摘要： A passive-type moving object detection system is disclosed. The system includes an infrared detector, infrared sensors mounted on the infrared detector, a detection field including two columns of detection regions for monitoring a human intruder and two rows of detection regions for detecting a non-human intruder. The columns have a height corresponding to a human height, and an optical system is located between the infrared detector and the detection field. The infrared sensors have infrared accepting areas that include first and second sections. The first section optically corresponds to the columns and the second section optically corresponds to the rows. Each sensor receives infrared radiation from a moving object passing through the detection regions. The detector includes an arithmetic circuit that subtracts the peak values of signals generated by the detector and a decision circuit to compare the result with a reference level.

摘要： A surface light source device is provided with a primary light source and light guide plate. The light guide plate has an incidence side face opposite to which the primary light source employing LEDs or the like is disposed, an emission face for emitting light, which has been incident to the incidence side face, during the propagation process, and a back face oppositely located with respect to the emission face. The back face may be provided with a plurality of prism projections running generally vertically to the incidence side face. The primary light source has an effective light emitting surface provided with length L in a thickness direction of the light guide plate, which is not smaller than thickness t of the light guide plate at the incidence side face. This causes primary light to be incident to the incidence side face as to cover from an upper edge to lower edge thereof, preventing dark parts from being generated. As a result, the emission face comes to avoid stripe-like uneven brightness from appearing thereon.

摘要： Primary light is directed to a light path control plate from at least one point-like light source. The light path control plate has an inner face on which projection-like transmission-reflection portions and curved-for-refraction portions are alternately formed along a leaving-direction from an optical axis direction of the point-like light source, wherein each transmission-reflection portion is composed of a transmission face permitting primary light to transmit through the transmission face and a reflection face which reflects the transmitted light as to bring changed light paths directed to an outer face of the light path control plate while each curved-for-refraction portion refracts primary light as to bring changed light paths directed to the outer face of the light path control plate. First light reaching the outer face via the transmission-reflection portions and second light reaching the outer face via the curved-for-refraction portions are generated from primary light. The first light and second light are emitted from the outer face. A plurality of sections each of which is equivalent to the above light path control plate may be formed on substrate for providing illumination for a large screen display.

摘要： A LCD panel LP of LCD 2 is illuminated by a surface light source device of side light type 1 for backlighting. The surface light source device 1 comprises a plurality of sets each of which consists of a primary light source and a guide plate. When a fluorescent lamp 11A is turned on, illumination light LA is introduced into the guide plate 7A and then emitted from an emission face 7AO to be transferred to another guide plate 7B. A back face 7AR is provided with projection rows which prevent illumination light from being diverged toward right and left directions as viewed from an incidence end face 7A. Light transferred to the guide plate 7B is emitted from an emission face 7BO to directions inclined forward (LA1). A prism sheet 9 converts this into output illumination light LA2, which illuminates the LCD panel LP through a light diffusion sheet 10. When another fluorescent lamp 11B is turned on, illumination light LB is introduced into the guide plate 7B and then emitted from the emission face 7BO to directions inclined forward (LB1). The prism sheet 9 converts this into output illumination light LB2, which illuminates the LCD panel LP through the light diffusion sheet 10. A driving circuit 4 provides driving current control (including optional on/off control) for the fluorescent lamps 11A, 11B. Diverse directivity characteristics are realized depending on inclination angles of prismatic slopes of the prism sheet disposed along the emission face 7BO. For instance, optional output to one or both of different two directions.

摘要： Provided is a light guide plate having a simple structure that allows an effective emission area to be large and shows a reduced unevenness in brightness in an emission region near to an incidence side face as well as a reduced dropping in brightness in an emission region remote from the incidence side face. The light guide plate is used to provides a surface light source device and an image display employing the device for illuminating an image display panel. In the incidence side face of the light guide plate, a generally central region is formed of a high light dispersing ability area (rough area). The high light dispersing ability area is sandwiched by low light dispersing ability areas (flat and smooth areas or rough areas having a small surface roughness). The high light dispersing ability area is formed in a range including a region irradiated by a center LED of three LEDs.

摘要： A surface light source device of side light type is provided with a guide plate, a primary light source, a reflection sheet, and a prism sheet providing a light control member. An emission surface of the guide plate provides a light control surface (arrow C). The light control surface has a large number of minute projections each of which extends generally orthogonal or slightly obliquely to an incidence surface. Each projection has a pair of slopes. A surface of a light control member (prism sheet) is opposite with the guide plate to provide another light control surface (arrow D). Projections on the light control member extend generally in parallel with the incidence surface of the guide plate and each have first and second slopes which are relatively remote from and relatively near to the incidence surface, respectively. Inclination angle .beta.2 of the second slope (as defined with respect to a normal erected on a general surface of the guide plate) is small compared with inclination angle .beta.1 of the first slope. Inclination angle .beta.2 may be smaller than, for example, 40-degrees. A light diffusion member may be disposed between the emission surface of the guide plate and the light control member.

摘要： Provided are an illumination device and a lens employed in the device for controlling light travelling direction, the device being capable of illuminating brightly and uniformly a certain limited region (region-to-be-illuminated) corresponding to an object such as subject for photography. The illumination device emits light H coming from a light emitting element (point-like light source) employing a LED as a light emitting source via the lens. A light control emission face of the lens emits light (rays), which is included in light H introduced into the lens through an incidence face thereof and travelling within the lens to the light control emission face without undergoing inner-reflection at any surface of the light control emission face, as illumination light. The light control emission face is configured so that no set of rays included in the illumination light make any crossover at least before reaching a region-to-be-illuminated and rays within a direction range near to a direction of optical axis L have lower light flux density as compared with that in the outside of the direction range.
