Patent ID: 8525415

Claim:
A vehicular LED lamp monitoring/controlling system comprising: a vehicular LED lamp including a lamp base, with the lamp base including a mounting seat and a heat pipe, with the mounting seat including a plurality of annularly arranged faces each having a groove, with a carrier plate mounted in each groove, with each carrier plate including a first LED and a second LED, with the mounting seat including an end having a receptacle, with the heat pipe including an end received in the receptacle; a malfunction detecting unit electrically and separately connected to the first and second LEDs on each carrier plate, with the malfunction detecting unit detecting whether the first and second LEDs on each carrier plate operate normally after the first and second LEDs on each carrier plate are activated; a selection/control unit electrically and separately connected to the first and second LEDs on each carrier plate, with the selection/control unit separately controlling activation of the first and second LEDs on each carrier plate, with the selection/control unit electrically connected to the malfunction detecting unit, with the second LED on at least one of the carrier plates activated by the selection/control unit when the malfunction detecting unit detects abnormal function of the first LED on a corresponding carrier plate; a temperature monitoring unit electrically connected to the selection/control unit or the malfunction detecting unit, with the temperature monitoring unit detecting a working temperature of the vehicular LED lamp, with the temperature monitoring unit setting a safe temperature; a heat dissipating unit electrically connected to the selection/control unit; a power control unit electrically connected to the selection/control unit, with the power control unit sending a control signal to the selection/control unit to control luminance of each of the first and second LEDs on each carrier plate; and a vehicle speed monitoring unit electrically connected to the power control unit, with the vehicle speed monitoring unit reading a speed of a vehicle on which the vehicular LED lamp is mounted, wherein when the working temperature of the vehicular LED lamp detected by the temperature monitoring unit is higher than or equal to the safe temperature, the temperature monitoring unit sends a signal to the selection/control unit to drive the heat dissipating unit, proceeding heat dissipation of the vehicular LED lamp, wherein when the speed of the vehicle is not equal to zero, the vehicle speed monitoring unit controls the power control unit to send the control signal to the selection/control unit to control the first or second LED on each carrier plate to provide normal luminance, wherein when the speed of the vehicle is equal to zero, the vehicle speed monitoring unit sends a signal indicative that the vehicle is not moving to the power control unit, controlling the first or second LED to provide reduced luminance lower than the normal luminance.
