An assembling mechanism for LED downlight includes a cylindrical body, at least one spring fixed on the cylindrical body, and a cover assembled on the at least one spring. Each of the at least one spring includes a fixing portion, a reed extending from the fixing portion along a rotation direction of the cylindrical body, and a catching portion disposed on the reed. The catching portion extends along the radial direction of the cylindrical body. The cover includes at least one clamping gap. Each of the at least one clamping gap includes an open provided along the rotation direction of the cylindrical body. The catching portion is inserted into the clamping gap from the opening by rotating the cover.

An omnidirectional lighting device may include a driver base and a plurality of elongated light sources. The driver base may include a driver configured to convert an external alternating-current (AC) power to a direct-current (DC) power and supply the DC power to the plurality of elongated light sources. Each of the plurality of elongated light sources protrudes independently out of a second side of the driver base, and each source is enclosed with a cylindrical lens. The plurality of the cylindrical lenses are aligned in parallel and of the same length. An aggregate lighting angle of the plurality of elongated light source may be 360 degrees.
