce Battery Consumption?
Who knew that the COB LED also has a breaking point when you have to choose between the lumen output (brightness) and runtime duration? It usually occurs when you buy or build a battery-powered lighting source. So, if you wish for a battery-backed source equal to the lumen outputs, things can get out of hand. You’ll run out of lighting power shortly—earlier than expected. So before you purchase a COB LED or make a DIY unit yourself, better that you consider the following factors:
Always buy QC-passed COB LEDs that guarantee higher efficiency while retaining battery power.
Purchase chip-on-board LEDs that are energy-efficient, i.e., require moderate electrical power (input) to produce prolonged lighting (output).
COB LED’s longevity means you don’t have to replace its components frequently. Thus, it helps you to converse battery, enjoy lighting for long hours, and do your work effortlessly.
COB LEDs come with advanced driver-sourcing circuits, dimming capabilities, and stabilization technologies to regulate high voltage. Thus allowing you to regulate control over light output without stressing the battery’s power.
COB LEDs generate less heat when compared to traditional incandescent light sources like house bulbs, lamps, and halogen bulbs.
COB LEDs vs. Normal LEDs: Key Differences
You must understand what surface-mounted devices (SMD) are and how they work. Surprisingly, it’s one of the most prevalent LED-based lighting systems available on the marketplace nowadays. The first thing you’ll notice about the SMD lighting systems is their mounted unit—where an LED chip fuses to a printed circuit board. But do you know what’s the most distinguishing feature? Well, it’s not the chip itself but the number of diodes therein.
COB LEDs vs. SMD LEDs: Key Differences
Since now we know that SMD LEDs are equally popular as COB LEDs, choosing between them can be challenging. But there’s no better way than to discern their differences, as it will help you pick one that fits your requirements.
Circuit Design:
COB LED has two contacts within one circuit, while SMD LED comprises 2, 4, and 6 connections.
Diodes per Chip:
COB typically has nine or more diodes on a single chip, whereas SMD can have up to three diodes per chip within each circuit board.
Appearance:
COB appears to have a panel-oriented design, while SMD LEDs look like a collection of miniature lights inculcated in the circuit design.
Lumens per Watt:
COB requires a minimum of 80 lumens per watt, while SMD generates 50 to 100 lumens per watt. However, COB LED has the upper hand here as it is more energy efficient and has a higher lumen capacity per watt ratio.
Current Capacity:
COB LED requires higher capacity sources, whereas SMD can work fine in smaller LED units.
Color-shifting feature:
COB LEDs aren’t for you if you wish to modify and play with different color spectrums. Whereas SMD lighting is perfect for light color variations as they come with red, green, and blue diodes.
4. Benefits and Drawbacks of COB LED
