[0002] Street lamps are used for lighting and have been used in most cities. The current street lamps have a fixed beam angle. Now when the lamp is installed on the lamp pole, the beam angle is fixed and cannot be adjusted. The beam angle is single and cannot be adjusted according to the specific situation. adjustments, limiting the scope of its functionality

Embodiment Construction
[0012] The present invention installs the lamp 2 on the lamp pole 1, and the joint surface of the two is a symmetrical plane 3 and a corresponding groove structure, such as figure 1 As shown, when the two are installed in the forward direction, the lamp 2 is installed horizontally; figure 2 As shown, when the two are installed in reverse, the lamp 2 is installed vertically, and its luminous angle changes.
[0013] The symmetry plane 3 of the present invention can be an ellipse or other symmetry plane, and the light-emitting cavity is set on the same side as the symmetry plane 3 .

The invention relates to a street lamp, which comprises a lamp post and a lamp, wherein the lamp is arranged on the lamp post, and the mating face of the lamp post and the lamp is a centrosymmetric symmetry plane. According to the street lamp, the lamp post is provided with the centrosymmetric symmetry plane, and the lamp is provided with a corresponding groove. Because of the characteristic that the symmetry plane is symmetric, when the symmetry plane is matched with the groove in the opposite direction, the position of the corresponding lamp on the lamp post is changed, thereby, the light-emitting angle of the lamp is changed. Therefore, compared with a traditional street lamp, the street lamp provided by the invention is adjustable in light-emitting angle, is wider in application range and is more flexible.
Description
technical field [0001] The invention relates to a street lamp, in particular to a street lamp with adjustable luminous angle. Background technique [0002] Street lamps are used for lighting and have been used in most cities. The current street lamps have a fixed beam angle. Now when the lamp is installed on the lamp pole, the beam angle is fixed and cannot be adjusted. The beam angle is single and cannot be adjusted according to the specific situation. adjustments, limiting its functional scope. Contents of the invention [0003] The purpose of the present invention is to provide a street lamp capable of adjusting the lighting angle according to the actual situation. [0004] To this end, the technical solution adopted by the present invention is: the present invention includes a lamp post and a lamp arranged on the lamp post, and the joint surface of the lamp post and the lamp is a symmetric plane about the center. [0005] The symmetrical surface of the light pole is ...
