Description

Technical Field

[0001] The present application relates to the technical field of lighting fixtures, and in particular to a landscape lamp capable of reducing light pollution. Background Art

[0002] Light pollution refers to light pollution caused by excessive, inappropriate or unnecessary human activities, which damages the environment and affects the health of residents. When the light exceeds a certain level, it may affect both day and night animals, plants and humans. As the process of urbanization accelerates, people begin to realize the impact of landscape and courtyard light pollution. Light pollution from outdoor lighting at night refers to the interference light (called trespass light in the United States and "obstruction light" in Japan) formed by the scattered light, sky light, drying light and reflected light generated by outdoor lighting at night, such as landscape lighting of buildings or structures, road and traffic lighting, square or construction site lighting, advertising sign lighting and garden landscape lighting. These lights will have a negative impact or harm on human health, transportation, astronomical observation, plant and animal growth and the ecological environment.

[0003] Landscape lights are often installed next to green grass or small trees in cities. When lit at night, the night view of the city becomes pleasing to the eye. However, existing landscape lights often use low-position floodlights to illuminate green grass or small trees, which will generate a large amount of scattered interference light, which is easy to interfere with pedestrians. If the power of the lamp is large, the scattered interference light may even affect the work and rest of nearby animals. Therefore, it is urgent to propose a landscape lamp that can reduce light pollution. Utility Model Content

[0004] The present application provides a landscape lamp that can reduce light pollution, which can effectively solve the problems existing in the landscape lamps in the above-mentioned prior art.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0011] The number of the through holes is equal to the number of the light-transmitting holes, and the area of ​​the through holes is not less than the area of ​​the light-transmitting holes; a limit baffle is provided on the top of the rotating baffle, the inner diameter of the limit baffle is smaller than the inner diameter of the port on the rotating baffle, and the outer contour of the limit baffle is fixedly connected to the lampshade.

[0012] Furthermore, an opening is provided in the middle of the top of the lampshade; the upper end of the lamp holder extends upward and is connected to the opening at the top of the lampshade;

[0013] A reflector is provided directly above the lampshade, and a reflective coating is coated on the lower side of the reflector; the reflector and the lamp holder are connected via a plurality of vertical support columns, and the plurality of support columns are evenly distributed along the circumference of the outer side of the lighting lamp, and there are gaps between adjacent support columns.

[0014] Furthermore, the projection of the lampshade on the horizontal plane falls within the projection of the reflector on the horizontal plane.

[0015] Furthermore, an annular translucent plastic plate is installed in the lower end of the lampshade, and a plurality of penetrating decorative holes are evenly arranged on the plastic plate along the circumference.

[0019] The lighting lamp of the present application can be supported above the grass or landscape trees by a lamp pole, and the light generated by the lighting lamp can be evenly illuminated on the lampshade through the light-transmitting holes on the lamp holder. Since the inner side of the lampshade is coated with an oil-reflective coating and the shape of the lampshade is an inverted bowl, the light irradiated on the inner side of the lampshade will, under the limitation of the lampshade, shine on the grass or landscape trees in a specific area below, thereby achieving the effect of landscape lighting.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0028] like Figure 1-Figure 3 As shown, a landscape lamp capable of reducing light pollution disclosed in the present application comprises a lamp pole 1, a trumpet-shaped lamp holder 2 is installed on the top of the lamp pole 1, and a lighting lamp 3 is installed in the lamp holder 2; a lamp shade 4 is coaxially sleeved on the outer side of the lamp holder 2, and the inner side of the lamp shade 4 is coated with a reflective coating, and the shape of the lamp shade 4 is similar to an inverted bowl; the middle position of the top of the lamp shade 4 is located directly above the upper port of the lamp holder 2, the upper port of the lamp holder 2 is connected to the lamp shade 4, and a plurality of light-transmitting holes 5 are evenly opened around the lamp holder 2; an adjustment component 6 is provided on the inner side of the lamp holder 2, and the adjustment component 6 can be used to adjust the aperture of the plurality of light-transmitting holes 5.

[0029] In the above embodiments, the lamp pole 1 of the present application can support the lamp holder 2 at the top, so that the lighting lamp 3 is located above the grass or small landscape trees to be illuminated, and the interior of the lamp pole 1 is a hollow structure that can be used to lay the cables required for the lighting lamp 3. The reflective coating coated inside the lampshade 4 of the present application is similar to the coating inside the reflector in the prior art, and can be an aluminum film, a nano-reflective film, a lattice reflective film, an electroplated coating, etc. Its main function is to reflect the light irradiated thereon. The reflective coating on the lampshade 4 of the present application can be made into a rough surface with a certain degree of roughness, so that a diffuse reflection effect can be formed when reflecting light, thereby converting the light emitted by the lighting lamp 3 into soft reflected light.

[0030] Since the shape of the lampshade 4 above the lighting lamp 3 is similar to an inverted bowl, and a plurality of light-transmitting holes 5 are provided on the lamp holder 2 outside the lighting lamp 3, when the lighting lamp 3 emits light at night, the light will shine on the reflective coating inside the lampshade 4 through the plurality of light-transmitting holes 5. Since the side line of the lampshade 4 is similar to a parabola, the light irradiating the inside of the lampshade 4 will be reflected downward by the reflective coating thereon, thereby reducing the direct light of the lighting lamp 3 from being converted into reflected light. The lampshade 4 can also limit the softened reflected light, so that the reflected light will only illuminate the grass or small landscape trees in a specific area below the lampshade 4. Since the lighting lamp 3 with higher brightness of the present application is hidden in the lampshade 4, it will not interfere with the sight of pedestrians at night. In addition, the landscape lights of the present application use a method of irradiating grass and small landscape trees downward; compared with the underground landscape lights in the prior art, the present application can greatly reduce the spill light directed into the air and the surroundings, and the light reflected by the protective cover of the present application is softer than the direct illumination method adopted by the landscape lights in the prior art, which can effectively reduce the impact of the use of landscape lights on the surrounding animals.

[0031] Different species of grass and small landscape trees may have different sensitivities to light, and the adjustment component 6 provided in the lamp holder 2 of the present application can be used to adjust the apertures of the plurality of light-transmitting holes 5. Thus, in actual use, the installer can adjust the adjustment component 6 in the lamp holder 2 according to the grass species or tree species on site, so that the light intensity generated by the landscape lamp of the present application can adapt to the grass species and tree species on site.

[0032] Furthermore, if Figure 2 and Figure 3 As shown, the adjustment assembly 6 includes a rotating baffle 61, which is placed in the lamp holder 2, and the outer wall of the rotating baffle 61 is in contact with the inner wall of the lamp holder 2, and a plurality of through holes 62 are evenly arranged on the rotating baffle 61 along the circumferential direction;

[0033] The number of through holes 62 is equal to the number of light-transmitting holes 5, and the area of ​​the through holes 62 is not less than the area of ​​the light-transmitting holes 5; a limit baffle 63 is provided on the top of the rotating partition 61, and the inner diameter of the limit baffle 63 is smaller than the inner diameter of the upper port of the rotating partition 61, and the outer contour of the limit baffle 63 is fixedly connected to the lampshade 4.

[0034] In the above embodiments, the lower end of the rotating partition 61 of the present application is placed at the bottom of the inner side of the lamp holder 2, so that the lamp holder 2 can provide support for the rotating partition 61. A limit baffle 63 is provided above the rotating partition 61 of the present application, and the inner diameter of the limit baffle 63 is smaller than the inner diameter of the upper port of the rotating partition 61. In this way, the limit baffle 63 fixedly installed on the lamp cover 4 can limit the rotating partition 61 in the vertical direction. In this way, the rotating partition 61 can be prevented from detaching from the lamp holder 2 during use, which not only has the effect of preventing loss, but also facilitates workers to quickly and smoothly rotate the rotating partition 61 in the lamp holder 2.

[0035] The through holes 62 uniformly arranged along the circumferential direction on the rotating baffle 61 of the present application are not only equal in number to the number of the light-transmitting holes 5 on the lamp holder 2, but the shape and size of a single through hole 62 can be preferably the same as the shape and size of a single light-transmitting hole 5. In this way, when in use, when the multiple through holes 62 on the rotating baffle 61 are aligned one by one with the multiple light-transmitting holes 5 on the lamp holder 2, the brightness of the reflected light generated downward by the lampshade 4 can be at the maximum state. When the multiple through holes 62 on the rotating baffle 61 and the multiple light-transmitting holes 5 on the lamp holder 2 only partially overlap, the brightness of the light of the landscape lamp of the present application directed toward the grass and landscape trees will be weakened. The worker can control the size of the overlapping area of ​​the through holes 62 and the light-transmitting holes 5 by controlling the rotation angle of the rotating baffle 61, thereby realizing the adjustment of the lighting brightness of the grass and landscape trees by the landscape lamp, effectively improving the convenience and scope of application of the present application.

[0036] Furthermore, if Figure 1-Figure 3 As shown, an opening is provided in the middle of the top of the lampshade 4; the upper end of the lamp holder 2 extends upward and is connected to the opening at the top of the lampshade 4;

[0037] A reflector 7 is provided directly above the lampshade 4, and a reflective coating is coated on the lower side of the reflector 7; the reflector 7 and the lamp holder 2 are connected by a plurality of vertical support columns 8, and the plurality of support columns 8 are evenly distributed along the circumference of the outer side of the lighting lamp 3, and there are gaps between adjacent support columns 8.

[0038] In the above embodiments, the opening provided in the middle position of the top of the lampshade 4 of the present application allows part of the light of the illuminating lamp 3 to irradiate upward toward the reflector 7. The outer shape of the reflector 7 of the present application is similar to an inverted dish. Compared with the protective cover, the slope of the side line of the reflector 7 of the present application is significantly gentler. In this way, the light emitted upward by the illuminating lamp 3 can be reflected to a larger area around the landscape lamp after hitting the reflective coating of the reflector 7. In this way, part of the light can be used by the reflector 7 above the lampshade 4 to illuminate the nearby roads, thereby providing a guiding lighting effect for pedestrians at night.

[0039] Furthermore, if Figure 1As shown, the projection of the lampshade 4 on the horizontal plane falls within the projection of the reflector 7 on the horizontal plane.

[0040] In the above embodiments, since the reflector 7 of the present application is located at the highest point of the entire landscape lamp, the reflector 7 of the present application is arranged in the above manner. In actual use, the reflector 7 can protect the lampshade 4 below, preventing rainwater and the like from drifting into the lamp holder 2 from the opening at the top of the lampshade 4, thereby affecting the service life of the lighting lamp 3 in the lamp holder 2.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, an annular translucent plastic plate 9 is installed in the lower end of the lampshade 4, and a plurality of penetrating decorative holes 10 are evenly arranged on the plastic plate 9 along the circumferential direction.

[0042] In the above embodiments, when the light reflected by the lampshade 4 irradiates downward, the intensity of the light passing through the translucent plastic plate 9 will be significantly weaker than the intensity of the light passing through the decorative hole 10 passing through the plastic plate 9. In this way, the light passing through the decorative hole 10 can cast a light spot of a specific shape on the grass or landscape trees. For example, the shape of the decorative hole 10 is set to be a butterfly shape. In this way, the light reflected by the lampshade 4 passes through the plastic plate 9 and irradiates the grass or landscape trees to be illuminated, forming a plurality of butterfly-shaped light spots, thereby making the illuminated grass and landscape trees more smart and beautiful.

[0043] Furthermore, if Figure 4 and Figure 5 As shown, the plastic plate 9 is composed of two sub-plates 91 of equal shape, each sub-plate 91 has a plurality of mounting holes 92 on its edge, and a plurality of fixing plates 93 with through holes are provided on the inner side of the lower port of the lampshade 4; the mounting holes 92 on the sub-plate 91 and the fixing plates 93 on the lampshade 4 can be connected together by bolts and nuts.

[0044] In the above embodiment, when the shape of the light spot projected on the grass or small landscape trees needs to be changed into another shape, the worker only needs to remove the bolts and nuts between the two sub-plates 91 and the fixing plate 93 on the lampshade 4 for fixing them, and then put the two sub-plates 91 with the new decorative holes 10 back into the lampshade 4, and buckle them into a ring around the lamp pole 1, and then use the bolts and nuts to fix the new sub-plates 91. In this way, in actual use, the user can project the desired shape of the light spot on the grass or small landscape trees as needed, making the application more flexible to use.

[0045] Furthermore, if Figure 1 As shown, a lace is provided at the lower end of the lampshade 4.

[0046] In the above embodiments, the lace provided at the lower end of the lampshade 4 not only makes the overall appearance of the landscape lamp more beautiful, but also the edge of the reflected light projected on the grass or landscape trees will have a corresponding lace effect, thereby making the night view of the grass and landscape trees more beautiful.

[0047] The implementation principle of this embodiment is: install the landscape lamp of this application in front of the green grass or landscape small tree with lighting, and when the lighting lamp 3 on the lamp holder 2 is lit at night, the light of the lighting lamp 3 will shine on the reflective coating inside the lampshade 4 through the light-transmitting hole 5 on the lamp holder 2, and the reflective coating inside the lampshade 4 can convert the light directly from the lighting lamp 3 into reflected light and shine on the corresponding green grass or landscape small tree under the guidance of the side wall of the lampshade 4, so as to achieve the lighting effect of the green grass or landscape small tree at night. In addition, the light emitted by the lighting lamp 3 can also pass through the opening in the middle of the top of the lampshade 4 upwards, and then shine on the reflective plate 7 at the top, and through the reflection of the reflective coating inside the reflective plate 7, the surrounding roads are also illuminated, so that pedestrians nearby can walk at night.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
