Light box with graphic and/or text commercial information is considered to be one of the most popular outdoor advertising. Due to the fact there are many various techniques how to make a light box it can be used in a large variety of ways. Large light boxes can be used as a frontal sign-plate or an outdoor advertising board while smaller units serve as an excellent feature of shop window design or interior whereas models with the replaceable information panels are perfect for short-term promotional campaigns such as seasonal sales.
Three-dimensional channel letters relate to the type of advertising which is most difficult to manufacture yet it stands out due to substantiality, colorfulness and emphaticalness.
They can be front lit, backlit or both, as well as edge lit or fully lit, depending on the shape of the logo, application, customer needs and operating environment. Letters can be made of plastic (for indoor use) or aluminium (for outdoor use) and are lit by neon or LEDs.
Both lighting types have several advantages which are carefully evaluated before choosing the most suitable one for each project.
Dimensional letters are any elements of signage, which have a third dimension — depth, which ranges from just a few millimeters to twenty or more centimeters. For example channel letters can also be described as dimensional letters but with a built-in lighting. The range of depth may vary widely, and therefore there are numerous methods and materials for manufacturing of dimensional letters. We will expand on those, which are worth mentioning.
Neon signs are made using neon tubes without any cover over it. Typical sign is a set of tubes in the shape of letters that are fixed to a black aluminium frame or transparent Perspex.
Surely, neon can be used for illumination of channel letters or to outline the letter, yet such product will be referred to as channel or illuminated letters.
As it can be seen from the pictures, neon tube can be any colour you need. It is worth taking a note that there are white and even transparent tubes (the glass itself, physically) that have different colours when lit. This is achieved by combining different gases that fill the tube and fluorescent paint that it is covered with. It is possible to use the tubes made of coloured glass. Usually these tubes have deeper and richer color, but the sign made of coloured tubes would cost several times more.
