## Abstract

An LED light includes a housing. The housing includes a bulb shaped upper end extending from a nonconductive threaded lower end. The interior of the housing has a charging port extending from the threaded lower end. A battery enclosure is electrically coupled to the charging port. A first PCB board is positioned within upper end. A power circuit is formed on the first PCB board and is electrically coupled to the battery enclosure to provide DC power to the first PCB board. A second PCB board is positioned within upper end of the housing; stacked over the first PCB board. The first PCB board is electrically connected to the second PCB board. A plurality of LEDs are arranged on the second PCB board to direct light from a distal end of the upper end of the housing in response to receiving a control signal and power from the second PCB board.

## Claims

### Claim 1

An LED light comprises:
a housing; the housing having a bulb shape;
a nonconductive threaded base configured to be received in a conventional light bulb socket, the housing being affixed to and extending from the base;
a charging slot formed in the threaded base;
a port in communication with the charging slot and extending within the base towards the housing;
a battery enclosure configured for receiving one or more batteries, the battery enclosure being disposed within the housing, and the battery enclosure being electrically coupled to the charging port;
a first PCB board disposed within the housing; a power circuit being formed on the first PCB board and electrically coupled to the battery enclosure to provide DC power to the first PCB board;
a second PCB board is positioned within the housing, supported by the first PCB board and stacked over the first PCB board; the power circuit being electrically connected to the second PCB board; and
a plurality of LEDs arranged on the second PCB board to direct light from an end distal from the base in response to receiving a control signal and power from the second PCB board.

### Claim 2 (depends on 1)

The LED light of claim 1, wherein the first PCB board is disposed in parallel with the second PCB board.

### Claim 3 (depends on 1)

The LED light of claim 1, further comprising control circuitry disposed on the second PCB board and electrically connected between the power circuit and the LEDS for controlling operation of the LEDs.

### Claim 4 (depends on 1)

The LED light of claim 1, wherein the battery enclosure, the power circuit, the control circuit and the plurality of LEDs form a circuit, and further comprising a switch disposed along the circuit for switching the plurality of LEDs between an OFF state and an ON state.

### Claim 5 (depends on 4)

The LED light of claim 4, wherein the switch is mounted on an exterior surface of the housing.

### Claim 6 (depends on 1)

The LED light of claim 1, wherein the housing includes a lower housing mounted on the base, and an upper housing disposed on the lower housing.

### Claim 7 (depends on 6)

The LED light of claim 6, further comprising a diffuser band for securing the lower housing to the upper housing.

### Claim 8 (depends on 6)

The LED light of claim 6, wherein the upper housing is selectively removeable from the lower housing.

### Claim 9 (depends on 6)

The LED light of claim 6, wherein the upper housing is a light diffuser.

### Claim 10 (depends on 1)

The LED light of claim 1, wherein the plurality of LEDS is disposed about a perimeter of the second PCB board.
