Definitions
- FIGS. 1 to 5 a first embodiment will be described with reference to FIGS. 1 to 5 .
- a virtual lamp center axis which passes through a center of the lamp unit 10 from the globe 15 to the base 17 is included, and descriptions will be made by setting a side on which the globe 15 is located when viewed from the base 17 to one end side, and a side which is opposite to the one end side, and on which the base 17 is located when viewed from the globe 15 to the other end side, in the lamp center axis.
- the housing 11 includes a resin housing 20 in a hollow shape, and a metal housing 21 which is arranged inside the resin housing 20.
- the resin housing 20 is formed of a resin material with an insulation property.
- the resin housing 20 is respectively open on one end side, and on the other end side, and is formed in a cylindrical shape of which a diameter contracts from one end side to the other end side.
- the resin housing 20 includes one end cylindrical portion 23a which is located on one end side, an inclined cylindrical portion 23b of which a diameter contracts toward the other end side from the one end cylindrical portion 23a, an intermediate cylindrical portion 23c which is located on the other end side of the inclined cylindrical portion 23b, an inclined cylindrical portion 23d of which a diameter contracts from the intermediate cylindrical portion 23c to the other end side, and the other end cylindrical portion 23e which is located on the other end side of the inclined cylindrical portion 23d.
- a plurality of mounting holes 28 in which first screws 27 as a plurality of screws which jointly fasten and fix the heat radiating plate 12 and the metal housing 21 to the resin housing 20 are screwed are formed in the board mounting unit 25.
- a plurality of escape holes 30 into which a plurality of second screws 29 which fasten and fix the light emitting module 13 to the heat radiating plate 12 intrude are formed in the board mounting unit 25.
- a positioning protrusion 31 which positions the metal housing 21 which is incorporated in the resin housing 20, the heat radiating plate 12, and the light emitting module 13, respectively, is provided in a protruding manner, in the board mounting unit 25.
- the power circuit holding unit 35 is formed by being divided into a first forming region from the one end cylindrical portion 23a of the resin housing 20 to the inclined cylindrical portion 23b and a middle position of the intermediate cylindrical portion 23c, and a second forming region of the other end cylindrical portion 23e.
- the first forming region is a region corresponding to an arranging region of the metal housing 21 which is arranged inside the resin housing 20.
- the power circuit holding unit 35 may be continuously formed over the first forming region and the second forming region.
- the width dimension of the holding wall 36 in the aligning direction of the pair of holding walls 36 is preferably 1 mm or greater, when considering insulation between the power circuit 16 and the metal housing 21, and rigidity of the holding wall 36.
- the metal housing member 39 cannot obtain sufficient thermal conductivity when the plate thickness does not have a certain thickness, and on the other hand, when the thickness exceeds a certain thickness, only mass increases, and thermal conductivity is not improved much, and therefore it is preferable to set the thickness to approximately 1 mm to 3.5 mm. In addition, it is more preferable to set the plate thickness of the metal housing member 39 to 2 mm.
- the metal housing member 39 is formed in a half cylindrical shape of which a diameter contracts from one end side to the other end side.
- the metal housing member includes one end half cylindrical portion 40a which is arranged along the inside of the one end cylindrical portion 23a of the resin housing 20, an inclined half cylindrical portion 40b which is arranged along the inside of the inclined cylindrical portion 23b, and the other end half cylindrical portion 40c which is arranged along the inside of the intermediate cylindrical portion 23c.
- the length on the other end of the the other end half cylindrical portion 40c is formed to the intermediate position of the intermediate cylindrical portion 23c.
- a plurality of insertion holes 49 into which the plurality of first screws 27 are inserted, and a plurality of screw holes 50a to which the plurality of second screws 29 are screwed, and a plurality of insertion holes 50b into which the plurality of second screws 29 are inserted are formed on the outer peripheral portion of the heat radiating plate 12.
- the third screw 51 is configured so as to jointly fasten and fix the cover 14, the light emitting module 13, and the heat radiating plate 12.
- a positioning groove 58 which is put into the positioning protrusion 31 of the board mounting unit 25 is formed on the outer peripheral portion of the board 55.
- a plurality of insertion holes 59 into which the plurality of first screws 27 are inserted, and a plurality of insertion holes 60 into which the plurality of second screws 29 are inserted are formed at the outer peripheral portion of the board 55.
- a plurality of insertion holes 61 into which the third screws 51 are inserted are formed at the inner peripheral portion of the board 55.
