DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0029] Please refer to Figures 1-7 , the present application provides a technical solution:

[0030] Embodiment 1: Regarding the light angle adjustment of the down lamp, the light coverage range and the light intensity adjustment are usually achieved by adjusting the distance between the reflector cup and the lamp panel. This kind of down lamp adjustment is the most common, and for the down lamp installed in place, the projection light deflection adjustment is further performed without adjusting the whole lamp shell 1. As shown in Figure 1 , the angle adjustment of the lamp panel assembly 18 in the lamp shell 1 is completed to realize the flexible projection lighting.

[0031] The drive assembly two 13 and the drive assembly three 14 are installed on the inner wall of the lamp shell 1. The drive assembly two 13 and the drive assembly three 14 are fixed with the rotation control rod 15 at the end. The rotation control rod 15 is rotated by the micro motor in the drive assembly. The sleeve rod one 16 and the sleeve rod two 17 are movably connected at the end of the two sides of the rotation control rod 15. The deflection column 10 is movably connected at the end of the sleeve rod one 16 and the sleeve rod two 17. The deflection column 10 is located in the center of the lamp shell 1. As shown in Figure 3 , the pinion sleeve 6 movably connected in the middle of the lamp shell 1 is connected with the deflection column 10 in the middle. The deflection column 10 is connected with the lamp panel assembly 18 on the other side. With the swing of one end of the deflection column 10, the other end drives the lamp panel assembly 18 to move, and the light side angle adjustment of the lamp panel is completed.

[0032] As shown in Figure 4As shown, when the bottom light needs to be deflected to the right, the light is controlled by the law of reflection. The reflector cup 3 is concave. Whichever side it is deflected to, the top deflection rod moves to that side. The second drive component 13 is indirectly connected to the first sleeve rod 16, and the third drive component 14 is indirectly connected to the second sleeve rod 17. To move the top of the deflection rod to the right, the third drive component 14 drives the second sleeve rod 17 to rotate clockwise, while the second drive component 13 drives the first sleeve rod 16 to rotate counterclockwise. The clockwise rotating sleeve rod 17 has a certain amount of movement margin and generates a downward pulling force on the deflection rod when it rotates a certain angle. In the early stage of the movement, the second sleeve rod 17 pushes to the right. The angle between the passively rotating sleeve rod 17 and the control rod 15 increases, giving the deflection rod a downward pushing force, which makes it impossible to move to the right. Therefore, the second drive component 13 drives the control rod 15 to rotate counterclockwise to correct the entire path of the second sleeve rod 17 pushing the deflection rod.

[0033] As the top of the deflection rod moves to the right, its bottom moves in the opposite direction. The lamp panel assembly 18 connected to the end of the entire deflection rod shines towards the left side of the reflector cup 3. Through reflection by the reflector cup 3, the overall light deflects to the right, thus completing the adjustment of the overall downlight's light output angle.

[0034] When installing or adjusting downlights, the illumination range or direction can be changed by adjusting the angle between the lamp panel and the reflector. This adjustment method is often used to adjust the lighting area, avoid glare, or achieve specific lighting effects. To improve the overall accuracy of downlight control and environmental adaptability, its own light adjustment also has levels. When the distance between the installed downlight and the actual lighting area is small, precise light control can be achieved, such as... Figure 5 As shown, a positioning plate 7 is slidably connected to the inner wall of the central helical sleeve 6, and a ball bushing 8 is installed on the positioning plate 7;

[0035] The ball bushing 8 consists of a tubular sleeve and a ball sleeve. The ball sleeve is embedded inside the tubular sleeve and rolls in connection with it. The entire deflecting column 10 passes through the ball sleeve portion of the ball bushing 8. The ball sleeve positions the center of motion of the deflecting column 10, similar to the force center of a seesaw. By changing the position of the entire ball bushing 8 on the deflecting column 10, such as... Figure 7 As shown, when the entire ball bearing sleeve 8 moves downward, the range of motion of the upper half increases, and it swings and adjusts significantly, while the lamp panel assembly 18 on the deflection column 10 in the lower half only undergoes a small positional change. Conversely, when the entire ball bearing sleeve 8 moves upward, the upper half deflection sleeve moves, and the lamp panel assembly 18 undergoes a large positional change. This is suitable for installation in situations where the spacing difference is large and the light adjustment accuracy is not high.

[0036] To adjust the position of the ball bushing 8, an adjusting bolt 9 is installed on the positioning plate 7. Before the downlight is installed on the wall, the operator manually rotates the adjusting bolt 9. The rotating adjusting bolt 9 controls the entire positioning plate 7 to slide on the inner wall of the toothed sleeve 6, thereby adjusting the center position of the deflection column 10.

[0037] Example 2: For adjusting the deflection angle of the lamp panel assembly 18, the downlight can also adjust the corresponding reflector cup 3, such as... Figure 6 As shown, positioning grooves 4 are evenly provided on the outer wall of the reflector cup cover 3, and a spiral tooth sleeve 6 is movably connected between the reflector cup cover 3 and the lamp housing 1. The top of the spiral tooth sleeve 6 is provided with annular teeth, and a drive assembly 12 is provided on the inner wall of the lamp housing. The micro motor on the drive assembly 12 drives the entire spiral tooth sleeve 6 to rotate. During the rotation, the protrusions on its surface engage with the positioning grooves 4 on the reflector cup cover 3.

[0038] like Figure 5 As shown, the telescopic lever 5 connected to the top of the reflector cup 3 is fixed to the lamp housing 1, thus locking the position of the reflector cup 3. As the rotary sleeve 6 rotates, the protrusion on the rotary sleeve 6 presses the reflector cup 3 on the telescopic lever 5, causing the reflector cup 3 to move up and down inside the lamp housing 1. With the adjustment of the position of the reflector cup 3, the downlight can achieve a wider range of light position adjustments.

[0039] The entire downlight is fitted with a heat dissipation fin sleeve 11. A face ring is installed on the lamp housing 1 on the side of the reflector cup 3, and a light-transmitting plate is provided on the side of the face ring. The overall position adjustment of the reflector cup 3 and the lamp panel assembly 18 is limited. A spring clip 2 is installed on the lamp housing 1 to facilitate the subsequent overall installation of the downlight.

[0040] Projection direction adjustment principle: After receiving the angle deflection command, the system controller drives two micro motors to rotate, which in turn drives the control rods 15 at their ends to rotate. The two control rods 15 drive the sleeve rod 16 and sleeve rod 17 that are movably connected to them, respectively. The other ends of the two sleeve rods slide together on the ball end of the top of the deflection column 10. Through the joint movement of the two drive components, the top of the deflection column 10 can be pushed and pulled in three-dimensional space, so that it can produce multi-dimensional tilt. The bottom of the deflection column 10 is fixed to the lamp panel assembly 18. The tilt of its top will drive the lamp panel at the bottom to deflect in the opposite direction. According to the law of reflection of light, after the light emitted by the lamp panel hits the reflector cup 3, the direction of the reflected light will change, and finally the precise adjustment of the light output angle is achieved.

[0041] Light coverage and brightness adjustment principle: The micro motor of the drive component 12 starts and drives the rotary sleeve 6 to rotate. The protrusion on the inner wall of the rotary sleeve 6 engages with the positioning groove 4 on the outer wall of the reflector cup 3. At the same time, the telescopic rod 5 on the top of the reflector cup 3 is fixed to the lamp housing 1, which restricts the reflector cup 3 to move up and down but not rotate. Therefore, when the rotary sleeve 6 rotates, the protrusion on its inner wall will move along the positioning groove 4, thereby pushing the entire reflector cup 3 to move up and down inside the lamp housing 1. The relative distance between the reflector cup 3 and the lower lamp panel component 18 changes. According to the optical principle, this directly changes the degree of light convergence, thereby realizing the continuous adjustment of the projection light coverage and center illuminance.

[0042] The principle of adjusting sensitivity and amplitude levels: By manually rotating the adjusting bolt 9, the positioning plate 7 can be driven to move up and down on the inner wall of the toothed sleeve 6. The ball bearing sleeve 8 in the middle of the positioning plate 7 slides on the deflection column 10, which acts as the fulcrum of the deflection column 10 when it tilts. When the ball bearing sleeve 8 moves downward, the range of motion of the top of the deflection column 10 increases, while the range of motion of the bottom decreases. This is suitable for applications with low installation height and requiring fine adjustment. When the ball bearing sleeve 8 moves upward, the range of motion of the top of the deflection column 10 decreases, while the range of motion of the bottom light plate increases. This is suitable for applications with high installation height and requiring a wide range of adjustment.
