Features

Comfortable lighting with dimming for scenes: Appropriate lighting and scene control based on specific environment or condition can not only provide better living situation, but also save energy consumption. You can enjoy a pleasant lighting environment by simply pressing a button.

Smart lighting with body detection: According to surveys, most lamps in offices without a worker are lighted over 70% of the office hours. The LED drivers of DDL series with built-in PIR detectors can automatically execute continuous illumination adjustment. Thus, secure, comfortable, and energy-saving smart lighting control can be achieved. Major parameters such as illumination and delay time can be varied on demand.

There are two setting modes to be used in smart lighting control. (1)Single mode (in Fig. 2 above): the output power of every LED driver in the DDL series is determined by the individual PIR detector. (2)Group mode (in Fig.2 under): every LED driver in the DDL series can share the outcome of other PIR detectors and offer the information to other lamps within the same group. Thus, all lamps in a group can be turned on simultaneously.

Complete control for systems or individuals: The LED drivers of DDL series with built-in DALI interface and PIR detectors can create the simplest smart lighting control system to date. Either a lighting network in a building or an individual lamp can be completely controlled by our products.

Automatic energy-saving with schedule control: By using the scheduling function, on/off or illumination of lamps at specified time can be controlled based on your schedule. Hence, target of energy conservation can be achieved automatically.

Superior energy conversion efficiency and power factor

Both requirements of “limited budget” and “uncompromising efficiency” can be satisfied concurrently. The LED drivers of DDL series can provide more …
