  • Patent number: 11923720
    Abstract: An emergency light includes a lighting module configured for emitting lights, an input unit configured for receiving a power supply voltage from a home power supply, a normal driving module connected to the input unit to receive the power supply voltage and configured to output a first driving signal to drive the lighting module emit lights when the home power supply is normal; and an emergency control and battery module connected to the two input terminals and the lighting module. The emergency control and battery module is configured for detecting the alternating voltage of the input unit and a resistance value between the two input terminals to determine whether the home power supply failure occurs. When the home power supply failure occurs, the emergency control and battery module provides a second driving signal to drive the lighting module emit lights.

  • Patent number: 11832368
    Abstract: A device may detect a power removal event, determine whether the power removal event is a local power removal event or a system power removal event, and perform state correction. For example, the device may receive an indication of a state change event turning on the lighting device. The indication may be received from a sensor. For example, the sensor may include a photosensing circuit (e.g., capable of detecting light emission from the lighting device) or the sensor may include a live voltage sensor (e.g., capable of detecting a change in current driven to the lighting device). The device may then determine whether the power removal event is a system power removal event or a local power removal event. If the device determines that the power removal event is a system power removal event, the device may perform state correction (e.g., setting the lighting device to its state prior to the power removal event).

  • Patent number: 10637732
    Abstract: A system comprises a plurality of components connected in a wireless network and at least one unconnected (new) component available to join the network. The components are divided amongst a plurality of luminaires, each comprising a respective subgroup of the components including at least one lamp, and each subgroup has a respective subgroup ID. At least a first one of these components is configured to automatically detect whether a previously-present one of the components from the same respective subgroup as the first component is missing from the network. In response to detecting that the previously-present component is missing, the first component automatically causes the new component to be joined to the wireless network, and to be assigned to the same subgroup as the first component under the same subgroup ID.

  • Patent number: 10608531
    Abstract: A precision control device generally includes a current-limiting resistance, a voltage control unit, and a feedback voltage regulation unit. The current-limiting resistance has a grounded end and is serially connected to a DC load. The voltage control unit includes a microprocessor, an ADC, and a DAC. The feedback voltage regulation unit includes at least one operational amplifier and a transistor having a control input, a collector, and an emitter. The transistor is configured to operate at an unsaturated region, wherein the control input thereof receives a signal sent from an output terminal of the operational amplifier. The precision control device enables a power supply to smoothly adjust a predetermined output voltage set value for the DC load in response to a deviation of a voltage applied to the DC load. As such, the current flowing through the DC load and the current-limiting resistance can be regulated at a stable level.

  • Patent number: 10517154
    Abstract: A load control device (e.g., an LED driver) for controlling the intensity of a lighting load (e.g., an LED light source) may provide a wide output range and flicker-free adjustment of the intensity of the lighting load. The load control device may comprise a load regulation circuit, a control circuit, and a filter circuit (e.g., a boxcar filter circuit) that operates in a different manner in dependence upon a target current. When the intensity of the lighting load is near a low-end intensity, the control circuit may adjust an operating frequency of the load regulation circuit in response to the target current, and may control the filter circuit to filter a current feedback signal during a filter window that repeats on periodic basis. When the intensity of the lighting load is near a high-end intensity, the control circuit may control the filter circuit to constantly filter the current feedback signal.
