[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1-4As shown, this embodiment provides a dual-color temperature LED module with adjustable emission angle, including a lampshade 1 and a light source module 3. A lens 2 is mounted above the light source module 3 below the lampshade 1. The lens 2 is a truncated cone component. An inner LED ring 10 is disposed below the lens 2 on the upper surface of the light source module 3. An outer LED ring 9 is disposed outside the inner LED ring 10 on the upper surface of the light source module 3. A first controller 4 is disposed to the upper left of the outer LED ring 9. A second controller 5 is mounted to the right of the first controller 4 on the upper surface of the light source module 3. A third controller 6 is mounted below the first controller 4 on the upper surface of the light source module 3. A fourth controller 7 is mounted below the second controller 5 on the upper surface of the light source module 3. The first controller 4 and the second controller 5 are electrically connected to the inner LED ring 10. The third controller 6 and the fourth controller 7 are both electrically connected to the outer LED ring 9. High and low color temperature LED beads are alternately arranged inside the outer LED ring 9 and the inner LED ring 10. The first controller 4 is used to control the low color temperature LED beads inside the inner LED ring 10, the second controller 5 is used to control the high color temperature LED beads inside the inner LED ring 10, the third controller 6 is used to control the low color temperature LED beads inside the outer LED ring 9, and the fourth controller 7 is used to control the high color temperature LED beads inside the outer LED ring 9. A mounting slot 8 is opened on one side of the light source module 3. A mounting block 101 is installed on the inner side wall of the lamp cover 1 at the position corresponding to the mounting slot 8. The mounting block 101 is engaged with the mounting slot 8. A positioning rod 102 is provided inside the mounting block 101. An elastic rotating shaft is installed between the positioning rod 102 and the mounting block 101.
[0020] The working principle of this utility model is as follows: The brightness of the LEDs in the outer LED ring 9 and the inner LED ring 10 is controlled by a first controller 4, a second controller 5, a third controller 6, and a fourth controller 7. When the overall brightness of the LEDs inside the inner LED ring 10 is at its maximum, the brightness of the outer LED ring 9 is controlled to its minimum. The LEDs inside the inner LED ring 10 are concentrated and have a small luminous surface. Through the secondary optics of the lens 2, a beam angle of 10° is achieved. When the overall brightness of the LEDs inside the inner LED ring 10 is at its minimum, the brightness of the outer LED ring 9 is controlled to its maximum. The luminous area of the LEDs inside the outer LED ring 9 is large. Through the secondary optics of the lens 2, a beam angle of 36° is achieved. (The beam angle is a set value and can be adjusted according to the arrangement of the LEDs and the secondary optics of the lens.) The required angle is designed, and the brightness adjustment ratio can be set. Different brightness ratios correspond to different light emission angles and color temperature values, thus controlling different beam angles. Therefore, the light emission levels inside the outer LED ring 9 and the inner LED ring 10 can be changed to adjust the beam angle. With the different changes in brightness between the inner and outer rings, multiple light emission angles can be presented, thus achieving the function of variable angle. The first controller 4 is used to control the low color temperature LED beads inside the inner LED ring 10, the second controller 5 is used to control the high color temperature LED beads inside the inner LED ring 10, the third controller 6 is used to control the low color temperature LED beads inside the outer LED ring 9, and the fourth controller 7 is used to control the high color temperature LED beads inside the outer LED ring 9, adjusting and allocating different brightness ratios to the coarser setting of the LED beads inside the outer LED ring 9 and the inner LED ring 10 to change the color temperature.
