Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic diagram of a sunlight reflecting lamp, 101 is the sun, 102 is a reflector, 103 is a rotating body, 104 is a base, 105 is a target area, 106 is a target area 1,107 is a target area n, the reflector 102 is arranged on the rotating body 103, and the rotating body 103 drives the reflector 102 to reflect sunlight to the target area. The reflector has certain scattering, so the target area has certain area range. The possible directions of the target area are uncertain, that is, the reflected light of the reflector lamp can not be seen in a certain area, theoretically, if the reflector is made into a sphere, the sunlight can be reflected to any direction, but the sphere is divergent reflected and not parallel light, so that strong light can not be generated, and flickering can not be generated, so that the invention researches that the reflecting angle is selected as much as possible, the covering irradiation of most target areas is realized through rotation, and the flickering effect is also realized, the reflecting angle is selected as much as possible, which means that the reflector is selected as much as possible, because the area of the reflector arranged on the rotating body is certain, the area of a single reflector is smaller and the reflecting intensity is smaller when the quantity of the reflectors is larger, the quantity of the reflectors is set according to specific application, for example, the area of the reflector is larger when the reflector is used for long-distance irradiation, and the optimized reflecting angle is set, the optimized reflection angle is obtained by calculating the solar angle of a certain geographic position (such as a perpetual calendar, which is a known technical method). Referring to fig. 2, a configuration diagram of a reflector and a vertical direction angle of a sunlight reflector lamp is shown, considering that the highest angle of the sun is vertical direct light, the lowest angle is horizontal direct light, and according to a reflection law, a reflection angle should be equal to an incident angle, so that the angle of the reflector to obtain most horizontal direction irradiation is 0-45 degrees theoretically, an included angle between a plane of the reflector and the vertical direction in fig. 2 is alpha, the alpha angle is 0-360 degrees theoretically, specific implementation can be divided into-90 degrees to +90 degrees, the reflector is suitable for horizontal direction irradiation when the alpha angle is 0-45 degrees, and the alpha angle is 45-90 degrees when aerial irradiation (such as application to an aerial navigation lamp) is considered. Referring to fig. 13, which is a top view of the rotating body in fig. 1, in addition to the reflective mirror 102, a plurality of reflective mirrors 1301, 1032, 1303, 1304, 1305, 1306 with different angles α are arranged on the side of the rotating body 103 along the tangential direction of the rotating body, and eight reflective mirrors with different angles are taken as an example in the drawing, and according to the formula α = n × 90/(m-1), n is the number of the reflective mirrors, and m is the total number of the reflective mirrors, the reflective mirrors can be set (as illustrated by m = 8): 102 angles =0 × 90/(8-1) =0 degrees, 1301 angles =1 × 90/(8-1) =12.86 degrees, 1302 angles =2 × 90/(8-1) =25.71 degrees, 1303 angles =3 × 90/(8-1) =38.57 degrees, 1304 angles =4 × 90/(8-1) =51.43 degrees, 1305 angles =5 × 90/(8-1) =64.29 degrees, 1306 angles =6 × 90/(8-1) =71.14 degrees, 1307 angles =7 × 90/(8-1) =90 degrees. Or only considering the illumination below the horizontal line, α = n × 45/(m-1) (degrees); if only in-air illumination is considered, α =45+ n × 45/(m-1) (degrees). The reflector angle is obtained according to the average value, and when the method is implemented, series of optimized angle data can be obtained according to the reflection requirement. The number of m does not limit the present invention.

Further, in consideration of the requirement of synchronous flicker, a compass or a direction sensor (magnetic element) is arranged on the base or the rotating body of the reflector lamp, and the compass or the direction sensor is used for determining the synchronous starting position, or the compass or the direction sensor is used for calibrating the initial position, i.e. the initial position, of the reflector lamp.

The psychological study shows that human eyes can attract subjective attention when the human eyes regard the synchronous flickering objects as a whole, and the indication attention can be formed subjectively when the human eyes regard the flowing water flickering objects.

The rotation speed of the rotator may be controlled within 24 rpm in consideration of the visual retention time of the human eye. In addition, the human eye feels the light intensity and the light time is accumulated in addition to the light intensity, so that the rotation is too fast, the maximum light intensity is averaged when the irradiation time is shorter than the human visual residual time, and therefore, in order to ensure that the maximum light intensity is not averaged and the daytime visibility is realized, the rotation speed of the rotating body is controlled within 24 revolutions per second.

Further, under general light intensity, the response of human eyes to time frequency is similar to a band-pass filter, the human eyes are most sensitive to signals of 15-20 Hz and have strong flickering sense (flick), the response is 0 when the response is larger than 75Hz, the flickering sense disappears, the frequency which just reaches the flickering sense disappearance is called Critical Fusion Frequency (CFF), the human eyes are in low-pass characteristic in a dark environment, the CFF is reduced, and at the moment, the human eyes are most sensitive to signals of 5Hz and flickering larger than 25Hz is basically disappeared. Accordingly, the flicker frequency is selected to be 5 to 20Hz, and the corresponding period is 0.04 to 0.2 seconds, so the rotating speed of the rotating body can be controlled to be 5 to 20 revolutions per second.

The solar altitude angle (solar vertical angle) refers to the angle between the light ray directly projected from the center of the sun to the local and the local horizontal plane, the solar direction angle refers to the angle between the projection of the solar ray on the ground plane and the local meridian, and can be approximately regarded as the angle between the shadow of a straight line standing on the ground in the sun and the true south, so the solar angle can be decomposed into a horizontal direction angle gamma and a vertical direction angle beta, wherein the solar direction angle gamma = FL (geographical position, time), FL is a horizontal movement function, the true south direction is uniformly selected as a reference on the assumption that the direction angle is, the solar vertical direction angle (altitude angle) beta = FH (geographical position, time), and FH is a vertical movement function and is relative to the horizontal line.

According to the law of reflection, the reflection of light on the reflector satisfies the reflection angle equal to the incident angle, from which the angle of reflection of the light reflected to the target zone can be calculated, expressed as:

target horizontal retroreflection angle γ r = FLr (reflector geographic position, target geographic position, time), FLr is a horizontal retroreflection movement function. Further converted into horizontal direction angle γ rs (relative to the normal south direction) = FLrs (reflector lamp geographical position, target geographical position, time) of the reflector (normal), which is a reflector horizontal reflection movement function.

Target vertical glistening angle β r = FHr (reflector geographical position, target geographical position, time), FHr is a vertical glistening movement function. Further converted into a vertical direction angle beta rs (relative to the horizontal line) = FHRs (reflector lamp geographic position, target geographic position, time) of the reflector (normal), wherein the FHRs is a reflector vertical reflecting movement function.

The reflector lamp geographical position and the target geographical position also include altitude information, taking into account the vertical altitude.

The function may be used to optimize the mirror angle calculation to achieve the desired effect on the angle and position of the reflected light.

The reflector angle is obtained according to the average value, and when the method is implemented, series of optimized angle data can be obtained according to the reflection requirement. The number of m does not limit the present invention.
