Abstract: A scroll compressor is disclosed. The scroll compressor may include a back pressure hole formed through a non-orbiting scroll and a back pressure chamber assembly such that a compression chamber and a back pressure chamber communicate with each other. A back pressure valve may be disposed inside of the back pressure hole and move along a longitudinal direction of the back pressure hole by a pressure difference between the compression chamber and the back pressure chamber, to vary a flow path area of the back pressure hole. The back pressure valve may include a valve body that extends in an axial direction and a plurality of holes formed through the valve body in the axial direction. With the configuration, pressure pulsation in the back pressure chamber may be suppressed or prevented.

Abstract: A scroll compressor is provided that may include a casing, a drive motor, an orbiting scroll, a non-orbiting scroll, and a floating plate provided with a cover portion to cover an area between an outer wall portion and an inner wall portion of the non-orbiting scroll so as to form a back pressure chamber with the non-orbiting scroll, and a valve accommodating portion that extends from the cover portion so as to accommodate a discharge valve configured to open and close a discharge port. Accordingly, structure for forming a back pressure chamber is simplified to thereby reduce the number of components and man-hours required for assembly.

Abstract: A scroll compressor is provided. In the scroll compressor, a valve accommodating groove that accommodates a discharge port and bypass holes is recessed by a predetermined depth into a rear surface of a non-orbiting scroll, and a valve guide is disposed between the rear surface of the non-orbiting scroll and a rear surface of the back pressure chamber assembly facing the rear surface of the non-orbiting scroll. Bypass valve guide holes into which bypass valves that open and close the bypass holes are slidably inserted are formed in the valve guide. Accordingly, the bypass valves that suppress or prevent overcompression in compression chambers are not fastened to a non-orbiting end plate, which may allow the non-orbiting end plate to be reduced in thickness. As the non-orbiting end plate is reduced in thickness, lengths of the bypass holes may be reduced, thereby decreasing dead volumes in the bypass holes.

Abstract: Provided are a light source module, a lighting device, and a system, which have uniform illuminance distribution, can obtain light having a large area, and are easy to assemble. The light module includes: a light source for emitting light; and a modulator disposed below the light source so as to modulate the emitted light into a line beam in the vertical direction. The light device includes a body, and a plurality of light source modules disposed on the lower side of the body so as to be arranged in an array in the horizontal direction, wherein the light source module includes: a support member provided in a first area of the lower side of the body; a light source provided in a second area of the lower side of the body so as to emit light in the downward direction; and the modulator provided on the lower side of the support member so as to modulate the emitted light into the line beam in the vertical direction.
