The light-emitting device includes a main body, a light-emitting module, and a press part located on the main body and configured to control on or off of the light-emitting module. The main body is provided with an accommodation space having the light-emitting module arranged therein. The main body includes a light guide, and light emitted by the light-emitting module is emitted outside of the main body through the light guide. The light guide includes a light exit surface and a light entrance surface. The light entrance surface is located on the circumferential inner sidewall of the accommodation space, and the light exit surface is located on the circumferential outer sidewall of the main body, and light emitted by the light-emitting module is emitted outside along a side of the main body.

A flexible inside corner trim piece is formed with concave depressions at hinge portions where wings attach to the body. The trim piece can be formed such that wings and a top cap lay flat in plane perpendicular to body or wings and top cap curve at an angle. Hinge portions can be narrow or wide and symmetrical or asymmetrical. The trim piece can be dyed, paintable, or present another decorative surface. The trim piece can include embedded lighting.

A laminar flow diffuser with integrated lighting has a frame for supporting an air plenum and a lower housing. The air plenum receives conditioned air from a source of conditioned. The lower housing is attached to the bottom of the plenum. An aperture plate damper installed below the top plenum regulates the flow of air from the plenum through the laminar flow diffuser. A clear or translucent engineered, fire rated polymer perforated diffuser face forms the outlet from the lower housing to the room below. LED strips are positioned around the inside periphery of the lower housing. A light guide is installed adjacent the LED lighting strips to spread the light across the area of the perforated diffuser face.

A lighting module for a refrigeration appliance has a housing provided with a light outlet. The housing includes a supporting edge surrounding the light outlet and an inner frame disposed along the supporting edge. The inner frame protrudes from the supporting edge in a direction away from the light outlet. The housing further has a light source. The light source includes a light emitting element and a substrate bearing the light emitting element. The light guide plate is supported on the supporting edge and includes a first end surface protruding toward the inner frame. The housing includes a mounting portion located in a space defined by the first end surface of the light guide plate, the supporting edge, and the inner frame. The substrate is mounted on the mounting portion, so that the light emitting element and the first end surface of the light guide plate face each other.

A lamp, a lamp system, a method for assembling a lamp system, and a method for disassembling a lamp system are provided. The lamp includes frame body, fixing mechanism, light guide plate, light source, electrical connecting assembly and suspension member. The fixing mechanism has a side surface, a top surface and a groove, and the groove extends from the side surface to the top surface. The groove has a first end and a second end respectively on the side surface and the top surface. The light guide plate, the light source and the fixing mechanism are disposed on the frame body. The electrical connecting assembly is disposed on the frame body. The electrical connecting assembly is connected to the light source to form an electrical loop. One end of the suspension member is passed through the groove from the first end and is positioned in the second end.

A knob for an appliance includes a handle. A light guide defines a recess. At least a portion of the handle is received within the recess of the light guide. A bezel is disposed over at least a portion of the light guide. The handle is rotatable relative to the bezel. A light emitter is disposed within the bezel. The light emitter is operable to emit light into the light guide. At least a portion of an interior surface of the light guide is textured, and an exterior surface of the light guide is smooth.

A refrigerator includes a cabinet having a storage chamber therein, and a door for opening and closing the cabinet, the door includes a door body and a panel assembly coupled to a front face of the door body, the panel assembly includes a front plate forming an outer appearance of a front face of the panel assembly, a light guide plate disposed to be spaced apart from a rear face of the front plate, a lighting device including a light source for irradiating light to the light guide plate and a substrate where the light source is disposed, wherein the lighting device is disposed to be spaced apart from one surface of the light guide plate, and a bracket having a receiving space for accommodating the lighting device therein, and the bracket includes a support for supporting the light guide plate or for determining the position of the light source.

A closure for an apparatus comprises: a plurality of light sources; a lightguide to distribute light from the plurality of light sources, the lightguide having a first primary surface opposite a second primary surface, wherein the first primary surface has a first surface treatment, and wherein light emitted from the lightguide indicates a status of the apparatus; and a frame supporting the plurality of light sources and the lightguide for selective movement of the closure vertically or horizontally relative to the apparatus.

A window can comprise a first side and a second side substantially parallel to the first side. The window can comprise an optical grating operatively positioned with respect to one of the first side and the second side. The optical grating can be used to determine a temperature at or near the respective one of the first side and the second side.

A refrigerator including a storage chamber. The refrigerator also includes a first sidewall and a second sidewall arranged to form at least a portion of both side surfaces of the storage chamber. The refrigerator further includes a light source arranged on the first sidewall to illuminate an inside of the storage chamber. The refrigerator also includes a light guide member provided inside the storage chamber and formed to extend between the first sidewall and the second sidewall to guide light emitted from the light source. The light guide member includes an incident surface arranged to face the first sidewall and an exit surface through which the light guided by the light guide member is emitted to an outside of the light guide member.
