The frame body includes a bottom portion, a wall portion and at least one first positioning portion. The wall portion is connected with the bottom portion, and the first positioning portion is located at least one of the bottom portion and the wall portion. The light-emitting unit includes a circuit board and a plurality of light-emitting elements disposed on the circuit board. The circuit board includes at least one second positioning portion. The second positioning portion includes a notch and an extension portion extending from the circuit board. The first positioning portion and the second positioning portion engage with each other to connect the light-emitting unit with the frame body.

A device for mounting lighting sources on a substrate includes a channel-like mounting frame provided with fixing formations for fixing on said substrate, said mounting frame defining a cavity for receiving said lighting source with said lighting source resting on said substrate, a slider member which can be positioned in said cavity of said mounting frame to urge said lighting source toward said substrate; said slider member being slidable with respect to said mounting frame between an insertion position and a locking position, wherein said mounting frame and said slider member bear complementary engagement formations cooperating in a ramp-like manner to force said slider member and the lighting source urged thereby toward said substrate when said slider member is advanced from said insertion position toward said locking position.

The lighting apparatus has a wire box, a driver module, a light source and a light housing. The wire box is made of a heat dissipation material. The wire box is for placing a portion of an external wire. The driver module electrically connects to an electrode of the portion of the external wire. The light housing has a top cover and a surrounding wall. The top cover and the surrounding wall form a container space. The top cover has an inner side and an exterior side. The light source is thermally and structurally connected to the inner side for emitting a light via a light opening of the container space. The wire box is connected to the top cover of the light housing. Heat of the light source is transmitted to the wire box for heat dissipation via the back cover.

Example embodiments relate to luminaire systems with improved fastening means. One example luminaire system includes a first support provided with a recess. The luminaire system also includes a plurality of light sources arranged on said first support. In addition, the luminaire system includes a second support arranged opposite said first support. Further, the luminaire system includes one or more optical elements provided to said second support, and associated with the plurality of light sources. Additionally, the luminaire system includes a fastening element that includes a head portion and a rod portion. The second support is provided with a through-hole for receiving said head portion. Said rod portion extends through said through-hole and said recess in order to be fixed in the first support and/or in a portion of the luminaire system. The second support is provided with a protruding portion.

There is presented a lighting device comprising: several light-emitting filaments (15, 15′) with solid-state light sources and a circuit board (10) with first and second electrically conductive tracks (13, 14) following first and second paths, respectively. Each light-emitting filament (15, 15′) comprises a first electrical contact (19, 19′) electrically connected to the first track (13) at a first point on the first path, and a second electrical contact (20, 20′) electrically connected to the second track (14) at a second point on the second path. The first and second points associated with each light-emitting filament (15, 15′) are arranged on an axis (A) which is non-perpendicular to a tangent (T.sub.1) to the first path at the first point and to a tangent (T.sub.2) to the second path at the second point. The lighting device may be adapted to emit light from what appears to be a surface according to an observer.

A lighting unit includes a housing, a bus bar and a circuit substrate. In a state where the bus bar is installed in the housing, a base part and a first spring part of the bus bar are held by the housing in a first direction, and the bus bar is positioned with respect to the housing in the first direction. In a state where the circuit substrate is installed to the bus bar installed in the housing, a bus bar contact part of the circuit substrate contacts a substrate contact part provided to a second spring part of the bus bar such that the circuit substrate is held by the base part and the second spring part in the first direction, and the circuit substrate is positioned with respect to the bus bar in the first direction.
