The Benefits and Drawbacks of COB LED
Benefits of COB LED
There is a lot of light as a result of the inclusion of several diodes.
* It consumes less energy while producing more lumens.
* The gadget is compact because of the constrained light emission zone. The lumen per square centimeter/inch has increased dramatically as a result.
* A single circuitry with only two connections is utilized to activate the many diode chips contained in COB LEDs. As a consequence, less hardware is required for each LED chip to function properly. Additionally, the heat produced by each LED chip may be reduced by lowering the component count and getting rid of the typical packaging for LED chip design.
* The overall temperature range of the complete assembly is less due to the very simple installation in an external heat sink. Things last longer and are more dependable when they are kept at a consistent temperature, which helps you save money.
* Efficiency is increased, and clarity is enhanced.
* It has a big focusing area since it can cover a sizable region with a single chip.
* Outstanding anti-vibration capabilities
The drawbacks of COB LED
* A well-designed external power supply. This happens because the diodes need a constant current and voltage to function properly.
* A good heat sink design is crucial. If the heating element is not positioned correctly, overheating will cause the diode to fail. Huge amounts of heat are produced as a result of the very concentrated light waves that are radiated from a small space.
* Cob chipped lighting fittings are less repairable. This is so that the complete COB led may be replaced with a newer one in the event that one of the COB's single diodes is broken due to a mechanical error. However, if an SMD LED dies, it is easy to replace it and restore operation at a reduced cost.
* There is a little color variety.
* Costlier than SMD chips.
Utilizations for COB LED
From domestic to industrial utilities, COB LEDs have a broad variety of applications, some of which include:
* Street lighting, high-bay lighting, downlights, and high-output track lights would all largely employ COB LEDs as solid-state lighting (SSL) replacements for metal-halide bulbs.
* Due to their wide-angle beam, they are suitable in LED lighting fixtures for installation in living rooms and large halls.
* Areas like playgrounds, gardens, or enormous stadiums need a lot of lumens at night.
* Other uses include the replacement of fluorescent lighting, LED lights, light strips, smartphone camera flash, and basic illumination for hallways and corridors.
Conclusion
Lighting applications are increasingly using COB LEDs as designers learn more about their benefits over conventional standard LEDs. For any led light application structure, it's challenging to ignore them because of:
* Their capacity to fit more LED sources in a smaller space, producing more lumens
* Their improved capacity to transfer heat to a heat sink
* Their broader range of vision
* They suffer less light loss
* Due to their simpler structure, they have reduced failure rates.
The most latest and cutting-edge technology available today is COB LEDs. Simply put, they outperform the older LED technology presently used in the majority of trade show lighting in terms of brightness, energy efficiency, and light quality.
