摘要： A projection display which is light in weight, small in size and can be put into practical use and in which light emitting devices having organic EL elements are employed. Particularly, the deterioration of the light emitting performance which is caused by heat is suppressed, the operation life is prolonged, the luminance is stabilized, and the highest luminance is constantly maintained. The projection display comprises crystal panels (12R - 12B), light emitting devices (13R - 13B) which are provided behind the liquid crystal panels and have organic EL elements as light emitting layers and cooling elements (14R - 14B) which are provided behind the light emitting devices to dissipate the heat generated by the light emitting layers. The cooling elements (14R - 14B) are, for instance, electronic cooling devices utilizing the Peltier effect by which the generated heat is absorbed and dissipated. Alternatively, the cooling elements may be heat dissipating fins by which the generated heat is guided and dissipated.

摘要： Ridges (312) are formed on the surface of a light guide body (311) at regular intervals. Except the sides (312b-1, 312b-2) of the ridges (312), a total reflection layer (313) is formed. A light-emitting means (322) is disposed on one end surface of a light guide means (307), and most of the emitted light enters the interior of the light guide body (311) through a surface of incidence (315). The light from the light emitting means (322) is propagated through the light guide body (311) and goes out from the side surfaces (312b-2). The internal light (305) passes through an optical axis conversion means (321) and then enters an object (302) to be illuminated substantially perpendicularly. The external light (306) passes through the object (302) and then enters an illuminator (303). The light further passes through the optical axis conversion means (321) in the illuminator (303), and is then reflected from the total reflection layer (313). The reflected light passes the optical axis conversion means (321) again perpendicularly and then enters the object (302) perpendicularly. The light further passes through the object (302) to enable the object to be recognized. The light is reflected by the total reflection layer (313) without any loss. In addition, even when the external light (306) enters the illuminator at an angle other than a right angle, it is reflected by the total reflection layer (313) without any loss and enters the object (302).

摘要： A focus detecting mechanism wherein the light reflected on an object surface (25) is diffracted by a hologram element (23). The diffracted light includes two astigmatic convergent beams which form least circles of confusion on long photodetector means (29) and (30) in the same plane close to a focal plane (22f) of a lens (22), and a focus signal is obtained on the basis of a differential output from these photodetecting means. Since two diffracted beams having least circles of confusion on the same plane, the photodetecting means can be placed horizontally, and a focus detecting mechanism can be made easily with an improved dimensional accuracy. In spite of the use of a hologram element, the fluctuation of wavelength can be absorbed, and the reliability of the device is very high.

摘要： A front-placed surface illuminating device which has a high visibility both while illuminating and while not illuminating, and whose power consumption is small. The illuminating device which is placed in front of an object has a light guide plate which is a transparent flat plate and has dot-like light taking-out structures on the surface or at positions facing the surface and a light source facing to an edge of the light guide plate. The light source is, for instance, a point light source. The light taking-out structures are, for instance, column-shaped protrusions and are arranged two-dimensionally. When the illuminating device is placed in front of an object, light is projected to the object and, at the same time, light reflected by the object can be transmitted through the device with almost no diffusion. When the illuminating device is not operated, external light reflected by the object can be transmitted by the illuminating device with almost no diffusion. The point light source may be an LED or a light bulb. The low power consumption can be achieved easily.

摘要： A multifocal lens (10) for eyeglasses, provided with portions of different indexes, such as for far vision and near vision. The multifocal lens is given a predetermined degree of addition Add by making the difference between an average refractive index D11 of the far vision portion (11) and an average refractive index D12 of the near vision portion (12) on the outside (2) of the lens numerically smaller than the degree of addition Add, and by adjusting an average refractive index D21 of the far vision portion and an average refractive index D22 of the near vision portion on the inside (3). The average refractive indexes D11 and D12 of the outside (2) can be so adjusted as to reduce the difference in magnification between the portions for far vision and near vision. The difference between the average refractive indexes D11 and D12 of the outside (2) can also be reduced. Thus, it is possible to provide a multifocal lens which has less image fluctuation or distortion, as might otherwise be caused by the magnification difference, and which can provide comfort with improved astigmatism, widen a range of distinct vision and reduce the image fluctuation.
