5552002 Optoelectronics

LEDs – Circuit Board Indicators, Arrays, Light Bars, Bar Graphs – have been utilized for decades for a wide variety of applications. The 5552002 device, developed and manufactured by Avago Technologies, offers a number of advantages that make it among the most popular and refined circuit board indicators available on the market today. This article will provide an overview of the 5552002, focusing on its capabilities, applications and working principles.

Product Overview

At first glance, the 5552002 may not seem like the most exciting LED, but potentially its biggest asset is the design flexibility it offers for circuit board applications. The small size and low wattage (0.7V max) means it can be placed in a wide array of small spaces, while also requiring minimal power. The 5552002 also offers a range of 3000K (warm white) and 6500K (daylight white) color temperatures, making it suitable for a variety of applications.

One of the most convenient features of the 5552002 is the wide range of brightness settings available. It has a range of 20-200 lumens, with a maximum brightness of 2350 mcd (millicandelas). This allows the circuit board to be adjusted according to the situation’s level of brightness requirements.

In addition to its design flexibility, the 5552002 also features a long life span of up to 50,000 hours. This ensures that it can be used for extended periods of time without the need for frequent replacements.

Working Principle

The 5552002 operates on two insulated circuits: a constant current source, and a pulse width modulation system. The constant current source ensures that the LED driver maintains a consistent output of voltage and current, regardless of load variations or electrical environment. This allows the circuit board to be used in a range of applications.

The pulse width modulation system is responsible for controlling the output voltage, current and light intensity of the LED. This system adjusts the pulse width of the signal going to the driver, which in turn adjusts the intensity of the LED. By varying the pulse width, the LED can be adjusted to achieve the desired level of brightness.

Application Field

Due to its versatility, the 5552002 LED is suitable for a wide range of applications. It is frequently used in automotive lighting, displays, touch pads, keypads and LEDs indicators. This LED is also widely used in the medical industry for imaging, diagnostic and surgical equipment. Additionally, it is used in the industrial sector for decorative lighting and signage.

Conclusion

Overall, the 5552002 LED is a highly versatile circuit board indicator that offers a wide range of design possibilities. Its small size, low wattage and long-life span make it ideal for a variety of applications. In addition, the variable brightness settings and wide color-temperature range make it an ideal choice for medical and industrial applications. By utilizing a combination of a constant current source and pulse width modulation system, the 5552002 is able to provide consistent, reliable performance for long periods of time.
