The invention provides a street lamp capable of adjusting an irradiation angle, aiming at adjusting the irradiation angle of the street lamp according to the speed of an automobile, so that the irradiation light is always positioned in front of the automobile and the normal running of the automobile is not influenced, and the street lamp is particularly suitable for the street lamps with small irradiation angle, large irradiation brightness and long irradiation distance, because the prior street lamp irradiates at a large angle but irradiates on a road surface with small brightness, the interval between two adjacent street lamps cannot be too far, usually is thirty to fifty meters, the conventional street lamp is used for the road surface with large traffic flow, for rural lanes and village and town roads, the traffic flow is very small at night, if the street lamp which is the same as an urban road is still adopted and is lightened all night, the street lamp is very wasteful and has no need, therefore, the invention designs a novel street lamp which is specially used for the road with small traffic flow, the street lamp of this application just like the searchlight, can shine very far, although shine the angle little, the luminance that shines the road surface is big, so can set up one very far apart, for example 100 meters to 200 meters set up a street lamp, compare current street lamp arrangement form like this, the street lamp quantity that not only the road of same length was arranged is few, the electric energy has been practiced thrift, and the cost of street lamp expense has also been reduced, power consumption has also been few, the key still does not influence and provides road lighting service for the car, application prospect is very wide.

Referring to fig. 2, in an embodiment of the invention, the illumination angle adjustable street lamp includes a lamp post 1 and a lamp body 5 disposed on the lamp post 1, the lamp body 5 is connected with the lamp post 1 in a rotating way, the lamp body 5 or the lamp post 1 is provided with a motor 8 for driving the lamp body 5 to rotate, the lamp body 5 is also provided with a vehicle speed measuring device 4, a central processing unit 2 and a controller 3, the central processing unit 2 sends a control instruction to the controller 3 according to a vehicle speed signal obtained by the vehicle speed measuring device 4, the controller 3 controls the motor 8 to rotate, the motor 8 rotates to drive the lamp body 5 to rotate to adjust the irradiation angle, because the speed information is known by the CPU 2, the CPU 2 controls the rotation speed of the motor 8 to match the speed, so as to ensure that the illuminating light is always in front of the driving direction of the vehicle, namely, the moving speed of the light illuminating the road surface by the street lamp is synchronous with the vehicle speed.

In this embodiment, generally, the range of the street lamps irradiated on the road surface is different according to the speed limit of the road, and for a rural town road with the speed limit of 50km/h, the range of the light irradiated on the road surface by the street lamps is 5-30 meters ahead of the automobile, and as the speed limit of the road is higher, the range of the light irradiated on the road surface by the street lamps is larger.

As shown in fig. 1, the arrow direction in the figure indicates the driving direction of the automobile, the first street lamp and the second street lamp are sequentially positioned in front of the driving direction of the automobile, each street lamp is provided with a vehicle speed measuring device 4, the central processor 2 sends a control instruction to the controller 3 when the vehicle speed measuring device 4 does not measure that the automobile passes through at ordinary times, the controller 3 controls the motor 8 not to rotate, and the central processor 2 also controls the street lamps not to be on;

when a vehicle passes by, once the vehicle speed information is measured by the vehicle speed measuring device 4, the central processing unit 2 controls the first street lamp to be lightened, the initial irradiation position of the first street lamp is shown as an irradiation area I17 in fig. 1, meanwhile, the central processing unit 2 sends a control instruction to the controller 3 according to the vehicle speed information, and the controller 3 controls the motor 8 to rotate, so that the irradiation area I17 and the vehicle move rightwards at the same speed, namely the moving speed of a bright area irradiated on a road surface by the street lamp is synchronous with the vehicle speed, and the street lamp can provide illumination service for the driving of the vehicle normally;

when the first illumination area 17 moves to the right to reach the position of the second illumination area 18, the illumination angle of the first street lamp is adjusted to be the maximum, then the illumination angle of the first street lamp moves to the left to return to the first illumination area 17, meanwhile, the automobile enters the second illumination area 18, the automobile speed measuring device 4 of the second street lamp detects the automobile speed information, and the second street lamp starts to replace the first street lamp to provide illumination service for the automobile, and so on.

In this embodiment, the illumination angle of the street lamp is adjusted in the direction shown by the arc arrow of the first street lamp in fig. 1, and as the automobile moves to the right, the illumination area rotates counterclockwise.

In this embodiment, as long as the car remains to travel at the uniform velocity all the time, the street lamp of this application just can normally be the road lighting service that the car provided, does not influence the car and normally travels.

In this embodiment, the counterclockwise rotation of the irradiation region is achieved by driving the lamp body 5 to rotate by the motor 8, as shown in fig. 2 and fig. 3, the lamp post 1 and the lamp body 5 are connected by the sleeve 6, the sleeve 6 is detachably and fixedly connected with the lamp post 1, the sleeve 6 is tightly sleeved with the gear ring 7, the motor 8 is installed on the lamp body 5 and is in transmission connection with the gear ring 7, the output shaft of the motor 8 is engaged with the gear ring 7 by a gear, and when the motor 8 rotates, the motor 8 can push the lamp body 5 to rotate around the gear ring 7; the sleeve 6 is internally inserted with a rotary drum 10 in a rolling manner, the lamp body 5 is rotatably connected with the sleeve 6 through the rotary drum 10, and the rotary drum 10 is fixedly connected with the lamp body 5.

In the present embodiment, as shown in fig. 1, the counterclockwise rotation angle of the irradiation area does not exceed 180 degrees, and is preferably 120 degrees, as shown in fig. 2 and 3, the moving speed of the bright area irradiated on the road surface by the street lamp can be synchronized with the vehicle speed by controlling the rotation speed of the motor 8, and the irradiation area can be returned to the counterclockwise rotation or the clockwise rotation by controlling the motor 8 to rotate forward and backward.

In the embodiment, in order to prevent impurities from falling on the gear ring 7 to affect the meshing transmission with the motor 8, a protective cover 9 is sleeved outside the gear ring 7, and as shown in fig. 3, the protective cover 9 can be fixedly connected with the sleeve 6 or the lamp body 5.
