Depending on how it is utilized, sign illumination may either enhance the sign’s efficacy or render it completely illegible and ineffective—but it is frequently overlooked or used incorrectly. In this article, I will introduce the reader to the fundamentals of the connection between architectural lighting and lighting for signs and graphics in general, to facilitate the reader’s understanding of the topic.
The lighting of signs is often a practical component, a need that is taken for granted. Nonetheless, light is used as a versatile design element by architects and sign designers. Light from a variety of sources may be used to better define shapes and areas, as well as highlight finer details. When employed imaginatively, artificial light has the power to evoke a wide range of emotional responses. The exciting, dramatic emphasis and emotional warmth may be achieved, especially when combined with colored walls.
50W LED Floodlights are often used at night to highlight significant architectural works. Improving a company’s public image includes illuminating the façade of its headquarters office building. In addition to the external sign’s illumination. If the signs are constructed and placed correctly, the project’s existing lighting may be utilized to illuminate the signage.
When it comes to the illumination of outdoor signage for buildings, there are a few different tried-and-true methods to choose from. There are many different types of lighting, including bright, direct illumination, soft, ambient illumination, and dark, exterior illumination. Spill light from preexisting or supplemental floodlights may be used to illuminate outside signage or inscriptions that are either cast into the building wall or fitted flush with it. An excellent and understated method to distinguish respectable workplaces, this is.
Floodlighting raised, three-dimensional lettering of any thickness requires special attention to ensure readability, since shadows created by the letters might obscure the text. A typical issue with signing is the shadows created by such letters under both natural light and artificial lighting sources. The designer, however, often can triumph over such obstacles by selecting the appropriate material or finish. If you install some shiny metal or bronze letters on a structure made of black granite, for instance, they will be easily readable no matter the lighting circumstances. When creating a new sign, the designer must constantly take the existing lighting conditions in mind, making any necessary adjustments so that the sign and its surroundings are harmonious.
Large, prominent identifying signs are sometimes necessary for some projects, however, they are often placed in inappropriate areas to be illuminated by floodlights. The “trough” is a glass diffuser that is installed in a depression next to a pathway for safety. This structure conceals a continuous light source that evenly illuminates the whole sign. Traditional spotlights would have cast shadows and produced glare and hot spots.
For much pedestrian-oriented signage, ambient lighting—in the form of spill light from existing architectural lighting—may provide sufficient illumination. The address numbers or identification signs at a building’s enterance, for instance, may be lighted by spill light from overhead entry lights if the colors and materials of these signs contrast effectively against their backgrounds.
In many situations, the level of available light is crucial. Parking entry signs often need interior lighting in parking lots when conventional light standards may only give a few foot candles of illumination. To be readable at night or to add emphasis, external signage typically needs inside illumination. We manufacture a wide variety of illuminated signs, but most of our commercial clients think that channel letter signs illuminated from the inside are the most effective.
