As shown in (A) in Fig. 3, be equipped with multiple LED light source 21 at the lower surface 221 of lamp main body 22.
As shown in (B) in Fig. 3, LED light source 21 has LED211 and installs the installation base plate 212 of LED211.In addition, installation base plate 212 is equipped with connector 213.
As shown in (A) in Fig. 4, at the lower surface 221 of lamp main body 22, the chimeric recess 31 of LED light source 21 is set to radial from the center CP of lower surface 221 in the circumferential direction at predetermined intervals.Installation base plate 212 abuts with the bottom surface 312 of chimeric recess 31 and is assembled.
As shown in (B) in Fig. 4, chimeric recess 31 than the size of the installation base plate 212 of LED light source 21 and shape slightly large formed.At the internal perisporium 311 of chimeric recess 31, the inner side to chimeric recess 31 arranges at least 3 (being such as 5 at this) protuberances 32 highlightedly.
In addition, the bottom surface 312 corresponding with the position of protuberance 32 is provided with each and caves in 313.
As shown in (A) in Fig. 5, the front end face of protuberance 32 is substantially corresponding with the size of installation base plate 212 of the LED light source 21 being embedded into chimeric recess 31, abuts with the side end face 215 of installation base plate 212.
As shown in (B) in Fig. 5, protuberance 32 position is provided with depression 313, so the bight 214 above of installation base plate 212 does not abut with the bottom surface 312 of chimeric recess 31.In addition, position beyond protuberance 32 position, chimeric recess 31 is formed as larger than installation base plate 212, so the bight 214 above of installation base plate 212 does not contact with the intersection point of internal perisporium 311, i.e. bight, bottom surface 314 with the bottom surface 312 of chimeric recess 31, and contacts with bottom surface 312.
Therefore, installation base plate 212 bight 214 above can not with wearing and tearing due to mould and the bight, bottom surface 314 that may become the chimeric recess 31 of R shape when being formed abuts.
As shown in (A) in Fig. 6 and (B) in Fig. 6, the LED light source 21 being embedded into chimeric recess 31 presses installation base plate 212 by spring members 33 and fixes.
Spring members 33 has support sector 331 and linking part 332 at the lower surface 221 of lamp main body 22, and this support sector 331 is for being fixed to the position not arranging chimeric recess 31, and this linking part 332 links this support sector 331.Support sector 331 has pressing spring 333, and installation base plate 212 is pressed into the lower surface 221 of lamp main body 22 by this pressing spring 333.
Therefore, the assembling of LED light source 21, first, is embedded into the chimeric recess 31 of the lower surface 221 being arranged at lamp main body 22 by the installation base plate 212 of LED light source 21.At this moment, the location of installation base plate 212 is carried out by the protuberance 32 of chimeric recess 31.
Then, by rigging screw 34 through the through hole 334 of support sector 331 being arranged at spring members 33, and then the screw hole 222 of lamp main body 22 lower surface 221 is fastened to.
Thus, installation base plate 212 is pressed into the lower surface 221 of lamp main body 22 and fixes by the pressing spring 333 of spring members 33.
According to the LED illumination utensil 10 of embodiment of the present utility model described above, the installation base plate 212 being provided with LED211 is made to be fitted to the chimeric recess 31 of the lower surface 221 being arranged at light fixture 20 and to assemble.
At this moment, in the position that the internal perisporium 311 of chimeric recess 31 abuts with the side end face 215 of installation base plate 212, the fillet part produced due to the wearing and tearing of mould when the formation of chimeric recess 31 the internal perisporium 311 continuous print bottom surface 312 of chimeric recess 31 is being provided with depression 313, so can not abut with installation base plate 212.
Thereby, it is possible to make installation base plate 212 easily locate relative to lamp main body 22 and touch, assembly operation and radiating effect can be improved.
In addition, at the internal perisporium 311 of chimeric recess 31, the multiple protuberances 32 abutted with the side end face 215 of the installation base plate 212 being embedded into chimeric recess 31 are set, so installation base plate 212 easily can be located.
And then, arrange 3 with upper convex portion 32, so installation base plate 212 reliably can be positioned in chimeric recess 31 in the position surrounding installation base plate 212.
In addition, LED illumination utensil of the present utility model is not limited to aforesaid embodiment, can carry out suitable distortion and improvement etc.
Such as, in aforesaid embodiment, as the internal perisporium 311 of the chimeric recess 31 that the side end face 215 with installation base plate 212 abuts, exemplified with the situation being provided with multiple protuberance 32.
In addition, as shown in Figure 7, the internal perisporium 311 of chimeric recess 31B, throughout abutting with the side end face 215 of installation base plate 212 for whole when, is arranging the depression 313B of continuous print channel-shaped with internal perisporium 311 continuous print bottom surface 312.
