摘要： 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.

摘要： The present invention provides a luminance enhancement apparatus and method for use with light-emitting elements comprising a conversion system adjacent the light-emitting element for converting electromagnetic radiation of one or more wavelengths to alternate wavelengths. This conversion process can be enabled by the absorption of the one or more wavelengths by the conversion system and emission of the alternate wavelengths thereby. The conversion system comprises a predetermined surface relief pattern on the face opposite the light-emitting element to provide a means for reducing absorption of the emitted alternate wavelengths in addition to providing a means for reflection of the emitted alternate wavelengths from the conversion system with a reduced number of reflections, thereby enhancing the illumination provided by the light-emitting element. As the present invention operates on principles of increased surface area and self-excitation of the conversion materials through the use of a predetermined surface relief pattern, the present invention may be applied to both organic LEDs, phosphor-coated semiconductor LEDs, and light-emitting elements coated with a population of quantum dots embedded in a host matrix.

摘要： The present invention provides an illumination system enabling dynamic colour control of the illumination produced by the system. The illumination system comprises a plurality of light-emitting elements which create illumination at a number of different wavelengths wherein the colour that can be produced by the illumination system is based on the colour gamut defined by the colours of the individual light-emitting elements being blended. The system further includes at least one detecting device in order to collect information relating to the illumination being created by the plurality of light-emitting elements, wherein this information can relate to the luminous flux being produced at the various wavelengths. A computing system is integrated into the illumination system, wherein this computing system provides a means for receiving the information from the at least one detecting device and determines control parameters based on a multivariate function having a solution defining the hyperplane representing constant luminous intensity and chroma. Under these conditions the computing system can essentially linearise the information from the detecting device, thereby determining a number of control parameters from the input information, for transmission to a controller. The controller integrated into the system subsequently determines the control signals to be sent to the light-emitting elements in order to control the illumination produced thereby. In this manner, the illumination system according to the present invention can detect the produced illumination and dynamically alter the produced colour or intensity, for example, based on the collected information and the desired illumination result.

摘要： The present invention provides a method and apparatus for generating light having a desired chromaticity, wherein two or more light-emitting elements which emit light having a dominant wavelength different from the dominant wavelength of a desired chromaticity can be used to generate light having the desired chromaticity. In particular, the dominant wavelength of one light-emitting element is selected to be greater than that of the dominant wavelength of the desired chromaticity and the dominant wavelength of a second light-emitting element is selected to be less than the dominant wavelength of the desired chromaticity. Two or more light-emitting elements configured in this manner can be employed to generate one of each of the three or more display primaries required for a specific lighting application, for example backlighting of a display panel.

摘要： 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.

摘要： The present invention provides a parallel pulse code modulation system enabling the independent control of a plurality of groups of one or more electronic devices. The system comprises a memory unit for receiving control data, from an external source, wherein this memory unit is configured to enable writing of the control data thereto and reading of the control data therefrom. The system further comprises a multiplexer connected to the memory unit for receiving the control data from the memory unit and organizing the control data into a serial data stream comprising groups of data. A shift register connected to the multiplexer receives the serial data stream from the multiplexer and translates each group of data into a parallel data stream output. Each parallel data stream output represents control parameters for a particular group of one or more electronic devices. A latch connected to the shift register and to the plurality of groups of one or more electronic devices, receives each parallel data stream output and sends a particular parallel data stream output to a corresponding group of one or more electronic devices, thereby providing independent control of the plurality of groups of one or more electronic devices. A logic sequencer integrated into the system provides sequencing and timing signals to the memory unit, the multiplexer, the shift register and the latch, thereby controlling actions and timing thereof.

The luminaire comprises one or more light-emitting elements and one or more light sensors which can provide optical feedback, wherein this optical feedback is filtered to remove undesired frequencies. The method and system comprises 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.
