摘要: A lighting arrangement has a lighting module with a sensor element in parallel with a light source arrangement between module terminals. A measuring system is provided for measuring, at the module terminals, a signal which is dependent on the sensor element when the light source arrangement is turned off. Thus, sensing is integrated into or connected to a lighting module, such as LED module.

摘要: A load control device for controlling the amount of power delivered to an electrical load is able to operate in a normal mode and a burst mode. The load control device may comprise a control circuit that activates an inverter circuit during active state periods and deactivates the inverter circuit during inactive state periods. The control circuit may operate in the normal mode to regulate an average magnitude of a load current conducted through the electrical load to be above a minimum rated current. The control circuit may operate in the burst mode to adjust the average magnitude of the load current to be below the minimum rated current. The control circuit may adjust the average magnitude of the load current by adjusting the length of the inactive state periods while holding the length of the active state periods constant.

摘要: A method of controlling a light driver includes determining, by a secondary controller of the light driver, an actual voltage drop across a regulator of the light driver; determining, by the secondary controller, a target voltage drop of the regulator; calculating, by the secondary controller, a theoretical input voltage of the regulator based on the target voltage drop and an output voltage of the regulator; determining, by the secondary controller, whether the theoretical input voltage is within a first range; and in response to determining that the theoretical input voltage is within the first range, generating, by the secondary controller, a first feedback signal for transmission to a primary controller of the light driver based on the target voltage drop and the actual voltage drop.

摘要: A method and apparatus for an adaptable vehicle light mount is provided. A recess created within an interior of a heat sink fin array of the vehicle light allows associated mounting hardware to be embedded within the recess. A physical offset between the vehicle light and the associated vehicle may therefore be minimized to provide a shallower mounting profile. A tube may be incorporated into the recess so as to allow one or more vehicle lights to be mounted to a single mount point on a vehicle where the tube and associated mounting hardware are incorporated and function as part of the heat reducing components of the vehicle light.

摘要: A device, system, and method configure a power supply of a powered device. The powered device includes a digital addressable lighting interface (DALI) connected to a load to be powered by a power source. The powered device includes an isolator. The powered device includes a controller positioned on a primary side of the isolator. The controller is configured to generate a first signal to select whether to provide power to the 5 DALI at a zero current value or a maximum current value. The controller is further configured to generate a second signal to provide power to the DALI at a selected current value between the zero current value and the maximum current value.

摘要: A voltage sensing circuit uses a voltage divider for providing a sense signal indicating the voltage across a circuit component. A current injector is used for injecting current to the sensing terminal. A sense signal is obtained with no current injection, to determine if a fault is present. The sensing terminal is coupled to the external circuit component via a voltage clamping component. A further sense signal is obtained in response to the injection of current. By comparing the sense signal in response to the injected current and a clamping voltage of the voltage clamping component, it can then be determined if the fault is caused by the circuit component or by the voltage divider.
