Then, make lampshade 31 rotation predetermined angulars.Whereby, each projection 33b is disposed at following position, this position is the position that can be hooked in towards the back side of the joint cylinder section 4 of groove 5.Therefore, suppose to follow when bad when existing, even after having assembled bulb 1, make lampshade 31 down, also can suppress lampshade 31 and unexpectedly come off from body 2.
Then, utilize not shown anchor clamps to push lampshade 31 downwards.Whereby, the outer surface of the open side part 32b of lampshade 31, the front end face 4a of the cylinder section 4 that engages that has with body 2 comes in contact.Particularly, as shown in Figure 3, the outer surface of open side part 32b comes in contact with the bight 4c that is positioned at the most peripheral side that engages cylinder section 4.Meanwhile, the outer surface of described open side part 32b is close to the front end face 4a that engages cylinder section 4, and between the outer surface of described open side part 32b and described front end face 4a the minimum gap of formation.In other words, in the mode along front end face 4a, the outer surface of open side part 32b is set.
At last, under the state that utilizes described anchor clamps to come lampshade 31 is pushed, make this lampshade 31 by heating furnace, thereby make solid 37 sclerosis.Whereby, lampshade 31 then is installed on body 2, as shown in Figure 1, by lampshade 31 light source 11 is covered.
In the bulb 1 of described formation, make the joint cylinder section 4 of the body 2 that is supporting lampshade 31 front end face 4a, come in contact with the outer surface of the open side part 32b of lampshade main part 32, in the mode along the outer surface of open side part 32b, and this front end face 4a is set.Therefore, can make lampshade main part 32 open side part 32b, improve with the joint precision of the cylinder section 4 that engages of the body 2 in the outside of the opening edge 33 that is embedded in lampshade 31.
And, engage the tilt angle theta 1 of the front end face 4a of cylinder section 4, greater than the tilt angle theta 2 of the outer surface of the open side part 32b of lampshade main part 32, therefore, as mentioned above, under the state that can come in contact at the outer surface of bight 4c and open side part 32b, lampshade 31 is supported in body 2, and described bight 4c is the bight that the front end face 4a of joint cylinder section 4 becomes with the periphery 4b that engages cylinder section 4.Therefore, can positively be suppressed at the opening edge 33 of lampshade 31 and the junction surface that engages cylinder section 4 of body 2, form in the form of a ring the gap of the wedge-like that can see from the outside along circumferencial direction.Therefore, the exterior quality of bulb 1 is improved.
And, improve owing to engage precision, even when the gap that is formed at described junction surface has formed, also can make this gap extremely narrow, therefore, under the state of lighting a lamp of LED bulb, the heat of body 2 is easy to conduct to lampshade 31 via described junction surface.Therefore, not only can expect to dispel the heat to atmosphere from the outer surface of body 2, and can expect from lampshade 31 heat radiations.Therefore, the heat dispersion for the light source 11 that comprises led module can be guaranteed fully, thereupon, temperature because of light source 11 raise the excessively decline of the luminous efficiency that causes or variation of illuminant colour etc. can be suppressed.
In addition, the thermal expansion that is accompanied by body 2 and rises from the temperature of the lampshade 31 of these body 2 heat conduction, described extremely narrow gap disappears, and it is the state that contacts of formation face roughly that the front end face 4a that can expect to engage a section 4 and the outer surface of open side part 32b engage.When reaching aforesaid situation, can further make from the thermal diffusivity of body 2 towards lampshade 31 and improve.
