LEDs have wide range of applications from digital displays, desktop devices to various creative lighting solutions. They have become increasingly popular for use in circuit board indicators, arrays, light bars, and bar graphs.

In this article, we will be examining the fields of application and working principles of LTM1205GC, a product from Linear Technology\'s family of Thin Bright LEDs.

Fields of Application

The LTM1205GC is ideal for use in applications requiring a wide viewing angle and a long life span. It\'s lightweight and compact size make it suitable for installation in tight spaces that require lots of illumination, while keeping the board level.

The LTM1205GC is primarily used in the following types of circuit board indicators, arrays, light bars, and bar graphs:

• LED indicators - to provide a visual cue that something has happened, or to indicate current status.
• Light arrays - to brightly point out and highlight certain features or key areas of information.
• Light bars - to show and direct attention along a timeline or plot.
• Bar graphs - to provide a quick, visual comparison of multiple values.

This LED is also used in many other applications, such as status displays, navigation systems, and data logging. It is also ideal for use in automotive applications, as it is a waterproof LED, meaning it can withstand water and salt spray.

Working Principle

The LTM1205GC is a thin panel LED with a wide viewing angle. It is a highly efficient, low-voltage device which operates at 9V with a maximum forward current of 50 mA.

The LED emits light in the visible spectrum with a wide beam width, making it ideal for lighting up a large area. As it is a waterproof LED, it can be used in outdoor applications and even in wet areas, such as bathrooms and showers.

The brightness of the LED is regulated by pulse-width modulation (PWM), which is a technique for controlling the brightness of the LED by varying the width and frequency of pulses. The duty cycle of the PWM signal determines the brightness of the LED.

The LTM1205GC also supports the use of an external current control circuit. In this circuit, an external resistor is used to control the current flow through the LED, which is useful for controlling the brightness of the LED.

Conclusion

The LTM1205GC is a highly efficient and compact LED which can be used in a variety of applications including indicators, arrays, light bars, and bar graphs. It is ideal for use in automotive and outdoor applications due to its waterproof design. Its wide viewing angle and long lifespan make it an excellent choice for lighting up a large area.

The brightness of the LED can be controlled by pulse-width modulation and an external current control circuit.
