CONSTITUTION:A bar code 2 is irradiated with light from the light source 1 of a thin film EL element, and the optical path of reflected light from the bar code 2 is changed by a mirror 3, and it is converged on a lens 4, and is received by the light receiving element 5 such as a charge storage element (CCD), and it is converted to an electrical signal, then, information stored in the bar code is read by a decoder circuit. The thin film EL element is as follows. (1) An EL element whose surface confronting with an information display medium is formed in a curved surface with the center formed in recessed shape. (2) An EL element in which the film thickness of an EL element light emitting layer is thickened at both terminal parts of the element. (3) An EL element whose EL element light emitting surface is widened at both terminal parts of the element. (4) An EL element letting EL element light emitting surface be plural number and in which the total area of the light emitting surface is formed larger than a middle part at both terminal parts of the element.

摘要： PURPOSE:To provide an information reader such as a bar code reader for reducing reading error. CONSTITUTION:A bar code 2 is irradiated with light from a light source 1 of a thin film EL element, reflected light from the bar code 2 is converged by a lens 4 while changing the optical path with a mirror 3, received by a light receiving element 5 such as a charge coupling device(CCD) and converted to an electric signal, and information stored in the bar code is read by a decode circuit. As the thin film EL element, any element of which emission spectrum has plural peaks is used. Thus, even when the information display part of an information display medium and a base show the same reflection luminance at one peak wavelength of an EL light source, the light receiving element can identify the optical information on the information display medium by the other peak wavelength which can generate difference in the reflection luminance.

摘要： PURPOSE: To produce a color filter capable of forming a picture element eliminating a peeling from a substrate in a producing method for color filter forming a black matrix, R, G and B picture elements on a transparent substrate by exposing the rear side of the substrate at a colored picture element forming stage. CONSTITUTION: A red photosensitive resin layer is laminated on a glass substrate 2 on which a black matrix 1 of a Cr thin film has been formed previously by using a red dry film in which a colored photosensitive resin soln. consisting of a prescribed composition is made into film. Then, after executing registration by using a negative mask having a prescribed pattern, exposure is executed from the surface side of the substrate with a 3KW-super high voltage mercury vapor lamp, then, an unexposed part is removed to form a colored pattern of the first color. The second color is formed by using a blue dry film in the same manner. Moreover, after laminating green dry film, the exposure is executed from the rear side of the substrate without interposing the mask. Then, a similar development up to the second color is executed to form the picture of the third color.

摘要： PURPOSE:To provide a comfortable lighting system capable of varying color temperature without decreasing color rendering properties of a fluorescent lamp. CONSTITUTION:A lighting system is constituted by arranging a fluorescent lamp 1, an EL part reflecting film 2, and a transparent thin film EL emitting element 3 in order. By superimposing the emission from the fluorescent lamp 1 on the emission from the transparent thin film EL emitting element 3, light mixing lighting is performed by operating mainly the transparent thin EL emitting element 3. By simple lighting operation, light mixing illumination from white color to incandescent lamp color specified in JIS, for example, can be obtained without decreasing color rendering properties. Particularly, light mixing ratio and light color can be varied in accordance with the atmospheric environment such as temperature and humidity.

摘要： PURPOSE:To drive a capacitive emitter at low d.c. power source voltage, and to reduce consumption power by connecting a drive circuit consisting of two coils and at least two switches, to an EL element, and by specifically controlling the ON/OFF operation of the switch. CONSTITUTION:A first switch means S1 is turned into ON condition from an OFF condition, and power is accumulated in a first inductor means L1, and the S1 is turned into OFF condition after a specific period of time passes, and the power of L1 is fed to and charged in a capacitive emitter EL. A process of accumulating the charged power of the emitter EL in a second inductor means L2, and a process of carrying out the same control for a second switch means S2 and for the circuit of the L2, to accumulate the charged power of the emitter EL in the L1, are also included. The two processes are repeated alternately or in partially the same time, by a controller. The power source voltage can be low, since part of the power accumulated in the emitter EL is returned to the L2, L1, and is re-used, and the power can thus be used effectively.
