It may thus comprise a clasp or fastener and a chain or cord that may pass through a perforation of the shell. The shell 137 may comprise an aperture or cavity on where the light source 135 may be attached.
[0031] FIG. 2 schematically illustrates a luminaire according to another example. Luminaire 200 comprises a charging base 205 and a plurality of rechargeable illuminating personal ornaments 210 coupled to the charging base 205. The charging base 205 comprises a base platform 215 and a post 220. The post 220 may be integrated on one edge with the base platform 215 or may be attachable (e.g. screwable) on one edge to the base platform 215. The post 220 may comprise branches 222. Each branch 222 may be integrated on one edge with the post 220 or may be attachable (e.g. screwable) on one edge to the post 220. The other edge of the branch 222 may comprise a power connector 225. The base platform 215 may provide stability to the luminaire and may also host a power cable reaching all the way to the power connectors 225 to provide power to the rechargeable illuminating personal ornaments 210 when the rechargeable illuminating personal ornaments 210 are on the charging base 205. The rechargeable illuminating personal ornaments 210 may comprise a matching power connector 230 to match the power connector 225 of the branches. Furthermore, each rechargeable illuminating personal ornament 210 may comprise a shell 232, a light source 235 attached to the shell 230, and a rechargeable power source 235, located in the shell and connected to the light source 235 and to the matching power connector 230. The shell may comprise further elements such as pins, clips, chain holders etc. In the example of FIG. 2, the rechargeable illuminating personal ornaments 210 are in the form of spherical earrings. They may thus comprise a pin or clasp that may be attached to the shell 232 and may be suitable to be worn on an ear. The shell 232 may comprise an aperture or cavity on where the light source 235 may be attached.
[0032] FIG. 3 schematically illustrates a rechargeable illuminating personal ornament according to an example. The rechargeable illuminating personal ornament 310 may comprise a shell 332, a light source 335 (e.g. a LED) attached to the shell 332, and a rechargeable power source 333 (e.g. a battery), located in the shell 332 and connected to the light source 335 and to a power connector 337. In the example of FIG. 3, the rechargeable illuminating personal ornament 310 is in the form of a spherical earring.
[0033] FIG. 4 schematically illustrates a rechargeable illuminating personal ornament according to another example. The rechargeable illuminating personal ornament 410 may comprise a shell 432 and a light source 435 (e.g. a LED) attached to the shell 432. In the example of FIG. 4, the rechargeable illuminating personal ornament 410 is in the form of a hexahedral pendant.
[0034] FIG. 5 schematically illustrates an electrical diagram of a rechargeable illuminating personal ornament according to an example. Personal ornament 500 may comprise a pair of connection pins 505. One end of the pins 505 may be connectable to a power source, e.g. a DC power supply. The other end of the pins 505 may be connected to a voltage rectifier 510. The voltage rectifier may set the polarity of the voltage. Thus the pins 505 may be coupled to the power supply without worrying about the polarity. The personal ornament 500 may further comprise a charger/power supply block 515. The charger 515 may be coupled to the rectifier 510 and to a battery 520, e.g. a Polymer Lithium Ion battery, and may charge the battery as long as the ornament is attached to the base or it may supply power to the ornament through the battery when it is disconnected from the base. A microcontroller (μCU) 525 may be coupled to the charger. A serial I/O interface 530 may be coupled to the μCU 525 and to the output of the rectifier 510. When the ornament is connected to a power source then the block 515 may act as a charger to charge the battery 520. When the ornament is disconnected from the power source then the block 515 may act as a power supply to the μCU 525, the μCU 525 receiving power from the battery 520. The μCU 525 may provide power (either from the power source or from the battery 520) to a LED driver 535 of the ornament 500 and the LED driver 535 may power a LED 540 of the ornament 500.
[0035] FIG. 6 schematically illustrates an electrical diagram of a charging base for rechargeable illuminating personal ornaments according to an example. The charging base 600 may comprise a power supply 605. The power supply 605 may be connectable to a mains connector. The power supply 605 may provide power to a Bus Power supply 610 and to a μCU 615 of the charging base 600. The Bus Power supply may provide power to ornament connection pin pairs 650 coupled along a power bus 620. The μCU 615 may be coupled to a Human Machine Interface (HMI) button switch 630 to control power supplied to the ornament pin pairs (and thus control brightness of any ornaments coupled to the pin pairs 650). A Serial I/O interface 625 may be coupled between the μCU 615 and the power bus 620. The HMI button switch 630 may be coupled to the μCU and may be Normally Open (N.O). The input may be encoded and asynchronously—serially sent to the Serial I/O interface 625. The Serial I/O interface 625 is essentially a transistor connected to the jewelry feed bus with a common emitter—open collector configuration. The transistor may be connected to a Pull-up resistor located at the bus power supply. The bus power supply generates the voltage that supplies the jewelry (i.e. the ornaments) for charging and provides them with voltage through the pullup resistor to make the communication between the jewels and the base, and vice versa, possible.
[0036] FIG. 7 schematically illustrates an electrical diagram of a wireless charging base for rechargeable illuminating personal ornaments according to an example. The charging base 700 may comprise a power supply 705. The power supply 605 may be connectable to a mains power source, e.g. a 100-240V AC mains power source. The power supply 705 may provide power to a high frequency power generator 710, to a μCU 715, to a serial I/O interface (modulator) 720 and to buffers/demodulator amplifier blocks 730 of the charging base 700. The buffers/demodulator amplifier blocks 730 may be coupled to induction coils 735. Any ornaments to be charged may comprise respective induction coils and may be charged through a wireless induction charging using the respective induction coils. The μCU 715 may be coupled to an HMI button 730 to control power supplied to the buffers/demodulator amplifier blocks 730 (and thus control brightness of any ornaments inductively coupled to the induction coils 735). The serial I/O interface (modulator) 725 may be an RF transistor in a common emitter open collector configuration and may be coupled to the generator 710 through a pull-up resistor. The voltage-signal may be provided to the buffers/demodulator amplifier blocks 730. Each block 730 may correspond to an ornament position on the base. Each of the blocks may also comprise a transistor in an open collector configuration to allow the transmission of data from the ornaments to the base. Each induction coil pair (one from the base and one from the ornament) may function as a power supply of each ornament.
[0037] FIG. 8 schematically illustrates an electrical diagram of a wirelessly rechargeable illuminating personal ornament according to an example. Personal ornament 800 may comprise an induction coil 805. The induction coil 805 may be inductively connectable to an induction coil of the base, e.g. induction coil 735 of FIG. 7. The personal ornament 800 may further comprise a charger/power supply block 815. The charger may be coupled to the induction coil 805 and to a battery 820. A microcontroller (μCU) 825 may be coupled to the charger 815. A serial I/O interface 830 may be coupled to the μCU 825 and to the output of the induction coil 805. When the ornament is inductively coupled to induction coil 730 of the base, then the block 815 may act as a charger to charge the battery 820. When the ornament is uncoupled from the induction coil 730 of the base then the block 815 may act as a power supply to the μCU 825 receiving power from the battery 820. The μCU 825 may provide power (either from the power source or from the battery 820) to a LED driver 835 of the ornament 800 and the LED driver 835 may power a LED 840 of the ornament 800.
