Abstract: The present invention proposes a method, apparatus, controller and system for controlling illuminance. Specifically, the system comprises at least one light source, each of the at least one light source comprising a plurality of light modules and each of the plurality of light modules being adjustable independently; and a controller configured to control the illuminance of a target area in the lighting system. One or more light modules associated with the illuminance of the target area are selected from the at least one light source based on the position relationship between the at least one light source and the target area and a lighting distribution of each of the at least one light source. Then, at least one of the selected one or more light modules is adjusted to meet a certain requirement for the illuminance of the area. As a result, personalized lighting for an open area is effectively achieved.

Abstract: The application discloses an illumination apparatus comprising: a light source configured to generate light; a detector configured to detect the posture of an object within a time period and generate a plurality of signals corresponding to this time period; and a processor configured to determine the status of the object within the time period, based on the plurality of signals, and adjust the light source to generate light corresponding to the determined status of the object.

Abstract: The invention provides an illumination apparatus and a method of generating light by the illumination apparatus. The illumination apparatus comprises a light generation unit, configured to generate light having a color temperature in the range of [a first color temperature, a second color temperature]; and a controller, configured to control the light generation unit to generate light having a color temperature changing from a third color temperature to a fourth color temperature over time, wherein the third and the fourth color temperatures are in the range of [the first color temperature, the second color temperature]. The illumination apparatus of the invention could generate light having a changing color temperature over time, for example a color temperature changing from a less preferred color temperature to a preferred color temperature.

Abstract: This invention provides an illumination apparatus and an illumination method. The illumination apparatus comprises: a first light source for illuminating a first area; a second light source for illuminating a second area; a first measuring unit for measuring the illuminance of the first area; a second measuring unit for measuring the illuminance of the second area; and an adjusting unit for adjusting at least one of the first light source and the second light source to make the contrast ratio of the measured illuminance of the first area to the measured illuminance of the second area change gradually from a first predefined value to a second predefined value lower than the first predefined value during a first predefined duration. In this way, the relative higher contrast ratio (i.e. the first predefined value) enables the users to improve their work efficiency and the relative lower contrast ratio (i.e. the second predefined value) allows the users' eyes to be comfortable.

Abstract: The invention relates to illumination, especially to a grid for illumination apparatus. This invention provides a grid (100) for attenuating electromagnetic radiation from a light source. The grid comprises a plurality of baffles (110), each baffle being electro conductive, wherein the plurality of baffles are configured to form a plurality of cells (120), each cell being formed as a waveguide so as to attenuate the electromagnetic radiation from the light source. In this way, the electromagnetic radiation from the light source can be reduced or prevented so as to decrease the danger to users.
