  • Patent number: 11287727
    Abstract: Introduced here are light sources for flash photography configured to produce high-fidelity white light that is tunable over a broader range of correlated color temperatures (CCTs) than conventional flash technologies. The light source can include multiple independently controllable color channels representing illuminants (e.g., light-emitting diodes) of different colors with varying degrees of saturation. Operating collectively, the multiple color channels can produce a high spectral quality white light corresponding to different CCTs (e.g., “warm” white light having a red hue, “cool” white light having a blue hue). Operating independently, these same color channels can be pre-flashed in a variety of prescribed sequences to probe the spectral characteristics of a scene, thereby allowing for an enhanced, spectrally matched white flash as well as collecting per-pixel reflectivity data that can be later used in during post processing of the captured image.

  • Patent number: 11291094
    Abstract: A LED driving circuit (20) is for driving at least two LED segments (22, 24) of different color or color temperature, using an input current which has a current ripple amplitude. The LED driving circuit (20) comprises an input to receive the input current; an output to connect to the at least two LED segments (22, 24); and a current distributing circuit which provides the input current to a single one of the two LED segments when the current is at a peak portion, wherein the current distributing circuit is adapted, when providing the input current to a single one of the two LED segments during the peak portion, to provide the input current to the single one of the two LED segments alternately, and splits the input current into two non-zero currents for different LED segments when the current is in a trough. When all current is provided to one LED segment, the light conversion efficiency is lower than when two segments are driven with lower current.

  • Patent number: 11248780
    Abstract: A LED driver comprises two output contacts (310, 311) and an additional contact (312) which enables detection of connection of the LED driver to a LED module (301). The LED driver has a normal current regulating mode and an open circuit protection voltage regulating mode. The LED driver is switched from the voltage regulating mode to the current regulating mode in response to the detection of connection of the LED module. This enables a LED module to be connected to the LED driver while it remains powered, in particular because the LED driver is placed in a voltage regulating mode prior to connection to the LED module.
