[0075] The implementation, functional features, and advantages of the present utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings. Detailed implementation manners

[0076] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0077] Referring to "embodiment" herein means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of the present utility model. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0078] Refer to Figures 1 to 4 , the embodiment of the present utility model provides a lighting lamp circuit with multiple working modes, including: a controller, a first lamp control circuit, and a second lamp control circuit. The first lamp control circuit includes a first lamp strip control circuit and a first lamp strip 101. The first lamp strip 101 includes multiple first lamp beads. The controlled end of the first lamp strip control circuit is connected to the first control end of the controller, and the control end of the first lamp strip control circuit is connected to the first lamp strip 101 to adjust and control the first lamp beads. The second lamp control circuit includes a second lamp strip control circuit and a second lamp strip 201. The second lamp strip 201 includes multiple second lamp beads. The controlled end of the second lamp strip control circuit is connected to the second control end of the controller, and the control end of the second lamp strip control circuit is connected to the second lamp strip 201 to adjust and control the second lamp beads.

[0079] Specifically, as shown in Figure 1 and Figure 2 , the controller is respectively connected to the first lamp control circuit and the second lamp control circuit through two control signal terminals. In this way, the controller can control the working modes of the first lamp control circuit and / or the second lamp control circuit. As shown in Figure 3As shown in the figure, the power supply circuit of the first light bar 101 can be switched on and off through the first lamp control circuit, and then the first lamp beads can be controlled to be lit or extinguished. At the same time, when the switching control frequency of the first lamp control circuit is relatively fast, the average current flowing through the first lamp beads is in arithmetic relationship with the pulse width, so that the brightness of the first lamp beads can be controlled. In this way, the on / off or brightness adjustment control of the first lamp beads can be realized through the first light bar control circuit. Since the first light bar 101 includes multiple first lamp beads. In this way, under the action of the first light bar control circuit, multiple first lamp beads can be simultaneously controlled for synchronous on / off and brightness adjustment. Similarly, as Figure 4 shown in the figure, under the action of the second light bar control circuit, multiple second lamp beads can be simultaneously controlled for synchronous on / off and brightness adjustment. In this way, through the controller, the on / off and brightness adjustment of the lamp beads of the two light bars can be realized. In this way, the control of multiple lighting working modes of the lighting lamp can be realized. For example, when the first lamp beads and the second lamp beads are arranged in a cross pattern, the movement change of the light can be realized by cross-controlling the on / off and / or brightness of the first lamp beads and the second lamp beads, similar to the dazzling flashing mode of the "horse race" movement. Since in the embodiment of the present invention, the first light bar control circuit and the second light bar control circuit are controlled by the controller, and the first light bar 101 and the second light bar 201 are controlled by the first light bar control circuit and the second light bar control circuit, the circuit structure is simple, greatly increasing the stability and reliability of the circuit, and at the same time reducing the production cost of the overall circuit.

[0080] Referring to Figure 3 , the first lamp control circuit further includes a third light bar control circuit and a third light bar 102. The controlled end of the third light bar control circuit is connected to the third control end of the controller. The third light bar 102 includes multiple third lamp beads. The control end of the third light bar control circuit is connected to the third light bar 102 to adjust and control the third lamp beads; wherein, the first lamp beads and the third lamp beads are lamp beads of different light colors, and one or more of the first lamp beads and one or more of the third lamp beads form a first mixed light display lamp bead 103; as Figure 3 shown in the figure, in an embodiment of the present invention, mixed lamp beads can also be formed by lamp beads of different light colors of two light bars. Since a mixed lamp bead can be composed of two lamp beads of different light colors, and the two lamp beads of different light colors are respectively controlled by different light bar control circuits. In this way, through the mixing of different emission brightnesses of the two lamp beads of different light colors, different color temperatures can be mixed, making the lighting color / color temperature more rich. During use, the lighting color / color temperature can be adjusted and controlled according to different application scenarios.

[0081] Referring toFigure 4 , the second lamp control circuit further includes a fourth lamp strip control circuit and a fourth lamp strip 202. The controlled end of the fourth lamp strip control circuit is connected to the fourth control end of the controller. The fourth lamp strip 202 includes multiple fourth lamp beads. The control end of the fourth lamp strip control circuit is connected to the fourth lamp strip 202 to adjust and control the fourth lamp beads. Among them, the second lamp beads and the fourth lamp beads are lamp beads of different bright colors. One or more of the second lamp beads and one or more of the fourth lamp beads form a second mixed light display lamp bead 203. As Figure 4 shown, in an embodiment of the present invention, mixed lamp beads can also be formed by lamp beads of different bright colors of two lamp strips. Since one mixed lamp bead can be composed of two lamp beads of different bright colors, and the two lamp beads of different bright colors are respectively controlled by different lamp strip control circuits. In this way, by mixing the two lamp beads of different bright colors with different luminous brightnesses, different color temperatures can be mixed, making the lighting color / color temperature richer. When in use, the lighting color / color temperature can be adjusted and controlled according to different application scenarios. At the same time, when the first mixed light display lamp bead 103 and the second mixed light display lamp bead 203 are arranged crosswise, the movement change of the light can be realized by cross-controlling the on / off, light brightness or color / color temperature of the first mixed light display lamp bead 103 and the second mixed light display lamp bead 203, similar to the dazzling flashing mode of the "horse race" movement.

As Figure 3 shown, the third mixed light display lamp bead 106 is connected in parallel with the first mixed light display lamp bead 103. The on / off, light brightness or color / color temperature can be synchronously adjusted and controlled under the action of the first lamp strip control circuit and the third lamp strip control circuit respectively. In this way, by the first mixed light display lamp bead 103 and the third mixed light display lamp bead 106 connected in parallel, the number of the overall lamp strips can be increased. On the other hand, the first lamp strip 101, the third lamp strip 102, the fifth lamp strip 104 and the sixth lamp strip 105 can be connected with different current limiting resistors, so that the first mixed light display lamp bead 103 and the third mixed light display lamp bead 106 can have different color temperatures, making the light display richer.

[0083] Refer to Figure 4 , the second lamp control circuit further includes: a seventh lamp strip 204 and an eighth lamp strip 205. The seventh lamp strip 204 includes a plurality of seventh lamp beads. The control end of the second lamp strip control circuit is further connected to the seventh lamp strip 204 to adjust and control the five lamp beads; the eighth lamp strip 205 includes a plurality of eighth lamp beads.

[0087] As Figure 3 and Figure 6 shown in, the structure of the fourth lamp control circuit is basically the same as that of the first lamp control circuit, and its working principle is also basically the same. Details are not repeated here. By the first lamp control circuit, the second lamp control circuit, the third lamp control circuit and the fourth lamp control circuit, the control of four groups of mixed display lamp beads can be realized. When the first mixed light display lamp bead 103, the second mixed light display lamp bead 203, the third mixed display lamp bead and the fourth mixed display lamp bead are arranged crosswise, the on / off, light brightness or color / color temperature of the first mixed light display lamp bead 103, the second mixed light display lamp bead 203, the third mixed light display lamp bead 106 and the third mixed light display lamp bead 106 can be cross-controlled to realize the movement change of the light, similar to the dazzling and flashing mode of the "horse race" movement.

As Figure 2 and Figure 3 shown in, when the controller needs to turn on the first light bar 101 and the third light bar 102, a high-level signal can be sent through the IQ1 signal terminal. This high-level signal can turn on the triode Q1, and then can control the MOS transistor V1 to turn on, output the DC power supply VBUS to supply power to the first light bar 101 and the third light bar 102, so that the first light bar 101 and the third light bar 102 can be turned on simultaneously.
