配光カバー部310は、ガラスなどからなる不燃材の光透過部材から形成されているものであり、LED基板113を覆うような略円板形状である。配光カバー部310の枠部120への固定方法については、実施の形態1で説明したものと同様である。 The light distribution cover portion 310 is formed of a light transmitting member made of a noncombustible material such as glass, and has a substantially disk shape so as to cover the LED substrate 113. The method of fixing the light distribution cover portion 310 to the frame portion 120 is the same as that described in the first embodiment.

図9、図10に示すように、配光カバー部310において、LED基板113の実装面1121と対向する面をカバー対向面3101とする。配光カバー部310は、LED111の前面にあたるカバー対向面3101の一部分に配光制御部材312が付着される。配光制御部材312が付着された部分を配光制御部311とする。 As shown in FIGS. 9 and 10, in the light distribution cover unit 310, the surface of the LED substrate 113 facing the mounting surface 1121 is referred to as the cover facing surface 3101. In the light distribution cover unit 310, the light distribution control member 312 is attached to a part of the cover facing surface 3101 corresponding to the front surface of the LED 111. The portion to which the light distribution control member 312 is attached is referred to as a light distribution control unit 311.

図11(a)(b)に示すように、配光カバー部310は、カバー対向面3101のうち、実装面1121のうち複数のLED111が配置された位置を含む配置領域1111に対向する対向領域3111に、配光制御部材312が付着される。 As shown in FIGS. 11A and 11B, the light distribution cover unit 310 faces an arrangement area 1111 including a position where a plurality of LEDs 111 are arranged on the mounting surface 1121 of the cover facing surface 3101. A light distribution control member 312 is attached to 3111.

図11(a)に示すように、配光カバー部310は、カバー対向面3101の対向領域3111のうち、複数のLED111のそれぞれに対向する複数の個別領域3112に、それぞれ配光制御部材312が付着される。
あるいは、図11(b)に示すように、カバー対向面3101の対向領域3111内の領域全部に、配光制御部材312が付着されてもよい。あるいは、カバー対向面3101の対向領域3111よりもやや広い領域に、配光制御部材312が付着されてもよい。
As shown in FIG. 11A, in the light distribution cover unit 310, among the facing regions 3111 of the cover facing surface 3101, the light distribution control member 312 has a light distribution control member 312 in each of the plurality of individual regions 3112 facing each of the plurality of LEDs 111. Be attached.
Alternatively, as shown in FIG. 11B, the light distribution control member 312 may be attached to the entire region in the facing region 3111 of the cover facing surface 3101. Alternatively, the light distribution control member 312 may be attached to a region slightly wider than the facing region 3111 of the cover facing surface 3101.

図10に示すように、配光カバー部310には、カバー対向面3101のうち、実装面1121のうち各LED111が配置された発光領域1112の略中心部から特定角度の範囲を個別領域3112として、この個別領域3112に配光制御部材312が付着される。
配光制御部材312が付着された配光制御部311は、LED111から照射される光を所定の角度へ配光する。図10に示すように、配光制御部311は、LED111の直下方向(0°)より特定角度θ°の範囲に配置されている事で、光源部300は所定の配光を得ることができる。
As shown in FIG. 10, in the light distribution cover unit 310, the range of a specific angle from the substantially central portion of the light emitting region 1112 in which each LED 111 of the mounting surface 1121 of the cover facing surface 3101 is arranged is set as an individual region 3112. , The light distribution control member 312 is attached to this individual region 3112.
The light distribution control unit 311 to which the light distribution control member 312 is attached distributes the light emitted from the LED 111 to a predetermined angle. As shown in FIG. 10, the light distribution control unit 311 is arranged in a range of a specific angle θ ° from the direction directly below the LED 111 (0 °), so that the light source unit 300 can obtain a predetermined light distribution. ..

図12は、光源部300の目標とする配光特性の参考図(実線、点線、1点鎖線)及びミニハロゲンを用いた非常用照明器具の配光特性の参考図(2点鎖線)である。
図12では、光度がピークのときを100%とした場合の相対光度を示している。また、図12では、光源部300の目標とする配光特性を3種類(実線、点線、1点鎖線)示し、ミニハロゲンを用いた非常用照明器具の配光特性を2点鎖線で示している。
FIG. 12 is a reference diagram (solid line, dotted line, one-dot chain line) of the target light distribution characteristic of the light source unit 300 and a reference diagram (two-dot chain line) of the light distribution characteristic of the emergency lighting equipment using the mini halogen. ..
FIG. 12 shows the relative luminous intensity when the peak luminous intensity is 100%. Further, in FIG. 12, the target light distribution characteristics of the light source unit 300 are shown by three types (solid line, dotted line, one-dot chain line), and the light distribution characteristics of the emergency lighting equipment using the mini halogen are shown by the two-dot chain line. There is.

図12の2点鎖線に示すように、ミニハロゲンを用いた非常用照明器具は、配光角度60°付近に光度値がピークになるように配光している。
そこで、配光制御部311は、LED111の発光面から垂直方向(直下方向(0°))付近の光を拡散し、光源部300においても、配光角度60°付近に光度値がピークになるように配光する。配光制御部311は、発光面(発光領域1112)から垂直方向(直下方向(0°))付近の光、例えば、直下方向(0°)よりθ=25°の範囲の光を拡散する。発光面(発光領域1112)から直下方向(0°)よりθ=25°の範囲に配光制御部311を設けることで、光源部300は図12の実線、点線、1点鎖線に示すような所定の配光特性を得ることができる。
ここでは、目標とする配光特性として、図12の実線、点線、1点鎖線に示す3種類の配光特性を示しているが、目標とする配光特性は、特定角度θ(約25°)から徐々に光度が上昇し、60°付近で相対光度が100%となるものであればよい。
As shown by the two-dot chain line in FIG. 12, the emergency luminaire using the mini-halogen distributes light so that the luminous intensity value peaks near the light distribution angle of 60 °.
Therefore, the light distribution control unit 311 diffuses the light in the vertical direction (directly downward direction (0 °)) from the light emitting surface of the LED 111, and the light intensity value also peaks in the light source unit 300 near the light distribution angle of 60 °. Light is distributed like this. The light distribution control unit 311 diffuses light in the vicinity of the vertical direction (directly downward direction (0 °)) from the light emitting surface (light emitting region 1112), for example, light in the range of θ = 25 ° from the direct downward direction (0 °). By providing the light distribution control unit 311 in the range of θ = 25 ° from the light emitting surface (light emitting region 1112) in the direction directly below (0 °), the light source unit 300 is as shown by the solid line, the dotted line, and the alternate long and short dash line in FIG. A predetermined light distribution characteristic can be obtained.
Here, as the target light distribution characteristics, three types of light distribution characteristics shown by the solid line, the dotted line, and the alternate long and short dash line in FIG. 12 are shown, but the target light distribution characteristics are the specific angle θ (about 25 °). ), The luminous intensity gradually increases, and the relative luminous intensity may be 100% at around 60 °.

特定角度θは25°近傍が好ましいが、例えば、20°以上30°以下の範囲内であっても良い。照明器具において所望の配光が実現されるように個別領域3112あるいは対向領域3111が設定され、配光制御部材312は、設定された個別領域3112あるいは対向領域3111の範囲に付着されることが好ましい。 The specific angle θ is preferably in the vicinity of 25 °, but may be, for example, in the range of 20 ° or more and 30 ° or less. It is preferable that the individual region 3112 or the facing region 3111 is set so that the desired light distribution is realized in the luminaire, and the light distribution control member 312 is attached to the range of the set individual region 3112 or the facing region 3111. ..

配光制御部311の形成方法は、拡散インク(配光制御部材312)を略円形状に配光カバー部310に印刷し付着させ、配光制御部311を形成している。
LED111からの光は、配光カバー部310の配光制御部材312が付着されていない箇所から直接照射される直接光と、配光制御部311を介して拡散された配光制御光とにより、所定範囲を照射する。
In the method of forming the light distribution control unit 311, the diffusion ink (light distribution control member 312) is printed and adhered to the light distribution cover unit 310 in a substantially circular shape to form the light distribution control unit 311.
The light from the LED 111 is generated by the direct light directly emitted from the portion to which the light distribution control member 312 of the light distribution cover unit 310 is not attached and the light distribution control light diffused through the light distribution control unit 311. Irradiate a predetermined area.

また、配光制御部311を拡散インクの印刷により形成している例を説明したが、拡散インクを用いずに印刷の濃淡によりグラデーションを形成した配光制御部311dでも良い。
グラデーションを形成した配光制御部311dとは、例えば、LED111の発光面から垂直方向の印刷濃度が濃く光透過率が低く、配光が広がるにつれ印刷濃度が薄く光透過率が高くなるように、配光制御部311dの印刷濃度を調整するものである。
Further, although the example in which the light distribution control unit 311 is formed by printing the diffusion ink has been described, the light distribution control unit 311d in which the gradation is formed by the shading of the print without using the diffusion ink may be used.
The light distribution control unit 311d that forms the gradation is, for example, so that the print density in the direction perpendicular to the light emitting surface of the LED 111 is high and the light transmittance is low, and the print density is low and the light transmittance is high as the light distribution spreads. It adjusts the print density of the light distribution control unit 311d.

また、所定の配光角度のみ照射されるように、配光制御部材312として光の不透過部材を用いて配光制御部311eを形成しても良い。
例えば、LED111の発光面(発光領域1112)から垂直方向付近に略円形状をした配光制御部311e(不透過部材)をアルミ蒸着などにより形成しても良い。
なお、アルミ蒸着で形成された配光制御部311eは、LED111からの光をLED基板113側へ反射させるので、枠筒部121内部および基板112に反射機能を持たせることで配光制御部311eにより反射された光が所定の角度へ照射され、配光カバー部310より照射される光量を増やし、光の照射効率を向上させることができる。
Further, the light distribution control unit 311e may be formed by using a light opaque member as the light distribution control member 312 so that only a predetermined light distribution angle is irradiated.
For example, a light distribution control unit 311e (impermeable member) having a substantially circular shape in the vicinity of the vertical direction from the light emitting surface (light emitting region 1112) of the LED 111 may be formed by aluminum vapor deposition or the like.
Since the light distribution control unit 311e formed by aluminum vapor deposition reflects the light from the LED 111 toward the LED substrate 113, the light distribution control unit 311e is provided with a reflection function inside the frame tube portion 121 and the substrate 112. The light reflected by the light is irradiated to a predetermined angle, the amount of light emitted from the light distribution cover unit 310 can be increased, and the light irradiation efficiency can be improved.

なお、上述したように、配光制御部311を付着させる範囲は、図11の(a)に示すように、各LED111の前面それぞれに応じるように配光制御部311を設けても良い。あるいは、図11の(b)に示すように、複数のLED111を1つの配光制御部311で応じるようにしても良い。 As described above, as shown in FIG. 11A, the light distribution control unit 311 may be provided so as to correspond to the front surface of each LED 111 in the range to which the light distribution control unit 311 is attached. Alternatively, as shown in FIG. 11B, a plurality of LEDs 111 may be accommodated by one light distribution control unit 311.

本実施の形態では、不燃部材により形成された略円板形状の配光カバー部310に、配光制御部311(配光制御部材312)が付着されている事により、レンズなどを用いずにLED111を所定の配光に制御する事ができる。 In the present embodiment, the light distribution control unit 311 (light distribution control member 312) is attached to the substantially disk-shaped light distribution cover unit 310 formed of the non-combustible member, so that a lens or the like is not used. The LED 111 can be controlled to a predetermined light distribution.

なお、付着手段として印刷および蒸着によるものを説明したが、拡散シートなどから形成される配光制御部311を配光カバー部310に貼り付けする付着手段であっても良い。 Although printing and thin-film deposition have been described as the bonding means, the bonding means may be used in which the light distribution control unit 311 formed of a diffusion sheet or the like is attached to the light distribution cover unit 310.

Further, the organic EL may be used as a substitute for the LED substrate 113.
