LEDs - Circuit Board Indicators, Arrays, Light Bars, Bar Graphs:

Light Emitting Diodes (LEDs) are used in many applications due to their long life, efficient energy output and relatively low cost. LEDs are used in the automotive, medical and human machine interface (HMI) industries for transmitting light signals or alerting users of a problem. LED arrays, light bars, and bar graphs are also used in the industrial and scientific industries for similar purposes.

LEDs have been used in circuit board indicators for decades. These indicators consist of a single LED and may be used to indicate the status of a circuit. They can communicate whether a system is on or off, in the process of powering up, or in some cases, indicate an emergency condition. Although there may be an array of LEDs used, typically the indicator is either illuminated or not. They are easy to install and use very little energy.

LED arrays are used in a variety of applications to serve as directional indicators. These arrays are typically used in higher intensity applications such as clearly marking exit signs, as indicators in billiard tables, or as backlighting in custom displays. LED arrays consume very little energy, yet still provide a bright light output.

Light bars are used where illumination and greater visibility is needed to direct people or mark obstacles in a dark environment. Light bars are used in industrial, commercial and home applications. They are typically equipped with multiple LED arrays that are visible even in bright sunlight. The number of LED arrays and their type will depend on the application and desired effect.

Bar graphs are directional indicators that consist of multiple LED segments that light up depending on the application. They are used in applications such as audio visual displays and panel meters. They can also be used to indicate a predetermined level or to give visual feedback to the user. Bar graphs are generally easier to read than arrays or indicators.

LEDs are versatile devices that are used in a variety of applications and circuit board indicators, arrays, light bars, and bar graphs are all utilized for similar purposes. LED arrays provide directional illumination, light bars provide visibility in dark conditions and bar graphs provide visual feedback for audio visual display. All three serve to enhance the user experience and can be added to existing displays in an affordable and effective manner.
