  • DC conversion system
    Patent number: 7511384
    Abstract: A DC conversion system includes a power-generating device, a power storage device, and a DC boost circuit. The power-generating device transforms power from natural resources such as solar power and wind force into a direct current power source. The direct current voltage output from the power-generating device can be stepped up directly from 6-12 volts to high voltage of 200-680 volts by the DC boost circuit and thereby obviate the need to perform a DC to AC conversion.

  • Lamp body for a fluorescent lamp
    Patent number: 7370986
    Abstract: A lamp body for a fluorescent lamp has multiple sections arranged on an inner surface of the lamp body. The sections include at least one coated section coated with fluorescent powders and at least one non-coated section being naked and kept free from fluorescent powders. The fluorescent powders generate visible lights when colliding with ultraviolet rays. The visible lights can directly pass out of the lamp body through the at least one non-coated section to form a light source and improve a luminance of the fluorescent lamp.
