    摘要： A scanning light source 10 includes a light source 110, and scans the output light of the light source 110 ahead of a lamp. A control apparatus 200 controls the lighting on/off state of the semiconductor light source in synchronization with the scanning operation of the scanning light source 10. The control apparatus 200 judges the presence or absence of an abnormal state with at least one from among (i) a timing immediately before switching from a lighting-on state to a lighting-off state and (ii) a timing immediately before switching from a lighting-off state to a lighting-on state as a judgment timing.

    摘要： A method (400) for analyzing output of lighting units (10) in a lighting system (100) includes the steps of: (i) simulating (430), based on data from a photometric database (310), the output of a lighting unit; (ii) receiving and storing (420), from a database (330) of historical information, historical observed data about the output of the lighting unit; (iii) receiving (450) observed data (36) about the output of the lighting unit; (iv) generating (440) a model of the lighting system based at least in part on the simulated output of the lighting unit and the historical observed data about the output of the lighting unit, wherein the model comprises localization information for the lighting unit; and (v) comparing (470) the received observed data about the output of the lighting unit to the generated model, wherein a fault is detected if the observed data varies from the generated model by a predetermined amount.

    摘要： An image sensor system includes an image sensor and a prediction part. The image sensor includes an illumination module and a processing part. The illumination module includes a light emitting part for emitting light and a nonvolatile memory. The processing part stores a first data and a second data in the memory. The first data includes an electric parameter value when the light emitting part is applied with a power and a cumulative power-on time obtained by accumulating a time when the light emitting part is applied with the power. The second data includes a value obtained by multiplying the electric parameter value when the light emitting part is applied with the power by the cumulative power-on time. The prediction part obtains the first data or the second data from the memory and predicts a lifetime of the light emitting part based on the first data or the second data.

    摘要： A lighting system (100; 120) comprises at least one lamp (10) and a processing unit (20) for estimating an end-of-life of the at least one lamp (10). The processing unit (20) is configured to receive a lamp burning time during which the at least one lamp is turned on and a forecasted temperature over a selected period of time at a location of the at least one lamp. The processing unit (20) is configured to estimate the end of life of the at least one lamp based on the lamp burning time and the forecasted temperature. By using the forecasted temperature, use of dedicated lamp sensors measuring internal parameters of the lamp usable for the end-of-life estimate may be avoided and the estimate may be simplified.
