Electric Signs can be classified into two groups.
Luminous – Letter Signs: A sign that has illuminated letters and a non-illuminated background.
Luminous – Element Signs: A sign with panels of translucent plastic or glass that is illuminated by an interior light source. The plastic or glass panel is either integrally pigmented, externally painted, or opaque. The pigmenttation or paint film acts as a diffuser for the light providing uniform brightness across the sign face.
Factors to Consider:
Speed of Recognition: The brightness of either the letters or the background, or the contrast between the letters and background. Brightness and contrast attract attention.
Sign Readability: A sign’s face that is too bright will suffer loss of readability from the halo effect around the letters. An insufficiently lit sign reduces the legibility distance of the sign face.
Attractiveness: Opaque letters on a light background are generally suggested if attractiveness is your major concern, such as in many commercial signs.
Communication: If communication is the major factor, very light letters on a dark background are suggested.
Light Source Factors:
Light Source Selection Factors:
- Brightness required
- Sign shape and size
- Desired color effects
- Environmental temperature and conditions
- Service access requirements
- Fluorescent lamps are a good choise of light source as the light source is linear and does not need the aid of a diffuser
