    Abstract: The present invention provides an extension to a standard N-bit digital pulse width control method which can discriminate 2N discrete pulse widths per pulse cycle. The present invention provides a method and apparatus that can modulate the pulse widths over a period of 2M pulse cycles in which each pulse cycle can have its own pulse width or respective duty cycle. The resulting time averaged or effective pulse width therefore can be controlled with a resolution of 2N+M states rather than a resolution of 2N states as is common with standard methods.

    Abstract: A method and system for controlling the chromaticity and luminous flux output of a digitally controlled luminaire. The luminaire includes one or more light-emitting elements and one or more light sensors for providing optical feedback, which is filtered to remove undesired frequencies. The method and system employs a control system which can sample the filtered signals from the light sensors according to a predetermined feedback sampling frequency scheme, wherein this scheme is specifically configured to provide sufficient iterations of the feedback loop to be performed for adjustment of the chromaticity and luminous flux output of the light-emitting elements, without perceptible visual flicker or momentary chromaticity shifts.

    Abstract: The present invention provides a system and method for the diffusion of illumination from discrete light sources such that the illumination is blended and directed in one or more desired directions. The illumination system comprises a substrate having a plurality of light-emitting elements thereon which are arranged in an array, wherein these light-emitting elements produce illumination at one or more wavelengths. Proximate to the light-emitting elements is a diffuser, which collects the illumination produced by the discrete light-emitting elements and redirects this illumination in one or more predetermined directions, thereby blending together the one or more wavelengths of illumination and concentrating the illumination in the predetermined directions. The illumination system further comprises a power system, which provides energy to the light-emitting elements thereby resulting in their activation. Through the blending of the illumination produced by the discrete light-emitting elements together with the redirection of the illumination in a desired direction, both of which are enabled by the diffuser placed proximate to the discrete light-emitting elements, the creation of a blended pattern of illumination from these discrete light-emitting elements is provided, wherein this pattern of illumination can be one or more lines or planes of illumination.

    Abstract: The present invention provides a method and apparatus for controlling the thermal stress in lighting devices, for example light-emitting elements, that are exposed to large thermal gradients typically upon start-up, for example light-emitting elements operating in relatively cold ambient environments. The present invention provides an apparatus that can reduce this thermal stress, wherein the apparatus comprises a temperature determination mechanism for evaluating the temperature of the light-emitting elements prior to activation, and a control system to control the drive current such that it is gradually ramped up to the desired steady state peak current value, wherein the ramping of the drive current is dependent on the evaluated temperature of the light-emitting element.
