\u00c9vitez de remplacer une couleur par une couleur \u201c suffisamment proche \u201d propos\u00e9e par un fournisseur sans autorisation<\/li>\n<\/ul>\n\n\n\nV\u00e9rifiez \u00e9galement la r\u00e9glementation locale en mati\u00e8re d'enseignes. Certaines collectivit\u00e9s, certains propri\u00e9taires et certaines autorit\u00e9s charg\u00e9es de l'urbanisme imposent des restrictions concernant les clignotements, les animations, les changements de couleur, la luminosit\u00e9 ou les horaires de fonctionnement. La compatibilit\u00e9 RVB ne donne pas pour autant le droit d'utiliser tous les effets propos\u00e9s par le contr\u00f4leur.<\/p>\n\n\n\n
Un processus de s\u00e9lection des couleurs des n\u00e9ons LED en sept \u00e9tapes<\/h2>\n\n\n\n\u00c9tape 1 : D\u00e9finir la fonction du panneau<\/h3>\n\n\n\n
Cette enseigne sert-elle principalement \u00e0 identifier l'\u00e9tablissement, \u00e0 attirer l'attention, \u00e0 cr\u00e9er une ambiance, \u00e0 guider les visiteurs ou \u00e0 offrir une fonctionnalit\u00e9 li\u00e9e aux r\u00e9seaux sociaux ?<\/p>\n\n\n\n
Un panneau peut remplir plusieurs fonctions, mais l'une d'entre elles doit pr\u00e9valoir.<\/p>\n\n\n\n
\u00c9tape 2 : Recueillir les v\u00e9ritables directives de la marque<\/h3>\n\n\n\n
Demandez les fichiers graphiques vectoriels, les valeurs Pantone, les valeurs HEX, les donn\u00e9es CIELAB, les r\u00e9f\u00e9rences de finition et les photographies des panneaux existants d\u00e9j\u00e0 approuv\u00e9s.<\/p>\n\n\n\n
Ne travaillez pas \u00e0 partir d'un fichier JPEG compress\u00e9 copi\u00e9 depuis un site web.<\/p>\n\n\n\n
\u00c9tape 3 : R\u00e9aliser un audit du site<\/h3>\n\n\n\n
Notez la couleur des murs, la texture des surfaces, l'\u00e9clairage ambiant, les fen\u00eatres, les reflets, la distance d'observation, l'angle d'observation, les horaires d'ouverture et les enseignes voisines.<\/p>\n\n\n\n
\u00c9tape 4 : Choisir le syst\u00e8me d'\u00e9clairage<\/h3>\n\n\n\n
Choisissez entre une couleur fixe, un blanc r\u00e9glable, RVB ou RVBW en fonction du cahier des charges. Choisissez ensuite le profil, le support et le mode de fixation.<\/p>\n\n\n\n
\u00c9tape 5 : R\u00e9alisation d'\u00e9chantillons physiques<\/h3>\n\n\n\n
Pr\u00e9parez deux ou trois options r\u00e9alistes plut\u00f4t que vingt petits \u00e9chantillons de couleur. Utilisez le profil n\u00e9on pr\u00e9vu et les mat\u00e9riaux de production.<\/p>\n\n\n\n
\u00c9tape 6 : Valider en conditions r\u00e9elles<\/h3>\n\n\n\n
V\u00e9rifiez l'\u00e9chantillon allum\u00e9 et \u00e9teint, de jour comme de nuit, \u00e0 diff\u00e9rents niveaux de luminosit\u00e9 et par rapport \u00e0 la surface de montage pr\u00e9vue.<\/p>\n\n\n\n
\u00c9tape 7 : Fixer la norme de production<\/h3>\n\n\n\n
Consignez les composants s\u00e9lectionn\u00e9s, les mesures, les r\u00e9glages du r\u00e9gulateur, les photographies, les signatures d'approbation et la proc\u00e9dure de remplacement.<\/p>\n\n\n\n
Tout le reste n'est que d\u00e9coration inspir\u00e9e par la m\u00e9moire.<\/p>\n\n\n\n
Foire aux questions<\/h2>\n\n\n\nQuelle couleur de n\u00e9on LED convient le mieux \u00e0 l'enseigne d'une marque ?<\/h3>\n\n\n\n
La meilleure couleur de n\u00e9on LED pour une enseigne de marque est celle qui permet de pr\u00e9server la reconnaissance de la marque, qui contraste avec la surface de fixation, qui reste lisible \u00e0 la distance pr\u00e9vue et qui peut \u00eatre reproduite de mani\u00e8re homog\u00e8ne d'un lot de production \u00e0 l'autre, sur les \u00e9l\u00e9ments de remplacement, sur les photographies et dans tous les lieux o\u00f9 l'enseigne sera install\u00e9e.<\/p>\n\n\n\n
Pour de nombreux logos permanents, la bonne r\u00e9ponse est la version lumineuse la plus fid\u00e8le possible \u00e0 la couleur d'entreprise approuv\u00e9e \u2014 et non l'option la plus vive ou la plus tendance du nuancier du fournisseur.<\/p>\n\n\n\n
Un fabricant de n\u00e9ons LED peut-il reproduire exactement une couleur Pantone ou HEX ?<\/h3>\n\n\n\n
Une valeur Pantone, CMJN, RVB ou HEX ne peut \u00e0 elle seule garantir une correspondance parfaite avec un n\u00e9on \u00e0 LED, car l'encre d'impression, la couleur de l'\u00e9cran, la diffusion par silicone, le spectre des LED, la luminosit\u00e9, la lumi\u00e8re ambiante et le traitement par l'appareil photo produisent des couleurs diff\u00e9rentes ; validez le choix final \u00e0 l'aide d'un \u00e9chantillon physique \u00e9clair\u00e9, fabriqu\u00e9 \u00e0 partir des mat\u00e9riaux pr\u00e9vus.<\/p>\n\n\n\n
Le fabricant doit utiliser les valeurs num\u00e9riques comme r\u00e9f\u00e9rences, puis fournir un \u00e9chantillon et indiquer le mod\u00e8le de LED, le profil\u00e9 en silicone, la puissance et la chromaticit\u00e9 retenus, dans la mesure du possible.<\/p>\n\n\n\n
Les n\u00e9ons \u00e0 LED RVB sont-ils meilleurs que les n\u00e9ons \u00e0 LED monochromes ?<\/h3>\n\n\n\n
Le n\u00e9on \u00e0 LED RVB est particuli\u00e8rement adapt\u00e9 lorsque des changements de couleur programm\u00e9s, des campagnes, des \u00e9v\u00e9nements ou une ambiance modulable font partie des exigences r\u00e9elles du projet, tandis que le n\u00e9on monochrome fixe est g\u00e9n\u00e9ralement pr\u00e9f\u00e9rable pour les enseignes d'identit\u00e9 permanentes, car il est plus simple \u00e0 valider, plus facile \u00e0 reproduire et moins susceptible de s'\u00e9carter des normes de la marque.<\/p>\n\n\n\n
Le mode RGBW est pr\u00e9f\u00e9rable lorsque la conception n\u00e9cessite \u00e9galement une sortie blanche exploitable, mais les valeurs du contr\u00f4leur et les limites de luminosit\u00e9 doivent alors \u00eatre consign\u00e9es.<\/p>\n\n\n\n
Quelle est la diff\u00e9rence entre un n\u00e9on LED \u00ab blanc chaud \u00bb et un n\u00e9on LED \u00ab blanc froid \u00bb ?<\/h3>\n\n\n\n
Le n\u00e9on LED \u00ab blanc chaud \u00bb d\u00e9signe g\u00e9n\u00e9ralement une lumi\u00e8re blanche dont la temp\u00e9rature de couleur se situe entre 2 700 K et 3 000 K, le \u00ab blanc neutre \u00bb se situe g\u00e9n\u00e9ralement entre 3 500 K et 4 500 K, et le \u00ab blanc froid \u00bb commence g\u00e9n\u00e9ralement vers 5 000 K ; cependant, le kelvin ne d\u00e9crit que la lumi\u00e8re blanche nominale et ne doit jamais \u00eatre utilis\u00e9 pour sp\u00e9cifier des couleurs satur\u00e9es telles que le rouge, le bleu, le vert ou le violet.<\/p>\n\n\n\n
Le blanc chaud convient souvent aux int\u00e9rieurs destin\u00e9s \u00e0 l'h\u00f4tellerie et aux espaces haut de gamme. Le blanc neutre est un choix commercial par d\u00e9faut plus s\u00fbr. Le blanc froid ne doit \u00eatre choisi que si la marque et l'\u00e9clairage ambiant s'y pr\u00eatent.<\/p>\n\n\n\n
Comment les couleurs des n\u00e9ons \u00e0 LED doivent-elles \u00eatre valid\u00e9es avant la fabrication ?<\/h3>\n\n\n\n
La couleur des LED n\u00e9on doit \u00eatre valid\u00e9e en comparant un \u00e9chantillon de mat\u00e9riau de production \u00e0 la fois allum\u00e9 et \u00e9teint, en l'observant contre un mur r\u00e9el ou simul\u00e9 sous un \u00e9clairage diurne et nocturne, en v\u00e9rifiant plusieurs niveaux de gradation, en le photographiant avec une exposition contr\u00f4l\u00e9e, et en consignant la configuration approuv\u00e9e des LED, du silicone, du contr\u00f4leur et de l'alimentation \u00e9lectrique.<\/p>\n\n\n\n
Pour les commandes r\u00e9p\u00e9titives, conservez l'\u00e9chantillon physique valid\u00e9 et attribuez-lui un code de projet ou un code d'\u00e9chantillon de r\u00e9f\u00e9rence.<\/p>\n\n\n\n
Les couleurs des n\u00e9ons LED s'estompent-elles ou changent-elles avec le temps ?<\/h3>\n\n\n\n
Les couleurs des n\u00e9ons \u00e0 LED peuvent varier ou sembler incoh\u00e9rentes, car les bo\u00eetiers de LED, le silicone ou les mat\u00e9riaux optiques, la temp\u00e9rature, le courant d'alimentation, les classes de fabrication, le vieillissement et les lots de remplacement ont une incidence sur la chromaticit\u00e9 ; les acheteurs doivent donc v\u00e9rifier l'\u00e9chantillon approuv\u00e9, les r\u00e9f\u00e9rences des composants, le lot de production, le courant de fonctionnement et la tol\u00e9rance acceptable en mati\u00e8re de couleur, qu'elle soit visuelle ou mesur\u00e9e.<\/p>\n\n\n\n
Les projets destin\u00e9s \u00e0 l'ext\u00e9rieur doivent \u00e9galement pr\u00e9voir l'utilisation de mat\u00e9riaux r\u00e9sistants aux UV, des temp\u00e9ratures de fonctionnement adapt\u00e9es, un syst\u00e8me de drainage, des passages de c\u00e2bles \u00e9tanches et un indice de protection IP65 ou IP67 adapt\u00e9 en fonction de l'installation.<\/p>\n\n\n\n
Valider les couleurs avant la production<\/h2>\n\n\n\n
Ne passez pas de commande de n\u00e9on LED commercial en fournissant uniquement un fichier de logo et la consigne \u201c faites-le en rouge de la marque \u201d.\u201d<\/p>\n\n\n\n
Envoyez au fabricant votre fichier graphique vectoriel, les r\u00e9f\u00e9rences de votre marque, les dimensions, les photos d'installation, le mat\u00e9riau du mur, la distance de visionnage, la tension, les conditions d'utilisation (int\u00e9rieur ou ext\u00e9rieur), le mode de commande souhait\u00e9 et le pays de livraison. Demandez ensuite un \u00e9chantillon lumineux ou une validation des couleurs document\u00e9e avant de valider le lot de production.<\/p>\n\n\n\n
Consultez les options disponibles Options de fabrication de n\u00e9ons LED sur mesure<\/a> et Envoyez-nous vos sp\u00e9cifications de signal\u00e9tique pour obtenir un devis d'usine<\/a>. Un \u00e9chantillon contr\u00f4l\u00e9 co\u00fbte bien moins cher que le remplacement d'une enseigne de marque g\u00e9n\u00e9rique apr\u00e8s son installation.<\/p>\n\n\n\n<\/p>","protected":false},"excerpt":{"rendered":"
