A conventional LED unit for illumination does not have a function for setting a variable color tone in the main body, and if it is desired to change to an arbitrary color tone, the LED unit itself is replaced. Even if the color tone can be set without replacing, it is necessary to consider the color setting operation device separately provided outside and the wiring associated therewith.
By setting the rotation angle of a circular rotating printed circuit board in which a plurality of red, green, and blue LEDs, which are the three primary colors of light, are arranged, many color tone settings can be made by changing the combination of lighting of LEDs. The illumination LED unit is configured as described above, and the upper LED cover integrated with the rotary printed circuit board is used as a rotary operation unit for setting the color tone, which is effective for simplification of the configuration and operability. .

A lower printed board 2 is fixed to a fixed printed circuit board 2 with a primary power connection pin-type terminal 3 incorporated therein. In the rotating printed circuit board 4, a rotating printed circuit board feeding device 5, a red LED 6, a green LED 7, a blue LED 8 and an upper cover 9 are assembled by pressing them with a substrate pressing plate 10 and fixed in a rotatable state. The main body case 11 is closed with a rotating printed board setting position fixing plate spring 12 incorporated therein. However, although this LED unit is powered by the pin-type terminal 3 here, there is also a method using a lead wire or a base from the balance with the shape of the lighting fixture side, etc., and it is necessary to particularly limit the feeding method. Shall not.

また、本体ケース１１には、図２のように上部に色調設定目盛１１ａを設け、上部カバー９には色調設定位置表示マーク９ｂを設けている。 Further, as shown in FIG. 2, the main body case 11 is provided with a color tone setting scale 11a at the top, and the upper cover 9 is provided with a color tone setting position display mark 9b.

また、回転プリント基板４の上下面には、図３のように赤色ＬＥＤ６と緑色ＬＥＤ７と青色ＬＥＤ８と給電装置５を電気的に接続するためのプリント配線４ａ・４ｂを、固定プリント基板２の上下面には、図４のように一次側電源接続ピン形端子３から回転プリント基板給電装置５に配電するためのプリント配線２ａ・２ｂを施している。 Further, printed wirings 4 a and 4 b for electrically connecting the red LED 6, the green LED 7, the blue LED 8, and the power feeding device 5 as shown in FIG. As shown in FIG. 4, printed wirings 2 a and 2 b for distributing power from the primary-side power connection pin-type terminal 3 to the rotary printed circuit board feeding device 5 are provided on the lower surface.

また、回転プリント基板４の設定位置を適度な機械的圧力で固定保持するために、本体ケース１１に組込まれている回転プリント基板設定位置固定用板バネ１２と、上部カバー９における回転プリント基板設定位置固定用溝９ａとの噛み合わせの詳細は、図１におけるＡ−Ａ線断面図である図５による。 Further, in order to fix and hold the setting position of the rotating printed circuit board 4 with an appropriate mechanical pressure, the rotating printed circuit board setting position fixing plate spring 12 incorporated in the main body case 11 and the rotating printed circuit board setting in the upper cover 9 are provided. Details of the meshing with the position fixing groove 9a are shown in FIG.

また、回転プリント基板４と固定プリント基板２との電気的接続のために組込まれている回転プリント基板給電装置５と給電接触子５ａの詳細は、図１におけるＢ−Ｂ線断面図である図６によるが、ここで固定プリント基板２の上面プリント配線２ａにおける給電接触子５ａと接する範囲については、絶縁被覆を施さない通電可能な状態とする。 The details of the rotating printed board feeding device 5 and the feeding contact 5a incorporated for electrical connection between the rotating printed board 4 and the fixed printed board 2 are cross-sectional views taken along line BB in FIG. 6, here, the range of the upper surface printed wiring 2 a of the fixed printed circuit board 2 that is in contact with the power supply contact 5 a is in a state in which energization is possible without applying insulating coating.

以下、上記構成の動作を説明する。一次側電源接続ピン形端子３から取入れた電流は、固定プリント基板２のプリント配線２ａ・２ｂから回転プリント基板給電装置５を通じて回転プリント基板４のプリント配線４ａ・４ｂへと流れて、赤色ＬＥＤ６と緑色ＬＥＤ７と青色ＬＥＤ８の回路に供給されるが、ここで、回転プリント基板４の回転角度設定位置によって、色調パターンを考慮して構成された固定プリント基板２の上面プリント配線２ａと給電接触子５ａとが接触して通電状態となっている回路のＬＥＤが点灯をし、その場合の光の合成色がＬＥＤユニットとしての色調となる。 The operation of the above configuration will be described below. The current taken in from the primary side power connection pin-type terminal 3 flows from the printed wirings 2 a and 2 b of the fixed printed circuit board 2 to the printed wirings 4 a and 4 b of the rotating printed circuit board 4 through the rotating printed circuit board power supply device 5. The green LED 7 and the blue LED 8 are supplied to the circuit. Here, depending on the rotation angle setting position of the rotating printed board 4, the upper surface printed wiring 2a of the fixed printed board 2 configured in consideration of the color tone pattern and the feeding contact 5a And the LED of the circuit that is in the energized state are turned on, and the combined color of the light in that case becomes the color tone of the LED unit.

また、前記回転プリント基板４に固定した上部カバー９が色調設定用の回転操作部を兼ねており、上部カバー９の色調設定位置表示マーク９ｂを、本体ケース１１の色調設定目盛１１ａに回転させて合わせることで色調設定ができる。 Further, the upper cover 9 fixed to the rotating printed circuit board 4 also serves as a rotation operation unit for setting the color tone, and the color tone setting position display mark 9b of the upper cover 9 is rotated to the color tone setting scale 11a of the main body case 11.

また、赤色ＬＥＤ６と緑色ＬＥＤ７と青色ＬＥＤ８の配設数及び色調パターン数については、ＬＥＤ固有の明るさ及び色調パターンの考え方により組合せが幾通りも考えられるが、その一例として図７〜図９で色調パターンに関する説明をすると、図７のように赤色ＬＥＤ６をＲ１とＲ２の２回路、緑色ＬＥＤ７をＧ１とＧ２の２回路、青色ＬＥＤ８をＢ１とＢ２の２回路で点灯回路を編成した場合は、色調パターンの種類は図８の表のように２６種類となるが、ここで２６種類のうち点灯数に相違があって同色調のもの（たとえば、図８の表内のパターン数番号３・１５）も存在するため、同色のＬＥＤが２回路のみ点灯するもの（図８の表内のパターン数番号９・２１・２５）以外において点灯回路数が２以下のもの（図８の表内のパターン数番号１５・１７・１８・２３・２４・２６）を削除して色調の並びを整理すると、図９の表のように２０種類となる。 Further, regarding the number of arrangement of the red LED 6, the green LED 7, and the blue LED 8, and the number of color tone patterns, various combinations can be considered depending on the idea of the brightness and color tone pattern specific to the LED. Referring to the color pattern, when the red LED 6 is composed of two circuits R1 and R2, the green LED 7 is composed of two circuits G1 and G2, and the blue LED 8 is composed of two circuits B1 and B2, as shown in FIG. There are 26 types of color tone patterns as shown in the table of FIG. 8. Here, among the 26 types, there are differences in the number of lightings and the same color tone (for example, the pattern number numbers 3 and 15 in the table of FIG. 8). ), The number of lighting circuits is 2 or less (patterns in the table of FIG. 8) other than those in which only two LEDs of the same color are lit (pattern number numbers 9, 21, 25 in the table of FIG. 8). When you remove the down count numbers 15, 17, 18, 23, 24, 26) to organize a sequence of tones, the 20 types as shown in the table of FIG.
