2results about How to "Improve brightness effect" patented technology

The utility model provides a kind of key light guide cover and light guide key assembly, key light guide cover includes base body, pressure-bearing body and support body, support body is fixedly connected between base body and pressure-bearing body, and the relative height between the front of pressure-bearing body and the front of base body is greater than zero, the front of pressure-bearing body includes light transmission area and backlight area, and the thickness of backlight area is greater than the thickness of light transmission area.Light guide key assembly includes aforementioned key light guide cover and light source.The utility model discloses technical scheme, because the thickness of backlight area is greater than the thickness of light transmission area, the light propagation path of light source generated light is shorter in light transmission area, and the intensity and brightness loss of light are lower, so as to enhance light transmission area brightness effect, and the light propagation path of light source generated light is longer in backlight area, so that the intensity and brightness of reflected light are weakened, the interference effect of reflected light and light propagation in light transmission area is reduced, light is reduced, so that user observes correct character or pattern from light transmission area, and misoperation to key is avoided.

The application discloses a kind of refrigerator aluminum alloy door ornament piece gouging processing fixing device, including operation table, outer blocking part is established on operation table, inner supporting part, outer blocking part includes the blocking along with the shape of the outer edge of workpiece cooperation, the upper edge of blocking along is lower than the edge of workpiece upper edge, so that the processing part of workpiece is exposed;Inner supporting part includes fixed block, prop open block, wedge-shaped component is established between fixed block and prop open block, beaker is established between wedge-shaped component and prop open block mutually and is pasted and slides inclined plane;Inner supporting part further includes elastic reset unit, elastic reset unit drives prop open block and moves in the direction of fixed block under free state, prop open block and outer blocking part form the profiling clamping gap between them, which is matched with the shape of workpiece.The refrigerator aluminum alloy door ornament piece gouging processing fixing device of the application is simultaneously clamped to the inner wall of workpiece by each prop open block of inner supporting part, and the extrusion direction of prop open block is perpendicular to the inner wall surface of attack, so as to avoid scratching the inner surface of workpiece during the process of fixing workpiece.
