Abstract

A USB-chargeable emergency light structure has a light base, a charging/outputting circuit unit, a connector and a charging socket. The light base defines an accommodating space therein for receiving the charging/outputting circuit unit that has a plurality of light sources. The connector partially protrudes from the base and is electrically connected to the charging/outputting circuit unit. The connector is a USB connector. The charging socket is mounted on the light base and electrically connected to the charging/outputting circuit unit. The lighting structure thereby constructed can be used as an emergency light, a night light, a flashlight or a charging device.

Claims

1. A universal serial bus (USB)-chargeable emergency light structure, comprising:

a light base, defining an accommodating space therein;

a charging/outputting circuit unit, mounted inside the accommodating space and having a plurality of light sources;

a connector, electrically connected to the charging/outputting circuit unit, wherein the connector partially protrudes from the base and is a USB connector; and

a charging socket, mounted on the light base and electrically connected to the charging/outputting circuit unit.

2. The lighting structure of claim 1, wherein the light base includes a first base portion and a second base portion that are connected to each other by snap fitting, clasping screwing, or ultrasonic welding to define the accommodating space.

3. The lighting structure of claim 1, wherein a plurality of light holes is formed on the light base with the light sources corresponding to the light holes.

4. The lighting structure of claim 1, wherein the charging/outputting circuit unit includes a circuit board and a plurality of electronic components, and the lighting sources are mounted on the circuit board.

5. The lighting structure of claim 1, wherein a power indicator lighting and a charging status indicator lighting are further mounted on the circuit board, and the circuit board has a plurality of light holes respectively corresponding to the power indicator lighting and the charging status indicator lighting.

6. The lighting structure of claim 1, wherein the charging/outputting circuit unit is further provided with a switch.

7. The lighting structure of claim 1, wherein the charging/outputting circuit unit is further provided with a dimmer by which the light emitted from the light sources is adjusted as desired.

8. The lighting structure of claim 1, wherein the connector is pivotally connected to the charging/outputting circuit unit in a foldable way.

9. The lighting structure of claim 1, wherein the charging socket has an opening for receiving a chargeable battery, a guiding piece being respectively mounted on two opposite inner sides of the opening to connect electrically the charging/outputting circuit unit with the charging socket, and a cover being further pivotally mounted on the charging socket to cover the opening.

10. The lighting structure of claim 1, wherein a winding reel around which a plurality of wires are wound is placed inside the light base, the wires being either wound up in the light base or partially pulled out from the light base, and the connector being connected to one tip of the wires.

11. The lighting structure of claim 1, wherein the connector is inserted in an electric socket for domestic electric distribution via an adapter.
