Description

Technical Field

[0001] The utility model belongs to the technical field of high pole lamp lighting, in particular to a high pole lamp capable of adjusting the lighting angle. Background Art

[0002] High pole lamps are often used in lighting design, lighting and lighting operations. High pole lighting devices are usually installed to achieve large-scale centralized lighting. They are widely used in open areas such as city squares, airports, docks, and construction highways.

[0003] Due to the high height of the high pole lighting device, during the use of the high pole lamp, the bulb is generally installed and fixed on the lamp pole. Once the bulb is installed, the lighting angle of the lamp is fixed. Most of the high pole lamps sold on the market can only illuminate in a fixed single direction, and the illumination angle of the lamp body cannot be adjusted, and thus the lighting angle cannot be adjusted.

[0004] In view of the technical difficulties that the existing high pole lamps on the market cannot adjust the lighting angle and cannot provide directional angle illumination for the working environment, it is urgent to design a high pole lamp that can autonomously adjust the lighting angle. Utility Model Content

[0005] The purpose of the utility model is to provide a high pole lamp with adjustable lighting angle to solve the problems raised in the above background technology. The following technical solution is provided: a high pole lamp with adjustable lighting angle, comprising:

[0006] shell;

[0007] A swing assembly, one end of which is hingedly arranged on the housing;

[0008] The lamp body is fixedly arranged at one end of the swing assembly;

[0009] A reflector assembly is slidably disposed on the side wall of the housing and one end of the reflector assembly is hinged to the other end of the swing assembly;

[0010] The driving assembly is fixedly arranged on the outer side wall of the shell and is used for driving the swinging assembly to swing.

[0011] In the present technical solution, the shell of the device is installed on the high pole lamp stand by bolts or other means. When in use, the lamp body is first energized to make it perform lighting work. When the lighting angle needs to be adjusted according to the lighting environment, the driving component is started at this time. After the driving component is started, it drives the swing component to rotate. A crank slider mechanism is formed between the swing component and the reflector component, which causes the angle of the swing component to swing. Since the lamp body is installed on the bottom side of the swing component, the illumination angle of the lamp body changes. While the swing component drives the reflector component to swing, the position of the reflector component always remains parallel to the ground, and a reflector that can reflect the light source is provided inside the reflector component, thereby ensuring that the reflector component can keep reflecting the light source always toward the lower side of the reflector component.

[0012] In any of the above technical solutions, further, the swing assembly includes:

[0013] The rotating shaft is rotatably arranged on the side wall of the shell, a swing plate is fixedly arranged in the middle of the rotating shaft, a main reflector is arranged at the end surface of the swing plate, and the lamp body is fixedly arranged on the main reflector.

[0014] The reflector assembly includes a first guide groove, which is fixedly arranged on the inner side wall of the shell, and a second guide groove is also opened on the side wall of the shell, a guide rail is slidably arranged in the first guide groove, and the other end of the guide rail is slidably embedded in the second guide groove. A guide block is slidably arranged in the guide rail, and a secondary reflector is fixedly arranged at the middle of the guide block.

[0015] In the present technical solution, the extension directions of the first guide groove and the second guide groove are parallel, thereby ensuring that the guide rail can slide along the groove opening directions of the first guide groove and the second guide groove.

[0016] When the swing assembly swings counterclockwise downward, the auxiliary reflector is forced to move downward, and because the auxiliary reflector is connected to the guide block as a whole, the guide block is horizontally slidably arranged in the guide rail, so that the guide block slides horizontally in the guide rail and pushes the guide rail to slide only in the vertical direction in the first guide groove and the guide rail, thereby decomposing the combined movement of the auxiliary reflector in the horizontal and vertical directions, and the auxiliary reflector extends to the front end of the shell in a small range, thereby ensuring that the auxiliary reflector maintains a stable horizontal posture in space, so that the auxiliary reflector can continuously reflect the light source emitted from the lamp body to the lower side of the auxiliary reflector, thereby realizing the maximum utilization of the light source.

[0017] In any of the above technical solutions, further, the driving component includes:

[0018] A through slot is fixedly provided on the side wall of the housing, a cylindrical pin is slidably arranged in the through slot, one end of the cylindrical pin is fixedly connected to the swing plate, and the other end of the cylindrical pin extends out of the through slot and is fixedly connected to a rack. A motor is fixedly provided on the housing, and a driving gear is provided on the motor, and the driving gear meshes with the motor for transmission. The through slot and the rack are arc-shaped, and the arc centers of the two are colinear with the axis center of the rotating shaft.

[0019] In the present technical solution, the through groove and the rack are arc-shaped, and the arc section of the small end face has uniformly distributed teeth. The arc of the through groove and the arc of the rack are respectively a section of two concentric circles, and the centers of the two concentric circles are collinear with the axis of the rotating shaft. Therefore, it is possible to ensure that the swing plate and the rack always swing at the same angle, so that the driving gear can be rotated to always mesh with the rack for transmission, thereby realizing the control of the swing angle of the swing component.

[0020] The beneficial effects of the utility model are as follows: by providing a swing assembly and a reflector assembly, a crank slider mechanism is formed between the swing assembly and the reflector assembly, and by providing a first guide groove and a guide rail, the rotational freedom of the auxiliary reflector is restricted, thereby ensuring that the auxiliary reflector is always in a horizontal position when the swing assembly is swinging for angle adjustment. The auxiliary reflector is always in a horizontal position, which can ensure that the light source is irradiated to the bottom of the lamp body to the maximum extent, that is, the adjustment of the irradiation angle of the high pole lamp is realized, and the maximum utilization efficiency of the light source can be ensured.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] Embodiment 1:

[0029] like Figure 1-2 As shown, this embodiment provides a high pole lamp with adjustable lighting angle, comprising:

[0030] Housing 10;

[0031] A swing assembly 20, one end of which is hingedly disposed on the housing 10;

[0032] The lamp body 30 is fixedly disposed at one end of the swing assembly 20;

[0033] A reflector assembly 40 is slidably disposed on the side wall of the housing 10 and one end of the reflector assembly 40 is hinged to the other end of the swing assembly 20;

[0034] The driving assembly 50 is fixedly disposed on the outer wall of the housing 10 and is used to drive the swing assembly 20 to swing.

[0035] In the present technical solution, the housing 10 of the device is installed on the high pole lamp stand by bolts or other means. When in use, the lamp body 30 is first energized to make it perform lighting work. When the lighting angle needs to be adjusted according to the lighting environment, the driving component 50 is started at this time. After the driving component 50 is started, it drives the swing component 20 to rotate. A crank slider mechanism is formed between the swing component 20 and the reflector component 40, which causes the angle of the swing component 20 to swing. Since the lamp body 30 is installed on the bottom side of the swing component 20, the illumination angle of the lamp body 30 changes. While the swing component 20 drives the reflector component 40 to swing, the position of the reflector component 40 always remains parallel to the ground, and a reflector that can reflect the light source is provided inside the reflector component 40, thereby ensuring that the reflector component 40 can keep reflecting the light source always toward the lower side of the reflector component 40.

[0036] The lamp body 30 is the main light source for lighting work, and its angle adjustment can achieve the change of the main irradiation position of the light source. The reflector assembly 40 ensures the maximum utilization of the light source during the angle adjustment of the lamp body 30.

[0037] In a preferred embodiment of the present invention:

[0038] like Figure 2-3 As shown, specifically, the swing assembly 20 includes:

[0039] The rotating shaft 21 is rotatably disposed on the side wall of the housing 10 . A swing plate 22 is fixedly disposed in the middle of the rotating shaft 21 . A main reflector 23 is disposed at the end surface of the swing plate 22 . The lamp body 30 is fixedly disposed on the main reflector 23 .

[0040] The reflector assembly 40 includes a first guide groove 41, which is fixedly arranged on the inner side wall of the housing 10, and a second guide groove 42 is also provided on the side wall of the housing 10, a guide rail 43 is slidably arranged in the first guide groove 41, and the other end of the guide rail 43 is slidably embedded in the second guide groove 42. A guide block 44 is slidably arranged in the guide rail 43, and a secondary reflector 45 is fixedly arranged in the middle of the guide block 44.

[0041] In the present technical solution, the extension directions of the first guide groove 41 and the second guide groove 42 are parallel, so as to ensure that the guide rail 43 can slide along the groove direction of the first guide groove 41 and the second guide groove 42 .

[0042] When the swing assembly 20 swings downward counterclockwise, the auxiliary reflector 45 is forced to move downward. Because the auxiliary reflector 45 is connected to the guide block 44 as a whole, the guide block 44 is horizontally slidably set in the guide rail 43. At this time, the guide block 44 slides horizontally in the guide rail 43 and pushes the guide rail 43 to slide only in the vertical direction in the first guide groove 41 and the guide rail 43, thereby decomposing the combined movement of the auxiliary reflector 45 in the horizontal and vertical directions. The auxiliary reflector 45 extends to the front end of the shell 10 in a small range, thereby ensuring that the auxiliary reflector 45 maintains a stable horizontal posture in space, so that the auxiliary reflector 45 can continuously reflect the light source emitted from the lamp body 30 to the lower side of the auxiliary reflector 45, thereby realizing the maximum utilization of the light source.

[0043] In a preferred embodiment of the present invention:

[0044] like Figure 2-4 As shown, specifically, the drive assembly 50 includes:

[0045] The through slot 51 is fixedly provided on the side wall of the housing 10, and a cylindrical pin 52 is slidably provided in the through slot 51, one end of the cylindrical pin 52 is fixedly connected to the swing plate 22, and the other end of the cylindrical pin 52 extends from the through slot 51 and is fixedly connected to a rack 53. A motor 54 is fixedly provided on the housing 10, and a driving gear 55 is provided on the motor 54, and the driving gear 55 is meshed with the motor 54 for transmission. The through slot 51 and the rack 53 are arc-shaped, and the arc centers of the two are colinear with the axis center of the rotating shaft 21.

[0046] In the present technical solution, the through slot 51 and the rack 53 are arc-shaped, and the arc section of the small end surface has uniformly distributed teeth. The arc of the through slot 51 and the arc of the rack 53 are respectively a section of two concentric circles, and the centers of the two concentric circles are collinear with the axis of the rotating shaft 21. Therefore, it is possible to ensure that the swing plate 22 and the rack 53 always swing at the same angle, so that the driving gear 55 can be rotated to always mesh with the rack 53 for transmission, thereby realizing the control of the swing angle of the swing assembly 20.

[0047] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
