A1D-T

A1D-T is a type of sign lighting that first appeared in the 1980s and is a combination of the letters “A” and “D”. A1D-T is short for “accentuated direct Tungsten halogen” lighting, and it uses incandescent and neon lighting in combination. It is used as a lighting source for signs and other advertisement mediums in dark environments.

The two main light sources used in A1D-T lighting are incandescent and neon lamps. Incandescent lamps provide a bright white light at a relatively low voltage and current. This light is perfect for the front of a sign where maximum visibility is desired. The other component of A1D-T is a neon lamp, which emits a bright colored light when high voltage and current is applied. This light is perfect for the back of a sign or other advertisement environment.

The working principle of A1D-T lighting is simple. A high voltage power supply is used to power the two lamps. The incandescent lamp is connected to the main power supply and the neon lamp is connected to a separate circuit. The separate circuit provides the necessary voltage and current to the neon lamp, while the main power supply provides the necessary voltage and current to the incandescent lamp.

The combination of the two types of lamps allows for a more varied and creative way to light up a sign or advertisement medium. A1D-T lighting offers a wide variety of color combinations that cannot be achieved with any other type of lighting. It is also more energy efficient than other types of lighting, making it suitable for long-term outdoor applications.

A1D-T lighting has revolutionized the way in which signs and other forms of advertising are illuminated. Its combination of incandescent and neon lighting offers a wide variety of color combinations and a more energy-efficient alternative to other forms of lighting. It has become a popular choice for many businesses looking for a reliable and efficient lighting solution.
