## Abstract

A modular lighting device includes a base and a lamp head unit. The base includes a base body and a first connecting module disposed at a top end of the base body and having a first connecting portion and a first conductive portion. The lamp head unit includes a bottom seat, a lamp body disposed on the bottom seat, and a lamp shell connected to the bottom seat. The bottom seat includes a second connecting module disposed at a bottom end thereof and having a second connecting portion connected removably to the first connecting portion, and a second conductive portion electrically connected to the first conductive portion. The lamp shell has a maximum width disposed at a position adjacent to a bottom end thereof and smaller than or equal to that of the bottom seat.

## Claims

### Claim 1

A modular lighting device comprising:
a base including a base body and a first connecting module that is disposed at a top end of said base body and that has a first connecting portion and a first conductive portion;
a lamp head unit disposed removably on said base and including a bottom seat, a lamp body that is disposed on said bottom seat, and a lamp shell that covers said lamp body and that is connected to said bottom seat, said bottom seat including a second connecting module that is disposed at a bottom end of said bottom seat and that has a second connecting portion connected removably to said first connecting portion, and a second conductive portion electrically connected to said first conductive portion, said lamp body including a light-emitting member electrically connected to said second conductive portion, said lamp shell having a maximum width that is disposed at a position adjacent to a bottom end of said lamp shell and that is smaller than or equal to that of said bottom seat; and
a supporting unit that connects said lamp head unit removably to said base and that includes a supporting body having a top end and a bottom end, a third connecting module disposed on said top end of said supporting body, and a fourth connecting module disposed on said bottom end of said supporting body, said third connecting module having a third connecting portion connected removably to said second connecting portion of said second connecting module of said bottom seat of said lamp head unit, and a third conductive portion in electrical contact with said second conductive portion, said fourth connecting module having a fourth connecting portion connected removably to said first connecting portion of said first connecting module of said base, and a fourth conductive portion in electrical contact with said first conductive portion;
wherein said first and third connecting portions are configured as externally threaded rods, and said second and fourth connecting portions are configured as threaded holes engaging said externally threaded rods, respectively, and wherein each of said first and third conductive portions is cylindrical, and extends from a central portion of an end surface of a corresponding one of said externally threaded rods, and each of said second and fourth conductive portions has an end surface exposed in a corresponding one of said threaded holes and in electrical contact with a corresponding one of said first and third conductive portions.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The modular lighting device as claimed in claim 1, wherein said supporting body of said supporting unit has a flexible rod section.

### Claim 4

(canceled)

### Claim 5

(canceled)

### Claim 6 (depends on 1)

The modular lighting device as claimed in claim 1, wherein said base further includes a portable power supply disposed removably within said base body, and a charging connector disposed on said base body and electrically connected to said portable power supply.

### Claim 7 (depends on 1)

The modular lighting device as claimed in claim 1, further comprising a lampshade that includes a shade body surrounding said lamp head unit, and a head-connecting member disposed on said shade body and connected removably to said lamp head unit.

### Claim 8 (depends on 1)

The modular lighting device as claimed in claim 1, wherein said lamp shell is connected removably to said bottom seat.

### Claim 9 (depends on 1)

The modular lighting device as claimed in claim 1, wherein said lamp body of said lamp head unit further includes a heat dissipater connected to said bottom seat, and a circuit board connected to said heat dissipater and permitting said light-emitting member to be mounted thereon.
