Ban­ga­lore-based Di­a­mond Sig­nages has tied up with Tai­wan-based DD Flex, one of two com­pa­nies in the world to have pi­o­neered solid acrylic LED let­ters -- the other company is LP Flex from Ger­many), to pro­duce su­pe­rior qual­ity 3D let­ters with LEDs em­bed­ded in them. The ad­van­tage of this prod­uct is that it is man­u­fac­tured as a sin­gle piece with no joints seen. With the tie-up, Di­a­mond Sig­nage has bought ma­chines to man­u­fac­ture the let­ters. The en­tire process is sim­ple and works on the soft­ware pro­vided by DD Flex. “Spe­cial acrylic has to be used for th­ese let­ters. With nor­mal acrylic, LEDs will be seen as spots when switched on. We tried pro­duc­ing the acrylic which would match up to DD Flex, but it was not pos­si­ble,” says Venkatesh R G, Man­ag­ing Di­rec­tor, Di­a­mond Sig­nages. How is the let­ter made, one may ask. Here, there is no chan­nel of 3D box mak­ing in­volved. A sin­gle piece of 25mm or 30mm acrylic is taken in which LEDs are em­bed­ded and sealed with epoxy resin which makes it a ho­moge­nous ma­te­rial. The acrylic as well the LEDs are bought from deal­ers sug­gested by DD Flex. The big­gest ad­van­tage of th­ese let­ters is that since it forms as a sin­gle piece, no dust or wa­ter can seep in, thereby in­creas­ing the life of the let­ters. In case an LED fails, the en­tire let­ter is re­placed. Also, usu­ally 3D let­ters face a prob­lem of get­ting heated up due to the LEDs. Here, the epoxy resin dis­si­pates the heat and the let­ters re­main at room tem­per­a­ture. When we talk of the cost for such a qual­ity based prod­uct, it is bound to be ex­pen­sive. “The cost would be about 20 per cent higher than the best qual­ity of di­men­sional let­ters we pro­duce here. But at the same time for that 20 per cent ex­tra, the cus­tomer gets bet­ter qual­ity and longer last­ing let­ters. We will be able to bring down the cost by about 5-6 per cent in the near fu­ture when we can im­port more raw ma­te­ri­als in one ship­ment,” says Venkatesh. An added fea­ture of th­ese let­ters is that they have cham­fered edges. The LEDs need a mar­gin and the wall thick­ness of the acrylic has to be ac­counted for. The cham­fered edges as­sure even light­ing when seen from out­side. Also, the cham­fered edges are eas­ier to clean. Talk­ing about the business re­la­tions, Venkatesh says, “We share very cor­dial re­la­tions. Once we have paid them their tech­ni­cal fee, they are more than happy to as­sist us in ev­ery way. Their name in the coun­try mat­ters more. Also, they will hap­pily share their fu­ture R&D de­vel­op­ments with us.” Di­a­mond Sig­nages is work­ing with Croma as of now for this new tech­nol­ogy of 3D let­ters. Be­ing very new yet, they are still pitch­ing to other com­pa­nies.
