Abstract: Disclosed herein is a lighting apparatus using one or more fluorescent lamps. The lighting apparatus according to the present invention includes one or more sockets, a board, a ballast, and a Direct Current (DC) power supply. The sockets accommodate the fluorescent lamps. The board supports Light Emitting Diodes (LEDs) for emitting green light in a wavelength range of 498 to 530 nm, LEDs for emitting red light in a wavelength range of 620 to 700 nm, and LEDs for emitting bluish green at 495 nm. The ballast provides a ballast function to the fluorescent lamps. The DC power supply supplies DC power to the LEDs.

Abstract: Disclosed herein is an adapter device for enabling the use of a compact fluorescent lamp in a lighting apparatus having a socket for an incandescent lamp. The adapter device includes a fastening structure, a cap, green and red Light Emitting Diodes (LEDs), and a Direct Current (DC) power supply. The fastening structure fastens the compact fluorescent lamp. The cap supplies Alternating Current (AC) power to the fastening structure. The green LEDs emit light in a wavelength range of 498-530 nm, and the red LEDs emit light in a wavelength range of 620-700 nm. The LEDs are installed around the compact fluorescent lamp. The Direct Current (DC) power supply supplies DC power to the green LEDs and the red LEDs.

Abstract: A scheduling method implemented in an operating system kernel for supporting multimedia applications is provided. The micro-scheduling method includes the steps of determining a performance parameter by measuring I/O-bound job performance and CPU-bound job performance in a given application, and appropriately adjusting the performance parameter according to a policy set by a system administrator when carrying out job admission control. Determining an order of priority for processing application classes based on the performance measuring and job admission control by scheduling the periodical execution of I/O jobs of data which need not be moved to a user space due to the characteristics of multimedia applications, and executing a special I/O system call according to the order of priority for processing is also provided. The micro-scheduling method enables the support of accurate QoS for any operating system which supports multimedia applications.
