When the outside air enters the exhaust pipe, it will pass through the moisture absorption cage, so that the desiccant in the moisture absorption cage absorbs moisture in the air, reduces the moisture content of the gas in the installation frame, and thus reduces the probability of water mist forming on the light-transmitting plate on the side of the lamp beads. The gas entering the installation frame will change the internal atmosphere of the installation frame, replace the gas with temperature inside the installation frame, so that the gas with temperature is blown to the lower surface of the light-transmitting plate through the blowing pipe, thereby realizing the cleaning of the lower surface of the light-transmitting plate and reducing the probability of cold air blowing directly to the lower surface of the light-transmitting plate, thereby ensuring the cleanliness of the light-transmitting plate and thus ensuring the penetration quality of the light.

When the piston plate 1102 moves from top to bottom along the inner surface of the piston cylinder 1101, the coolant inside the piston cylinder 1101 will be discharged into the heat exchange tube 1106 through the bottom end of the discharge pipe 1105, and after circulating in the heat exchange tube 1106, it will flow back to the piston cylinder 1101 through the top of the return pipe 1107.

[0047] like Figure 2 , Figure 5 , Figure 7 , Fig.10 , Fig.11 , Fig.12 , Fig.14 , Fig.15 and Fig.17 As shown, the energy-saving street lamp also includes: a visibility sensor 3, which is installed below the lamp housing 1 and is used to detect the visibility of the environment; a light guide mechanism 8, which is installed in the installation frame 5 and is located below the lamp beads 7, and is used to change the irradiation range of the lamp beads 7. The light guide mechanism 8 is set to multiple groups, and each group of light guide mechanisms 8 includes a cylinder 801, a first light guide plate 804 and a second light guide plate 805. When the visibility of the environment is low, that is, when there is heavy fog, haze or heavy rain, the visibility sensor 3 feeds back a signal to the control board The control board controls the cylinder 801 in the light guide mechanism 8 to work, the output end of the cylinder 801 is fixedly connected to the magnetic plate 802, the adjacent surfaces of the first light guide plate 804 and the second light guide plate 805 are fixedly connected to the magnetic sheet 803, the magnetic sheet 803 and the magnetic sheet 802 have the same magnetic properties on the opposite sides, and the two magnetic sheets 803 installed on the first light guide plate 804 and the second light guide plate 805 have opposite magnetic properties on the opposite sides, the lamp beads 7 are arranged between the first light guide plate 804 and the second light guide plate 805 on the two adjacent light guide mechanisms 8, and each group of light guide mechanisms 8 also includes The light guide frame 810 is fixedly connected to the mounting frame 5, the partition frame 4 is installed on the top of the light guide frame 810, the end of the first light guide plate 804 is fixedly connected to the first connecting frame 806, the end of the second light guide plate 805 is fixedly connected to the second connecting frame 807, the first connecting frame 806 and the second connecting frame 807 both penetrate the light guide frame 810 and are slidably connected to the light guide frame 810, the bottom of the first connecting frame 806 is fixedly connected to the first rotating ring 808, the bottom of the second connecting frame 807 is fixedly connected to the second rotating ring 809, and the first rotating ring 808 is fixedly connected to the first connecting frame 806. 08 and the second rotating ring 809 are installed on the heat exchange tube 1106 and are rotatably connected to the heat exchange tube 1106. The outer surfaces of the first light guide plate 804, the second light guide plate 805, the light guide frame 810 and the heat exchange tube 1106 are sprayed with reflective materials, so as to realize the reflection and focusing operation of the light generated by the lamp bead 7.

At this time, the arrangement of the first light guide plate 804 and the second light guide plate 805 can ensure the illumination range of the street lamp. At the same time, the arrangement of the first light guide plate 804 and the second light guide plate 805 can reduce the spillage of the light emitted by the lamp bead 7, thereby reducing the spillage range of the light when the street lamp is illuminated, and further reducing the glare effect caused by the light spillage on personnel;

[0049] When the visibility sensor 3 detects that the visibility of the environment is low, that is, when there is heavy fog, haze or heavy rain, the visibility sensor 3 will feed back a signal to the control board, and the control board will control the cylinder 801 to work so that the cylinder 801 pushes the magnetic plate 802 to move downward and enter between the magnetic sheets 803, so that the magnetic sheets 803 move outward under the repulsive force of the magnetic plates 802, thereby driving the first light guide plate 804 and the second light guide plate 805 to rotate outward along the outer surface of the heat exchange tube 1106. In this process, the first connecting frame 806 will drive the first rotating ring 808 to rotate along the outer surface of the heat exchange tube 1106, and the second connecting frame 807 will drive the second rotating ring 809 to rotate along the outer surface of the heat exchange tube 1106. 06 is rotated, thereby changing the angle between the first light guide plate 804 and the second light guide plate 805, so that the first light guide plate 804 and the second light guide plate 805 located on both sides of the lamp bead 7 are moved toward the lamp bead 7, so that the first light guide plates 804 and the second light guide plates 805 in the same group are in an inverted "eight" shape, so that the light emitted by the lamp bead 7 is focused by the first light guide plate 804 and the second light guide plate 805 with changed angles, reducing the illumination range of the street lamp, thereby improving the penetration of the light emitted by the lamp bead 7, so that the light can illuminate the road environment more clearly, making it easier for people to clearly observe the road conditions and improving road safety.

[0050] The specific working principle of the present invention is as follows:

[0051] When the street lamp is in normal use, when the temperature sensor detects that the temperature inside the installation frame 5 is too high, the control board starts the motor 901 so that the shaft 902 drives the main bevel gear 903 to rotate, and drives the fan blades 904 to rotate at the same time. The rotation of the fan blades 904 will cause the connecting pipe 905 to produce a suction effect, so that the connecting pipe 905 extracts the gas inside the suction pipe 906, and the suction pipe 906 will extract the gas from the external environment. When the gas from the external environment enters the suction pipe 906, the dust contained in the external environment gas is first filtered by the dustproof net 909, and the filtered gas The body will pass through the moisture absorbing cage 907, and the desiccant in the moisture absorbing cage 907 will dry the gas, reduce the moisture content of the gas in the installation frame 5, thereby reducing the probability of water mist forming on the side of the light-transmitting plate 10 located on the lamp bead 7. The dried gas will enter the installation frame 5 through the connecting pipe 905, and after carrying the internal temperature of the installation frame 5, it will be blown to the lower surface of the light-transmitting plate 10 through the blowing pipe 912, thereby cleaning the lower surface of the light-transmitting plate 10 and reducing the probability of cold air blowing directly to the lower surface of the light-transmitting plate 10, ensuring the cleanliness of the light-transmitting plate 10, thereby ensuring the penetration quality of the light;

[0052] When the main bevel gear 903 rotates, the slave bevel gear 1103 will be driven to rotate, and then the reciprocating screw 1104 will be driven to rotate, so that the piston plate 1102 moves up and down on the inner surface of the piston cylinder 1101. When the piston plate 1102 moves from top to bottom along the inner surface of the piston cylinder 1101, the coolant inside the piston cylinder 1101 will be discharged into the heat exchange tube 1106 through the bottom end of the discharge pipe 1105, and after circulating in the heat exchange tube 1106, it will flow back to the piston cylinder 1101 through the top of the return pipe 1107. When the piston plate 1102 moves from bottom to top on the inner surface of the piston cylinder 1101, the coolant inside the piston cylinder 1101 will be discharged through the bottom end of the discharge pipe 1105. The top of the drain pipe 1105 is discharged into the heat exchange pipe 1106, and after circulating in the heat exchange pipe 1106, it flows back to the piston cylinder 1101 through the bottom of the return pipe 1107. When the coolant circulates in the heat exchange pipe 1106, it will carry the temperature of the environment where the lamp bead 7 is located, and cooperate with the air cooling operation of the ventilation mechanism 9 to achieve water cooling and air cooling of the environment where the lamp bead 7 is located, thereby reducing the temperature in the space where the lamp bead 7 is located, avoiding the situation where the temperature of the environment where the lamp bead 7 is located is too high, resulting in aging and discoloration of the lamp bead 7, and can also reduce the probability of aging of the circuit board 6 under temperature, thereby ensuring the quality of the light emitted by the lamp bead 7 and extending the service life of the street lamp;

[0053] When the street lamp is in normal use, the angle between the first light guide plate 804 and the second light guide plate 805 is in a proper "eight" shape under the magnetic attraction of the magnetic sheet 803. At this time, the setting of the first light guide plate 804 and the second light guide plate 805 can ensure the illumination range of the street lamp. At the same time, the setting of the first light guide plate 804 and the second light guide plate 805 can reduce the spillage of the light emitted by the lamp bead 7, thereby reducing the spillage range of the light when the street lamp is illuminated, and further reducing the glare effect caused by the light spillage on personnel; and when the visibility sensor 3 detects that the environmental visibility is low, that is, when there is heavy fog, haze or heavy rain, the visibility sensor 3 feeds back a signal to the control board, and the control board will control the cylinder 801 to work so that the cylinder 801 pushes the magnetic plate 802 to move downward and enter between the magnetic sheets 803, so that the magnetic sheet 803 moves outward under the repulsive force of the magnetic sheet 802, thereby driving the first light guide plate 804 and the second light guide plate 80 5 rotates outwardly along the outer surface of the heat exchange tube 1106. During this process, the first connecting frame 806 will drive the first rotating ring 808 to rotate along the outer surface of the heat exchange tube 1106, and the second connecting frame 807 will drive the second rotating ring 809 to rotate along the outer surface of the heat exchange tube 1106, so as to change the angle between the first light guide plate 804 and the second light guide plate 805, so that the first light guide plate 804 and the second light guide plate 805 located on both sides of the lamp bead 7 move toward the lamp bead 7, so that the first light guide plate 804 and the second light guide plate 805 of the same group form an inverted "eight" shape, so that the light emitted by the lamp bead 7 is concentrated by the first light guide plate 804 and the second light guide plate 805 with changed angles, reducing the irradiation range of the street lamp, thereby improving the penetration of the light emitted by the lamp bead 7, so that the light can more clearly illuminate the road environment, making it easier for people to clearly observe the road conditions and improving road safety.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
