Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1-4, a dazzle various LED and bury lamp based on dispersion principle, including shell body 1 and interior casing 2, the cross-section of shell body 1 and interior casing 2 all is the U-shaped setting of invering, interior casing 2 sets up inside shell body 1, the lower bottom surface of interior casing 2 is equipped with LED fluorescent tube 3, the fixedly connected with soft board 4 of port department of interior casing 2, soft board 4 enables the light that LED fluorescent tube distributed out more softly, avoids light to penetrate people's eye directly and causes the discomfort.
Be equipped with in the reservoir bag 10 and dazzle various mechanism, it is specific, dazzle various mechanism including setting up three on every rotating plate 11 about the sliding tray 13 of rotating plate 11 centre of a circle central symmetry, all sliding connection has the vaulting pole 14 of level setting jointly in the sliding tray 13 that corresponds on every two rotating plates 11, fixedly connected with reset spring 15 between the both ends of every vaulting pole 14 and the lateral wall of corresponding sliding tray 13, when stepping on layering 6 and being stepped on and drive rotating plate 11 and rotate, vaulting pole 14 can prop cylindric reservoir bag 10 into the triangular prism form, become multiple colour with the light dispersion that LED fluorescent tube 3 sent, in rotating plate 11 rotation process, dispersed light can also change because of the difference of incident angle, the rendering effect to the environment is better.
A reset mechanism is arranged in the transmission cavity 5, it should be noted that the reset mechanism comprises a permanent magnet 16 fixedly connected to the lower end of the rack 9, a magnet block 17 with opposite poles repelling to the permanent magnet 16 is fixedly connected to the inner bottom surface of the transmission cavity 5, and the magnet block 17 can play a reset role on the rack 9.
The invention can be illustrated by the following operating modes:
when the underground lamp is lighted, the water in the water storage bag 10 absorbs the heat in the lamp body, and the water conducts heat with the air to perform primary heat dissipation.
When the pedestrian steps on to press and steps on layering 6, rack 9 of downward removal can drive axis of rotation 7 rotation under gear column 8's transmission effect, axis of rotation 7 can drive rotor plate 11 and rotate, vaulting pole 14 on the rotor plate 11 can outwards slide in sliding tray 13 under the effect of centrifugal force, thereby prop cylindric water storage bag 10 into the triangular prism form, because in the triangle-shaped and the circle of the same girth, triangle-shaped's area is littleer, consequently, the volume of whole water storage bag 10 can diminish, unnecessary water can be crowded in cooling tube 12, the area of contact of water with the air has been increased, further the heat dissipation carries out.
When the support rod 14 supports the cylindrical water storage bag 10 into a triangular prism, light emitted by the LED tube 3 is dispersed into a plurality of colors, and in the process of rotating the rotating plate 11, the dispersed light can be changed due to different incident angles, so that the rendering effect on the environment is better.
After the pedestrian leaves, the rack 9 can be reset by moving upwards due to the repulsive force between the permanent magnet 16 and the magnet block 17, when the rotating plate 11 stops rotating, the stay bar 14 can move towards the center of the rotating plate 11 under the elastic action of the return spring 15 to reset, the water in the radiating pipe 12 can be sucked back by the water storage bag 10, and the water in the water storage bag 10 and the radiating pipe 12 forms one-way flow, so that the radiating effect is enhanced.
Example 2
As shown in fig. 5 to 6, the present embodiment is different from embodiment 1 in that: the resetting mechanism comprises two sliding rods 18 arranged below the water storage bag 10, each sliding rod 18 is connected with the side wall of the inner shell 2 in a sliding mode, two ends of each sliding rod 18 are fixedly connected with connecting ropes 19, the other end of each connecting rope 19 extends into the transmission cavity 5 and is fixedly connected with the lower side wall of the rack 9, and elastic shading cloth 20 is fixedly connected between each sliding rod 18 and the side wall of the inner shell 2.
In this embodiment, when stepping on layering 6 and being stepped on and drive rack 9 and remove downwards, three vaulting poles 14 prop into the in-process of triangular prism form with water storage bag 10, rack 9 lower extreme can stimulate downwards and connect rope 19, make two slide bars 18 remove to the middle part of inner housing 2 under the pulling of connecting rope 19, pull out elasticity shading cloth 20, elasticity shading cloth 20 can shelter from partial light, the light that makes LED fluorescent tube 2 send is the strip and penetrates the water storage bag 10 directly, the dispersed influence of astigmatism to water storage bag 10 has been avoided, it is better to make the light effect of dazzling.
When the pedestrian leaves, the two sliding rods 18 will move towards the two sides under the elastic action of the elastic shading cloth 20, thereby driving the rack 9 to reset through the connecting rope 19.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
