An electronic device includes a plurality of sub-electronic modules arranged side by side. Each of the sub-electronic modules includes a housing having a top wall, a bottom wall, and a pair of side walls, and a light guide pipe mounted on one of the side walls. The light guide pipe has an incident end, an emergent end located at a front portion of the housing, and a main body located between the incident end and the emergent end and extending in a length direction of the housing. The incident ends of the light guide pipes located between at least a pair of adjacent housings are staggered by a predetermined distance in the length direction.

A lighting device includes a light guide that propagates incoming light, and a lighting panel including a lighting region. A front side of the lighting panel excluding the lighting region is configured to prevent transmission of light, the light guide is covered by the lighting panel, the lighting device is configured such that the light emitted from the light guide passes through the lighting region of the lighting panel for illumination, and surfaces of the lighting panel surrounding the light guide are white in color.

An intelligent light-emitting device integrated with an illuminating object, the illuminator being an independent and removable component, comprising a LED light assembly, a control unit, a rechargeable battery, a switch and a wireless charging module, which are assembled and sealed to form a waterproof, portable and independent light-emitting device; the control unit configured to control different lighting mode of the LED light set and including a wireless remote control unit, remotely controlled by a light control. APP of an intelligent article; wherein the illuminating object includes a transparent or semi-transparent block with light-conducting function and a light-conducting groove; the block is a shoe sole, a lamp holder or a box; the light-emitting device is placed in the light-transmitting groove and removable therefrom.

A lighting device includes a light permeable body which has an aperture through which light enters the body. A light source is moveable relative to the body to enable the lighting device to adopt selectively one of a first configuration and a second configuration. In the first configuration, the light source is positioned over the aperture so that light emitted by the light source passes through the body before illuminating the room. In the second configuration, the light source is spaced laterally from the aperture so that the room is illuminated directly by light emitted from the light source.

A lighting engine, system and method of fabrication are described. The system contains a flexible printed circuit (FPC) shaped as a loop. LEDs are mounted on the FPC to emit light toward a center of the loop. A light guide positioned in an interior of the loop receives light emitted by the LEDs through an edge of the light guide. The light guide has slots formed therein that receive locator pins to limit thermal displacement of the light guide towards the LEDs. Other apparatuses, systems, and methods are also disclosed.

A lighting device may include a plurality of light sources which are disposed on the circumference of a concentric circle, a light guide which surrounds the light sources and is disposed adjacent to the light sources, and a cover member which surrounds the upper surfaces of the light sources and the upper and side surfaces of the light guide. The light guide has a first surface in the light source direction and a second surface in a direction opposite to the light source which have an inclination with respect to the optical axis of the light emitted from the light sources. The cover member has a light transmitting pattern in a light diffusion region facing the upper surface of the light guide.

Disclosed is a luminaire structure, comprising at least one light guide segment having opposed surface regions and defining a dimension therebetween. At least one edge region with at least one LED array configured to form an edge-lit optical coupling with the edge region. The light guide segment further includes a first sensor passage extending between the opposed surface regions to receive a sensor. At least one of the light guide segment, the first sensor passage and/or the sensor is configured so that light delivered to the light guide segment through the edge-lit optical coupling illuminates the light guide segment with reduced optical disruption by the presence of the sensor in the first sensor passage, when compared with a non edge-lit optical coupling configuration.

A lighting engine, system and method of fabrication are described. The engine contains a chassis having a side wall and bottom surface that define a cavity. A recess is formed in the bottom surface. A flexible printed circuit (FPC) is on the side wall and LEDs are mounted on the FPC to emit light toward a center of the cavity. A light guide positioned within the cavity receives light emitted by the LEDs through an edge of the light guide. A gasket disposed within the recess is in contact with a first surface of the light guide. A reflector within the cavity is adjacent to a second surface of the light guide opposite the first surface of the light guide. A backplate is attached to the chassis and configured to seal the cavity. Other apparatuses, systems, and methods are also disclosed.
