Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] refer to Figure 1-6 As shown, an LED lamp with an adjustable light output angle includes a glass plate 1, an LED light source 2, a lamp tube 3, a light-shielding layer assembly, and an external control circuit; the divergent LED light source 2 is fixed in the middle of the lamp tube 3 , the size of the LED light source 2 is correspondingly matched with the elastic shading layer assembly, and the shading layer assembly is composed of a plurality of shading blocks 5 and a spring frame 4. The lamp tube 3 is composed of two parts, the tube wall and the tube bottom. The tube wall and the tube bottom are respectively placed with a horizontal direction energized coil 7 and a vertical energized coil 8, which can respectively generate magnetic fields in two directions perpendicular to each other. When the energized coils in two directions When the magnitude and direc...

Abstract

The invention belongs to the field of lamps, and provides an LED lamp with an adjustable bright emitting angle. The problem that a light emitting angle of the lamp is nonadjustable and cannot suitablefor multiple occasions is solved. A divergent LED light source is fixed to the middle position of a lamp barrel, the size of the LED light source corresponds to a shading layer assembling piece in amatched mode, and the shading layer assembling piece is composed of a plurality of shading blocks and a spring frame. The lamp barrel is composed of two parts of the barrel wall and the barrel bottom,the barrel wall and the barrel bottom are separately placed in a horizontal energized coil and a vertical energized coil, can separately generate magnetic fields vertical in two directions, when thecurrent magnitude and direction of the energized coils of the two directions change, the magnitude and direction of the two internal magnetic fields in the lamp barrel further change. In a finite space, a light emitting size of the lamp is changed by additionally arranging a mechanical movable structure which does not relay external action, gravity direction limit is removed, and the functionalityand applicability of the lamp are enhanced. A shading structure is accurately controlled through electrical control, and the accurate adjustment of the light emitting angle is realized.

Description

technical field [0001] The invention belongs to the field of lamps and is used to solve the problem that the light emitting angle of the lamp cannot be adjusted and cannot be applied to various occasions. Background technique [0002] LED is the fourth generation of green light source. It has outstanding light efficiency, low energy consumption, environmental protection and long life, and has been widely used in the field of lighting. With the improvement of people's living standards, there are different requirements for lighting in different occasions. At present, most of the lamps on the market have single functions and cannot meet the requirements of different light angles in different occasions. [0003] The patent with the publication number CN203810204U discloses an angle-adjustable LED lamp. The LED light source is arranged on the aluminum substrate. The upper and lower fixing plates are connected by springs, and the lower fixing plate is connected to a hook. The fixi...
