[0034] By setting the above-mentioned control device 6, when it is necessary to adjust the light angle of the LED lamp, it is only necessary to turn the control device 6 to control at least one group of LED lamp beads in the multiple groups of LED lamp beads at different positions of the LED lamp board 2 under the lens board 3 to emit light.
[0035] It also includes a sealing ring 7 arranged between the lens plate 3 and the LED light board 2 and a sealing ring 8 arranged between the driving power supply 4 and the radiator 1, which can achieve a good waterproof effect.
[0036] See also Figure 3 、 Figures 9 and 10 As shown, the plurality of groups of LED lamp beads are evenly arranged in a circular manner around the axis a of the plate 5. The radius of the circular ring close to the axis a of the plate 5 is the smallest, and then the radius of the circular ring increases from the axis a to the direction away from the axis. The plurality of groups of LED lamp beads include a first group of lamp beads 9 and a second group of lamp beads 10 (refer to Figure 9As shown, the red circle is a first group of lamp beads 9, and the outside of the circle is a second group of lamp beads 10). The first group of lamp beads 9 is arranged inside the plate body 5, and the second group of lamp beads 10 is arranged outside the plate body 5.
[0037] The control device 6 includes an angle controller 11, which consists of a switch base 12, a first electronic switch 13 and a first handle 14. The switch base 12 is fixed in a power box 15, and the first electronic switch 13 is fixedly mounted on the switch base 12. The two ends of the first electronic switch 13 are electrically connected to the driving power supply 4 and the LED light board 2 respectively. The first handle 14 is connected to the first electronic switch 13. The first handle 14 is used to be turned to change the state of the angle controller 11. The first electronic switch 13 is used to control the first group of lamp beads 9 to emit light and whether the second group of lamp beads 10 emit light according to different states.
[0038] When it is necessary to adjust the light output angle to the desired one, it is only necessary to toggle the first handle 14 of the angle controller 11 so that the first electronic switch 13 is in the corresponding state, as follows:
[0039] When the first electronic switch 13 is in the first state, the first group of lamp beads 9 and the second group of lamp beads 10 all emit light;
[0040] When the first electronic switch 13 is in the second state, the first group of lamp beads 9 emits light, and the second group of lamp beads 10 does not emit light.
[0041] The first group of lamp beads 9 and the second group of lamp beads 10 both include first lamp beads 16 and second lamp beads 17 . The first lamp beads 16 and the second lamp beads 17 are alternately arranged on the plate 5 in a circular arrangement.
[0042] See also Figures 2 to 4 As shown, the control device 6 also includes a color temperature controller 18, which includes the switch base 12, a second electronic switch 19, and a second handle 20.

The second handle 20 is connected to the second electronic switch 19. The second handle 20 is used to be toggled to change the state of the color temperature controller 18. The second electronic switch 19 is used to control the first lamp bead 16 and the second lamp bead 17 to emit light according to different states. The color temperature value of the first lamp bead 16 is 2700K, and the color temperature value of the second lamp bead 17 is 5000K.
[0043] When the color temperature value is to be adjusted to the desired value, it is only necessary to toggle the second handle 20 of the color temperature controller 18 so that the second electronic switch 19 is in the corresponding state, as follows:
[0044] When the second electronic switch 19 is in the first state, the first lamp bead 16 and the second lamp bead 17 are fully illuminated, and the color temperature thereof is 4000K;
[0045] When the second electronic switch 19 is in the second state, the two lamp beads 17 emit light, and the color temperature thereof is 5000K.
[0046] See also Figure 1 、 Figure 3 、 Figures 7 and 8 As shown, the lens plate 3 is placed on multiple groups of LED lamp beads, which includes a lens frame 21 and multiple raised lenses arranged on the lens frame 21.

[0047] The plurality of protruding lenses include a first lens group 23 and a second lens group 24 (refer to Figure 7 , the inner part circled in red is the first group of lenses 23, and the outer part is the second group of lenses 24). The first group of lenses 23 includes a plurality of raised annular strip-shaped first lens portions 25 and is evenly arranged in an annular manner inside the lens plate 3 around the axis b of the lens frame 21 on the lens frame 21. The radius of the annular ring close to the axis b of the lens frame 21 is the smallest, and then the radius of the annular ring increases successively; the through hole 22 corresponding to the first lens portion 25 is annular strip-shaped.
[0048] The second group of lenses 24 includes a plurality of convex arc-shaped second lens portions 26. The second lens portions 26 are evenly arranged in a circular manner on the outside of the lens frame 21 around the axis b of the lens frame 21.

The radius of the circular ring close to the axis b of the lens frame 21 is the smallest, and the radius of the circular ring then increases in sequence. The second lens group 24 includes a plurality of raised arc-shaped second lens portions 26. The plurality of second lens portions 26 are evenly arranged in a circular manner outside the lens frame 21. Because the focal length of the convex lens affects the light output angle after passing through the convex lens, the above arrangement can enable the LED lamp to have different light output angles.
[0050] When the first electronic switch 13 is in the first state, that is, the first group of lamp beads 9 and the second group of lamp beads 10 are all emitting light, the light emitted by the first group of lamp beads 9 passes through the light incident surfaces of the multiple first lens portions 25 of the first group of lenses 23, is then concentrated and emitted to the outside world; the light emitted by the second group of lamp beads 10 passes through the light incident surfaces of the multiple second lens portions 26 of the second group of lenses 24, is then collected and emitted to the outside world, and the refracted light angle is 60°;
[0051] When the first electronic switch 13 is in the second state, that is, the first group of lamp beads 9 emits light and the second group of lamp beads 10 does not emit light, the light emitted by the first group of lamp beads 9 passes through the light incident surfaces of the multiple first lens portions 25 of the first group of lenses 23, and is then concentrated and emitted to the outside world. The refracted light angle is 90°.
[0052] The control device 6 also includes a power controller 27 for adjusting the power of the LED lamp, including the switch base 12, a third electronic switch 28 and a third handle 29.

The third handle 29 is connected to the third electronic switch 28. The third handle 29 is used to be toggled to change the state of the power controller 27. The third electronic switch 28 is used to control the power of the LED lamp according to different states.
[0053] When selecting the above lighting angles, the power controller 27 or color temperature controller 18 of the LED lamp can also be adjusted to the desired power or color temperature. The first, second, and third handles 14, 20, and 29 can be extended outside the power box 15 to facilitate adjustment. A plug 30 is also included to block the control device 6, achieving a good waterproof and dustproof effect.
[0054] The control device 6, the driving power supply 4 and the power supply box 15 are glue-filled and integrated.
[0055] It also includes a hanging ring 31 installed on the power box 15 of the driving power supply 4 for installing the LED lamp, so that the LED lamp can be installed on the ceiling.
[0056] The present invention does not require replacement of the lens 3. The light angle of the lamp can be adjusted by simply toggling the angle controller 11 to switch the LED lamp beads at different positions on the LED lamp board 2. It also includes a color temperature controller 18 and a power controller 27. Users can adjust the corresponding color temperature or power according to their needs, saving the cost of replacing the lens and being safer and more reliable.
