[0033] In the specific technical features and embodiments described in the specific embodiments, any suitable combination can be combined without contradiction, for example, different specific technical features / embodiments can form different embodiments. In order to avoid unnecessary repetition, various possible combinations of various specific technical features / embodiments in the present application are not described again.

[0034] As shown in Figures 1 to 5 The floodlight provided by the embodiment of the present application includes at least two lamp heads 12. The floodlight further includes a mounting bracket 345, each of the lamp heads 12 is connected to the mounting bracket 345 and can rotate relative to the mounting bracket 345. The floodlight further includes a wireless module 6, a control module 7 and an adjusting module. The control module 7 is connected to the wireless module 6 and the adjusting module respectively, and the adjusting module is connected to the lamp head. The wireless module 6 is arranged on the mounting bracket 345 and is used to measure the distance between the wireless module 6 and the adjacent floodlight to obtain the measured distance S' (as shown in Figure 5 The control module 7 outputs the required rotation angle of each lamp head according to the measured distance S'. It is necessary to explain that the distance S' can be converted into the distance S between the adjacent lamp heads in the two floodlights (the distance between the lamp head and the wireless module for distance measurement is a constant value). As an optional embodiment, the control module can include a control mainboard, and the effective illumination angles a and β are fixed parameters of the lamp head, wherein a is the included angle between the optical axis of one of the lamp heads and the maximum illumination boundary, and β is the included angle between the optical axis of the other lamp head (the lamp head adjacent to one of the lamp heads in the other floodlight) and the maximum illumination boundary. In the present embodiment, a and β are the same, and the area to be illuminated on the ground is the same as the illumination area of the adjacent lamp heads in the two floodlights. Since the distance h between the lamp head and the illuminated ground is constant (as shown in Figure 5The height of the two lamp heads is generally 2 to 4 meters, and the default height in the embodiment is 3 meters. The height difference of the two lamp heads can be ignored, or h can also be measured by the wireless module (the wireless module 6 also includes a height ranging component for measuring the distance between the lamp head and the ground, and can also include a horizontal ranging component for measuring the distance between the two adjacent lamp heads). According to the trigonometric function relationship, the illumination range size S1 and S2 of the two adjacent lamp heads can be obtained (S1 is the distance between the intersection of the optical axis of one of the lamp heads and the illumination surface and the intersection of the maximum illumination boundary and the illumination surface; S2 is the distance between the intersection of the optical axis of the other lamp head and the illumination surface and the intersection of the maximum illumination boundary and the illumination surface). The control module 7 sets the calculation program according to the algorithm S1+S2≥S and outputs the required rotation angle of each of the two adjacent lamp heads, so as to ensure that there is no dark area in the illumination range. In another embodiment, as shown in Figure 7 The two adjacent floodlights are used to jointly illuminate the illumination area S. The wireless module 6 is directed to the set illumination point (since the effective illumination angle of the lamp head 12 is fixed, that is, the effective illumination area is unchanged, each floodlight only needs to cover half of the illumination area, and the effective illumination area of each floodlight covers half of the illumination area, that is, the light of each lamp head 12 covers an illumination area of S0 (that is, S / 4), and the rotation angle θ is arctan(S / 4h). This can prevent dark areas from being generated due to improper angle adjustment. The rotation angle of each lamp head 12 is adjusted to maximize the effective use of light and eliminate dark spots. The adjustment module adjusts the rotation of each lamp head according to the required rotation angle, so that the light fills the space to be illuminated, maximally reduces or eliminates dark areas, and realizes joint floodlighting and improves the effective use of light. One floodlight includes a mounting bracket, a control module, an adjustment module, and two lamp heads. The structure is simple and convenient to install. Only by connecting the terminal such as a mobile phone to the control module 7, the angle of the lamp can be adjusted by the terminal, or a controller can be set. The controller is connected to the control module 7, and the controller can also be conveniently adjusted.

[0035] In some embodiments, the mounting bracket 345 comprises a fixed bracket 3, a first bracket 4 and a second bracket 5, the first bracket 4 and the second bracket 5 are respectively rotatably connected to two ends of the fixed bracket 3, one end of each of the lamp heads is connected to the first bracket 4, and the other end of each of the lamp heads is connected to the second bracket 5; the adjusting module comprises a main adjusting module 8 for adjusting the rotation of the first bracket 4 and the second bracket 5 relative to the fixed bracket 3. In a specific application, when the installation plane is uneven, the fixed bracket 3, the first bracket 4 and the second bracket 5 are adjusted to set an angle of rotation, and then each of the lamp heads is rotated relative to the fixed bracket 3, so that each of the lamp heads remains in the same horizontal plane (parallel to the ground) before the rotation adjustment angle. Specifically, the distance between each lamp head and the ground in the same floodlight can be measured by a range finder. The range finder can be arranged on the lamp head, and the number of range finders is the same as the number of lamp heads. The range finder is a laser range finder for measuring the vertical distance between each lamp head and the ground. More specifically, the shortest distance, i.e. the vertical distance between the light emitting surface of each lamp head and the ground, is measured by the laser range finder. (It should be noted that during the adjustment process, the light emitting surfaces of each lamp head are located in the same plane.) When the distance is the same, it indicates that each lamp head is parallel to the ground, i.e. the light emitting surface of each lamp head is parallel to the ground, thereby realizing the correction of each lamp head in the same floodlight relative to the horizontal direction. In another embodiment, the main adjusting module 8 can be adjusted to adjust each of the lamp heads as a whole, for example, after adjusting each of the lamp heads to face a certain side, each of the lamp heads is adjusted to rotate an angle, for example, two lamp heads need to be rotated by 45 degrees, and the first bracket and the second bracket are only rotated by 45 degrees to adjust the two lamp heads to 45 degrees at the same time. Or the first lamp head needs to be rotated by 45 degrees, and the second lamp head needs to be rotated by 30 degrees. First, the first bracket and the second bracket are rotated by 30 degrees, and then the first adjusting module is adjusted to rotate the first lamp head by 15 degrees. This can reduce the adjustment range and realize the fastest speed to adjust each lamp head to the required rotation angle, and the adjustment is more convenient and fast.

In a specific application, the first adjusting module 9 adjusts the relative rotation of the first lamp head 1 relative to the first left connecting rod 41 and the second left connecting rod 51, and the second adjusting module 10 adjusts the relative rotation of the second lamp head 2 relative to the first right connecting rod 42 and the second right connecting rod 52, thereby realizing independent adjustment of the first lamp head 1 and the second lamp head 2, so that the first lamp head 1 and the second lamp head 2 can be as full as possible for the space to be irradiated, and dark areas are minimized or eliminated, each floodlight has a corresponding effective illumination area in the area to be irradiated, and by adjusting the first lamp head 1 and the second lamp head 2, the effective illumination area boundary of adjacent floodlights is partially overlapped, and in the area to be irradiated, the dark area caused by improper angle adjustment of adjacent floodlights is eliminated, and joint floodlighting is realized.

[0038] In some embodiments, the fixed support 3 comprises a transverse support 31 and a longitudinal support 32, one end of the longitudinal support 32 is connected to both ends of the transverse support 31, and the fixed support 3 can be in the shape of “|”. The control module 7 is arranged in the transverse support 31, and the wireless module 6 and the main adjustment module 8 are arranged in one of the longitudinal supports 32; the first support 4 is connected to the other end of one of the longitudinal supports 32, and the second support 5 is connected to the other end of the other longitudinal support 32. In this embodiment, the wireless module 6 can be a radio ranging module (based on electromagnetic wave application technology ranging, such as laser ranging), or the wireless module 6 can also use Wifi ToF double-sided two-way ranging to realize accurate ToF measurement between two WiFi devices, which is accurate and efficient, and is conducive to the control module 7 outputting more accurate rotation angle, and further conducive to the elimination of dark areas.

As an optional embodiment, the adjustment module adopts a gear adjustment mechanism, which can realize relatively fine angle adjustment, and in other embodiments, the adjustment module can adopt a worm gear transmission mechanism, which can also realize accurate rotation angle adjustment.

[0042] In some embodiments, the first adjusting module 9 is a first gear adjusting mechanism, which comprises a first driving member, a first driving wheel and a first transmission wheel; the first driving member is connected to the control module 7, the first driving wheel is connected to the first driving member, and the first transmission wheel is in transmission connection with the first driving wheel; the first transmission wheel is fixedly connected with a first connecting shaft for driving the first lamp head 1 to rotate relative to the first support 4 and the second support 5, and the first connecting shaft is connected with the first lamp head 1; the second adjusting module 10 is a second gear adjusting mechanism, which comprises a second driving member, a second driving wheel and a second transmission wheel; the second driving member is connected to the control module 7, the second driving wheel is connected to the second driving member, and the second transmission wheel is in transmission connection with the second driving wheel; the second transmission wheel is fixedly connected with a second connecting shaft for driving the second lamp head 2 to rotate relative to the first support 4 and the second support 5, and the second connecting shaft is connected with the second lamp head 2. Specifically, a gasket is further arranged between the main connecting shaft and the second support 5, between the first connecting shaft and the first left connecting rod 41, and between the second connecting shaft and the first right connecting rod 42; the friction force between the gasket and each connecting shaft is a pre-tightening force, which can keep the angle stable after rotation, accurately and reliably adjust the angle, and integrally connect each connecting shaft with the mounting support 345 or make the shaft hole of the mounting support 345 for mounting the connecting shaft non-circular, so as to not only ensure that each connecting shaft and the mounting support 345 rotate synchronously under the driving of the driving motor, but also facilitate assembly and disassembly, which is more convenient; in the embodiment, the main driving member 81, the first driving member and the second driving member are all step motors, and the gear set has a multi-stage transmission gear combination, i.e. the transmission gear is provided with a plurality of gears, which can proportionally reduce the speed of the step motor, so as to realize more accurate angle adjustment.

[0043] As shown in Figure 8 The application also provides a combined control method of the floodlight, which is used for controlling the floodlight and comprises the following steps: a measuring step, an outputting step and an adjusting step.

[0044] In the measuring step, the wireless module 6 measures (acquires) the distance between the floodlight and the adjacent floodlight to obtain a measured distance S'; in specific applications, the wireless module 6 further comprises a height distance measuring component for measuring the distance between the lamp head and the ground, and can also comprise a horizontal distance measuring component for measuring the distance (the distance S in the embodiment) between the two adjacent lamp heads, which can be arranged on the lamp head to make the measurement more accurate.

[0045] In the outputting step, the control module 7 outputs the rotation angle of the floodlight according to the measured distance S'; specifically, as shown in Figure 5As shown, the effective illumination angles α and β are fixed parameters of the lamp head, where α is the angle between the optical axis of one lamp head and the maximum illumination boundary, and β is the angle between the optical axis of the other lamp head and the maximum illumination boundary. Since the distance h between the lamp head and the illuminated ground is constant (e.g., ... Figure 5 As shown), based on trigonometric relationships, the illumination area dimensions S1 and S2 of two adjacent lamp heads can be obtained (where S1 is the distance between the intersection of the optical axis of one lamp head and the illumination surface, and the intersection of the maximum illumination boundary and the illumination surface; S2 is the distance between the intersection of the optical axis of the other lamp head and the illumination surface, and the intersection of the maximum illumination boundary and the illumination surface). The control module 7 of the main board sets the calculation program according to the trigonometric relationships and the algorithm S1+S2≥S and outputs the required rotation angle of each of the two adjacent lamp heads; in another embodiment (such as... Figure 7 As shown), two adjacent floodlights are used to jointly illuminate the illumination area S. The light from each lamp head 12 covers the illumination area S0 (i.e., S / 4), and the rotation angle θ is arctan(S / 4h), which can be used to output the rotation angle θ.

[0046] The adjustment step involves the adjustment module adjusting the rotation of each of the lamp heads 12. As an optional embodiment, the lamp angle can be adjusted by wirelessly connecting to the control module 7 via a mobile phone or other terminal, or a controller can be set up and connected to the control module 7 to trigger and control the adjustment.

[0047] In specific applications, the adjustment steps include a main adjustment step, a first adjustment step, and a second adjustment step. The main adjustment step includes the main adjustment module 8 controlling the first bracket 4 and the second bracket 5 to rotate relative to the fixed bracket 3 by a set angle to horizontally correct each of the lamp heads 12, that is, adjusting each of the lamp heads 12 to be parallel to the ground (specifically, the distance between each lamp head and the ground can be measured by a rangefinder; when the distances are the same, it indicates that each lamp head is parallel to the ground). The first adjustment step includes adjusting the first lamp head 1 to rotate relative to the first bracket 4 and the second bracket 5 by a set angle (that is, according to the rotation angle of each lamp head output by the control module 7). The second adjustment step includes adjusting the second lamp head 2 to rotate relative to the first bracket 4 and the second bracket 5 by a set angle (that is, according to the rotation angle of each lamp head output by the control module 7). The adjustment is quick and convenient. The control module 7 controls the motor to be powered on, which can control the rotation of the lamp head. After the set angle is reached, the motor is powered off. The rotating shaft of the lamp head can be equipped with a pre-tightening component (specifically, the first connecting shaft is equipped with a first pre-tightening component, and the second connecting shaft is equipped with a second pre-tightening component) so that the lamp head 12 maintains a stable angle after rotation.
