[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] like Figure 3 As shown, an integrated mixed-color diffuse reflection lamp sheet is provided, including a lamp sheet plate, on which four lamp bead bodies and a driving chip are mounted.

[0024] like Figure 1 and 2 As shown, the lamp bead body includes a substrate 1, on which are arranged four colors of red (Red), green (Green), blue (Blue) and white (White) color powder lamp beads 2, there are multiple color powder lamp beads 2 of the same color, all of which are in granular form and are distributed in an array on the substrate 1, and the color powder lamp beads 2 of the same color are not adjacent. Therefore, the red (Red) color powder lamp beads 2 can be evenly distributed on the substrate 1, the green (Green) color powder lamp beads 2 can be evenly distributed on the substrate 1, the blue (Blue) color powder lamp beads 2 can be evenly distributed on the substrate 1, and the white (White) color powder lamp beads 2 can be evenly distributed on the substrate 1.

[0025] A layer of encapsulation resin layer 4 is coated on the substrate 1, and the outer side of the encapsulation resin layer 4 is set as a convex surface. The encapsulation resin layer 4 can not only fix the position of the toner lamp bead 2, but also has good polarization optical properties to improve the clarity of the light. It should be noted that the polarization optical properties of the encapsulation resin layer 4 are its own properties and are prior art, and are not within the scope of protection of the present utility model, and are only used for those skilled in the art to understand the application of the encapsulation resin layer 4.

[0026] An optical refraction plate 3 is disposed outside the encapsulation resin layer 4, and the optical refraction plate 3 is adhered to the substrate 1. It should be noted that the optical refraction plate 3 has the refraction and convergence characteristics of light, which is a characteristic of the optical refraction plate 3 itself and is a prior art, and is not within the scope of protection of the present utility model, and is only used for those skilled in the art to understand the application of the optical refraction plate 3.

[0027] Furthermore, a positioning through hole 6 is provided at the center of the light sheet plate for use as a positioning reference during installation and fixation to avoid damage to the light sheet during rigid fixation.

[0028] All the color powder lamp beads 2 of the same lamp bead body are connected in series in sequence through the circuit on the substrate 1, and then connected to the current control circuit through the two column feet 5 on the lower side of the substrate 1 to form a loop, such as Figure 4 shown.

[0029] The current control circuit includes multiple driver chips and a controller, one driver chip drives four lamp bead bodies, and one color-mixing diffuse reflection lamp sheet includes four lamp bead bodies. It should be noted that in this embodiment, one color-mixing diffuse reflection lamp sheet has one driver chip and four lamp bead bodies, but the technical solution of one color-mixing diffuse reflection lamp sheet having two driver chips and eight lamp bead bodies (or three driver chips and twelve lamp bead bodies) is also within the protection scope of the present utility model.

[0030] like Figure 4 As shown, the driver chip has four power-on channels, and each power-on channel of the driver chips U1 and U2 is electrically connected to a lamp bead body (the color powder lamp bead 2 inside is connected in series) and connected to the power supply voltage VCC. A current-limiting resistor R is connected between the lamp bead body and the power supply voltage VCC. The differential control input terminals A and B of the driver chips U1 and U2 are connected to the differential control output terminals A / D+ and B / D- of a controller through and. The driver chips U1 and U2 are electrically connected through the code writing output terminal PO, resistor, resistor and code writing input terminal PI. Therefore, the control timing of the driver chips U1 and U2 is the same, that is, the same program is maintained, that is, the same output voltage duty cycle design program is maintained.

[0031] The output voltage duty cycle of the four power-on channels of the driver chips U1 and U2 alternates four times in sequence, so one power-on channel has four different output voltages, that is, four different currents are output, and the four different currents correspond to the light emission of four colors of toner lamp beads 2, so that one lamp bead body can emit mixed light of four different colors. It should be noted that the toner luminescence characteristics of the toner lamp bead 2 are its own material characteristics and are prior art, and are not within the scope of protection of the present utility model, and are only used for the understanding of the application of the toner lamp bead 2 by those skilled in the art.

[0032] It should be noted that the circuit connection relationship of the above-mentioned current control circuit is the technical solution to be protected by the present utility model, while the programs involved in the control process between the controller and the driver chip are not within the protection scope of the present utility model and are only used for technical personnel in this field to understand the application of controllers and driver chips.

[0033] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the utility model without departing from the content of the technical solution of the utility model should be included in the protection scope of the utility model.
