Embodiment 1
[0041] like Figure 1 to Figure 3 and Figure 4b As shown, this embodiment provides an LED lighting device, including a substrate 10, a sub-light-emitting area 11 disposed on the substrate 10; 36 LED lamps are arranged in the sub-light-emitting area 11; each of the sub-light-emitting areas 11 Independently controlled lead wires 13 and driving units 14 are provided; the driving unit 14 corresponding to each sub-light-emitting area 11 controls the on / off of the LED lights in the sub-light-emitting area through the lead wires 13 .
[0042] The distribution shape of the LED lamps 12 in the sub-light-emitting area 11 follows the arrangement shape of the sub-light-emitting area 11, that is, the outline shape of the distribution shape of the LED lamps 12 is consistent with the layout shape of the sub-light-emitting area 11, and The common center point is, for example, a right-angled triangle, except that the distribution contour shape of the LED lights 12 is nested in the sub-light-...
Embodiment 2
[0088] like Figure 35-39 As shown, this embodiment provides a vehicle lamp 40, the vehicle lamp is formed by splicing the LED lighting device in Embodiment 1, for example, made of figure 1 The first LED lighting device 51 shown and Figure 35 The second LED lighting device 52 shown is formed by fixed connection through the alignment of the mounting holes 15 Figure 36 lights shown.
[0089] Correspondingly, the independent control of different sub-light-emitting regions of different LED lighting devices can form a "display" pattern to realize the interaction of vehicle lights. such as Figure 37 When the lamp shown is used as a left rear lamp, when the sub-light-emitting area of the shadow part in the lamp is illuminated, a prompt pattern of the vehicle to "turn left" can be realized, such as: Figure 38 When the car light shown is used as the right rear light, when the sub-light-emitting area of the shadow part in the light is lit, the prompt pattern of the car to "...
