[0030] Reference Figures 1 to 10 The embodiment of the utility model shown is: an LED lamp, including a radiator 1, an LED light board 2, a lens plate 3 and a driving power supply 4, the driving power supply 4 is used to drive the LED light board 2, the front of the radiator 1 is provided with a mounting groove 5, the mounting groove 5 includes an enclosed groove wall 6, the LED light board 2 is installed on the groove bottom of the mounting groove 5; the lens plate 3 covers the LED light board 2 and is movably connected to the groove wall 6, and also includes a pressing frame 7, the pressing frame 7 covers the lens plate 3 and is fixed on the radiator 1, and multiple groups of lamp beads 40 are arranged on the LED light board 2.

[0031] When the light angle needs to be adjusted, the lens plate 3 is moved left and right so that the lamp beads 40 on the LED light board 2 correspond to the angle required by the lens plate 3, and the light angle can be adjusted.

[0032] At least one pair of cylinders 8 is provided on the radiator 1, and a retractable rolling ball 9 is provided on the cylinder 8 and close to the side of the lens plate 3. Correspondingly, there are at least two pairs of circular grooves 10 on the lens plate 3 for fixing the lens plate 3. When there is no need to adjust the light angle, the ball 9 is held in the circular groove 10 of the lens plate 3, so that the lens plate 3 will not be displaced. When the lens plate 3 is moved, the ball 9 will be disengaged from the circular groove 10 and slide to another circular groove 10 on the lens plate 3.

[0033] Specifically, the circular groove 10 includes a first circular groove 11, a second circular groove 12, a third circular groove 13 and a fourth circular groove 14, and the ball 9 includes a first ball 15 and a second ball 16. When the light angle needs to be adjusted to 45*110, it is only necessary to move the lens plate 3. The displacement of the lens plate 3 will hold the first ball 15 in the first circular groove 11 and the second ball 16 in the second circular groove 12. When the light angle needs to be adjusted to 90*90, it is only necessary to move the lens plate 3. The displacement of the lens plate 3 will cause the first ball 15 and the second ball 16 to separate from the first circular groove 11 and the second circular groove 12 and slide to the third circular groove 13 and the fourth circular groove 14.

[0034] The lens plate 3 also includes a dial 17. Correspondingly, a display window 18 is provided on the pressure frame 7 at a position corresponding to the dial 17. The corresponding light angle can be displayed through the display window 18, which makes it convenient for the operator to quickly adjust to the required light angle.

[0035] The lens plate 3 includes a lens body 19, which includes a first surface and a second surface. The first surface is arranged opposite to the second surface. The first surface includes an outer lens 20. An inner lens 21 is arranged at a position corresponding to the outer lens 20 on the second surface. The outer lens 20 and the inner lens 21 are roughly in the shape of long strips. The inner lens 21 protrudes toward the side of the LED light board 2, and the outer lens 20 protrudes outward toward the side away from the LED light board 2. The light emitted by the lamp bead 40 is first diffused by the inner lens, and then focused by the outer lens 20 and emitted to the outside world.

[0036] Specifically, when the light emitted by the lamp bead 40 first passes through the inner lens 21 to mix the light, that is, to break up the light spot and prevent color difference. Since the inner lens 21 is a convex surface toward the side of the LED light board 2, that is, the inner lens 21 forms a long convex surface toward the side of the LED light board 2. The light emitted by the lamp bead 40 will pass through the inner lens 21 and refract to the side of the outer lens 20 away from the lamp bead and mix together toward the middle of the inner lens 21, that is, the light emitted by the lamp bead 40 is refracted from the inner lens 21 to the middle position away from the LED light board 2 and from the peripheral position of the inner lens 21 toward the side of the LED light board 2 to the side away from the LED light board 2 and refracted toward the middle of the inner lens 21 to mix the light. The light spot after mixing is uniform and has no color difference. At the same time, because the light spot has passed the first mixing process, it becomes soft and can reduce glare. The light spot after mixing is then re-aggregated through the outer lens 20 to form light without color difference and meeting the anti-glare requirements and transmitted to the outside world. Because the light is dispersed by the inner lens 21 in the first process, it is uniform, without color difference and soft. The light collected by the outer lens 20 is even softer and does not glare. The outer lens 20 in the present invention is equivalent to a long convex lens. After passing through the inner lens 21 to disperse the light emitted by the lamp beads 40, it is re-collected by the convex lens to form a more uniform light without color difference, which also meets the anti-glare requirements.

[0037] The outer lens 20 and the inner lens 21 are integrally formed, or the outer lens 20 and the inner lens 21 can be assembled together from two separate components.

[0038] The inner lens 21 includes a first inner lens 22 and a second inner lens 23 . The first inner lens 22 and the second inner lens 23 are convex planes.

[0039] The outer lens 20 includes a first outer lens 24 and a second outer lens 25 . The first outer lens 24 and the second outer lens 25 are respectively convex arc-shaped surfaces, and the second outer lens 25 is higher than the first outer lens 24 .

[0040] The first outer lens 24 is composed of a plurality of lens portions 26 arranged in an array.

[0041] The lens plate 3 is roughly rectangular, and a mounting plate 27 and at least one force-applying portion 28 are provided on the edge of the lens body 19. The mounting plate 27 is movably connected to the groove wall 6, and the force-applying portion 28 is used to push the lens plate 3 to move left and right.

[0042] like Figure 6 As shown, when the force applying portion 28 on the right is pushed ( Figure 6The direction of the paper is used as a reference, the upper side is right, and the lower side is left), when it is moved to the right, the lens plate 3 can be moved to the right, and the first inner lens 22 is correspondingly set above the lamp bead 40, and the lamp bead 40 on the LED light board 2 is set below the first inner lens 22. The light emitted by the lamp bead 40 passes through the first inner lens 22, and the first inner lens 22 breaks up the light spot, and then converges through the first outer lens 24. The angle of the refracted light is 90*90 degrees; when the force-applying part 8 on the left is pushed to move to the left, the lens plate 3 can be moved to the left, and the second inner lens 23 is correspondingly set above the lamp bead 40, and the lamp bead 40 on the LED light board 2 is set below the second inner lens 23. The light emitted by the lamp bead 40 passes through the second inner lens 23 to break up the light spot, and then converges through the second outer lens 25. The angle of the refracted light is 45*110 degrees.

[0043] A power supply box cover 29 is provided on the back of the radiator 1 , and the driving power supply 4 is installed in the power supply box cover 29 .

[0044] A power controller 30 and a color temperature controller 31 are further installed in the power box cover 29 . The power controller 30 and the color temperature controller 31 are installed in a switch box 32 . The bottom of the switch box 32 is fixed on the radiator 1 .

[0045] The power controller 30 includes a switch base 33, a first electronic switch 34, and a first handle 35. The first electronic switch 34 is fixedly mounted on the switch base 33 and is electrically connected to the driving power supply 4 and the LED light board 2, respectively. The first handle 35 is connected to the first electronic switch 34 and is used to be toggled to change the state of the first electronic switch 34.

[0046] The color temperature controller 31 includes the switch base 33, a second electronic switch 36, and a second handle 37. The second electronic switch 36 is fixedly mounted on the switch base 33. The second electronic switch 36 is electrically connected to the driving power supply 4 and the LED light board 2, respectively. The second handle 37 is connected to the second electronic switch 36. The second handle 37 is used to be toggled to change the state of the second electronic switch 36.

[0047] A handle cover 1 38 is fixed to the first handle 35 of the power controller 30, and a handle cover 2 39 is fixed to the second handle 37 of the color temperature controller 31. The ends of the handle cover 1 38 and the handle cover 2 39 away from the first electronic switch 34 and the second electronic switch 36 can extend out of the power box cover 29 to facilitate the user to turn the first handle 35 and the second handle 37.

[0048] The beneficial effects of the above embodiment: When adjusting the light angle of the LED lamp of the present invention, there is no need to replace the lens plate 3. It is only necessary to manually push and pull the force-applying part 28 of the lens plate 3 to move the lens plate 3 left and right, so that the lamp beads 40 on the LED lamp board 2 can correspond to the required light angle on the lens plate 3, saving the cost of purchasing the lens plate.
