For example, as shown in Figure 10 B, when the height of the 1st wall portion 51 of the 1st pedestal 50 becomes higher than the height of the 1st reflecting wall portion 710, including the concaveconvex shape being brought by the 1st notch 710a, the 1st reflecting wall portion 71 is blocked by the 1st wall portion 51, so cover the portion boundary of the light of LED module 10, by the upper ora terminalis of the 1st wall portion 51, is stipulated.In the case, the height of the 1st wall portion 51 is certain, so cover the shape (contour shape of shadow) of the portion boundary of the light of LED module 10, becomes straight.That is the edge of the shadow, being produced by the 1st wall portion 51 becomes straight.Therefore,, in the case of the configuration shown in Figure 10 B, can not there is the concaveconvex shape of the 1st reflecting wall portion 71 that light distribution characteristic reason the 1st notch 710a of LED lamp produces and deteriorated problem.
But, as shown in Figure 10 C, when the height of the 1st wall portion 51 of the 1st pedestal 50 becomes lower than the height of the 1st reflecting wall portion 710, the concaveconvex shape of the 1st reflecting wall portion 710 being brought by the 1st notch 710a ora terminalis from the 1st wall portion 51 is run out of (Japanese: Fly び goes out The) and exposes, so cover the shape (contour shape of shadow) of the portion boundary of the light of LED module 10, by the contour shape of the 1st reflecting wall portion 71 that comprises the 1st notch 710a, is stipulated.In the case, as shown in the region P of the dotted line with Figure 10 C, the step (concavo-convex) producing by the 1st wall portion 51 and the 1st reflecting wall portion 710 is eye-catching, so that the contour shape of the above-mentioned shadow producing by this step also becomes is eye-catching.
Especially, in order to suppress the generation of creeping discharge between splicing ear 14 and the 1st pedestal 50 and space electric discharge, consider to make near height part than other splicing ear 14 of the 1st wall portion 51 and the 2nd wall portion 52 low.For example, as shown in figure 11, consider with the height of the 1st wall portion 51 and the 2nd wall portion 52 towards splicing ear 14 from both sides the mode of step-down gradually, in the 1st wall portion 51 and the 2nd wall portion 52, otch is set.In the case, thereby the shadow that the difference of height of the height of the 1st wall portion 51 and the 2nd wall portion 52 produces by the upper ora terminalis shape of the 1st wall portion 51 and the 2nd wall portion 52 is repeatedly convex-concave, so in order to eliminate this situation, as shown in the drawing, consider to make the height of the 1st wall portion 51 in aspect ratio the 1st pedestal 50 of the 1st reflecting wall portion 71 in reflection part 70 and the 2nd reflecting wall portion 72 and the 2nd wall portion 52 high.Thus, can make the portion boundary shape (contour shape of shadow) of the light that covers LED module 10 for straight.But, when making aspect ratio the 1st wall portion 51 of the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72 and the height of the 2nd wall portion 52 high, there is following problem,, in the region P of above-mentioned Figure 10 C, it is large that the difference of height being caused by the step of the 1st wall portion 51 and the 1st reflecting wall portion 710 becomes, and the shadow producing by this step is more eye-catching.
Like this, in the case of the configuration shown in Figure 10 C, the light of LED module 10 spills from the 1st notch 710a, the concaveconvex shape of the 1st reflecting wall portion 71 that the light distribution characteristic reason of result LED lamp the 1st notch 710a produces and deteriorated.
On the other hand, in the reflection part 70 in present embodiment, as shown in Figure 12 A, the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) height towards the 1st notch 71a(the 2nd notch 72a) position step-down gradually.
In the case, for example, as shown in Figure 12 B, when the height of the 1st wall portion 51 of the 1st pedestal 50 becomes higher than the height of the 1st reflecting wall portion 71, with Figure 10 B similarly, the shape (contour shape of shadow) of covering the portion boundary of the light of LED module 10 stipulates by the upper ora terminalis of the 1st wall portion 51, and it is straight to become.Therefore, in the case, the concaveconvex shape of the 1st reflecting wall portion 71 that the light distribution characteristic reason of LED lamp the 1st notch 71a produces and deteriorated problem can not produce.
And, in the present embodiment, as shown in Figure 12 C, in the case of the height of the 1st wall portion 51 of the 1st pedestal 50 become lower than the height of the 1st reflecting wall portion 71, different from the situation of Straight LED lamp in the comparative example shown in Figure 10 C, can suppress light distribution characteristic deteriorated of the LED lamp being caused by the 1st notch 71a.
; as shown in Figure 12 C; in the case of the height of the 1st wall portion 51 of the 1st pedestal 50 become lower than the height of the 1st reflecting wall portion 710; the concaveconvex shape of the 1st reflecting wall portion 71 being caused by the 1st notch 71a ora terminalis from the 1st wall portion 51 exposes; but the height of the 1st reflecting wall portion 71 is towards the position step-down gradually of the 1st notch 71a; so as shown in the region Q of the dotted line with Figure 12 C, can make the step (concavo-convex) producing by the 1st wall portion 51 and the 1st reflecting wall portion 71 be difficult for eye-catching.
; in the case of the configuration shown in Figure 12 C; the part of the light of LED module 10 beyond the 1st notch 71a is by the upper ora terminalis shading of the 1st reflecting wall portion 71; in the part of the 1st notch 71a by 51 shadings of the 1st wall portion; by the 1st wall portion 51 and the 1st reflecting wall portion 71, carry out regulation shadow; but discrete concavo-convex in order to avoid as far as possible making the bonding part of the upper ora terminalis of the 1st reflecting wall portion 71 and the upper ora terminalis of the 1st wall portion 51 to become, the height of the 1st reflecting wall portion 71 and the height of the 1st wall portion 51 are changed smoothly.Consequently, make the bonding part of the 1st wall portion 51 and the 1st reflecting wall portion 71 be difficult for eye-catching.That is, by the upper ora terminalis that makes the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72, tilt, absorb the deviation of the step being produced by the 1st wall portion 51 and the 1st reflecting wall portion 710 in Figure 10 C.
Like this, in the present embodiment, can make the contour shape (covering the shape of the portion boundary of the light of LED module 10) of the shadow producing by the step of the 1st wall portion 51 and the 1st reflecting wall portion 71 be difficult for eye-catching, even so there is the 1st notch 71a, the light distribution characteristic that also can suppress LED lamp is deteriorated.
Especially, as shown in figure 11, under the 1st pedestal 50 that has used the height that makes the 1st wall portion 51 and the 2nd wall portion 52 near formation lower than other part splicing ear 14, in the 1st wall portion 51 and the 1st reflecting wall portion 71, produce step and shadow is more eye-catching, but because make the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) height towards the 1st notch 71a(the 2nd notch 72a) position step-down gradually, so it is eye-catching to make the contour shape of the shadow producing by this step be difficult for.
, at the 1st notch 71a(the 2nd notch 72a) near make the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) upper ora terminalis tilt and form notch, and near splicing ear 14, make the 1st 51(of wall portion the 2nd wall portion 52) upper ora terminalis tilt and form in the Straight LED lamp of formation of notch, can make by the 1st notch 71a(the 2nd notch 72a) near the 1st 51(of wall portion the 2nd wall portion 52 that produces) and the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) deviation of the step that causes, with near the 1st 51(of wall portion the 2nd wall portion 52 by producing splicing ear 14) and the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) deviation of the step that causes works in the mode absorbing mutually.
Thus, as shown in figure 11, even if make the height of the 1st wall portion 51 and the 2nd wall portion 52 in the case of near the 1st pedestal 50 of formation lower than other part splicing ear 14 in use, also can effectively suppress light distribution characteristic deteriorated of LED lamp.
In addition, in the present embodiment, the 1st notch 71a and the 2nd notch 72a of reflection part 70 arrange in the mode of the splicing ear 14 away from LED module 10, are not arranged near of the splicing ear 14 of LED module 10.That is,, about the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72, with the height of the vicinity at splicing ear 14, become the mode higher than the height of other part and form.
The insulating properties that can suppress between splicing ear 14 and the 1st pedestal 50 thus, reduces.; because the 1st wall portion 51 of metal the 1st pedestal 50 and the 2nd wall portion 52 expose in the place that is formed with the 1st notch 71a and the 2nd notch 72a of the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72; so when formation the 1st notch 71a and the 2nd notch 72a, the reflection part 70 of insulating properties does not exist in this part near splicing ear 14.Consequently, between splicing ear 14 and the 1st pedestal 50, easily there is insulation breakdown.Therefore, by near that does not make the 1st notch 71a and the 2nd notch 72a be formed on splicing ear 14, make near height part than other splicing ear 14 of the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72 high, can be suppressed at thus between splicing ear 14 and the 1st pedestal 50 and produce insulation breakdown.
In addition, in the present embodiment, the upper ora terminalis shape (contour shape) of the part of the 1st reflecting wall portion 71 in reflection part 70 and the height change of the 2nd reflecting wall portion 72 is made as straight line, but is not limited to this.For example, the upper ora terminalis shape of the part of the height change of the 1st reflecting wall portion 71 and the 2nd reflecting wall portion 72 also can be made as curve.Below, use formation and the action effect of Figure 13 A～Figure 13 B to this variation to describe.Figure 13 A～Figure 13 C is the figure that represents the formation of the Straight LED lamp of variation of the present utility model.
In the reflection part 70A of this variation, as shown in FIG. 13A, the 1st 71A(of reflecting wall portion the 2nd 72A of reflecting wall portion) height towards the 1st notch 71aA(the 2nd notch 72aA) and gradually the upper ora terminalis shape of the part of step-down become curve.In addition, in this variation, this curve is from the 1st 71A(of reflecting wall portion the 2nd 72A of reflecting wall portion) bottom towards top, become convex.For example, can be by the 1st 71A(of reflecting wall portion the 2nd 72A of reflecting wall portion) height gradually the upper ora terminalis shape of the part of step-down be made as the circular shape of the radius of curvature with regulation.In this variation, be made as the circular arc of radius of curvature R=50mm.
In the case, for example, as shown in Figure 13 B, when the height of the 1st wall portion 51 of the 1st pedestal 50 becomes higher than the height of the 1st 71A of reflecting wall portion, with Figure 10 B and Figure 12 B similarly, the shape (contour shape of shadow) of covering the portion boundary of the light of LED module 10 stipulates by the upper ora terminalis of the 1st wall portion 51, and it is straight to become.Therefore, in the case, the concaveconvex shape of the 1st 71A of reflecting wall portion that the light distribution characteristic reason of LED lamp the 1st notch 71aA produces and deteriorated problem can not produce.
And, as shown in Figure 13 C, in the case of the height of the 1st wall portion 51 of the 1st pedestal 50 become lower than the height of the 1st 71A of reflecting wall portion, concaveconvex shape ora terminalis from the 1st wall portion 51 of the 1st 71A of reflecting wall portion being produced by the 1st notch 71aA exposes, but in this variation, the upper ora terminalis shape of the part of the height change of the 1st 71A of reflecting wall portion and the 2nd 72A of reflecting wall portion becomes curve, so as shown in the region R of the dotted line with Figure 13 C, compared with the situation of Figure 12 C, can make the step (concavo-convex) producing by the 1st wall portion 51 and the 1st 71A of reflecting wall portion more be difficult for eye-catching.Consequently, compared with the situation of Figure 12 C, can further suppress light distribution characteristic deteriorated of LED lamp.
Above, by the Straight LED lamp 1 in present embodiment, the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72 of reflection part 70) height towards the 1st notch 71a(the 2nd notch 72a) position step-down gradually, so when reflection part 70 is disposed to the 1st pedestal 50, can make by the 1st 51(of wall portion the 2nd wall portion 52) and the 1st 71(of reflecting wall portion the 2nd reflecting wall portion 72) produce step (concavo-convex) be difficult for eye-catching.Thus, even produced concaveconvex shape by the 1st notch 71a and the 2nd notch 72a at reflection part 70, the light distribution characteristic that also can suppress LED lamp is deteriorated due to this concaveconvex shape.
