ここで、車両用警光灯１の組付けについて説明する。まず、第１の辺部ＬＥＤユニット３４ａをＬＥＤベース３２の左右の辺および上辺に取り付け、第２の辺部ＬＥＤユニット３４ｂをＬＥＤベース３２の下辺に取り付ける。また、第１の角部ＬＥＤユニット３６ａをＬＥＤベース３２の左上、右上および右下の角に、第２の角部ＬＥＤユニット３６ｂをＬＥＤベース３２の左下の角に取り付ける。 Here, assembly of the vehicle warning light 1 will be described. First, the first side LED units 34 a are attached to the left, right and upper sides of the LED base 32 , and the second side LED units 34 b are attached to the lower side of the LED base 32 . A first corner LED unit 36 a is attached to the upper left, upper right and lower right corners of the LED base 32 , and a second corner LED unit 36 b is attached to the lower left corner of the LED base 32 .

次に、ＬＥＤユニット３４ａ，３４ｂ，３６ａ，３６ｂの係止部３８ａ，３８ｂ，３９ａ，３９ｂと、対応する位置にある基板２０の係止スリット２４とを位置合わせし、差し込んで固定する。 Next, the engaging portions 38a, 38b, 39a, and 39b of the LED units 34a, 34b, 36a, and 36b are aligned with the engaging slits 24 of the substrate 20 at corresponding positions, and are inserted and fixed.

次に、ボルト７２を、座金７４を介して基板２０の貫通孔に挿通し、更に、ＬＥＤベース３２の円筒部３１に挿通して固定する。 Next, the bolt 72 is inserted through the through hole of the substrate 20 through the washer 74, and further inserted through the cylindrical portion 31 of the LED base 32 and fixed.

次に、光源部３０の後方から、配線コード８２（図３においては省略）を、ベース４０の配線孔４４、ヒートシンク５０の配線孔５６に挿通し、ベース４０、ヒートシンク５０を重ねて、ＬＥＤベースの円筒部３１、ベース４０の貫通孔４２、ヒートシンク５０の貫通孔５４の位置を合わせてヒートシンク５０の後方から、４本のトラスねじ７６で固定する。 Next, from behind the light source unit 30, the wiring cord 82 (not shown in FIG. 3) is inserted through the wiring hole 44 of the base 40 and the wiring hole 56 of the heat sink 50, the base 40 and the heat sink 50 are overlapped, and the LED base The cylindrical portion 31 of the base 40, the through hole 42 of the base 40, and the through hole 54 of the heat sink 50 are aligned, and the heat sink 50 is fixed with four truss screws 76 from behind.

この状態で、基板２０、光源部３０、ベース４０、およびヒートシンク５０の組み立て体の前面から、前面カバー１０を取り付け、樹脂で密閉する。 In this state, the front cover 10 is attached from the front of the assembly of the substrate 20, the light source section 30, the base 40, and the heat sink 50, and sealed with resin.

その後、配線コード８２を後部カバー６０の配線孔６４に挿通し、頭部を矩形状に形成した２本のＴネジ７８の頭部をガイド溝５８に挿入し、Ｔネジ７８のネジ部を後部カバーの貫通孔６２に挿通して、背面よりナット（図示せず）で締結する。 After that, the wiring cord 82 is inserted through the wiring hole 64 of the rear cover 60, the heads of two T screws 78 having rectangular heads are inserted into the guide grooves 58, and the screw portions of the T screws 78 are threaded into the rear portion. It is inserted through the through hole 62 of the cover and fastened with a nut (not shown) from the back.

このように組み付けた車両用警光灯１を点灯すると、図３に示すように、灯具本体の側面部に沿って側面部外方に光を照射することになる。図３のＬＥＤチップ３５ａ，３５ｂ，３７ａ，３７ｂから延びている矢印がそれぞれ光の照射方向を示している。 When the vehicle warning light 1 assembled in this manner is turned on, light is emitted outward along the side surface of the lamp main body, as shown in FIG. Arrows extending from the LED chips 35a, 35b, 37a, and 37b in FIG. 3 indicate the irradiation direction of light.

そして、灯具本体の左辺、右辺および上辺に配置されたＬＥＤチップ３５ａおよび、左上、右上、右下の角に配置されたＬＥＤチップ３７ａの発光は所定の着色光（例えば赤色）であり、下辺に配置されたＬＥＤチップ３５ｂおよび左下の角に配置されたＬＥＤチップ３７ｂの発光は所定の着色光とは異なる色の光（例えば白色光）であるよう構成されている。そのため、２種類の色の光を側方の周方向に出射することができ、異なる機能を発揮することが可能となる。 The LED chips 35a arranged on the left, right and upper sides of the lamp main body, and the LED chips 37a arranged on the upper left, upper right and lower right corners emit predetermined colored light (for example, red), and the lower side emits light. The light emitted from the arranged LED chip 35b and the LED chip 37b arranged at the lower left corner is light of a color different from predetermined colored light (for example, white light). Therefore, light of two kinds of colors can be emitted in the lateral circumferential direction, and different functions can be exhibited.

特に、本実施例のように、ＬＥＤチップ３５ａ，３７ａの発光を赤、黄、青、緑等の警光色とし、下辺に配置されたＬＥＤチップ３５ｂの発光色を白色とすると、周囲に警告を行い、注意喚起を促す警告灯と、作業を行うための作業灯との２つの機能を同時に発揮することが可能となる。 In particular, as in this embodiment, if the LED chips 35a and 37a emit red, yellow, blue, green, and other warning colors, and the LED chip 35b arranged on the lower side emits white light, the surroundings will be warned. By doing so, it is possible to exhibit two functions at the same time: a warning light for calling attention and a work light for performing work.

下辺に配置されたＬＥＤチップ３５ｂの発光色が白色であれば、作業時の見やすさの点で有利であるが、これに限定されず必要に応じて任意の色とすることができる。 If the emission color of the LED chips 35b arranged on the lower side is white, it is advantageous in viewability during work, but the color is not limited to this and can be any color as required.

なお、上記の例では、辺部ＬＥＤユニット３４ａ，３４ｂに配置するＬＥＤチップ３５ａ，３５ｂの数はそれぞれ５個であるが、個数に制限はなく、灯具の大きさや、必要な照度等の目的に合わせて任意に設定することができる。角部ＬＥＤユニット３６ａ、３６ｂに配置するＬＥＤチップ３７ａ，３７ｂの数についても同様である。 In the above example, the number of LED chips 35a and 35b arranged on the side LED units 34a and 34b is five, respectively, but there is no limit to the number of chips, and the size of the lamp and the required illuminance can be varied depending on the purpose. It can be set arbitrarily. The same applies to the number of LED chips 37a and 37b arranged in the corner LED units 36a and 36b.

また、ＬＥＤチップ３５ａ，３５ｂ，３７ａ，３７ｂの点灯の制御は、個別に制御されるように構成してもよく、協働して制御されるように構成してもよい。 Moreover, the lighting control of the LED chips 35a, 35b, 37a, and 37b may be configured to be individually controlled, or may be configured to be cooperatively controlled.

特に、着色光を発するＬＥＤチップ３５ａ，３７ａを、協働して周方向に順次点滅するように制御すると、光が回転しているように見えるので、一層注意喚起を促すことができ有利である。 In particular, if the LED chips 35a and 37a that emit colored light are cooperatively controlled to sequentially blink in the circumferential direction, the light appears to be rotating, which is advantageous in that it can further prompt attention. .

さらに、本実施例における、左下部のＬＥＤチップ３７ｂのように、着色光を発光するＬＥＤチップ３５ａと白色光を発光するＬＥＤチップ３５ｂとの境界にある角に、着色光を発光するＬＥＤチップを配置すると、光が３６０°回転しているように見えるので、特に好ましい。 Further, like the lower left LED chip 37b in this embodiment, an LED chip that emits colored light is placed at the corner between the LED chip 35a that emits colored light and the LED chip 35b that emits white light. The arrangement is particularly favorable as the light appears to rotate 360°.

あるいは、着色光を発光するＬＥＤチップ３５ａ，３７ａと、白色光を発するＬＥＤチップ３５ｂ，３７ｂとを個別に点灯制御可能に構成すれば、必要に応じて、一方の機能のみを利用することができ好ましい。 Alternatively, if the LED chips 35a and 37a that emit colored light and the LED chips 35b and 37b that emit white light are individually controllable, only one of the functions can be used as needed. preferable.

また、白色光を発光するＬＥＤチップ３５ｂ，３７ｂの光量を、着色光を発光するＬＥＤチップ３５ａ，３７ａの光量よりも大きくなるように構成すれば、作業灯の照射範囲への着色光の漏れの影響が低減されるので好ましい。 Further, if the light quantity of the LED chips 35b and 37b that emit white light is larger than the light quantity of the LED chips 35a and 37a that emit colored light, leakage of the colored light into the irradiation range of the work light can be prevented. It is preferable because the influence is reduced.

Therefore, overlapping explanations are omitted.

光源部１３０は、基板１２０の後方に配置され、基板１２０に垂直な部材により、フレーム形状に構成される。光源部１３０はアルミ製のＬＥＤベース１３２を備える。ＬＥＤベース１３２は、内側に、スリット状に切り欠いた円筒部１３１を周方向に４箇所等間隔に有する。 The light source unit 130 is arranged behind the substrate 120 and configured in a frame shape by members perpendicular to the substrate 120 . The light source unit 130 has an LED base 132 made of aluminum. The LED base 132 has four slit-shaped cylindrical portions 131 at equal intervals in the circumferential direction.

ＬＥＤベース１３２は、周方向に２箇所形成された突起１３２ａにより２つの区画に区分されている。車両に設置した際に上方に向かう区画１３３ａには、１１個のＬＥＤチップ１３５ａを周方向等間隔に配置した第１のＬＥＤユニット１３４ａが取り付けられている。一方、車両に設置した際に下方に向かう区画１３３ｂには、５つのＬＥＤチップ１３５ｂを周方向等間隔に配置した第２のＬＥＤユニット１３４ｂが取り付けられている。 The LED base 132 is partitioned into two sections by two protrusions 132a formed in the circumferential direction. A first LED unit 134a in which 11 LED chips 135a are arranged at regular intervals in the circumferential direction is attached to a section 133a facing upward when installed in a vehicle. On the other hand, a second LED unit 134b in which five LED chips 135b are arranged at equal intervals in the circumferential direction is attached to a section 133b facing downward when installed in the vehicle.
