Enhancing Brand Images With Open Faced LED Channel Letters

It's a trend that even singular store is getting large in size due to a big number of items for sale. Such phenomenon has led to an overheated vying in outdoor advertising on sales products. However, if the level of overheating goes extreme, it's hard to expect effectiveness of each advertising. Some special systems to catch customers?eyes are strongly needed. A small-sized hanging sign recently installed at a home appliances store makes a good case of such systems.

Open Faced Channel Letters with LEDs Enhancing Visibility
In September, 2005 the front design of Digital Exciting Anycall's which is the main signboard of the Digital Plaza changed into an open faced channel letters with LEDs. Most of the existing signs at the Digital Plaza stores have been those made of fluorescent and cold-cathode lamps. However as LEDs channel letters have increased since last year, LEDs lighting is applied on the Digital Plaza P.O.P signs in recognition of the trend that LEDs is a newly rising light source.
On the other hand, there has been a tendency that the visibility of certain signs is low because of a good number of sings inside and outside the Digital Plaza shops. Under this circumstance the shop tried to enhance the visibility of Anycall logo which is one of Samsung most representative brands. To gain an outstanding exposure effect from consumers the company needed something effective at straightforwardness than dissemination in advertising. To meet the requirement, LEDs lighting was first considered. At the early stage of planning, the capped type of LEDs channel letter covered with light diffusion sheets was considered, but on the grounds it is short of general spreading effect due to LED unique specification and its radiation effect falls behind, eventually an open faced type of channel letters was chosen.

Different Lighting Application on Each side of Sign
The open faced type of channel letter sign was hung from a ceiling of a shop. LEDs is mounted on the side of the sign facing toward outside, and a white sheet is applied on the side toward inside. At first stage, the use of LEDs was considered on the both sides as well, but the reason white sheets are applied on the side facing toward inside is that excessive lighting may lower visibility and consequently reduce the ad effect as well as the LEDs is very expensive to mount on the both sides.
Recently the increasing number of open faced channel letters has been installed on outer walls of apartment buildings and at shopping malls. The common feature in manufacturing those signs is to use dot matrix plates, which make the external appearance neat. The dot matrix plates are also used to make Anycall hanging signs. Generally, those plates are designed first by a channel company and manufactured by a laser cutting company.

LED Module Intervals Determined by Visibility Range
For LED channel signs it is important to determine an appropriate distance between the LED modules. The distance defines the number of modules, which is directly related to the cost. The LED channel letters in Anycall hanging sign measures 974×320 mm and its module distance is 2.5cm. Its size and module distance has been decided in the consideration of not only pedestrians on sidewalks but also cars on roads and the sight of pedestrians on the other side뭩 sidewalk. To achieve the most effective signs within approximately 10m, the module distance should be about 2~3cm.
If an interval between modules goes away within a close visibility range, it hard to read each letters because they look blurred. However, in case of channel letter with LEDs is seen from long distance like channel letters on outer walls of apartment buildings modules could be mounted at 10cm interval. One hundred sixty five modules are used in the letters of nycall?at this shop, while the number of modules has been raised to 553 at another shop opened last September. The change was made not to make up for low visibility due to weak lights but for the beauty of the signs.
