DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a structural schematic view of the first embodiment of the present application, and FIG. 2 is an exploded schematic view of the first embodiment of the present application. As shown in FIGS. 1 and 2, an LED lamp with an adjustable illuminating range includes a lamp body. The lamp body includes a base 1, a lamp housing 2 arranged on the base 1, and a light source assembly arranged inside the lamp housing 2. At least one side of the lamp housing 2 is an open structure allowing the light of the light source assembly to emit. An adjusting mechanism is configured inside the lamp housing 2 to adjust an illuminating range of the light emitted from the light source assembly. The emergence angle of the light source assembly or the size of the opening structure can be adjusted by the adjusting mechanism, thereby adjusting the illuminating range or the illuminating area of the emitted light and meeting different user demands.

Preferably, the adjusting mechanism includes at least one light distribution board 4 which is rotatably arranged inside the lamp housing 2. The emergence angle of the light source assembly can be adjusted by rotating the light distribution board 4, to achieve the goal of adjusting the illuminating range. Of course, a light-shielding structure such as a baffle can be provided at the opening structure, thereby achieving the effect of light distribution.

Preferably, two light distribution boards 4 are arranged symmetrically on two sides of the light source assembly. In this embodiment, the two light distribution plates 4 are independent rotatable structures, and either light distribution plate 4 can be adjusted independently, so as to meet different light distribution demands. Of course, the two light distribution plates 4 can also be adjusted synchronously by a linkage such as a gear or a synchronous belt, so as to ensure the symmetry of the illuminating area.

In this embodiment, each of two sides of the lamp housing 2 is an open structure. Two light source assemblies are configured to respectively correspond to two open structures. Two adjusting mechanisms are configured to respectively correspond to the two light source assemblies. That is to say, the light is emitted at both sides of the lamp housing 2, and the illuminating ranges of the emitted light at both sides of the lamp housing 2 are both adjustable, which is convenient for double-sided illumination. Especially when it is used as a wall panel lamp, the lamp has better decorative and illuminating effects on the wall body.

Preferably, in this embodiment, a light source mounting seat 7 is configured inside the lamp housing 2 to mount the light source assembly. The light distribution boards 4 are arranged on both sides of the light source mounting seat 7. The light source assembly includes an LED light source 91 arranged on the light source mounting seat 7, and a light transmitting plate 92 arranged on the light source mounting base 7 and corresponding to the LED light source 91. Of course, in a specific implementation, the light source assembly can be an integrated light source such as COB, which will not be described in detail herein.

Preferably, as shown in the drawings, a mounting plate 6 is arranged at a bottom of the lamp housing 2. The upper end of the light distribution board 4 is rotatably arranged at the top of the lamp housing 2 through a rotating structure, and the lower end of the light distribution board 4 is rotatably arranged on the mounting plate 6 through a rotating structure. The mounting plate 6 is configured to prevent the rotating structures, such as screws, shaft pins, pins, etc., from being exposed from the bottom (i.e., the outer side) of the lamp housing, so as to ensure the appearance effects. Of course, a rotating shaft can also be directly arranged at the bottom of the lamp housing 2, which will not be described in detail herein.

Preferably, the adjusting mechanism is provided with a first damping assembly capable of providing a rotation damping force for the light distribution board 4, so as to conveniently position the light distribution board 4, thereby enabling the lamp to maintain the adjusted illuminating range. As shown in the drawings, the first damping assembly is a rubber gasket 5 arranged at a rotating joint of the light distribution board 4. When assembled, the rubber gasket 5 is pressed and deformed to generate a larger friction force, thereby realizing the effect of positioning by damping. Of course, in a specific implementation, the first damping assembly can also be a friction plate or the like, which will not be described in detail herein.

Further, the lamp housing 2 is rotatably arranged on the base 1 through the rotating structures, such as screws, shaft pins, pins, etc., so as to adjust the opening direction of the lamp housing 2, thereby adjusting the illuminating direction and meeting different user demands.

Preferably, a second damping assembly, which is capable of providing a rotation damping force for the lamp housing 2, is arranged between the lamp housing 2 and the base 1, so as to position the lamp housing 2, thereby enabling the lamp to maintain the adjusted illuminating range. In this embodiment, the second damping assembly is a rubber ring 8 arranged at the junction of the lamp housing 2 and the base 1. When assembled, the rubber ring 8 is pressed and deformed to generate a larger friction force, thereby achieving the effect of positioning by damping. Of course, in a specific implementation, the second damping assembly can also be a friction plate or the like, which will not be described in detail herein.

In this embodiment, the lamp housing 2 is in a semicircular-cross-sectioned structure, and the light distribution board 4 is in a fan-shaped structure matching an inner wall of the semicircular-cross-sectioned lamp housing 2, thereby ensuring a larger adjustable angle and ensuring the compactness of fit. Of course, in a specific implementation, the lamp housing 2 can also be configured to be of other shapes, such as a trapezoidal shape, or in a square structure shown in FIG. 3 and FIG. 4. FIG. 3 is a structural schematic diagram illustrating a second embodiment of the present application. FIG. 4 is an exploded schematic diagram illustrating the second embodiment of the present application. As shown in FIGS. 3 and 4, in this embodiment, the lamp housing 2 is in a square structure, and the light distribution board 4 is in a square structure matching the inner wall of the square shaped lamp housing 2.

What described above are preferable embodiments of the present invention. Of course, the present invention can also adopt a different form from the above-described embodiments. For those skilled in the art, equivalent transformation or corresponding modifications made without departing from the spirits of the present invention are within the scope of the present invention.
