    摘要: A light source module adapted for a signboard having a light emitting surface is provided. The light source module includes a base, at least one light source, at least one first reflective structure, and at least three second reflective structures. The base has a bottom and at least one side surface. The side surface is adjacent to the bottom and disposed between the bottom and the light emitting surface. The first reflective structure is adjacent to the side surface and far away from the bottom. The second reflective structures are disposed on the bottom. Part of the light beams provided by the light source ejects from the light emitting surface after reflected by one of the second reflective structures. Another part of the light beams ejects from the light emitting surface after reflected by the first reflective structure and one of the second reflective structures sequentially.

    摘要: A direct-type LED backlight module includes a supporting base having a supporting face, an LED mounted on the supporting face of the supporting base, and a dome-like light guiding cover positioned on the supporting face of the supporting base and covering the LED. The light guiding cover defines a plurality of through holes for permitting light emitted from the LED to pass through light guiding cover. The through holes are spaced from each other and arranged in a number of imaginary concentric circles relative to a center of the light guiding cover. An inner face of the light guiding cover facing the LED is coated with a reflective film. A semispherical light reflecting portion protrudes downwardly from an inner face of a top portion of the light guiding cover towards the LED.

    摘要: The disclosure relates to an advertising lightbox including a source of background lighting for a transparent or translucent panel, which includes advertisement indicia and/or graphics. The background light source includes an LED array that extends along a longitudinal axis. The light source also includes a reflector having a plurality of planar sections elongated substantially parallel with the longitudinal axis of the LED array. The elongated planar sections of the reflector are positioned on both sides of the LED array at different offset positions along a lateral axis, and are inclined at different angles of inclination in a positive vertical axis towards the panel. The desired illumination effect upon the advertisement panel depends on the type or characteristics of the LED array, the parameters (number of sections, angles of inclination, height, width, reflective material, etc.) of the reflector, and the distance between the panel and the LED array.

    摘要: A display device includes at least one wall with transparent areas and a reflecting object arranged inside the display device and oriented so as to receive an incident external light and to redirect a reflected light onto the transparent areas. The transparent areas are provided in different planes and the reflecting object includes several reflecting surfaces or a non-planar reflecting surface to reflect incident light rays on each of the transparent areas along different reflection axes. The display device can advantageously be integrated into a bottle or a bottle cap.

    摘要: An “extra-folded” projection display system includes a selectively reflective material (e.g., a linear reflecting polarizer) placed immediately behind the system's imaging screen. The display system includes an image projector that projects an image beam containing light of a predetermined linear polarization toward the imaging screen. The linear reflecting polarizer reflects the light in the image beam away from the screen. The reflected image beam then encounters a ¼-wavelength achromatic retarder which converts the linear polarization to circular polarization. The image beam next hits a mirror that reflects the light back through the ¼-wavelength achromatic retarder, which converts the circular polarization back to linear polarization, with the polarization director rotated 90° from the original polarization director. The linear reflecting polarizer then allows the light to pass through to the image screen.

    摘要: A method of designing an illuminated grid sign designed to be viewed at a maximum viewing angle (&agr;) from a horizontal line of sight of an observer. The method comprises selecting the maximum viewing angle (&agr;), selecting the illuminated tubing with inside radius (r), determining the minimum distance (d) between the tubing and the reflective channel, and designing the substantially semi-cylindrical reflective channels to have a radius (R) approximately equal to 80% to 120% of r×(1+1/(sin &agr;))+d and an angle of wrap (&bgr;) no greater than about 180°. The design method provides a sign that minimizes visible streaks of brighter and less-bright illuminated regions in the sign when viewed from an angle less than or equal to the maximum viewing angle (&agr;).
