## Abstract

A lighting device, comprising a housing, a control circuit and a solid-state light emitting unit, is disclosed. The housing includes a receiving space, and the material of the housing is wax. The control circuit is sealed in the receiving space and provides a control signal. The solid-state light emitting unit is sealed in the receiving space and receives the control signal to provide a light.

## Claims

### Claim 1

A lighting device, comprising:
a housing, having a receiving space, and a material of the housing being wax;
a control circuit, being sealed in the receiving space and providing a control signal; and
a solid-state light emitting unit, being sealed in the receiving space and receiving the control signal to provide a light.

### Claim 2 (depends on 1)

The lighting device as claimed in claim 1, wherein the housing further has a main lighting surface, and a shortest distance between the receiving space and the main lighting surface is less than 3 inches.

### Claim 3 (depends on 1)

The lighting device as claimed in claim 1, further comprising a power storage unit for supplying power to the control circuit and the solid-state light emitting unit.

### Claim 4 (depends on 3)

The lighting device as claimed in claim 3, wherein the power storage unit is sealed in the receiving space.

### Claim 5 (depends on 3)

The lighting device as claimed in claim 3, wherein the power storage unit is disposed outside the housing, the housing further has a connecting portion, which is disposed on an outer surface of the housing and electrically connected to the control circuit and the solid-state light emitting unit, and the connecting portion is electrically connected to the power storage unit.

### Claim 6 (depends on 1)

The lighting device as claimed in claim 1, wherein the control circuit has a microcontroller.

### Claim 7 (depends on 1)

The lighting device as claimed in claim 1, wherein the solid-state light emitting unit has at least a light emitting diode (LED) die, a laser emitter or an organic light emitting diode (OLED) die.
