The invention provides an illumination system comprising a light-emitting device which excites a first luminescent element, which forms part of the light-emitting device. The light emitted from the first luminescent element and/or the light emitted by the light-emitting device excite a second luminescent element, physically separated from the light-emitting device. By employing two luminescent elements, the first element in the light-emitting device, and the second element physically separated from the light-emitting device, such as on a cover plate, the conversion of light produced by the light-emitting device is performed at both a “local” and a “remote” location, respectively, and the amount of luminescent material required at the remote location may be reduced compared to the situation of the prior art where the light conversion was only performed at a remote location.

In a light spot position detection device, in one frame of operation, under control of a control unit, pixel data obtained in a pixel section in exposure of a solid-state image sensor in synchronization with light emission of a light emitting element are added to corresponding storage portions in a memory unit, and pixel data obtained in exposure of the image sensor asynchronous to the light emission of the light emitting element are subtracted from the corresponding storage portions, to store pixel data of only signal light in the storage portions. A given number of frames of operation are repetitively performed to accumulate pixel data of only the signal light in the storage portions. The position of a light spot on the pixel section is calculated based on the pixel data of only the signal light and outputted whether the storage portions are saturated or not with the pixel data.

An LED backlight structure and technique for setting the voltages and currents for the LEDs are described. In one embodiment, red LEDs are connected in series between a first voltage regulator and a first controllable current source, green LEDs are connected in series between a second voltage regulator and a second controllable current source, and blue LEDs are connected in series between a third voltage regulator and a third controllable current source. The current sources may linear current regulators. After all the LEDs are mounted on a printed circuit board, each voltage regulator is controlled so that there is a minimum voltage drop across the current source to minimize energy dissipation by the current source. Also, after all the LEDs are mounted on the printed circuit board, the current sources are controlled to balance the three colors to achieve a target light output of the board using a light detection chamber. In another embodiment, a constant current source is connected to the series string of LEDs. PWM controllers control transistor switches connected in parallel across groups of LEDs, where the duty cycles set the average current through each group of LEDs. The control values used to achieve the target light characteristics are then stored in a memory on the board. With such a technique, LEDs do not need to be binned to match their efficiencies, since the controllable voltage and current sources compensate for the variety of LED efficiencies. Accordingly, all boards will have the same target light output using the particular values stored on each board. In other embodiments, not all the LEDs of a particular color are connected in series. The brightness levels of the LEDs may be further controlled by a PWM controller. The backlight may be for an LCD television or other color display.

Initially, “libraying” text is inserted on all scripts executed on the computer, allowing administrators to discern at a glance every script that has been executed. Furthermore, administrators can easily ascertain the results of all automatically run programs (such as overnight batch jobs) by looking in a common location rather than all over the computer. All scripts installed on a computer system are required to have the ability to generate uniform output. This output includes the script name, the time it was run, the user name and the script execution results. When a script is executed, it will write this detailed output into a predefined directory. There, a file is generated which lists all the parameters associated with the script execution. The parameters are then available for future review by administrators. Additionally, an executed script writes a summary output to a common file. This file provides a single point of reference and further provides a summary description for all activities.

The invention provides a direct-current microgrid control method and system based on hierarchical management. An overall control strategy of a direct-current microgrid is decomposed into an equipmentmanagement layer and a bus control layer structure. All parts of the microgrid are regulated based on own characteristics and working modes at the equipment management layer; and at a hybrid energy storage effect link, current controlling without energy storage battery compensation is carried out, so that the energy storage adjustment response speed and stability are improved. At the bus control layer, a set working mode controller carries out working mode division according to a fluctuation range of a bus voltage and the residual power of the battery, so that the system is able to carry out switching in different working states; and the working modes of all units of the equipment management layer are set based on different working modes, so that the stable operation capability of the direct-current microgrid is enhanced. And with consideration of the parallel energy storage control method, an adaptive droop coefficient regulator is established, so that the ring current influence between lines is suppressed and the time of reaching balancing of the parallel energy storage is shortened.
