LED holder has DC/DC constant current LED driver functionality

TE Connectivity has developed the Lumawise Drive LED holder Type Z50 – DALI-2 series for more compact track and spot lighting.

The Lumawise Drive LED holder Type Z50 – DALI-2 series for chip-on-board (CoB) LEDs is designed for 48V DC input and incorporates DC/DC constant current LED driver functionality into a low profile LED holder.

The Lumawise Drive LED holder Type Z50 – DALI-2 series integrates the driver into the same form factor as TE’s 50mm-diameter Zhaga-inspired range of Lumawise LED holders for CoB LEDs. Until recently, most LED drivers were housed in a box, often larger than the light fixture itself, mounted to the side of the luminaire and remote from the CoB light source. This configuration requires wiring between the light source and driver, creating design and manufacturing complexity. The Lumawise Drive LED holders work with a range of readily available 48V constant voltage power supplies, meaning powering multiple fixtures off a single power supply is now possible.

DALI (Digital Addressable Lighting Interface) lamp fixtures are intelligent, dimmable and can be controlled, monitored and maintained using a two-wire global IEC 62386 open standard communication protocol. A variety of DALI-compatible fixtures are available globally from various manufacturers.

The Lumawise Drive LED holder joins the Lumawise Drive LED holder Type Z50 On/Off series and 0 to 10V dimmable series. All configurations are available in 350, 500, 700 or 1050mA constant current output and a typical forward voltage of 36V DC.

TE Connectivity is a global technology and manufacturing leader that for more than 75 years has provided connectivity and sensor products that have been proven in the harshest environments, have enabled advancements in transportation, industrial applications, medical technology, energy, data communications, and the home. TE has 80,000 employees, including more than 8,000 engineers, working alongside customers in approximately 140 countries.
