A luminaire, comprising a supporting frame (1), a power supply device (2), and one or more LED bars (3), wherein the power supply device (2) is fixed on the supporting frame (1);

• two sides of the supporting frame (1) are provided with a left bracket (4) and a right bracket (5);
• one or more left fixed frames (6) are fixed on the side edge of the left bracket (4);
• right fixed frames (7) symmetric to the left fixed frames (6) one by one are fixed on the side edge of the right bracket (5);
• one LED bar (3) is buckled between the symmetric left fixed frame (6) and right fixed frame (7) in each group;
• the right fixed frames (7) and the left fixed frames (6) each comprise one box type bracket (8);
• the front and rear ends of each box type bracket (8) are each provided with one buckle slot (10);
• the left and right ends of each LED bar (3) are each provided with one bar plug (11);
• the inner sides of the box type brackets (8) of the right fixed frames (7) are provided with female head copper pins (9) electrically connected to the power supply device (2);
• the bar plugs (11) on the right sides are provided with male head copper pins (12);
• one end of each male head copper pin (12) is matched with each female head copper pin (9), and the other end is electrically connected to each LED bar (3);
• the front and rear ends of each bar plug (11) are each provided with one elastic buckle (13);
• the elastic buckles (13) cooperate with the buckle slots (10);
• the right fixed frames (7) and the left fixed frames (6) are rotatably connected with the corresponding left bracket (4) or right bracket (5) through one angle adjustment mechanism;
• the angle adjustment mechanism comprises one rotating part (16), two elastic positioning devices (17) symmetrically fixed on two sides of the rotating part (16), and two angle adjustment limiting regions (47) cooperating with the two elastic positioning devices (17);
• and each angle adjustment limiting region (47) comprises one or more angle adjustment gears.
