摘要:
A divider for a workspace comprises at least partially transparent panel and at least one controllable LED-based light source integrated with the panel and adapted to generate variable light within the panel. Transparency of the panel is variable between at least partially transparent and substantially opaque in dependence on the light generated by the at least one LED-based light source. At least one control interface is coupled to the at least one LED-based light source to facilitate control of the generation of variable light within the panel.
摘要:
Tube couleur aménagé pour contrôler le fonctionnement d'un canon réservé à une visualisation particulière, par exemple l'alarme en rouge, et qui de ce fait n'est normalement pas utilisé de façon autonome. Les aménagements comportent de préférence, à la fois un contrôle direct de continuité du circuit filament correspondant au moyen d'une sortie distincte (1-3) de ce filament, et un contrôle d'émission de la cathode (11) du canon réservé grâce à l'insertion d'une anode supplémentaire (12) destinée à former une diode avec cette cathode. Le contrôle (10) grâce aux connexions extérieures (9 - 15) créées peut s'exercer par détection de passage de courant. L'invention s'applique notamment à des tubes à masque perforé utilisés en avionique.
摘要:
The invention relates to a measuring circuit for detecting the amount of deposited electrode material on the wall of a lamp vessel of a discharge lamp by measuring the power of infrared radiation within a specific wavelength range, comprising a detector for generating an electrical signal constituting a measure for the power of the infrared light in said specific wavelength range. According to the invention the measuring is done in a time lapse starting after a predetermined time interval following the extinguishing of the discharge lamp. An increased accuracy of the measurement is thereby realized.
摘要:
Methods and apparatus for customization of a workspace, including lighting in the workspace. Multiple LED-based lighting units arranged in a personal workspace may be conveniently controlled by an occupant of the workspace to customize or personalize workspace lighting. Workspace customization, including lighting conditions, further is facilitated by various power distribution schemes to allow convenient access to power in the workspace for lighting units and other electronic devices. Workspace dividers, partitions and walls may be particularly configured to accommodate power distribution systems and various components of networked lighting systems in the workspace environment.
