[assemble method of Straight LED]

Then, for the assemble method of the Straight LED 1 that embodiment of the present utility model relates to, Figure 12 is utilized to be described.Figure 12 is the figure of each operation illustrated in the assemble method of the Straight LED that embodiment of the present utility model relates to.

First, as Figure 12 (a) illustrates, configure the second base station 60 at the first base station 50.Specifically, the afterburning portion 55 of the first base station 50 loads the second base station 60.

Then, as Figure 12 (b) and Figure 12 (c) illustrates, the second base station 60 configures reflection part 70.Under the state that reflection part 70 is configured in the second base station 60, reflection part 70 is pushed upward by the reinforcing in afterburning portion 55.Further, the first notch part 71a of the first reflection wall portion 71 of reflection part 70 is larger than the first protuberance 51a of the first base station 50, and the second notch part 72a of the second reflection wall portion 72 of reflection part 70 is larger than the second protuberance 52a of the first base station 50.Therefore, as Figure 13 (a1) illustrates, at the first notch part 71a of the first reflection wall portion 71, engage the bottom of the first protuberance 51a of the first base station 50.Further, as Figure 13 (a2) illustrates, at the second notch part 72a of the second reflection wall portion 72, the bottom of the second protuberance 52a of the first base station 50 is engaged.

Then, as Figure 12 (d) illustrates, LED module 10 is configured at the first base station 50.Now, by the reinforcing in afterburning portion 55, substrate 11, is clamped by reflection part 70 and the second base station 60 and the first protuberance 51a and the second protuberance 52a.That is, can by the both ends of the width of substrate 11, be clipped in reflection part 70 and between the second base station 60 and the first protuberance 51a and the second protuberance 52a.

Accordingly, as Figure 12 (e) illustrates, LED module 10 can be fixed to the first base station 50.Now, by the press-in of substrate 11, reflection part 70 is pushed downwards.Therefore, as Figure 13 (b1) illustrates, the first protuberance 51a of the first base station 50, becomes the first notch part 71a relative to the first reflection wall portion 71 of reflection part 70 and the state (contactless state) of floating.Further, as Figure 13 (b2) illustrates, the second protuberance 52a of the first base station 50, also becomes the second notch part 72a relative to the second reflection wall portion 72 of reflection part 70 and the state (contactless state) of floating.

And, then, collocation point circuit for lamp 80 on reflection part 70, by connecting line 90, LED module 10 is electrically connected to each other, and, carry out the electrical connection of LED module 10 and lamp circuit 80, further, 33 to carry out for electrical prongs 32 electrical connection with lamp circuit 80 by going between.Then, in the mode covering lamp circuit 80, circuit case 85 is assembled to the first base station 50.Then, make after these parts of combination insert in framework 20, power supply lamp holder 30 and non-powered lamp holder 40 are assembled to the both ends of framework 20 each.

So, in the present embodiment, on the first base station 50, the second base station 60, reflection part 70 and LED module 10 is overlapping according to this order.Accordingly, with by reflection part 70, second base station 60 (metal base station) and LED module 10 according to compared with the overlapping situation of this order, the thermal diffusivity of LED module 10 reduces hardly, on the contrary, the light escaping to the back side of substrate 11 is reflected by reflection part 70, therefore, it is possible to raising light extraction efficiency.That is, the raising of light extraction efficiency and both raisings of thermal diffusivity can be realized.

[action effect etc.]

In the Straight LED 1 of the present embodiment, the circuit case 85 covering lamp circuit 80 possesses, and clamps the second clamping part 852 of the first clamping part 851 of the first wall portion 51 of the first base station 50 and the second wall portion 52 of clamping the first base station 50.Specifically, the first clamping part 851 is made up of the first inner wall part 851a and the first outside wall portions 851b, clamps the first wall portion 51 by the first inner wall part 851a and the first outside wall portions 851b.Further, the second clamping part 852 is made up of the second inner wall part 852a and the second outside wall portions 852b, clamps the second wall portion 52 by the second inner wall part 852a and the second outside wall portions 852b.
