摘要:
A laundry treating apparatus including a plurality of LEDs (60) mounted on a PCB (21A), a light guide (90) including inner (92) and outer (94) walls and ribs (100) disposed between the inner and outer walls to define cells (U) accommodating the plurality of LEDs, and a window (82) through which light emitted from the plurality of LEDs passes, wherein at least one rib includes a first portion (110) that is decreased in thickness toward the window and is pointed toward the window. A continuously connected integral lighting pattern is created on the window, and a neat and elegant lighting pattern is created by a simple structure.

Described is an illumination structure for a key of a keyboard. The illumination structure is used to uniformly illuminate the key and any glyphs that are present on the key. The illumination structure includes a light guide having various features that increase total internal reflection and also illuminate the glyphs of the key.

Disclosed is a control knob having an image output part. The control knob having an image output part of the present invention comprises: a head part through which an image is output; a body part into which a portion of the head part is inserted; a guide part which is provided inside the body part and coupled to the head part so as to guide the horizontal movement of the head part; and a returning part which is connected to the head part with the guide part and guides the head part horizontally moved along the guide part to the central portion of the body part.
摘要:
A key that includes a body with an optically transmissive or light permeable region and an optical film coupled to or carried by the light permeable region. The key also includes a resilient structure coupled to the body. The key can be assembled or coupled to, or disposed relative or adjacent to, a display screen. The key also includes a switch actuator (e.g., an electromechanical switch actuator or contact element). Displacement of the key, more specifically the body of the key, displaces the switch actuator for actuating a switch. The resilient structure is configured to bias the body at a first position. The body can be actuated or displaced from the first position to a second position for effectuating corresponding displacement of the switch actuator and actuation of the switch. The resilient structure provides or establishes a positive tactile feedback upon user-directed or user-controlled actuation or displacement of the body. The resilient structure and/or the switch actuator is positioned and configured to minimize, reduce, or eliminate obstruction of light transmission through the light permeable region of the body.

The invention relates to a switching device (1) for a MV electric power distribution network (100). The switching device comprises electric contacts (2, 3), which are electrically connectable to a conductor (P) of said electric power distribution network, and a control unit (5). The switching device comprises signalling means (6) emitting visible light externally to said switching device, said signalling means being controlled by said control unit.
