Embodiment Construction

[0022] figure 2 An arrangement 200 of an example concept comprising a switch unit 210 , a controller 220 and two or more light sources 240 is schematically illustrated. For clarity and simplicity of description, the one or more light sources 240 are described as including a first light source 240a and a second light source 240b, although the two or more light sources 240 may include further light sources. The two or more light sources 240 may be arranged as one or more light elements such that each light element includes one or more of the two or more light sources 240 .

[0023] The arrangement 200 provides a logical structure and its elements may be provided as units or parts of a single device, or as units or parts of one or more devices. In other words, the switch unit 210 and the controller 220 are logical entities, which may be implemented in one or more devices, and two or more light sources 240 may be connected to one or more devices including the controller 220 or p...

Abstract

A method is provided for controlling the operation of a first light source of a first color and a second light source of a second color, the method comprising receiving an input control signal having a user controllable duration, responsive to the entirety of the single input control signal The first and second light sources are turned on or off for a duration not exceeding a first predetermined threshold, and the first and second light sources are changed in response to a duration of the input control signal exceeding a second predetermined threshold not less than the first predetermined threshold. A characteristic of the light provided by the light sources, the change of which depends on the duration of the input control signal, and the change comprises an adjustment of the ratio between the light intensities of the first light source and the second light source.

Description

technical field [0001] The invention relates to the control of two or more light sources. In particular, the present invention relates to apparatus and computer programs for controlling the operation of two or more light sources, such as two or more light emitting diodes (LEDs), two or more fluorescent lamps, two or multiple high intensity discharge (HID) lamps, two or more incandescent lamps, etc. Background technique [0002] figure 1 An example conceptual switch arrangement 100 known in the art is schematically illustrated. The switch arrangement 100 comprises a switch unit 110 , a controller 120 and a light source 140 . The switch unit 110 includes a user-operable button or a corresponding arrangement configured to provide an input control signal to the controller 120 in response to a button being pressed, the input control signal having a duration substantially corresponding to the button being pressed. duration. Therefore, the controller 120 is configured to contr...
