[0069] A fixing arm is fixedly arranged on the lamp housing 2, and the mounting bracket 1 is fixedly arranged on the fixing arm by means of an M6 hexagon socket screw.

[0070] The LED lamp panel 7 can be composed of white light LED lamp groups 71 with different color temperatures, and can also be composed of LED lamp groups 71 of different colors + white light LED lamp groups 71. By controlling the brightness ratio of different LED lamp groups 71, a lighting effect with natural and smooth color temperature and brightness changes is generated.

[0071] In a specific implementation, the number and shape arrangement of the different LED light groups 71 in the LED light panel 7 can be specifically selected and set according to the requirements for brightness and color temperature changes.

[0072] As a specific implementation, the LED lamp panel 7 is composed of two groups of white light LED lamp groups 71 with high color temperature and low color temperature, and the number of them is the same. The optional range of the high color temperature group is 5000-8000k, and the optional range of the low color temperature group is 2700-4000k. By adjusting the brightness ratio of the LED lamp groups 71 with different color temperatures, the effect of changing the color temperature is achieved.

[0073] When the brightness of the low color temperature lamp group 71 gradually approaches 100% from 0, and the brightness of the high color temperature lamp group 71 gradually approaches 0 from 100%, the color temperature value gradually decreases, and the visual experience is that the light color gradually becomes warmer;

[0074] When the brightness of the low color temperature lamp group 71 gradually approaches 0 from 100%, and the brightness of the high color temperature lamp group 71 gradually approaches 100% from 0, the color temperature value gradually increases, and the visual experience is that the light color gradually becomes colder;

[0075] When the low color temperature lamp group 71 and the high color temperature lamp group 71 maintain synchronous brightness changes, the brightness changes more and the color temperature changes little.

[0076] This implementation is suitable for occasions where only white light lamp beads are used. The total brightness is high and the color temperature variation range is relatively small.

[0077] As a specific implementation, the LED lamp panel is composed of R (red) G (green) B (blue) W (white) four-color LED lamp groups or R (red) B (blue) W (white) lamp groups, and the number of various lamp groups is the same, among which the color temperature of the W lamp group can be selected in the range of 5500-6000k.

[0078] This implementation method is suitable for occasions where fountain lights with four colors of R (red), G (green), B (blue), and W (white) are needed. In fact, only three colors of R (red), B (blue), and W (white) are needed. The characteristics are that the color temperature changes greatly and the total brightness is relatively low. In addition, this implementation method consumes less power because only one-quarter of the white LED lamp group of the entire lamp plus a part of the other color LED lamp groups need to work at the same time. The actual power consumption generally does not exceed 30% of the total power of the lamp.

[0079] As a specific implementation, the arrangement of the LED light groups on the LED light panel can be in a ring shape or a cross shape;

[0080] The arrangement of the LED lamp beads in the LED lamp group can be a ring shape or a cross shape, and the LED lamp beads constituting the LED lamp group can be the same type of LED lamp beads or different types of LED lamp beads.

[0081] It should be noted that the color temperature changing method of the present application presents the effect of stepless color temperature change, will not produce color temperature discontinuity, the color temperature change process is natural and smooth, and can maximize the presentation of the rich and natural color temperature changes in nature.

[0082] The light emitted by the lamp shines on the water body of the waterscape, making the water body have variable brightness and color temperature changes.

[0083] The present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention.
