The dovetail groove 3 is arranged at the root of the screw thread 2 and the O-ring 26 is sleeved on the dovetail groove 3. The edge of the waterproof front cover 4 adjacent to the O-ring 26 and the edge of the waterproof rear cover 5 adjacent to the O-ring 26 are the beveled edge 27, respectively. The waterproof front cover 4 is threaded with the front end of the main body 1, and the waterproof rear cover 5 is threaded with the rear end of the main body 1. The waterproof front cover 4 and the waterproof rear cover 5 are bowl-shaped.
The principle and advantages of the above technical solution are as follows. The waterproof front cover 4 and the waterproof rear cover 5 are respectively installed on the front end and the rear end of the main body 1 by means of the screw thread 2. During the screwing process, the waterproof rear cover 5 causes the O-ring 26 to squeeze inward along the dovetail groove 3 of the main body 1, to form a water-tight seal at the rear end. Since the edge of one end of the waterproof front cover 4 is the beveled edge 27, during the screwing process, the waterproof front cover 4 causes the O-ring to squeeze inward along the dovetail groove 3 of the main body 1 to achieve a waterproof seal at the front end.
In an embodiment, the main body 1 is provided with the inner cavity, and the bulkhead 6 is arranged in the inner cavity. The bulkhead 6 divides the inner cavity into the front cavity 7 and the rear cavity 8. The spotlight adjusting component is arranged in the front cavity 7, and the color temperature adjusting component is arranged in the rear cavity 8.
The spotlight adjusting component includes:
the light source bracket 9, wherein the light source bracket 9 is fixed to the bottom wall of the front cavity 7 by the screw, the light source bracket 9 presses the luminous body against the bottom wall of the front cavity 7, three lug bosses 29 are arranged on the light source bracket 9 in the circumferential direction;
the lens holder 10, wherein, three oblique grooves 30 are arranged on the outer wall of the lens holder 10 in the circumferential direction; the lug boss 29 is engaged into the oblique groove 30; the lens 11 is installed on the lens holder 10; the honeycomb net 28 and the color filter 12 are placed on the top of the lens 11 in sequence; the lens holder is provided with the upwardly tilted waist-shaped sliding grooves; the convex rib is arranged in the sliding groove to increase the damping during rotation, making the operation better; and
the rotating cylinder 13, wherein the rotating cylinder 13 is engaged into the lens holder 10.
The color temperature adjusting component includes:
the plastic power supply box 14, wherein, the plastic power supply box 14 is fixed on the inner wall of the rear cavity 8 by the screwing; one end of the plastic power supply box 14 is provided with the intelligent control power supply 15, and two electronic leads of the luminous body are connected to the output terminal of the intelligent control power supply 15;
the square groove 16, wherein the square groove 16 is arranged on the side wall of the main body 1; the waist-shaped hole 17 and the threaded hole 18 are arranged on the bottom of the square groove 16; the adapter block 19 is arranged in the square groove 16; the adapter block 19 is fixed in the square groove 16 by the bolt; and
the rotating arm 20, wherein, one end of the rotating arm 20 is engaged with the adapter block 19, the other end of the rotating arm 20 is provided with the screw thread, and the rotating arm 20 can be fixedly connected to the fixed base by the screw thread; the input lead of the intelligent control power supply 15 passes out of the side wall of the main body 1, successively through the adapter block 19 and the rotating arm 20, and is then connected to the wire 21; as shown in
The principle and advantages of the above technical solution are as follows. When the size of the spotlight needs to be adjusted, the waterproof front cover 4 is unscrewed, the rotating cylinder 13 is manually rotated to turn the lens holder 10 and the lens 11. The lug boss 29 moves along the oblique groove 30, so that the rotating cylinder 13 rotates clockwise and the lens 11 moves away from the luminous body, thereby decreasing the size of the spotlight; when the rotating cylinder 13 rotates counterclockwise, the lens 11 moves closer to the luminous body, thereby increasing the size of the spotlight. After the adjustment of the spotlight, the waterproof front cover 4 is screwed so that the O-ring is pressed into the dovetail groove of the main body 1 to achieve sealing, thereby preventing water from entering the cavity. During rotation, the convex rib on the lug boss 29 and the convex rib on the oblique groove 30 create a damping effect on each other, making the angle adjustment tactile. When the brightness and the color temperature need to be adjusted, the waterproof rear cover 5 is unscrewed, the dimming button 22 is rotated to adjust the brightness, and the color temperature adjusting button 23 is rotated to adjust the color temperature. After adjustment, the waterproof rear cover 5 is screwed so that the O-ring is pressed into the dovetail groove of the main body 1 to form a waterproof seal preventing water from entering the cavity. The rotating cylinder, the dimming button and the color temperature adjusting button, when not adjusted, are sealed by the waterproof front cover and the waterproof rear cover. Therefore, it is not easy to contact with water to cause failure, thereby improving the service life of the spotlight.
In an embodiment, as shown in

the guide rod 38, wherein the guide rod 38 is arranged under the sliding groove 35; one end of the guide rod 38 is connected to the side wall of the first bevel gear 34, and the other end of the guide rod 38 passes through the annular opening 37 and extends out of the housing 32;
the cleaning ring 39, wherein the cleaning ring 39 is sleeved on the outer wall of the main body 1; the side wall of the cleaning ring 39 is provided with the second through hole 40 extending in the axial direction; the end of the guide rod 38 away from the first bevel gear 34 passes through the second through hole 40 and is connected to the stop block 41; the bristle is arranged on the inner wall of the cleaning ring 39;
the spring 42, wherein the spring 42 is sleeved on the guide rod 38; one end of the spring 42 is connected to the side wall of the first bevel gear 34, and the other end of the spring 42 is connected to the cleaning ring 39; and
the connecting rod 43, wherein one end of the connecting rod 43 is hinged to the sliding block 36, and the other end of the connecting rod 43 is hinged to the outer wall of the cleaning ring 39.
The cleaning device further includes the motor 46, wherein the motor 46 is arranged on the outer wall of the main body 1. The motor 46 is located in the housing 32, and the output shaft of the motor 46 extends outwards and is connected to the second bevel gear 47. The first bevel gear 34 is engaged with the second bevel gear 47.
The principle and advantage of the above technical solution are as follows. When the outer wall of the spotlight needs to be cleaned, the motor 46 is activated to drive the second bevel gear 47 to rotate. Since the second bevel gear 47 is engaged with the first bevel gear 34, the second bevel gear 47 drives the first bevel gear 34 to rotate, and the sliding block 36 moves toward the outside of the sliding groove 35 under the action of the centrifugal force. Therefore, the connecting rod 43 drives the cleaning ring 39 to move left along the guide rod 38, and compress the spring 42. The centrifugal force is changed by the rotating speed of the motor 46, and thus the balance position of the cleaning ring 39 changes, and the cleaning ring 39 moves back and forth, right and left. Meanwhile, the cleaning ring 39 keeps rotating, so that the bristle on the inner wall of the cleaning ring 39 cleans the outer wall of the main body 1, removing dust from the outer wall of the main body 1.
