DETAILED DESCRIPTION
[0046] Reference Figures 1 to 13The preferred embodiment of the utility model shown is: an LED lamp, comprising a lamp holder 1, an LED light board 2, a light-transmitting plate 3 and a driving power supply 4, the lamp holder 1 can have a heat dissipation function, the driving power supply 4 is installed on the lamp holder 1 and is used to supply power to the LED light board 2, the lamp holder 1 has a mounting groove 5, the LED light board 2 is installed in the mounting groove 5, the light-transmitting plate 3 covers the LED light board 2, a plurality of groups of light-emitting elements 6 are arranged on the LED light board 2, an electrical angle controller 7 is electrically connected between the LED light board 2 and the driving power supply 4, the angle controller 7 is arranged on the lamp holder 1 and is used to switch the light-emitting elements 6 at different positions of the light-transmitting plate 3 to emit light.
[0047] By setting the above-mentioned angle controller 7, when it is necessary to adjust the light angle, color temperature and power of the LED lamp, it is only necessary to turn the angle controller 7 to control the light-emitting elements 6 corresponding to different positions under the light-transmitting plate 3 to emit light.
[0048] like Figures 7 and 8 As shown, the multiple groups of light-emitting elements 6 are evenly arranged on the LED lamp board 2 in the form of multiple sectors, and there is a first gap 15 between two adjacent sectors of the multiple sectors. In the same sector, there is a second gap 16 between two adjacent rows of the light-emitting elements 6, and there is a third gap 17 between each group of light-emitting elements 6.
[0049] Each group of light emitting elements 6 includes a first lamp bead 11, a second lamp bead 12, a third lamp bead 13 and a fourth lamp bead 14. The spacing between the first lamp bead 11 and the second lamp bead 12, and between the third lamp bead 13 and the fourth lamp bead 14 is 8 mm-11 mm, for example, 10 mm, to achieve a good lighting effect. The spacing between the first lamp bead 11 and the fourth lamp bead 14, and between the second lamp bead 12 and the third lamp bead 13 is 7 mm-9 mm, for example, 8.2 mm, to achieve a good lighting effect.
[0050] The color temperature value of the first lamp bead 11 and the second lamp bead 12 is 3000K; the color temperature value of the third lamp bead 13 and the fourth lamp bead 14 is 5000K.
[0051] like Figures 4 to 6As shown, the angle controller 7 is fixed in the fixing groove 27 of the lamp holder 1, and the angle controller 7 includes a switch base 8, an electronic switch 9 and a handle 10. The switch base 8 is fixed on the fixing groove 27, and the electronic switch 9 is fixedly installed on the switch base 8. The two ends of the electronic switch 9 are electrically connected to the driving power supply 4 and the LED light board 2 respectively, and the handle 10 is connected to the electronic switch 9.

In this way, the angle controller 7 can achieve good waterproof and dustproof effects.
[0053] like Figures 9 to 12 As shown, the light-transmitting plate 3 is a lens plate with a lens structure and is placed on the light-emitting element 6. The light-transmitting plate 3 includes a lens frame 18 and a plurality of raised lenses 19 arranged on the lens frame 18. The plurality of raised lenses 19 are arranged corresponding to the light-emitting element 6 and the raised direction is away from the light-emitting element 6. The lens frame 18 is provided with a plurality of through holes 20 corresponding to the plurality of lenses 19.
[0054] The multiple raised lenses 19 are evenly arranged in a circular ring around the axis of the lens frame 18 on the lens frame 18, the center of each circular ring is the same, a fourth gap 21 is provided between two adjacent circular rings, and a fifth gap 22 is provided between two adjacent lenses 19 of the same circular ring, the radius of the circular ring close to the axis of the lens frame 18 is the smallest, and then the radius of the circular ring increases successively.
[0055] The lens 19 has a first lens 29, a second lens 30, a third lens 31, and a fourth lens 32 protruding from one side of the lens 19 away from the light emitting element 6 and corresponding to the positions of the first lamp bead 11, the second lamp bead 12, the third lamp bead 13, and the fourth lamp bead 14, respectively. A groove 23 is provided on the second lens 30 and the fourth lens 32 and away from the second lamp bead 12 and the fourth lamp bead 14. Of course, the groove 23 of the present invention can also be provided on the first lens 29 and the third lens 31 and away from the first lamp bead 11 and the third lamp bead 13.

[0056] like Fig.13As shown, the first lens 29, the second lens 30, the third lens 31, and the fourth lens 32 on the lens 19 are equivalent to forming a plurality of convex lenses. The light emitted by the light-emitting element 6 passes through the light-entering surface of the lens 19, and then is focused by a plurality of convex lenses and emitted to the outside. Since the more convex the convex lens, the smaller the focal length, the focus of each convex lens is not in the same position. In the utility model, the entire surface of the first lens 29 and the third lens 31 on the lens 19 corresponding to the first lamp bead 11 and the third lamp bead 13 is a convex surface, and the angle of the refracted light is 60°. A groove 23 is provided on the second lens 30 and the fourth lens 32 corresponding to the second lamp bead 12 and the fourth lamp bead 14, and the angle of the light refracted by the groove 23 is 110°. In this way, when the light emitted by the second lamp bead 12 and the fourth lamp bead 14 passes through the light incident surface of the lens 19, and is then focused by the second lens 30 and the fourth lens 32 and emitted to the outside, the angle of the light can be 60°. Due to the provision of the groove 23, when the light emitted by the first lamp bead 11 and the third lamp bead 13 passes through the light incident surface of the lens 19, and is then focused by the second lens 30 and the fourth lens 32 and emitted to the outside, the angle of the light is 110°, that is, the focal length of the second lens 30 and the fourth lens 32 is greater than that of the first lens 29 and the third lens 31, and the angle of the light passing through the second lens 30 and the fourth lens 32 is also greater than that of the first lens 29 and the third lens 31.
[0057] When it is necessary to select and adjust to the required state, it is only necessary to toggle the handle 10 of the angle controller 7 so that the electronic switch 9 is in the corresponding state, which is specifically as follows:
[0058] When the electronic switch 9 is in the first state (i.e. the light angle is 60° and the color temperature is 3000K), the first lamp bead 11 emits light;
[0059] When the electronic switch 9 is in the second state (i.e. the light angle is 60° and the color temperature is 4000K), the first lamp bead 11 and the third lamp bead 13 emit light;
[0060] When the electronic switch 9 is in the third state (i.e. the light angle is 60° and the color temperature is 5000K), the third lamp bead 13 emits light;
[0061] When the electronic switch 9 is in the fourth state (i.e., the light angle is 90° and the color temperature is 3000K), the first lamp bead 11 and the second lamp bead 12 emit light;
[0062] When the electronic switch 9 is in the fifth state (i.e., the light angle is 90°, the color temperature is 4000K), the first lamp bead 11, the second lamp bead 12, the third lamp bead 13 and the fourth lamp bead 14 all emit light;
[0063] When the electronic switch 9 is in the sixth state (i.e., the light angle is 90°, the color temperature is 5000K), the third lamp bead 13 and the fourth lamp bead 14 emit light;
[0064] When the electronic switch 9 is in the seventh state (i.e., the angular light intensity is 110°, the color temperature value is 3000K), the second lamp bead 12 emits light;
[0065] When the electronic switch 9 is in the eighth state (i.e., the light angle is 110°, the color temperature is 4000K), the second lamp bead 12 emits light and the fourth lamp bead 14 emits light;
[0066] When the electronic switch 9 is in the ninth state (ie, the light angle is 110° and the color temperature is 5000K), the fourth lamp bead 14 emits light.
[0067] like Figure 3 As shown, it also includes a sealing ring 28 arranged between the light-transmitting plate 3 and the LED light board 2. A good waterproof effect can be achieved.
[0068] like Figures 1 to 4 As shown, it also includes a hanging ring 24 installed on the driving power supply 4 for installing the LED lamp.
[0069] The beneficial effects of the above embodiments are as follows: the utility model does not need to replace the lens plate, and the light angle, color temperature and power of the LED lamp can be adjusted by simply turning the angle controller 7, which saves the cost of replacing the lens plate 3 and is safer and more reliable.
