The present disclosure relates to rechargeable illuminating personal ornaments and luminaires employing said rechargeable illuminating personal ornaments

BACKGROUND

Luminaires are electrical devices used to create artificial light by use of an electric lamp.

Personal ornaments, also collectively called “jewellery”, consist of small decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants and bracelets.

Typically jewelry is stored in boxes and organizers. Such jewelry boxes and organisers are typically used for storage and display and occupy space with no further purpose in a home environment.

Some jewelry stands, holders or organisers exist for commercial display of jewelry. They typically have pockets or holes to receive pieces of jewelry, e.g. earrings, for decorative or demonstration purposes.

SUMMARY

New types of luminaires and personal ornaments are proposed. The personal ornaments may comprise a light source and a rechargeable power source and may be worn as illuminating ornaments. When not worn, they may be placed on a charging base to charge and at the same time form a luminaire.

In a first aspect, a luminaire is proposed. The luminaire comprises a charging base. The charging base comprises a power cable connectable to an external power source and a power connector. The luminaire further comprises a rechargeable illuminating personal ornament, connected to the charging base. The rechargeable illuminating personal ornament comprises a shell, a light source attached to the shell, a rechargeable power source, located in the shell and connected to the light source and a corresponding power connector, defining an opening in the shell and coupled to the rechargeable power source. The power connector of the charging base is coupled to the corresponding power connector of the rechargeable illuminating personal ornament.

The ornaments may be made of metal and of a semi-transparent polymer. The ornaments may be self-luminous using light emitting diodes (LEDs) of the Red-Green-Blue (RGB) type or of the Warm White (WW) or Cold White (CW) type. They may be rechargeable either through a wired or wireless connection. The base along with the ornaments may form a decorative lighting object. The base may comprise a controller. The controller may include a processor, a data storage coupled to the processor and an instruction set. The instruction set may cooperate with the processor and the data storage to control the luminance of the ornaments through an asynchronous serial communication. The base may comprise a button or a switch to switch on, switch off or control dimming of the ornaments ^' light while the ornaments are placed on the base and when the ornaments and base form a lighting ensemble. The base may be made of metal and may have additional decorative elements, e.g. of wood.

By using rechargeable illuminating personal ornaments as lighting elements of the luminaire, three functionalities may be achieved at the same time: First, a stand or holder for the ornaments is provided. Second, a recharging base for the illuminating ornaments is provided. And third, light may be produced while the ornaments are recharging.

In some examples, the luminaire may further comprise a power button. Thus the light effect during recharging may be selectable either on the charging base and/or on the rechargeable illuminating personal ornament. The term “power button” is used here to denote any type of switchable element that may alter a conductive state from on to off and vice verca.

In some examples, the charging base may comprise a plurality of charging points. Each charging point may comprise a power connector for receiving a corresponding power connector of a rechargeable illuminating personal ornament. Thus various rechargeable illuminating personal ornaments may be placed on the charging base to be recharged and/or serve as lighting elements of the luminaire. Furthermore, the luminaire may still provide light even if one or more of the rechargeable illuminating personal ornaments is off the charging base or simply switched off.

The base may be powered through a 100-240 Vac mains power source. Then, through a power supply, voltage may be provided to the individual electronic devices. The base may be linked to the jewelry through a pair of contacts for each jewel.

In some examples the rechargeable power source may comprise a rechargeable battery, such as a lithium-ion battery. This allows for multiple recharges of the battery with minimum loss in capacity. The rechargeable power source may also be replaceable.

The rechargeable illuminating personal ornament may comprise one or more of a brooch, a ring, a necklace, an earring, a pendant and a bracelet. The charging base may be either of a generic base, suitable to recharge any of the above ornaments provided that they have the same type of power connector, or may be specific to particular types or even models of ornaments. For example, the shape of the charging base may match a shape of the shell of the ornament allowing only ornaments with a matching shape to couple to the charging base.

The light source of the rechargeable illuminating personal ornaments may comprise one or more light emitting diodes (LEDs). LEDs provide light without heating up too much thus remaining comfortable when placed on personal ornaments that may be on or very near a person ^' s body part. However, other types of light sources may be used.

In some examples, the power connector may be a Universal Serial Bus (USB) connector. Thus a charging base may also serve for charging other devices. Furthermore, third party ornaments may also be used with the charging base. Furthermore, the ornaments may be recharged by common USB type rechargers even without the presence of the charging base. For that purpose the power connector may be a USB plug connector and the corresponding power connector may be a USB receptacle connector or vice versa. In other examples, the charging of the ornaments may be performed wirelessly, e.g. using induction coils.

In some examples, the luminaire may comprise a desk luminaire. As such, the luminaire may comprise a base to stand on a desk and a power cord to be connected to a wall outlet. The desk luminaire may thus be used as a common desk lamp when the ornaments are placed on the charging base and the luminaire is switched on.

In another aspect, a rechargeable illuminating personal ornament is disclosed. The rechargeable illuminating personal ornament may comprise a shell; a light source attached to the shell; a rechargeable power source, located in the shell and connected to the light source; and a power connector, defining an opening in the shell to receive power from a corresponding power connector of a charging base.

The ornaments may be connected to the base through a pair of contact pins. Polarity may not matter because the ornament may comprise a rectifier bridge through which the output polarity may be set. A charger block may be connected to a battery, e.g. a Polymer Lithium Ion battery, that 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.

The rechargeable illuminating personal ornament may comprise a brooch, a ring, a necklace, an earring, a pendant or a bracelet. Thus, the shell may accordingly comprise pins, clips, or any other attachment means for attaching to a part of the body, e.g. ear, nose, finger etc. or to a garment worn on the body of a user.

In yet another aspect, a charging base for a luminaire is disclosed. The charging base may comprise one or more charging stations for rechargeable illuminating personal ornaments. Each charging station may comprise a power connector to receive a corresponding power connector of a rechargeable illuminating personal ornament.

The shell may comprise further elements such as pins, clips, chain holders etc. In the example of Fig. 1A and 1 B, the rechargeable illuminating personal ornament 110 is in the form of a pendant. 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.

Figure 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.

Figure 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.

Figure 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.

Figure 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 (pCU) 525 may be coupled to the charger. A serial I/O interface 530 may be coupled to the pCU 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 pCU 525, the pCU 525 receiving power from the battery 520. The pCU 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.

Figure 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 pCU 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 pCU 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 pCU 615 and the power bus 620. The HMI button switch 630 may be coupled to the pCU 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.

Figure 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 pCU 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 pCU 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.

Figure 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 (pCU) 825 may be coupled to the charger 815. A serial I/O interface 830 may be coupled to the pCU 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 pCU 825 receiving power from the battery 820. The pCU 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.
