  • Patent number: 10134908
    Abstract: A MISFET is formed to include: a co-doped layer that is formed over a substrate and has an n-type semiconductor region and a p-type semiconductor region; and a gate electrode formed over the co-doped layer via a gate insulation film. The co-doped layer contains a larger amount of Mg, a p-type impurity, than that of Si, an n-type impurity. Accordingly, the carriers (electrons) resulting from the n-type impurities (herein, Si) in the co-doped layer are canceled by the carriers (holes) resulting from p-type impurities (herein, Mg), thereby allowing the co-doped layer to serve as the p-type semiconductor region. Mg can be inactivated by introducing hydrogen into, of the co-doped layer, a region where the n-type semiconductor region is to be formed, thereby allowing the region to serve as the n-type semiconductor region. By thus introducing hydrogen into the co-doped layer, the p-type semiconductor region and the n-type semiconductor region can be formed in the same layer.

The operating circuit also has a control unit (16) that detects a residual ripple in the voltage (UPFC) in the supply chain before (18a), in (18b) or after (18c) the PFC circuit (11) and causes the frequency of the PWM modulation of the current through the illuminant (17) to be selected as a function of the frequency of the residual ripple.

  • Patent number: 9148921
    Abstract: A system including first and second lamps, one of an inductor or a transformer, first and second switches, and a control module. The first lamp generates a first output of light having a first color. The second lamp generates a second output of light having a second color. The first and second outputs of light are mixed to provide a mixture of light having a third color. The transformer includes first and second coils. The first and second coils supply power respectively to the first and second lamps. The first and second switches are connected respectively to the first and second coils. The control module alters the third color by controlling (i) a state of the first switch to adjust a first amount of current supplied to the first lamp, and (ii) a state of the second switch to adjust a second amount of current supplied to the second lamp.

  • Patent number: 9112123
    Abstract: [Problem] To provide a light-emitting device which does not undergo the deterioration in luminous efficiency associated with the long-term use. [Solution] A light-emitting device (1) comprises a light-emitting element (10) which can emit blue light and a phosphor (2) which is composed of a single kind of single crystal and can emit yellow light upon the irradiation with the light emitted from the light-emitting element (10) which serves as excitation light. Thus, it becomes possible to prevent the deterioration in luminous efficiency associated with the deterioration in a binder or the like compared with a light-emitting device which utilizes multiple kinds of granular phosphors, because any binder for binding phosphors to each other is not required in the light-emitting device (1).

  • Patent number: 9035327
    Abstract: A multi-chip light emitting device (LED) uses a low-cost carrier structure that facilitates the use of substrates that are optimized to support the devices that require a substrate. Depending upon the type of LED elements used, some of the LED elements may be mounted on the carrier structure, rather than on the more expensive ceramic substrate. In like manner, other devices, such as sensors and control elements, may be mounted on the carrier structure as well. Because the carrier and substrate structures are formed independent of the encapsulation and other after-formation processes, these structures can be tested prior to encapsulation, thereby avoiding the cost of these processes being applied to inoperative structures.
