Description

本発明は、LED(Light Emitting Diode)を光源とする照明装置に関する。   The present invention relates to a lighting device using an LED (Light Emitting Diode) as a light source.

従来光源である白熱灯や蛍光灯に代わる光源として白色LEDを用いた照明装置(例えば、シーリングライトやLED電球)が普及しつつある。白色LEDは従来光源に比べ、低消費電力かつ高寿命である。一方で、一般的な白色LEDは、その特性上470nm〜500nmの波長の放射強度と610nm以上の波長の放射強度が不足しているため、物体の色の見え方に影響する光源の性質である演色性が乏しい。   Lighting devices using white LEDs (e.g., ceiling lights and LED light bulbs) as light sources in place of incandescent lamps and fluorescent lamps, which are conventional light sources, are becoming widespread. White LEDs have lower power consumption and longer life than conventional light sources. On the other hand, a general white LED is a light source property that affects the color appearance of an object because the radiation intensity of the wavelength of 470 nm to 500 nm and the radiation intensity of the wavelength of 610 nm or more are insufficient due to its characteristics. Poor color rendering.

このため、LEDを光源とする照明装置では、物体の色の再現度が低く、演色性を高めるための工夫が必要となる。そのための従来技術として、例えば特許文献1に記載の技術が知られている。特許文献1には、異なる波長のLEDとして電球色、昼光色の他に異なる波長のＬＥＤを3種類以上搭載し、演色性を高めることが開示されている。   For this reason, in the illumination device using the LED as a light source, the degree of reproduction of the color of the object is low, and a device for improving the color rendering property is required. As a prior art for that, the technique of patent document 1 is known, for example. Patent Document 1 discloses that three or more types of LEDs of different wavelengths other than a light bulb color and a daylight color are mounted as LEDs of different wavelengths to enhance color rendering.

特開2013-058394号公報JP, 2013-058394, A

特許文献1に記載の技術では、高演色性を実現するために電球色、昼光色の他に異なる波長のＬＥＤを3種類以上搭載しており、コスト増大の原因となる恐れがある。本発明は、低コストかつ演色性の高い照明装置の提供を実現することを目的とする。   In the technology described in Patent Document 1, in order to realize high color rendering, three or more types of LEDs of different wavelengths other than the bulb color and the daylight color are mounted, which may cause cost increase. An object of the present invention is to provide a low cost and high color rendering lighting device.

本発明は、赤色光を発光する赤色LEDと、青色光を発光する青色LEDと、電球色光を発光する電球色LEDと、昼光色光を発光する昼光色LEDとを備えた光源基板とを有し、前記赤色LEDからの前記赤色光と前記青色LEDからの前記青色光のみで、前記電球色LEDと前記昼光色LEDのみを発光させた場合の発光スペクトルでの谷部と傾斜部を補完することを特徴とする。 The present invention possess a red LED that emits red light, a blue LED that emits blue light, a warm white LED emitting bulb color light, and a light source substrate having a daylight color LED emitting daylight light, The valley portion and the slope portion in the emission spectrum when only the light bulb color LED and the daylight color LED are made to emit light are complemented by only the red light from the red LED and the blue light from the blue LED. I assume.

更に、上記異なる波長のLEDとは、ピーク波長610nm〜750nmの赤色光を発光するものと、ピーク波長470nm〜500nmの青色光を発光するものと、ピーク波長550nm〜650nmの電球色光を発光するものと、ピーク波長430〜460nmの昼光色光を発光するものとを特徴とする。   Furthermore, LED of the said different wavelength is what emits red light of peak wavelength 610nm-750 nm, what emits blue light of peak wavelength 470 nm-500 nm, and emits bulb color light of peak wavelength 550 nm-650 nm And light emitting daylight light having a peak wavelength of 430 to 460 nm.

更に、前記赤色光を発光するLEDと前記青色光を発光するLEDの個数比率は1:1とし、赤色光を発光するLEDと青色光を発光するLEDは交互に配置するものとし、その配置形状は環状とすることを特徴とする。   Furthermore, the ratio of the number of LEDs emitting red light to the number of LEDs emitting blue light is 1: 1, and the LEDs emitting red light and LEDs emitting blue light are alternately arranged, and the arrangement shape thereof Is characterized by having a ring shape.

本発明では、上記の異なる波長のLEDを複数有することで、低コストかつ演色性の高い照明装置を提供することができる。   In the present invention, by including a plurality of LEDs of different wavelengths as described above, a low cost and high color rendering lighting device can be provided.

一般的なLED照明装置に搭載される、電球色光を発光するLEDと、昼光色光を発光するLEDの他に、ピーク波長610nm〜750nmの赤色光を発光するLEDと、ピーク波長470nm〜500nmの青色光を発光するLEDとを追加することで、発光スペクトルが弱い波長の部分を補完し、演色性を高めることができる。   In addition to the LED that emits bulb color light and the LED that emits daylight color light that are mounted on a general LED lighting device, the LED that emits red light with a peak wavelength of 610 nm to 750 nm, and the blue color with a peak wavelength of 470 nm to 500 nm By adding an LED that emits light, it is possible to complement the portion of the wavelength where the emission spectrum is weak and to improve the color rendering.

さらに、赤色光を発光するLEDと、青色光を発光するLEDとの個数比率を1:1とし、交互に配置にすることで、色が混ざり、透光カバーを通して照射される光の色が、赤色光や青色光ではなく、電球色光と昼光色光のみを発光させる照明装置の照射光の色と同等になる。   Furthermore, the number ratio of the LED emitting red light to the LED emitting blue light is 1: 1 and the colors are mixed by arranging them alternately, and the color of the light irradiated through the translucent cover is It becomes equivalent to the color of the illumination light of the illumination device that emits only bulb color light and daylight color light, not red light or blue light.

図１に示すように、本発明の実施例に係る照明装置１００は、LEDを有した発光部である光源基板1と、LEDから発光される光を他方向に広げるためのレンズ2eを備えたLEDカバー2と、光を拡散するための透光カバー3と、光源基板1から発生する熱を放熱するための放熱板4と、制御装置を備えた電源基板5と、電源基板5を納めるための絶縁板6と、電源基板5と絶縁板6とを取り囲むためのバックボーン7とで構成される。   As shown in FIG. 1, a lighting apparatus 100 according to an embodiment of the present invention includes a light source substrate 1 which is a light emitting unit having an LED, and a lens 2e for spreading light emitted from the LED in the other direction. In order to enclose the LED cover 2, the light transmission cover 3 for diffusing light, the heat sink 4 for radiating the heat generated from the light source substrate 1, the power supply substrate 5 provided with a control device, and the power supply substrate 5 And a backbone 7 for surrounding the power supply substrate 5 and the insulating plate 6.

(配置)
光源基板1は、放熱板4の前面部4aに光源基板1の底面部が密着するようにしてねじ止めされている。バックボーン7の中央に位置する穴と絶縁板6の中央に位置する円筒部が一致するようにして、バックボーン7に絶縁板6が取り付けられる。絶縁板6の前面部には電源基板5の略弧形状と絶縁板6の略弧形状を合わせるようにし、さらに電源基板5の底面部側が絶縁板6の前面部6aと向かい合うようにして、絶縁板６を挟むように電源基板５がバックボーン7にねじ止めされている。 (Placement)
The light source substrate 1 is screwed so that the bottom of the light source substrate 1 is in close contact with the front surface 4 a of the heat sink 4. The insulating plate 6 is attached to the backbone 7 such that the hole located at the center of the backbone 7 and the cylindrical portion located at the center of the insulating plate 6 coincide with each other. Insulating the substantially arc shape of the power supply substrate 5 and the substantially arc shape of the insulating plate 6 on the front surface portion of the insulating plate 6 and further making the bottom portion side of the power substrate 5 face the front portion 6 a of the insulating plate 6 The power supply substrate 5 is screwed to the backbone 7 so as to sandwich the plate 6.

The LED cover 2 is covered to cover the light source substrate 1 and is screwed to the front side of the heat sink 4. Furthermore, a translucent cover 3 is attached to the holder 4 e so as to cover the light source substrate 1 and the LED cover 2.

(光源基板)
図２は、光源基板１の斜視図である。光源基板1は、図２に示すように、略環形状を成している。光源基板１の外周部には外周外側に向かってコネクタ接続部の突起1aを有する。光源基板１の中央部には円状の穴を有する。光源基板1の前面部1bには環状に一定間隔を有してLEDが配置される。光源基板１の中央部の円状の穴の外周部には、点対称の位置に2箇所、ねじ穴を避けるための半円状の切抜部1cを有する。しかし、切抜部1cの数や位置に関してはこれに限らない。 (Light source substrate)
FIG. 2 is a perspective view of the light source substrate 1. The light source substrate 1 has a substantially annular shape as shown in FIG. A protrusion 1 a of a connector connection portion is provided on the outer periphery of the light source substrate 1 toward the outer periphery. A circular hole is provided at the center of the light source substrate 1. LEDs are disposed on the front surface portion 1 b of the light source substrate 1 at regular intervals in a ring shape. At the outer peripheral part of the circular hole at the central part of the light source substrate 1, two semicircular cutouts 1 c for avoiding screw holes are provided at point symmetrical positions. However, the number and positions of the cutouts 1c are not limited to this.

The number of light bulb color LEDs 1 d and daylight color LEDs 1 e is arranged on the light source substrate 1 at a ratio of 1: 2 and arranged in a plurality of annular rows. In the light bulb color LED 1 d and the daylight color LED 1 e, the light color efficiency of the daylight color LED is higher due to the influence of the difference in conversion efficiency of the phosphor and the relative luminosity factor of the human eye. The luminous efficiency of the lighting device 100 can be improved by arranging the number of the bulb color LED 1d and the number of the daylight color LED 1e at a ratio of 1: 2. Furthermore, by arranging a plurality of LEDs in a ring, it is possible to efficiently widen the light to be irradiated widely. In addition, the red LEDs 1 f and the blue LEDs 1 g are alternately arranged on the same ring, and the number ratio thereof is 1: 1. By setting the number ratio of the red LED 1 f to the blue LED 1 to 1: 1, it is possible to easily mix red light and blue light with largely different emission wavelengths, and to reduce color unevenness irradiated to the light transmission cover 3 Can.

図４は、発光スペクトルを示しており、点線は電球色LED1ｄと昼白色LED1eのみを点灯した場合、実線は赤色LED1fと青色LED1ｇを追加点灯させた場合を示す。図４に示すように、電球色LED 1dと昼白色 1eのみ発光させた場合の発光スペクトルでは、谷部9aと傾斜部9bにおける光強度が低いが、赤色LED１fと青色LED１ｇを搭載することで谷部9aと傾斜部9bを補完することができ、高い演色性を実現する。   FIG. 4 shows the emission spectrum, and the dotted line shows the case where only the bulb color LED 1 d and the daylight white LED 1 e are lit, and the solid line shows the case where the red LED 1 f and the blue LED 1 g are additionally lit. As shown in FIG. 4, in the emission spectrum when only the light bulb color LED 1d and the day white 1e are emitted, the light intensity is low in the valley portion 9a and the inclined portion 9b, but by mounting the red LED 1f and the blue LED 1g The part 9a and the inclined part 9b can be complemented to achieve high color rendering.
