A bi-color license plate frame, for surrounding a license plate of a vehicle, comprises a rectangular body comprising an aperture that is adapted to show a license plate, and a wall defining a hollow frame space inside the wall, a plurality of light-emitting elements contained in the frame space, and a controller that is electrically connected to the light-emitting elements and that controls the light intensity of the light-emitting elements according to the braking status of the vehicle. The wall of the rectangular body is translucent to the light of the light-emitting elements, and comprises a light diffusion layer, whereby surface illumination is provided when the light-emitting elements are turned on. Bi-color may include metal look and color emitted by the light-emitting elements, or red or black color of the light-diffusion layer and color emitted by the light-emitting elements.

1. A bi-color license plate frame, for surrounding a license plate of a vehicle, comprising: a) a rectangular body comprising an aperture that is adapted to show the license plate, and a wall defining a hollow frame space inside the wall;b) a plurality of light-emitting elements contained in the frame space; andc) a controller that is electrically connected to the light-emitting elements and that controls the light intensity of the light-emitting elements;wherein the wall of the rectangular body is translucent to the light of the light-emitting elements, and comprises a light diffusion layer, whereby surface illumination is provided when the light-emitting elements are turned on, wherein the controller comprises an ambient light sensor that measures the intensity of ambient light, wherein the controller further comprises a brake sensor that is adapted to receive braking signal from the vehicle, wherein the controller controls the light intensity of the light-emitting elements according to the received braking signal, wherein when the ambient light sensor indicates that it is night time and the brake sensor indicates that that the brake is not stepped on, the controller set the light intensity at a first magnitude, wherein when the ambient light sensor indicates that it is night time and the brake sensor indicates that that the brake is stepped on, the controller set the light intensity at a second magnitude, wherein the first magnitude is lower than the second magnitude. 2. The bi-color license plate frame of claim 1, wherein the light diffusion layer is made of resin, wherein the resin comprises acrylonitrile butadiene styrene, or poly methyl methacrylate. 3. The bi-color license plate frame of claim 2, wherein the resin of the light diffusion layer is dyed in red or black color. 4. The bi-color license plate frame of claim 1, wherein the wall of the rectangular body further comprises a silver nano painting layer. 5. The bi-color license plate frame of claim 4, wherein the thickness of the silver nano painting layer is in the range of 3˜5 μm. 6. The bi-color license plate frame of claim 1, wherein the wall of the rectangular body further comprises a metal coating layer, wherein the degree of translucency is controlled with the grains of the metal coating layer. 7. The bi-color license plate frame of claim 6, further comprising a printed circuit board on which the light-emitting elements are installed, wherein the light-emitting elements comprise light-emitting diodes. 8. The bi-color license plate frame of claim 7, wherein the light emitting diodes have a light emitting angle greater than one hundred ten degree. 9. The bi-color license plate frame of claim 8, wherein the printed circuit board comprises a heat conducting plate that is adapted to contact the vehicle, whereby heat generated by the light-emitting diodes is dissipated to the vehicle. 10. The bi-color license plate frame of claim 9, wherein the light diffusion layer comprises a plurality of projections that divert light rays from the light-emitting elements. 11. The bi-color license plate frame of claim 10, further comprising a wire that is adapted to be connected to a wiring harness of the vehicle, and a fastener that is adapted to fasten the rectangular body to the vehicle and that has a space for passage of the wire. 12. The bi-color license plate frame of claim 11, wherein the fastener comprises a threaded screw that comprises a half-cylindrical body. 13. The bi-color license plate frame of claim 11, wherein the fastener comprises a cap that fits into a hole provided on the rectangular body.
