[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate directions or positions, and the relationship is based on the directions or positional relationships shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figures 1 to 4 As shown, the multi-angle adjustable light source of this embodiment includes: an outer frame 1 and an LED board 2 arranged on the outer frame 1, the middle part of the outer frame 1 is concave to form a central installation area 11, and a plurality of edge installation areas 12 are evenly distributed around the central installation area 11, the LED board 2 is installed at the bottom of the central installation area 11 and the edge installation area 12, and a light homogenizing plate 3 is arranged outside the central installation area 11 and the edge installation area 12, and a cover plate 4 is arranged outside the light homogenizing plate 3, and the cover plate 4 is connected to the outer frame 1.

[0025] The number of edge mounting areas 12 is 4. As shown in the figure, there are 5 light-emitting areas, and the state of each light-emitting area can be controlled by a controller. The light-emitting area of ​​a single light-emitting area is 40mm*40mm.

[0026] The included angle between the light diffuser plate 3 on the edge mounting area 12 and the light diffuser plate 3 on the central mounting area 11 is 135°.

[0027] It also includes a controller for controlling the switch and brightness of the LED board 2 in the center installation area 11 and the edge installation area 12. The controller is connected to the light source through a connecting line to realize power supply and control. The controller uses a high-frequency, high-storage chip, with fast running speed and high stability; the controller can also be connected to a PC through a serial port, and the PC is used to switch the light source channel to control the brightness of the light source, which is convenient for integrating the light source into the product. The controller uses constant current control with high adjustment accuracy and good consistency.
