Detailed Description
The embodiments of the present application will be described in conjunction with the drawings in the embodiments of the present application, and it is to be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When an element is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. The terms "top", "bottom", as used herein "
The terms upper, lower, left, right, front, rear, and the like are used for descriptive purposes only.
Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1 to 3, the present application provides a street lamp 100, which includes a lamp post 10 and a first lamp cap 20 disposed on the lamp post 10. Further, the first lamp cap 20 includes a first lamp housing 21 and a first light-emitting member 22 disposed in the first lamp housing 21, the first light-emitting member 22 is used for emitting light, and the light passes through the first lamp housing 21 to illuminate the external environment.
In one embodiment, the first lamp housing 21 is a glass housing.
In one embodiment, the first light emitting element 22 is composed of at least two switchable beads with different colors.
Further, referring to fig. 1 to 3, in order to prevent the light emitted from the first light-emitting element 22 from being irradiated on the light-tight cover at the upper end along the vertical direction and being absorbed by the light-tight cover, the first lamp holder 20 further includes a mounting base 23. Specifically, one end of the mounting seat 23 is fixed on the lamp post 10, the first lampshade 21 is fixed on the other end of the mounting seat 23 opposite to the lamp post 10, and the mounting seat 23 has a first surface 23a facing the first light-emitting element 22, so that when the light emitted by the first light-emitting element 22 irradiates on the first surface 23a, the first surface 23a can reflect the light out, so as to prevent the light-tight cover from absorbing the light and reducing the reflected amount of the light. Preferably, the first surface 23a is a bright surface with high light reflection performance, and may be formed by silver plating on an end surface of the mounting base 23 near one end of the first light-emitting member 22.
Referring to fig. 6, in order to change the direction of the light reflected by the first lampshade 21, the street lamp 100 further includes a first light adjusting film 24. Specifically, the first light adjusting film 24 includes a first conductive layer 241, a liquid crystal layer 242, and a second conductive layer 243 which are sequentially stacked. The first conductive layer 241 or the second conductive layer 243 is attached to the first lamp cover 21, a plurality of liquid crystals 242a are disposed in the liquid crystal layer 242, each liquid crystal 242a has a second surface 242b facing the first light-emitting device 22, and the second surface 242b of each liquid crystal 242a is coated with a silver foil layer 242c, so that when the liquid crystal layer 242 is subjected to a voltage to force the liquid crystal 242a to turn and drive the silver foil layer 242c to turn, the silver foil layer 242c deflects to different orientations, and when receiving light irradiated by the first light-emitting device 22 at the location, the light is reflected to the corresponding location.
Referring to fig. 6-9, the lc layer 242a can further rotate between a first position a and a second position B of the lc layer 242. Preferably, when the lc 242a is located in the first position a, the silver foil layers 242c are parallel to the inner surface of the first lampshade 21, and at this time, all the silver foil layers 242c surround to form a reflective surface 242d and wrap the first light-emitting element 22, and when the first light-emitting element 22 emits light, the light emitted by the first light-emitting element 22 irradiates the ground near the position right below the first light-emitting element 22 through the reflective surface 242d. At this time, the conductive molecule 242a is in the first state.
It should be noted that, due to the high density arrangement of the liquid crystals 242a in the liquid crystal layer 242, when the plurality of liquid crystals 242a are located at the first position a, the plurality of liquid crystals 242a are in close contact with each other, i.e., the silver foil layers 242c on the plurality of liquid crystals 242a are connected end to form a seamless reflective surface 242d.
Further, referring to fig. 7, fig. 7 is a reflection diagram of the light emitted from the first light-emitting device 22 on the reflective surface 242d when the plurality of liquid crystals 242a are located at the first position a. When the plurality of liquid crystals 242a are located at the first position a to form a seamless reflective surface 242d, the light emitted from the first light-emitting device 22 passes through each portion of the reflective surface 242d and finally exits through the transparent cover 27 toward the lower end of the first lamp cap 20, in conjunction with fig. 4, that is, when the plurality of liquid crystals 242a are located at the first position a, the light directly irradiates the end of the crosswalk 300.
Further, referring to fig. 8-10, fig. 8-10 show a schematic diagram of the dimming film 24 and a light ray diagram of the light emitted by the dimming film 24 and the first light emitting device 22 and the second light emitting device after the light ray is reflected by the silver foil layer 242c when the plurality of liquid crystals 242a are in the second position B. As can be seen, when the plurality of liquid crystals 242a are located at the second position B, the silver foil layers 242c on the plurality of liquid crystals 242a cannot be connected to form a complete reflective surface 242d, i.e., a gap is formed between each of the liquid crystals 242 a. Referring to fig. 10, when the liquid crystal 242a is located at the second position B, the light emitted from the first light-emitting element 22 is irradiated on the silver foil layer 242c on each liquid crystal 242a, and the light is reflected by the silver foil layer 242c and then diffused outward from the gap, and the light is shifted outward in the transverse direction compared with the case where the light is emitted downward along the light-transmitting cover 27. That is, when the plurality of lc 242a are located at the first position a, the light is irradiated from the transparent cover 27 to the head and tail ends of the crosswalk 300, and when the angle of the plurality of lc 242a is adjusted to the second position B, the light is reflected by the silver foil layer 242c on the plurality of inclined lc 242a to be laterally shifted to be irradiated to the central area of the crosswalk 300. Still further, the first light-emitting component 22 is formed by combining at least two lamp beads with different colors, and can be switched. In one embodiment, the first light-emitting component 22 is formed by combining red light bulbs and light yellow light bulbs, and the two different color bulbs are connected with the traffic street lamp signal at the crosswalk 300. Further, the red light beads are connected with the red light and the yellow light of the traffic signal lamp, so that when the red light and the yellow light at the crosswalk 300 are on, the red light beads in the first light-emitting member 22 are on, and the first light-emitting member 22 emits red light. At this time, the plurality of liquid crystals 242a are controlled to be at the first position a, that is, the plurality of silver foil layers 242c are connected to form a reflective surface 242d parallel to the inner side surface of the first lamp shade 21 as shown in fig. 7, the reflective surface 242d directly irradiates the red light emitted by the first light emitting element 22 to the end of the pedestrian crossing 300 through the transparent cover 27, so as to warn the passing pedestrian that the passing pedestrian is in a red light state at this time and is prohibited from passing, thereby avoiding the potential safety hazard caused by the false red light running of the pedestrian due to fatigue or lack of concentration. It is understood that the combination of the beads in the first light-emitting element 22 is not limited thereto, and as another embodiment, the first light-emitting element 22 can also be formed by combining a plurality of hybrid lights of red light, yellow light, green light, and the like.
Further, the amber light bead in the first light-emitting component 22 is connected with the green light at the crosswalk 300, so that when the traffic signal light at the crosswalk 300 is switched to the green light, the street lamp 100 controls the amber light bead to emit light. At this time, the voltage supply system in the street lamp 100 supplies power to the first conductive layer 241 and the second conductive layer 243, and forms an electric field surrounding the liquid crystal layer 242 between the first conductive layer 241 and the second conductive layer 243, and adjusts the shift of the plurality of liquid crystals 242a in the liquid crystal layer 242 by adjusting the strength of the electric field, so that the plurality of liquid crystals 242a are shifted to the second position B as shown in fig. 9 and 10. At this time, the silver foil layers 242c of the plurality of liquid crystals 242a laterally diffuse the light so that the light can be irradiated to the middle portion of the pedestrian crossing 300 to remind passers-by that the green light can pass through at this time, and to provide illumination for passers-by, thereby preventing the problem that the pedestrian crossing 300 is difficult to walk or falls and collides due to insufficient light.
It should be noted that, in an embodiment, the voltage supply system applies voltages with opposite polarities to the first conductive layer 241 and the second conductive layer 243, and the lc cell 242a is made of a positive liquid crystal material. When voltages with opposite polarities are applied to the first conductive layer 241 and the second conductive layer 243 through the voltage supply system, an electric field pointing to one conductive layer along the other conductive layer is generated at the liquid crystal layer 242a between the first conductive layer 241 and the second conductive layer 243, and at this time, the liquid crystal layer 242a is driven by the electric field to shift the silver foil layer 242c in the liquid crystal layer 242.
More specifically, in an initial state, that is, when no voltage is applied to the first and second conductive layers 241 and 243, the lc bulk 242a is in a first state, and the lc bulk 242a located in the lc layer 242 is located as shown in fig. 6. At this time, the reflective surface 242d on which the silver foil layer 242c on the lc 242a is disposed is parallel to the inner side of the first lampshade 21, so as to reflect the light emitted from the first light-emitting device 22 to the head and tail ends of the crosswalk 300. In the second state, that is, when a voltage is applied to the first conductive layer 241 and the second conductive layer 243, the first conductive layer 241 and the second conductive layer 243 generate an electric field at the liquid crystal layer 242 therebetween, the electric field controls the plurality of liquid crystals 242a to drive the silver foil layer 242c to shift to the position shown in fig. 8 and 9, and at this time, the light emitted from the first light-emitting element 22 is reflected to the middle portion of the crosswalk 300 through the plurality of silver foil layers 242 c.
It can be understood that the liquid crystal 242a is affected by the electric field to generate the offset effect, and when the strength of the electric field is different, the offset angle of the liquid crystal 242a is different, so that the present application can change the magnitude of the electric field generated at the liquid crystal layer 242 by changing the magnitude of the voltage input to the first conductive layer 241 and the second conductive layer 243, thereby changing the offset angle of the liquid crystal 242a, controlling the offset angle of the silver foil layer 242c, and reflecting the light emitted by the first light-emitting device 22 outward to a specific position at different angles.
It should be noted that the street lamp 100 further includes a control system (not shown), a circuit board (not shown), a voltage supply system (not shown), and some electronic components, so as to meet the normal power supply and voltage supply requirements of the electronic components in the street lamp 100.
Further, when the silver foil layers 242c are in the second state, the included angle between the plurality of silver foil layers 242c and the vertical plane is 60 ° -80 °, so as to focus the yellowish light emitted by the yellowish lamp beads, and reflect the yellowish light to the middle of the crosswalk 300, so as to prevent the problem that the light is difficult to focus due to the fact that the light is reflected too close to cause the crosswalk 300 is locally dark and the light is reflected too far. Preferably, the plurality of silver foil layers 242c have an angle of 70 ° with respect to the vertical plane, but obviously is not limited thereto, and as in another embodiment, the angle may also be 60 °, 62 °, 64 °, 66 °, 68 °, 72 °, 74 °, 76 °, 78 °, 80 °, and so on.
It should be noted that, because the plurality of liquid crystals 242a in the liquid crystal layer 242 are uniformly distributed in the liquid crystal layer 242, when the included angle between each silver foil layer 242c and the vertical plane is 0 ° to 60 °, the light is irradiated in the horizontal direction and reflected by each silver foil layer 242c, and then is irradiated to a short distance from the end of the crosswalk 300, so that a dark area where the light cannot be irradiated is easily generated at the crosswalk 300, thereby affecting the normal walking of pedestrians. For example, in one embodiment, when the angle between the silver foil layer 242c and the vertical plane is 45 °, the light will irradiate on the ground in the vertical direction when the light horizontally irradiates on the silver foil layer 242 c. It is understood that as the angle of the silver foil layer 242c with the vertical plane gradually increases, the incident angle of light parallel to the silver foil layer 242c gradually increases, and the reflection angle thereof gradually increases and gradually approaches the crosswalk 300. And when the angle between the silver foil layer 242c and the vertical plane is 90 °, i.e. parallel to the horizontal plane, the light directly passes through the gaps between the plurality of liquid crystals 242a and irradiates on the road surface, thereby causing the problem of light focusing, therefore, the following table conclusion can be obtained through the above-mentioned experiments, as can be seen from the following table:
irradiation effect of included angle between silver foil layer and vertical surface
