Philips Fortimo HBMt Gen 3 System Design In Guide 13

Controllability

Default dimming protocols

The Fortimo LED HBMt Gen3 module is dimmable with a range of integrated light

control options.

• Adjustable Output Current

• Constant Light Output

• 1-10 V, AmpDim, DALI and Dynadimmer dimming

Specic features will depend on the Philips Advance LED driver system selected

(Tables 2-3). Please visit www.philips.comledsystemsna for complete information

on the integrated light control options available in the Xitanium product range.

Constant Light Output

There are minimum light level requirements for public lighting. In order to

compensate for lumen depreciation, which occurs in all light sources over time, the

lighting design is often over-lit at the beginning of the source’s lifetime.

It is possible to deliver energy savings by avoiding over-lighting and still ensuring the

minimum expected light level over the lifetime of the module if the Constant Light

Output (CLO) feature in Xitanium Programmable drivers is used.

The CLO feature uses a predictive algorithm to increase the output current to the

module over the specied lifetime of 50,000 hours

. As the current increases, the

energy consumption also increases. The CLO feature can be combined with other

dimming protocols for even greater energy savings.

Programming CLO in Fortimo LED High Brightness Module Gen 3 will ensure

minimal light levels without wasting energy in the beginning of module’s life.

Please use Table 15 to program the CLO curve for Fortimo LED HBMt Gen3.

Note: Although it is technically possible to dim Fortimo LED HBMt Gen3 modules

below 100mA, Philips does not specify product performance for modules operating

below this current.
