In this embodiment, the specific structure of the rotating arm 2 is as shown in fig. 3, a lamp socket 23 is disposed on the rotating arm 2, and at least one pair of reflective plates 22 for supporting the second light source is disposed on the lamp socket 23. The second light source is a COB light source 21, and a light emitting surface of the COB light source 21 faces the outer side of the rotating arm 2, namely, the side far away from the supporting arm. The surface of the second light source far away from the lamp holder 23 is also provided with a transparent lampshade 24 for protecting the second light source. The COB light source 21 is a high-light-efficiency integrated surface light source technology for directly attaching an LED chip to a mirror surface metal substrate with high light reflection rate, the technology eliminates the concept of a bracket, and has no electroless plating, reflow soldering and pasting procedures, the procedures are reduced by about one third, the cost is saved by one third, and the light emitting area and the overall dimension of the light source can be designed according to the product overall structure. On one hand, the common folding lamp is mainly used for a table lamp, after the common folding lamp is opened, the inner side of the rotating arm 2 faces downwards, and therefore the light emitting surface is arranged on the inner side of the rotating arm 2. However, in the present embodiment, in order to facilitate the illumination device to illuminate various angles, the light emitting surface of the second light source is disposed outside the rotating arm 2. If the lamp is not rotated, the lamp can illuminate the upper part or the lower part, and the lamp can illuminate the rear part after rotating a certain angle. In order to save space and make the lighting device more portable, it is preferable that the rotating arm 2 is a hollow structure, and the second light source is disposed inside the rotating arm 2.

The one end of swinging boom 2 is passed through rotation axis 3 and is connected support arm 1 one end, and when the swinging boom 2 need not to rotate, the other end of swinging boom 2 passes through buckle 4 to be fixed on the lateral wall of support arm 1. The arrangement is to make the lighting device smaller and more convenient to carry. The reflector 22 in the rotating arm 2, which is far from the end of the rotating shaft 3, is connected to one end of a spring 42, the other end of the spring 42 is connected to a spring plate 41, a hole is formed in the spring plate 41, the buckle 4 is inserted into the hole, and the other end of the buckle 4 abuts against the side wall of the support arm 1. Because the elastic sheet 41 is connected with the spring 42, and the spring 42 is connected with the reflector 22, when the rotary shaft 3 drives the rotary arm 2 to rotate, the spring 42 stretches to drive the elastic sheet 41 to move, so that the buckle 4 rotates, and the rotary arm 2 is separated. After the use is finished, as long as the rotating arm 2 is rotated back, the rotating arm 2 can be fixed by reversely rotating the buckle 4.

In order to fix the rotating arm 2 rotating to a preset angle, as shown in fig. 4, one end of the rotating arm 2 is inserted into the middle of the rotating shaft 3, a damping gasket 33 is sleeved at the joint of the rotating shaft 3 and the rotating arm 2, and the damping gasket 33 is sleeved on two connecting surfaces of the rotating shaft and the rotating arm 2. The end of the rotary shaft 3 is inserted into a sleeve 31 having an annular projection 32, the end face of the rotary shaft 3 abuts against the annular projection 32, and the side of the annular projection 32 remote from the end face of the rotary shaft 3 is provided with a retaining member 34, which is preferably a self-tapping screw, but any structure that can press the damping washer 33 and the annular projection 32 can be used as the retaining member 34 in the present embodiment, not limited to the self-tapping screw. When the rotating arm 2 rotates, the locking member 34 is in an unlocked free state, and at this time, the rotating shaft 3 and the annular boss 32 are independent from each other, and the rotating arm 2 can rotate freely. When the rotating arm 2 is rotated to a predetermined position, the locking member 34 is locked to bring the sleeve 31 into close contact with the damping washer 33, thereby restricting the rotation of the rotating shaft 3 and fixing the rotating arm 2 at the predetermined position.
