LED Lighting - COBs, Engines, Modules

The LXK7-PW30-0012 is a light-emitting diode (LED) package powered by a module of 4 ballast resistors, which provides high-efficiency current control and thermal protection at a wide range of supply voltages. The package is designed to handle up to 30 Watts of power.

Application Field

This Package is suitable for many applications, such as retrofit lamps, wall packs, street lights, garden lights, and floodlights. The LXK7-PW30-0012 is especially suitable for high-bay and large area lighting. Its high power capabilities, combined with its thermal management designs, enable it to handle applications requiring high brightness and wide area illumination even in the toughest environmental conditions.

Working Principle

The LXK7-PW30-0012 works according to the CC/CV method and uses current control to deliver the maximum energy from a constant current source. The current control is achieved with the help of 4 ballast resistors located on the bottom of the package, which produce constant current when the supply voltage is at a certain level. A variable control parameter is used to set the output of the current, and it is connected in a circuit with the 4 ballast resistors. This variable control parameter is the duty cycle, i.e. how much time a certain current level is delivered, compared to the total cycle time.

The LXK7-PW30-0012 also has thermal protection, which is provided by a temperature sensor located on the bottom of the package. This temperature sensor will turn off the power if it detects that the temperature is too high, thus preventing any possible damage to the LED from overheating.

In addition, the LED package is designed in a way to optimize its light emitting efficiency by reducing the number of pins for the connecting wires and minimizing the total number of components. This reduces the total weight, number of components, and energy consumption, making it perfect for applications like high-bay lighting, which require high luminous efficacy and low energy consumption.

Conclusion

The LXK7-PW30-0012 LED package has many advantages in various lighting applications, including its wide range of supply voltages, high-efficiency current control, thermal protection, and optimized light emitting efficiency. It is especially suitable for applications requiring high brightness and wide area illumination even in the toughest environmental conditions.
