License Plate Illuminator

摘要

An apparatus and a method for illuminating a license plate comprising a plurality of infrared emitting devices connected in series, parallel or combination thereof mounted on a core material or substrate in a frame. The apparatus emits infrared light in a wavelength responsive to cameras, security camera, road camera, video-photo-radar traffic camera and others. The infrared emitting device is positioned within the perimeter of the license plate. The apparatus is powered by the vehicle power system or a rechargeable power supply.

1. A method of using illumination provided by a license plate illuminator,
said illuminator comprising a housing; a license plate mounted on the housing; a back enclosure; a core material having a first and second sides that are opposite to each other and one or more side faces defining the thickness of the core material; said material interposed between the housing and back enclosure; an infrared emitting source; said infrared emitting source comprising at least one or more, or optionally a plurality of infrared emitting device (IRED) which generates infrared wavelength which are non luminaire to the human eye but luminous and sensitively responsive to surveillance cameras; said source arranged or positioned along one or more sides of the core material; or optionally mounted longitudinally, surrounding said core material; at least one or more electronic circuits or boards on the core material; wherein the infrared emitting source is one of a plurality of infrared emitting sources comprising at least one or more, or optionally a plurality of infrared emitting device (IRED), said IRED selected from the group consisting of surface mounted IREDs or legged IREDs; said infrared emitting device generates an infrared wavelength of about 450 nm to about 990 nm; said method comprising the steps of: a) monitoring said license plate having mounted infrared emitting source as a means of illumination; wherein the infrared emitting source is one of a plurality of infrared emitting sources comprising at least one or more, or optionally a plurality of infrared emitting devices (IREDs), said IREDs selected from the group consisting of surface mounted IREDs or legged IREDs; said infrared wavelength of about 450 nm to about 990 nm are non luminaire to the human eye but luminous and sensitively responsive to surveillance cameras; said infrared emitting source projects infrared beam in a direction substantially within the license plate of the vehicle; and b) reading the license plate without flaring bright light at the license plate, when the vehicle engine is on park mode, waiting mode and running mode.
