Thus, the tongues 508, 510 protrude from the end sections 504, 506. Next, electrical wiring is applied (e.g., printed) on both sides of the sheet 5〇〇. Applying the electrical wiring includes forming a first receiving portion Π4 and a second receiving portion 115 for the light sources 102, 103 on one side of the sheet 500 (including a plurality of MCPCBs forming the tongue plates 508, 510); Forming a third receiving portion 116 and a fourth receiving portion 117 (including forming a plurality of MCPCBs at the end portions 504, 506) for driving the cells 16a, 16b on the other side of the sheet 500; The electrical wiring of the respective driving units 106a' 106b and their respective light sources 1〇2, 1〇3 is connected via a hole passing through the sheet 5〇〇. The green sheet 500 is then formed into a predetermined shape of the heat sink 112 of the illumination device 100 by suitable metal forming techniques such as stamping, bending and rolling. More specifically, the end sections 504, 506 are bent at the boundary between the sections and the main section 502; the main section 502 is formed into a cylindrical shape to make the special section The segments 5 0 4, 5 0 6 extend in the cylinder along their diameters adjacent to each other and extend the tongues 5〇8, 5 1 相反 in opposite directions until they are in opposite directions and perpendicular to the The equal end sections 5〇4, 506 extend. Thereby, the light sources 102, 103 become positioned on the top surface of one of the tongue plates 508' 510 to emit light away from the heat sink 112. Thereafter, the light sources 102, 103 are mounted on respective MCPCBs at the first receiving portion 114 and the second receiving portion 115, and the driving units 161517.doc 201243206 106a, 106b are mounted in the third receiving portion. 116 and the fourth receiving portion 丨 17 are on their respective (10) (10). Further, the electrical connection unit UG8 is mounted on the fourth receiving portion 117 or mounted on the third receiving portion 116. Next, the light output unit 104 is mounted at the top of the cylindrical main portion 118 of the heat sink 112, thereby enclosing the light sources 1〇2, 1〇3. Finally, although not shown in Figures ia through, the appropriate casing joint is mounted at the bottom of the cylindrical main portion 118 of the heat sink 112. The electrical connection unit 108 is coupled to the sleeve joint. Referring to Figure 2, a portion of the second embodiment of the illumination device is shown. More specifically, an alternative shape of the heat sink 200 is shown. In this embodiment, the heat sink 200 also has a cylindrical main portion 2〇2 (which has been formed by one of the rectangular main sections of the heat sink blank), but the heat sink 2 has the main portion 202 Adjacent one single end section 2〇4 and one single tongue section 2〇6 from the end zone slave 2〇4 dog. The heat sink 2 has been formed into a predetermined shape from a blank according to a principle similar to the heat sink of the first embodiment such that the end section 204 is parallel to the diameter of one of the circular main portions 2〇2 but Extending from the off-center position and causing the tongue 2〇6 to extend perpendicular to the end section 204. The tongue plate 2〇6 has a first receiving portion that carries a light source (not shown), and the end portion includes a second receiving portion that carries the drive unit and the electrical connection unit (not shown). The first receiving portion and the second receiving portion have been formed on the same side of the heat sink blank. As shown in an enlarged portion of FIG. 2, one end portion 208 of the main portion 2〇2 opposite the end portion 204 is received in the end portion 2〇4 and the main portion 202. One of the boundaries is located in one of the stepped seats to provide a smooth outer surface of one of the cylindrical main portions 202 of the circle 161517.doc •9·201243206. Further, the seam between the end portion 2〇8 of the main portion 202 and the stepped seat 210 may be covered by a filling material or a coating. The same applies to the corresponding seam of the first embodiment described above. According to a third embodiment of the illumination device, as shown in Figures 3a to 3c, the main portion 3〇2 of the heat sink 300 is funnel-shaped. As in this second embodiment, one end section 3〇4 of the heat sink 300 extends parallel to the diameter of one of the main portions 302 but is offset from the center, and the end section 3〇4 is included in the main part. One of the 302, a larger opening, extends perpendicular to the end section 304 to a tongue 306. The tongue 306 carries a light source (not shown) that emits light that passes through a planar light output unit 308 that covers the upper opening away from the heat sink 300. According to a fourth embodiment of the illumination device 400, the heat sink 402 is generally dome-shaped as shown in Figures 4a to 4c. The heat sink 402 includes a dome shaped main section 404' having a gap 406 in the wall and an end section 4'8' that has been bent for use as a building structure for the light source and other electronic units. The end section 408 has a tongue-like first receiving portion 4 1 0 'for extending perpendicular to a central axis of the main portion 4〇4; and a second receiving portion 412 One of the inner ends of the dome extends toward the opening thereof obliquely to the central axis. The lighting device further includes a casing joint 414 having a dome sector 416 that fills one of the gaps 406. The formation of the heat sink 402 is facilitated by having the sleeve joint 414 form part of the dome. According to a fifth embodiment of the illumination device 600, as shown in FIG. 6, the 161517.doc • 10· 201243206 heat sink 602 has been formed as a substantially cylindrical outer casing having a cylindrical portion 603 and a plate portion. (The plate-like portions have been bent toward the inside of the cylindrical portion 6〇3 and extend across and adjacent to each other inside the cylindrical portion 6〇3). Each of the plate-like portions includes adjacent receiving portions 6〇4, 6〇6 positioned on the same side of the plate-shaped blade. A light source comprising a plurality of light-emitting elements 608 and a drive/electrical connection unit 61 are disposed on respective receiving portions 6〇6, 6〇4 of a single-sided configuration. One of the receiving portions 604' 606 protrudes from the second receiving portion 6〇4 by a tongue, and thus the light-emitting element 608 carried by the first receiving portion is mounted One of the cylindrical portions 6〇3 has a central axis parallel to one of the planes. Therefore, the light-emitting element 130 of the first embodiment can be regarded as being mounted horizontally as if it is mounted vertically. Since the light-emitting elements 6 〇 8 are arranged on the opposite receiving portions and thus face in opposite directions, an advantageous light distribution is obtained particularly when the light-emitting elements 6 〇 8 are covered by the X-ray light-forming light output unit. A sleeve joint 612 is provided at the rear end of one of the illumination devices 600. In this embodiment, the heat sink 6〇2 is integrally attached to a MCPCB' thus integrating the light source and the housing. Alternatively, as described in connection with the above embodiments, the receiving portions may be configured to have individual MCpcB^.
