Embodiment Construction

[0033] figure 1 Shown is an LED light strip 100 for a channel sign according to an embodiment of the present invention. The LED light strip includes a flexible circuit board (FCB) 101 having a strip shape and a plurality of LEDs 102 assembled thereto. The purpose of the FCB 101 is to electrically connect the LED 102 mounted thereto so that current can be supplied to the LED 102 . The FCB 101 is flexible such that the LED strip 100 can be adjusted to the shape of a channel sign, ie, curved surfaces and corners. LED 102 may be of any type suitable for mounting to an FCB, such as a surface mount device. Multiple LEDs fitted to a FCB may be of the same type or of different types, eg, be of different sizes or emit light of different colors or intensities.

[0034]The LED light strip 100 further includes an electrical connector (or connection device) 103 for connecting the LED light strip 100 to a power source, so that current can pass through the LED 102 . The connector 103 may...

Abstract

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.

Description

technical field [0001] The present invention relates to LED light strips for channel sign lighting used in illuminated displays for shops and advertisements. Background technique [0002] Illuminated channel signs are commonly used in advertising. Such signs are used by shops and shops for example to advertise their brand name or trademark logo to customers. Due to the wide variety of fonts used for such signs and the unique characters of such signs, they are often custom made. In the past, neon tube lamps were frequently used, but in recent years arrangements based on light emitting diodes (LEDs) have become more and more popular. [0003] Neon tube lights have a number of disadvantages which make them more expensive to use. For example, their shape needs to be customized, thus increasing their price, and thus also the price of the channel signs. Furthermore, neon tube lamps are very fragile and therefore difficult to transport. Furthermore, the need to install and ele...
