Living Room Lighting Environment: Precise Control Enabled by Intelligent Lighting Technology | Case Study

Create User:admin Create Date:2015-12-24 16:29:00

The Semiconductor Lighting Technology Research Center of Sun Yat-sen University (Guzhen) has established a DALI Lighting Experience Zone, which includes a reception area, a dining area and an open pantry. The design scheme is as follows:

Lighting and Light Source Design

The light sources used in the lamps are shown in the table below. The lighting control points in this experience area are as many as 26. To achieve more flexible and diverse regulation of the lighting environment, most of the lamp light sources adopt dual-color temperature dimming and color-tuning LED lighting sources.




Lighting Control Panel Design
To make lighting control more convenient and flexible, an 8-button lighting control panel is installed on the wall at the entrance, and an LCD touchscreen lighting control panel is mounted on the wall near the dining table.
In addition, a set of lighting control software is also installed on mobile smartphones or tablet computers.

Lighting Control System Design

The DALI lighting control system is adopted. The wiring structure of the DALI lighting control system is very simple; there is no need to pre-allocate power supply loops for the luminaires. All luminaires can even be connected in parallel to the same power supply loop.
During the wiring installation, it is only necessary to connect the DALI interfaces of all luminaire drivers and lighting control panels in parallel to the same pair of DALI buses to complete the circuit installation. The remaining lighting function configuration is entirely implemented by software and can be modified arbitrarily according to actual application requirements and personal preferences.





In the system design of this experience area, the designer has set the 8-button lighting control panel on the wall at the entrance to provide quick control for 8 scenes, realizing one-touch control of lighting scenes including Reading, Home, Entertainment, Reception, Dining, Leisure, Away (All Off), and Sleep (Only individual light sources remain at 1% brightness).



The LCD touchscreen lighting control panel on the wall near the dining table is configured with more comprehensive lighting control functions.
In addition to scene control, brightness adjustment, color temperature tuning, as well as independent and grouped on/off control of luminaires can all be easily implemented.

Personalized Lighting Control Configuration

Lighting control requirements are influenced by multiple factors, yet are mainly related to the nature of human activities and personal preferences. Even for the same activity, such as dining, some people prefer brighter lighting to clearly see the color and luster of dishes, while others favor dimmer light to enjoy a warm and cozy atmosphere. Therefore, lighting control should allow users to perform refined configuration according to their personal preferences at any time.


To this end, the system provides a lighting control application (App) that can run on smartphones or tablets.
With this application, users can not only achieve real-time lighting control, but also modify the lighting control functions of each button on the control panel and the parameter settings of various lighting scenes at any time as needed, which excellently meets the demand for personalized lighting control.
