Examples

As shown in FIGS. 1-2, a visible street lamp under haze for solve the problem that the street lamp that prior art provided can not effectively sign the position of street lamp pole in haze day, its structure includes: the LED lamp comprises a lamp panel, a lighting system, a street lamp pole, a laser mark, a scattering cavity and a euphotic layer, wherein the lamp panel is communicated with the lighting system and emits light after being powered on, the street lamp pole is used for supporting the lamp panel and keeping the height of the lamp panel, because the part is the prior art and is not described in detail, the laser mark emits a laser beam parallel to the street lamp pole, and the laser can be scattered to form a laser movement track to play a role in indicating the position of the street lamp pole by utilizing the characteristic of high parallelism of the laser when a large amount of dust is in the air, meanwhile, the emitted laser beam enters the scattering cavity after being reflected by the reflector 13, is emitted from the euphotic layer after being scattered by the scattering cavity, and is divided into a plurality of light rays in different directions after being scattered for a plurality of times, and jet out from the euphotic layer, the longer laser source of the higher wavelength of the higher penetrability in the haze is used in the collocation, makes things convenient for pedestrian or driver in the distance also can in time discover the position of light pole in the haze day.

The laser mark comprises a laser generator 11, an outer lens 12 and a reflector 13, the laser mark is arranged outside the street lamp pole, more than one laser mark is positioned around the street lamp pole, and the problem that the laser mark cannot be seen due to the angle problem is avoided; as shown in fig. 1, a laser generator 11 emits a laser beam parallel to the surface of a light pole, an outer lens 12 and a reflective mirror 13 are sequentially arranged along the light propagation direction, a biconcave lens is embedded in the outer lens 12, the frame of the outer lens 12 is fixed outside the light pole, the axis of the outer lens 12 coincides with that of the light pole, the laser beam can be dispersed, the laser beam has good directivity, the parallelism state of the laser beam is changed after passing through the concave lens, the light forming the laser beam is refracted to a certain degree, because more than one outer lens 12 has better scattering effect on the laser beam, and the laser beam is reflected by the reflective mirror 13 to enter a scattering cavity, the shell of the reflective mirror 13 is a square box body, wherein a plane reflective mirror 22 is obliquely arranged, the included angle between the plane reflective mirror 22 and the horizontal plane is 45 degrees, when the air quality is good, the particulate matters in the air are less, so the, therefore invisible, only under haze weather, the particulate matter in the air increases, and the particulate matter is located laser path and will partly laser external reflection for the laser beam can be seen by naked eye, and the light source colour that the laser beam adopted is the red light in addition, so has better haze penetrability for white light, can be seen by people in a distance, reaches the effect of sign light pole position.

The scattering cavity is positioned in a light pole, the scattering cavity is a cavity formed by two top surfaces which are fixed in the light pole and are arranged in parallel, a light transmitting layer is also arranged at a position close to the upper top surface and the lower top surface of the scattering cavity, the two top surfaces of the scattering cavity are made of transparent quartz glass, scattered light can penetrate through the top surfaces and enter the light transmitting layer, an opening connected with a reflector 13 is reserved on the side wall of the scattering cavity arranged on the light pole, laser reflected by the reflector 13 enters the scattering cavity through the opening for dispersion, each reflector 13 is correspondingly provided with a scattering cavity, therefore, laser marks on the same light pole are not on the same horizontal plane so as to conveniently place the scattering cavity, as shown in figure 1, the scattering cavity comprises an inner lens 21 and a reflector 22, the inner lens 21 is a biconcave lens, the inner lens 21 is vertical to the entering direction of the laser, more than one inner lens 21 is arranged in the scattering cavity in parallel, the laser is further diffused, a reflecting mirror 22 is arranged on the side face, opposite to the incident laser, in the scattering cavity, the reflecting mirror 22 is a convex reflecting mirror 22, the scattered laser beams can be reflected to the periphery, and the reflected laser beams can respectively enter the light transmitting layers on the upper side and the lower side of the scattering cavity.

As shown in fig. 2, the light-transmitting layer is located at the upper and lower sides of the scattering cavity, the side surface of the light-transmitting layer is also ground glass 31, a section of the light pole on which the light-transmitting layer is arranged is provided with a plurality of through holes, so that the light scattered in the light-transmitting layer can be emitted, the upper and lower bottom surfaces of the light-transmitting layer are ground glass 31 and a reflection plate 32, respectively, wherein the ground glass 31 is a top surface of the light-transmitting layer close to one side of the scattering cavity, the reflection plate 32 is a top surface of the other side, the light-transmitting layer is horizontally provided with a plurality of ground glasses 31, the rough surface of the ground glass 31 can make a part of the laser acted thereon diffuse-reflected, the other part of the laser acted on the ground glass 31 passes through the ground glass 31 and enters the ground glass 31 of the next stage to be scattered continuously, the reflection plate 32 is, after the light that is sent by diffuse reflection from the euphotic layer, through the reflection of haze granule, form the light group near the euphotic layer on light pole, because the colour of laser is obviously different with the colour of street lamp light source, the light group that consequently forms also can distinguish with the street lamp light source, in addition, still keep parallel light after the multiple scattering can jet out with the form of laser beam, there is farther visible distance in haze day, it observes more easily after combining with the laser mark, and effectively utilized the laser that laser generator 11 produced.

It is worth noting that: the through holes of the light-transmitting layer on the street lamp pole are mainly used for light emission, so that the shape of the light-transmitting layer is not necessarily a round hole shape, and a through groove with a specific shape can be formed, and the light-transmitting layer can be flexibly adjusted according to specific conditions in actual use.

Furthermore, a small amount of titanium dioxide powder is spread on the horizontal ground glass 31 in the light-transmitting layer, the titanium dioxide powder cannot completely cover the surface of the ground glass 31, so that the situation that light cannot penetrate through the ground glass 31 is avoided, the titanium dioxide powder is stable in property and white in surface, and light scattering is further accelerated.

This embodiment passes through the laser sign because of the characteristic that is visible by the scattering under haze weather, cooperation scattering chamber and euphotic layer jet out from the euphotic layer again after the laser scattering with the laser sign, make the light pole send ruddiness, ruddiness is stronger for the white light that the illumination was used, and penetrability in the haze is stronger, is seen by pedestrian or driver more easily to make the position of street lamp also visible in haze weather, make things convenient for the pedestrian driver to effectively dodge.
