Audax chose the Lumileds LUXEON 3535 HV LED for several

reasons: high reliability relative to comparable products in

the market competitive pricing and the ability to deliver the

required voltages and lumen output for over 30 kinds of

fixtures.

Benefits

The residential consumer lighting market is extremely cost

sensitive. Since the driver represents a considerable portion

of LED fixture cost, the use of high voltage LEDs represents

a compelling solution—the compatible high voltage drivers

themselves are less expensive than standard drivers.

Furthermore, the small size of the high voltage drivers simplifies

the overall design process and enables more compact fixtures.

Lumileds offers the LUXEON 3535 HV LEDs in 24V and 48V

formats and have a comprehensive ecosystem of drivers

available (which can be found at lumileds.com/designtools).

The result is compact and cost efficient fixture design and

faster time to market of LED fixtures.

“Audax Electronics chose the LUXEON 3535 HV LED to use in its modules based on

its high reliability, ability to achieve a low cost point for consumer lighting, and also

the high lumens and overall performance offered by the

48V product.”

Results

For the residential market in Brazil, Audax’s residential lighting

products signify a successful departure from traditional

CFL-based lighting. Using Lumileds LUXEON 3535 HV LEDs

in conjunction with high voltage drivers designed in-house,

Audax was able to produce standard boards which are used

in over 30 different kinds of fixtures such as wall packs, wall

sconces, bollards and pendants. “Audax Electronics chose

the LUXEON 3535 HV LED to use in its modules based on its

high reliability, ability to achieve a low cost point for consumer

lighting, and also the high lumens and overall performance

offered by the 48V product,” said Rafael Grassi, Director of

Audax Electronics. The high voltage driver design and high

lumens produced by the LUXEON 3535 HV 48V ultimately

resulted in a design that was compact yet powerful, making

these residential LED fixtures competitive with their CFL

predecessors.
