A CoB LED (or chip-on-board LED) is a single device that consists of many LED chips installed on a thermally efficient substrate beneath a homogeneous phosphor coating.
Anyone who travels through a store or house with recessed or track lighting will most likely be illuminated by a chip-on-board LED (CoB). CoBs are frequently used because they produce a brilliant white light from a small light source and are extremely efficient in a wide range of applications.
The term CoB (chip-on-board) refers to how the LED unit is built. The following are the fundamental components of white CoB LEDs:
A power supply that provides the electricity to power the LED. The chip or die that emits light. A phosphor coating that transforms blue light to white light. The phosphor’s chemical composition is adjusted to emit light of a certain color temperature.
A CoB LED is a single device that consists of many LED chips put on a thermally efficient substrate, or board. Each chip is a bare die, which means it lacks its own lead-frame, phosphor coating, and lens.
This allows the chips to be put very close together on the substrate. Because the LED chips are so close together, high intensity or light density may be emitted from a smaller area than is feasible with single packed LEDs. To convert, the CoB LED maker next applies a homogeneous phosphor coating to the whole array of chips.
A single CoB LED can have hundreds of chips arranged in a dense array. This dense array allows a CoB LED to emit more light from a smaller area than is typically feasible with a packaged LED array.
Using a single LED can simplify design and product while also giving optical benefits for consistent light and efficient optics. Because the CoB LED just requires a single two-wire power source to power the full array of chips, electrical design is simplified. In the image of LUXEON CoB Core Range goods above, the positive and negative terminals on a CoB LED are plainly apparent.
In contrast, an array of packed LEDs necessitates the routing of individual power supply lines on the PCB to each LED. When a CoB LED is used instead of an array of packaged LEDs, production is simplified since the number of units to be soldered to the board is reduced.
A variety of optics, often reflectors, can be used with CoBs of various sizes to decide the direction and breadth of the beam, as with a spot or flood light. Finally, the color of a CoB LED may be more constant since a single phosphor coating is applied to the whole array of chips, whereas each LED unit in a packaged LED array has its own phosphor coating.
The Global COB LED Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Sharp Devices Europe (SDE) has introduced a new line of high-efficiency Mini and Mega Zenigata COB LEDs with improved hot lumen performance. Sharp Devices Europe (SDE) has introduced a new line of COB LEDs with outputs ranging from to. Sharp’s new HD6 and BF6 family LEDs, which are available in the popular Mini and Mega Zenigata footprints, are among the most efficient on the market.
Sharp’s die-level technical advancements, along with the global technology giant’s packaging knowledge, enabled this latest wave of efficiency gains. Sharp has secured backwards compatibility and eased mechanical integration for its customers by preserving the popular Mini and Mega Zenigata form factors.
The Mini and Mega Zenigatas are available in a variety of color temperatures as well as Ra80 and 90 variants. They can provide great color rendering performance across a wide range of applications thanks to the efficiencies these new models achieve.
The new COB LEDs are especially notable for their better hot lumen performance. Most LED manufacturers specify cold performance, however as LEDs reach operational temperatures in the luminaire, their intensity drops. Under real-world conditions, the new Mega and Mini Zenigatas produce more power.
North America
The North American market, particularly the USA, will be one of the prime markets for (COB LED) due to the nature of industrial automation in the region, high consumer spending compared to other regions, and the growth of various industries, mainly AI, along with constant technological advancements.
The GDP of the USA is one of the largest in the world, and it is home to various industries such as Pharmaceuticals, Aerospace, and Technology.
