    摘要： A chair according to an embodiment of the present invention includes a seat frame, a plurality of legs, a backrest and an armrest. The plurality of legs are rotatably coupled to the seat frame at front and rear portions of the seat frame. The backrest is rotatably coupled to the seat frame at the rear portion of the seat frame. The armrest is rotatably coupled to upper ends of the legs. The armrest includes a movable member and a first elastic member. The movable member is retained inside the armrest and is movable along the armrest. The movable member is rotatably coupled to the backrest. The first elastic member is located inside the armrest and applies an elastic restoration force against the movement of the movable member.

    摘要： A light-emitting module includes a light guide plate and a light source unit in accordance with an embodiment. The light guide plate include an upper surface, a lower surface facing the upper surface, a plurality of side surfaces connecting the upper surface and the lower surface, and a cross-sectional surface connected to at least one of the side surfaces. The light source unit includes a substrate disposed in correspondence with the cross-sectional surface and a point light source mounted on the substrate to emit light to the cross-sectional surface. Thus, light-emitting efficiency may be enhanced and the arrangement of point light sources may be optimized, so that a required amount of emitted light may be obtained using a small number of the point light sources. In addition, uniformity of luminance and heat-radiating efficiency may also be enhanced.
