    Abstract: An LED lamp is placed in service on an automotive vehicle to enhance nighttime visual ability or anywhere where increased lighting is needed. The LED lamp utilizes a multi-stage power and control design, where the LED drive current is managed by an LED constant current controller that is coupled to a microprocessor that commands the intensity value of an LED array. The microprocessor manages the light intensity of the LED array using well known pulse-width modulation control methods. The microprocessor measures the voltage of the DC power source and to detect when DC power is removed. Once this detection has occurred, the microprocessor signals the LED current controller to change the current operational mode being delivered to the LED array to the next available operational mode, or alternatively, to the next appropriate operational mode to be used as determined by software stored within the microprocessor.

    Abstract: A daytime running lamp (DRL) controller for controlling power to a light source of a vehicle includes a switch, an engine starting-up detector and a switch control circuit. The switch is coupled to the light source. The engine starting-up detector is coupled to the switch, and generates a trigger signal if the engine is starting up. The switch control circuit is coupled to the switch and the engine starting-up detector, and includes a controller. The controller generates a first control signal to switch on the switch to power on the light source responsive to the trigger signal, and keeps outputting the first control signal if a holding signal is generated within a first time period after the trigger signal is received. The first time period is a time period during which the controller is reset after receiving the trigger signal.

  • Patent number: 8330374
    Abstract: A vehicle-mounted load controller is characterized by including: a power terminal connected to a power line through a fuse; load connecting portions to which loads having vehicle-mounted light sources are connected; switches which are provided corresponding to the load connecting portions and which control states of power supply from the power line connected to the power terminal to the light sources connected to the load connecting portions; and a control unit which controls the switches in response to inputted control signals. The vehicle-mounted load controller is characterized in that the multiple load connecting portions to which the multiple light sources for different uses are respectively connected are electrically connected to the power terminal, and that each of the switches stops the supply of power from the power line to the light source connected to the corresponding load connecting portion when the magnitude of current flowing through the light source reaches or exceeds a predetermined value.

  • Patent number: 8330385
    Abstract: A light bar system for a vehicle compartment includes a circuit board having a plurality of capacitive-type, user-activated switches, an electrical power source coupled to the circuit board, a light emitting diode (LED) coupled to the circuit board, and a light bar affixed to the circuit board. The user-activated switches are coupled to a vehicle accessory to control the level of operation of the vehicle accessory. The most recently actuated one of the user-actuated switches is detected by the circuit board and the circuit board provides a pulse width modulated (PWM) signal to the LED with a duty cycle of the PWM signal based on the most recently actuated switch. A higher duty cycle PWM signal corresponds to a higher setting of the accessory.

  • Patent number: 8278826
    Abstract: A multimode controller for LED light sources, especially sources in warning lights, such as light bars, provides for a temporary increase in brightness from the LEDs by providing a burst mode, in addition to a flashing mode and a continuous mode. The modes are carried out by programming a microprocessor which receives signals from control switches, which may be pressed and released. The programming precludes the burst mode to continue for longer than a predetermined time thereby ensuring that the power does not exceed the LEDs damage threshold characteristic. The controller thereby provides for temporary bursting to make visible the region in front of or around an emergency vehicle for a short period of time without the need for light sources dedicated solely to the high intensity brightness mode of operation of a warning light system.
