摘要： This disclosure relates to a method of controlling light-emitting devices and a device thereof. The method includes: receiving broadcast signals broadcasted by light-emitting devices; obtaining a lighting video collected during lighting state switching of a light-emitting device; performing lighting state identification based on the lighting video, and determining a second lighting switching instruction message for switching the lighting state of each light-emitting device in the lighting video; matching the first lighting switching instruction message indicated by the broadcast signal with the second lighting switching instruction message corresponding to each light-emitting device in the lighting video to determine a broadcast signal corresponding to each light-emitting device in the lighting video; determining a network address of each light-emitting device in the lighting video based on the determined broadcast signal corresponding to each light-emitting device in the lighting video; and, controlling a corresponding light-emitting device.

摘要： Die Erfindung betrifft ein Verfahren zur Klassifizierung von mittels einer Partikeldetektionseinheit (200) detektierten Partikeln, welche Partikeldetektionseinheit (200) einen Lichtsender (210) zum Aussenden von Licht und einen Lichtempfänger (220) zum Erfassen von zumindest einem Teil des ausgesendeten Lichts aufweist, wobei der Lichtsender (210) und der Lichtempfänger (220) einen Detektionsbereich (DB) definierend zueinander ausgerichtet sind. In dem Verfahren werden innerhalb des Detektionsbereichs (DB) detektierte Partikel mittels Spektralanalyse klassifiziert, wobei
- mindestens ein erstes Lichtintensitätssignal (I1) und ein zweites Lichtintensitätssignal (I2), welche auf von dem Lichtempfänger (220) erfasstem Licht einer ersten charakteristischen Wellenlänge (λ1) und einer von der ersten charakteristischen Wellenlänge (λ1) abweichenden zweiten charakteristischen Wellenlänge (λ2) basieren, ermittelt werden,
- ein weiteres, ein Referenz-Lichtintensitätssignal (I0) ermittelt wird, welches auf von dem Lichtempfänger (220) erfasstem Licht einer charakteristischen Referenz-Wellenlänge (λ0) basiert, die von der ersten und der zweiten charakteristischen Wellenlänge (λ1, λ2) abweicht,
- das mindestens erste und zweite Lichtintensitätssignal (I1, I2), jeweils in Relation, insbesondere ins Verhältnis zu dem Referenz-Lichtintensitätssignal (I0) gesetzt wird,
- die so erhaltenen Relationswerte (I1/I0, I2/I0) in eine Klassifizierungskarte (130) eingeordnet werden, und
- anhand der Einordnung innerhalb der Klassifizierungskarte (130) eine Zuordnung der detektierten Partikel zu einer definierten Partikelklasse (S1, S2, S3) erfolgt.

摘要： A lighting device having intelligent predicting function is provided, which includes a driving module, a light source and an intelligent predicting control module. The light source is connected to the driving module. The intelligent predicting control module is connected to the driving module and communicates with an intelligent predicting sensing device disposed at a position away from the intelligent predicting control module. The intelligent predicting sensing device detects a moving object to generate a first sensing signal and transmits the first sensing signal to the intelligent predicting control module, such that the intelligent predicting control module turns on the light source via the driving module.

摘要： A lighting controller comprises a lighting driver and a control unit for controlling the lighting driver. The lighting driver has an analog dimming mode and a digital PWM dimming mode. A desired dimming level is converted to a combination of a first analog drive level with a first duty cycle and a second analog drive level, different to the first analog drive level, with a second duty cycle. A final drive signal is based on the combination. By using PWM control to alternate between two non-zero analog levels whenever possible, the perception of flicker is reduced and improved dimming ratios can be established.

摘要： Optical systems for linear lighting, particularly linear lighting that is installed in a channel, are disclosed, as are light fixtures that use these optical systems. The optical systems have multiple optical elements, usually a first lens adapted to be positioned close to a strip of linear lighting installed in a channel, and a second lens adapted to be positioned farther from the strip of linear lighting. In some cases, the first optical element may be a diffuser. The two optical elements are optically aligned with one another such that light from the first optical element reaches the second optical element. The multiple optical elements may be adapted to physically support one another, and to engage with structure provided by the channel for securing a cover. Some optical systems may be adapted to compensate for variations in the color or intensity of the emitted light.
