[0004] To solve the prior art problems, the utility model discloses a adjustable angle surface -mounted spotlight, which comprises a cylindrical lamp cylinder and a lamp stand, a notch extending to the top is arranged on the upper end of the side wall of the lamp cylinder, a fixed shaft is arranged in the notch, a connecting part is arranged at the lower end of the lamp stand, the connecting part is hinged with the fixed shaft through the notch, the connecting part is arranged on one side of the lower end of the lamp stand, a recess is arranged in the middle of the lower end of the lamp stand, and the interference part between the lamp cylinder and the lower end surface of the lamp stand can pass through the recess when the lamp cylinder rotates around the axis of the fixed shaft.

[0005] The utility model has the advantages that: the recess is arranged in the middle of the lower end of the lamp stand, the interference part between the lamp cylinder and the lower end surface of the lamp stand can pass through the recess when the lamp cylinder rotates around the axis of the fixed shaft, so that a larger anti-interference gap is not necessary between the lower end surface of the lamp stand and the upper end surface of the lamp cylinder, the length of the lamp body can be shortened, and the overall performance and appearance of the lamp are improved; and since the connecting part is arranged on one side of the lower end surface of the lamp stand, the rotating radius of the interference part of the lamp cylinder can be reduced, and the anti-interference gap between the lamp cylinder and the lamp stand is further reduced.

[0006] As a further improvement of this utility model, a baffle plate flush with the outer side of the lamp tube and covering the notch is provided on the outside of the connecting part; thus, the connecting part is not exposed in the lamp tube notch, resulting in better product integrity and aesthetics. The baffle plate extends below the notch, and at least one of the overlapping parts of the lower end of the baffle plate and the lower end of the notch is provided with a clearance slope; the gap between the baffle plate and the lower end of the notch is small. Both the overlapping parts of the lower end of the baffle plate and the lower end of the notch are provided with clearance slopes; thus, the gap between the baffle plate and the lower end of the notch is even smaller. A limiting part higher than the enclosure is provided in the recess, and the top of the lamp tube corresponds to the groove of the limiting part. The limiting part can abut against the bottom of the groove to limit the rotation angle of the lamp tube; this can hide the gap between the limiting part and the upper surface of the lamp tube, resulting in better product aesthetics. The lamp holder is a cylinder with an opening at one end. A base plate is installed on the opening. The connecting part is located on one side of the base plate, and the limiting part is located in the middle of the base plate. The installation depth of the base plate is lower than the lower end face of the lamp holder, and the limiting part is higher than the lower end face of the lamp holder. The space between the base plate and the lower end face of the lamp holder forms the recess. This makes the manufacturing method of the product simpler. Attached Figure Description

[0013] To further understand the features, technical means, specific purposes, and functions of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. The descriptions of component positions (including but not limited to: upper, lower, inner, outer, left, right, etc.) are for reference only when referring to the positions of the components shown in the accompanying drawings. Their purpose is to facilitate understanding of the relative relationships between the components and does not represent an absolute limitation on the scope of protection of this utility model. Those skilled in the art will understand that the description of relative positions may change when the view direction changes, but the essential relative positional relationships between the components remain unchanged.

[0014] Reference Figure 1 . An adjustable angle surface mounted spotlight, comprising a cylindrical lamp barrel 1 and a lamp holder 2, the lamp barrel 1 and the lamp holder 2 are connected by a hinge. The lamp barrel 1 is internally installed with light source components such as light source, lens and reflector cup. The lamp holder 1 is used for mounting on a fixed object, and the lamp holder 1 can be placed with a driving power supply for LED light source.

[0015] Reference Figures 1 to 3 . The lamp barrel 1 is a barrel body made by die casting process, the side wall upper end of which is provided with a notch 11 extending to the top end, the notch 11 is provided with a fixed shaft 12, and the side wall bottom of the notch 11 is provided with a first let-in inclined surface 111. The top end of the lamp barrel 1 is provided with a groove 13 and a heat sink.

[0016] Reference Figures 1 to 5 . The lamp holder 2 is a cylinder with one end opening 20 manufactured by stamping or die casting. The opening 20 is installed with a bottom plate 21, one side of which is provided with a connecting part 22, and the middle part of the bottom plate 12 is provided with a limiting part 23 matched with the groove 13 at the top end of the lamp barrel 1. The bottom plate 21 is installed in the opening of the lamp holder 1 by screws, and the installation depth of the bottom plate 21 is lower than the lower end surface 24 of the lamp holder, and the limiting part 23 is higher than the lower end surface 24 of the lamp holder. In this way, a recess 25 with the bottom plate 21 as the bottom is formed in the middle part of the lower end surface 24 of the lamp holder 2. The connecting part 22 is provided with a mounting hole 26 with its axis perpendicular to the axis of the lamp holder 2. The lamp holder 2 is movably sleeved on the fixed shaft 12 of the lamp barrel 1 through the mounting hole 26, so that the two are hinged. The outer side of the connecting part 22 is provided with a baffle 27 flush with the outer side of the lamp barrel 1, which can cover the notch 11 on the side wall of the lamp barrel 1. In this embodiment, the curvature of the baffle 27 is the same as the side wall of the lamp barrel 1, which can form a complete barrel profile with the side wall of the lamp barrel 1. Of course, as required by the installation process, a very small movement gap is reserved between the two sides of the baffle 27 and the side wall of the lamp barrel 1. As a more optimal solution, the length of the baffle 27 after installation is longer than the length of the notch 11 on the side wall of the lamp barrel 1, and the lower end of the baffle 27 overlaps with the lower end of the notch 11, and is provided with a second let-in inclined surface 271 matched with the first let-in inclined surface 111. Since the baffle 27 is flush with the outer side of the lamp barrel 1, and the length of the baffle 27 is longer than the length of the notch 11 on the side wall of the lamp barrel 1, a let-in inclined surface is arranged at one of the overlapping parts, which can avoid interference between the two, so that the baffle 27 can block the gap at the lower end of the notch 11.

[0017] Reference Figure 4 And Figure 5, the hidden lines in the figure are represented by dotted lines, and components and lines unrelated to the utility model are not shown. When the axis of the lamp cylinder 1 coincides with the axis of the lamp holder 1 and the light emission angle is zero degrees, the limiting portion 23 on the lamp holder 1 abuts against the bottom surface of the groove 13 on the upper end of the lamp cylinder 1, and the baffle 27 outside the connecting portion 13 can shield the gap 11 on the side wall of the lamp cylinder 1 and the gap below the gap 11. Referring to Figure 5 When the lamp cylinder 1 rotates around the axis of the fixed shaft 21, the top end of the lamp cylinder 1 is located at the left side of the fixed shaft 21, which is an interference position 28 with the lower end surface of the lamp holder 2. The interference position 28 enters the middle part of the lamp holder 2 from the edge of the lamp holder 2. Since the middle part of the lamp holder 2 is provided with a recess 13, the interference position 28 can pass through the recess 13, so that a large anti-interference gap does not need to be reserved between the lower end surface 24 of the lamp holder 2 and the upper end surface of the lamp cylinder 1, the length of the lamp body can be shortened, and the product appearance can be improved. In addition, since the connecting portion 22 is arranged on one side of the bottom of the lamp holder 2, the rotating radius of the interference position 28 can be shortened, and the depth of the recess 25 can be reduced. When the lamp cylinder 1 rotates to the position where the axis thereof is perpendicular to the axis of the lamp holder 1 and the light emission angle is ninety degrees, the bottom of the gap 11 of the lamp cylinder 1 abuts against the outside of the side wall of the lamp holder 1 to limit the position.
