[0002] LED lamps have many advantages such as energy conservation, environmental protection and long service life, and have been widely used in various lighting places. Existing LED lamps usually include a lens plate, and the lens plate is generally fixed on the heat dissipation base by screwing. Since the number of screws is large and a screwdriver is needed, the assembly is not fast and convenient enough, with low efficiency and high labor cost. Since different countries or different usage places have different requirements for light distribution, it is possible that consumers will replace different types of lens plates according to their own needs. At this time, if a screwdriver is used to disassemble the light-transmitting part, it is extremely inconvenient. On the other hand, usually one lens plate has one angle. When it is necessary to adjust the light angle of the LED lamp, a lens plate needs to be replaced according to different requirements, which increases the cost of purchasing the lens plate.

Detailed implementation manners

[0030] Refer to Figures 1 to 3Embodiment of the utility model shown: A lens 1, which is used in cooperation with a light source, includes a lens body 2. The lens body 2 includes a first surface and a second surface, and the first surface and the second surface are arranged opposite to each other. The first surface includes at least one or more outer lenses, and at least one or more inner lenses are arranged at positions corresponding to the outer lenses on the second surface. The outer lenses and the inner lenses are generally strip-shaped. The inner lenses protrude towards the light source side, and the outer lenses protrude outwards away from the light source side. The light emitted by the light source first passes through the inner lenses for light scattering, and then is condensed by the outer lenses and then emitted to the outside world.

[0031] When the light emitted by the light source first passes through the inner lenses to perform light mixing treatment on the light, that is, to scatter the light spot and prevent color difference. Since the inner lenses are surfaces protruding towards the light source side, that is, the inner lenses form long strip-shaped curved surfaces towards the light source side. The light emitted by the light source will pass through the inner lenses and be refracted to the side of the outer lenses away from the light source and mixed together in the middle of the inner lenses. That is, the light emitted by the light source is refracted from the middle position of the inner lenses away from the light source side and from the peripheral position of the inner lenses towards the light source side to the side away from the light source and refracted to the middle of the inner lenses for light mixing. The light spot after light mixing is uniform and free of color difference. At the same time, since the light spot that has passed through the first light mixing program becomes soft, glare can be reduced. The light spot after light mixing is then re-aggregated by the outer lenses to form light that is free of color difference and meets the anti-glare requirements and is transmitted to the outside world. Since the light is scattered by the inner lenses in the first program, its light will be uniform, colorless, and soft, and the light re-aggregated by the outer lenses is more soft and will not cause glare. The outer lenses in the present utility model are equivalent to forming strip-shaped convex lenses. After passing through the inner lenses to scatter the light emitted by the light source, and then passing through the convex lenses to re-aggregate the scattered light to form more uniform light, without color difference, and also meeting the anti-glare requirements.

[0032] The outer lenses and the inner lenses are integrally formed, and the outer lenses and the inner lenses can also be assembled together by two separate components.

[0033] The outer lenses include a first outer lens 3 and a second outer lens 4. The first outer lens 3 is a convex plane, and the second outer lens 4 is a convex arc surface. The inner lenses include a first inner lens 5 and a second inner lens 6. The first inner lens 5 and the second inner lens 6 are respectively convex arc surfaces. The second inner lens 6 is higher than the first inner lens 5. The first inner lens 5 is composed of a plurality of lens parts 7 arranged.

[0034] When the light source is arranged at a position below the first inner lens 5, the light emitted by the light source passes through the first inner lens 5. The first inner lens 5 scatters the light spot, and then the light is aggregated by the first outer lens 3, and the refracted light angle is 45*110 degrees; when the light source is arranged at a position below the second inner lens 6, the light emitted by the light source passes through the second inner lens 6 to scatter the light spot, and then the light is aggregated by the second outer lens 4, and the refracted light angle is 90*90 degrees.

[0035] The lens 1 is generally rectangular, and a mounting plate 8 is arranged on the edge of the lens body 2. The lens 1 is movably connected to the LED lamp through the mounting plate 8.

[0036] As Figures 4 to 9 shown, the present invention also provides an LED lamp, which includes a heat dissipation base 9 and an LED lamp board 10. The front surface of the heat dissipation base 9 is provided with a mounting groove 11, and the LED lamp board 10 is mounted on the bottom of the mounting groove 11; a sliding groove 12 is also provided at the top of the mounting groove 11, and the above-mentioned lens 1 is arranged in the sliding groove 12. The lens 1 covers the LED lamp board 10. A group of lamp beads 13 are arranged on the LED lamp board 10 at a position corresponding to the first inner lens 5 or the second inner lens 6. The sliding groove 12 is provided with an insertion port 14, and the insertion port 14 is located on the side surface of the end of the heat dissipation base 9; a movable member 15 is provided at a position corresponding to the insertion port 14 on the side surface of the end of the heat dissipation base 10. The movable member 15 is fixed to the heat dissipation base 9 by screws. When the movable member 15 is in the reset state, the movable member 15 blocks the insertion port 14. When it is necessary to install or replace the lens 1, only need to unscrew the screws and move the movable member 15 away from the position of the insertion port 14 to cancel the block of the insertion port 14, and the lens 1 can be inserted or taken out from the insertion port 14.

[0037] The heat dissipation base 9 includes a middle part and two side parts located on both sides of the middle part. There are spaced holes between the middle part and the side parts. The LED lamp board 10 and the lens 1 are respectively installed in the two side parts, and a driving power supply 16 is installed in the middle part. A power supply box cover 17 is provided outside the driving power supply 16. The spaced holes can isolate the heat of the LED lamp board 10 and the driving power supply 16 from each other, and improve the service life of both.

[0038] As Figures 9 to 10 shown, a power controller 18 and a color temperature controller 19 are also installed in the middle part. The power controller 18 and the color temperature controller 19 are installed in the switch box 25, and the bottom of the switch box 25 is fixed to the heat dissipation base 9.

[0039] The power controller 18 includes a switch base 20, a first electronic switch 21, and a first handle 22. The first electronic switch 21 is fixedly installed on the switch base 20. The first electronic switch 21 is electrically connected to the drive power supply 16 and the LED lamp board 10 respectively. The first handle 22 is connected to the first electronic switch 21. The first handle 22 is used to be toggled to change the state of the first electronic switch 21.

[0040] The color temperature controller 19 includes the switch base 20, a second electronic switch 23, and a second handle 24. The second electronic switch 23 is fixedly installed on the switch base 20. The second electronic switch 23 is electrically connected to the drive power supply 16 and the LED lamp board 10 respectively. The second handle 24 is connected to the second electronic switch 23. The second handle 24 is used to be toggled to change the state of the second electronic switch 23.

[0041] A first handle cover 26 is fixed on the first handle 22 of the power controller 18, and a second handle cover 27 is fixed on the second handle 24 of the color temperature controller 19. One ends of the first handle cover 26 and the second handle cover 27 away from the first electronic switch 21 and the second electronic switch 23 can extend out of the top of the power supply box cover 17 to facilitate the user to toggle the first handle 22 and the second handle 24.

[0042] When it is necessary to adjust the light angle of the LED lamp, the specific operation is as follows:

[0043] When installing or replacing the lens 1, move the movable part 15 away from the insertion port 14 to cancel the blockage of the insertion port 14, and the lens 1 can be inserted or removed from the insertion port 14, and then a new lens 1 can be replaced. For example, when using the lens 1 of the present invention, when the LED lamp needs to be in the state of changing the angle, only rotate the removed lens 1 by 180 degrees and then insert it into the insertion port 14 so that the lamp beads 13 on the LED lamp board 10 correspond to the first inner lens 5 or the second inner lens 6.

[0044] When the lamp beads 13 on the LED lamp board 10 are correspondingly arranged below the first inner lens 5, the light emitted by the lamp beads 13 on the LED lamp board 10 is scattered by the first inner lens 5 and then condensed by the first outer lens 3, and the refracted light angle is 45 * 110 degrees.

[0045] When the lamp beads 13 on the LED lamp board 10 are correspondingly arranged below the second inner lens 6, the light emitted by the lamp beads 13 on the LED lamp board 10 is scattered by the second inner lens 6 and then condensed by the second outer lens 4, and the refracted light angle is 90 * 90 degrees.

[0046] Advantages of the above embodiments: The LED lamp of the present utility model can quickly assemble or replace the lens, and the operation is convenient. On the other hand, two angles are provided on one lens 1. When adjusting the angle, only need to manually remove the lens 1, rotate the lens 1 by 180 degrees and then install it on the LED lamp, then the light angle of the LED lamp can be changed, saving the cost of the lens 1.
