The cover includes a main cover body that is of a plate shape and covers the light-emitting element, and first engaging portions that are convex and formed on the main cover body. A light guide passes therethrough light emitted from the light-emitting element and is disposed on the main cover body. The support member includes a chamber that is defined therein and accommodates the board and the main cover body, second engaging portions that are formed therein and engage with the first engaging portions, and the first engaging portions are provided near the light guide.

Aspects of this invention relate to a system that provides an illuminated feature for an LED luminaire that can be used with opposite linear runs of LEDs to light the edges or sides of a luminaire without requiring additional LEDs. The system may include a light guide assembly located along an end housing of a light fixture, the light guide assembly including a light guide with a light guide end located proximate to one or more captured LEDs from a first plurality of LEDs located along a first side housing of the light fixture, and another light guide end located proximate to one or more captured LEDs from a second plurality of LEDs located along a second side housing of the light fixture, wherein the light guide receives the light from the one or more captured LEDs from the first plurality of LEDs and the one or more captured LEDs from the second plurality of LEDs and projects the light through the light guide, wherein when covered by a lens, the light emitted from the light guide is equivalent in appearance to the light emitted from the first plurality of LEDs and the second plurality of LEDs.

An electrical device includes a circuit board (101), a light source (104), and a light guide (105). The light guide receives light from the light source and conducts the received light to an end of the light guide so that the light crosses, in a direction parallel with the circuit board, an edge of the circuit board. The end of the light guide constitutes a display surface for showing the light to a user. On a fringe area extending from the edge of the circuit board a distance (D) towards the opposite edge of the circuit board, the light guide is between geometrical planes parallel and coinciding with surfaces of the circuit board. Hence, the light guide does not require room in directions perpendicular to the circuit board. Therefore, for example, more connectors, key buttons, and/or other instruments can be placed on a control panel of the electrical device.

A magnet valve coil unit includes a magnet coil and a circuit board connected thereto, encased by a molding material. An LED on the circuit board signals a switching status of the magnet coil. The LED is surrounded by the molding material at least in part. A light guide element is arranged in contact with the LED such that it directs light radiated from the LED to an external surface of the magnet valve coil unit. The magnet valve coil unit is manufactured by applying a deformable, transparent mass on the LED of a pre-assembled component containing the magnet coil and the circuit board on which the LED is arranged, and placing the pre-assembled component in a tool mold. The light guide element is arranged to be in contact with the transparent mass, and the pre-assembled component is encased with a molding material.

A loudspeaker mesh cover and a light-emitting loudspeaker having same are provided, the loudspeaker mesh cover is installed outside a loudspeaker, so as to play a certain protective role on the loudspeaker, enrich the light-emitting way and save the internal space of the loudspeaker. In addition, a light-emitting member is more convenient to disassemble in relative to a way of fixing a light-emitting assembly inside the loudspeaker. The loudspeaker mesh cover provided by the present disclosure may transform non-light-emitting loudspeakers on the market into light-emitting loudspeakers, so as to meet the demands of consumers for loudspeakers.

A luminaire includes a housing having at least one sidewall with an observable outer surface and a light feed edge. The housing sidewall is characterized in that light introduced through a light feed edge of the sidewall will propagate by internal reflections through the sidewall and will be extracted from the outer surface of the sidewall. A fractional amount of light emitted by the luminaire's light source is directed to the sidewall's light feed edge. When extracted, this fractional amount of source light produces an observable and aesthetically pleasing glow of light on the sidewall of the housing.

A light-emitting device includes a board holding an end of a connection terminal and on which an electronic component is mounted, a light-emitting element mounted on a surface of the board, a support member on which the board is placed, and a cover mounted in the support member. The cover includes a main cover body that is of a plate shape and covers the light-emitting element, and first engaging portions that are convex and formed on the main cover body. A light guide passes therethrough light emitted from the light-emitting element and is disposed on the main cover body. The support member includes a chamber that is defined therein and accommodates the board and the main cover body, second engaging portions that are formed therein and engage with the first engaging portions, and the first engaging portions are provided near the light guide.
