COB, referred to as Chip On Board, is a LED lighting module, which is composed of substrates, LED chips, wires, and phosphor. COB LED lighting has become a reliable, efficient and cost-effective lighting solution for commercial, residential, and industrial applications. The LF2D-EN21F-2W-450, produced by Lumileds, is an advanced COB LED that has numerous advantages in comparison to traditional lighting sources.

The LF2D-EN21F-2W-450 is composed of an array of LEDs which are encapsulated in a ceramic-metal package. Due to its 2 Watt wattage and an embedded driver, the LF2D-EN21F-2W-450 can easily deliver lighting with precise illumination. The LEDs are arranged in a single row and deliver a consistent flux, which helps in light distribution. In comparison to normal SMD LED lamps, the COB LED lams last much longer, up to 50,000 hours. This makes it an excellent choice for applications such as outdoor illumination, signage, and decorative/architectural lighting.

The other key advantage of COB LEDs like the LF2D-EN21F-2W-450 is their high lumen-per-dollar ratio. With an enhancing chip efficiency, the luminosity emitted by this COB LED is greater than many SMD LEDs. As a result, the LF2D-EN21F-2W-450 offers up to 86 lumen-per-watt efficiency, thus helping to reduce overall energy consumption. It also has a wide operation range between 2.85 to 4.4VOLTS, allowing for support of many lighting designs.

In terms of working principle, the LF2D-EN21F-2W-450 follows the same principles as that of traditional LED lighting. It consists of LED chips, substrates, and phosphor. The LED chips of this COB LED are mounted on a substrate and connected to the driver. The protective phosphor is then inserted between the semiconductor layers of the LED chips. When the current is passed through the LED chips, an electrical energy is converted into light energy. The emitted light then exits through phosphor, thus producing the desired wavelength of light.

In addition, the LF2D-EN21F-2W-450 also has several safety features. Its ESD immunity of up to 10KV helps to protect it from professional high electrostatic voltage. Also, the die temperature and current are monitored, further boosting its safety quotient. This ensures that the COB LED does not emit light beyond its safety limits and does not get bounced off due to excessive temperatures.

To conclude, the LF2D-EN21F-2W-450 is an excellent COB LED that offers numerous advantages to its customers in terms of efficiency, lumens-per-dollar, and safety. In terms of application fields, it has proved to be an excellent option for outdoor illumination, signage, and decorative/architectural lighting. By providing precise illumination and long lifespan, this COB LED has made life much easier for lighting designers, thus making it one of the leading LED lighting solutions in the market.
