摘要:
A photo-catalyzer for deodorizing, cleaning, sterilizing, and water purifying operations includes a substrate, a titanium dioxide film disposed on the substrate and functioning as a photo-catalyst, and a light-emitting diode disposed adjacent to the titanium dioxide film and producing ultraviolet light having a wavelength from 360 to 400 nm onto the titanium dioxide film. The photo-catalyzer can be used in places where there is no sunlight because it is optionally provided with a light-emitting diode. The light-emitting diode does not require a large installation space because it is an extremely small light-emitting device. Hence, the photo-catalyzer has a compact structure and can be used easily anywhere, including small places. The substrate can be fabricated into a variety of useful appliances to take advantage of the strong oxidizing properties of the photo-catalyzer. Devices comprising a photo-catalyzer may be used for deodorizing, destroying or repelling micro-organisms, and including undertaking air or water purification.

An LED display device has an indicator having a housing. The housing has at least one incident portion which receives light from at least one LED. The incident portion has a reflection surface at its inside surface. LEDs emit light from one side or one longitudinal end of the incident portion. A refraction plate may be provided to direct emission of the incident light for viewing by a user.

A planar light emitting device has a planar light emitter. It has a layered structure composed of a transparent body and a semi-transparent body. The transparent body is made of a transparent synthetic resin containing no light scattering material. The semi-transparent body is made of a semi-transparent synthetic resin containing a light scattering material. The transparent body and the semi-transparent body are joined to form a diffusion layer therebetween. An LED array is disposed at one side of the planar light emitter. The diffusion layer has a sea-islands structure. An island resin has a dimension of 0.1 to 50 microns. The light entering the island resin attenuates therein without reflecting at once due to its complicated shape. Namely, the light entering the diffusion layer generates uniform brightness.

An LED display device having an LED array for a meter on a printed circuit board. A diffusing radiation lens array is disposed facing the LED array. A cover lens is overlapped on the lens array. The cover lens transmits LED light which passed through the lens array. The cover lens has at least a scale mark, a character and a sign. A sheet is interposed between the lens array and the cover lens. The sheet limits radiation of predetermined diffused light from the lens array while partially transmitting the diffused light. The cover lens has a scale mark dent and a character dent formed on its rear interior surface, and displays the scale mark and character by means of an LED light from another LED array.

An information indicating device having an LED and a light transmitting structure is disposed within a line of sight of a vehicle operator so as to transmit light from the LED to the vehicle while the operator is driving the vehicle. A distance sensor measures a distance between a vehicle body and an object near it. An emission control circuit controls the LED based on an output of the distance sensor, thereby indicating predetermined information, such as a distance warning to the operator. An indicating portion is disposed on an end of a corner pole or a fender marker to receive light from the LED and transmit light to the vehicle operator without requiring the vehicle operator to substantially look away from the direction the vehicle is traveling or a mirror showing the driver the vehicle's traveling direction.

A vehicle display device such as a speed meter including indicators, many segments illuminated in two or more colors by plural LEDs and an indicator control circuit. The indicators dispose the segments so as to display a variable such as a car speed in a bar graph or in the form of a number. The indicator control circuit displays the variable by controlling the lighting of the LEDs and changes an emitted light color of indication based on a fixed color changing reference value in accordance with a value of the variable. The control circuit controls a duty ratio of a supply current or a current value in a predetermined set value range determined on the basis of the color changing reference value. Namely, brightness of the emitted light color before a color change is gradually decreased, while brightness of the emitted light color after the color change is gradually increased.
