Embodiment 1
[0023] like Figure 1-3 As shown, a municipal road traffic warning light includes a base 1, the upper end of the base 1 is fixedly connected with a threaded rod 2, the threaded rod 2 is a coarse thread, the thread lead angle is greater than the equivalent friction angle of the screw pair, and has no self-locking property , the upper end of the threaded rod 2 is fixedly mounted with an incandescent lamp 3, and the side wall of the threaded rod 2 is fixedly connected with a plurality of triangular prisms 4 through a support rod 12, the triangular prisms 4 are on the same level as the incandescent lamp 3, and the threaded rod 2 is externally threaded. There is a rotating sleeve 5, and a light shielding ring 6 is fixedly connected to the side wall of the rotating sleeve 5.
[0024] The shading ring 6 is set outside the prism 4, and the shading ring 6 is composed of a plurality of monochromatic transparent film plates 7. It should be noted that the monochromatic transparent film pl...
Embodiment 2
[0027] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that an annular shading strip 10 is fixedly sleeved on the outer wall of the shading ring 6, the annular shading strip 10 is made of a transparent flexible material, and the annular shading strip 10 is filled with chlorine Silver chloride crystals, silver chloride crystals decompose under strong light irradiation, the reaction equation is 2AgCl=2Ag+Cl 2 .
[0028] When being in the noon when the sun is strong, the silver chloride in the shading strip 10 is irradiated by strong light, and the silver in the crystal is separated, and the free silver forms small aggregates inside the shading strip, and these small The silver aggregates reflect sunlight in an irregular block shape, and then make the shading strip 10 black, which is in sharp contrast with the red and blue light emitted by the warning light, making the warning light more eye-catching, and making the warning light not easy to o...
Embodiment 3
[0030] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that: a fan 11 is arranged above the incandescent lamp 3 , and the end of each fan blade in the fan 11 away from the connecting shaft is fixedly connected to the inner wall of the light shielding ring 6 .
[0031] When the vehicle drives the wind to blow to the wing plate 9, according to Bernoulli's principle, when the flow is at a constant height, the flow velocity is high and the pressure is small, then the wing plate 9 is subjected to an upward force and drives the light shielding ring 6 to move upward. The effect of the rod 2, the rotating sleeve 5 drives the shading ring 6 to rotate, and the fan 11 rotates, which promotes the air circulation at the 3 places of the incandescent lamp, plays the effect of heat dissipation, and prolongs the service life of the incandescent lamp 3 .
