  • Patent number: 10278248
    Abstract: A light control and data interface module (LCDIM) is used to control an LED based illumination device. The LCDIM includes a transceiver that receives communication signals from one or more sensor modules. The signals may include an indication of an identity of the one or more sensor modules and elapsed time since a triggering event was detected. One or more processors are configured to receive the communication signal and to determine a delay time to trigger a lighting control response. The one or more processors are further configured to cause the transmission of a command signal to a power converter coupled to the LCDIM to implement the lighting control response.

  • Publication number: 20180209856
    Abstract: A light emitting diode (LED) based illumination module performs on-board diagnostics. For example, diagnostics may include estimating elapsed lifetime, degradation of phosphor, thermal failure, failure of LEDs, or LED current adjustment based on measured flux or temperature. The elapsed lifetime may be estimated by scaling accumulated elapsed time of operation by an acceleration factor derived from actual operating conditions, such as temperature, current and relative humidity. The degradation of phosphor may be estimated based on a measured response of the phosphor to pulsed light from the LEDs. A thermal failure may be diagnosed using a transient response of the module from a start up condition. The failure of LEDs may be diagnosed based on measured forward voltage. The current for LEDs may adjusted using measured flux values and current values and a desired ratio of flux values. Additionally, the LED current may be scaled based on a measured temperature.

  • Patent number: 9960848
    Abstract: Light Emitting Diode (LED) based illumination devices in a lighting communications network may be commissioned into a group with a mobile electronics device, such as a mobile phone, tablet computer, etc. The identities of a plurality of LED illumination devices are determined and a request is communicated to the identified LED based illumination devices to modulate emitted light for a period of time. The modulated light is detected by the mobile electronics device, which may then determine a group of the LED based illumination devices. For example, the detected intensity of the modulated light may be used to determine the group. In another example, the physical locations of the LED based illumination devices are determined by detecting a sequence of images (e.g., video) of the modulated light, and the group may be determined based on the locations of the LED based illumination devices.
