A rotating shaft 11 is vertically arranged in the support 5, a brightness compensation plate 6 is arranged on the periphery of the rotating shaft 11, the brightness compensation plate 6 is fan-shaped, and the fan-shaped brightness compensation plate 6 can be rotatably collected into the support 5 along the rotating shaft 11. The support is accommodated on the surface of the lamp housing 3 by the rotating shaft 11, so that the use space is not occupied, and the compensation amplitude is adjustable.
The lighting module is internally provided with a first acquisition unit, a judgment unit, a second acquisition unit and an adjustment unit which are sequentially connected, wherein the first acquisition unit is used for acquiring the brightness value of the current environment, the judgment unit is used for judging whether the acquired brightness value is smaller than a threshold value, the second acquisition unit is used for acquiring the dynamic distance between the current lighting lamp bead and a receiver, and the adjustment unit adjusts and compensates the brightness of the lamp according to the acquired distance value.
In this embodiment, the brightness sensor 8 is used for detecting the current environment brightness value, and the terminal power supply at the top end of the lamp post 1 is turned on to enable the brightness sensor 8 to be in a working state, so as to detect the current environment brightness value, that is, step S1. Because luminance sensor 8 is located lighting lamp pearl 4 tops, it can be according to lighting lamp pearl 4 light brightness automatic adjustment lighting lamp pearl 4 luminance of present place, brings the best visual effect for the person of being accepted. The brightness sensor 8 consists of two components, namely a light projector and a light receiver, the light projector focuses light emitted by the illuminating lamp beads 4, the light is transmitted to the light receiver and then to the receiving inductor, the receiving inductor converts received light signals into electric signals, and the electric signals are subjected to different switching and control actions in the next step.
After the current environment brightness value is obtained, the current environment brightness value is compared with a threshold value, and the controller 10 executes an operation step after a corresponding comparison result, that is, step S2, where the threshold value is the minimum and maximum brightness values that can be accepted by human eyes in the current range, that is, the brightness requirement of the user is met in the brightness environment within and greater than the threshold value. If the current environment brightness value is 80Lux and the threshold value is 100Lux, determining that the current environment brightness value is smaller than the threshold value, and executing step S3; if the current environment brightness value is 150Lux and the threshold value is 100Lux, it is determined that the current environment brightness value is greater than the threshold value, and step S5 is executed. Wherein, the threshold value is obtained according to the following steps: 1) taking the lamp post as the center of a circle and taking the single irradiation length of the lamp bead as the radius to form a visible total area; 2) dividing the visible total area into a plurality of small areas and marking the small areas as corresponding coordinates; 3) when the minimum brightness and the maximum brightness of the illuminating lamp beads are adjusted, the minimum brightness and the maximum brightness appear when corresponding to coordinate points in a plurality of small areas; 4) the minimum and maximum brightness values of the neutralization measurement are marked as corresponding region thresholds.
When the ambient brightness value is smaller than the threshold value, the distance between the current lighting bead 4 and the user is obtained through the distance sensor 9, that is, step S3. The distance sensors 9 are also called displacement sensors, are arranged on two sides of the illuminating lamp bead 4, and are divided into laser distance sensors and ultrasonic distance sensors according to the measuring principle. The distance sensor 9 is generally composed of two elements, which are disposed at a set angle, one of which emits a short light pulse, and when the object is close enough, the object to be detected reflects infrared rays onto the other detecting element, and the distance to the object is calculated by measuring the time from the emission of the light pulse to the reflection of the light pulse by the object. If the distance sensor 9 detects that the distance value between the current lighting lamp bead 4 and the user can be 1 meter, 2 meters, 3 meters, 4 meters and the like.
The brightness of the current lighting lamp bead 4 is increased or decreased according to the size of the distance value, and because the distance between the user and the lighting lamp bead 4 is in dynamic change, the display brightness of the lighting lamp bead 4 can be adjusted according to the size change of the distance value, namely step S4. For example, when the distance is small, that is, the distance between the user and the lighting bead 4 is very short, the compensation lamp 7 stops starting, and the number of partially lighted lighting beads 4 is reduced; when the distance is great, when the receiver is far away from the lighting lamp bead 4, the compensation lamp 7 is started, and the brightness of the lighting lamp bead 4 is enhanced.
When the ambient brightness value is greater than the threshold value, the user is not affected by the external ambient brightness within the projection range of the lighting bead 4 under the current ambient brightness, that is, step S5.
The brightness compensation method in the embodiment comprises the following steps: s1: acquiring a current environment brightness value; s2: judging whether the current brightness value is smaller than a threshold value; s3: if so, acquiring a distance value between the current receiver and the lighting lamp bead; s4: adjusting the brightness of the compensating lamp according to the distance value to compensate for the light attenuation of the illuminating lamp beads; s5: the current subject is not affected by illumination lamp pearly-lustre decay.
