A COB light is a type of LED light, with COB standing for Chip-On-Board. COB lights are essentially an array of LED chips that are tightly packed together and bonded to a substrate such as silicon carbide. In effect this creates one large LED chip that has excellent uniformity of brightness, thus making it ideal for photographers and filmmakers.
When most people think of LEDs they probably think of the small singular lights that they experimented with at school when learning about electronics. Those types of singular round LEDs are called DIP LEDs, or Dual In-Line Package. They are also the kind of LEDs you might find in a control panel to indicate when a switch is on or off. DIP LEDs are cheap, but they are bulky and not very powerful.
The Godox SL-60 COB light.
Taking a 10mm x 10mm square LED array as an example, you would only fit 9 DIP LEDs on the square. You would fit 342 COB LEDs in the same space, though, so you can instantly see the advantage in a light that is designed for studio photographers or filmmakers. A much brighter light source can be created using a much smaller light.
If the light is to appear in a shot itself, a COB appears as a single light source, where older LED panels that were constructed of hundreds of DIP LEDs all lined up, would often show a zebra pattern, along with far less panel uniformity.
COB lights are also relatively simple in the way that they work, and this created a robust and reliable design. With a large array of older DIP LEDs, each individual LED would have its own circuit to power it. A COB only has a single circuit, with the whole COB panel acting as a single light, despite containing multiple small LED panels.
One of the downsides to a COB light, especially in a studio scenario, is the heat that is generated. With such a huge amount of light energy created in a small area, the heat is very localized and requires passive and active cooling. Passive cooling in COB studio lights is done by huge heatsinks that surround the front-mounted COB panel. You can see it clearly in the photo of the Godox SL-60.
Active cooling if often also necessary, and this means there will be a fan inside the head. In a stills photography studio a fan is a small problem, but they can be an issue for filmmakers if you need to record sound. A single COB light is unlikely to cause problems, but if you had a huge number of them it would become something to be aware of. Also worth noting is that the cheaper the lights you buy, the cheaper and noisier the fans will be.

What is flip chip COB?
The flip chip COB is a real chip-level package, with no need to hit the wire, and the physical space size is only limited by the size of the light-emitting chip. Flip-chip COB, as an upgrade of COB, is based on the advantages of COB such as ultra-small dot pitch, high reliability, and non-glare surface light source. Further, improve the reliability, simplify the production process, better display effect, perfect near-screen experience, and realize the real chip-level pitch.
What is the difference between a traditional COB chip and a COB flip-chip?
1. Only flip-chip COB can realize the real chip-level pitch and reach the level of Micro LED. This is because, from the perspective of LED chips, Flip-Chip does not need to hit the wire, breaking the pixel pitch limit of regular chips and solving the metal migration problem in regular LEDs.
2. At the same time, each pixel unit has 6 metal bonding surfaces, which effectively solves the problem of bad wire breakage caused by dummy wire bonding and further improves the reliability. From the packaging point of view, the Flip-Chip COB package is a true chip-level integrated package with wireless bonding, and the physical space size is limited only by the size of the light-emitting chip, allowing for higher pixel density.
3. In terms of display performance, the Flip-Chip has a smaller area on the PCB board and the duty cycle of the substrate increases. It has a larger light-emitting area and can render darker black fields, higher brightness and higher contrast.
4. Present HDR level display effect. And there is no welding wire link, which effectively simplifies the production process and reduces the equipment investment cost. With the expansion of industrial scale, the product cost will be greatly reduced, especially when the dot pitch is less than 1.0mm, it will have a cost-competitive advantage.

Getian High CRI COB LEDs feature single-channel dimming and High CRI COB LEDs feature single-channel dimming and dual-channel color adjustment options, as well as excellent color rendering with high CRI (95+) and R9 (90+) values, making them the ideal light source for even the most demanding applications.
We all know that LEDs last longer, use less energy, and don't produce as much heat as incandescent bulbs. However, there are subcategories of LEDs, such as Cree or COB LEDs, which offer users the advantages of regular LEDs, so what is the difference when looking at Cree versus COB LED lights?
What is the difference between Cree and COB LED lights? The differences are minimal, but there are enough differences to choose between them.
What is a Cree LED?
What is the difference between Cree and COB LED lights? Cree LEDs are simply LED lights that utilize Cree chips. There are many reasons why the lighting community praises the chips used by Cree. However, the most common reasons include high performance output, longevity and stability. You can look at the chips to see if they are Cree.
Cree chips use square chips that are divided into rectangles. cree chips can provide 370 lumens of light to your LED, which is another reason why these chips are so popular. You'll find Cree chips in a number of different places, such as emergency lights, portable lighting, automotive manufacturers, and outdoor and indoor lighting. This means that Cree LEDs are LEDs that use Cree chips.
What is a COB LED?
COB LEDs are chip-on-board LEDs. these LEDs have multiple diodes, each with its own chip to control it. However, the diodes and chips are placed close together on a panel, thus producing a single light source. The best way to think about this is in terms of Light Bright. Remember those toys we played with as kids? When you placed them on a panel, their colored pegs would light up. You can place a colored peg on the panel and get a small light source. Insert multiple pegs next to each other and you will get a piece of light.
Chips and Panels
To understand the difference between Cree and COB LED lights, we should understand the difference between a chip and a panel. The chip powers and controls the LED diode. Think of a diode as a small light bulb. A COB LED has many diodes in a panel, creating a single diode that looks much larger.
This large size allows the COB LED to produce light that covers a wide area. On the other hand, the chip controls the diode, tells it how brightly it emits light, and is also able to change the color (if the diode is able to change color). The question is, if COB LEDs have chips, and Cree is the chip brand, can't you just have Cree COB LEDs? The short answer is yes.

In the realm of machine vision, infrared (IR) light-emitting diodes (LEDs) play a pivotal role in enhancing the capabilities of imaging systems. Unlike visible light, which is constrained by its shorter wavelengths, IR LEDs operate in a spectrum that allows for deeper penetration into various materials, enabling the detection of defects that are often invisible under standard lighting conditions. This unique property makes IR LEDs invaluable in industrial applications where precision and reliability are paramount.
Understanding Infrared Light
Infrared radiation encompasses a broad range of wavelengths from approximately 780 nm to 1 mm, with the near-infrared (NIR) range, specifically from 780 nm to 3000 nm, being particularly relevant for machine vision applications. IR light's longer wavelengths facilitate its ability to penetrate materials such as glass, plastics, and textiles, thereby revealing internal flaws or surface defects that might otherwise go unnoticed. This characteristic is especially beneficial in environments with challenging lighting conditions, where visible light can create noise or reflections that obscure critical details.
Advantages of IR LEDs in Machine Vision
The integration of IR LEDs into machine vision systems offers several advantages:
Reduced Surface Reflection: IR light generates fewer surface reflections compared to visible light, allowing for clearer imaging of textured or shiny surfaces.
Non-Disruptive Inspection: Since IR radiation is invisible to the human eye, it can be employed in settings where visible light would interfere with operations or distract personnel.
Versatile Applications: From inspecting printed materials to detecting flaws in opaque objects, IR LEDs can be tailored for a variety of inspection tasks.
The advent of UV (ultraviolet) light-emitting diodes (LEDs) has revolutionized the field of 3D printing, significantly enhancing the efficiency, quality, and versatility of additive manufacturing processes. As industries increasingly adopt 3D printing for prototyping, production, and custom fabrication, the integration of UV LED technology has emerged as a game-changer. This introduction explores the fundamental principles of UV LEDs in 3D printing, their benefits, applications, and the future landscape of this innovative technology.
The Role of UV LEDs in 3D Printing
UV LEDs serve a critical function in the curing process of photopolymer resins used in various 3D printing technologies, particularly Stereolithography (SLA) and Digital Light Processing (DLP). These technologies rely on liquid resins that harden when exposed to specific wavelengths of UV light. The ability of UV LEDs to emit precise wavelengths allows for rapid curing and solidification of the resin, enabling the creation of intricate designs with high fidelity.
How UV Curing Works
The process begins with the application of a liquid photopolymer resin onto a build platform. As the printer layers this resin according to a digital model, UV LEDs are activated to emit light that initiates a chemical reaction within the resin. This reaction causes the polymer chains to cross-link, transforming the liquid resin into a solid structure almost instantaneously. Unlike traditional curing methods that rely on heat or air drying, UV curing offers several advantages:
Speed: The curing process occurs within seconds, allowing for faster layer-by-layer construction.
Precision: The controlled emission of UV light leads to uniform curing across complex geometries.
Reduced Heat Generation: UV LEDs produce minimal heat compared to conventional curing lamps, making them suitable for heat-sensitive materials
