## Abstract The present invention relates to an on-board illuminating device comprising an illuminating unit and a control unit, wherein the control unit transmits a first control signal to the illuminating unit according to an event inside a vehicle (10) characterizing a preparation action for getting out of the vehicle, and the illuminating unit enters an illuminating state in accordance with the first control signal. ## Claims ### Claim 1 An on-board illuminating device comprising an illuminating unit and a control unit, wherein the control unit transmits a first control signal to the illuminating unit according to an event inside a vehicle characterizing a preparation action for getting out of the vehicle, and the illuminating unit enters an illuminating state in accordance with the first control signal. ### Claim 2 (depends on 1) The illuminating device according to claim 1, wherein the illuminating unit is mounted outside the vehicle and includes a receiver for receiving the first control signal. ### Claim 3 (depends on 1) The illuminating device according to claim 1, wherein the control unit is mounted inside the vehicle, the illuminating unit and the control unit are in wireless signal connection with each other. ### Claim 4 (depends on 1) The illuminating device according to claim 1, wherein emergent light of the control unit forms a predetermined warning pattern on the ground. ### Claim 5 (depends on 4) The illuminating device according to claim 4, wherein the control unit further includes a timer which transmits a second control signal to the illuminating unit at a predetermined time after the illuminating unit enters the illuminating state, and the illuminating unit enters a non-illuminating state in accordance with the second control signal. ### Claim 6 (depends on 5) The illuminating device according to claim 5, wherein the first control signal and the second control signal are wireless signals. ### Claim 7 (depends on 4) The illuminating device according to claim 4, wherein the illuminating unit further includes a timer, wherein timer switches the illuminating unit into the non-illuminating state at a predetermined time after the illuminating unit enters the illuminating state. ### Claim 8 (depends on 5) The illuminating device according to claim 5, wherein the control unit further includes a detecting device and the control unit sends the first control signal, when the detecting device detects the event inside the vehicle characterizing a preparation action for getting out of the vehicle. ### Claim 9 (depends on 8) The illuminating device according to claim 8, wherein the event inside the vehicle characterizing a preparation action for getting out of the vehicle is an action of person within the vehicle preparing to exit. ### Claim 10 (depends on 9) The illuminating device according to claim 9, wherein the control unit is additionally mounted on seat belts of the vehicle, and the control unit identifies the action of releasing the seat belt from a fastened state as the action of the person within the vehicle preparing to exit. ### Claim 11 (depends on 10) The illuminating device according to claim 10, wherein the control unit further includes a circuit board and a projector, the circuit board, the projector and the detecting device being in electrical and signal connection with each other. ### Claim 12 (depends on 11) The illuminating device according to claim 11, wherein the control unit is configured to be flexible and in strip. ### Claim 13 (depends on 12) The illuminating device according to claim 12, wherein the detecting device is configured as pressure sensor, and the detecting device is at least partially fixed in the buckle region of the seat belt. ### Claim 14 (depends on 12) The illuminating device according to claim 12, wherein the detecting device is configured as magnetic detector and the control unit itself forms a closed annular device, the detecting device surrounding a socket receiving the metal plug of the seat belt. ### Claim 15 (depends on 14) The illuminating device according to claim 14, wherein the control unit further includes two free ends respectively configured as a USB plug and a corresponding port, the USB plug is to be plugged into the corresponding port and a closed magnetic circuit can be produced within the control unit. ### Claim 16 (depends on 15) The illuminating device according to claim 15, wherein the USB plug acts as charging port for connection of the control unit with an external power source, if the event inside the vehicle characterizing a preparation action for getting out of the vehicle does not occur. ### Claim 17 (depends on 8) The illuminating device according to claim 8, wherein the event inside the vehicle characterizing a preparation action for getting out of the vehicle is the flipping of the taximeter board of the vehicle. ### Claim 18 (depends on 5) The illuminating device according to claim 5, wherein the illuminating unit is mounted below the vehicle and a light emergent opening of the illuminating unit is directed towards a predetermined illuminated area. ### Claim 19 (depends on 18) The illuminating device according to claim 18, wherein the illuminating unit is mounted below a door of the vehicle and the predetermined illuminated area is a region passed by the door during the opening process. ### Claim 20 (depends on 19) The illuminating device according to claim 19, wherein the illuminating unit further includes a housing with the light emergent opening, a light emitting module and a power line, wherein the light emitting module positioned in the housing and the receiver are in signal connection with each other, and the power line passes through the housing and electrically connects the light emitting module with the power source of the vehicle. ### Claim 21 (depends on 20) The illuminating device according to claim 20, wherein the illuminating unit further includes a filter grid mounted on the light emergent opening, and emergent light of the light emitting module passes through the filter grid and forms a predetermined pattern in the predetermined illuminated area.
