Abstract

A LED-light includes a light frame and a light base connected with a first end of the light frame. The light base is of substantially cylindrical design and is provided with an Edison thread which extends concentrically around a central axis of the light base. Further, the LED-light includes a number of LEDs mounted in or on the light frame and at least one photovoltaic cell mounted in or on the light frame. Connected with the light frame or the light base is a battery, as well as an electric circuit. Connected to the electric circuit are the number of LEDs, the battery and the at least one photovoltaic cell.

Claims

1. A LED-light comprising:

a light frame;

a light base connected with a first end of the light frame, wherein the light base is of substantially cylindrical design and has a central axis, wherein the light base is provided with an Edison thread extending concentrically around the central axis, or wherein the light base is provided with a bayonet fastener;

a number of LEDs mounted in or on the light frame;

at least one photovoltaic cell mounted in or on the light frame;

a battery connected with the light frame or the light base;

an electric circuit connected with the light frame or the light base and to which the number of LEDs, the battery and the at least one photovoltaic cell are connected,

wherein the light frame at a first end thereof is detachably connected with the light base, wherein the light frame is a single injection-molded piece further provided with a battery chamber, wherein the battery chamber at the first end of the light frame is provided with a battery chamber opening via which a battery is insertable into the battery chamber, wherein the battery chamber opening is closable with the light base detachably connected with the light frame, wherein the light frame has a second end remote from the light base, wherein the LED-light further comprises a light-transmitting light top connected with the second end of the light frame, wherein the light top has a substantially spherical segment-shaped configuration, wherein the LED-light is provided with a substantially plate-shaped support element included in the light frame and provided with at least one opening, wherein the plate-shaped support element has two opposite main surfaces, a first of which faces the light base and a second of which faces the light top, wherein the electric circuit is mounted on the plate-shaped support element on the first side of the support element, wherein the LEDs mounted on the electric circuit extend through said associated at least one opening in the support element, such that the light emitted in use by the LEDs falls directly on the inner side of the light top, and wherein the at least one photovoltaic cell is mounted on the second side, facing the light top, of the plate-shaped support element, such that outside light falls via the light-transmitting light top onto the at least one photovoltaic cell.

2. The LED-light according to claim 1, wherein on the light base a contact is provided, the contact being electrically conductive and being in communication with the electric circuit, wherein the electric circuit is configured to place the LEDs into connection with the battery, so that the LEDs burn when there is a voltage on the contact, and wherein the electric circuit is configured to break the connection between the battery and the LEDs when there is no voltage on the contact, so that the LEDs do not burn.

3. The LED-light according to claim 1, wherein the Edison thread is of the type E27 according to IEC 60061-1 (7004-21) or DIN 49620 or is of the type E14 according to IEC 60061 (7004-23) or DIN 49615.

4. The LED-light according to claim 1, wherein the bayonet fastener is of the type B15d according to IEC 60061-1 (7704-11) or DIN 49721 or is of the type B22d according to IEC 60061-1 (7004-10).

5. The LED-light according to claim 1, wherein the light base is manufactured from plastic.

6. The LED-light according to claim 1, further comprising a wireless receiver configured for wireless communication with a transmitter, wherein the wireless receiver is part of the electric circuit, and wherein the electric circuit is configured to switch the LEDs on and off depending on a signal delivered by the wireless receiver.

7. The LED-light according to claim 1, further comprising a switch arranged on the light frame or the light base, the switch being a part of the electric circuit, wherein the electric circuit is configured to switch the LEDs on and off depending on the position of the switch.

8. The LED-light according to claim 1, wherein the light base is provided with electrically conductive contacts, wherein the electric circuit is configured to place the battery into connection with the contacts when the amount of stored energy in the battery is below a first threshold value, and wherein the electric circuit is configured to break the electrical connection between the battery and the contacts when the amount of stored energy in the battery is above a second threshold value.

9. The LED-light according to claim 1, wherein the battery is removable.

10. The LED-light according to claim 1, provided with an adapter terminal arranged for connection of an external supply adapter for the purpose of charging the battery.

11. The LED-light according to claim 1, wherein the at least one photovoltaic cell is in a plane extending perpendicular to the central axis and wherein a light-sensitive surface of the photovoltaic cell is remote from the light base, wherein the LEDs are so disposed as to radiate at least in the direction of the central axis, more specifically such that the radiation direction points away from the light base.

12. The LED-light according to claim 1, wherein the light base is further provided with a contact plate connected with the light base and forming the closure of the battery chamber and against which a battery placed in the battery chamber abuts by one end so as to form an electrical contact, wherein the contact plate is connected via an electrically conductive lead with the electric circuit for energizing the electric circuit by means of the battery and for charging the battery by means of the at least one photovoltaic cell.

13. The LED-light according to claim 12, wherein between the contact plate and a battery placed in the battery chamber an electrically insulating pull tab is provided, wherein the pull tab, prior to the LED-light being put into use, breaks the electrical contact between the battery and the contact plate, wherein the pull tab is engageable from an outside of the LED-light to enable it to be pulled away for establishing electrical contact between the battery and the contact plate.

14. The LED-light according to claim 13, wherein the electric circuit is provided with an on/off switch extending through an associated opening in the plate-shaped support element and being accessible when the light top is detached from the light frame.
