DETAILED DESCRIPTION

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0030] like Figures 1 to 9 As shown, a modular street lamp with adjustable lighting effects described in this embodiment includes a lamp pole 10 and a street lamp module 20 installed on the top of the lamp pole 10;

[0031] The street light module 20 includes a lamp housing 21 fixedly mounted on the lamp pole 10, with track plates 22 fixedly mounted at both ends of the lamp housing 21, and multiple groups of lighting lamp groups arranged side by side are connected between the two track plates 22. Preferably, two groups of lighting lamp groups arranged side by side are connected between the two track plates 22; the track plates 22 are provided with track grooves 221 corresponding to each group of lighting lamp groups, and the two groups of track grooves 221 are arranged side by side on the track plates 22; the lighting lamp groups include a first lighting unit and a second lighting unit; the two ends of the first lighting unit and the two ends of the second lighting unit are respectively slidably connected to the corresponding track grooves 221; a driving assembly is also installed in the lamp housing 21, and the driving assembly is configured to simultaneously drive the first lighting unit of each lighting lamp group to move in the opposite direction synchronously and the second lighting unit to move in the opposite direction synchronously, so that the first lighting unit or the second lighting unit moves to the center position of the lamp housing 21.

[0032] Specifically, in actual application of the modular street lamp of this embodiment, the first lighting unit of one lighting lamp group is set as a weak light source, and the second lighting unit is set as a strong light source, and the first lighting unit of the other lighting lamp group is set as a strong light source, and the second lighting unit is set as a weak light source; initially, the strong light sources of the two lighting lamp groups are located at the center of the lamp housing 21, and the lighting effect of the street lamp module 20 is central focusing and outer flooding, such as Figure 3 As shown; if it is necessary to switch the lighting effect, the driving component works, the first lighting units of the two lighting lamp groups move in the same direction, and the second lighting units of the two lighting lamp groups move in the same direction, that is, the first lighting unit of one lighting lamp group moves toward the center of the lamp housing 21, and the second lighting unit moves from the center to the outside, and the first lighting unit of the other lighting lamp group moves from the center to the outside, and the second lighting unit moves toward the center of the lamp housing 21. With the cooperation of the track groove 221, the strong light source of the two lighting lamp groups is located on the outside, and the weak light source is located in the center. At this time, the lighting effect of the street lamp module 20 is center floodlighting and outer spotlighting, as shown in FIG. Figure 5 As shown, the lighting effect of the modular street lamp can be adjusted.

[0033] For example, when installed at an intersection with a traffic light, the modular street light is combined with the traffic light. When pedestrians pass through the zebra crossing, the lighting effect of the modular street light is adjusted to center spotlight and outer floodlight, thereby focusing the zebra crossing. When the zebra crossing is prohibited from passing, the lighting effect of the modular street light is adjusted to center floodlight and outer spotlight to facilitate the passage of vehicles.

[0034] When used in garden scenes, the lighting effect of the modular street lamp can be adjusted to focus the center and flood the outside to illuminate specific plants or decorations.

[0035] In this embodiment, a lighting lamp group is arranged in the lamp housing 21 to cooperate with the track groove 221 of the track plate 22, so that under the drive of the driving component, the lighting effect of the modular street lamp can be adjusted to flexibly switch the lighting effect according to the actual application environment requirements, and the structure is more flexible.

[0036] like Figures 2 to 5 , Figure 7 As shown, the modular street lamp described in this embodiment, in one embodiment, the first lighting unit includes a first lamp holder 2311 and a first light source 2312 installed on the first lamp holder 2311; first connecting shafts 2313 are provided at both ends of the first lamp holder 2311, the first lamp holder 2311 is lifted and connected with a connecting frame 2314, the connecting frame 2314 is connected to the driving assembly, and a tension spring 2315 is connected between the connecting frame 2314 and the first lamp holder 2311; the second lighting unit includes a second lamp holder 2321 and a second light source 2322 installed on the second lamp holder 2321; second connecting shafts 2323 are provided at both ends of the second lamp holder 2321; the second lamp holder 2321 is connected to the driving assembly, and the ends of the first connecting shaft 2313 and the second connecting shaft 2323 are movably embedded in the corresponding track groove 221.

[0037] Specifically, the first light source 2312 of one lighting group is a high-light LED, and the second light source 2322 is a low-light LED; the first light source 2312 of the other lighting group is a low-light LED, and the second light source 2322 is a high-light LED. When the driving component is working, the first light sources 2312 of the two lighting groups move in the same direction, and the second light sources 2322 move in the same direction. The first connecting shaft 2313 and the second connecting shaft 2323 move along the track groove 221 respectively, so as to adjust the lighting effect of the modular street lamp.

[0038] like Figures 3 to 6 As shown, the modular street light described in this embodiment, in one embodiment, the track groove 221 includes a first horizontal section 2211, a first inclined section 2212, a second horizontal section 2213 and a second inclined section 2214, both ends of the first inclined section 2212 are connected to one end of the second horizontal section 2213 and the first horizontal section 2211, and both ends of the second inclined section 2214 are connected to the other end of the second horizontal section 2213 and the first horizontal section 2211; the first inclined section 2212 and the second inclined section 2214 are symmetrically arranged, and the midpoint of the first horizontal section 2211 is collinear with the midpoint of the second horizontal section 2213; initially, the first connecting shaft 2313 is movably embedded in one end of the first horizontal section 2211, the tension spring 2315 is in a stretched state, and the second connecting shaft 2323 is movably embedded in the other end of the first horizontal section 2211.

[0039] Specifically, in order to facilitate explanation of this embodiment, Figure 6As shown, one end of the first horizontal segment 2211 is defined as point A, the other end of the first horizontal segment 2211 is defined as point B, the junction of the first inclined segment 2212 and the first horizontal segment 2211 is defined as point C, the junction of the second inclined segment 2214 and the first horizontal segment 2211 is defined as point D, the junction of the first inclined segment 2212 and the second horizontal segment 2213 is defined as point E, and the junction of the second inclined segment 2214 and the second horizontal segment 2213 is defined as point F;

[0040] When the lighting effect of the modular street lamp switches from the central spotlight and the outer floodlight to the central floodlight and the outer spotlight, the first connecting shaft 2313 of one lighting lamp group moves from the C point position. When the first connecting shaft 2313 corresponds to the first inclined section 2212, under the tension of the tension spring 2315, the first connecting shaft 2313 enters the first inclined section 2212 from the first horizontal section 2211, enters the E point position along the first inclined section 2212, and then moves to the F point position along the second horizontal section 2213, enters the second inclined section 2214 through the F point position, and enters the D point position along the second inclined section 2214, and the second connecting shaft 2323 of the lighting lamp group moves from the D point position along the first horizontal section 2211 to the C point position, thereby realizing the position exchange of the first light source 2312 and the second light source 2322 of the lighting lamp group; similarly, the first light source 2312 and the second light source 2322 of the other lighting lamp group exchange positions; thereby achieving the lighting effect adjustment;

[0041] If it is necessary to increase the lighting distance, the first connecting axis 2313 is moved from point C away from the center or toward the center until the first connecting axis 2313 moves to point A, and the second connecting axis 2323 is moved from point D toward the center or away from the center until the second connecting axis 2323 moves to point B, thereby increasing the distance between the first lighting unit and the second lighting unit in the same group.

[0042] like Figures 2 to 5 As shown, the modular street lamp described in this embodiment, in one embodiment, the driving assembly includes a driving plate 241, a driving motor 242 fixedly mounted on the driving plate 241, a transmission wheel 243 rotatably mounted on the driving plate 241, and a transmission belt 244 wound around the transmission wheel 243; the output end of the driving motor 242 is connected to one of the transmission wheels 243; the connecting frame 2314 is connected to the upper side of the transmission belt 244, and the second lamp holder 2321 is connected to the lower side of the transmission belt 244. Specifically, when it is necessary to adjust the lighting effect, the driving motor 242 drives the transmission wheel 243 to rotate, the transmission wheel 243 drives the transmission belt 244 to rotate, and the transmission belt 244 simultaneously drives the connecting frame 2314 and the second lamp holder 2321 to move synchronously in the opposite direction, thereby achieving the adjustment of the lighting effect.

[0043] like Figures 3 to 5 As shown, in the modular street lamp described in this embodiment, in one embodiment, there are four transmission wheels 243, which are distributed at four corners of the driving plate 241, and the transmission belt 244 is wound around the four transmission wheels 243. In this embodiment, by providing four transmission wheels 243, it is assumed that the first lighting unit and the second lighting unit will not interfere with each other when the positions are exchanged.

[0044] like Figures 2 to 5 , Fig. 9 As shown, in the modular street lamp described in this embodiment, in one embodiment, a reflector 25 is provided on the inner wall of the lamp housing 21; a third lighting unit is connected between the two ends of the first lighting unit and the second lighting unit of the same lighting lamp group; the third lighting unit includes a third light source 261, both ends of the third light source 261 are connected to a transmission frame 262, and both ends of the transmission frame 262 are provided with a strip-shaped sliding hole 2621; the first connecting shaft 2313 and the second connecting shaft 2323 respectively correspond to the strip-shaped sliding holes 2621 that movably penetrate the two transmission frames 262. Preferably, the third light source 261 can adopt an LED light source with different color, light intensity and light spot pattern from the first light source 2312 and the second light source 2322, so as to enrich the lighting effect of the modular street lamp.

[0045] Specifically, the reflector 25 reflects the light to improve the utilization rate of the light; when adjusting the lighting effect, the first connecting shaft 2313 and the second connecting shaft 2323 move along the track of the track groove 221 respectively. During the movement, the transmission frame 262 is driven to swing through the strip slide hole 2621, and the transmission frame 262 drives the third light source 261 to rotate, thereby adjusting the illumination range of the third light source 261.

[0046] Of course, when adjusting the lighting effect, the driving motor 242 can also be used to drive the transmission belt 244 to move a certain distance, so that the first connecting shaft 2313 moves to the midpoint of the second horizontal section 2213, and the second connecting shaft 2323 moves to the midpoint of the first horizontal section 2211. At this time, the first light source 2312, the second light source 2322, and the third light source 261 are located on the same vertical line. At this time, the third light source 261 is flipped 90 degrees, thereby achieving different lighting effects, and the structural adjustment is more flexible.

[0047] like Figures 3 to 6As shown, in the modular street lamp described in this embodiment, in one embodiment, the third light source 261 has a pin 2611; the track groove 221 also includes a vertical section 2215, and the vertical section 2215 is located on the line connecting the midpoint of the first horizontal section 2211 and the midpoint of the second horizontal section 2213; the pin 2611 is movably embedded in the vertical section 2215; the opening width of the vertical section 2215 is smaller than the diameter of the first connecting shaft 2313 and the diameter of the second connecting shaft 2323. In this embodiment, by providing the vertical section 2215, when the first lighting unit and the second lighting unit are exchanged in position, the pin 2611 of the third light source 261 moves along the vertical section 2215, and is turned over under the joint action of the first connecting shaft 2313 and the second connecting shaft 2323. After the first lighting unit and the second lighting unit are exchanged in position, the third light source 261 is turned over by 180 degrees, and the light emitted by the third light source 261 is irradiated on the reflector 25, and is emitted after being reflected by the reflector 25.

[0048] like Figure 1 As shown, in the modular street lamp of this embodiment, in one embodiment, two street lamp modules 20 are symmetrically installed on the top of the lamp pole 10. This embodiment provides a larger illumination range by setting two street lamp modules 20.

[0049] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
