The present disclosure is directed to inventive methods and apparatus for lighting control and for providing effects upon activation/deactivation. For example, various methods and apparatus are described for controlling various selected properties of light emitted by an LED-based lighting unit () with multiple LEDs () using, for example, a dimmer switch () and/or a predefined sequence of energizing LEDs.

Methods and apparatus for controlling illumination of a multiple light source lighting unit

The present invention relates to assisting a user in selecting a lighting device design by providing a lighting device design based on a model or image of a lighting device design (e.g. the user uploading an image of an existing lighting device in his/her home). The lighting device design of the model or image is analyzed in order to determine a lighting device design related variable (e.g. type, shape or color of lighting device design). This variable is then used to select a lighting device design from a set of lighting device designs (e.g. to select a lighting device design of the same color, from an electronic catalogue of lighting device designs); or to generate a lighting device design (e.g. to generate a lighting device design that is a copy of the lighting device design in the image, only smaller and in a different color). The invention further includes a system and computer program product for implementation of this method.

Assisting a user in selecting a lighting device design

Disclosed is a lighting unit () that utilizes sensor data to select a fade-in or fade-out profile for one or more light sources (). The lighting unit includes a clock module (), an ambient light level sensor (), and a controller (). The controller receives ambient light level data from the ambient light level sensor and time of day data from the clock module, and utilizes the received information to automatically select a fade-in or fade-out profile. The controller can also use the received ambient light level data to calibrate the clock module.

Apparatus for controlling lighting parameters based on time of day and/or ambient light conditions and related methods

The present invention relates to assisting a user in selecting a lighting device () design through receiving an image of a scene, e.g. the user taking a picture using his/her smartphone of his/her living room () and analyzing this image in order to select or generate a lighting device () design. The analysis can comprise determining the presence of a pattern, material or color in the scene and a lighting device () design can be selected (e.g. from an electronic catalog) that comprises a similar pattern, material or color. As another example, a lighting device () design can be generated to match such a pattern, material or color. The invention further comprises a system and computer program product for implementation of this method.
