Abstract: A dishwasher equipped with a lamp assembly. The lamp assembly includes a lamp bracket, a lamp cover and a plurality of fastening projections. The lamp bracket is fitted into an opening to accommodate the lamp from an outside of the inner casing. The lamp cover is detachably fitted into the lamp bracket from an inside of the inner casing. The plurality of fastening projections fit the lamp bracket into the opening. The fastening projections are projected from a front rim of the lamp bracket to be elastically deformable, and have gaps each corresponding to a thickness of the inner casing. The inner casing includes movement prevention notches extended outward from the opening at locations where the fastening projections will be interlocked.

Abstract: A head mounted display (HMD) that is worn on a user's head to display an image. The head mounted display includes a display body to display the image, a frame to support the display body, the frame being worn on the user's head, and an adjusting portion to rotatably connect the display body with the frame, wherein the user adjusts a focal point of the image in accordance with a vertical position of the user's eyes by rotating the display body relative to the frame.

Abstract: An illumination system for a display apparatus is capable of reducing electric power consumption and lengthening a life span by minimizing a loss of marginal rays that are spaced away from a main optical axis. The minimum loss of the marginal rays is obtained by a light reflective surface of a predetermined degree of curvature formed on an optical device for diffuse-reflecting and altering an optical path of a light from a light source.

Abstract: A snap door including a door housing, a door body, a latch switch and a spring, in which one side of a lower plane of the door housing is open for placing a PCB mounted with plural control switches therein. The door body includes a lower case, an upper cover, a knob assembly and a front cover. The knob assembly has a knob holder, plural remote control knobs and plural resilient bridge portions extending between the knob holder and remote control knobs. The knob holder is attached to a lower plane of the upper cover. Respective remote control knobs are formed by extension members extending to the rear side from the resilient bridge portions of the knob assembly, control buttons projectingly installed to the front side of upper planes of the extension members, and switch operative projections protrudingly installed to lower planes of the extension members. Respective remote control knobs are arranged to allow the switch operative projections to be placed on the upper portions of the control switches on the PCB.
