[effect etc.]
Then, about the action effect of the straight tube LED 1 relating to present embodiment, also comprise and reach process of the present utility model and illustrate.
In recent years, the stripization progress of LED module, have studied the use aspect ratio big long strip shape object situation as the installation base plate installing LED element.But, if using the installation base plate of strip, then there is warpage on installation base plate.
Particularly, if use resin substrate (such as CEM-3) is as installation base plate, then installation base plate warpage significantly.It is believed that this is the coefficient of linear expansion by resin substrate and the hot exapnsion difference when the variations in temperature that the difference of coefficient of linear expansion of the metal line (metal pattern) that the element installed surface of resin substrate is formed causes and produces.That is, due to the thermal stress of resin substrate and warpage.
On the other hand, in order to make the thermal diffusivity of the heat produced by LED element improve, it is desirable to by thinning for the installation base plate of installation LED element.Such as, have studied use thickness is that the resin substrate of below 1mm is as installation base plate.
So, if using the resin substrate of the strip that thickness is thin as installation base plate, then the quantitative change of installation base plate warpage simply, and warpage is big.I.e., not only installation base plate is thinning and mechanical strength diminishes, and due to the thermal stress of resin substrate and the biggest warpage of installation base plate.Its result, has LED element to deviate, can not obtain the problem of desired light distribution characteristic from the position of regulation.
Therefore, have studied as shown in Figure 5 in the case of the installation base plate 11A being made up of resin substrate employing the strip being provided with LED element 12, in order to suppress the warpage of installation base plate 11A, use the two sides of such as resin substrate about 1mm thickness to be formed with the two sides substrate (such as CEM-3) of metal, as shown in Figure 6 in the situation forming virtual metal line 13A (metal pattern) with the face (back side) of the element installed surface opposition side of installation base plate 11A.In the case of Gai, installation base plate 11A and base station 30 be used between metal line 13A and base station 30 bonding agent 61 of coating and be adhesively fixed.
But, even if the known back side at the installation base plate 11A being made up of resin substrate forms virtual metal line 13A, if in order to by thinning for overall for installation base plate 11A thickness and by thinning for metal line 13A, then metal line 13A is stretched by the thermal stress of resin substrate, it is impossible to suppress the warpage of installation base plate 11A well.
On the other hand, if being thickeied by the thickness of metal line 13A to suppress the warpage of installation base plate 11A, then the thickness of the installation base plate 11A that metal line 13A is also included is thickening, it is impossible to realize thin installation base plate.Therefore, the problem that generation can not make the heat heat radiation efficiently etc. produced by LED element 12.
So, so far, employ strip and thin resin substrate that thickness is below 1mm as installation base plate in the case of, it is extremely difficult to the warpage of suppression installation base plate.

In the case of Gai, the degree of depth of the recess of the installation base plate 11 constituted by being bent by resin substrate can be set to below the thickness of installation base plate 11.Bending width time i.e., by making end, the long limit bending by resin substrate is below the thickness of resin substrate, and the height (degree of depth of recess) that can make the inner surface of the bending section 11a after having carried out bending is below the thickness of installation base plate 11.Such as, in the case of the thickness of installation base plate 11 (resin substrate) is below 1mm, the degree of depth of recess is below 1mm.
So, by making below the thickness that the degree of depth is installation base plate 11 of the recess of installation base plate 11, it is possible to make the heat radiation from the back side of installation base plate 11 improve, it is possible to make the heat produced by LED element 12 dispel the heat efficiently.
And then, in present embodiment, possessing the base station 30 for keeping installation base plate 11, installation base plate 11 is fixed in base station 30 in the way of pair of curved portion 11a is positioned at base station 30 side.
Thereby, it is possible to obtain the area of space surrounded by pair of curved portion 11a and element mounting portion 11b and base station 30.I.e., it is possible to the part surrounded at the recess by being made up of pair of curved portion 11a and element mounting portion 11b and base station 30 forms area of space.
Thus, as it has been described above, utilize this area of space can receive component 41 or power circuit etc..Additionally, by arranging bonding agent 61 at the area of space surrounded by pair of curved portion 11a and element mounting portion 11b and base station 30, it is possible to installation base plate 11 and base station 30 are adhesively fixed.Thus, though the erection space of LED element 12 be equal in the past, it is also possible to the contact area increase with bonding agent 61 is equivalent to the amount of bending section 11a.Its result, can not only make the adhesive strength of installation base plate 11 and base station 30 improve, due also to the heat produced by LED element 12 can be made to conduct to base station 30 efficiently it is thus possible to make thermal diffusivity improve via bonding agent 61.
