摘要： In a transparent and spread illuminating apparatus 1, a light reflection pattern 7 consisting of the concave and convex is formed on the front surface 6 of a transparent substrate 2 so that the emission light is allowed to be uniformly irradiated on the face of the transparent substrate 2 regardless of a distance from a light source lamp 4, and the light is facially irradiated on a reflection type liquid crystal display element L. In addition, a transparent member 11 for changing the progressing direction of the light reflected from the transparent substrate 2 is disposed between the reflection type liquid crystal display element L and the transparent substrate 2 so as to be in close contact with both surfaces thereof. As a result, the degradation of the contrast which makes the observation of an image difficult and the generation of the moire pattern can be prevented.

摘要： A spread illuminating apparatus provides a uniform illuminance, an accurate illumination, an improved visibility, and an expanded screen size. Light sources (5a, 5b) comprising bar-like light conductive members (3a, 3b) and spot-like light sources (4a, 4b), respectively, are disposed close to end surfaces (8a, 8b) of a transparent substrate (2). A light reflection pattern (29) is formed on a surface of the transparent substrate (2) along the length of the light conductive members (3a, 3b). The light reflection pattern (29) comprises grooves (27) and flat portions (28) adjacent to the grooves. The grooves (27) are shaped trapezoidal in section, and the depth thereof increases in proportion to the increase in distance from the light sources (5a, 5b) and measures maximum at the center of the transparent substrate (2).

摘要： A spread illuminating apparatus includes a light conductive plate provided with a light entry face at its corner, having a spot-like light source disposed close to or in contact with the light entry face, and having a light reflection pattern formed on its major surface. The light reflection pattern comprises a plurality of arced grooves and is configured such that the grooves have their depths increasing with an increase in the distance from the light source, and that each of the grooves has its depth increasing with an increase in the light emission angle made by a line of a light emission direction with respect to a diagonal line from the light source. Thus, the light reflection pattern is adapted to reflect more light at an area farther from the light source and the diagonal line as well, thereby further improving uniformity in brightness all over the light conductive plate.

摘要： A spread illuminating apparatus 1 according to the present invention includes a transparent substrate, a linear light source made up of a light reflector 16 as an optical path conversion portion and/or a light conductor 13 made of a linear transparent material and having optical path conversion portion at least, on either side and disposed closely along at least one side end surface 3 of a transparent substrate 2, and a dot-shaped light source 12 disposed on one end portion 14 of the light conductor 13. The light emitted from the dot-shaped light source 12 enters the light conductor 13/or reflected on the light reflector, and the light emitted from a surface 18 opposing to the transparent substrate 2 enters the transparent substrate 2, to thereby become a linear light source as a whole. Accordingly, since a fluorescent lamp which has been employed as a conventional light source is not used, impact resistance is improved, and illumination is enabled at a low voltage.

摘要： There is provided a spread illuminating apparatus to suppress the appearance of moiré fringes. A light reflection pattern of a transparent substrate is composed of grooves of substantially triangular in section and flat portions adjacent thereto. The light reflection pattern is formed substantially parallel to the optical axis of a bar-like light source and the depth of the grooves increases gradually in proportion to the increase in distance from the light source. The interval of the adjacent grooves (the groove interval) is set to vary irregularly. Thereby, the relation between the interval of grooves and the interval of mosaic pattern of liquid crystal cells is not definite, and the appearance of moiré pattern can be suppressed. The variation ratio of the groove interval is set to range 25% to 85% of the average groove interval

摘要： A plurality of minute lenticular elements made of a light-transmissible material and each having a substantially plano-convex cross section are formed on a major surface of a light conductive plate opposite to another major surface provided with a light reflection pattern, and are arranged radially with respect to a spot-like light source with their respective longitudinal directions oriented perpendicular to grooves of the light reflection pattern. Light rays guided in the lenticular element from its bottom surfaces are spread in a circumferential direction of its outer curved surfaces. A view field angle can be increased by the lenticular element in a direction tangential to the grooves improving view field angle distribution.

摘要： The present invention provides a spread illuminating apparatus for improving the machinability and durability of a molding die for a transparent substrate and obtaining an excellent light reflection. In a light reflection pattern comprising grooves and substantially flat portions adjacent to the grooves and formed on an upper surface of the transparent substrate in parallel to the optical axis of a bar-like light conductive member located close to an end surface of the transparent substrate, the grooves are each formed substantially trapezoidal in section with their bottom surface defining a shorter side of trapezoid. The inclination angle of an inclined surface positioned closer to a light source is set to range between 35° and 55°, the inclination angles of both the substantially flat portions and the bottom surfaces are set to range between −5° and +5°, the width of the substantially flat portions is set to be constant, and the width and depth of the grooves gradually increase in proportion to the increase in distance from the light source.

摘要： There is provided a spread illuminating apparatus to suppress leakage of light. Light emitted from a light source, reaching a first inclined surface of grooves of a light reflection pattern and exiting out there is caught by a second inclined surface thereof at an area positioned above the first inclined surface since the distance between an upper edge of the second inclined surface and the level of a bottom thereof is set greater than the distance between an upper edge of the first inclined surface and the level of the bottom thereof. Thus, light, which will leak in case of a conventional art, can reenter a transparent substrate at the second inclined surface so as to improve illumination efficiency.
