[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0021] like Figure 1-10 As shown, an energy-saving street light with intelligent adjustable lighting area includes a lamp head, which includes a first LED lamp 21 and a second LED lamp 22 symmetrically and movably arranged on a support drive rod 1; The drive rod 1 is equipped with a long-stroke push-pull electromagnet 12 for pushing the first LED light 21 to move relative to the second LED light 22.

[0022] Specifically, the load-bearing drive rod 1 includes a connecting frame 10, a long-stroke push-pull electromagnet 12 is mounted on the connecting frame 10, and the first LED light 21 and the second LED light 22 are rotatably connected to the connecting frame 10. A connecting base frame 23 is mounted on the connecting frame 10, and a housing 20 is mounted on the connecting base frame 23. The housing 20 covers the first LED light 21 and the second LED light 22. The second LED light 22 is mainly used to illuminate the sidewalks and non-motorized vehicle lanes along the road. When the long-stroke push-pull electromagnet 12 is energized, it extends and pushes the first LED light 21, causing the first LED light 21 to deflect, thereby shifting the illumination area of ​​the first LED light 21 toward the target road (i.e., the first LED light 21 moves away from the second LED light 22), illuminating the center of the two roads.

[0023] In the above technical solution, the first LED light 21 is installed facing the road that needs to be illuminated. When it is necessary to turn off the street light on one side in the early morning for energy conservation and emission reduction, the long-stroke push-pull electromagnet 12 is activated to push and deflect the first LED light 21, so that the illumination area of ​​the first LED light 21 is shifted towards the target road and illuminates the center of the two roads. This compensates for the street light that is turned off on one side of the road. While saving energy, the visibility of the two roads is increased by adjusting the illumination area.

[0024] As one embodiment of the present invention, the first LED lamp 21 includes a wide lamp plate 211, which is tilted horizontally or at two constant angles as pushed by the long-stroke push-pull electromagnet 12.

[0025] Specifically, deflection plates 13 are symmetrically rotatably connected to the connecting frame 10. The rotatable connection can be a rotating hole set on the connecting frame 10, with two rotating holes rotatably connected to the connecting frame 10. The two deflection plates 13 are used to support the first LED light 21 and the second LED light 22, respectively. The first LED light 21 also includes a first lamp housing 210. The first lamp housing 210 and the wide lamp plate 211 are both set on the deflection plates 13. The long-stroke push-pull electromagnet 12 pushes against the deflection plates 13 to deflect, thereby driving the wide lamp plate 211 to deflect towards the target road. The wide lamp plate 211 has three fixed angular positions as the long-stroke push-pull electromagnet 12 pushes against it. When the wide lamp plate 211 is in a horizontal position, it provides normal lighting. When it is necessary to turn off one side of the streetlights for energy conservation and emission reduction, the long-stroke push-pull electromagnet 12 pushes against the deflection plates 13 to deflect and tilt. The tilt angle includes two constant positions. The first tilt angle is small and suitable for narrow roads. The second tilt angle is large and suitable for wide roads.

[0026] As one embodiment of the present invention, the second LED light 22 is pushed against by the long-stroke push-pull electromagnet 12 to move relative to the first LED light 21.

[0027] Specifically, the second LED light 22 is set on another deflection plate 13. When the long-stroke push-pull electromagnet 12 extends, the second LED light 22 will deflect away from the first LED light 21 along with the deflection plate 13, thereby moving closer to the sidewalk, non-motorized vehicle lane and other areas beside the road for illumination.

[0028] Furthermore, the second LED light 22 includes a second lamp housing 220 and a narrow lamp plate 221. Both the second lamp housing 220 and the narrow lamp plate 221 are mounted on the deflection plate 13 by fasteners (which can be screws). When the long-stroke push-pull electromagnet 12 pushes, the narrow lamp plate 221 will deflect with the deflection plate 13 to illuminate the sidewalk, non-motorized vehicle lane, etc. on the side of the road. Alternatively, when the pushing end 121 on the long-stroke push-pull electromagnet 12 changes position, the narrow lamp plate 221 will deflect with the deflection plate 13 to a horizontal state to illuminate the normal road and the sidewalk, non-motorized vehicle lane, etc.

[0029] The second LED light 22 and the first LED light 21 are connected in parallel to a power supply, and can be independently turned on or off, so as to temporarily turn one of the LED lights on or off as needed to save energy and reduce emissions.

[0030] Furthermore, reflectors 2111 are provided on both the narrow light panel 221 and the wide light panel 211, and the load-bearing drive rod 1 is fixedly connected to the light pole 3 by fasteners.

[0031] As an embodiment of the present invention, a connecting base 23 is provided on the load-bearing drive rod 1, and a reflective telescopic plate 231 is provided between the connecting base 23 and the first LED light 21.

[0032] Specifically, the reflector telescopic plate 231 has a pin hinged to the connecting base 23, allowing the reflector telescopic plate 231 to rotate. The other end of the reflector telescopic plate 231 is hinged to the first lamp housing 210 of the first LED lamp 21 via the pin. When the first LED lamp 21 deflects, it pulls the reflector telescopic plate 231 to extend or shorten, and the reflection angle of the reflector telescopic plate 231 increases with the continuous deflection of the first LED lamp 21. When the first LED lamp 21 is at an inclined angle, such as... Figure 5 As shown, the reflective telescopic plate 231 reflects part of the light from the first LED light 21, which serves to focus the light on the road. When it is tilted to illuminate the opposite road, it can still illuminate the road on its own side.

[0033] As an embodiment of the present invention, a limiting block 14 is provided at the output end of the long-stroke push-pull electromagnet 12. An inclined surface is provided on the limiting block 14, and an abutment rod 131 that is always in contact with the inclined surface is movably provided on the first LED light 21.

[0034] Specifically, the output end of the long-stroke push-pull electromagnet 12 is the push end 121. The push end 121 is equipped with an elastic element for pull-back. When the push end 121 of the long-stroke push-pull electromagnet 12 is energized, it extends out and when it is de-energized, it retracts. The deflection plate 13 is equipped with an abutment rod 131. The inclined surface on the limiting block 14 faces the deflection plate 13 on which the first LED light 21 is fixed. Due to the weight of the first LED light 21, the abutment rod 131 is always in contact with the inclined surface. When the push end 121 retracts, the abutment rod 131 is located at the lower position of the inclined surface. At this time, the first LED light 21 is in a horizontal state. When the push end 121 is energized and extends out, the abutment rod 131 is located at the higher position of the inclined surface, so as to drive the deflection plate 13 to deflect to the second tilt angle and adjust the lighting area of ​​the road.

[0035] The long-stroke push-pull electromagnet 12 is existing technology and will not be described in detail.

[0036] Furthermore, such as Figure 7 As shown, a high-point groove 151, a mid-position groove, and a low-point groove 152 are respectively formed on the inclined surface. A connecting channel 154 is formed between the high-point groove 151 and the low-point groove 152. When the pushing end 121 is energized and extends for the first time, the abutting rod 131 slides along the low-point groove 152 into the connecting channel 154 and enters the high-point groove 151. Then, the pushing end 121 retracts for the first time, causing the abutting rod 131 to enter the mid-position groove from the high-point groove 151. Immediately afterwards, the pushing end 121 pushes a second time to maintain the abutting rod. When the abutment rod 131 is in the middle slot, the second retraction of the push end 121 returns to the low slot 152 to complete the cycle; when the abutment rod 131 is in the low slot 152, the deflection plate 13 carrying the first LED light 21 is in a horizontal state; when the abutment rod 131 is in the high slot 151, the deflection plate 13 carrying the first LED light 21 is in the second tilt angle; when the abutment rod 131 is in the middle slot, the deflection plate 13 carrying the first LED light 21 is in the first tilt angle.

[0037] like Figure 7 As shown, the middle slot includes a first limiting angle 153 and a second limiting angle 155 that are connected. An inclined channel is provided between the first limiting angle 153 and the second limiting angle 155. The inclined channel is a slope channel that allows the abutment rod 131 to pass through in one direction only. The second limiting angle 155 is connected to the high point slot 151. When the abutment rod 131 enters the middle slot from the high point slot 151, it will enter the second limiting angle 155 along the channel and be restricted. When the pushing end 121 pushes for the second time, the abutment rod 131 will enter the first limiting angle 153 along the inclined channel and stay there. A ramp 156 connected to the low point slot 152 is provided on the first limiting angle 153. When the pushing end 121 retracts for the second time, the abutment rod 131 returns to the low point slot 152 along the ramp 156 to complete the cycle. The switching between the high point slot 151, the low point slot 152 and the middle slot is realized by the telescopic pushing end 121.

[0038] Furthermore, a horizontally oriented groove is provided on the deflection plate 13 used to support the second LED light 22 and the first LED light 21. An abutment rod 131 is slidably connected to the groove. Springs 132 are provided between the two ends of the abutment rod 131 and the groove. The springs 132 restrict the abutment rod 131 from approaching along the central axis of the limiting block 14, thereby assisting the abutment end 121 in switching between the high point groove 151, the low point groove 152 and the middle position groove during the extension and retraction process.

[0039] As the preferred embodiment provided by the present invention, a limiting block 14 is provided at the output end of the long-stroke push-pull electromagnet 12. An annular channel 161 is provided on the limiting block 14. The annular channel 161 includes a raised surface 162 and a lowered surface 163. An abutment rod 131 is provided on the second LED light 22 and is slidably connected to the annular channel 161.

[0040] Specifically, the side of the limiting block 14 facing the first LED light 21 is an inclined surface, and the side of the limiting block 14 facing the second LED light 22 is a vertical surface 16. The annular channel 161 is formed on the vertical surface 16, as shown below. Figure 9 As shown, the two joints of the raised surface 162 and the lowered surface 163 are provided with slopes to facilitate the switching of the abutment rod 131 between the raised surface 162 and the lowered surface 163. When the abutment rod 131 is in the lowered surface 163, the second LED light 22 is in a horizontal state. When the abutment rod 131 is in the raised surface 162, the second LED light 22 is in an inclined state. When the pushing end 121 pushes for the first time, the abutment rod 131 switches from the raised surface 162 to the lowered surface 163. When the pushing end 121 retracts for the second time, the abutment rod 131 switches from the lowered surface 163 to the raised surface 162.

[0041] Furthermore, the annular channel 161 can be equipped with a raised surface 162 and a lowered surface 163 at the midpoint of the vertical direction, thereby switching during the first retraction and the second push of the pushing end 121, and increasing the different states of the first LED light 21 corresponding to the tilt of the second LED light 22.

[0042] First, the first LED light 21 is installed facing the road that needs illumination. Then, during normal illumination, the long-stroke push-pull electromagnet 12 is not energized, the first LED light 21 is in a horizontal state for illumination, and the second LED light 22 is in an inclined state to cover the sidewalk next to the road. When it is necessary to turn off the street lights on one side for energy conservation and emission reduction, the long-stroke push-pull electromagnet 12 is energized, causing the pushing end 121 to extend and push out the limiting block 14, driving the first LED light 21 and the second LED light 22 to deflect and tilt. The first LED light 21 deflects to the opposite side of the road, thereby compensating for the street lights that are turned off on one side of the road, while the second LED light 22 switches to a horizontal state to compensate for the light of the moved first LED light 21.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
