Abstract:
A belt-like flexible LED light can be bent in both an orthogonal direction to a light emitting direction and a vertical direction. Additionally, a circuit board and LED illuminating device are capable of implementing the LED light. An LED mounting circuit board, in which an LED mounting portion has a plurality of LEDs mounted in an array, is provided on a central part in a transverse direction of a long belt-like flexible board. Both sides of the LED mounting circuit board are in a transverse direction of the LED mounting portion and are provided with a first board and a second board having a feed pattern for causing a current to flow to the LEDs formed thereon. The LED mounting portion, the first board and second board are formed to be bendable and are used with the belt-like flexible LED light.
Abstract:
A semiconductor device includes a substrate formed of silicon carbide and a semiconductor layer of a first conductivity type provided on a first surface of the substrate. By irradiation with hydrogen ions, a high concentration hydrogen region having a hydrogen concentration of higher than 1015/cm3 is formed over a thickness of 1 μm or more. At least a part of the high concentration hydrogen region is formed in the semiconductor layer of the first conductivity type, and a lower end of the high concentration hydrogen region having a hydrogen concentration of 1015/cm3 or lower is positioned in the substrate or in the semiconductor layer.
Abstract:
A belt-like LED light includes an LED unit with a plurality of LEDs, a belt-like insulating case having a space and a partition plate, and a light-diffusing portion. The LED unit is inserted into the space of the belt-like insulating case, such that at least a part of the light transmits through the partition plate. The light-diffusing portion is continuously installed outside of the belt-like insulating case. The light-diffusing portion includes an open space and a curved section surrounding the open space. The curved section is made of light-diffusive material and diffusing the light having transmitted through the partition plate and the open space. The LEDs of the LED unit are connected with the electric wires for light-emitting. The LED unit is formed capable of being folded standing laterally against the light-emitting direction. The belt-like insulating case and the light-diffusing portion are made of flexible material.
