Two power modules 12 are respectively disposed on two sides of the bottom of the base 11, and each power module 12 may include a battery holder 121 and at least one battery 122; wherein, the battery fixing seat 121 is disposed at a position substantially corresponding to the battery mounting hole 112; the upper surface of the battery holder 121 is provided for installing the battery 122, a sealing ring (not shown in fig. 2) may be disposed on the battery holder 121 around the battery 122, and then the battery holder 121 is installed and fixed on the base 11 from bottom to top, and the battery 122 passes through the battery installation hole 112, so that the battery 122 is located on the base 11, and the sealing ring is used to prevent water or other liquid from permeating into the battery holder 121. The bottom surfaces of the base 11 and the battery holder 121 may be provided with double-sided tapes, and the base 11 and the battery holder 121 may be adhered and fixed to the car threshold 3 through the double-sided tapes. The battery 122 may be a button-type lithium battery. When the battery 122 is to be replaced, the double-sided tape directly adhering the base 11 and the battery holder 121 to the car threshold 3 is torn off, and after the battery is replaced, a new double-sided tape is adhered again to the car threshold 3.

The circuit board module 13 is installed in the groove 111 of the base 11, a set of light emitting modules 132 are respectively disposed on two symmetrical sides of the circuit board 130 of the circuit board module 13, and a conductive part 131 is respectively electrically connected to two ends of the circuit board 130, so that the conductive part 131 is located outside two ends of the groove 111 and respectively extends to the positions of the battery installation holes 112 at the two ends; the conductive parts 131 at the two ends can be electrically connected to the battery 122, respectively, so that the current supplied by the battery 122 can be provided to the circuit of the circuit board 130 and the light emitting module 132 through the conductive parts 131.

The light module 132 includes a red LED132A, a green LED132B, and a blue LED132C, and preferably, the red LED132A, the green LED132B, and the blue LED132C are packaged on a substrate and located in a housing to form a light module 132.

The reflective paper 14 is arranged on the circuit board 130. The light guide plate 15 is disposed on the reflective paper 14, and opposite ends of the light guide plate 15 correspond to the light emitting modules 132 (as shown in fig. 3), so that light emitted from the light emitting modules 132 is projected into the light guide plate 15 from the end edge of the light guide plate 15 for conduction. The light transmitting paper 16 is provided on the light guide plate 15. The surface material 17 is provided above the base 11 and covers the light-transmitting paper 16.

The circuit board module 13 is controlled by a controller (not shown) to emit light from the red LED132A, the green LED132B, and the blue LED132C of the light emitting module 132 at the same time or at a specific timing or randomly, and the emitted light is projected into the light guide plate 15 from both ends of the light guide plate 15 along the length direction to be conducted, so as to generate mixed light colors and generate a visual effect of light flowing inside the light guide plate 15. The light emission of the red LED132A, the green LED132B and the blue LED132C is controlled by a control circuit of a microchip of the controller and a program stored in a memory, and the controller can control the light emission intensity of the red LED132A, the green LED132B and the blue LED132C according to a predetermined setting.

For example, if the controller controls the two sets of light emitting modules 132 to project red light from two ends of the light guide plate 15 to the inside by the red LEDs 132A, the light guide plate 15 will only emit a single red light; if the controller controls the two sets of light emitting modules 132 to respectively project green light from the two ends of the light guide plate 15 to the inside by the green LEDs 132B, the light guide plate 15 will only emit single green light; if the controller controls the two sets of light emitting modules 132 to project blue light from two ends of the light guide plate 15 to the inside by the blue LEDs 132C, the light guide plate 15 will only emit a single blue light. If the red LED132A and the green LED132B of one group of light emitting modules 132 simultaneously project red light and green light from the first end of the light guide plate 15 to the inside, and the green LED132B and the blue LED132C of the other group of light emitting modules 132 simultaneously project green light and blue light from the second end of the light guide plate 15 to the inside, the red light and the green light projected from the first end will be mixed into yellow light, and the brightness decreases from the first end to the second end due to the light transmission distance; the green light and the blue light projected from the second end of the light guide plate 15 will be mixed into the cyan light, and the brightness decreases from the second end to the first end due to the light transmission distance; the cyan light and the yellow light are mixed into light with a light green color at the middle position of the light guide plate 15 (since the two sets of light emitting modules 132 simultaneously project the green light, the green light is more). In addition, the controller may control the LEDs of other colors to emit light in different combinations, or simultaneously, or at a specific time sequence, or randomly according to a predetermined setting, so as to generate a variable light mixing effect inside the light guide plate 15 and change the color.

Furthermore, the utility model discloses also can utilize the controller to control two sets of light emitting module 132 with the same or power emission light of inequality intensity to build the visual effect that light flows at light guide plate 15. For example, when each LED of one of the light emitting modules 132 emits a strong light and each LED of the other light emitting module 132 emits a weak light, a relatively bright light emitted from the light emitting module 132 at the first end is generated in a direction from the first end to the second end of the light guide plate 15, and a relatively dark light emitted from the light emitting module 132 at the second end is generated in a direction from the second end to the first end of the light guide plate 15; the stronger or weaker light emitted from the first and second ends of the light guide plate 15 may be controlled to vary at a predetermined timing or randomly, thereby visually generating an effect of varying the flow of light in the light guide plate 15. Part of the light transmitted in the light guide plate 15 directly passes through the light transmitting paper 16 and the surface material 17, and part of the light is reflected by the reflective paper 14 and passes through the light guide plate 15, the light transmitting paper 16 and the surface material 17, so that a welcome pedal capable of changing light effects is presented on the surface of the surface material 17.
