Abstract
A modulated passive optical lighting device includes a passive element, such as a window, a sun-room roof, or a skylight. The device also has an optical modulator associated with or incorporated in the device, to modulate light supplied to an interior space to carry data.
Claims16
A system, comprising:
- a passive lighting device, including:
- a passive optical element, that is at least substantially transmissive with respect to daylight, configured to receive daylight from outside a structure and allow passage of light to an interior of the structure;
- and
- an optical modulator associated with the passive optical element to modulate light passively supplied through the optical element for modulated emission into the interior of the structure;
- and
- logic/processor circuitry coupled to control the modulator to modulate data on the light emitted from the passive lighting device into the interior of the structure in a manner to minimize or prevent perception of the data modulation by an occupant in the interior of the structure.
3 more elements
A system, comprising:
- a luminaire and a passive daylighting device, each respective one of the luminaire and the daylighting device being configured to modulate light output thereof to carry a respective identification (ID) code that is unique at least within an interior space to be illuminated by the luminaire and the daylighting device;
- storage accessible to a processor of a mobile device;
- and
- a lookup table in the storage device mapping the ID codes of the luminaire and the daylighting device to information related to positions of the luminaire and the daylighting device.
1 more element
A portable handheld device, comprising:
- a light sensor;
- a processor coupled to the light sensor;
- a memory coupled to be accessible to the processor;
- and
- programming in the memory for execution by the processor to configure the portable handheld device to perform functions, including functions to:
- generate by the light sensor a signal responsive to modulated light received by the sensor from a passive lighting device;
- and
- process by the processor the signal generated by the light sensor to obtain information transported by the modulated light from a modulated passive lighting device.
5 more elements
A device, comprising:
- a network communication interface;
- a processor coupled to the network communication interface;
- storage coupled to be accessible to the processor;
- a lighting device identification database in the storage, the database containing records for lighting devices transmitting modulated light representing respective (ID) codes of the lighting devices, each record correlating the ID code of a respective lighting device to location-related information, one of the lighting device records being for a modulated passive lighting device;
- and
- programming in the storage, wherein execution of the programming configures the processor to:
- determine an ID code of the passive lighting device obtained from modulated light transmitted by the passive lighting device;
- based on the ID code of the passive lighting device, retrieve the record for the passive lighting device;
- and
- process location-related information from the record for the passive lighting device.
7 more elements
A system, comprising:
- a passive lighting device, including:
- a passive optical element, that is at least substantially transmissive with respect to daylight, configured to receive natural light from outside a structure and allow passage of light to a predetermined area;
- and
- an optical modulator associated with the passive optical element to modulate the light passively supplied through the optical element for modulated emission to the predetermined area;
- and
- logic/processor circuitry coupled to control the modulator to modulate data on the light emitted from the passive lighting device to the predetermined area in a manner to minimize or prevent perception of the data modulation by an occupant in the predetermined area.
