The outer circumference of the engage ring is formed with at least one pivotal seat, and the outer circumference of each of the at least one lamps is formed with a spherical shaft having the inclined angle being adjustable and pivotally connected in the pivotal seat. The illumination device is able to be rapidly connected to a conventional gas combustor, when the above two are combined as one piece, a light source of each of the at least one lamps can be turned on through adjusting the inclined angle of each of the at least one lamps relative to the engage ring, so the generated lights can be projected to the combusting location of the gas combustor to provide required illumination during the combustion operation. ## Claims ### Claim 1 An illumination device for use with gas combustor, including: an engage ring, wherein the inner circumference thereof is formed with an engage port allowing a gas combustor to be engaged, and the outer circumference thereof is installed with at least one pivotal seat; and at least one lamp, wherein each of said at least one lamp includes a housing, the outer circumference thereof being radially installed with a spherical shaft having the inclined angle being adjustable and pivotally connected in said pivotal seat, and the outer circumference thereof being formed with a slot allowing a switch unit to be disposed therein; a base disposed in said housing and including a chamber for accommodating at least one battery and a positioning slot for positioning a light source, and said at least one battery being electrically connected to said light source through said switch unit; and an end cover disposed in an opening of said housing and including a through hole for accommodating said light source and allowing the generated lights to be projected out; wherein the periphery of an opening of said pivotal seat is formed with at least two grooves, and the depth of said pivotal seat is greater than the radius of said spherical shaft. ### Claim 2 (depends on 1) The illumination device for use with gas combustor as claimed in claim 1, wherein said engage ring includes two semi-circular pieces, inner ends of said two semi-circular pieces are connected by a connection piece, and outer ends thereof are correspondingly formed with a buckle hook and a buckle slot capable of being mutually buckled, so the inner circumference of said engage ring is formed with said engage port when said buckle hook is buckled in said buckle slot. ### Claim 3 (depends on 2) The illumination device for use with gas combustor as claimed in claim 2, wherein inner circumferences of said two semi-circular pieces of said engage ring are axially formed with a plurality of positioning slots arranged in parallel. ### Claim 4 (depends on 1) The illumination device for use with gas combustor as claimed in claim 1, wherein said light source includes a first pin and a second pin, said first pin of said light source is in direct contact with one electrode of said at least one battery, and said second pin is vertically arranged at the rear side of said base, and a gap is formed between said second pin and said switch unit; when said switch unit is operated, said switch unit is moved from a first position to a second position in said slot, and said switch unit is enabled to push said second pin to be in contact with the other electrode of said battery, thereby forming an electrically connecting status for turning on said light source. ### Claim 5 (depends on 4) The illumination device for use with gas combustor as claimed in claim 4, wherein opposite sides of said slot are respectively formed with a pair of first positioning slots and a pair of second positioning slots, opposite sides of said switch unit are formed with a pair of positioning tenons; when said switch unit is pushed, said pair of positioning tenons is able to be selectively positioned in said pair of first positioning slots or said pair of second positioning slots in said slot. ### Claim 6 (depends on 4) The illumination device for use with gas combustor as claimed in claim 4, wherein said switch unit is axially connected to an elastic member. ### Claim 7 (depends on 6) The illumination device for use with gas combustor as claimed in claim 6, wherein said elastic member is a conical spring, and said switch unit has an axially protruding tenon for being sleeved in said spring. ### Claim 8 (depends on 4) The illumination device for use with gas combustor as claimed in claim 4, wherein the outer circumference of said base is formed with a pin slot allowing said second pin to be received. ### Claim 9 (depends on 1) The illumination device for use with gas combustor as claimed in claim 1, wherein the outer circumference of said housing is radially installed with a handgrip part capable of be held, and the outer circumference of said end cover is formed with a pair of cover tenons capable of being held. ### Claim 10 (depends on 1) The illumination device for use with gas combustor as claimed in claim 1, wherein said battery is a mercury battery, and said light source is a light emitting diode.
