  • Patent number: 10402610
    Abstract: In one embodiment, a printed LED area comprises a random arrangement of printed LEDs and a wavelength conversion layer. The LED area is embedded in an object to be authenticated, such as a credit card or a casino chip. The object may include a light guide for enabling the generated light to be emitted from any portion of the object. In one embodiment, when the LEDs are energized during authentication of the object, the existence of light emitted by the object is sufficient authentication and/or provides feedback to the user that the object is being detected. For added security, the emitted spectrum vs. intensity and persistence of the wavelength conversion layer is detected and encoded in a first code, then compared to valid codes stored in the database. If there is a match, the object is authenticated.

  • Patent number: 9488325
    Abstract: A light transmitting device is extremely adaptable and provides a great amount of light for a given battery power. A flexible elongated polymeric light transmitting element has first and second ends with at least one LED immediately adjacent (e. g. touching but not embedded in) one or both of the ends so that light is efficiently transmitted from an LED along the light transmitting element. At least one battery powers the LED. A module including a printed circuit board, electrical switch, and the LED and battery, is positioned within a housing having open ends so that one or both ends of the light transmitting element receive light directly from an LED. A number of button batteries, or a rechargeable battery with USB port, may be mounted on the module, and the circuitry of the printed circuit board may include an integrated circuit.

  • Patent number: 9476553
    Abstract: A flashing night light includes: a night light base, a casing mounted to the night light base, a control circuit mounted to the casing and including a control substrate and light-emitting elements, and a light-transmitting unit including first and second light-transmitting plates. The light-emitting elements are controlled by the control substrate to lighten in sequence. Each of the first and second light-transmitting plates has a surface on which a predetermined pattern is formed. The patterns are arranged according to a sequence for desired displaying. The first and second light-transmitting plates include light receiving sections that are arranged to alternate in position and respectively correspond to the light-emitting elements and are fixed to the control substrate. With the light-emitting elements being arranged to lighten in sequence, lights emitting from the light-emitting elements may provide the patterns with an effect of image displaying and achieve a dynamic visual effect.

  • Patent number: 9448411
    Abstract: An optical substrate having a structured surface that enhances brightness and reduces moiré effect. The optical substrate has a three-dimensionally varying, structured light output surface that comprises an irregular prismatic structure. The irregular prismatic structure may be viewed as comprising longitudinal prism blocks or rows thereof, arranged laterally defining peaks and valleys. Adjacent peaks, adjacent valleys, and/or adjacent peak and valley may be parallel or non-parallel, in an orderly, semi-orderly, random, or quasi-random manner. The lateral adjacent peaks, adjacent valleys, and/or adjacent peak and valley are not parallel. The adjacent irregular prism blocks may be irregular longitudinal sections having the same length, or random or quasi-random irregular sections having different lengths. The facets of each prism block may be flat, or curved (convexly and/or concavely).

  • Patent number: 9360613
    Abstract: A planar light source apparatus includes a point light source and a light guide plate shaped like a flat plate with a rectangular shape in a plan view. The light guide plate includes an output surface confronting an opening portion, a pair of second side surfaces opposed to each other, and a hole opening in a non-output surface and formed near one of the first side surfaces at a position where the point light source is to be arranged. Each of the pair of second side surfaces is at least partially configured as a prism whose ridge line extends in a direction perpendicular to the output surface and whose cross-section, when sectioned in a direction parallel to the output surface, has a sawtooth-like shape in which concavity and convexity are repeated. A light of the point light source can be efficiently uniformized in the light guide plate, and thus unevenness of brightness can be prevented.

  • Patent number: 9223352
    Abstract: An electronic device may have a housing. Components such as keys may be mounted in openings in the housing. The housing may include a display housing portion and a base portion that are coupled using hinge structures. The keys may be used to form a keyboard in the base portion of the housing. Sensitive circuitry such as sensitive wireless circuitry may be shielded from electromagnetic interference by shielding the openings with a layer of conductive material. The layer of conductive material may be a metal layer that forms part of a reflector for a backlight structure. The backlight structure may be used to provide backlight for keys in the keyboard. The keyboard may include a support structure having openings through which the backlight passes to reach the keys. The openings may be bridged using conductive paths so that the support structure serves as a radio-frequency shielding structure.

  • Patent number: 9022590
    Abstract: A luminous keyboard device includes plural keys, a light-emitting element, and a light guide plate. By the light guide plate, a light beam emitted by the light-emitting element is guided to the plural keys. The light guide plate includes plural elongated slots and a light-absorbing part. The plural elongated slots are located near a lateral edge of the light guide plate. After the light beam transferred within the light guide plate is transmitted through the elongated slots and departed from the light guide plate, the fraction of the light beam introduced into the lateral edge of the light guide plate is reduced. The light-absorbing part is located at the lateral edge of the light guide plate for absorbing the portion of the light beam which is introduced into the lateral edge of the light guide plate. Consequently, the lateral light leakage of the light guide plate can be avoided.
