Description
Technical Field
The utility model belongs to the street lamp field, concretely relates to little LED street lamp of light pollution.
Background
The LED light source has low energy consumption and good lighting effect, and the high-power LED lighting lamp has great impact on the traditional lighting industry, however, the high-power LED light source has the problem of heat dissipation inevitably, and the energy waste is caused by using the high-power lamp for a long time.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a little LED street lamp of light pollution.
The utility model discloses a realize through following technical scheme: the utility model provides a LED street lamp that light pollution is little, includes hollow stand and fixes the hollow xarm in stand one side upper end, fixed lamp holder is installed through the support arm to the terminal bottom of extension of xarm, the slope is equipped with the rotary rod between stand and the xarm, install movable lamp holder on the rotary rod, the one end of rotary rod is passed the xarm, and insert to establish and fix in the bearing frame in the xarm, the other end of rotary rod passes the stand, and the cover is equipped with driven gear, driven gear and driving gear meshing, the driving gear cup joints on the output shaft of motor, the motor slope sets up in the stand.
The motor is a stepping motor.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a wrong peak differentiation illumination provides sufficient lighting condition on the one hand, and on the other hand effectively reduces the energy waste and light pollution.
Drawings
Fig. 1 is a first front view structural state diagram of the present invention;
fig. 2 is a second front view structural state diagram of the present invention.
In the drawings: 1. a column; 2. a cross arm; 3. fixing the lamp holder; 4. rotating the rod; 5. a movable lamp cap; 6. a bearing seat; 7. a driven gear; 8. a driving gear; 9. an electric motor.
Detailed Description
As shown in fig. 1 to 2 in the drawings of the specification, an LED street lamp with low light pollution includes a hollow upright post 1 and a hollow cross arm 2 fixed at the upper end of one side of the upright post 1, a fixed lamp cap 3 is installed at the bottom of the extending end of the cross arm 2 through a support arm, a rotating rod 4 is obliquely arranged between the upright post 1 and the cross arm 2, a movable lamp cap 5 is installed on the rotating rod 4, one end of the rotating rod 4 penetrates through the cross arm 2 and is inserted into a bearing seat 6 fixed in the cross arm 2, the other end of the rotating rod 4 penetrates through the upright post 1 and is sleeved with a driven gear 7, the driven gear 7 is meshed with a driving gear 8, the driving gear 8 is sleeved on an output shaft of a motor 9.
The motor 9 is a stepping motor, can achieve instant starting and stopping, and ensures the precision of a transmission stroke.
A street lamp controller is arranged in the upright post 1, the street lamp controller comprises a time control switch (the street lamp controller is a market universal device, is the prior art, and has the structure and the type of common general knowledge of technicians in the field), timing control can be carried out, and the street lamp controller is electrically connected with the motor 9.
The specific working principle is as follows: in the time of high peak of the pedestrian flow at night, the street lamp controller controls the fixed lamp holder 3 and the movable lamp holder 5 to be completely lighted, so that the street lamp controller has the advantages of wide illumination range and high illumination intensity and provides illumination for pedestrians; when the pedestrian volume is less, the street lamp controller controls the movable lamp cap 5 to be closed, and the control motor 9 is started to drive the rotating rod 4 to rotate, so that the movable lamp cap 5 rotates to the state shown in the figure 2, and the energy waste and the light pollution are effectively reduced while the illumination is provided for pedestrians.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
