LED lighting has become a more economical and efficient way to light up a variety of indoor and outdoor applications. The usage of LED lighting has been made more accessible and affordable to customers thanks to COBs (Chip-on-Board) and the engines built into them. One engine, the LMH020-0850-35G9-00000TW, has been developed to be used in a wide variety of lighting applications.

Application Field

The LMH020-0850-35G9-00000TW engine can be used in a variety of lighting applications, from lighting up residential and commercial properties, to stage and event lighting, and even in automotive lighting. Its package is made up of eight strings of LEDs, which each have a forward voltage of 3.5-4.4V and a forward current of 350mA per string. Combined, these parts deliver up to 20W LED lighting output.

The engine is also designed to work with different light source packages for different options. It has the ability to work with four 7.5W light source packages with three LEDs each, four 8.5W packages with four LEDs each, or two 10.7W packages with five LEDs each.

This makes the engine perfect for a variety of applications, including chandeliers, downlights, accent lighting, spotlights, and many more. The engine also has a high-CRI version available, making it suitable for applications that require accurate color rendering, such as retail and hospitality.

Working Principle

The LMH020-0850-35G9-00000TW engine works using two integrated circuits: a boost converter, and a dimmable LED driver. The boost converter supplies power to the LED driver, which in turn controls the current flowing through the LEDs. The dimming voltage for the driver is controlled by a 0-10V dimming signal, making the engine dimmable.

The engine also has an integrated over-voltage protection circuit, an over-temperature protection circuit, and a protection circuit for the dimming signal. These circuits ensure that the engine runs safely and reliably, and that it does not overheat or become short-circuited.

The engine also contains a primary-side feedback circuit for the boost converter, which ensures that the power delivery is accurate and reliable. This circuit ensures that the output of the boost converter is always consistent, even as the input voltage changes.

Conclusion

The LMH020-0850-35G9-00000TW engine is an efficient and reliable LED lighting solution. Its package is capable of delivering up to 20W LED lighting output, and it has the flexibility to work with a variety of light source packages, making it suitable for a wide range of lighting applications. Its integrated over-voltage protection circuit, over-temperature protection circuit, and dimming signal protection circuit ensure that the engine runs safely and reliably.
