Description

Technical Field

[0001] The present invention relates to the technical field of lighting devices, in particular to a street lamp with high light transmittance. Background Art

[0002] As the main equipment for urban road lighting, the normal operation of street lamps can ensure the normal operation of urban life. Most existing street lamps use LED lamp heads. In order to obtain a better lighting range, a light-transmitting mirror is usually equipped to diffuse the light beam to obtain a larger irradiation range. However, on rainy days, especially when the rainfall is large, the rainwater mixed with dust will fall on the surface of the light-transmitting mirror, resulting in the surface of the light-transmitting mirror being contaminated with dust, poor light-transmitting effect, and reduced brightness of the lamp head. Summary of the Invention

[0003] The purpose of the present invention is to provide a street lamp with high light transmittance. The present invention solves the problem that on rainy days, especially when the rainfall is large, the rainwater mixed with dust will fall on the surface of the light-transmitting mirror, resulting in the surface of the light-transmitting mirror being contaminated with dust, poor light-transmitting effect, and reduced brightness of the lamp head in existing street lamps.

[0004] The technical solution of the present invention is: a street lamp with high light transmittance, including a lamp body and a lamp post connected to the lamp body. The lamp body is connected with rain shields on both sides of the lamp post by a hinged manner. An angle control mechanism for controlling the rotation angle of the rain shield according to the rainfall is arranged at the top of the lamp body. The angle control mechanism includes a collection box, a driving link connecting the collection box and the rain shield, and a reset part for resetting the collection box. One end of the driving link is fixedly connected to the lower surface of the collection box, and the other end is movably connected to the rain shield through a sliding mechanism. The rain shield is provided with a chute for accommodating the sliding mechanism along the length extension direction.

[0005] Preferably, the sliding mechanism includes a drag plate hinged to the end of the driving link away from the collection box, absorbent cotton strips distributed on the side of the drag plate facing the rain shield, a support rod extending into the chute, a support plate arranged at the end of the support rod away from the drag plate, and a plurality of balls embedded on the surface of the support plate. Guide grooves slidably matched with the balls are arranged on both sides of the chute inside the rain shield, and a first drainage groove is arranged at the bottom of the guide groove.

[0006] Preferably, an inclined plate is arranged on the inner wall of the chute along the length extension direction of the rain shield, and the inclined plate inclines towards the support plate.

[0007] Preferably, second drainage grooves are arranged on the upper surface of the support plate on both sides of the support rod. The vertical distance from the end of the second drainage groove away from the support rod to the support rod is greater than the vertical distance from the end of the inclined plate away from the inner wall of the chute to the support rod.

[0008] Preferably, a water passing hole is provided at the bottom of the collection box.

[0009] Preferably, an elastic contraction band is connected between the rain shield and the lamp body.

[0010] Preferably, a splash-proof plate is provided at the upper end of the collection box, and the splash-proof plate is inclined towards the axial center line of the collection box.

[0011] Preferably, the reset part includes a positioning block provided at the center of the bottom of the collection box and having a cavity, a positioning column with one end penetrating through the bottom of the collection box and extending into the cavity, and a spring sleeved on the positioning column. The other end of the positioning column is fixedly connected to the top of the lamp body.

[0012] The beneficial effects of the present invention are as follows:

[0013] Compared with the prior art, after the collection box of the present invention collects rainwater, it moves towards the lamp body. The driving link drives the drag plate to apply pressure to the support rod, so that the ball slides in the guide groove, thereby making the rain shield rotate towards the surface of the light-transmitting mirror. The greater the rainfall, the greater the rotation angle of the rain shield, avoiding the rainwater mixed with dust from falling onto the surface of the light-transmitting mirror when the rainfall is large, resulting in dust adhering to the surface of the light-transmitting mirror, and improving the light transmittance.

[0018] The present invention will be further described below with reference to the accompanying drawings by way of examples.

[0019] This specific embodiment is only an explanation of the present invention and is not a limitation thereof. Those skilled in the art can make modifications to this embodiment without creative contributions according to their needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0020] Example, as Figures 1-4As shown in the figure, a street lamp with high light transmittance includes a lamp body 1 and a lamp post 2 connected to the lamp body 1. On both sides of the lamp body 1 corresponding to the lamp post 2, there are rain shields 3 connected by a hinge. At the top of the lamp body 1, there is an angle control mechanism 4 for controlling the rotation angle of the rain shield 3 according to the rainfall. By controlling the rotation angle of the rain shield 3 through the angle control mechanism 4, it is possible to prevent rain from falling on the surface of the light-transmitting mirror 101 and causing dust to adhere to the surface of the light-transmitting mirror 101, thereby improving the light transmittance. The angle control mechanism 4 includes a collection box 401 for receiving rainwater, a driving link 402 connecting the collection box 401 and the rain shield 3, and a reset part 403 for resetting the collection box 401. One end of the driving link 402 is fixedly connected to the lower surface of the collection box 401, and the other end is movably connected to the rain shield 3 through a sliding mechanism 5. The rain shield 3 is provided with a chute 301 along the length extension direction for accommodating the sliding mechanism 5.

[0021] Furthermore, the sliding mechanism 5 includes a drag plate 501 hinged to the end of the driving link 402 away from the collection box 401, absorbent cotton strips 505 distributed on the side of the drag plate 501 facing the rain shield 3 for removing rainwater on the surface of the rain shield 3, a support rod 502 extending into the chute 301, a support plate 503 provided at the end of the support rod 502 away from the drag plate 501, and a plurality of balls 504 embedded on the surface of the support plate 503. Corresponding to both sides of the chute 301 inside the rain shield 3, there are guide grooves 302 that slidably cooperate with the balls 504. The bottom of the guide groove 302 is provided with a first drainage groove 303. Preferably, the rain shield 3 in this embodiment is made of PVC material. On sunny days, the rain shield 3 and the lamp body 1 are on the same horizontal plane. On rainy days, after the collection box 401 collects rainwater, it moves towards the lamp body 1, and the drag plate 501 is driven by the driving link 402 to apply pressure to the support rod 502, causing the balls 504 to slide in the guide grooves 302, so that the rain shield 3 rotates towards the surface of the light-transmitting mirror 101. The greater the rainfall, the greater the rotation angle of the rain shield 3, preventing rain from falling on the surface of the light-transmitting mirror 101 when the rainfall is large and causing dust to adhere to the surface of the light-transmitting mirror 101, thereby improving the light transmittance.

[0022] Furthermore, along the length extension direction of the inner wall of the chute 301, there is an inclined plate 506 for preventing rainwater from entering the guide groove 302, and the inclined plate 506 is inclined towards the support plate 503.

[0023] Further, second drainage grooves 5031 are formed on the upper surface of the support plate 503 corresponding to both sides of the support rod 502. The vertical distance from one end of the second drainage groove 5031 away from the support rod 502 to the support rod 502 is greater than the vertical distance from one end of the inclined plate 505 away from the inner wall of the sliding groove 301 to the support rod 502, ensuring that the rainwater on the surface of the rain shield 3 enters the second drainage groove 5031 through the inclined plate 505 and is discharged through the first drainage groove 303, preventing rainwater from entering the guiding groove 302 and causing dust adhesion to the guiding groove 302, and improving the light transmittance of the rain shield 3 after turning.

[0024] Further, a water passing hole 4011 is provided at the bottom of the collection box 401. When the rainfall is small, rainwater basically does not fall onto the surface of the light-transmitting mirror 101, and the rainwater in the collection box 401 can be discharged in time through the water passing hole 4011, and the turning angle of the rain shield 3 is small. When the rainfall is large, the collection speed of the rainwater in the collection box 401 is much greater than the drainage speed of the water passing hole 4011, and the turning angle of the rain shield 3 is large, preventing rainwater from falling onto the surface of the light-transmitting mirror 101. After the rain stops, the rainwater in the collection box 401 can be discharged through the water passing hole 4011.

[0025] Further, an elastic contraction band 6 is connected between the rain shield 3 and the lamp body 1, and the elastic contraction band 6 can prevent rainwater from entering the surface of the light-transmitting mirror 101 through the gap between the rain shield 3 and the lamp body 1.

[0026] Further, a splash-proof plate 4012 is provided at the upper end of the collection box 401, and the splash-proof plate 4012 is inclined towards the axial center line of the collection box 401.

[0027] Further, the reset part 403 includes a positioning block 4031 provided at the center of the bottom of the collection box 401 and having a cavity 4032, a positioning column 4033 with one end penetrating through the bottom of the collection box 401 and extending into the cavity 4032, and a spring 4034 sleeved on the positioning column 4033. The other end of the positioning column 4033 is fixedly connected to the top of the lamp body 1. Preferably, both ends of the spring 4034 are fixedly connected to the bottom of the collection box 401 and the top of the lamp body 1 respectively. When the rainfall is large, the collection speed of the rainwater in the collection box 401 is greater than the drainage speed of the water passing hole 4011, and the collection box 401 collects a large amount of rainwater, and the spring 405 is in a compressed state. When the rainfall is small or the rain stops, the collection speed of the rainwater in the collection box 401 is less than the drainage speed of the water passing hole 4011, and the spring 405 gradually resets.
