AW2214 Application Field and Working Principle

The AW2214 is an LED COB (chip-on-board) product specifically designed to be used in LED lighting applications, such as streetlights, downlights and track lights. It is an important part of the LED lighting system, and it is necessary to understand its application field and working principle.

Applications

The AW2214 is designed for general lighting applications such as streetlights, downlights and track lights, both indoor and outdoor, including environments subjected to external weather conditions. The AW2214 is also suitable for commercial lighting with high requirements for light uniformity, color consistency and service life.

The AW2214 is specifically designed for low profile and narrow space applications such as retail and residential lighting, pathway lighting, and outdoor sign lighting, where space is limited. The AW2214 is even capable of being used in luminaries in which the AW2214 is the only light source.

The AW2214 product is composed of 22 die of 0.5W down chip (LED) packaged together into a 20mmx14mm cob module. It has a superior lumen output of 1065 lm at 1500 mA, and a color temperature of CCT 2700K. The AW2214 has a slight advantage over other models because its die is connected in series and its cooling system is independent.

Working Principle

The working principle of AW2214 COB (chip-on-board) is based on the production of light from the electrical current flowing through diodes. The diodes are placed on an aluminum-coated substrate with high thermal dissipation ability. The aluminum substrate has embedded electrical tracks that connect the diodes to a voltage source (usually a secondary winding of a transformer).

The AW2214 consists of a total of 22 LED die, each of which can be individually activated and powered. When the LED die is connected in series, one LED will activate another LED and so on until all 22 LED die are activated and can produce light. The heat generated by driving the LED die emanates from the aluminum-coated substrate and is dissipated by the simple cooling fins.

In addition, an optical lens is used to shape the light from the AW2214 COB, giving it better uniformity. The lens can also be used for directional applications, reflecting the light in a specific direction. The beam angle of AW2214 can be also changed by changing the lens type.

Overall, the AW2214 is an efficient and cost-effective LED cob module. Its high lumen output, excellent thermal management, and small form factor makes it suitable for a variety of lighting applications. Not only can it be used in a wide range of lighting applications, but its light quality is excellent and its color consistency is outstanding.
