Description

Technical Field

[0001] The utility model relates to the technical field of garden landscape lamps, in particular to a high-low arm landscape lamp. Background Art

[0002] Landscape lights are an indispensable part of modern gardens. They are not only beautiful in themselves, but also can add light to the gardens at night, making it easier for tourists to enjoy the scenery at night. For example, landscape lights in the shape of red lanterns will give people a festive feeling, and green coconut tree lights erected by the pool will present a tropical atmosphere.

[0003] The existing landscape lights have poor lighting effects and require the use of high-power lighting lamps, which results in more serious power loss. In the prior art, there are landscape lights that use reflectors to adjust the adaptability of lighting lamps. For example, a high-low arm landscape light with publication number CN213453391U includes a lamp pole, a first lamp arm, a second lamp arm, a solar panel, a reflector and a lighting assembly, wherein the first lamp arm and the second lamp arm are respectively mounted on both sides of the lamp pole, and the height of the first lamp arm in the vertical direction is lower than that of the second lamp arm. An installation tube is provided at one end of the first lamp arm and the second lamp arm away from the lamp pole, and the installation tube passes through the solar panel and the reflector in sequence and is connected to the lighting assembly.

[0004] This type of landscape light reflects the light of the bulb through a reflector, thereby expanding the illumination range of the landscape light. However, this type of landscape light requires the installation of connecting arms of different heights, resulting in different heights of the lamp from the ground. In order to make the landscape light evenly illuminate the surroundings and avoid different illumination ranges at night, it is necessary to adjust the illumination range of the lamps at different heights. This type of landscape light can only adjust the power of the bulb through the circuit, and it is necessary to try different power bulbs according to the height of the lighting range, resulting in low adjustment efficiency. Summary of the invention

[0005] The purpose of the utility model is to solve the problem that the lighting range of the high and low arm landscape lamps in the above background technology is difficult to adjust, and to provide a high and low arm landscape lamp.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 As shown, the utility model is a high-low arm landscape lamp, comprising a fixing plate 1, a lamp post 2 is fixedly connected to the top of the fixing plate 1, the lamp post 2 is arranged along the vertical direction, and a top plate 3 is fixedly arranged on the top of the lamp post 2. A high connecting arm 4 and a low connecting arm 5 are arranged on the surface of the lamp post 2, the high connecting arm 4 is located above the low connecting arm 5, a solar panel 6 is arranged at the bottom of the high connecting arm 4 and the low connecting arm 5, and a reflector 7 is arranged below the solar panel 6. A threaded sleeve 8 is arranged below the reflector 7, the threaded sleeve 8 is arranged along the vertical direction, the top of the threaded sleeve 8 is fixedly connected to the bottom of the reflector 7, and the inner cavity of the threaded sleeve 8 is connected to the inner cavity of the corresponding high connecting arm 4 or the low connecting arm 5. A bulb 10 is fixedly arranged at the bottom of the threaded sleeve 8, and the wiring harness in the bulb 10 is routed through the inner cavity of the threaded sleeve 8 and the inner cavity of the corresponding connecting arm.

[0027] The surface of each light bulb 10 is provided with a lampshade structure 9, and the outer lampshade 91 of the lampshade structure 9 is provided on the outer surface of the light bulb 10, and the outer lampshade 91 has an outer shape of a truncated cone with a cross-sectional radius increasing from top to bottom. The threaded sleeve 8 is passed from the top surface to the bottom of the outer lampshade 91, and the threaded sleeve 8 is located at the position of the central axis of the outer lampshade 91. A connecting contact plate 94 is fixedly provided at the bottom of the threaded sleeve 8, and an elastic deformation plate 93 is provided at the bottom of the outer lampshade 91, and the deformation plate 93 is in contact with the connecting contact plate 94. A deformation cavity 92 is provided inside the outer lampshade 91, and the deformation cavity 92 is located above the forehead of the deformation plate 93. A reinforcing rib 11 is provided between the top surface of the fixed plate 1 and the surface of the lamp post 2.

[0028] When using this high-low arm landscape lamp, the lamp post 2 is fixed on the ground through the fixing plate 1 at the bottom, and the fixing plate 1 is fixed to the bottom surface by bolts; the top surface of the lamp post 2 is provided with a top plate 3, which plays a certain protective role on the top surface of the lamp post 2 while maintaining the beauty of the landscape lamp, and can prevent dust and rain from accumulating on the top surface of the top plate 3. The surface of the lamp post 2 is provided with a high connecting arm 4 and a low connecting arm 5 of different heights. The bulb 10 set at one end of the high connecting arm 4 and the low connecting arm 5 plays a role in lighting the road surface. The high connecting arm 4 and the low connecting arm 5 are set at different heights to make the unique shape of the surface of the lamp post 2 a landscape lamp. During the day, the solar panel 6 at the bottom of the connecting arm can absorb solar energy, thereby storing electrical energy for the bulb 10 below, and can supply power to the bulb 10 when the bulb 10 needs to work. The reflector 7 below the solar panel 6 can provide installation space for the bulb 10 below and the lampshade structure 9. Since the heights of the high connecting arm 4 and the low connecting arm 5 are different, the irradiation range of the bottom bulb 10 is affected, and the irradiation range of the bottom bulb 10 can be adjusted through the lampshade structure 9. By rotating the outer lampshade 91, the outer lampshade 91 rotates on the surface of the connecting sleeve, thereby driving the outer lampshade 91 to move vertically on the surface of the threaded sleeve 8. During the movement of the outer lampshade 91, the deformation plate 93 at the bottom will contact the top of the connecting resistance plate 94, and the connecting resistance plate 94 drives the deformation plate 93 to deform, and the deformation cavity 92 at the top provides deformation space for the deformation plate 93. The deformation plate 93 is subjected to the force of the connecting resistance plate 94, and the elastic deformation plate 93 bends downward, thereby reducing the cross section of the outer lampshade 91, and the outer lampshade 91 adjusts the light range of the internal bulb 10. In this way, the irradiation range of the connecting arm bulbs 10 with different heights can be adjusted.

[0029] Among them, there is a gap between the solar panel 6 and the reflector 7. After absorbing the heat from the sun, the solar panel 6 will increase its own temperature. The gap can prevent the reflector 7 and the solar panel 6 from directly contacting each other and being heated and deformed. At the same time, the gap can also provide a certain deformation space for the reflector 7 when it is deformed by heat; the material of the outer lampshade 91 has a certain light transmittance, so that the light of the bulb 10 can irradiate the top of the outer lampshade 91, and the light is reflected by the upper reflector 7 to increase the irradiation range; the setting of the deformation cavity 92 can also increase the light transmittance of the light upward.

[0030] Working principle of the utility model: a high-low arm landscape lamp of the utility model is provided with a threaded sleeve 8 and a lampshade structure 9. An outer lampshade 91 of the lampshade structure 9 rotates on the threaded sleeve 8, so as to adjust the distance between the outer lampshade 91 and the bulb 10. An elastic deformation plate 93 inside the outer lampshade 91 contacts the connecting contact plate, so as to deform the deformation plate 93, change the size of the bottom cross-section of the outer lampshade 91, and adjust the irradiation range of the bulb 10 inside the outer lampshade 91; a deformation cavity 92 is provided, and the deformation cavity 92 provides a deformation space for the deformation plate 93 at the bottom of the outer lampshade 91. At the same time, part of the light from the bulb 10 can pass through the top of the outer lampshade 91, and is reflected by the reflector to increase the illumination range. A part of the deformation cavity 92 increases the light transmittance of the top of the outer lampshade 91.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
