摘要： PROBLEM TO BE SOLVED: To provide a lighting apparatus which has a light guide plate for guiding light of a plurality of LEDs and in which luminance unevenness of a light guide plate is suppressed.SOLUTION: LEDs 2 are arranged in a polygonal annular shape, a light guide plate 3 is disposed in an annular shape, light of the LEDs 2 is introduced from an inner periphery surface and derived to the outside while propagating in an outer periphery direction. The inner periphery surface of the light guide plate 3 has a series of plurality of incidence surfaces 32 facing the LEDs 2 on each side of the polygonal annular shape formed by the LEDs 2. At a connection part 32a of the incidence surfaces 32 adjacent to each other, a corner member 36 is formed integrally with the light guide plate 3 so as to fill the corner. Out of the light of the LEDs 2 on each side, the light entering the light guide plate 3 from the surface of the corner member 36 refracts in such a manner that it travels at a larger angle laterally with respect to the light propagation direction by the light guide plate 3 on the surface. Therefore, propagation region A1 of the light of the LEDs 2 on each side of the light guide plate 3 is expanded, and the luminance of each propagation region A1 is lowered. As a result, difference in luminance between a region A2 where the propagation regions A1 adjacent to each other overlap and a region A3 where they do not overlap becomes small.

摘要： PROBLEM TO BE SOLVED: To reduce an irradiation light luminance difference between a luminaire central portion and a luminaire outer edge and to enhance lighting efficiency, in a luminaire having LEDs as light sources.SOLUTION: A luminaire 1 comprises: an LED array 2 having LEDs 21; a housing 3 for holding the LED array 2; and a diffusion transmission cover 4. An LED array holding surface 3A of the housing 3 has specular reflectivity. The diffusion transmission cover 4 is configured so as to gradually reduce a distance from the housing 3 toward a luminaire outer edge side. Light that is emitted from the LEDs 21 and is reflected in a luminaire outer edge direction by the diffusion transmission cover 4 is specularly reflected by the LED array holding surface 3A and easily reaches a luminaire outer edge. Accordingly, an irradiation light luminance difference between a luminaire central portion and the luminaire outer edge is reduced. Further, an incident angle θ of the light that is specularly reflected by the LED array holding surface 3A and is made incident to the diffusion transmission cover 4 on a boundary surface 4A between the diffusion transmission cover 4 and an outside is reduced. Accordingly, total reflection of the light on the boundary surface 4A is suppressed, and lighting efficiency is enhanced.

摘要： PROBLEM TO BE SOLVED: To obtain a desired quantity of light by a lighting instrument and to improve instrument efficiency by improving heat radiation.SOLUTION: A lighting instrument 1 includes a light emission part 2A having a plurality of LEDs 21A which are annularly arranged, a light emission part 2B having a plurality of LEDs 21B which are annularly arranged, and an annular light guide member 3A which guides and radiates light emitted by the light emission part 2A. The light emission parts 2A, 2B differ in diameter from each other, and are arranged concentrically. Consequently, even when a necessary number of LEDs 21A, 21B for obtaining a desired quantity of light cannot be arranged at one light emission part, those LEDs 21A, 21B are arranged divisionally at the light emission parts 2A, 2B, so that the desired quantity of light can be obtained. Further, even when the LEDs 21A, 21B are small in number enough to be arranged at one light emission part, the LEDs 21A, 21B are arranged divisionally at the light emission parts 2A, 2B, so that the LEDs 21A and LEDs 21B are arranged at wider intervals respectively.
