LED Lighting - White

Light Emitting Diode (LED) technology has quickly gained popularity for many lighting applications, especially for its energy efficient advantages and long lifetime. The combination of the SPHWH2L3D30CD4VMM3 LED driver and LED from Philips Lumileds is an example LED lighting system that is suitable for many lighting applications.

What is SPHWH2L3D30CD4VMM3?

The SPHWH2L3D30CD4VMM3 is a high-efficiency LED driver developed by Philips Lumileds. It is composed of a highly integrated AC/DC isolated boost power supply and a PWM dimming controller. It is designed to drive a Lumileds Luxeon Rebel based LED solution. Compared to conventional lighting solutions, the SPHWH2L3D30CD4VMM3 has higher efficiency, more reliable and longer lifetime.

Application Field

SPHWH2L3D30CD4VMM3 is primarily used for white LED lighting applications. It is suitable for applications such as commercial illumination and display cases, home decorative lighting, automotive headlights, backlighting and parking lot lighting, and many others.

Working Principle

The SPHWH2L3D30CD4VMM3 LED driver works based on a boost topology architecture. It converts a wide range of input voltage into a high-power LED forward voltage that is higher than the LED forward voltage. With the LED connected to the driver, the high-power LED forward voltage can receive the input source and draw out the power to achieve the desired LED output power.Additionally, the PWM dimming controller is an ASIC controller. It is used to control the dimming of the LED and regulate the output current. The PWM dimming controller is capable of supporting different dimming strobe types, such as phase shift, on/off or phase cut, or resistive PWM dimming.

Conclusion

The SPHWH2L3D30CD4VMM3 LED driver has many applications in the field of white LED lighting. It has a high-efficiency boost topology and is capable of driving a Lumileds Luxeon Rebel based LED solution, while providing excellent dimming control with multiple dimming strobe types. The SPHWH2L3D30CD4VMM3 LED driver is a great solution for many white LED lighting applications.
