LUMINAIRE

PROBLEM TO BE SOLVED: To provide a luminaire which secures reduction in thickness by suppressing a projection amount to indoors; which has an excellent design; which requires only narrow mounting space; and which can secure sufficient brightness feeling of space.SOLUTION: The thin luminaire can be achieved as LEDs 15, 16 are arranged on a surface of a flat plate-like substrate 12. Also, an angle formed by a beam having the highest intensity out of the beams emitted from the LED 16 and reflected on an outer peripheral surface 17b, and a vertical direction of a ceiling surface CL is between 90 degrees to 180 degrees. Thus, even when the LEDs 15, 16 are arranged on the same substrate, both illumination downward and illumination toward the ceiling surface CL can be achieved, so that brightness feeling of space can be secured. 【課題】屋内への突出量を抑えることで薄形化を確保し、デザイン性に優れ、取り付けスペースも狭くて足り、しかも空間の明るさ感を十分に確保できる照明装置を提供する。【解決手段】平板状の基板１２の表面上にＬＥＤ１５，１６を配置しているので、薄い照明装置とできる。又、ＬＥＤ１６から出射され外周面１７ｂで反射した光線のうち最も強度が高い光線と、天井面ＣＬの垂直方向とのなす角度 は、９０度〜１８０度であるので、同じ基板上にＬＥＤ１５，１６を配置しているにもかかわらず、下方への照明と、天井面ＣＬへの照明を両立でき、空間の明るさ感を確保できる。【選択図】図４
