Abstract: A bulb-shaped LED lamp includes a plurality of high-intensity LED modules 2 where a high-intensity LED is attached on an LED fixing base plate, a heat sink 5 where the high-intensity LED modules 2 are attached on an end face in an axial direction thereof along a circumferential direction, for performing radiation of the high-intensity LED modules 2, a reflector 4 which is provided so as to surround the plurality of high-intensity LED modules 2, for guiding light from the high-intensity LED modules 2 forward, an electronic circuit for driving 6 which drives the high-intensity LED modules 2, a housing 7 which houses the heat sink 5, the electronic circuit for driving 6, and a portion of the reflector 4 therein, and a globe 8 which configures an outer shell together with the housing 7.

Abstract: An object is to provide an LED lamp in which the number of LEDs is reduced by using high-intensity LEDs, and point light sources are converted into a linear light source or the like by a light diffusion sheet. The LED lamp includes an outer shell case 2 with a U shape in section opening on one face, a reflecting plate 3 with a trapezoidal shape in section provided on the side of an opening portion in the outer shell case 2 and opening in the same direction as the outer shell case 2, a plurality of LED modules 5 using high-intensity LEDs 5a and mounted on a bottom portion which is a short side of the reflecting plate 3, a diffusion sheet 4 for diffusing light provided near the opening portion of the outer shell case 2, and a lighting circuit 6 for lighting the LEDs 5a provided on a bottom portion in the outer shell case 2.

Abstract: An electrodeless discharge lamp lighting fixture which can secure lightness even in the case of a dimmering control at a low temperature. The electrodeless discharge lamp lighting fixture according to the present invention comprises an electrodeless discharge lamp 1, a dimmering inverter 3 which is connected to an AC power supply 11 and applies a high-frequency voltage to the electrodeless discharge lamp 1, a controlling relay 5 adapted to receive an AC dimmering signal to turns ON/OFF, and a control substrate 4 which converts, into DC, the AC dimmering signal received from said controlling relay 5 and applies the DC dimmering signal to the dimmering inverter 3, wherein, in case the control relay 5 is ON, the control substrate 4 outputs a DC dimmering signal of 4 volts or greater, and the dimmering inverter 3 assumes an operation mode of about 50%.

Abstract: A plate positioning apparatus for use with a punch machine having a number one workpiece stopper that moves left and right along the direction of the X axis and a number two workpiece stopper that moves to and fro along the direction of the Y axis perpendicular to the X axis, each workpiece stopper having its own motor. The number one workpiece stopper moving left and right relative to the punch along the direction of the X axis structured with a corner cutout on its inner leading edge so as to allow the punch to pass through. The number two workpiece stopper moves to and fro relative to the punch along the direction of the Y axis structured with a cutout section in the middle of its leading edge so as to allow the punch to pass through, the two cutout openings meeting at the forwardmost point of intersection to allow the punch to pass through.
