[Purpose] To provide a surface illumination fixture using a point light source having strong directivity.[Constitution] In the surface illumination fixture 3 including a surface illumination light-source device 6 converting light from a plurality of point light sources 36 having strong directivity into surface illumination and an illumination fixture main body 41, the surface illumination light-source device 6 includes a casing 30 having a flat plate part 35 being used to attach the surface illumination light-source device to the illumination fixture main body, lateral plate parts standing from the flat plate part, and an opening on a surface opposite to the flat plate part, and includes a light-guide reflection plate covering the opening. The flat plate part 35, the lateral plate parts 32 and 33, and the light-guide reflection plate 40 are formed by members having a high light reflectance and a low light transmittance. The light-guide reflection plate 40 is formed to have a lower light reflectance and a higher light transmittance as the distance from the corresponding point light source increases. The illumination fixture main body 41 having attaching means for attachment to a ceiling or a wall.

A light source device is equipped with a highly directional point light source, a light source installation part having a prescribed area where the point light source is installed, and a lateral reflection part that is vertically arranged to a prescribed height from the periphery of the light source installation part. The lateral reflection part is formed with a light-transmitting reflector plate that has a reflection/transmission pattern and is provided with multiple reflection/transmission parts for reflecting and at least partially transmitting light. In the reflection/transmission pattern, multiple virtual radial lines are drawn from the light source to the light-transmitting reflector plate surface at prescribed angles, and for reflection/transmission parts (Di, j) present on the radial lines that are at the same distance from the point light source, the reflectivity and transmissivity are denoted as Re1 and Tr1 when the reflection/transmission part is on a radial line at a narrow viewing angle to the point light source, and when the reflection/transmission part is on a radial line at a wide viewing angle to the point light source, the reflectivity and transmissivity are denoted as Re2 and Tr2. The relationship therebetween is set as follows: Re1>Re2 and Tr1

There is provided a method for designing a corrugated Fermi antenna having a broad-band and circular directivity required for receiving an image by using a wave of millimeter order. As a first step, an inflection point of the Fermi-Dirac function as a taper function of the Fermi antenna is changed so as to set the beam width of plane H to a beam width having a target directivity. After the beam width of the plane H is set to the target value, the aperture width of the Fermi antenna is changed so as to set the beam width of the plane E to a beam width having a target directivity. Thus, by adjusting the beam width values of the planes H and E independently from each other and matching them with the target values, it is possible to design a Fermi-antenna having a broad-band and circular directivity in a short time.
