The end cap includes a hollow cylindrical portion and a connection portion. The hollow cylindrical portion has an opening and an installation bottom surface, and an accommodating space is formed therebetween. The connection portion includes a plurality of first and second hollow connection tubes connected to the accommodating space. The circuit board is disposed on the installation bottom surface, and includes a plurality of first connection points and a plurality of second connection points. The first connection pins penetrate through the first hollow connection tubes respectively in order to connect to the first connection points. The second connection pins penetrate through the second hollow connection tubes respectively in order to connect to the second connection points. The tubular housing is connected to the end cap. ## Claims ### Claim 1 A lighting device having integrated end cap, comprising: an end cap comprising a hollow cylindrical portion and a connection portion, wherein the hollow cylindrical portion has an opening and an installation bottom surface, and an accommodating space is formed between the opening and the installation bottom surface, wherein the connection portion comprises a plurality of first hollow connection tubes and a plurality of second hollow connection tubes connected to the accommodating space; a circuit board disposed on the installation bottom surface, and comprising a plurality of first connection points and a plurality of second connection points; a plurality of first connection pins penetrating through the first hollow connection tubes respectively in order to connect to the first connection points; a plurality of second connection pins penetrating through the second hollow connection tubes respectively in order to connect to the second connection points; and a tubular housing connected to the end cap. ### Claim 2 (depends on 1) The lighting device having integrated end cap as claimed in claim 1, wherein the circuit board comprises two curved portions opposite to each other and two straight portions opposite to each other. ### Claim 3 (depends on 1) The lighting device having integrated end cap as claimed in claim 1, wherein the circuit board has a plurality of recesses disposed around the circuit board and an inner wall of the hollow cylindrical portion has a plurality of protrusions corresponding to the recesses respectively. ### Claim 4 (depends on 1) The lighting device having integrated end cap as claimed in claim 1, wherein the first hollow connection tubes comprises a main connection tube and two assistant connection tubes, wherein the main connection tube has a fixation post disposed on an outer wall thereof and the fixation post extends toward a direction of a central axis of the end cap, wherein each of the assistant connection tubes has a fixation hook disposed on an outer wall thereof and the fixation hook extends toward the direction of the central axis of the end cap. ### Claim 5 (depends on 4) The lighting device having integrated end cap as claimed in claim 4, wherein the main connection tube further has two positioning posts disposed on the outer wall thereof and the fixation post is disposed between the two positioning posts. ### Claim 6 (depends on 4) The lighting device having integrated end cap as claimed in claim 4, wherein each of the second hollow connection tubes has a plurality of limiting posts disposed on an outer wall thereof and a diameter of a circle formed by connecting top surfaces of the limiting posts to each other is less than or equal to an internal diameter of the first hollow connection tubes. ### Claim 7 (depends on 1) The lighting device having integrated end cap as claimed in claim 1, further comprises a light source board and a flexible board, wherein the light source board is connected to the circuit board via the flexible board. ### Claim 8 (depends on 7) The lighting device having integrated end cap as claimed in claim 7, wherein the flexible board is a flexible circuit board. ### Claim 9 (depends on 7) The lighting device having integrated end cap as claimed in claim 7, wherein the circuit board has an electrical connection groove and the flexible board penetrates through the electrical connection groove in order to be fixed with and electrically connect to the circuit board. ### Claim 10 (depends on 9) The lighting device having integrated end cap as claimed in claim 9, wherein the circuit board further has a plurality of fixture positioning grooves and the electrical connection groove is disposed between the fixture positioning grooves.
