Description

Technical Field

[0001] This utility model relates to the field of garden lighting technology, and in particular to a garden light for nighttime use with projection function. Background Technology

[0002] Garden streetlights can improve the garden environment and enhance people's enjoyment of garden visits. During the day, garden streetlights can embellish the urban landscape, and at night they can provide necessary lighting. As modern gardens increasingly emphasize beautification, more and more trees are being planted to increase green areas. As a result, the sunlight on garden streetlights may be blocked by tree branches, affecting the brightness of the streetlights and making it inconvenient for people to visit the garden. Therefore, there is a need for garden lights with projection functions for nighttime use.

[0003] A search revealed that the Chinese patent "A Garden Light with Projection Function for Nighttime Use" (authorization announcement number CN220601367U) includes a connecting box. A main mounting plate is fixedly installed on one side of the connecting box, and a main lighting lamp body is fixedly installed on one side of the main mounting plate. A main protective plate is fixedly installed on the top of the main lighting lamp body, and a main connecting column is fixedly installed on the top of the main protective plate. By movably installing and adjusting the angle between the main lighting lamp and the main lighting lamp using the lighting mounting plate, and then using the main lighting lamp for illumination, multiple lighting modes can be used simultaneously using the main LED lighting lamp and the main lighting lamp, thereby increasing the diversity of garden lighting functions and improving the brightness and illumination range. However, the above method has the following defects in actual use: the height of the illumination point and the illumination range are fixed, which easily leads to the phenomenon that the illumination source is blocked, the illumination range is too large or too small, and it is not easy to adjust it according to the vegetation growth and lighting needs. Utility Model Content

[0004] Therefore, it is necessary to provide a nighttime garden light with projection function to address the problem that it is not easy to adjust the illumination point and illumination range according to the vegetation growth and lighting needs.

[0005] A garden light for nighttime use with projection function includes a light pole and a lamp holder installed at its end. A set of lighting lamps is arranged on the outer side of the lamp holder, and a projection lamp is arranged on the outer side of the light pole. It also includes an adjustment mechanism, which is arranged on the outer side of the projection lamp and is used to adjust the projection range of the projection lamp. The adjustment mechanism includes a set of support rods and a set of light-shielding pads. The light-shielding pads are installed between two adjacent support rods, and the support rods and light-shielding pads are arranged in a ring around the axis of the projection lamp.

[0006] In one embodiment, a collar is slidably sleeved on the outer side of the lamp post, the projection lamp is disposed inside the collar, and a first electric push rod for driving the collar to move vertically is disposed inside the lamp post.

[0007] In one embodiment, the collar has a rotatable support frame inside, one end of the support rod is mounted to the support frame via a hinge shaft, the projection lamp is mounted inside the support frame, and the collar has a motor for driving the support frame to rotate inside.

[0008] In one embodiment, a traction rope is provided on the outer side of the support rod, and an adjusting ring is slidably sleeved on the outer side of the support frame, with one end of the traction rope installed on the outer side of the adjusting ring.

[0009] In one embodiment, a second electric push rod for driving the adjusting ring is mounted on the outer side of the support frame, and a torsion spring is sleeved on the outer side of the hinge shaft.

[0010] In one embodiment, the light-shielding pad is made of EPDM rubber and carbon black filled into the interior of the EPDM rubber.

[0011] In one embodiment, a crossbar is provided between the first electric push rod and the collar, the crossbar passing through and slidably connected to the outside of the lamp post, and a set of corrugated tubes inside the lamp post are provided on the outside of the crossbar.

[0012] In one embodiment, the collar has a wire hole inside, which extends into the interior of one of the bellows. Beneficial effects

[0013] 1. By setting up support rods and light-shielding pads, the synchronous movement of a set of support rods can drive the corresponding light-shielding pads to follow the movement, thereby changing the blocking range of the light-shielding pads on the projector lamps, thus completing the adjustment of the light source projection range and reducing the phenomenon of excessive or insufficient illumination range to meet different usage needs.

[0014] 2. By setting the first electric push rod, the collar can be driven to move the projector light, thereby adjusting the height of the illumination point.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following is combined with Figures 1-5 This invention describes a garden light with projection function for nighttime use.

[0025] In one embodiment, a night garden light with projection function includes a lamp post 100 and a lamp holder installed at its end. A set of lighting lamps is provided on the outer side of the lamp holder, and a projection lamp 200 is provided on the outer side of the lamp post 100. It also includes an adjustment mechanism 300, which is located on the outer side of the projection lamp 200 and is used to adjust the projection range of the projection lamp 200. The adjustment mechanism 300 includes a set of support rods 310 and a set of light-shielding pads 320. The light-shielding pads 320 are installed between two adjacent support rods 310. The set of support rods 310 and the light-shielding pads 320 are both distributed in a ring around the axis of the projection lamp 200.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a collar 110 is slidably sleeved on the outer side of the lamp post 100, and a projection lamp 200 is disposed inside the collar 110. A first electric push rod 120 for driving the collar 110 to move vertically is disposed inside the lamp post 100.

[0027] In this embodiment, a lamp on a lamp holder is used to complete the regular lighting operation. When it is necessary to project light into a specific area, the projector 200 is activated. During the projection process, the user can drive a set of support rods 310 to move synchronously according to the usage requirements, thereby driving the light-shielding pad 320 to change the blocking range of the projector 200, thereby changing the illumination range formed. In addition, if there is vegetation blocking during the projection of road light source, the first electric push rod 120 can be activated to drive the height of the projector 200 to change, so that the light source projection path avoids the corresponding vegetation and ensures the light source projection effect.

[0028] It should be noted that when adjusting the projection range, if the projection is for a road, the range can be adjusted according to the road width; if the projection is for a specific landscape or vegetation, the range can be adjusted according to the size of the landscape area and the vegetation. The specific adjustment method should be selected according to the actual usage needs.

[0029] like Figure 2 and Figure 3 As shown, a rotatable support frame 130 is provided inside the collar 110. One end of the support rod 310 is mounted to the support frame 130 via a hinge shaft. The projection lamp 200 is mounted inside the support frame 130. A motor 131 for driving the support frame 130 to rotate is provided inside the collar 110.

[0030] The motor 131 drives the support frame 130 to move, which allows the projector lamp 200 to follow the movement, thereby changing the projection angle of the light source, helping to avoid vegetation that blocks the light source, and meeting different projection needs.

[0031] like Figure 4 and Figure 5 As shown, a traction rope 311 is provided on the outer side of the support rod 310, and an adjusting ring 132 is slidably sleeved on the outer side of the support frame 130. One end of the traction rope 311 is installed to the outer side of the adjusting ring 132.

[0032] When it is necessary to expand the projection range, the adjustment ring 132 can be driven to move away from the projection direction, and the traction rope 311 will be pulled, thereby causing a set of support rods 310 to drive a set of light-shielding pads 320 to move outward, thereby increasing the illumination range of the projection lamp 200.

[0033] like Figure 5 As shown, a second electric push rod 133 for driving the adjusting ring 132 is installed on the outer side of the support frame 130, and a torsion spring is sleeved on the outer side of the hinge shaft.

[0034] The second electric push rod 133 is used to drive the adjustment ring 132. When it is necessary to reduce the projection range, the adjustment ring 132 can be driven to move closer to the projection direction. At this time, the deformation force of the torsion spring will drive the corresponding support rod 310 to reset, so that the light shielding pad 320 increases the blocking range of the projection lamp 200, that is, the projection range is reduced.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, the light-shielding pad 320 is made of EPDM rubber and carbon black filled into the interior of the EPDM rubber.

[0036] This allows the light-shielding pad 320 to have good light-shielding properties, and the deformation capability of the rubber itself can ensure the blocking effect on the projector lamp 200 after adjustment.

[0037] like Figure 3 As shown, a crossbar is provided between the first electric push rod 120 and the collar 110. The crossbar passes through and is slidably connected to the outside of the lamp post 100. A set of corrugated pipes inside the lamp post 100 is provided on the outside of the crossbar.

[0038] A crossbar is used to drive the collar 110, and a bellows is used to protect and shield the movement path of the crossbar, reducing the occurrence of accidental entry of external dust and rainwater.

[0039] like Figure 3 As shown, the collar 110 has a wire hole inside, which extends into the interior of one of the bellows.

[0040] The use of a wire hole facilitates the insertion of the cable of the projection lamp 200 into the lamp post 100 along the wire hole and the corrugated pipe.

[0041] Working principle: When projection is required, the first electric push rod 120 is activated, driving the collar 110 to adjust the projection lamp 200 to the corresponding height. Then, the motor 131 is activated, and the support frame 130 is used to adjust the illumination angle of the projection lamp 200. Then, according to the projection requirements, the second electric push rod 133 is activated, causing the adjusting ring 132 to pull the corresponding traction rope 311, which in turn pulls the corresponding support rod 310 to move, changing the blocking range of the light-shielding pad 320 on the projection lamp 200, thus changing the projection range of the light source. After all adjustments are completed, the projection lamp 200 can be started to operate and the light source projection operation can be carried out.

[0042] It should be noted that the first electric actuator 120, motor 131, projector lamp 200 and lighting lamp, and second electric actuator 133 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the first electric actuator 120, motor 131, projector lamp 200 and lighting lamp, and second electric actuator 133 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0043] The control of the aforementioned electrical components is achieved by establishing a signal connection with the back-end control equipment for garden management, allowing managers to perform remote control.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
