Принадлежит: KONINKLIJKE PHILIPS ELECTRONICS NV

A light emitting diode, LED, strip ( 301 ) for the illumination of channel signs is provided. The LED strip comprises a flexible circuit board, a plurality of LEDs mounted on the circuit board, and an electrical connector for connecting the LED strip to a power supply. The LED strip is at least in part encapsulated by a flexible resin such that the LED strip is foldable. The LED strip according to the present invention is advantageous in that its length can be adjusted by folding instead of cutting, thereby retaining the waterproof encapsulation of the LED strip. Further, a method for mounting a flexible LED strip ( 301 ) in a channel sign is provided. The method comprises the steps of attaching at least one clip ( 302 ) to an interior surface ( 303 ) of the channel sign, folding back an end ( 304 ) of the LED strip, and fixating the LED strip including the folded end using the clip. The method according to the present invention is advantageous in that it provides an easier and more reliable mounting of a LED strip as compared to standard prior art techniques.

Принадлежит: Александр Александрович Селиванов

Полезная модель относится к области наружной рекламы и может быть использована при изготовлении коробов, используемых в качестве систем навигации, указателей, рекламных и информационных стендах, рекламных носителей, информационных табло с использованием светодиодных модулей и т.п. Полезная модель направлена на упрощение монтажа и демонтажа устройства с возможностью герметичного соединения профиля без дополнительного крепежа и инструмента, что достигается за счет того, что самонесущий профиль для изготовления рекламно-информационного короба включает в себя полые профили, которые легко соединяются между собой с помощью соединительных уголков. Каждый профиль состоит из двух секций 1, 2. Первая секция 1 и вторая секция 2 соединены внахлест и имеют общую первую грань 8, формируя единую деталь профиля со ступенью - вторым монтажным выступом 7, образованным за счет разности высоты секций 1, 2. Первая секция 1 представляет собой полый прямоугольный параллелепипед, имеющий до 3-х ребер жесткости 3 в зависимости от планируемой нагрузки. Секция 2 имеет форму многоугольника и выполнена с высотой больше высоты первой секции 1, образуя ступень - второй монтажный выступ 7. Верхняя грань 10 второй секции 2 имеет продольный паз 5 для крепления защитного стекла. Вершина 4 образованная верхней гранью 10 второй секции 2 и первой боковой гранью 11 второй секции 2 скошена. Вторая боковая грань 9 является монтажной поверхностью. Нижняя грань 15 по высоте выступает над второй боковой гранью 9 первой секции, образуя первый монтажный выступ 6, который служит для упора задней стенки конструкции рекламно-информационного короба. Уголок выполнен в виде полой детали с двумя правыми выступами 12 и двумя левыми выступами 16 для первой секции 1, одним правым выступом уголка 13 и одним левым выступом 17 для второй секции 3. Правые 12, 13 и левые 16, 17 выступы выполнены под прямым углом относительно друг друга. Правая боковая поверхность уголка 19 и левая боковая поверхность 20 уголка по высоте ...
