An LCD is provided, by which damage to an irradiating tube can be prevented, and the unevenness of light in a display section can be reduced. In the LCD, the display section and the light-generating section are detachably attached to each other. Elastic members for supporting the irradiating tube are provided in the light-generating section in a tightly contacting manner, and a light-transmitting member for transmitting the light from the irradiating tube is positioned at the light-emitting side of the light-generating section.

A vehicle lamp fixture is disclosed in which a truncated bowl-shaped reflector 6 is formed as a single unit in front of each respective LED 5. Each reflector is formed from a transparent substance and has an aperture in the front surface. Each reflector also has a reflective surface 6b that totally reflects light from the LED 5 and a light conductive member 6c that conducts at least a portion of light reflected by the reflective surface toward the front of the light fixture. A transparent front lens can thereby be used that does not include light-distributing facets.

A resin sheet having laminated transparent resin layers and a smooth outer surface, the refractive indexes of two resins of any adjacent two resin layers differing from each other, the interfaces among the resin layers having an uneven shape, is produced with an extrusion molding apparatus having such a structure that a plurality of transparent resins are extruded from respective separate flow passages into a composite resin flow passage to form a composite resin flow having a laminate structure with an uneven shape at the interfaces of the resin layers, and that the composite resin flow is extruded from an outlet of the composite resin flow passage. The resin sheet is used as a laminate, or a light guide of a surface light source element.

A light source arrangement for a battery-powered light source unit of an endoscope comprises a cylindrical housing, a base disposed at one end of the housing, a plurality of LEDs connected to a flexible circuit board supported on the base and a focusing lens. A light guide for directing light emanating from the LEDs. The light guide comprises a reflective surface formed on an inner wall of the housing, a reflector having a concave reflective surface which is disposed at one end of the housing so as to surround the LEDs or a micro-lens array disposed in front of the LEDs with each micro lens aligned with the LED.

An illuminating fire hose includes a fire hose having a first end, a second end, an interior wall and an exterior wall remote from the interior wall. The fire hose has at least light emitting element exposed at the exterior surface of the fire hose for selectively emanating light. The light emitting element is preferably attached to the exterior surface of the fire hose using an adhesive or securing threads for sewing the light emitting element to the exterior surface of the hose. The light emitting element may include a fiber optic cable, a chemiluminescent cable or a series of light emitting diodes. The light emitting element is activated during a fire to provide fire fighters with a visible marker that may be seen in a darkened and/or smoke-filled enclosure.

An electronic lighting device for use as a signal or illuminator. Light is created by a light emitting diode element which is encapsulated in a light transmitting medium. A curved exterior lens with a first radius of curvature is a first reference plane and a second and smaller radius of curvature in a normal plane cooperates with the location of the light emitting diode element to create a light beam with a controlled beam pattern which is elongated in a defined or first reference plane. The intensity of the projected light beam is maximized through the efficient collection of created light.

A lighting apparatus includes a lens, such as a circular rod carried by a housing. A lamp or light is positioned adjacent the circular rod which has a convex entry portion and a convex exit portion to distribute a wide and intense beam of light to a desired area. Variations of the apparatus allow for distribution of the light in any desired pattern, either downwardly or outwardly, as desired by the particular end use. The apparatus eliminates the need for reflectors to assist in generating the beam, although mirrors may be employed to generate a triple high-intensity beam from a single light source.

A side mirror cover for allowing flickering or illumination of lamps to be visible from relatively a wide range is provided. The side mirror cover has a mirror cover body and a cover lamp. The lamp has a lamp housing having plural light emitting elements and a translucent lamp cover for covering the elements. The housing has a curved first corner section for closing up a part of the through hole and a first principal portion for closing up the remainder thereof. The lamp cover has a second corner section facing the first corner section and a second principal portion facing the first principal portion. The light emitting elements include first LEDs and second LEDs for emitting light toward the front and the side of the vehicle, respectively. The inner surface of the lamp cover has a projected portion facing the second LED, and the inner surface of the second corner section has concavities and convexities for reflecting light.
摘要:
The invention relates to an illuminating or indicating device for a motor vehicle, including a housing forming a support for at least one light source combined with at least one reflecting surface in order to form an illuminating or indicating beam, enclosing glazing being arranged in front of the light source, and a mask being arranged between the housing and the enclosing glazing in neutral regions of the illuminating or indicating device. According to the invention, only the reflecting surface intended to form an illuminating or indicating beam is metallised or metallic, and the mask is made of transparent material.
