摘要： A light generating device (20) comprises: - an input for receiving a DC input voltage (Vin) of varying magnitude; - a controllable current source (40); - a switch matrix (30) comprising a plurality of controllable switches (S1-SN); - a plurality of n LEDs (D1, D2,... Dn) connected to output terminals of the switch matrix (30); - a controller (50) controlling said switches and controlling the current generated by the current source dependent on the momentary value of the DC input voltage (Vin). The controller is capable of operating in at least three different control states. In a first control state all LEDs are connected in parallel. In a second control state all LEDs are connected in series. In a third control state at least two of said LEDs are connected in parallel while also at least two of said LEDs are connected in series.

摘要： A method for manufacturing a flooring product with integrated circuitry, comprising the steps of providing a plurality of pieces (6), stacking said pieces on top of each other, displaced in relation to each other to form an offset stack (10), and compressing said offset stack to form said flooring product. The method further comprises arranging flexible circuitry (7) on an upper surface of at least one piece, so that, when said pieces are stacked, a first portion (7a) of flexible circuitry on the at least one piece is exposed, said first portion (7a) including circuitry for interacting with the environment. By arranging the circuitry in the flooring during such a manufacturing process, a flooring product is achieved where only a portion of the circuitry is exposed, and another portion is embedded in the flooring. This allows for exposing those parts of the circuitry that are adapted to interact with the surrounding environment, such as optical components, pressure sensitive components, acoustic components, etc.

摘要： The present invention relates to a harmonic compensation circuit for compensating at least the third harmonic in the input current (I
mains ) drawn by an LED light source (1) from a mains voltage supply (2), comprising: a signal input (21, 22) for receiving a first input signal proportional to the input voltage (V
in ) of said LED light source (1) and a second input signal (V
sh ) proportional to the LED current (I
LED ) of said LED light source (1), a signal output (25) for outputting a compensation current (Icomp), a processing unit (24a, 24b) for comparing said second input signal (V
sh ) to a reference signal (V
Rb , V
R7 ) and for generating said compensation current (I
comp ) based on said comparison, the sum of said compensation current (I
comp ) and said LED current (I
LED ) being proportional to the input voltage (V
in ) of said LED light source (1) and said compensation current (I
comp ) being provided for minimizing at least the third harmonic in the input current (I
mains ) drawn by said LED light source (1) from said mains voltage supply (2).-
