Ceci n'est pas une trousse a crayons. My wish was to be able to transfer the lighting setup of my room along with my childhood memories. My school pencil box gave me the appropriate answer. A modernization of my past thus found the latent use of an object already known to me. It is small in size 260x60x39mm made entirely of anodized aluminum which is a light material and serves as a heatsink for the two small RGBW strips it has inside along with a Bluetooth Led Dimer. It can carry rechargeable lithium batteries to be completely autonomous, so the user can carry it anywhere and place it horizontally, vertically, sideways for direct lighting or turned to the wall for indirect lighting. The emitted light passes through a Fresnel filter (the moving lid of the casket) creating patterns that have references to the filament of the incandescent lamp, thus bringing the past to the present. A small red push button switch also functions as a lid stop. Its use can be programmed through the App of the wireless Bluetooth system. It can have up to eight static or moving scenes from combinations of the four colors of the ledtape. Also, this portable lamp can be controlled through smart devices, mobile phones and tablets (Android/iOS). The title of the proposal is a paraphrase from the well-known work of the Belgian surrealist painter Rene Magritte from 1929. Was the pencil casket betrayed by its transformation into a portable lamp or was a way found to return to our lives full of luminous energy? Stephania Eos Fatsea.
