A refrigerator includes a cabinet forming a storage space, a main door that opens and closes the storage space while defining an opening part that is in communication with the storage space, a sub-door mounted to the main door and configured to open and close the opening part, the sub-door including a panel assembly for allowing selective viewing of an inside of the opening part, the injection port is provided at a lower side of the sub-door to direct an insulating foaming solution to a space in the sub-door, a detection device for detecting an operation of a user, a lighting unit inside the refrigerator that turns on based on user operation to allow selective viewing of the inner side of the opening part, and a display unit inside the refrigerator at a position corresponding to the panel.

An illumination apparatus includes a main light source, a half minor, and a diffusion plate. The main light source emits main light. The half mirror is spaced apart from the main light source. The half mirror reflects a first light travelling in a first direction among the main light source. The half mirror has a reflective surface reflecting the first light to travel in a second direction. The diffusion plate is disposed between the main light source and the half mirror not overlapping the reflective surface. The diffusion plate has a first horizontal surface and a second horizontal surface. The second horizontal surface is a rear surface of the first horizontal surface. The diffusion plate transmits a second light incident on the first horizontal surface among the main light. The diffusion plate scatters the second light from the second horizontal surface.

A light-emitting device includes a substrate, a light-emitting element provided on the substrate, the light-emitting element being configured to emit a first light, a wavelength conversion layer provided on the light-emitting element and containing a plurality of wavelength conversion particles configured to convert a wavelength of a part of the first light and to emit a second light, a light-transmissive plate provided above the wavelength conversion layer, and a wall including a light-reflective material, the wall surrounding the wavelength conversion layer and the light-transmissive plate and being in contact with a lateral surface of the light-transmissive plate at an inner surface of the wall. An upper portion of the wavelength conversion layer includes protrusions and recesses defined by the plurality of wavelength conversion particles. The wavelength conversion layer and the light-transmissive plate define an air layer therebetween.

The conspicuity of a light emitting surface provided along an outer edge of an input member is enhanced. An input device (10) includes an upper cabinet section (41) having an opening formed therein, an input member (20) that has an upper surface to be touched by a user with a finger and that is disposed inside the opening, and a light diffusing member (71) having a light emitting surface (E2) located along an outer edge of the input member (20). The light emitting surface (E2) has a first region (71g) exposed in a gap between an inner edge of the opening of the upper cabinet section (41) and an outer edge of the input member (20) and a second region (71h) positioned on an inner side of the outer edge of the input member (20) and below a peripheral portion (21a) of the input member (20).

An electronic device includes a back frame, a first heat source, a second heat source, a guiding member and a fan. The first heat source is disposed on a first side of the back frame. The second heat source is disposed on a second side of the back frame. The guiding member is disposed on the second side of the back frame. The fan is disposed corresponding to the guiding member. At least part of an airflow path is formed between the first heat source and the second heat source.

A solid state lamp includes a connector and a bulb portion with multiple strips.

An LED lighting device or LED lamp comprises one or more LED packages, and a switch comprising at least two selectable positions. At least one selectable position corresponds to a set operating mode and one selectable position corresponds to a configurable operating mode. When the switch is in the selectable position corresponding to the set operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, the one or more LED packages continue to be operated in accordance with the predefined operating light qualities corresponding to the set operating mode. When the switch is in the selectable position corresponding to the configurable operating mode, responsive to receiving an indication of user input for selecting user-selected operating light qualities, operation of the one or more LED packages is modified in accordance with the user-selected operating light qualities.
