Lighting fixture and ambient light

A lighting fixture, comprising:

• a base, a light-transmitting cover, a circuit board, and a plurality of connecting wires;
• wherein the base comprises a base portion and a boss portion extending upward from a top end of the base portion, the base is provided with an accommodation groove extending vertically through the boss portion and into the base portion, two connecting holes are provided at two opposite inner sidewalls of the accommodation groove, with the connecting holes extending horizontally and communicating with the base portion, the circuit board is arranged within the accommodation groove, and a top surface of the circuit board is provided with a light-emitting element electrically connected to the circuit board;
• the connecting wires sequentially pass through one of the connecting holes, the accommodation groove, and the other connecting hole, each of the connecting wires comprises a conductive wire and an outer skin wrapping the conductive wire, the conductive wire is electrically connected to the circuit board via a conductive member, and an outer sidewall of the outer skin is fixedly connected to an inner sidewall of the connecting hole by integral injection molding;
• the light-transmitting cover is mounted on an end of the base provided with the accommodation groove, the light-transmitting cover comprises a planar portion and a side portion, the side portion is formed on a surface of the planar portion facing the base and extended along a circumference of the planar portion, a connecting portion extending along the circumference of the planar portion is provided at an angle formed by a connection of the planar portion and the side portion, a surface of the connecting portion orthogonal to the side portion is provided with a connecting groove extending along the connecting portion, an inner sidewall of the connecting groove close to the side portion is provided with a connecting protrusion extending along the connecting portion, an end of the boss portion away from the base portion is ultrasonically welded to the connecting protrusion, during welding, a part of the connecting protrusion flows out in a fluid state and fills a gap between an outer sidewall of the boss portion and an inner sidewall of the side portion, and the end of the boss portion away from the base portion is inserted and fixed into the connecting groove.
