Abstract:
A system and method for accessing multimedia items using an electronic device determines a set of first level categories based on multimedia items associated with the electronic device. The system determines second level category graphics and first level category graphics corresponding to the set of first level categories. The first level category graphics are generated based on one or more second level category graphics associated with the first level category. The system displays a first view that comprises some or all of the first level category graphics. In response to a user input selecting a particular first level category graphic, the system shows a second view that simultaneously displays first level category graphics and second level category graphics associated with the selected first level category. In response to a user input selecting a second level category, the system displays accesses a multimedia item associated with the selected second level category.

Abstract:
A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.
