[0029] To further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0030] Refer to Figures 1 to 5 As shown, the present utility model discloses a ceiling lamp, including a lens 11 and a lamp board 2. The ceiling lamp may also include structures such as a lampshade and a bottom plate according to the lamp design, which will not be elaborated here. In the present utility model, the lens 11 is annular, and a tunnel structure 110 for accommodating lamp beads is provided in the lens 11. The inner side and the outer side of the tunnel structure 11 form a light incident surface and a light exit surface, and both the light incident surface and the light exit surface of the lens 11 are free-form surfaces. At least one row of lamp beads 21 with different color temperatures is provided on the lamp board 2 corresponding to the position of the lens 11, and the lamp beads 21 are all accommodated in the tunnel structure 11 of the lens 11. Since lamp beads 21 with different color temperatures are arranged on the lamp board 2, during use, by selecting different color temperature values on the color temperature adjustment button 12, the corresponding light source driving circuit will adjust the brightness (i.e., power) of the lamp beads 21 with different color temperatures, thereby realizing the adjustment of the color temperature.

[0031] Since the lens 11 is an annular structure, the light distribution is uniform within the entire annular region. Different from one lamp bead 21 corresponding to one lens 11 in the background art, the production process of the present utility model is relatively simple, and a variety of lamp beads 21 with different color temperatures can be arranged therein, and the number of lamp beads 21 is not limited. The lens 11 adopts a tunnel structure to accommodate the lamp beads 21, and uses the free-form surface design to change the refractive index distribution of the lens 11, so that light propagates inside the lens 11 in different ways, thereby changing the illuminance distribution and achieving the effect of uniform light spots. Moreover, the lens 11 adopts a tunnel structure, and the arrangement form and number of the lamp beads 21 accommodated therein can be flexibly changed, so that the lens 11 can be applied to the lamp board 2 with different arrangements of lamp beads 21, having wide applicability.

[0032] The lens 11 is provided on the lens mounting plate 1, and a color temperature adjustment button 12 for adjusting the color temperature of the ceiling lamp is also provided on the lens mounting plate 1. During use, the user can directly select the desired color temperature value through the color temperature adjustment button 12.

[0033] The lens 11 is annularly arranged at a position close to the periphery of the lens mounting plate 1, so there is space in the center of the lens mounting plate 1 for arranging a light source driving circuit. The color temperature adjustment button 12 is electrically connected to the light source driving circuit, thereby controlling the color temperature by controlling the circuit current.

[0034] In this embodiment, a power adjustment button 13 is further provided on the lens mounting plate 1. The power adjustment button 13 is electrically connected to the light source drive circuit. The user can select the desired power through the power adjustment button 13 to adjust the brightness of the ceiling lamp accordingly.

[0035] To achieve adjustable color temperature, the lens 11 needs to be equipped with lamp beads 21 of different color temperatures. Therefore, a frosted structure is further provided on the lens 11 of this embodiment, so that the light incident surface on the inner side of the lens forms a frosted surface. The frosted structure uses the principle of light scattering to enable the mixing of lamp beads 21 of different color temperatures to also achieve the effect of uniform light spot.

[0036] In this embodiment, the lens 11 is an incoherent ring structure, and a number of interruptions 14 are provided in the circumferential direction of the lens 11, so that the manufacturer can flexibly design the layout on the lens mounting plate 1. Specifically, the interruptions 14 can be provided with the inlet of the light source drive circuit and the installation location. This makes the structure of the ceiling lamp more compact, and the interruptions 14 avoid the lens 11 area and do not block the light.

[0037] In this embodiment, the lamp beads 21 of different color temperatures are arranged at intervals, which can better realize the adjustment of mixed light of different colors, and the lamp board 2 is provided with double-row lamp beads. In other embodiments, the arrangement of the lamp beads 21 is not limited to this, and only needs to be correspondingly accommodated in the tunnel structure of the lens 11.

[0038] Refer to Figure 6 、 Figure 7 The ceiling lamp lens 11 of the present invention covers the lamp board 2. The light of the lamp beads 21 is refracted through the lens 11, so that the light spot of the ceiling lamp is evenly mixed, the light is soft, the brightness is uniform, and it has the functions of adjustable color temperature and power, and has a variety of lighting modes, which is convenient and flexible to use.

[0039] The above is only one embodiment of the present invention, and it is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
